You are to write a GUI program that will allow a user to buy, sell and view stocks in a stock
portfolio.
Objective:
Write a GUI program that maintains a cash balance, list of stock holdings, supports buying and
selling of stocks and displays the current portfolio inventory.
Program Capabilities:
1. Allow a user to buy a stock with a given number of shares and price per share.
2. Display the current portfolio (stock ticker, number of shares, initial price).
3. Update the portfolio display for purchases and sales.
4. Allow the user to sell all of the shares of a given stock.
5. Give the user an initial cash balance, and update and display the balance according to the
user\'s purchases and sales.
6. Ignore any transaction that causes the cash position to go below $0.
USE OF PREVIOUS StockHolding and PortfolioList LABS IS ADVISED. (I\'ve including my
solutions to these below)
This is my written code from earlier homework:
public class StockHolding {
private String ticker;
private int numShares;
private double initialSharePrice;
private double currentSharePrice;
public StockHolding(String ticker, int numberShares, double initialPrice) {
this.ticker = ticker;
numShares = numberShares;
initialSharePrice = initialPrice;
currentSharePrice = initialPrice;
}
public double getCurrentValue() {
return numShares * getCurrentSharePrice();
}
public double getInitialCost() {
return numShares * getInitialSharePrice();
}
public double getCurrentProfit() {
return getCurrentValue() - getInitialCost();
}
public double getCurrentSharePrice() {
return currentSharePrice;
}
public void setCurrentSharePrice(double currentSharePrice) {
this.currentSharePrice = currentSharePrice;
}
public String getTicker() {
return ticker;
}
public int getShares() {
return numShares;
}
public double getInitialSharePrice() {
return initialSharePrice;
}
@Override
public String toString() {
return \"Stock \" + ticker + \", \" + numShares + \", shares bought at \"
+ initialSharePrice + \", current price \"
+ currentSharePrice;
}
}
AND
import java.util.ArrayList;
public class PortfolioList {
private ArrayList portfolio;
public PortfolioList() {
portfolio = new ArrayList();
}
public void add(StockHolding stock) {
portfolio.add(stock);
}
public StockHolding find(String ticker) {
for (int i = 0; i < portfolio.size(); i++) {
StockHolding sh = portfolio.get(i);
if (sh.getTicker().equals(ticker)) {
return sh;
}
}
return null;
}
public void remove(String ticker) {
int pos = -1;
for (int i = 0; i < portfolio.size(); i++) {
StockHolding sh = portfolio.get(i);
if (sh.getTicker().equals(ticker)) {
pos = i;
}
}
if (pos != -1) {
portfolio.remove(pos);
}
}
I\'ve been staring at this for two days, and I am lost. Please, any guidance/help would be greatly
appreciated.
Honestly don\'t even need a full solution, just need something to kick start. A comment skeleton
would help a ton. Thanks!

Write a program that mimics the operations of several vending machin.pdfeyebolloptics
Write a program that mimics the operations of several vending machines. More specifically, the
program simulates what happens when the user chooses one of the vending machines, inputs
money and picks an item from the vending machine. Assume there are two vending machines:
one for drinks and one for snacks. Each vending machine contains several items. The name,
price, and quantity of each item is given in two text files; one named “drinks.txt” for the drinks
vending machine and the other named “snacks.txt” for the snacks vending machine.
The format of the input values is comma-separated. The items listed should be organized in the
file with the following order: name, price, quantity. Here are some example items:
The actual reading and parsing of the input file is already handled in the class supplied to you
(see code on BlackBoard). You are given the variables as individual values. You will need to
create the .txt files for creating and testing your vending machines.
You will need to create/complete three classes for this homework assignment: Item,
VendingMachine, and VendingMachineDriver.
Problem Description
Milk,2.00,1
Within your VendingMachine class, include these methods:
VendingMachineThisconstructormethodwilltakeinthenameoftheinputfileand create a vending
machine object. A vending machine object will contain an array of Item objects called stock and
an amount of revenue earned. This constructor method has been completed for you and should
work appropriately once you have completed the rest of this class and the other class definitions.
vendThismethodwillsimulatethevendingtransactionafteravalidamountofmoney and an item
selection are entered. This method will decide if the transaction is successful (enough money or
item) and update the vending machine appropriately.
outputMessage This method will print an appropriate message depending on the success of the
transaction. If the user does not have enough money to buy the chosen item, the vending machine
should prompt the user to enter more money or exit the machine. If the vending machine is out of
the chosen item, the program will print an apology message and prompt the user to choose
another item or exit the machine. If there is enough money for the item selected, then the
vending machine will give the user the item and return the change.
printMenuThismethodprintsthemenuofitemsforthechosenvendingmachine. The Item class needs
to include the following data variables:
• description as a String
• price as a double
• quantity as an int
Within your VendingMachineDriver class, include a main method as the starting point for your
solution that creates the vending machine objects appropriately and then use a loop that
continues interacting with the vending machines until the user enters “X” to exit. See the sample
session for details.
As you implement your solution, you might find that some methods contain some repeated
coding logic. To avoid unnecessary redundancies in your code, have these method.

