USE-CASE DIAGRAM EXERCISE 1. Draw a use case diagram for an ATM machine with the following functionality. A customer’s interaction with the system involves logging in‚ making withdrawal requests‚ deposit requests‚ and balance inquiry requests. If the customer logs in‚ there is a possibility (although rare) that the system will confiscate the card (for example‚ if the login is incorrect or if the bank determines that the customer’s balance is significantly under zero). Card confiscation involves

to print a document or an organ. Is this a typing error or is it future brilliance?! “Fancy a new kidney? I’ll just print one off for you.” A brief glance at how future medicine for the next generation could be. With the invention of the ingenious Bio printer‚ this could be done! It is certainly creating a buzz in science and medical institutions globally. 3D printing is fast becoming a massive part of manufacturing and fabrication all over the world. Scientists and technological experts are able

Free-body diagrams are diagrams used to show the relative magnitude and direction of all forces acting upon an object in a given situation. A free-body diagram is a special example of the vector diagrams that were discussed in an earlier unit. These diagrams will be used throughout our study of physics. The size of the arrow in a free-body diagram reflects the magnitude of the force. The direction of the arrow shows the direction that the force is acting. Each force arrow in the diagram is labeled

Bio Cement The project aims at attaining high durability of concrete and gaining high strength of cement. We plan to make use of bacterial species which can hydrolyze the enzyme Urease efficiently to produce microbial concrete. Such bacterial are known to produce calcium which is useful in giving strength to cement. We are working in 2 stages. Stage 1: Here we check the effect of bacterial solution on cement mortar and along with that we check the effectiveness of the bacterial solution

Functional Decomposition Diagram An analyst first must understand an organization’s business functions before he or she can begin developing information systems. The functional decomposition diagram (FDD) is a business planning tool that depicts the hierarchy of business functions‚ processes‚ and subprocesses within an organization that are later described in detail using process models (chapter 6). The exercise of breaking down‚ or decomposing‚ the business functions into processes makes complex

The Iron-Carbon Diagram There are two iron-carbon equilibrium diagrams: - stable iron-graphite Fe-Gr - metastable iron-cementite Fe-Fe3C The stable condition usually takes a very long time to develop. The metastable diagram is of more interest. Fe3C iron carbide called cementite because it is hard. Following phases exist on Fe-Fe3C diagram: - liquid solution of iron and carbon (L) - ferrite ( ) – an interstitial solid solution of carbon in Fe (bcc). At room temperature ferrite is ductile but

Organism Physiology The course in which different kinds of living organisms are thought to have developed from earlier forms during the history of the earth is defined as Evolution. Many time organisms evolve due to environmental changes. To better understand evolution this paper will review a diagram of an organism and explain how the organism has evolved physiologically to become suited to fit its environment. Organism To understand the evolution of an organism it is important to understand

as Phase Diagrams By _________________ _________________ Material Science Lab #11 Report Introduction The purpose of this lab is to obtain the cooling curves for tin‚ lead and various alloys of these two metals. A phase diagram will be generated from these cooling curves. When a material is heated by adding energy at a constant rate‚ the temperature of the material will increase linearly with time‚ provided a phase transformation does not occur. As temperature of the sample becomes
