The Patients are organized by Patients Code. So we should be able to look in the File for Patient “A900”, and it should give us back all the data about that Patient, like, Patinet Id, etc. So we will need to read from the “Patients.txt” file and select the Patient Id “A900”. The File is delimited by “:”(colons). Take a look at the file. use FileInputStream and Buffered reader to read from the file. Code for testing ‘Select’ that goes in main: Patient p1 = new Patient(); p1.select(“A900”); p1.display(); Let’s also make it so that we can add a new Patient to the “Patients.txt” file.use PrintStream and Buffered writer to write to the file. We should be able to append a new line to the “Patients.txt” file with all the data for a new Patient, like PatientId,etc. Code for testing ‘Insert’ that goes in main: Patient p1 = new Patient(); p1.insert(“A900\",\"1234\",\"Jimmy:Hawkins\",\"Marietta\",\"jhawk@yahoo.com\",\"Cigna\"); //now go look in file to see if new line was added Solution import java.util.*; public class Patient { private int patientId; private String patientName; private String patientAddress; private String patientPhone; private Date patientDOB; public Patient(int patientId, String patientName, String patientAddress, String patientPhone, Date patientDOB) { // initialise instance variables this.patientId = patientId; this.patientName = patientName; this.patientAddress = patientAddress; this.patientPhone = patientPhone; this.patientDOB = patientDOB; } public void setId (int patientId) { this.patientId = patientId; } public void setName (String patientName){ this.patientName = patientName; } public void setAddress (String patientAddress){ this.patientAddress = patie.

Linq And Its Impact On The.Net Framework
A brief overview of LINQ and an analysis of the enhancements its introduction imposed on the .NET Framework
programming Code in C thatloops requesting information about patie.pdf
programming Code in C that
loops requesting information about patients and inserting the information into a linked list:
call a function responsible for allocating the memory for the new item, requesting the following
information for each patient: first name, last name, and patientid (an integer), and putting the
information into the new item
the function mentioned in part a should return a pointer to the new item
call a function to insert the new item into the linked list
new patients should be added so that the list is in alphabetical order by the last name
leave the loop when the patient id is set to 0
displays the patient information in alphabetical order by the last name once all data has been
provided. The first and last name and patient id for each patient should be displayed

Ive already completed the Java assignment below, but it doesnt wor.pdf
I've already completed the Java assignment below, but it doesn't work. I will include my code
and the tests. Please correct my code and tests to that they match what has been asked and
reached 95% test coverage as asked for in the assignment.
Assignment: Disease File Repository
This assignment is a continuation of the last assignment. Please use the Eclipse project that you
created in the first assignment for this work.
Source Code
Class: Exposure
Copy the Exposure class from the previous assignment into the new. Make the necessary
changes so that this class can be serialized.
Class: Patient
Copy Patient class from the previous assignment into the new. Make the necessary changes so
that this class can be serialized and that it uses the Exposure class class.
Class: Disease
Copy the Disease, the InfectiousDisease, the NonInfectiousDisease classes from the previous
assignment into the new. Make the necessary changes so that they can be serialized.
Class: DiseaseAndPatient
Create a class called DiseaseAndPatient and define the follwing properties:
private Disease[] diseases;
private Patients[] patients;
Create getter and setter methods for the two arrays and document the new methods using the
Javadoc standard.
Class: DiseaseFileRepository
Create a class called DiseaseFileRepository and define the following methods:
DiseaseAndPatient init(String folderPath)
This method accepts a file path to the folder where the data was serialiaed and set the folder path
to a propert on this class. Deserialize the disease data from the file named diseases.dat.
Deserialize the patient data from the file named patients.fat. Set both the deserialized disease and
patient arrays to an instance of the DiseaseAndPatient class and return that instance. Throw an
IllegalArgumentException with an appropriate message if the supplied folder path is null.
void save(Disease[] diseases, Patient[] patients)
This method serializes and saves the supplied disease and patient array data to two separate files
on the file system using the folder path from the init method. Serialize the disease array data to a
file named disease.dat and the patient array data to the file name patients.dat.
Documentation
You are required to document the class, constructor, and methods using Javadoc standard.
Class: DiseaseFileRepositoryTest
Create a class called DiseaseFileRepositoryTest to test your DiseaseFileRespository class. You
must achieve at least 95% test coverage on the DiseaseFileRepository class.
Class: DiseaseControlManager and DiseaseControlManagerImpl
Copy the DiseaseControlManager interface and the DiseaseControlMangerImpl class from the
previous assignment and into the new. The DiseaseControlManager implementation will use the
DiseaseFileRepository class that you created in this assignment to initialize and save the disease
and patient data.
Constructor
Add a DiseaseFileRepository property to the DiseaseControlManager implementation and
initialize the property in the constructor of the D.
Implementing CQRS and Event Sourcing with RavenDB
CQRS stands for Command Query Responsibility Segregation. That is, that command stack and query stack are designed separately. This leads to a dramatic simplification of design and potential enhancement of scalability.
Events are a new trend in software industry. In real-world, we perform actions and these actions generate a reaction. Event Sourcing is about persisting events and rebuilding the state of the aggregates from recorded events.
In this talk I will share a lot of examples about how to effective implementing CQRS and Event Sourcing with RavenDB

