...be exact, of all American adults have a smartphone (Mobile Technology Fact Sheet, 2014). One of the biggest draws to a smartphone is the ability to download and use mobile applications. Because of the widespread adoption of mobile communicating devices, the demand for creating new ways to develop exciting, fun and innovative mobile applications is prominent. Apple Inc., a global electronics juggernaut, has been one of the leading pioneers of this groundbreaking new forefront. In the fall of 2014, Apple introduced a new programming language for their mobile operating system, iOS. Swift combines the best of Apple’s previous language “C” with safe programming patterns and modern features (The Swift Programming Language, n.d.). Swift is known for being the most modern, safe, fast and powerful programming language that is available for the iOS operating system. With the decades of experience at Apple, the have created the most modern and relevant programming language on the market. It was created to make the code used to develop apps easier to read and maintain. Because of this easier way of writing code, programmers are less apt to make mistakes which will lead to less bugs and glitches in applications (Introducing Swift, n.d.). The revolutionary language was designed to be the safest language ever. “Variables are always initialized before use, arrays and integers are checked for overflow, and memory is managed automatically.” (Introducing Swift, n.d.) Using Swift, one character...

...Values of the decision variables must be chosen such that the inequality constraints are all satisfied while either maximizing or minimizing the desired performance variable. These models can contain tens, hundreds, or thousands of decision variables and constraints. Linear Optimization Very efficient search techniques exist to optimize constrained linear models. constrained These models are historically called linear programs linear (LP). In this chapter we will: 1. Develop techniques for formulating LP models 2. Give some recommended rules for expressing LP models in a spreadsheet that facilitates application of Excel’s Solver 3. Use Solver to optimize spreadsheet LP models Formulating LP Models Every linear programming model has two important features: Objective Function Constraints A single performance measure to be maximized or minimized (e.g., maximize profit, minimize cost) Constraints are limitations or requirements on the set of allowable decisions. Constraints may be further classified into physical, economic, or policy limitations or requirements. Formulating LP Models The first step in model formulation is the development of the constraints. For example: Investment decisions are restricted by the amount of capital and government regulations. Management decisions are restricted by plant capacity and availability of resources. Staffing and flight plans of an airline are restricted by the maintenance needs of...

...This part of the project is all about planning the overall project. As instructed, a Visual Logic flowchart was designed, as well as a pseudo code for the project. As in most cases, these things are living plans, meaning that they are not written in concrete. As the need arrives, the code and flowchart can be modified to better fit the desired outcome. The pseudo code consists of three string variables, five number variables, three arrays, and a Boolean variable. The string variables are mainly for the use of storing data which will be used for searching the arrays or for storing new types of information in the array. The number variables are being used mainly for the option of making choices. This program has a few choices where the user can go one of two ways. For example, in the beginning, they can choose whether they would like to add new data or view already stored data. That will be determined by the variable “choice1”. The variable “choice2” will allow for the user to make a choice depending on the choice they made for “choice1”. The last choice variable , “choice3”, is used only to allow the user to determine whether they are done using the program or not. A very important variable called “count” will store the number of data entries the user has inputted. This will come in handy when traversing the arrays. The variable “i” is only used for use in the For loops and referencing the array. There are three arrays in the program. The “informationGenre[]”...

...Programming Solution Proposal Donald L. Smith PRG/211 June 24, 2013 Jack Warner Programming Solution Proposal The McBride Financial Services Company, a part of the Virtual Organizations, needs a computer program to calculate mortgage payments in their agent field offices. The agents want to input a mortgage loan amount, an interest rate, and a number to pay off the loan into this program and have the mortgage’s monthly payments as output. In addition, agents want the program to calculate the pay-off amount of the loan for a specific year(s) or an amortization table for the mortgage. The benefits of this program are faster and more reliable than using manual calculations or an electronic calculator where they can still key in the wrong number. The program can also be ported to a company website. This website can be accessed by customers to inquire about mortgage information and thus free the agents’ time for such requests. The program development cycle is the best approach for coding a program solution. The first paragraph has done the analyzing of the problem, then comes the design phase. The requirements for this task are identified as input, output, and processing tasks. Tasks are coded into a program module. This breaking down of tasks into modules is known as modular programming. According to Torres (2012), ”Breaking down a programming project into modules makes it more manageable. These individual modules are easier to design, implement, and test. Then...