Assignment Overview:
This assignment requires you to complete various tasks involving classes you write with your partner. You
may also use classes that you find in the Java SDK.
The system that you will create is a Farmer’s Market Management System (FMMS). The FMMS is a tool
used by Dogwood Council to manage multiple Farmer’s Markets in their area. A Farmer’s Market may be
located at different sites, for different purposes (e.g. open-air market or indoor market, charity market,
community fundraising market, food swap market etc.) and different opening times.
Each Market has a name and is associated with a particular address and session time. Each Market is also
made up of stalls selling items. This IT system, FMMS, will enable the Council-manager to manage
information about the farmers market as well as the stalls.
It will be possible to inspect details for each stall separately. The details will include specifics of the stall as
well as specific details regarding discounts that may apply to certain items (e.g. All green apples might be
half price). Stalls will be.

Example products ( camcorder, dvd player, blueray player, tv, camera, xbox 360, ps4, Wii,
laptops, iphone, battery, smart phones, computer desktop, printer, usb, mouse)
Develop an inventory management system for an electronics store. The inventory system should
have the following functionalities:
BuildInventory: read a text file containing electronics products information and dynamically
store them in an array of pointers.
ShowInventory: display all inventory items.
UpdateInventory: ask for item id and quantity. If found display cost and update Product object
info (reduce Product's quantity and potentially update restocking flag).
Terminate: save current inventory to a text file.
This programming assignment illustrates the following concepts:
Text file reading and writing.
Arrays of pointers and dynamic memory allocations with new and delete.
Inheritance.
C++ type casting: static_cast.
NOTE: This assignment is not about polymorphism or dynamic_cast! Your program should not
contain any virtual function and/or use of dynamic_cast mechanism or point deductions will
apply. You will have opportunity to use polymorphism in the next assignment.
Class Design
You need at least three classes.
class InventoryItem (minimum implementation specified below) - This is the base class.
Protected member data: item id (integer) and restocking (bool).
Public static data:
const integer (item id): initialize to 9999.
const bool (restocking): initialize to false.
Constructors
Default constructor: initialize item id and restocking using the default static data with member
initializer syntax.
Non-default constructor: take 2 parameters.
Destructor: output "InventoryItem <item id> with <true/false> restocking destroyed ..."
Public member functions:
mutator/accessor for restocking, item id.
Display : to show InventoryItem item id and restocking (true/false). item id must be displayed as
a 4-digit integer with leading 0s if < 1000.
class Product : derived from InventoryItem class (minimum implementation specified below).
Private member data: name (string), quantity (integer) and price (double).
Public static data:
const string (name): "No Product".
const int (quantity): 0
const double (price): 0.99
Constructors (use member initializer syntax)
Default constructor: set member data to static data's default values above. Must explicitly invoke
the base class' default constructor.
Non-default constructor: take five parameters (id, restocking, name, quantity and price). Must
explicitly invoke the base class' non-default constructor.
Destructor: output "Product: <item id>, Name<name>, quantity<quantity>, price <price>,
restocking<true/false> destroyed ...".
Public member functions:
accessors/mutators for name, quantity, price.
Display: invoke Display from base class, then display its own data. NOTE: If the product
restocking is true somehow indicate it using "special effects" such as ***** or wh.