Ive already completed the Java assignment below, but it doesnt wor.pdf
I've already completed the Java assignment below, but it doesn't work. I will include my code
and the tests. Please correct my code and tests to that they match what has been asked and
reached 95% test coverage as asked for in the assignment.
Assignment: Disease File Repository
This assignment is a continuation of the last assignment. Please use the Eclipse project that you
created in the first assignment for this work.
Source Code
Class: Exposure
Copy the Exposure class from the previous assignment into the new. Make the necessary
changes so that this class can be serialized.
Class: Patient
Copy Patient class from the previous assignment into the new. Make the necessary changes so
that this class can be serialized and that it uses the Exposure class class.
Class: Disease
Copy the Disease, the InfectiousDisease, the NonInfectiousDisease classes from the previous
assignment into the new. Make the necessary changes so that they can be serialized.
Class: DiseaseAndPatient
Create a class called DiseaseAndPatient and define the follwing properties:
private Disease[] diseases;
private Patients[] patients;
Create getter and setter methods for the two arrays and document the new methods using the
Javadoc standard.
Class: DiseaseFileRepository
Create a class called DiseaseFileRepository and define the following methods:
DiseaseAndPatient init(String folderPath)
This method accepts a file path to the folder where the data was serialiaed and set the folder path
to a propert on this class. Deserialize the disease data from the file named diseases.dat.
Deserialize the patient data from the file named patients.fat. Set both the deserialized disease and
patient arrays to an instance of the DiseaseAndPatient class and return that instance. Throw an
IllegalArgumentException with an appropriate message if the supplied folder path is null.
void save(Disease[] diseases, Patient[] patients)
This method serializes and saves the supplied disease and patient array data to two separate files
on the file system using the folder path from the init method. Serialize the disease array data to a
file named disease.dat and the patient array data to the file name patients.dat.
Documentation
You are required to document the class, constructor, and methods using Javadoc standard.
Class: DiseaseFileRepositoryTest
Create a class called DiseaseFileRepositoryTest to test your DiseaseFileRespository class. You
must achieve at least 95% test coverage on the DiseaseFileRepository class.
Class: DiseaseControlManager and DiseaseControlManagerImpl
Copy the DiseaseControlManager interface and the DiseaseControlMangerImpl class from the
previous assignment and into the new. The DiseaseControlManager implementation will use the
DiseaseFileRepository class that you created in this assignment to initialize and save the disease
and patient data.
Constructor
Add a DiseaseFileRepository property to the DiseaseControlManager implementation and
initialize the property in the constructor of the D.
Implementing CQRS and Event Sourcing with RavenDB
CQRS stands for Command Query Responsibility Segregation. That is, that command stack and query stack are designed separately. This leads to a dramatic simplification of design and potential enhancement of scalability.
Events are a new trend in software industry. In real-world, we perform actions and these actions generate a reaction. Event Sourcing is about persisting events and rebuilding the state of the aggregates from recorded events.
In this talk I will share a lot of examples about how to effective implementing CQRS and Event Sourcing with RavenDB

This is a java lab assignment. I have added the first part java re.pdf
This is a java lab assignment. I have added the first part \"java retail class\" at the bottom. I am
unsure how to read the txt file into an array from the retail class. The stock txt file has been
added also.
A beginning framework and inventory list has been provided to you to use your Retail Item Class
as an array. Develop a program to accomplish the following menu items that can be selected by
the end user. Discussion of what each menu item should do is provided below the menu item.
Modify your object class file as desired. Please append initials to files created. Use Select-Case
for menu choices and methods to perform those choices. Please make a selection: 1. Open
Inventory File (This should ask the user for the file name, open the file and load the data into the
object array). 2. Display All (This should show a table of all items and data) 3. Display Reorder
Only (This should show only the stock number, Description and current quantity for items
requiring reorder) 4. Find Stock number (Allows the user to enter part of the description and
displays all matching stock numbers and descriptions matching that - case insensitive, such as
“cubs” or “cubs”) 5. Display Stock number (Allows user to enter stock number and displays
record of item) 6. Add Quantity (Asks for stock number and quantity for units, adds it to current,
displays record results) 7. Subtract Quantity (Asks for stock number and quantity, subtracts,
displays results including if reorder is needed.) 8. Change Price (Asks for stick number, changes
price to provided value, display results). 9. New Item (Allows adding a new item, updates count.
Display record results). 10. Save Inventory File (asks user for file name, save all inventory to
that file in a format that can be read back.)

Adapt your code from Assignment 2 to use both a Java API ArrayList a.pdf
Adapt your code from Assignment 2 to use both a Java API ArrayList and a Java API LinkedList
and your new I_a (fish) objects from Assignment 3. The new program should have a main user
menu like in A2 with an added choice to print the list backwards. There should be a new
makeFish static method and a printing method similar to that in A2 renamed to printForwards
and one new method printBackwards.
Making Fish When making an I_a object in the makeFish method, instead of asking the user to
enter all the information as you did for Pokemon in A2, make a sub-menu for them to pick from
the 14 kinds of I_a implemented in A3
The only thing the user must choose is the I_a type and if they want to enter the length (or get a
random length) You should ask, Do you want to enter a length for your I'a, Y/N HINT: use
equalsIgnoreCase to simplify user input If they choose to enter the length then you will need to
ask for the length and convert the input to a double for the constructor.
You will need to try/catch for non-number and FishSizeException. This will need to loop until
you get a valid length. Finally use a switch to call the constructor for the chosen I_a. For
example: case 1: I_a ia = new Pua_ama(); or case 7: I_a ia = new PalaMoi(14.25); or case 9:I_a
ia = new Ohua(3.3));
Lists of Fish The program should have both a Java API ArrayList and LinkedList. You must
correctly declare both generic types to hold I_a objects. They should be local to the main method
(like the array in A2). Use the List interface to declare both list variables, then initialize as the
two different kinds of lists: List List1 = new ArrayList<>(); List List2 = new LinkedList<>();
Add each I_a the user makes to both lists. To add the first six I_a you can use the List Interface
add method: List.add(E element) This will add to the end (higher index) of both kinds of lists.
The allowed number of stored I_a should be limited to 6 like in the array in A2.
Don't let either List keep growing even though they can! The lists should work the same as in
A2, the 7th I_a should "wrap around" and overwrite the first I_a made (in index 0), and so on. To
overwrite existing elements using the List.set(int index, E element) method. Printing Lists The
printArray method from A2 should be renamed to printForwards, it should still be void, and
should take one parameter of type List instead of an array. The new printBackwards method will
be nearly identical, but will print a List in reverse index order: 5 4 3 2 1 0 Both methods must use
ListIterators to print the List contents. The printForwards method should get the ArrayList sent
to it from the menu choice to print the list and should print out just like the old array did,
forwards. The printBackwards method should have the LinkedList sent to it from the menu
choice to print the list backwards and should print out in REVERSE order.

