Requirement engineering Exercise – the POS System solution Problem Description A POS (Point-Of-Sale) system is a computer system typically used to manage the sales in retail stores. It includes hardware components such as a computer‚ a bar code scanner‚ a printer and also software to manage the operation of the store. The most basic function of a POS system is to handle sales. When a customer arrives at a POS counter with goods to purchase‚ the cashier will start a new sale transaction. When the

Plants. The purpose of this project was to understand Mendel’s concept of a Dihybrid by performing similar crosses and calculated the phenotypes that are displayed. This project was conducted over many weeks by planting F1 seed and waiting for them to grow then cross-pollinating the F1 plants to produce the F2 seeds. Next students were to plant the F2 seeds and record the phenotypes. After all the data was collected we ran a statistical test called a Chi Squared to see if the hypothesis put foreword

Drosophila Melanogaster Introduction Drosophila mature through complete metamorphosis‚ as do all members of the order Diptera. [5] Diptera are commonly known as (true: having two wings) flies and include many familiar insects such as mosquitoes‚ black flies‚ midges‚ fruit flies‚ and house flies. [3] Drosophila melanogaster are most commonly known as fruit flies and are used in many genetic studies for a few simple reasons; they are small and easily handled‚ they have a short life cycle

weights c) Graph the original data and the two forecasts. Which of the two forecasting seem better? 4.18. Consider the following actual (A1) and forecast (F1) demand levels for a product: Time Period (t) Actual Demand (A1) Forecast Demand (F1) 1 50 50 2 42 50 3 56 48 4 46 50 5 49 The first forecast F1 was derived by observing A1 and setting F1 equal to A1. Subsequent forecasts were derived by exponential smoothing. Using the exponential smoothing method‚ find the forecast time for period 5. (Hint:

The Cognitive Interview and Eyewitness Credibility My Initial Hypothesis Hypothesis: The cognitive interview increases the credibility of eyewitness testimony by decreasing memory error and confabulations. Information is the lifeblood of a criminal investigation. The ability of investigators to obtain useful and accurate information from eyewitnesses of crimes is crucial to effective law enforcement‚ yet full and accurate recall is difficult to achieve (Stewart‚ 1985). Such elicitation