How does an open source operating system like Linux® affect Internet.pdfjyothimuppasani1
How does an open source operating system like Linux® affect Internet security and safety?
Solution
Since open source operating system\'s code is available to all,it\'s provides an easy access to
hackers and potential misusers which affects safety of such systems.
The non stable nature of Open source operating system also can be considered an important
factor that affects the Security.This is because Developers all over the globe modify the code and
thus the code is not stable and it becomes vulnerable to security threats.
Even if patches are introduced from time to time,mostly after an attack or so but due to large
flavours or distributions of open source software, some flavours are left without patches that
makes them vulnerable to attacks.
Also,The administration of open source operating system Servers also plays an important factor
in Internet Security. Since it is known that for example,Linux Server administration is more
difficult and when multiple ports are open it is sometimes not possible to handle an attack or
security threat immediately.
But then as it is said that every coin has two sides, Sometimes it is considered that Open Source
Systems like Linux are more secure because of the following reasons :.

Using
whatever Java IDE you prefer, create a project and add DList.java and DListTest.java to it (these
files are provided

occurrences of a specific
integer from the list. Here is the pseudocode:
Method removeAll(In: Integer pData) Returns Nothing
Define index variable i and initialize i to 0
While i < the size of this Dlist Do
If get(i) equals pData Then
remove(i)
Else
Increment i
End If
End While
End Method removeAll
Next, modify DListTest() to add test case 21 which tests that removeAll() works correctly.

VendingMachine, and VendingMachineDriver.
Problem Description
Milk,2.00,1
Within your VendingMachine class, include these methods:
VendingMachineThisconstructormethodwilltakeinthenameoftheinputfileand create a vending
machine object. A vending machine object will contain an array of Item objects called stock and
an amount of revenue earned. This constructor method has been completed for you and should
work appropriately once you have completed the rest of this class and the other class definitions.
vendThismethodwillsimulatethevendingtransactionafteravalidamountofmoney and an item
selection are entered. This method will decide if the transaction is successful (enough money or
item) and update the vending machine appropriately.
outputMessage This method will print an appropriate message depending on the success of the
transaction. If the user does not have enough money to buy the chosen item, the vending machine
should prompt the user to enter more money or exit the machine. If the vending machine is out of
the chosen item, the program will print an apology message and prompt the user to choose
another item or exit the machine. If there is enough money for the item selected, then the
vending machine will give the user the item and return the change.
printMenuThismethodprintsthemenuofitemsforthechosenvendingmachine. The Item class needs
to include the following data variables:
• description as a String
• price as a double
• quantity as an int
Within your VendingMachineDriver class, include a main method as the starting point for your
solution that creates the vending machine objects appropriately and then use a loop that
continues interacting with the vending machines until the user enters “X” to exit. See the sample
session for details.
As you implement your solution, you might find that some methods contain some repeated
coding logic. To avoid unnecessary redundancies in your code, have these method.
Esta charla comprende las lecciones aprendidas convirtiendo la app de Android de Teambox (una app repleta de deuda técnica y con un alto nivel de acoplamiento entre clases), en la versión actual de Redbooth, que intenta cumplir la arquitectura Hexagonal y los principios SOLID. Durante la exposición explicaremos como fuimos desenredando el código paso a paso; como aplicamos por partes los conceptos de la arquitectura hexagonal; como dejamos de lado componentes del framework de Android que dificultaban el mantenimiento de la app; y que errores cometimos, como los solucionamos y como se podrían haber evitado.

