Develop a program to maintain a list of homework assignments. When an assignment is assigned, add it to the list, and when it is completed, remove it. You should keep track of the due date. Your program should provide the following services: 1. Add a new assignment. 2. Remove an assignment. 3. Provide a list of the assignments in the order they were assigned. 4. Find the assignment(s) with the earliest due date.

In java , I want you to implement a Data Structure known as a Doubly-Ended-Queue. it is a “fair” data structure in that it implements a FIFO (First In First Out ) behavior. As such, it is often used to implement various wait lists in computer systems. For example, jobs waiting to use the CPU, jobs waiting for a printer, jobs waiting to be placed into RAM for execution. In short, whenever we want a fair strategy for waiting we use queues. A DEQUE (Doubly-ended-queue) is a related data structure. Although similar to a Queue, it differs in that it allows for insertions AND deletions from either end of the list (both the front and the rear). Your implementation MUST use a doubly-linked-list implementation. You may not use a static array implementation. Thus, a Deque is a List but it is one which only concerns itself with the first and last positions for any insertion or deletion. The 6 operations supported are : public void insertFront( int item ) - insert the given item (as a node) into the first position of the Deque. public void insertRear( int item ) - insert the given item (as a node) into the last position of the Deque. public int deleteFront( ) - delete and return the element stored in the first node of the Deque. public int deletRear( ) – delete and return the element stored in the last node of the Deque. public boolean isempty( ) - returns true if the Deque is currently empty or false if it is not. public void printDeque( ) - print the integers from the list, one per line, from the first element through to the last in order. Classes Your program must implement the following 3 classes. public class dequeDriver This class will contain your program’s main method. It will need to declare a deque object and process input as indicated below. Your program should prompt the user for the path of an input file. It should open the file for input and process it line by line. Each line of the input file will have one of the following forms. PR IF IR DF DR The meanings of each input is as follows: PR - print the current contents of the deque from front to rear using the printDeque( ) method of the deque object. IF - insert the given int value into the front of the deque. IR - insert the given int value into the rear of the deque. DF - delete the front value from the deque. DR – delete the rear element of the deque. Below is an example input file that your program should be able to process. PR IF 4 IF 5 IF 6 IR 7 PR DR PR DF PR The output for the input file shown above is : EMPTY DEQUE ----- Front ----- 6 5 4 7 ----- Rear ----- ----- Front ----- 6 5 4 ----- Rear ----- ----- Front ----- 5 4 ----- Rear ----- public class dequeNode This class will implement the linked nodes that will be used to implement the deque itself. It should have the following protected data members. protected dequeNode next; // next pointer to next node protected dequeNode prev; // previous pointer to previous node protected int val; // the integer value stored within the dequeNod.

Introduction and Background In recent lectures we discussed using arrays, classes and interfaces (see newly added course notes if you want to read ahead about interfaces – we will cover them this week in lecture). In this lab you will utilize all of these topics to build a simple yet useful new class. Consider the following interface describing the methods for a simple double ended queue (or deque): public interface SimpleDeque { public void addFront(Object X); // Add Object X at front of list public void addRear(Object X); // Add Object X at rear of list // If array is full, add methods should do nothing public Object removeFront(); // Remove and return Object X from // front of list public Object removeRear(); // Remove and return Object X from // rear of list // If array is empty, remove methods should return null public boolean isEmpty(); // Return true if the list is empty // Return false otherwise } A queue has the behavior such that items are added at the rear and removed from the front, thereby giving a First In First Out (FIFO) access to the items added and subsequently removed from the list. No other manipulations of the data are permitted (for example, we cannot add or remove anywhere in the middle). Looking at it \"in reverse\", we could add new items at the front of the queue and remove them from the rear. This is still providing FIFO access, but just from a different point of view. Now consider both adding and removing items at the rear of the list (without ever accessing the front). This is called stack access and gives us Last In First Out (LIFO) access to the items (the data is removed in reverse order). The same behavior occurs if we both add and remove at the front without ever accessing the rear of the list. The simple deque above is expressed as an interface rather than a class, because we are not describing the data or how it is represented -- we are simply describing its access behavior. However, to actually build a working deque, we need a class that implements the interface above. For example: public class MyDeque implements SimpleDeque { Object [] theData; int numItems; public MyDeque(int maxItems) { theData = new Object[maxItems]; numItems = 0; } // Implementation of the five methods of SimpleDeque, plus // perhaps other methods as well } Note that the implementation above uses an array of Object to store the items in the deque. Since Object is the base class to all other Java classes, an array of Object can thus be used to store any Java class types (we can even store primitive values if we utilize their wrapper classes). Also note that nothing in the SimpleDeque interface requires an array to be used to store the data. You will see in your CS 0445 course that a linked list may in fact be a better implementation than an array in this case. However, for this implementation we will use an array because it is simple and easy to understand. Another important thing to notice about the partial implementation above is tha.

