...Programming Solutions Being able to create a solution to a certain problem through programming can be a huge task to undertake, but it is a task that must be accomplished in order to get certain things done. Many companies face problems in the IT field that can be solved through programming, from simple to very complex, these problems usually require some sort of input and variables in order to create a solution. One problem that I face in the workplace of construction, is trying to figure out the number of ceiling tiles we will need to fit the ceilings in most offices we build. The ceiling tiles are a certain size and cover large areas which can be a tedious task trying to count how many tiles it will take to fill in the ceiling. A programming solution could be very beneficial in an instance such as this because by creating inputs such as the size of the tiles and the area they need to cover, an output could be the number of tiles that will be needed and thus saving a large amount of time on counting every space they need to fill. This problem of having to determine the number of ceiling tiles it will take to cover the celling area is normally done by counting the spaces in the ceiling that need to be filled and then determining how many tiles will need to be purchased. By coming up with a program to solve this problem would no doubt save a lot of time and even money by not buying an excess amount and either throwing them away or storing them. I believe a simple program would...

...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...

...Instructor’s Solutions Manual to Concepts of Programming Languages Tenth Edition R.W. Sebesta ©2013 Pearson Education, Inc. Upper Saddle River, NJ. All Rights Reserved. Preface Changes for the Tenth Edition T he goals, overall structure, and approach of this tenth edition of Concepts of Programming Languages remain the same as those of the nine earlier editions. The principal goals are to introduce the main constructs of contemporary programming languages and to provide the reader with the tools necessary for the critical evaluation of existing and future programming languages. A secondary goal is to prepare the reader for the study of compiler design, by providing an indepth discussion of programming language structures, presenting a formal method of describing syntax and introducing approaches to lexical and syntatic analysis. The tenth edition evolved from the ninth through several different kinds of changes. To maintain the currency of the material, some of the discussion of older programming languages has been removed. For example, the description of COBOL’s record operations was removed from Chapter 6 and that of Fortran’s Do statement was removed from Chapter 8. Likewise, the description of Ada’s generic subprograms was removed from Chapter 9 and the discussion of Ada’s asynchronous message passing was removed from Chapter 13. On the other hand, a section on closures, a section on calling subprograms indirectly, and a section on generic functions in...

...Bhavik Patel Individual: Programming Solution Problem It was my first time using the Visual Logic Program to create a program. Comparing to another program I have used before, Visual Logic was the easiest program to use. It was very easy to learn, and the tutorial on YouTube was very helpful. For this assignment, I had to create two programs that show any calculation or some math calculation. I’ve created a calculator in HTML and Java, and that was very difficult. I had to work hard to create the calculator but when I used Visual Logic to create a program calculation it was fairly easy. The two programs I create for this assignment are hours and rate and triangle calculation program. To create this program, it was fairly easy because by watching the YouTube videos I learned lot on how to use the program. On hours and rate calculation program it was fairly easy because the calculation was very simple. In order to create this program first, you need to have an input for hours. It’s crucial that you do all the steps in order because when you write a real program you will need to go in order. You can never skip any steps because when you skip steps the whole program will not work. After you create the input for hours, then you need to create an input for rates. Then you need to create an assignment with the formula that you are going to use to get a solution for hours * rate. For the assignment, you will type in Pay = Hours * Rate this is the formula to get a pay for a person...

...FUNDAMENTALS OF SURFACE MODES: ¥ COLLOIDS ¥ means ÒglueÓ in Greek ¥ was coined in 1861 by Thomas Graham. ¥ ¥ ¥ ¥ ¥ WHAT IS A COLLOID? usually consists of two phases; one continuous phase in which the other phase is dispersed. Size of particles: larger than the size of molecules and small enough for the dispersed phase to stay suspended for a longer period of time. ¥ No strict boundaries for the size limits. OFFICIAL DEFINITION ¥ In 1903 Wolfgang Ostwald formulated the official definition of a colloid: ¥ a system containing entities having at least one length scale in between 1nm and 1µm. ¥ For smaller particles there is no distinct boundaries between the phases and the system is considered a solution; ¥ for larger entities the particles will fall to the bottom due to the gravitational force, and the phases are separated. 1 2 3 MESOSCOPIC PHYSICS ¥ The particle size is in the so-called mesoscopic range in between the macroscopic and microscopic limits. LARGE INTERFACIAL AREA ¥ One very important quality of the colloids is the large interfacial area between the dispersed and the continuous phases. WHAT EFFECTS HAS THIS? ¥ This means that interface effects and hence the electromagnetic surface modes, are very important for the properties of the colloids. ¥ It costs energy to create this much surface and the particles would clump together if this isnÕt prevented. ¥ Usually the particles are charged and hence repel each other. 5 6 4 Four states...