LAB 9: INHERITANCE AND POLYMORPHISIM
SPRING 2017
Goal
In this assignment students will practice inheritance and polymorphism in C++.Objectives
Class Programming: Given an object-based entity with specific functionality, students should be able to create an equivalent C++ class to represent it.
Problem:
1. Add to class patientType the date when the patient was admitted in the hospital, and the date when the patient was discharged from the hospital (Use the class Date class you wrote in the prelab) to store admit date, discharge date. Modify constructors and add member functions to initialize access, and manipulate the new added data members.
2. In main(), create a vector of pointers to type TeamPerson. Fill it up with at least three objects. One of TeamPerson, one of doctorType and one of patientType.
3. Print all the data of the three objects of the vector. Make sure each object is printed according to its print function.

i need help to edit the two methods below so that i can have them wo.pdf
I have to make a program for my C class and im stuck on the part where i have to calculate the
variance with elements from my array. This is exactly what im suppose to do:
Reset the sum variable to 0
Using another for loop (which needs its own loop variable), run through all valid elements of the
array, starting from index 0. Inside the loop:
Use the sum variable to accumulate the numerator of the variance formula shown on page 1.
After the end of this loop, compute the variance by dividing the new sum by the
dataElementsToProcess parameter.
this is the entire function
bool GenerateStatistics(FILE *fp2, double myArray[], int dataElementsToProcess)
{
if (fp2 == NULL && myArray == NULL && dataElementsToProcess < 1)
{
return false;
}
else
{
int i = 0,o = 0;
int sum = 0, sum1 = 0;
double maxValue = 0;
double minValue = DBL_MAX;
double mean, variance, stdDeviation;
for (int i = 0; i < 600; i++)
{
sum += myArray[i];
if (myArray[i] > maxValue)
{
maxValue = myArray[i];
}
if (myArray[i] < minValue)
{
minValue = myArray[i]; }
}
mean = sum / dataElementsToProcess;
sum = 0;
for (int o = 0; o < 600; o++)
{
sum += myArray[o];
}
variance = sqrt(pow((sum - mean), 2) / (dataElementsToProcess));
stdDeviation = sqrt(variance);
fprintf(fp2, \"Reaction Rate Statistics:\ \ \");
fprintf(fp2, \"Number of experiments = %d\ \", dataElementsToProcess);
fprintf(fp2, \"Minimum rate\\t\\t= %f\ \", minValue);
fprintf(fp2, \"Maximum rate\\t\\t= %f\ \", maxValue);
fprintf(fp2, \"Arithmetic mean\\t\\t= %f\ \", mean);
fprintf(fp2, \"Variance\\t\\t= %f\ \", variance);
fprintf(fp2, \"Standard deviation\\t= %f\ \ \ \", stdDeviation);
}
return true;
}
Solution
Here in the function you have
average - mean
Noofelements - dataElementsTo Process
Variance formula is
V = summation over i=1 to n ((xi - mean )*(xi - mean))
So perform like this using a for loop over my_array
double V=0.0
for(int i=0;i<600;i++)
{
V=V+pow((my_Array[i]-mean),2)
}
Now calculate standard deviation using sqrt of variance
sd=0.0
sd=sqrt(V).
C++ ProgrammingSo I received help with a code that takes a diabet.pdf
C++ Programming:
So I received help with a code that takes a diabetics name, age, food consumed, and the blood
sugar (before and after) using linked lists and then copies the information to a file. How would I
make this so that the Person class only holds name and age, but then an inherited class Diabetic
takes the reigns and has name+age from Person and then adds the food, and blood sugar results?
Is that even possible with linked lists? And how would I create an option on whether user would
like to copy to a file instead of automatically copying it?

