Various authors have discovered formulae for numerical integration approximation. However these formulae always result to some amount of error which may differ in size depending on the formula. It's therefore important that a formula with highest precision has been discovered and should be implemented for use in numerical integration approximations...

We have designed a system which acts as power saver cum temperature display. It provides power to the fan and works only when somebody is in the room. In the absence of persons in the room, power is turned off and fan stops rotating. In addition, when somebody is in the room it will display the temperature and set the fan speed based on the tempera...

This paper provides an overview of two types of linear block codes: Hamming and cyclic codes. We have generated, encoded and decoded these codes as well as schemes and/or algorithms of error-detecting and error-correcting of these codes. We have managed to detect and correct errors in a communication channel using error detection and correction sch...

Abs t rac t In this paper we deal with the Euler equations for Isothermal gas. In analyzing the equations we obtain two real and distinct eigenvalues which enables us to determine the wave structure of the possible solutions to the Riemann problem set up. By considering the Rankine-Hugoniot condition we obtain the shock wave solution analytically....

Water is a very important natural resource that no creation can exist without it. Hence it has become a responsibility of every person to try and conserve this very precious resource. One of the ways of conservation is by building earth dams. However if they are not well managed these dams may end up drying up due to underground seepage leading to...

Stock exchange markets play a critical role in their economies. They facilitate the movement of capital, often aggregating resources of small individual savers into sufficiently large capital sums that can be successfully invested by commercial companies and at the same time provide opportunities for investors to generate returns. Fluctuation in th...

The role of Quality supplies in the performance of universities cannot be under estimated. Quality is the driving force in university performance. However its role is greatly affected by having quality systems in the universities. This research sought to assess the impact of quality of supplies on university performance using four indicators; cost...

The main objective of this study was to determine the key factors that determine the growth of the microfinance institutions. The target population was the people that participated in these MFI's which in many cases were found to be women groups, middle and low income earners in Voi, however concentration was mainly on the individuals / groups that...

There has been a large influx of refugees in Kenya from the neighboring countries due to their political instabilities. In this study, the number of refugees entering Kenya every year for a period 1993 to 2010 was analyzed using time series methods. Autocorrelation and partial autocorrelation function are calculated for the collected data. The appr...

Data protection is a vital tool to the development of any country. Certain challenges pose a threat to data protection in developing countries although the same challenges are evident in developed countries. For instance, technological advancement in information technology has challenged the existing mechanisms of data protection. Other threats to...

Sting Stigma Eradication Application forms the lifetime of fighting Stigma related to HIV/AIDS in Kenya and other developing countries in Africa. However, through this project there is remarkable improvement in approach of dealing with people affected or infected by HIV. It is therefore a turning point to a long journey of fighting the diseases in...

This study sought to investigate the extent to which strategic planning is practiced in secondary schools in Machakos district, Machakos County-Kenya. The research tried to answer the question " to what extent is strategic planning practiced in secondary school in Machakos district? " Data was collected from 63 secondary schools. The data collectio...

Regulation on access to Internet is a tool that is crucial to the growth of any nation. Some problems arise as attempts to implement regulation on access to Internet are concerned in both developing and developed countries. For example, privacy and lack of it on online information is a subject that has challenged the existing legal and regulatory i...

During fluid spill incidents involving damaged tanks, the amount of the product released may be uncertain. Many accidents occur under adverse conditions, so determining the volume lost by sounding the tanks may not be practical. In the first few hours, initial volume estimates often are based on visual observations of the resulting levels, a notori...

Certain integrals involving powers of the variable or powers of functions of the variable can be related to integrals of the same form but contai ning reduced powers and such relations are called REDUCTION FORMULAS. Successive use of such formulas will often allow a given integral to be expressed in terms of a much simpler one. In this paper we pre...

Kitung'u Mutua Nicholas Muthama (Corresponding Author) Taita Taveta University College Kenya Abstract The contribution of information technology (IT) cannot be underscored in the current century. Information technology is driving everything and has reduced the whole world into a global village. There is a low participation of females in information...

The protection of intellectual property rights is an important aspect in the development of any country. Despite measures undertaken both at international level and efforts by individual and law enforcement agencies, software piracy, and one form of violating intellectual property rights still persist. Certain challenges pose a threat to these effo...

Land surveying has been a challenge for many years both in developed and developing countries. For instance the triangular survey consumes a lot of time as several sides of the field need to be measured. Solutions to this have been reached by the discovery of M utua's formula of finding the area of a triangular shape. 1.0 Introduction In future the...

This paper investigates the relationship between university course and an individual " s career path. It seeks to find out job satisfaction as a result of these two variables. That is whether one is satisfied in their present area of employment, or simply the career path they are on and also if this particular area of employment is related to the u...

The purpose of this study is to present a case for the need for audit committee in Constituency Development Fund to promote corporate governance and accountability in constituency development fund management in Nairobi Province, Kenya. The study provides an analysis and critique of the extent of engagement research in the field of corporate governa...

This study investigates the environmental conservation costs of the local authorities in Kenya by analyzing the data collected from 90 of these local authorities. The population of the study is the 175 local authorities in Kenya. A sample of 90 local authorities has been used. Both statistical package for social sciences (SPSS) version 17 and Excel...

In this paper, a magnetohydrodynamic convection flow of an electrically conducting heat generating fluid past a semi-infinite vertical porous plate with variable suction is considered. The fluid flow is unsteady and a variable magnetic field is transversely applied to the plate. Evaluation of velocity gradients, temperature gradients and concentrat...

In this paper, Stokes problem of a free convective flow past a vertical infinite plate in a rotating system in presence of variable magnetic field is investigated. The fluid considered is electrically conducting. The equations governing the flow in this case are non-linear, thus they cannot be solved analytically. The finite difference method (FDM)...

Most institutions of higher learning such as universities and colleges world over provide for an electioneering process where students elect their union leaders in a democratic manner. This is of great importance as it inculcates the principle of democracy into the students who are at the peak of their learning stage and would need these skills for...

In this study, stokes problem of a convective flow past a vertical infinite plate in a rotating system in presence of variable magnetic field is considered. The fluid flow is unsteady and a variable magnetic field is transversely applied to the plate. Evaluation of velocity gradients and temperature gradients across the plate is done. Observations...
