Abstract :

Meteotsunami are tsunami-like waves of meteorological origin than of seismic origin. This study is done as the first determination of Meteotsunami around the Sri Lankan coast. Sea level data were used from permanent tide gauge stations establish Colombo, Trincomalee, Kirinda interconnected to the global sea level monitoring network establish by the inter-governmental oceanographic   commission. Using high frequency readings, specific events were identified and further analyzed to remove tidal constituents and to obtain residual sea level variations. Residual sea level height was fast filtered and high frequency detected to identify Tsunami waves as same as seismic tsunami waves. The atmospheric pressure gradient was 1008-1011milibar hours while the wind speed increase from 14.21 to 31.90 mph in during same period. The amplitude   of isolated meteotsunami event was higher than four time of residual’s STD (σ). Meteotsunami event was identified during low tide with wave height > 0.3 m.

Abstract :

Operations Research (OR) is the application of scientific & mathematical techniques to study & analyse problems involving complex systems. It enables more effective decisions and more productive systems based on robust data, the fuller consideration of available options, and careful prognosis of outcomes and estimates of risk. It is considered a kit of scientific and programmable rules which provides the management a “quantitative basis” for decisions concerning the operation under its regulation.

An additional characteristic is that OR frequently attempts to find a best solution (referred to as an optimal solution) for the problem under consideration, rather than simply improving the status quo, the goal is to identify a best possible course of action.

Solid waste management is a convoluted task, absorbing a huge amount of resources and having a major environmental impact. It is one of the contemporary society’s most relevant issue. Computerized systems based on operations research techniques can aid decision makers to achieve remarkable cost savings as well as to improve waste reclamation. The objective of this paper is to present an updated survey of the most applicable operations research literature on solid waste management, mainly stressing on strategic and tactical issues. In addition develop and supply analytic support for optimal time, costing, pricing, or logistics networks for evaluation and/or implementation.

Abstract :

Tools with chromium nitride coating applied by triode pulverizing have been tested in routing and peeling of wood. The efficiency of coatings was proved in medium density fiberboard cutting, thus in heavy cutting conditions , as well as in routing of OSB (Oriented Strand Board) where a CrN coating of 1µm of thickness allowed to process up to 9 times longer than in case of non-dressed tool [1].

The purpose of this study was to examine the improvement of the tools wear in the peeling of MDF, achieved by special treatment of the tool. The modifications of the active surfaces of knives by applying hard coatings (CrAlN, CrSiN), have already given the promising results in the routing of the MDF [2]. The limiting factor of applying these coatings is their adhesion to the substrate –the cutting tool. For this reason the duplex treatments including nitriding and hard coating deposition were tested

Nitriding treatments have been performed inside a low vacuum furnace equipped with an impulsive current generator. The CrAlN coating was carried out by a dual magnetron sputtering system 8NORDIKO type 3500-1356 MHz.

The CrSiN films were deposited using DC/RF dual magnetron sputtering system (AC450). In order to study the Si content effect on the CrSiN properties, two targets (50.8 mm of diameter) of Cr (99.99%) and Si (99.99%) were used. ADC and RF (13.56 MHz) generator were used to polarize the Cr and Si targets, respectively. The Cr target/substrate distance was 80mm while the Si target/substrate distance was only 70mm.

The CrSiN coating have been prepared by institute FEMTO/ST of Besancon.

 The wood machining tests were performed using a laboratory microlathe which permits to make a simulation of the peeling process.

Abstract :

Education plays a critical role in promoting economic, social, cultural and political development of individuals, communities, nations and humanities. The Government of Kenya has consequently been allocating substantial resources to the education sector. In fact, the Government has been shouldering tuition fees in all public secondary schools since 2008. Despite these efforts by the Government, there are notable wastage in secondary school education sector. It has been noted that individuals, societies and humanity can realize returns to education if schools are operated efficiently. This study was designed to establish factors influencinginternal efficiency of public secondary schools in Bungoma County. Internal efficiency is the flow of students from the point of entry to the point of completion with minimum dropout and repetition. In this study, the indicators of internal efficiency are progression and completion rates. A descriptive survey design was used. The sampling units were public secondary schools in the County. By the time of study, there were 130 public secondary schools in the County.  Stratified random sampling was used to sample schools while purposive sampling was used to sample head teachers and class teachers in the sampled schools. Therefore the population was 130 head teachers and 520 teachers. A sample of 97 head teachers and 388 class teachers were drawn from a population. A questionnaire was used to gather data from head teachers and class teachers. Students’ record collection schedule was used to gather data to the study. The questionnaire and students’ record collection schedule were validated by constructing relevant items based on the objectives and reviewed by four lecturers in the Faculty of Education and Community Studies, Egerton University. The lecturers’ comments were incorporated in the final questionnaire and schedule to enhance validity. A reliability coefficient of the questionnaire was calculated and found to be 0.83 using Cronbach alpha. Descriptive statistics were used to analyze data. Descriptive statistics used were frequencies and percentages. The study established that public schools in Bungoma County were experiencing internal inefficiency. On average dropout rates were 24%. The findings imply that a substantive percentage of learners are not completing basic education. They drop out before acquiring necessary skills, knowledge and attitudes to actively participate in development process. The Ministry of education should enact appropriate strategies aimed at retaining learners in public secondary schools