Below is my program, I just have some issues when I want to check ou.pdf
Below is my program, I just have some issues when I want to check out a patient and when I
want to print a specific patient. Please help. I think there is a minor error, but I can\'t find it.
PATIENT ID MUST BE \"LASTNAMEFIRSTNAMEYEAR\" example PattersonMathew2005.
Please read instructions help me solve the problem.
In this assignment, you will write a struct plus two simple classes and then write a program
that uses them all. The first class is a Date class. You are given code for this at the end of this
assignment, but you must make some modifications. The other is a Patient class; you are given
the class definition and you must write the implementation. The program will keep track of
patients at a walk-in clinic. For each patient, the clinic keeps a record of all procedures done.
This is a good candidate for a class, but to simplify the assignment, we will make a procedure
into a struct. We will assume that the clinic has assigned all care providers (doctors, nurses, lab
technicians) with IDs and each procedure (“office visit”, “physical exam”, “blood sample taken”,
etc.) also has an ID. Each patient will also have an ID, which is formed by the last name
concatenated with the first name and the year of birth. All other IDs (care providers, procedures)
will be just integers.
When the user runs the program at the start of the day, it first tries to read in from a binary file
calledCurrentPatients.dat. It will contain the number of patients(in binary format) followed by
binary copies of records for the patients at the clinic . This information should be read and stored
in an array of Patient objects. There will be a separate array, initially empty at the start of the
program that will store patient records for all patients who are currently checked in at the clinic.
It then asks the user to enter the current date and reads it in. It should then presents the user with
a simple menu: the letter N to check in a new patient, R for checking in a returning patient, O to
check out a patient, I to print out information on a particular patient, P to print the list of patients
who have checked in, but not yet checked out, and Q for quitting the program.
The following tasks are done when the appropriate letter is chosen.
N: The new patient’s first name, last name, and birthdate are asked for and entered. The new
patient ID will be the last name concatenated with the first name and the year of birth. (Example:
SmithJohn1998) The primary doctor’s ID is also entered. The new patient object is placed in
both arrays: one keeping all patients, and one keeping the patients who checked in today.
R: The returning patient’s ID is asked for, and the array holding all patients is searched for the
patient object. If found, a copy of the patient object is placed in the array for all currently
checked in patients. If not found, the user is returned to the main menu after asking them to
either try R again, making sure the correct ID was entered, or choose N to enter th.
Inheritance compiler support
In object-oriented programming, inheritance enables new objects to take on the properties of existing objects. A class that is used as the basis for inheritance is called a superclass or base class. A class that inherits from a superclass is called a subclass or derived class.
Objective Min-heap queue with customized comparatorHospital emerg.pdf
Objective: Min-heap queue with customized comparator
Hospital emergency room assign patient priority base on symptom of the patient. Each patient
receives an identity number which prioritizes the order of emergency for the patient. The lower
the number is, the higher the emergency will be.
Use java.util.PriorityQueue to write a java program to create the emergency room registration
database. The patient.txt is the input file for patient record. Download patient.txt, Patient.java to
perform following specifications:
(a)Load all records from the input file.
(b)At the end, print the list in assigned priority order.

A series RL circuit includes a 9.05-V battery, a resistance of R = 0.pdf
A series RL circuit includes a 9.05-V battery, a resistance of R = 0.755 , and an inductance of L
= 2.97 H. What is the induced emf 1.33 s after the circuit has been closed?
So, basically, I tried solving this equation using an RL circuit formula: I = emf/R(1-e^-t/(L/R))
and used V=IR to solve for the current, for which I plugged it back in to obtain the emf. I got an
answer of about 31, which was wrong. If you could help me on this, it would make my day!
Solution
tau = L/R = 2.97/0.755 = 3.9337
V = V0*e^(-t/tau)
V = 9.05*e^(-1.33/3.9337)
V = 6.453 V.
What is the dangling pointer Explain with a proper example.Solut.pdf
What is the dangling pointer? Explain with a proper example.
Solution
A dangling pointer is a pointer which nce pointed to some data, but because of memory
deallocation, points to an invalid or null data.
Example:
Suppose we declare and allocate some memory to a pointer:
char *temp = malloc(some_size);
Then we de-allocate the memory allocated to the pointer temp by,
free (temp);
After execution of the above statement, temp becomes a dangling pointer..

This is a java lab assignment. I have added the first part java re.pdf
This is a java lab assignment. I have added the first part \"java retail class\" at the bottom. I am
unsure how to read the txt file into an array from the retail class. The stock txt file has been
added also.
A beginning framework and inventory list has been provided to you to use your Retail Item Class
as an array. Develop a program to accomplish the following menu items that can be selected by
the end user. Discussion of what each menu item should do is provided below the menu item.
Modify your object class file as desired. Please append initials to files created. Use Select-Case
for menu choices and methods to perform those choices. Please make a selection: 1. Open
Inventory File (This should ask the user for the file name, open the file and load the data into the
object array). 2. Display All (This should show a table of all items and data) 3. Display Reorder
Only (This should show only the stock number, Description and current quantity for items
requiring reorder) 4. Find Stock number (Allows the user to enter part of the description and
displays all matching stock numbers and descriptions matching that - case insensitive, such as
“cubs” or “cubs”) 5. Display Stock number (Allows user to enter stock number and displays
record of item) 6. Add Quantity (Asks for stock number and quantity for units, adds it to current,
displays record results) 7. Subtract Quantity (Asks for stock number and quantity, subtracts,
displays results including if reorder is needed.) 8. Change Price (Asks for stick number, changes
price to provided value, display results). 9. New Item (Allows adding a new item, updates count.
Display record results). 10. Save Inventory File (asks user for file name, save all inventory to
that file in a format that can be read back.)

