A sub-phase of the requirements specifications which deems high importance is Software Requirements Specification (SRS). SRS is a description of a behavioral aspects of the system which includes all the interactions that the users will have with the product (Stellman & Greene, 2005).
Modeling is a central part of all activities that lead up to the deployment of a good software (Booch et al, 2005). Modeling is exactly the role that Unified Modeling Language plays in requirements specifications. The role of Unified Modeling Language is to model interactive systems, whose behaviors emerge from the interaction of their components with each other and with the environment (Goldin et al., 2001). In traditional computation, algorithmic models were sufficient for description of requirements. However, todays interactive systems which are capable of self reconfiguring and adapting to their environment, algorithm tools do not suffice. Unlike traditional procedural languages, UML provides support for the inherently open-ended preliminary steps of systems analysis and specification, which are becoming increasingly complex (Wegner, 1997). UML is used to visualize, specify, construct and document the artifacts of the software-intensive system. A software of any nature or proportion will have multiple methods, functions, interface and external and internal accesses. To support such a broad mix of entities, UML provides different views to analyze this software. Analysis of each of this views gives the software designer a set of requirements which can be consequently forward engineered. The prominent views provided by UML are Use Case View, Component View, Deployment View, Concurrency View and Logical View (Eriksson & Penker, 1998).

Use Case View: Requirements capture has two objectives: to find the true requirements and to represent them n a suitable way for the users, customers and developers (Jacobson et al., 1999). True requirements are the end user functionalities desired by the user of the system. These functionalities must be presented in a way such that users spend minimum amount of time understanding it. Use Cases can be applied to capture the intended behavior of the system being developed, without having to specify how that behavior is implemented (Booch et al., 2005). UML provides Use Case diagrams to model the Use Case View.

Logical View: The purpose of logical view is to specify the functional requirements of the system. This means that the logical view shows both the static and dynamic views of the system. The logical view concentrates on getting the best logical grouping of functionality into objects (fincher, 2007). The main artifact of logical view is the design model which gives a concrete description of the functional behavior of the system. UML provides Class diagrams and Object diagrams to model ...Download file to see next pagesRead More

Materials in Engineering Systems - Uranium

...?School of Engineering & Applied Science Materials in Engineering Systems EAS 213 Dr. Inserts Research Paper onMaterials Date: December 14, 2011 Uranium is an important resource because of its application as a fuel for nuclear reactors. However, its production, use, and disposal remain very controversial because of its radioactive nature. It carries with it the risk of radiation poisoning which has short term and long-term effects. Politically, it is a divisive issue because of the varying interests, which range from risk of nuclear proliferation, military might, sovereignty, to environmental concern. Many regulatory agencies and activist groups work towards certain ends in the debate....

Engineering accomplishment-Air traffic control systems

...? Engineering Accomplishment: Air traffic Control Systems Engineering Accomplishment: Air traffic Control Systems Introduction The invention of the air traffic control system is arguably one of the greatest engineering achievements in the aviation industry. It is reported that prior to 1930 before its invention, there were no much need of an organized air traffic control system in the US (Federal Aviation Administration, 2008). The reason being that airplanes were still not so many and almost all aerial traffic in the U.S. moved during the day with sufficient lighting and a clear sky. This meant that a pilot could easily see other aircrafts when taking off, landing or when on flight on the sky. Traffic avoidance was based on ‘see... ...

...SYSTEMS ENGINEERING FOR MANAGERS 420555 Systems Engineering For Managers The Weakening US Economy Inflation has been the major cause of the weakening economy and the US dollar. It happens from the excess money which is being made and released by the government and spent by the citizens as well as investors with no equal amount of trade and products being made. This has taken place as interest rates go low and people tend to buy more of these products and other services. This shot up the country's spending that created a need for more money. Trade deficit in other countries such as China lower rates of interest creates inflation. The dollars thus flowed to such countries...

...the second regulates the reaction on the sum of recent errors and the third determines the reaction to the rate of error change. The sum of these three is taken as output to a control element. By adjusting the proportional, the integral and the derivative values, the PID can give control action for specific requirements. The effectiveness of the controller is ascertained as the viability to respond to an error and stage to which the controller overshoots the set-point and the degree of system oscillation. An improved PID tuning method can be used for marine diesel engine governors that face problems under extreme propeller load fluctuation because of changes in weather or sea...