Abstract :

In the present paper, the socioeconomic impact of weed control (manual and chemical + manual) of maize field technologies is assessed using indicators such as cropland, weed control, yield, total cost, gross margin (production value), net margin and net income. The article shows that in the Iffou region of Ivory Coast, where grass cover is a major problem, the use of herbicide reduces weed control time, contributes to solving the problem of scarcity and high cost of labor, and the positive effects on these indicators compared to manual weeding. However, the incidence of the use of herbicide remains low in relation to the number of farmers.

Education plays a critical role in promoting economic, social, cultural and political development of individuals, communities, nations and humanities. The Government of Kenya has consequently been allocating substantial resources to the education sector. In fact, the Government has been shouldering tuition fees in all public secondary schools since 2008. Despite these efforts by the Government, there are notable wastage in secondary school education sector. It has been noted that even when socio-economic status of parents is partially controlled for by subsidizing the cost of education, parental support and learner characteristics may impact on internal efficiency of schools. This study was therefore, designed to establish the teachers’ perceptions of the relationship between learner discipline and internal efficiency of public secondary schools in Bungoma County. The scope of   learne discipline was regular class attendance, sneaking from school, organizing strikes, using illegal drugs, engaging in sex and becoming pregnant. Internal efficiency is the flow of students from the point of entry to the point of completion with minimum dropout and repetition. In this study, the indicators of internal efficiency are progression and completion rates. A descriptive survey design was used. The sampling unitswere public secondary schools in the County. By the time of study, there were 130 public secondary schools in the County.  Stratified random sampling was used to sample schools while purposive sampling was used to sample head teachers and class teachers in the sampled schools.

The lecturers’ comments were incorporated in the final questionnaire and schedule to enhance validity. A reliability coefficient of the questionnaire was calculated and found to be 0.83 using Cronbach alpha. Both descriptive and inferential statistics were used to analyze data. Descriptive statistics used were frequencies and percentages. Inferential statistics used was Chi-square. The study established that public schools in Bungoma County were experiencing incidences of internal inefficiency. On average dropout rates were 24%. The study also established that parental role in guidance and counseling and counseling of learners,. The findings imply that a substantive percentage of learners are not completing basic education. They drop out before acquiring necessary skills, knowledge and attitudes to actively participate in development process. Guidance and counseling units with qualified staff should be established in every school to enhance learner discipline.

Abstract :

Despite the heavy investment in the ERP systems, it is not yet vivid how Kenyan Universities have involved users in the implementation of the enterprise resource planning system for the realization of their operations to obtain the benefits from the investment.  In close examination of previous studies on whether the ERP system implementation at the university was successful or a failure, most of the users responded that it was a success while a few indicated that the implementation was below average. This study sought to evaluate the challenges encountered in implementing the ERP systems in public universities in reference to user involvement. This research was guided by Information Systems Success Model and Diffusion of Innovation Theory. The researcher adopted a descriptive survey research design and the area of the study was at Kisii University. The target population comprised of 300 respondents. The researcher used questionnaires for data collection from the sample size of 65 respondents who were picked randomly. The collected data was analyzed by descriptive statistics methods of mean and standard deviation. Then the results were presented in form of tables. The overall results revealed that respondents agreed (M=2.31; SD=0.972) that there were challenges facing the implementation of the ERP systems in public universities in Kenya. The study concluded that the ERP system implementations are faced by varied impediments which should be overcome to ensure smooth information systems implementation. Further the study recommended that in as much as the university rolled out the implementation of the ERP system which is ongoing, it has not fully done so to realize its full value of the system and as such the university should consider the ERP system implementation challenges for they are fundamental for the success of the ERP system implementation in public universities.