Adapt your code from Assignment 2 to use both a Java API ArrayList a.pdf
Adapt your code from Assignment 2 to use both a Java API ArrayList and a Java API LinkedList
and your new I_a (fish) objects from Assignment 3. The new program should have a main user
menu like in A2 with an added choice to print the list backwards. There should be a new
makeFish static method and a printing method similar to that in A2 renamed to printForwards
and one new method printBackwards.
Making Fish When making an I_a object in the makeFish method, instead of asking the user to
enter all the information as you did for Pokemon in A2, make a sub-menu for them to pick from
the 14 kinds of I_a implemented in A3
The only thing the user must choose is the I_a type and if they want to enter the length (or get a
random length) You should ask, Do you want to enter a length for your I'a, Y/N HINT: use
equalsIgnoreCase to simplify user input If they choose to enter the length then you will need to
ask for the length and convert the input to a double for the constructor.
You will need to try/catch for non-number and FishSizeException. This will need to loop until
you get a valid length. Finally use a switch to call the constructor for the chosen I_a. For
example: case 1: I_a ia = new Pua_ama(); or case 7: I_a ia = new PalaMoi(14.25); or case 9:I_a
ia = new Ohua(3.3));
Lists of Fish The program should have both a Java API ArrayList and LinkedList. You must
correctly declare both generic types to hold I_a objects. They should be local to the main method
(like the array in A2). Use the List interface to declare both list variables, then initialize as the
two different kinds of lists: List List1 = new ArrayList<>(); List List2 = new LinkedList<>();
Add each I_a the user makes to both lists. To add the first six I_a you can use the List Interface
add method: List.add(E element) This will add to the end (higher index) of both kinds of lists.
The allowed number of stored I_a should be limited to 6 like in the array in A2.
Don't let either List keep growing even though they can! The lists should work the same as in
A2, the 7th I_a should "wrap around" and overwrite the first I_a made (in index 0), and so on. To
overwrite existing elements using the List.set(int index, E element) method. Printing Lists The
printArray method from A2 should be renamed to printForwards, it should still be void, and
should take one parameter of type List instead of an array. The new printBackwards method will
be nearly identical, but will print a List in reverse index order: 5 4 3 2 1 0 Both methods must use
ListIterators to print the List contents. The printForwards method should get the ArrayList sent
to it from the menu choice to print the list and should print out just like the old array did,
forwards. The printBackwards method should have the LinkedList sent to it from the menu
choice to print the list backwards and should print out in REVERSE order.

Goal
In this assignment students will practice inheritance and polymorphism in C++.Objectives
Class Programming: Given an object-based entity with specific functionality, students should be able to create an equivalent C++ class to represent it.
Problem:
1. Add to class patientType the date when the patient was admitted in the hospital, and the date when the patient was discharged from the hospital (Use the class Date class you wrote in the prelab) to store admit date, discharge date. Modify constructors and add member functions to initialize access, and manipulate the new added data members.
2. In main(), create a vector of pointers to type TeamPerson. Fill it up with at least three objects. One of TeamPerson, one of doctorType and one of patientType.
3. Print all the data of the three objects of the vector. Make sure each object is printed according to its print function.

i need help to edit the two methods below so that i can have them wo.pdf
I have to make a program for my C class and im stuck on the part where i have to calculate the
variance with elements from my array. This is exactly what im suppose to do:
Reset the sum variable to 0
Using another for loop (which needs its own loop variable), run through all valid elements of the
array, starting from index 0. Inside the loop:
Use the sum variable to accumulate the numerator of the variance formula shown on page 1.
After the end of this loop, compute the variance by dividing the new sum by the
dataElementsToProcess parameter.
this is the entire function
bool GenerateStatistics(FILE *fp2, double myArray[], int dataElementsToProcess)
{
if (fp2 == NULL && myArray == NULL && dataElementsToProcess < 1)
{
return false;
}
else
{
int i = 0,o = 0;
int sum = 0, sum1 = 0;
double maxValue = 0;
double minValue = DBL_MAX;
double mean, variance, stdDeviation;
for (int i = 0; i < 600; i++)
{
sum += myArray[i];
if (myArray[i] > maxValue)
{
maxValue = myArray[i];
}
if (myArray[i] < minValue)
{
minValue = myArray[i]; }
}
mean = sum / dataElementsToProcess;
sum = 0;
for (int o = 0; o < 600; o++)
{
sum += myArray[o];
}
variance = sqrt(pow((sum - mean), 2) / (dataElementsToProcess));
stdDeviation = sqrt(variance);
fprintf(fp2, \"Reaction Rate Statistics:\ \ \");
fprintf(fp2, \"Number of experiments = %d\ \", dataElementsToProcess);
fprintf(fp2, \"Minimum rate\\t\\t= %f\ \", minValue);
fprintf(fp2, \"Maximum rate\\t\\t= %f\ \", maxValue);
fprintf(fp2, \"Arithmetic mean\\t\\t= %f\ \", mean);
fprintf(fp2, \"Variance\\t\\t= %f\ \", variance);
fprintf(fp2, \"Standard deviation\\t= %f\ \ \ \", stdDeviation);
}
return true;
}
Solution
Here in the function you have
average - mean
Noofelements - dataElementsTo Process
Variance formula is
V = summation over i=1 to n ((xi - mean )*(xi - mean))
So perform like this using a for loop over my_array
double V=0.0
for(int i=0;i<600;i++)
{
V=V+pow((my_Array[i]-mean),2)
}
Now calculate standard deviation using sqrt of variance
sd=0.0
sd=sqrt(V).
C++ ProgrammingSo I received help with a code that takes a diabet.pdf
C++ Programming:
So I received help with a code that takes a diabetics name, age, food consumed, and the blood
sugar (before and after) using linked lists and then copies the information to a file. How would I
make this so that the Person class only holds name and age, but then an inherited class Diabetic
takes the reigns and has name+age from Person and then adds the food, and blood sugar results?
Is that even possible with linked lists? And how would I create an option on whether user would
like to copy to a file instead of automatically copying it?