...REVISED SIMPLEX METHOD We have implemented the simplex algorithm by using the Tableau to update the information we proceed along the various steps. For problems with only a few variables the simplex method is efficient. However, problems of practical interest often have several hundred variables. The tableau method is hopeless for problems containing more than a few variables. We are in fact calculating AB-1aj for all j as well as calculating all components of the relative cost coefficient r, albeit in an fairly automatic manner. However, we really need to know only one component rj of r, one row AB-1aj of the Tableau †(B), and the column constant AB-1b of the Tableau in order to pass to the next basic index set B. The goal of the revised simplex method is the ordering of all calculations so that no unnecessary calculations are performed. No new theory will be need. The simplex algorithm exactly as written in an earlier chapter will be implemented. The implementation will avoid all unnecessary calculations and will try whenever possible to update any available information. The Simpex Algorithm (Theoretical Foundation) 1. 2. Start with some basic index set B1 = {i(1), i(2), … ,i(m)}. Compute a coefficient of the relative cost coefficient rj = cj - cBAB-1aj for B1 until some index j with rj > 0 is found. (i).If all rj ≤ 0, termination phase has been reached. (ii).Only those j M N1 are candidates 3. Find AB-1aj = aj and AB-1b = b and compute the allowable ratios of the jth column...

...Michael Ayala 5/12/12 Psych 1 Assessment 1 Essay In the the first example, the researcher used the experimental design in his study to examine how poeple respond to pictures of faces with different racial features. The experimental design is when the experimenter isolates and controls all the variables excpet one, he makes sure that variable is the only one causing the desired effect. The The independent variable, which is the variable that the researcher is manipulating, is computer program that he created that will randomly generate the faces as each subject comes in. In this study the researcher used random assignment as the the subject would come in the the room. Random assignment is went the experimental and control groups a non-systematic and randomized way. The way he did this is by not telling his research nor the subjects knew which order they were going in. The team of researchers that found that the more time students spend interacting with technology, the less empathy they show towards other by doing a correlation study. Since many students already use technology a lot this was would be easier to use. The students increased use of their devices is one variable and their lower empathy towards other is the second one making a negative correlation. A negative correlation is a correlation indicating that the variables simultaneous in opposite directions. The second researcher...

...Operations Research and its Prospects in Pakistan Prof. Dr. Shoaib ud Din Mathematics Department Punjab University, Lahore, Pakistan Operations Research has had an increasingly great impact on the management of organizations in the recent years. In fact, with the exception of advent of electronic computer, the extent of this impact seems to be unrivalled by that of any other recent development. However, all the development in this field has gone almost unnoticed in most developing countries including Pakistan. This article is an effort to introduce Mathematics community in the country to the subject and its achievements. A brief history In order to appreciate the importance of OR in the world today it is important that we know something of its history and evolution. Although roots of Operations Research can be traced back many decades, it is generally agreed that this discipline began during World War II. During the War team of British scientists with diverse background were called upon to study the strategic and tactical problems associated with air and land defense of the country. The establishment of this scientific team marked the first formal Operations Research activity. Their efforts were allegedly instrumental in winning the Air Battle of Britain, The Island Campaign in the Pacific, the Battle of the North Atlantic, and so on. The name Operations Research-Operational Research in the United Kingdom – was apparently coined because the problems assigned to this team...

...language—essentially, a "switchon/switchoff" pattern. Today, using tiny electronic switching mechanisms inside the computer, "decisions" are made with lightning speed within the central processing unit (CPU). These decisions are based on whether a tiny switch is on or off at any given time. Computer programmers follow prescribed sets of instructions to "teach" computers how to make decisions to carry out instructions. Programming is made possible by sets of instructions called languages. Many of these languages are made up of the logic building blocks identified by Mr. Boole more than 100 years ago, long before computers. The building blocks that Mr. Boole identified are AND logic, OR logic, NOT logic, NAND logic, and NOR logic. Computer decisions are made from these patterns of logic. All programming languages allow you to create expressions that can be evaluated as either true or false, which are called Boolean expressions. A Boolean condition is a conditional statement containing a Boolean expression, and another name for a conditional statement is a hypothesis. In computer programming languages, a hypothesis is formed by using the word “if” with a Boolean expression. The Boolean expression can be evaluated as True or False. When the Boolean expression within the hypothesis is true, then the conclusion occurs. The conclusion will not happen unless this hypothesis is satisfied as True. So, the “if” statement uses the...
