Teaching assistant assignment planner

Doing TA assignment manually is a tedious and error-prone process, which means it is not only time-consuming but also susceptible to human errors such as schedule conflicts, multiple assignments and overload assignments. Teaching Assistant Assignment Planner (TAAP)--a software tool implemented using Java in Windows environment--facilitates the process of doing TA assignment. It is a semi-automatic software system, which helps to promote staff productivity, eliminate human errors and generate status reports. Both the TAAP design and implementation are presented in this major report. The issues to be addressed are environment setup, requirement analysis, detailed design, final implementation and improvement suggestion. Environment setup identifies the hardware and software requirements along with some useful background information. Requirement analysis defines the database scheme to be used, explores the system functionality and performs the task analysis. Detailed design presents the MVC design pattern, explains how MVC is being applied, and elaborates the design detail in the UML notations. Final implementation only covers critical coding issues such as database access from Java, data representation in GUI and database manipulation. The improvement suggestion sheds the light for the future improvement of TAAP, e.g. the migration to a web-based application

VCU Media Lab

We propose the establishment of a VCU Media Lab – a professional creative media technology unit whose mission is to support the development, design, production and delivery of innovative media, multimedia, computer-based instruction, publications and tools in support of VCU education, research and marketing initiatives. This centrally administered, budgeted and resourced facility will acknowledge, refine, focus and expand media services that are currently being provided at VCU in a decentralized manner

Forty hours of declarative programming: Teaching Prolog at the Junior College Utrecht

This paper documents our experience using declarative languages to give secondary school students a first taste of Computer Science. The course aims to teach students a bit about programming in Prolog, but also exposes them to important Computer Science concepts, such as unification or searching strategies. Using Haskell's Snap Framework in combination with our own NanoProlog library, we have developed a web application to teach this course.Comment: In Proceedings TFPIE 2012, arXiv:1301.465

Experimental and simulation analysis for performance enhancement of elliptical savonius wind turbine by modifying blade shapes

Savonius turbines are drag-based rotors which operate due to a pressure difference between the advancing and retreating blades. After going through an exhaustive literature review, it was realized that the Savonius wind turbines are an applicable option at low wind speed areas, where the counterpart of these turbines cannot work efficiently. Nevertheless, the existing design is still under research to make it more applicable in urban areas. Therefore, the research objective was to develop and test an elliptical Savonius wind turbine to improving its performance in terms of power and torque coefficients by modifying blade shapes and overlap ratio. In the beginning, a series of 2D unsteady simulations (CFD-Fluent version 19.1) of the Savonius elliptical turbine has been performed to study the overlap ratio of blades and the effect of the turbulence models. Conventional elliptical Savonius turbine was modified by changing the overlap ratio from the value (OR=0.15) to (OR=0.2) and called as the Model-A. Then, the concave surface of the blade Model-A was modified (as zigzag shape) and called as Model-B. The blade shape of the Model-B was modified by adding bypass channels for each blade to creating new configuration was called the Model-C. The experimental work begins with the manufacturing of the models (A, B and C) of the blade using 3D printing technology. Models were tested by the wind tunnel in Aerodynamic laboratory (UTHM) with four cases of wind velocity. 2D simulation result for Model-A at OR= 0.2, where the increase in maximum power coefficient value obtained was 3.85% and 7.69% compared to overlap ratio (0.15 and 0.1), respectively. The result of the experimental test was obtained the maximum power coefficient (0.296, 0.292, 0.291, and 0.295) at wind velocity (6 m/s, 8 m/s, 9 m/s, and 10 m/s), respectively for Model-B. The Model-C result in the maximum power coefficient (0.28) compared with Model-A (0.26). The 3D unsteady simulation also has been done to visualisation the behaviour of flow around Model-B and it show a good agreement with experimental test results