Below is my program, I just have some issues when I want to check ou.pdf
Below is my program, I just have some issues when I want to check out a patient and when I
want to print a specific patient. Please help. I think there is a minor error, but I can\'t find it.
PATIENT ID MUST BE \"LASTNAMEFIRSTNAMEYEAR\" example PattersonMathew2005.
Please read instructions help me solve the problem.
In this assignment, you will write a struct plus two simple classes and then write a program
that uses them all. The first class is a Date class. You are given code for this at the end of this
assignment, but you must make some modifications. The other is a Patient class; you are given
the class definition and you must write the implementation. The program will keep track of
patients at a walk-in clinic. For each patient, the clinic keeps a record of all procedures done.
This is a good candidate for a class, but to simplify the assignment, we will make a procedure
into a struct. We will assume that the clinic has assigned all care providers (doctors, nurses, lab
technicians) with IDs and each procedure (“office visit”, “physical exam”, “blood sample taken”,
etc.) also has an ID. Each patient will also have an ID, which is formed by the last name
concatenated with the first name and the year of birth. All other IDs (care providers, procedures)
will be just integers.
When the user runs the program at the start of the day, it first tries to read in from a binary file
calledCurrentPatients.dat. It will contain the number of patients(in binary format) followed by
binary copies of records for the patients at the clinic . This information should be read and stored
in an array of Patient objects. There will be a separate array, initially empty at the start of the
program that will store patient records for all patients who are currently checked in at the clinic.
It then asks the user to enter the current date and reads it in. It should then presents the user with
a simple menu: the letter N to check in a new patient, R for checking in a returning patient, O to
check out a patient, I to print out information on a particular patient, P to print the list of patients
who have checked in, but not yet checked out, and Q for quitting the program.
The following tasks are done when the appropriate letter is chosen.
N: The new patient’s first name, last name, and birthdate are asked for and entered. The new
patient ID will be the last name concatenated with the first name and the year of birth. (Example:
SmithJohn1998) The primary doctor’s ID is also entered. The new patient object is placed in
both arrays: one keeping all patients, and one keeping the patients who checked in today.
R: The returning patient’s ID is asked for, and the array holding all patients is searched for the
patient object. If found, a copy of the patient object is placed in the array for all currently
checked in patients. If not found, the user is returned to the main menu after asking them to
either try R again, making sure the correct ID was entered, or choose N to enter th.
Inheritance compiler support
In object-oriented programming, inheritance enables new objects to take on the properties of existing objects. A class that is used as the basis for inheritance is called a superclass or base class. A class that inherits from a superclass is called a subclass or derived class.

Objective: Min-heap queue with customized comparator
Hospital emergency room assign patient priority base on symptom of the patient. Each patient
receives an identity number which prioritizes the order of emergency for the patient. The lower
the number is, the higher the emergency will be.
Use java.util.PriorityQueue to write a java program to create the emergency room registration
database. The patient.txt is the input file for patient record. Download patient.txt, Patient.java to
perform following specifications:
(a)Load all records from the input file.
(b)At the end, print the list in assigned priority order.

A series RL circuit includes a 9.05-V battery, a resistance of R = 0.pdf
A series RL circuit includes a 9.05-V battery, a resistance of R = 0.755 , and an inductance of L
= 2.97 H. What is the induced emf 1.33 s after the circuit has been closed?
So, basically, I tried solving this equation using an RL circuit formula: I = emf/R(1-e^-t/(L/R))
and used V=IR to solve for the current, for which I plugged it back in to obtain the emf. I got an
answer of about 31, which was wrong. If you could help me on this, it would make my day!
Solution
tau = L/R = 2.97/0.755 = 3.9337
V = V0*e^(-t/tau)
V = 9.05*e^(-1.33/3.9337)
V = 6.453 V.
What is the dangling pointer Explain with a proper example.Solut.pdf
What is the dangling pointer? Explain with a proper example.
Solution
A dangling pointer is a pointer which nce pointed to some data, but because of memory
deallocation, points to an invalid or null data.
Example:
Suppose we declare and allocate some memory to a pointer:
char *temp = malloc(some_size);
Then we de-allocate the memory allocated to the pointer temp by,
free (temp);
After execution of the above statement, temp becomes a dangling pointer..