Why are standards needed in data communication and networking? What are the advantages and disadvantages of standards? How do standards fit in with regulations at the federal, manufacturing, and organizational levels? Give an example of a standard that fits in at your workplace. Solution he Importance of Standards Standards are necessary in almost every business and public service entity. For example, before 1904, fire hose couplings in the United States were not standard, which meant a fire department in one community could not help in another community. The transmission of electric current was not standardized until the end of the nineteenth century, so customers had to choose between Thomas Edison’s direct current (DC) and George Westinghouse’s alternating current (AC). The primary reason for standards is to ensure that hardware and software produced by different vendors can work together. Without networking standards, it would be difficult—if not impossible—to develop networks that easily share information. Standards also mean that customers are not locked into one vendor. They can buy hardware and software from any vendor whose equipment meets the standard. In this way, standards help to promote more competition and hold down prices. The use of standards makes it much easier to develop software and hardware that link different networks because software and hardware can be developed one layer at a time. The Standards-Making Process There are two types of standards: formal and de facto. A formal standard is developed by an official industry or government body. For example, there are formal standards for applications such as Web browsers (e.g., HTTP, HTML), for network layer software (e.g., IP), data link layer software (e.g., Ethernet IEEE 802.3), and for physical hardware (e.g., V.90 modems). Formal standards typically take several years to develop, during which time technology changes, making them less useful. De facto standards are those that emerge in the marketplace and are supported by several vendors but have no official standing. For example, Microsoft Windows is a product of one company and has not been formally recognized by any standards organization, yet it is a de facto standard. In the communications industry, de facto standards often become formal standards once they have been widely accepted. The formal standardization process has three stages: specification, identification of choices, and acceptance. The specification stage consists of developing a nomenclature and identifying the problems to be addressed. In the identification of choices stage, those working on the standard identify the various solutions and choose the optimum solution from among the alternatives. Acceptance, which is the most difficult stage, consists of defining the solution and getting recognized industry leaders to agree on a single, uniform solution. As with many other organizational processes that have the potential to influence the sales of hardwar.

Which of the following statements about human evolution is correct? A) The upright posture and enlarged brain of humans evolved simultaneously. B) Fossil evidence indicates that early anthropoids were arboreal, were cat-sized, and lived about 35-45 million years ago. C) Human ancestors were virtually identical to chimpanzees. D) Human evolution occurred by anagenic change within an unbranched lineage. E) Modern humans are the only human species to have evolved on Earth. Please explain reasoning. Thank you. Solution B.Fossil evidence indicates that early anthropoids were arboreal, were cat-sized, and lived about 35-45 million years ago. Reason:-The fossil record of Family Felidae extends to the Late Eocene, 34 million years ago.The first known feline was Aelurogale. Its descendent, Proailurus, gave rise to the major branches of the cat family we see today.Miacoid species gave rise to Proailurus which appeared about 30 million years ago, and is generally considered the first true cat.There were other cat-like species before Proailurus.Archeological evidence shows a relationship between man and cat for the past 8,000 years..