Assignment Overview:
This assignment requires you to complete various tasks involving classes you write with your partner. You
may also use classes that you find in the Java SDK.
The system that you will create is a Farmer’s Market Management System (FMMS). The FMMS is a tool
used by Dogwood Council to manage multiple Farmer’s Markets in their area. A Farmer’s Market may be
located at different sites, for different purposes (e.g. open-air market or indoor market, charity market,
community fundraising market, food swap market etc.) and different opening times.
Each Market has a name and is associated with a particular address and session time. Each Market is also
made up of stalls selling items. This IT system, FMMS, will enable the Council-manager to manage
information about the farmers market as well as the stalls.
It will be possible to inspect details for each stall separately. The details will include specifics of the stall as
well as specific details regarding discounts that may apply to certain items (e.g. All green apples might be
half price). Stalls will be.

laptops, iphone, battery, smart phones, computer desktop, printer, usb, mouse)
Develop an inventory management system for an electronics store. The inventory system should
have the following functionalities:
BuildInventory: read a text file containing electronics products information and dynamically
store them in an array of pointers.
ShowInventory: display all inventory items.
UpdateInventory: ask for item id and quantity. If found display cost and update Product object
info (reduce Product's quantity and potentially update restocking flag).
Terminate: save current inventory to a text file.
This programming assignment illustrates the following concepts:
Text file reading and writing.
Arrays of pointers and dynamic memory allocations with new and delete.
Inheritance.
C++ type casting: static_cast.
NOTE: This assignment is not about polymorphism or dynamic_cast! Your program should not
contain any virtual function and/or use of dynamic_cast mechanism or point deductions will
apply. You will have opportunity to use polymorphism in the next assignment.
Class Design
You need at least three classes.
class InventoryItem (minimum implementation specified below) - This is the base class.
Protected member data: item id (integer) and restocking (bool).
Public static data:
const integer (item id): initialize to 9999.
const bool (restocking): initialize to false.
Constructors
Default constructor: initialize item id and restocking using the default static data with member
initializer syntax.
Non-default constructor: take 2 parameters.
Destructor: output "InventoryItem <item id> with <true/false> restocking destroyed ..."
Public member functions:
mutator/accessor for restocking, item id.
Display : to show InventoryItem item id and restocking (true/false). item id must be displayed as
a 4-digit integer with leading 0s if < 1000.
class Product : derived from InventoryItem class (minimum implementation specified below).
Private member data: name (string), quantity (integer) and price (double).
Public static data:
const string (name): "No Product".
const int (quantity): 0
const double (price): 0.99
Constructors (use member initializer syntax)
Default constructor: set member data to static data's default values above. Must explicitly invoke
the base class' default constructor.
Non-default constructor: take five parameters (id, restocking, name, quantity and price). Must
explicitly invoke the base class' non-default constructor.
Destructor: output "Product: <item id>, Name<name>, quantity<quantity>, price <price>,
restocking<true/false> destroyed ...".
Public member functions:
accessors/mutators for name, quantity, price.
Display: invoke Display from base class, then display its own data. NOTE: If the product
restocking is true somehow indicate it using "special effects" such as ***** or wh.

How does an open source operating system like Linux® affect Internet.pdfjyothimuppasani1
How does an open source operating system like Linux® affect Internet security and safety?
Solution
Since open source operating system\'s code is available to all,it\'s provides an easy access to
hackers and potential misusers which affects safety of such systems.
The non stable nature of Open source operating system also can be considered an important
factor that affects the Security.This is because Developers all over the globe modify the code and
thus the code is not stable and it becomes vulnerable to security threats.
Even if patches are introduced from time to time,mostly after an attack or so but due to large
flavours or distributions of open source software, some flavours are left without patches that
makes them vulnerable to attacks.
Also,The administration of open source operating system Servers also plays an important factor
in Internet Security. Since it is known that for example,Linux Server administration is more
difficult and when multiple ports are open it is sometimes not possible to handle an attack or
security threat immediately.
But then as it is said that every coin has two sides, Sometimes it is considered that Open Source
Systems like Linux are more secure because of the following reasons :.