What’s Love Got To Do With It?
The Evolution of Human Mating
By Meredith F. Small
Reviewed By Michael S. Kimmel
When Tina Turner first bitterly asked “What’s love got to do with it?” her voice was so drenched
with pain and regret, the listener knew better than to believe her.
Not so Meredith Small. A physical anthropologist whose main research has been on primate
mating behavior, Small joins a coterie of such writers as Robert Ardrey, Desmond Morris and
Lionel Tiger, who have sought to make evolutionary biology the foundation of studies of sexual
behavior.
In “What’s Love Got To Do With It,” Small argues that we’re genetically programmed to
experience sexual pleasure; hard-wired to search for young, attractive mates; driven to copulate
“Way down deep, underneath all the love and lust, underlying the attachment and intimacy, is
DNA pushing us along”
Like those male writers, she claims that our genetic predisposition toward reproductive success is
the driving force of our sex-seeking behavior. And like them, she assumes that sex is a constant,
universal and relatively unchanging experience. But unlike them, Small places no value on
judgments on the strategies that individuals may adopt to achieve that reproductive success.
Women, she argues, are as sexual as men; homosexuality is as “normal” as heterosexuality.
Small exposes many of her colleagues’ conclusions as based more on myth than on evolution.
Take, for example, the familiar canard that men are “naturally” predisposed toward promiscuity,
while women are “naturally” monogamous. Males’ prodigious sperm production, the argument
goes, means that it is in men’s interest to fertilize as many women as possible. But women
produce only one egg at a time, and gestation and child care take an extraordinarily long time,
which means that it is in their interest to mate with only one man for life.
Not only do such arguments assume what they are trying to explain, but their assumptions are
wrong to begin with. Sperm and eggs do not have little personalities, complete with ambitions
and motivations. What’s more, the evidence actually tilts the other way. Female humans are
among the only mammals who conceal estrus; that is, they do not go into “heat” when they are
sexually receptive. They are potentially sexually receptive all through their cycle. What’s more, a
woman has a clitoris, which “exists only to receive and give off sexual pleasure.” What could be
the evolutionary function of that?
Small argues that it is just as likely that women may be designed to maximize their reproductive
chances by promiscuity. If they have sex with a large number of male partners, they can ensure
that their offspring will have a significant number of men who believe that they are the father,
and who will, therefore, protect the baby and provide it with food.
“The ability to move from male to male certainly improves a female’s chance of finding the best
genes for her future offspring,” Small writes.
Males, by contrast, wo.
What is the Surface characterization techniques of Fourier-transform.pdf
What is the Surface characterization techniques of Fourier-transform infrared spectroscopy
(FTIR) and Optical Imaging and Spectroscopy (microscopy, TIRF)
explain what are they measuring, their uniqueness, working principle briefly
Solution
Fourier transform infrared spectroscopy (FTIR) is a powerful analysis tool for characterizing and
identifying organic molecules. It is the spectroscopic technique that is the most widely used for
determining the characteristics of new membranes. In attenuated total reflectance mode, this type
of spectroscopy enables functional groups present over a depth of about 1 m to be identified.
During ATR analysis, the sample is kept in contact with a crystal allowing total internal
reflection. An infrared ray arrives at the crystal where the material under study has been placed.
The internal reflection of the ray in the crystal gives rise to an evanescent wave which, at each
reflection, continues beyond the surface of the crystal and penetrates the sample over about 1 m.
The penetration depth depends on the wavelength, the angle of incidence of the beam on the
crystal, and the nature of the crystal.
Spectra are thus obtained (curves of absorbance vs. wavelength) that have absorption peaks
characteristic of the functions present at the membrane surface.
FTIR-ATR is a sensitive, nondestructive method that can be used qualitatively and
quantitatively. However, it requires prior drying of the membrane sample.
One of the applications of FTIR-ATR is the characterization of modified surfaces. In this case,
the spectra show bands characteristic of the basic membrane with, in most cases, bands
characteristic of the new functional groups related to the modification. FTIR-ATR also enables
the efficiency of membrane cleaning to be assessed .
This method can also be used to analyze the adsorption of macromolecules at the membrane
surface and to check whether the conformation of the adsorbed compounds (e.g., proteins) has
been modified by comparing the spectra of the adsorbed product with those of the same product
in solution . When the deposits are very small, however, it is difficult to determine the presence
of fouling agents; this necessitates the use of elaborate data-processing methods that eliminate
the contributions of the membrane and water from the raw spectra.
UNIQUENESS:
There are three principal advantages for an FT spectrometer compared to a scanning (dispersive)
spectrometer.
TIRF
Total internal reflection fluorescence (TIRF) microscopy (TIRFM) is an elegant optical
technique that provides for the excitation of fluorophores in an extremely thin axial region
(‘optical section’). The method is based on the principle that when excitation light is totally
internally reflected in a transparent solid (e.g., coverglass) at its interface with liquid an
electromagnetic field, called the evanescent wave, is generated in the liquid at the solid-liquid
interface and is the same frequency as the excitation light. Since the inte.
What is the running time complexity and space complexity of the follo.pdf
What is the running time complexity and space complexity of the following procedure (n = R -
L + 1). Explain your answer. def foo(V, L, R): if L==R: return V[L] mid = (L+R)//2 m1 = foo(V,
L, mid) m2 = foo(V, mid+1, R) if m1==m2: return ml count1, count2 = 0, 0 for i in range(L,

count2 > (R-L+D/2: return m2 return None
Solution
We are removing half the data at each turn so time complexity is O(log n).
We divide it into 2 till we find 1. Thus,
1= N/2x
2x = N
Thus x = log2 n.

What are the security requirements and challenges of Grid and Cloud .pdf
What are the security requirements and challenges of Grid and Cloud Computing?
Solution
security issues:
A. Policies:
1) Inside Threats: good supervision should be done for having trusted employees .
2) Access Control:Digital signature can be implemented
for access control.
3) System Portability: The problem of vendor lock-in
should be handled .
B. Software Security:
1) Virtualization technology: up to date version of
virtualization product should be installed for the
security reasons.
2) Host Operating System:should be up to date and
secure from hackers
3) Guest Operating System: should be up to date and
secure from hackers
4) Data Encryption:should be done on all the data for
its safety.
C)Physical security:
1) Backup:Either a backup plan should be provided
automatically for each customer, or they can use the
plans provided elsewhere in the cloud.
2) Server Location:It should be at appropriate place. Room should have adequate space and
isolated. A
Cooling System and Fire Suppression System should
be installed there.
3) Firewall: Cloud Computing service providers should
provide a complete firewall solution to their clients.
Challenges:
A)No clear standard:Grid computing
uses various standards, but all grids are
not use same standards. Example all grid
operating system such as Linux, Apache,and My SQL are using WSRF,
WWW, SOAP and XML standards.
B)Distributed computing Vs Grid
computing: Grid computing involves
dynamic virtual organisation, resource
sharing and peer to peer computing. The
Grid intends to make access to
computing power, scientific data
repositories and experimental facilities
as easy as the Web makes access to
information. Same all facilities provide
the grid computing. So it is a challenge
for grid computing.
C)Lack of grid enabled software: The
software, which are enabled the grid
computing are less, It has limited
software on Grid. Much software has
not copyright issues and source code of
licence. It is need for more company
developing grid-enabled version, need
more developers on grid development
and need to develop open source
software.
D)Sharing Resources between Various
types of Services:Grid used for
sharing resource from various sites and
grid hosts. It handles a massive amount
of data as a grid platform. A lot of sites
and multiple servers gathered there it is
so complex infrastructure. It provides
difficulty for hardware resource sharing
within virtual organisation..

