Serious games have the potential to add value to the teaching and learning environment but are currently not used to its full potential in the Computer Science class. Many reasons why serious games are not used are debated in the literature and a particular problem identified from the literature is that educators find it difficult to select appropriate serious games for use in the classroom environment. The research philosophy adopted for this study included the Critical Social Theory paradigm and action research as the research method. The five phases of the action research process, namely diagnosing, action planning, action taking, evaluating and specifying learning were used to provide educators with a useful model to help with the selection of serious games for the Computer Science class. During the diagnosing phase, the problem for this study was identified and a questionnaire was used to determine educators‘ perceptions of serious games that confirmed the problem identified during the literature survey. During the action planning phase the evaluation of three serious game selection models, namely the four-dimensional framework, the RETAIN model and the Magic Bullet model were planned. Participants were provided with a checklist in the form of tables so that they could familiarise themselves with the models. During the action taking phase participants evaluated the four-dimensional framework, the RETAIN model and the Magic Bullet model using the checklists and examples provided to them. During the evaluation phase the three different models were evaluated by the participants and a questionnaire was used to gather data. The data were analysed and results were reported. A major problem was identified and it was decided to initiate a second cycle of the action research process. This time participants were provided with serious games and in a joint effort of the participants the problem was addressed. During the second cycle the problems identified in the first cycle was resolved. Finally this study is concluded with a reflection on all the research questions identified, a report on the findings, recommendations and a discussion of the limitations of the research project. / MSc (Computer Science)--North-West University, Vaal Triangle Campus, 2015

Competitive Shooting as a sport is becoming famous these days and analysis of shooting group or bullet group which is a process of analysis location of bullet holes in one shooting session and stands as a metric for Precision of the weapon, Shooter's Accuracy, his Consistency and helps in finding Accurate load for the Cartridge. Knowledge of these factors can help in improving one's shooting and fine-tuning skills as a Shooter. Bullet group is alsoinuenced by the Accuracy of Rie, Optimal hand load, free run distance, environmental conditions like humidity, temperature, ambient light, windspeed, Shooter's position. Analyzing the Bullet group can be done in various ways, one way of doing it is by taking a Digital Image and analyzing the Image and detecting positions of bullet holes and Calculating metrics from this Metrics like Geometry of bullet group, largest distance between two bullets, compactness of the bullet group on target. In this work, detection of bullet holes is done by using these techniques: Template matching, Histogram equalization, White Balancing, Median andGaussian altering and Peak detection algorithms. After obtaining positions of the bullet holes in the Image. Complete Automation can be done by using the training the Algorithm with a Machine learning framework with the help of Articial neural networks. The existing bullet group analysis software require the bullet group shot on a specifc target, which limits the shooters to shoot on a target of shooter's choice every time and, those targets are not universal and vary from place to place. This algorithm aims to work on various types of target, and taking a step towards making a more generalized and more versatile algorithm.

Development of modern software is a challenging task that requires software developers to leverageexisting functionality by means of reusable code structures, libraries, frameworks and middleware. This allows shortening development time and lowering costs, while keeping resulting software competitive, reliable and maintainable.However, developing software based on reuse of existing libraries and frameworks has its own challenges and requires programmers to be aware of the issuesthey might face.This paper discusses common difficultiesfaced by software developers while developing complex software systems based on reusable libraries and frameworks.The issuesare described along with possible solutions and exemplified by a custom UI framework named AxeZ. AxeZ is designed for customized UI development for Android phones and is built on top of OpenGL and Bullet Physics engine.As a result, AxeZ can be consideredan instanceof successfully designed framework, which implements solutions forthe challenges discussed in this paper. It provides an example of reusable framework targeted for wide area of application in UI programming

The current large concentration of wireless networks brings new horizons, but also new concerns. Failure to follow basic rules may produce far-reaching problems that could make more wrinkles to all affected managers and administrators. The aim of this thesis was to measure and compare the radio parameters of selected products and how they behave in neighboring interference and the speed they have while there are hidden nodes. The resulting values were measured in the laboratory network Wificolab and compared with the various support protocols. Possible effects on the specific situation are also analyzed in this thesis.

Firearms are present in two-thirds of United States households. As of 2003, roughly 500,000 projectile wounds occur annually in the United States. This costs an estimated 2.3 billion dollars of medical spending. The best treatment of gunshot wounds relies heavily on experience, but even with experience the unpredictable nature of ballistics can make treatment difficult. Wound ballistics studies the injury pattern of a particular bullet. Ballistic gelatin tests are used to analyze this pattern. A block of 10 or 20% ballistic gelatin is set and a bullet is fired through the block. Key characteristics of the wound profile seen in this test include: depth penetration, permanent cavity, and temporary cavity. Even with ballistic gelatin tests, there is still confusion and many unknowns throughout wound ballistic literature. Finite element analysis (FEA) can be used to reproduce the wound profile of a ballistic gelatin test. A .38 lead round nose was chosen to model. The bullet was assigned as an elastic plastic material and the ballistic gelatin block was assigned as an elastic plastic and viscoelastic material. SolidWorks®, TrueGrid®, and LS-DYNA® were used to create the models. Two elastic plastic and two viscoelastic simulations were developed from these models. Elastic Plastic 2 and Viscoelastic 1 were able to reproduce a depth penetration, temporary cavity, and permanent cavity. Elastic Plastic 1 and Viscoelastic 2 were unable to reproduce the temporary cavity. These simulations provided hopeful results, but further investigation is needed for contribution to the advancement of bullet wound treatment.

No / Biting the Bullet prepared a series of briefing papers on key issues for international agreement which fed into the July 2001 UN Conference on the Illicit Trade in Small Arms and Light Weapons in All its Aspects. At this conference, UN member states agreed a Programme of Action which is the primary global framework for tackling the proliferation of SALW. Biting the Bullet is currently engaged in two major areas of activity related to the implementation and further development of the Programme of Action. . Biting the Bullet, in partnership with the International Action Network on Small Arms (IANSA), produced a report monitoring states implementation of the programme of action for the 2003 Biennial Meeting of States (BMS) 'Implementing the Programme of Action 2003, followed by 2005 and 2006.