(Include your modified DList.java source code file in your homework solution zip archive)
Using
whatever Java IDE you prefer, create a project and add DList.java and DListTest.java to it (these
files are provided
in the Week 6 Source zip archive). Modify DList to implement a method that removes all
occurrences of a specific
integer from the list. Here is the pseudocode:
Method removeAll(In: Integer pData) Returns Nothing
Define index variable i and initialize i to 0
While i < the size of this Dlist Do
If get(i) equals pData Then
remove(i)
Else
Increment i
End If
End While
End Method removeAll
Next, modify DListTest() to add test case 21 which tests that removeAll() works correctly.

how can I replace the Newsfeed text with a custom on in SharePoi.pdfjyothimuppasani1
how can I replace the \"Newsfeed\" text with a custom on in SharePoint 365.
(Newsfeed Webpart)
Solution
First of all there are some differences between sharepoint and office 365. SharePoint has 4
versions still in active use : SharePoint 2007,2010,2016 and office 365. Office 365 released in
2011 With SharePoint2010 interface. Office 365 hav a various exclusive features like NextGen
Portals (Out of the box “ready to go” portals), Delve (A technology based on Office Graph that
presents “relevant information” to you based on your actions and interactions with colleague
files), Sway (A presentation web par that allows users to combine text, images and videos locally
and from the wider internet to create a usable website.), Yammer Integration (Yammer is the
enterprise social network that\'s being gradually rolled into all Office 365 features.) anf Office
365 Groups.
A custom CSS included in SharePoint master page in order to customize Newsfeed Web Part.
the code is:
.ms-microfeed-siteFeedTitleArea
{
background-color: silver;
padding-left: 20px;
text-transform:uppercase;
padding-bottom: 3px;
padding-top: 2px;
margin-bottom: 5px;

}
.ms-microfeed-postButtonSpan
{
margin-top: 2px;
}

}
Apart from this we can also hide controls, for this first we need to activate Site Feed feature, to
do this go to site settings->Manage Site Features and activate it
script for hide controls
I used the following CSS classes and its worked.

Did colonial rule freeze colonized societies by preserving old s.pdfjyothimuppasani1
Did colonial rule \"freeze\" colonized societies by preserving old social and economic patterns,
or was colonial rule a disruptive force of change?
Provide specific evidence to support each side of this question.
Solution
Transforming: Colonial rule gave African women greater autonomy in their day to day lives,
some of whom took advantage of trade.
New opportunities were also offered to cash crop farmers who were able to use colonial trade
networks for their own benefit.
Large scale conversion of some populations to Christianity
A minority got Western educations, which transformed their lives and their vision of their
society.
Preserving: No colonial society underwent Japanese-style industrialization.
Colonial societies engages mostly in primary economic activities, such as agriculture.
Colonialism stunted the growth of the middle class, creating unstable societies.
The practice of ruling through established authorities maintained the status quo..
Do you think that nonhuman animals have interests Does this mean th.pdfjyothimuppasani1
Do you think that nonhuman animals have interests? Does this mean that they also have rights?
Explain.
Solution
Human beings are living beings and so are the animals. A man is a known as a social animal only
because he has the ability to speak and interact in a more civilized way than any other animals.
But having said that, the rights surrounding to the human beings such as the ‘Right to live’,
remains the same even for the feral human beings who are such humans who are raised in the
Jungle and are isolated for some reason from the human world or contact. In this regard, if one