This is question about excel cuers wish to answer shortly how to use. How would you use Financial Functions, Data tables and Hyperlinks on a day-to-day functions? Solution Excel provides an enormous number of functions to analyze, audit and calculate data. Some of them are utilized by many Excel users on a daily basis while others are so very specific that only a small group of financial, statistical or engineering specialists understand and need them. financial functions ******************* Excel has a wide assortment of financial functions that are used by thousands of financial analysts every day. Microsoft Excel provides a host of functions to simplify the work of accounting managers, financial analysts and banking specialists. Here are some commonly used financial functions in Excel they are i)Present Value (PV) = the value of the load or savings today. ii)Interest Rate per period (RATE) = the interest rate, usually monthly (if given an annual rate, be sure to divide by 12!) iii)Number of payment periods (NPER) = Number of payment periods (number of months usually). iv)Periodic payment (PMT) = The payment per period (monthly payment usually). This value is the same for every payment period. Data tables *********** A data table is a range of cells in which you can change values in some in some of the cells and come up with different answers to a problem. You can create one-variable or two-variable data tables, depending on the number of variables and formulas that you want to test. You can find some cool uses for tables in your data to day work. They are intuitive, easy to use and provide great power without added complexity. Hyperlinks ********** A Hyperlink is nothing but a reference to a document, a location or an action that the reader can directly follow by selecting the link. Excel provides a convenient way for linking up cells data with whatever you want. To create hyperlinks in the sheet. Select the cell in which you want to create hyperlink and right- click to select Hyperlink. When you click the cell that contains the HYPERLINK function, Microsoft Excel opens the file that is stored at link_location. The use of Hyperlinks in Excel has been extended to a number of areas and this includes: Opening Files (of any type) Opening Web Pages (Internet or Intranet).

There is a requirement to design a system to sense the presence of glass bottles leaving an automatic washer on a production line conveyor belt. The production line is for food products and the environment is clean and maintained at a temperature of 15 degree C. The system must meet the following criteria: The switching distance will lie between 5 and 20 mm. The output from the sensor is to be of binary form, i.e. logical 1 when the part is present and logical 0 when no part is present. It is necessary to ensure that a change of sensor state occurs closer to the sensor when a bottle approaches than when it moves away. Bottles will pass the sensor at the rate of 10 every second. There is no requirement for protection from contact with objects but it must be proof against water drips. Recommend a suitable sensor and justify your recommendation. Sketch a diagram that shows the functional blocks within the sensor and explain each function. Solution lock Diagram of the system Basic Elements Used MICRO CONTROLLER RESISTORS CAPACITOR INDUCTOR POWER DIODE WATER PUMP IR SENSORS DC MOTOR CONVEYOR BELT Resistore A part from resister and inductor, a capacitor is the other basic component used in electronic circuits. It is a device which 1. Has the ability to store charge which neither a resistor nor an inductor can do; 2. opposes any change of voltage in the circuit in which it is connected; 3. Blocks the passage of direct current through it. CAPACITOR The electronic component (mostly a coil) which opposes the change of current in circuit is called an inductor. The ability of coil or inductor due to which it opposes the change of current flowing through it is known as its inductance. The inductance of an inductor may also be defined as the ability of an inductor to produce induced voltage when the current varies through it. The unit of inductance is Henry which is named after Joseph Henry. INDUCTOR Diodes allow electricity to flow in only one direction. The arrow of the circuit symbol shows the direction in which the current can flow. Diodes are the electrical version of a valve and early diodes were actually called valves. The construction and the fundamental working of the power diode and signal diode are same but the power handling capacity of the power diode is higher than the signal diodes POWER DIODE Sensors IR Sensors work by using a specific light sensor to detect a select light wavelength in the Infra- Red (IR) spectrum. By using an LED which produces light at the same wavelength as what the sensor is looking for, you can look at the intensity of the received light. When an object is close to the sensor, the light from the LED bounces off the object and into the light sensor. This results in a large jump in the intensity, which can be detected using a threshold DRIVER CIRCUIT FOR DC MOTOR We have used the dc motors to drive conveyer belt and to. The driver circuit for dc motors is shown below. COMPARATOR CIRCUIT Comparator circuit is used in thi.

