This seminar reviews features selection method of medical image processing. How image is selected by using different types of method like: screening, scanning and selecting. We discussed on feature selection technique which is widely used for data mining and knowledge discovery and it allows elimination of (irrelevant/redundant) features, whilst retaining the underlying discriminatory information, feature selection implies less data transmission and efficient data mining. It emphasized the need for further research in the field of pattern recognition that can effectively determine the situation with captured portion of human body.

Time synchronization is an important aspect in Wireless Sensor Networks (WSN). They make wide use of synchronized time in many contexts like data fusion etc. Without synchronizing, the sensed data will lose valuable context. Existing time synchronization methods cannot be used with such wireless networks as at the time of their designing such networks were not foreseen. So either present synchronization techniques need to be extended to WSN or are to be approached in different way. While designing synchronizing algorithm, requirements of energy, cost, scope, scalability, lifetime of WSN should be kept in mind. In this paper different approach for time synchronization in sensor networks is presented. This paper proposes an improved algorithm used for WSN in fixed deployment scenario of nodes. The Proposed algorithm is compared with Reference-Broadcast Synchronization (RBS) synchronization technique. Simulation results and Performance analysis shows that compared with RBS synchronization algorithms, the proposed time synchronization algorithm takes shorter time for synchronizing whole network and is more energy efficient.

This study sought to establish the availability and relevancy of transitional programmes for adolescents with hearing impairment in schools in Bulawayo. According to Lehmann, Ravies and Lourin (2003), there is no amount of modern special educational programming that would be complete without making reference to transition from school to community life. A descriptive survey design was employed in conducting the study while a questionnaire and face to face interviews were used in triangulation to elicit data. Data were presented in tables, and bar-charts and analysed using frequency counts, percentages, Likert Scale and descriptive summaries. The major findings of the study were that, while some vocational subjects were available and appeared relevant to the future needs of the adolescents with hearing impairment in schools in Bulawayo, the subjects were largely offered at theoretical level. There were no work experience and attachment arrangements save for one school which however relied on one local factory which was facing collapse at the time of the study. This made the transition programmes generally irrelevant to the real future lives of the adolescents. The study also found out that, the schools did not deliberately teach social skills to adolescent with hearing impairment often due to communication barriers. From the findings, the study concluded that what schools in Bulawayo regarded to be transition programmes were in effect isolated transition activities that hardly constituted a programme. In any case, these activities did not adequately prepare the adolescents with hearing impairment in schools in Bulawayo for adult life. The study went on to recommended staff development of school administrators and teachers in transition programming. The study also recommend work experience and attachment arrangements, multi-stakeholder participation, formulation of specific policies and improvement of resourcing of transition programmes for adolescents with hearing impairment in Bulawayo.

'Hunhu/Ubuntu‟ forms the foundation of the African conception of humanism. This paper conceptualizes "hunhu/ubuntu‟ as a traditional African philosophy which thrives on the vision of a perfect and virtuous individual. It traces the emergence of "hunhu/ubuntu‟ as a common ground of consciousness that all Africans or Bantu tribes in Zimbabwe share (Kamalu,1990). Hunhu/Ubuntu is conceptualized as a symbol of African identity. A brief critique of "hunhu/ubuntu‟ as a communal and not an autonomous world view of humanness is provided. The paper also argues a case to show that lack of standardization of the dictates and the formalization of enculturation processes of "hunhu/ubuntu‟ are the core causes of the perceived lack of "hunhu/ubuntu‟ among the youths in Zimbabwe today. The generational gap and limited formal engagements on the dictates of hunhu/ubuntu between the adults and the youths of today could be the other causes. On these bases, the paper recommends the development of a flexible vision of "hunhu/ubuntu‟ as a function of nationhood, globalization and changing times through formal systems such as deliberate citizenship education.

The problem of natural convection heat transfer from a vertical fin array is theoretically formulated by treating the adjacent internal fins as two fin enclosures. Three dimensional governing equations of mass, momentum and energy for the fluid in the two-fin enclosure together with the neat conduction equations in the fins are numerically solved using ADI method. The heat lost to the ambient fluid from the two end fins of the fin array is also computed separately. Heat transfer by radiation is also considered in the analysis. The numerical results are compared with the experimental data available in literature showing good agreement. The effects of system parameters such as the base temperature, fin height, fin spacing are studied on heat transfer rate and effectiveness of the vertical fin array. Results show that fin spacing is most significant parameter and there exists an optimum value for the fin spacing for which the heat transfer rate from the fin array is maximized. Results also show that higher heat transfer rates are obtained with vertical fin array of the same geometry. Study is limited to laminar convection only.

In this paper we study the travelling wave solutions of a reaction-diffusion system with a slow reaction and a slow diffusion for one component. We use a semi-implicit method and finite element method (COMSOL software) for solving this system. We compare both methods and we found an excellent agreement between the solutions.

The main objective of this research study was to develop a palatable ready to drink fruit beverage which will be acceptable to consumers using lemon and lime concentrates. The aim of this research project is to help reduce the large stores of lemon concentrate in stock at Mazoe Citrus Estate since this company had been facing challenges of fermentation and gelation of the lemon concentrate due to long term storage. Three lemon and lime nectar samples (sample A, B, C) containing different juice percentages were developed using both qualitative and quantitative research designs. Through sensory evaluation by a panel of 20 respondents from Mazoe Citrus, Midlands State University Food Science department and residents of Senga, the most preferred nectar sample was identified. Sample C, which was the most preferred nectar sample was then tested for brix, pH, titratable acidity, pulp content, number of specks and microbes. The laboratory assessment results showed that the lemon and lime nectar conformed to the stipulated specifications of nectars and the lemon and lime nectar produced scored a shelf life of one month.