The organization of interrupted genes is often conserved between spe.pdf
The organization of interrupted genes is often conserved between species. What does this mean
and what is an example of this conservation (diagram/explain)?
Solution
First we have know about interrupted genes is often conserved between species,the intricate
cellular machinery that converts genetic information into functional protein and RNA molecules
and the many ways in which gene expression is regulated by the cell,we discuss some of the
ways that genes and genomes have evolved over time to produce the vast diversity of modern-
day life forms on our planet uncovering an astonishing wealth of information about the family
relationships among organisms and evolutionary mechanisms,but the great revelation of the past
20 years has been the discovery that the actual nucleotide sequences of many genes are
sufficiently well conserved that homologous genes.
The recognition of sequence homology has become a major tool for inferring gene and protein
function thus it is often possible to predict the function of a gene in humans for which no
biochemical or genetic information is available simply by comparing its sequence to that of an
intensively studied gene in another organism.
Gene sequences are often far more tightly conserved than is overall genome structure as
discussed features of genome organization such as genome size,cells do not have specialized
mechanisms for creating changes in the structures of their genomes evolution depends instead on
accidents and mistakes.
Introns can be detected by the presence of additional regions when genes are compared with their
RNA products by restriction mapping or electron microscopy
The positions of introns are usually conserved when homologous genes are compared between
different organisms but the lengths of the corresponding introns may vary greatly..

selective pressure A kind of virus that preferentially and exclusively infects bacterial cells A
circular clearing within a lawn of growth; surrounding a disk or colony containing an
antimicrobial
Solution
The basic principle of Enrichment is that of selection. Enrichment culture provides favourable
growth conditions for the organism of intrest and unfavourable conditions for the competing
organisms. This technique can be used in many ways. for example, if we want to culture a
thermophile bacteria, incubate the sample at high temperature i.e., at above 55 degrees
centigrade because at that temperature, only the thermophilic bacteria can grow while this
temperature hampers the growth of other bacteria in the sample.
Likewise, enrichment culture may also contains antimicrobial agents to which the selective
organism is resistant hence the required organism\'s growth is facilitated hampering the growth
of other organisms which are not resistant to the antimicrobial agent.
Enrichment culture may also contains pesticides or N2 (used for selective growth of nitrogen
fixing bacteria) depending upon the type of microorganism selected.
Hence the Answer is a lawn of bacteria is prepared and filter discs containing antimicrobial
agents are applied..

Q1) Show what part of SSL that protects against the following attack.pdf
Q1) Show what part of SSL that protects against the following attacks :-
a. Replay Attack: Earlier SSL handshake messages are replayed.
b. Man-in-the-Middle Attack: An attacker interposes during key exchange, acting as the client to
the server and as the server to the client.
c. IP Spoofing: Uses forged IP addresses to fool a host into accepting bogus data.
Q2) Describe the port forwarding operation. Using an example, describe the cases when it is very
useful, and the cases when it is very dangerous.
Solution
The secure socket layer (SSL) is a computer networking protocol that manages server
authentication, client authentication and encrypted communication between servers ant client
.
PROTACTION FROM REPLAY ATTACK-
The SSL itself is protected againsts replay attack using Medium Access Control ( MAC ). By
using MAC secret and the sequence number it ensures the communication integrity.
ssl handshake protocol
PROTECTION AGAINSTS MAN-IN-THE MIDDLE ATACK-
SSL is based on public/ private key cryptography. This basically means that there is a key pair.
The public key is used for encryption and secret key is used for decryption . A certificate is
basically a public key with a label identifying the owner. So when your browser connects to an
https server , the server will answer with its certificate. The browser checks if the certificate is
valid-
1: The owner information needs to match the server name that the user requested.
2: The certificate needs to be signed by a trusted certification authority.
if one of these condition is not met, the user is informed about the problem.
PROTECTION AGAINSTS IP SPOOFING-
An SSL certificate is specific to the particular domain for which it was created regardless of the
IP address of the doimain. So if a malicious entity want to attempt to redirect trafiic for a certain
website to their own malicious site through IP spoofing techniques. The fake site would not have
a SSL certificate that was accurately registerd to the real website.This can be varified through a
browser by viewing the certificate information and if the wrong address is shown, then the user
will know that they are not on the site they think they are on.Secure Socket Layer Architecture

The Roman Empire A Historical Colossus.pdf
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

Operation Blue Star - Saka Neela Tara
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

The Patients are organized by Patients Code. So we should be able to look in the File for Patient “A900”, and it should give us back all the data about that Patient, like, Patinet Id, etc. So we will need to read from the “Patients.txt” file and select the Patient Id “A900”. The File is delimited by “:”(colons). Take a look at the file. use FileInputStream and Buffered reader to read from the file. Code for testing ‘Select’ that goes in main: Patient p1 = new Patient(); p1.select(“A900”); p1.display(); Let’s also make it so that we can add a new Patient to the “Patients.txt” file.use PrintStream and Buffered writer to write to the file. We should be able to append a new line to the “Patients.txt” file with all the data for a new Patient, like PatientId,etc. Code for testing ‘Insert’ that goes in main: Patient p1 = new Patient(); p1.insert(“A900","1234","Jimmy:Hawkins","Marietta","jhawk@yahoo.com","Cigna"); //now go look in file to see if new line was added Solution import java.util.*; public class Patient { private int patientId; private String patientName; private String patientAddress; private String patientPhone; private Date patientDOB; public Patient(int patientId, String patientName, String patientAddress, String patientPhone,