cannot distinguish a feral child, who can simply screech or crawl, rather than walk on two legs
and behave more like animals than like humans, from that of any other civilized human being,
then such a distinguished nature of human beings towards the nonhuman animals, is simply a
biased opinion. Animals are mute. They cannot speak for themselves. But they too have a heart
that throb like a human. They feel hunger. They feel the pain too. Even they long
companionship. They long for a community of their own to co-stay. Hence, I do believe
nonhuman animals do have interests. In such a case, they also have rights. They are simply
helpless because they are unable to reach us out in our ways. But that is not their fault. Perhaps
the rule of nature. The nature requires all to co-exist and hence the Noah’s ark once gave shelter
to creatures of all kind and not just restricted to the mankind. Even the nature wants the creatures
to live in harmony and that is possible when we do not invade their territory but of course, let not
them invade ours too. However, in today’s world, man’s greed has unturned the entire balanced
eco-cycle. We have deeply penetrated into the woods and concretized the Jungle to the extent
that we have quite literally done away with the interests of these nonhuman animals. For the
balanced eco-system, the contribution of the nonhuman animals have also been very significant.
But in a course of time, we snatched away their rights. Yes, we have laws in place to protect the
near-to-extinct animals or to stop killing or preying the nonhuman animals for organs selling and
other purposes. However, the illegal exploitation of these nonhuman animals have only helped us
think that perhaps the interests of the nonhumans or their rights are of much lesser importance
than that of the pleasure of the human beings for the only reason being that we, the humans can
speak and represent for ourselves. In the mask of civilization, we are rather heading to a more
sophisticated way of demeaning the rights of the animals or their interests..
Discuss the importance of recognizing and implementing different ent.pdfjyothimuppasani1
Discuss the importance of recognizing and implementing different entry strategies and
organizational arrangements which result in shared control and oversight through collaborative
relationships
Solution
Entry strategies are explained as a well planned method through which the company decide to
delivery its good and services to the targeted market.
The different types of market entry strategies and organizational arrangement and its importance
are discussed below:
1 .Exporting: when goods/Product are produced in one country and marketed in another country
then it is known as exporting.
2. Licensing: When a firm permit the company operating in another company to use its
manufacturing process, copyrights, and trademark with specific and determined payment.
3. Franchising: It’s an agreement between two companies, where a company (the franchiser)
gives all its rights to another company (the franchisee) to use its trademark, manufacturing
process and market to certain specification.
4. Joint venturing: In this two companies or investors share ownership and control over the
finance and operations of the firm.
5. Contract Manufacturing: In this the company operating in foreign countries gets into contract
to with the country operating there for manufacturing or assembling of the product.
6. Merger & Acquisitions: It is defined as restructuring of organization, for positive growth and
value. Merger means to ‘merge’ in which two companies legally merge into one into one entity,
whereas an acquisition means when one company takes over another and completely become
new owner.
All the entry strategies discussed above results in shared control through collaborative
relationships..