... it increases the water movement out of the plant by a process called transpiration. When there is a shortage of water, the guard cells well get smaller and close the stomata, and the transpiration process will move slower. The osmolarity would be tested with solute concentrations ranging from 0.0 M to 0.6 M. The concentrations increased 0.1 M each time and the solute used was sucrose. The goal of this experiment was to determine which concentration had the least effect on the potato after being incubated. This information helped us estimate the osmolarity of the potato tuber tissue. Our group hypothesis is that the osmolarity of the potato will have the concentration with the 0.1 M solution. This hypothesis is based off the predicted outcome that smaller molarity concentrations will have the least effect on the potato. The more solute added to a solution decreases the concentration of water in most cases (Kosinski). The decrease in water concentration would then lead to a lower weight of the potato tuber once it has finished incubating. Methods & Materials: For experiment A you will need the following items: 1 large potato tuber Forceps petri dish razor blade DI water metric ruler 7 250 mL beakers/ or disposable cups balance that weighs to the nearest 0.01g sucrose...

... The purpose of the experiment was to see how abrasion works and how it affects rocks and minerals with the use of sugar cubes. I measured the mass of all 5 sugar cubes together then placed it in a jar with a lid on and shook it 20 times, as I was shaking the jar my lab partner recorded the mass that was taking with the number of times I shake the jar. After which we drew the shape of the sugar cubes when it was poured out on a paper, then we calculated the percent change. This procedure was repeated 5 times and with each trial the shaking time was increased by 20. After all the calculations was done, we graphed the data. After each trial the size and mass of the sugar cubes reduced, this was due to the pressure put on the jar as we were shaking it. Supposing little pressure was put on the jar, the outcome would have been different and would have shown little abrasion effects on minerals and rock so therefore this made me conclude that, for abrasion to have a greater impact on minerals and rocks the pressure of the water or wind must be strong to push the minerals against each other. Another factor that contributes to how abrasion works could be the amount of space the minerals and rocks have because during the experiment, the sugar cubes pumped into each other and the walls of the jar and since there wasn’t enough space for movement the sugar cubes weathered and reduce in size with the mass decreasing which I believe wouldn’t occur if there were to be enough space for the sugar...

...The data solute concentration of the egg was found by taking the average percent change in mass for each percent solute concentration used in the lab and putting the data into the graph(Mass vs. Solute Concentration Over 3 Days). According to the data from the class, the solute concentration inside an egg is 25.1%. The egg would be in an isotonic solution at 25.1% solute concentration. This is when the concentration outside the egg is equal with the concentration of water inside the egg. The point of equilibrium is the point at which the trendline crosses the x-axis. At this point, the egg would no longer gain or lose mass. If the concentrations are the same inside and outside the egg, diffusion will not be able to take place. All averages...

...Analysis of Carcinus maenas ingestion rates Materials and methods Part 1 - Control experiment Two mussels (mytilus edulis) were opened and the mussels inside cut into 4 pieces, producing 8 pieces of roughly equal size in total. A balance was then tared with a weighing boat placed on it. Each piece of mussel flesh was placed individually and in turn into the weighing boat to be weighed. The pieces were then placed into a plastic bucket half filled with filtered seawater. The weight, time of weighing and time of immersion into the bucket were all noted down for each piece of mussel. The position of each piece of flesh inside the bucket was also taken down so as not to mix them up. One of the eight pieces was left in the bucket for the duration of the experiment until being removed and weighed at the end and was written down as “the last”. Another piece was removed frequently throughout the experiment and was given the name “the one”. The last 6 pieces were each removed once and weighed at regular intervals to provide a range of submersion times. The experiment was run for roughly 20 minutes. The method for removing and weighing the pieces of mussel was kept consistent throughout the experiment. Each piece was removed, blotted clear of any excess water and weighed. If the piece of mussel was “the one”, it was returned to the bucket of seawater, if not, it was kept aside and moist for the crab feeding (Part 2). Once all of the pieces were removed and weighed (multiple times for “the...

...Salt of Sugar: Which One Dissolves Faster in Different Liquids Salt and sugar are used in many different ways. They are different in taste and purpose. Salt is use to make foods and vegetables saltier. Sugar is used to make food, candy, and fruits sweeter. Salt and sugar are also used in drinks (mostly sugar). So to find out which one dissolves faster, they will be in different liquids in different temperatures. Hypothesis: sugar will dissolve faster than salt. The liquids used are tea, water, and club soda. These liquids should have a different taste, color, odor, and purpose (O’Leary, Shelly, 91). Water molecules take up most of the room in the container (O’Leary, Shelly, 88). A solution is a mixture of a solute and solvent (O’Leary, Shelly, 88). During the experiment, keep a cup of plain liquid to compare (O’Leary, Shelly, 93). Nancy K O’Leary and Susan Shelly stated, “If you use mile or orange juice, for example, you won’t be able to watch salt and sugar dissolve,” (O’Leary, Shelly, 91). All liquids must be clear (O’Leary, Shelly, 92). Water is a solvent (O’Leary, Shelly, 90). BodnerResearchWeb.com stated, “Sugar dissolves in water because energy is given off when the slightly polar sucrose molecules form intermolecular dons with the polar water molecules.” (Bodner Research Web). The different temperatures are boiling (warm), cool, and room temperature. All of the liquids must be in the same temperature, or temperature will have to be used as...
