Unified Modelling Language - Campus Housing Service
E- Usability of different diagrams in the systems analysis and design phase17A- Use Case Diagram A use case diagram demonstrates the overall behavior or working of a system against any external response/input. Additionally, it encompasses the details regarding overall system working and operations. It helps system programmers to better understand the major aspects of a system (Dennis et al., 2008; Pressman, 2001; Sommerville, 2004). In this scenario, the use case for Campus Housing Service system ...
Unified Modeling Language Analysis
The paper "Unified Modeling Language Analysis" is a wonderful example of a report on logic and programming. Unified Modeling Language is a visual or graphical modeling language. Unified Modeling Language Analysis is a standardized way of representing business objects or processes in visual and graphical models. It normally uses a diagram as its form of notation to represent different business entities. This form of language is also used mostly by business analysts to develop software systems for ...
Designing and Simulating a Control System
The paper "Designing and Simulating a Control System" is a wonderful example of a report on design. The design and simulation of a vapor compression refrigeration control system will be discussed in the paper. The control system under consideration is based on industrial, large-scale use and is specialized in the cooling of electronic equipment. The approach used in the design and simulation of the refrigeration control system is based on the energy conservation concept. The primary objective here ...

The Concept of Social Imagination
The paper "The Concept of Social Imagination" is a wonderful example of an assignment on category. The concept of social imagination refers to the process of examining an individual’s attitudes and behaviours within the context of social forces that mould them. It is based on the assumption that changes in a society deeply influence human lives (Brewer 2004). This essay explores how social imagination help understand the relationships between personal histories and broader social trends. This ...
Analysis Of Real-time System
A real time system is defined as that whose response is dependent upon a fixed frame of time. The input to the system affects the output within a defined range of time outside of which it becomes obsolete. On the converse, a normal system, which is non real time is that whose response is not depended upon a fixed range of time and hence the output is a function of both the current input and any previous inputs. For the Muddy springs bottled water company, the proposed system would incorporate operator’s ...
Strain Gauge: Measurement and Instrumentation
The paper "Strain Gauge: Measurement and Instrumentation" is a great example of a lab report on engineering and construction. To there is a dire need for the designs to be stronger and lighter and tested in a thorough manner. This need leads to the emphasis on analyzing the subject of experimental stress and the methods that are used to measure strain. In this study, a strain gauge was attached to the bending beam. The objective of the experiment involves using the bending beam and the circuit bridge ...