How would you reformulate the art center mission, has the center need a new strategy? why or
why not?
Solution
Anitha wants to bring some new innovation arts to the Arts center. This also brings more profit
for her. People who are crazy of arts expect more attractive and interesting arts,so she has to
increase her quality of arts to entertain the art lovers. Few people who don\'t have any knowledge
about arts also started trying out with arts. The art center mission can be reformulated by
inspiring them in participating in performances and they have to feel that what time they have
towards arts must be meaningful.
The strategy that can be used by sponsoring and contributing. This work can get help by adding
partners also. Through this they can teach others and also bring their talents out. By performing
like this the whole community gets attracted and her dream comes true. Through this they can
bring out the most hidden artists in the community and many artists are come out showing their
excellence in their art..

Conceptual skills are most important at the
Solution
Conceptual skills relate to the managers\' mental ability to coordinate and integrate all of the
organization\'s interests and activities. It is about thinking in the abstract and observing
relationships between forces that many others may not be able to see and to take a global
perspective of the organization and its environment. This is not so relevant at the lower level of
management and is most important at the top management level because the senior managers
must look for and exploit unseen opportunities for their organizations..

Solution
Database design
• Not easy!
• Will discuss formal methods next week
• Review: databases are made up of
– Tables: tables made up of
• Records: records made up of fields
• Speaking of rows and columns is misleading
• Critical issue: fixed number of fields, though a
specific field may be optional (aka not required)
– NOT NULL in MySQL jargon means required!
– MySQL does support variable length strings.
Data types
• Terminology varies for different DBMS
products
• Performance (speed) of operations varies
with different datatypes
• Size varies with different datatypes
• Performance and size limits are points of
competition among the different products
MySQL datatypes: numbers
• INT (aka INTEGER), can be UNSIGNED
(Size 4 bytes = 32 bits)
• TINYINT, SMALLINT, MEDIUMINT,
BIGINT
– Different sizes
• float (4 bytes), double (8 bytes), can
specify precision within these limits
• more
MySQL datatypes, strings
• CHAR(specified length)
• VARCHAR(maximum length)
• TINYBLOB short, variable length string,
up to 255 characters
• BLOB, TEXT variable length string
• MEDIUMBLOB, MEDIUMTEXT,
LONGBLOB, LONGTEXT
MySQL datatypes: enum
• ENUM
– Specify one of a set of values
– Stored as an integer, with 0 indicated unset or
not in the specified set
– Doing this may be more efficient because
built-in MySQL routines do the searching
MySQL datatypes: date/time
• DATE
• TIME
• DATETIME
• YEAR
• TIMESTAMP
Tables
• Specify one field as the primary key
• Primary keys are unique IN THAT TABLE
– Let the DBMS create the primary key OR
– Depend on intrinsic value that is guaranteed to be
unique
• Email addresses
• ISBN numbers
• ?
• A field in one table may be a foreign key. This is
a reference to a primary key in another table (or
this table). MORE ON THIS LATER.
Database
• Assume database itself is created for us
AND we have permissions to create new
tables.
• NOTE: permissions can be set by MySQL
commands, including queries sent by php.
• Start off talking general SQL and then
specific php and MySQL
Create table example
• CREATE TABLE movies (
mid INT NOT NULL AUTO_INCREMENT
PRIMARY KEY,
mname CHAR(30),
mdesc TEXT,
myear YEAR
)
Create table example
CREATE TABLE players (
pid INT NOT NULL AUTO_INCREMENT
PRIMARY KEY,
pname CHAR(30),
score INT NOT NULL,
lastplayed DATE
)
Create example
CREATE TABLE games (
gid INT NOT NULL AUTO_INCREMENT
PRIMARY KEY,
pid INT,
gtime TIMESTAMP,
score INT
)
The pid field will refer to / have the value of
the pid field (the primary key) of a specific
player. Here in this table, it is called a
foreign key.
Foreign keys
• Some versions of MySQL (and other DBMS)
have ways to specify the the pid value is a
foreign key
pid INT REFERENCE players
• The DBMS will check to make sure it is a valid
value.

write the To Dos to get the exact outputNOte A valid Fraction .pdfjyothimuppasani1
write the To Do\'s to get the exact output:
NOte: A valid Fraction number has a non-negative numerator and a positive denominator.
Default constructor initializes the object to safe empty state (an object with denom equals -1).
The two-argument constructor also validates the parameters and sets the object to the safe empty
state if the parameters are not valid.
Write the definitions and prototypes of following functions in Fraction.cpp and Fraction.h
respectively (They are indicated in the files by //TODO tag):
Define isEmpty function as a member function, which returns true if the object is in safe empty
state (an object is in the safe empty state if denominator (denom) equals -1).
Define display function, which sends a Fraction number to the output stream (with the
“Numerator/denominator” format). This function just prints \"Invalid Fraction Object!\" in the
screen if the object is in the safe empty state. In case that object denominator equals 1, it just
print the numerator.
Define the operator functions for the following operators:
“+=”, “+”, “*”
The overload of the above operators should make the following code possible:
The member operator+ : Adds two Fraction numbers and returns a Fraction number as the result.
This function returns an object with the safe empty state if either of Fraction numbers (operands)
is in safe empty state. It makes following code possible:
A+B ( where A and B are Fraction objects)
The member operator+= : Adds two Fraction numbers and assigns the result to the left operand,
then returns a reference to the left operand. If either of Fraction numbers (operands) is in safe
empty state, it initializes the left operand to the safe empty state, then returns a reference to the
left operand. It makes following code possible:
A+=B ( where A and B are Fraction objects)
The member operator* : Multiplies two Fraction numbers and returns a Fraction number as the
result. This function returns an object with the safe empty state if either of Fraction numbers
(operands) is in safe empty state. It makes following code possible:
A*B ( where A and B are Fraction objects)
fraction.cpp
#include \"Fraction.h\"
using namespace std;