Research and explain the deviant actions of the Los Angeles Police Department’s Rampart CRASH unit during the late 1990s. Did socialization and culture of the unit have a role within the officer’s deviant behaviors? As a member of the CRASH team, what would have been your course of action after observing the illegal conduct? submit your answer in 3-5 pages. Solution Traditional definitions of police misconduct, especially Apolice corruption,@ are imprecise. In the past, police scholars have classified acts of police misconduct as Apolice corruption,@ Apolice brutality,@ and Adrug-related misconduct.@ We found, however, that these classifications are not mutually exclusive, and that determining whether profit-motivated criminality by police officers involved jobrelated police corruption frequently is impossible. - Involuntary separations are rare. Separations for cause from the New York City Police Department (through dismissals, terminations, and forced resignations and retirements) are infrequent events. Only two percent of the officers employed by the NYPD during the 22 years (1975-96) we studied were involuntarily separated from the department. - Pre-employment history matters. Officers whose life histories include records of arrest, traffic violations, and failure in other jobs are more likely than other officers to be involuntarily separated from the NYPD. - Education and training matter. Officers who hold associate or higher degrees are less likely than those who do not to be involuntarily separated. Those who do well in the Police Academy=s recruit training program are less likely than marginal recruits to be separated as unsatisfactory probationers. Subsequently, they also are less likely to be involuntarily separated for cause after successful completion of their probationary periods. - Diversity matters. As the NYPD has become more diverse, it has become better behaved. We found a very strong inverse correlation (r=-.71; r2 .50) between the percentage of white male NYPD officers and the department=s annual rate of involuntary separations. - Race still matters, but apparently only for black officers: As the representation of Hispanic and Asian officers in the NYPD has increased, their involuntary separation rates have decreased and become virtually indistinguishable from those of white officers. Black officers= representation in the NYPD remained relatively flat during the years studied. Black officers= involuntary separation rates have also decreased, but remain higher than those for other racial groups. This document is a research report submitted to the U.S. Department of Justice. This report has not been published by the Department. Opinions or points of view expressed are those of the author(s) and do not necessarily reflect the official position or policies of the U.S. Department of Justice.

Please revise the answer bellow. Q1. What historically have been Apple’s competitive advantages? There have been many competitive advantages that have allowed Apple to be a consistent leader in the PC market. One competitive advantage has been their innovative spirit. This was shown with the initial release of the Apple 2. Steve Job’s mission of Apple was to bring an easy-to-use computer to the market, and this is what he accomplished with the release of the Apple 2. The Apple 2 was a revolutionary product that changed the PC world forever. The Apple 2 was launched in 1978 and it lead the PC industry to $1 billion in annual sales in less than three years. Another competitive advantage for Apple is that they have total control over all of the software, hardware, and operations related to Apple products. The apple software is horizontally and vertically integrated, meaning it relies on its own designs and does not license software to third parties. Apple released the Mac in 1984, which featured an interface that was easy-to-use, a great industrial design, and technical proficiency. The superior software allowed Apple to enter the Mac into new markets, desktop publishing and education. In education, Apple grabbed almost half of the market and by 1990, Apple had $1 billion in cash and was the most profitable PC Company in the world. Furthermore, Apple hired Tim Cook to streamline the Apple supply chain, and also Apple launched a website to set up direct sales. This has allowed Apple to be successful by creating a comprehensive, unified culture with all aspects of the company. Their most important competitive advantage was Steve Jobs. Being the co-founder, Steve Jobs had the long-term vision of Apple and worked every day to live out the vision. Steve Jobs was forced out of 1985, but returned as the interim CEO in 1997 when the company was near bankruptcy. Jobs refocused Apple to only having 4 product categories, rather than 15 it had previously. Through Steve Job’s leadership, Apple created the iMac in 1998, which allowed Apple’s sales to outpace the industry average for the first time in many years. Steve Jobs made strategic decisions to make Apple products the most competitive by bringing a new culture to Apple, and positively changing the image and brand of Apple. Q2. Analyze the personal computer industry. Why did Apple struggle historically in PCs? It is true that Apple was the company who pioneered the personal computing devices, but IBM was the company the mainstream PC’s. This was the biggest competitor to the early success of Apple. The IBM PC operated on an “open” system that allowed producers to clone it. Another reason why Apple struggled with PCs was the price. Macintosh did have a loyal customer base which allowed them to sell it at a premium price. IBM- compatible prices started to drop, and the high Macintosh’s looked unfeasible and too expensive. Another reason for the struggle of Apple PCs was the rise of “Wintel”. “Wintel” was t.

