...maintainability, reusability, and safety. These two functions work intangible with common attributes and similar qualities that behavioral requirements deal with output values and deadlines, and developing quality attributes deals with deadlines and maintaining the goals achieved. One major issue inherent with requirements is discovering significant errors later during maintenance can be very costly. It is recommended to detect errors during the design and development so as is less expensive. The goal of requirements phase is to establish and specify precisely what the software must do without describing how to do it (Thayer and Dorfman, 2013). The ultimate outcome is to specify the problem to be solved and not its solutions. The average person doesn’t understand very technical solutions unless they studied it for a profession, but how to solve the problem. Some of the difficulties that compound the problem are that customer/clients most often do not know what they want or how to describe what the software should do or functions it’s to perform. As well, customer/clients cannot articulate for practical reasons the vision of the software. Also many cannot control the...

...body is a solid body that can be parts of a structure or machine that are perfectly rigid and do not deform, even under large forces. This is important because Statics deal primarily with the calculation of external forces which act on rigid bodies in equilibrium. 3. Describe 3 real world examples of statics that might require engineering analysis. At least one example should be an object moving under constant velocity. Include an explanation of why the analysis is needed. Try to think beyond examples in the book. Skyscrapers will requires engineering analysis on steel beam loads, rivets, and truss and floor systems. There is allot of forces acting on rigid bodies in relationship to height. Analyzing this can help engineers design foundations to support ever record breaking heights. Wind acts as force. Engineers need to understand how rigid components are affected by wind at various speeds. A hoist requires engineering analysis to determine the maximum load it can lift. To heavy and the hoist can break. Rigid components in a spacecraft are subjected to thrust forces at launch. Allot of engineering analysis is required so a spacecraft do not break apart during launch. Also forces applied to a spacecraft on return flights entering our earth atmosphere and how those forces act on it. 4.

...TITRIMETRIC ANALYSIS 3.7.1. BASIC PRINCIPLES In titrimetric analysis we volumetrically measure the amount of reagent, often called a titrant, required to complete a chemical reaction with the analyte. A generic chemical reaction for titrimetric analysis is ����+����→���������������� Where: a moles of analyte A contained in the sample reacts with t moles of the titrant T in the titrant solution. The reaction is generally carried out in a flask containing the liquid or dissolved sample. Titrant solution is volumetrically delivered to the reaction flask using a burette. Delivery of the titrant is called a titration. The titration is complete when sufficient titrant has been added to react with all the analyte. This is called the equivalence point. An indicator is often added to the reaction flask to signal when all of the analyte has reacted. The titrant volume where the signal is generated is called the end point. The equivalence and end points are rarely the same. SUCCESSFUL TITRATIONS A few rules of thumb for designing a successful titration are: 1. The titrant should either be a standard or should be standardized. 2. The reaction should proceed to a stable and well defined equivalence point. 3. The equivalence point must be able to be detected. 4. The titrant’s and sample’s volume or mass must be accurately known. 5. The reaction must proceed by a definite chemistry. There should be complicating side reactions. 6...

...Analysis of Iron Supplement by Redox Titration Purpose: to calculate the percentage of iron in a vitamin supplement by titrating using a KMnO4 solution. Materials: .01 M Potassium Permanganate (KMnO4) Iron Supplement Tablets Distilled water 6 M Sulfuric Acid (H2SO4) 50 mL buret 3 Erlenmeyer Flasks Heat Plate Procedure: First, mass the iron supplement and crush up using a mortar and pestle before adding to 25 mL of distilled water. Next, heat and stir the crushed tablet solution to dissolve it in the water and add 1 mL of 6 M sulfuric acid. Finally, titrate with the 50 mL buret using the potassium permanganate solution and record the volume taken from the buret once neutralized. Conclusion: Titration is the volumetric measurement of a solution of known concentration when it reacts completely with a measured volume or mass of another substance. (Source: dunfried.wikispaces.com). In this experiment, the titrant, the substance doing the titration, is the standardized potassium permanganate solution. This solution will determine the amount of analyte (a chemical substance that is the subject of chemical analysis (source: Merriam-webster.com)) or iron (II) in the supplement pills. Using a balanced redox reaction (one with both an oxidation and reduction of electrons) for this experiment, the percent of iron in the sample can be calculated through basic stoichiometry. This percentage can be compared to the percentage labeled on the bottle of pills to determine...

Under this program, customer shopping trends are identified and rewarded. This in turn can support the objectives providing an inventory selection of specialty foods that their customers’ desire increasing the favorable of repeat shoppers to the Kudler name. In order for the program to be effective, customers are given a swipe card that contains their information in a bar-code format. The swipe card enables Kudler stores to electronically record the frequency of purchases made by the consumer refiguring the points accumulated during time of checkout. The point system can be explained as so for every one dollar spent with the store one point is accumulated for that transaction. The existing information technology (IT) database the company utilizes is identified as a “customer table” that has each customer’s mailing information regarding the demographics for birthdays and anniversaries. This will need to be revamped to include the points accrued per capita for Frequent Shopper’s cumulative transactions. When the frequent shopper has accumulated the specified range of points determined by Kudler, the reward(s) of their choosing can be redeemed at the nearest store location.