Fraction::Fraction(){
denom =-1; // safe empty state

What are the factors that contribute to H+ gain or loss How do lung.pdfjyothimuppasani1
What are the factors that contribute to H+ gain or loss? How do lungs and the kidneys balance or
regulate the changes in pH?
Solution
Answer=
Factors that contribute to loss or gain of H ions are=
CO2 concentration
O2 concentration
bicarbonate concentration in urine
The lungs regulate the changes in PH = Acid base imbalances in the bloods pH can be altered by
changes in breathing to expel ,ore CO2 & raise the pH back to normal
Hydrogen ions are carried in the blood along with oxygen & carbon dioxide
60 % CO2 is carried as a dissolved bicarbonate
A small amount of CO2 is carried on Haemoglobin as carbaminohaemoglobin which is
transported to the lungs for removal
Acid base imbalances that overcome the buffer system can be compensated in the short term by
changing the rate of ventilation
When pH of blood drops too low ,the body compensates by increasing breathing to expel more
CO2 & during alkalemia the inspiration occurs
Regulation of pH by kidneys =
kidneys have 2 important roles in maintaining the acid -base balance
1]They reabsorb bicarbonate from urine
2] they excrete hydrogen ions into urine
The major homeostatic control point for maintaining a stable pH balance is renal excretion
Bicarbonate does not have transporter ,so its reabsorption involves a series of reactions in the
tubule lumen & tubular epithelium .
In response tyo acidosis the tubular cells reabsorb more bicarbonate from the tubular fluid ,& the
collecting cells secrete more hydrogen & generate more bicarbonate
In response to alkalosis ,the kidneys may excrete more bicarbonate by decreasing Hydrogen ion
secretion from tubular epithelial cells ,& lowering the rates of glutamine metabolism &
ammonium excretion.
Write down the four (4) nonlinear regression models covered in class,.pdfjyothimuppasani1
Write down the four (4) nonlinear regression models covered in class, i.e. both the name of the
model and their functional form showing their respective regression coefficients. A rapidly
growing bacteria has been discovered with a growth rate as shown in the table. Analyze this date
using a power law model. First linearize the data in the table based on the power law model, call
this new linearized data x and y. Next, determine the coefficients a_0 and a_1 of a linear
regression y = a_0 + a_1x for the linearized power law data x and y, and compute the correlation
coefficient for the liner regression. Note that you are not being asked to do a linear regression of
the data in the table but rather a linear regression of the linearized version of that data. Once you
compute a_0 and a_1 use these to determine the coefficients of the power law model. Write a
Matlab script that uses the polyfit function to determine the regression coefficients of a second
order polynomial fit to data in the table. In the same script, write down the code for using the
polyval command to determine the value of the regression curve at the observed times.
Solution
Nonlinear regression is a statistical technique that helps describe nonlinear relationships in
experimental data. A nonlinear regression model can be written Yn = f(xn, ) + Zn where f is the
expectation function and xn is a vector of associated regressor variables or independent variables
for the nth case.
A nonlinear model is one in which at least one of the parameters appears nonlinearly. More
formally, in a nonlinear model, at least one derivative with respect to a parameter should involve
that parameter. Examples of a nonlinear model are:
Y(t) = exp(at+bt2)
Y(t) = at + exp(-bt).
Important non linear growth models
1.Logistic Model
This model is represented by the differential equation
dN/dt = rN (1-N/K).
Integrating, we get
N(t) = K / [1+(K/No-1) exp(-rt)]
The graph of N(t) versus t is elongated S-shaped and the curve is symmetrical about its point of
inflexion.
2.Malthus Model
If N(t) denotes the population size or biomass at time t and r is the intrinsic growth rate, then the
rate of growth of population size is given by
dN/dt = rN.
Integrating, we get
N(t) = No exp (rt),
where No denotes the population size at t=0. Thus this law entails an exponential increase for
r>0. Furthermore, N(t) à as t à , which cannot happen in reality.
3. Monomolecular Model
This model describes the progress of a growth situation in which it is believed that the rate of
growth at any time is proportional to the resources yet to be achieved, i.e.
dN/dt = r(K-N),
where K is the carrying size of the system. Integrating (3.3), we get
N(t) = K-(K-No) exp (-rt).
4. Richards Model.
This model is given by dN/dt = rN (KN – Nm)/mKm which, on integration, gives N(t )=K N0 /[
N0+ (KN – N0m) exp (-rt)]1/m.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
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.