Negligence Curtis R. Wilhelm owned beehives and kept the hives on property he owned. John Black, who operated a honeybee business, contracted to purchase some beehives from Wilhelm. Black employed Santos Flores, Sr. to help him pick up the beehives from 101102Wilhelm. Black provided Flores with a protective suit to wear while picking up the beehives. Neither Wilhelm nor Black informed Flores of the danger of working with bees. After picking up beehives from Wilhelm’s home, Black and Flores drove to remote property owned by Wilhelm to pick up other beehives. Flores opened the veil on his protective suit. After loading one beehive onto the truck, Flores started staggering and yelling for help. Flores sustained several bee stings, suffered anaphylactic shock reaction, and died before an ambulance could reach him. Flores’s wife and children sued Wilhelm and Black for negligence for failing to warn Flores of the dangers of working with beehives and the possibility of dying of anaphylactic shock if stung by a bee. Did Wilhelm act negligently by failing to warn Flores of the dangers of working with beehives? Wilhelm v. Flores, 133 S.W.3d 726, Web 2003 Tex. App. Lexis 9335 (Court of Appeals of Texas) Solution Answer: Yes. The Court of Appeals held that the owner of the bees owed a duty to warn Flores of thedangers of working with bees and bee stings, affirming the award of damages..

Introduction to Database Management System: Consider the following relation of students: R(A, B, C, D, E, F, G) (A is underlined) D is a candidate key. Suppose the following dependencies exist: FD1: A-> B, C, D, E, F, G FD2: C, D -> A, B, E, F, G FD3: D-> G FD4: F -> C Apply normalization until you cannot decompose the relations further. State the reasons behind each decomposition. Solution FD1: A-> B, C, D, E, F, G: This Functional dependency uniquely idendifies the table row so, all other functional dependecies are not need. we simply ignore all other. >>> for example it any of the FD voilates any of the NF then we will decompose it and create a new table for that FD. Here FD2 voilates 3NF but if we want to decompose it what could be the foreign key in R2 since all other attributes are present in relation R1:(A, B, C, D, E, F, G) . >>>Therefore FD1 is the final one for the Relation..

In BC’s nearly-decade-old “new” curriculum, the curricular competencies describe the processes that students are expected to develop in areas of learning such as mathematics. They reflect the “Do” in the “Know-Do-Understand” model. Under the “Communicating” header falls the curricular competency “Explain and justify mathematical ideas and decisions.” Note that it contains two processes: “Explain mathematical ideas” and “Justify mathematical decisions.” I have broken it down into its separate parts in order to understand--or reveal--its meaning. The first part is commonplace in classrooms. By now, BC math teachers—and students—understand that “Explain mathematical ideas” means more than “Show your work.” Teachers consistently ask “What did you do?” and “How do you know?” This process is about retelling, not just of steps but of thinking. The second part happens less frequently. Think back to the last time that you observed a student make—a necessary precursor to justify—a mathematical decision. “Justify” is about defending. Like “explain,” it involves reasoning; unlike “explain,” it also involves opinion and debate. In order to reinterpret the curricular competency “Explain and justify mathematical ideas and decisions,” I will continue to take apart its constituent part “Justify mathematical decisions” and carefully examine the term “mathematical decisions.” What, exactly, is a “mathematical decision”? Below, I will categorize answers to this question. These categories, and the provided examples, may help to suggest new opportunities for students to justify.
