The Dependency of Bus Voltage and Frequency in Load Shedding
(Proceedings of Sustainable Research and Innovation Conference, 2014)—Load shedding schemes proposed in literature so far use voltage and frequency parameters separately. The individual consideration of these indices may not be reliable or effective, and may even lead to the over load ... -
The Dependency of Bus Voltage and Frequency in Load Shedding
(2014)Load shedding schemes proposed in literature so far use voltage and frequency parameters separately. The individual consideration of these indices may not be reliable or effective, and may even lead to the over load ... -
Design, Fabrication, and Testing of a Raspador for Simultaneous Extraction and Brushing of Sisal Fibers by Small-scale Sisal Farmers
(Taylor & Francis, 2021-07-10)Demand for natural fibers is on the rise as awareness of environmental protection keeps abreast. Sisal fibers, for instance, are largely utilized not only in the manufacture of mats, ropes, carpets, and sacks but also ... -
Determination of the maximum number of ASVT sub-stations that can be terminated on 132Kv line without voltage profile violation
(2016)In developing countries, there are many high voltage transmission lines which transverse villages not supplied with electricity to supply main towns and industrial areas. The conventional substations are too expensive and ... -
Developing a Campus Emergency Management Information System (CEMIS)
(Researchgate, 2015-10)Mobile phone technology is driving not only communication but also increasingly emergency and disaster management. Natural disasters and manmade threats such as terrorism constitute emergencies that are common today. ... -
Developing a Secure Messaging Platform in Mobile SMS Using Advanced Encryption Standard Concept
(2014-04)Billions of text messages are sent daily through GSM networks sent in plain text format which makes them susceptible to various attacks. With the increasing number of software crackers available for free in the internet, ... -
Development of a Web Based Electronic Procurement System
(2015-10)A well-functioning procurement system is an essential requirement for a developing country like Kenya. In order to promote development, proper management of scarce resources is vital. A system that ensures transparency, ... -
Distributed Slack Bus Model for a Wind-Based Distributed Generation using Combined Participation Factors
(International Journal of Emerging Technology and Advanced Engineering, 2012)With the increased penetration of distributed generation into the power distribution system, the traditional load flow analysis that assumes a single slack bus has become impractical. The existing literature focuses on ... -
Drying characteristics and some quality attributes of Rastrineobola argentea (Omena) and Stolephorus delicatulus (Kimarawali)
(AFRICAN SCHOLARLY SCIENCE COMMUNICATIONS TRUST, 2010)Rastrineobola argentea common name Omena and Stolephorus delicatulus common name Kimarawali are fishes that live in the freshwater and marine waters, respectively. Both are small in size, move in ... -
Dynamics of groundwater flow and upwelling pressure heads at a wetland zone in a headwater catchment
(Springer Nature, 2019)The rate and direction of groundwater flow are a function of the gradient of the hydraulic head, whose components are gravity head and pressure head. This paper presents results and analyses of field observations of pressure ... -
Effect of brining on the drying rate of tilapia (Oreochromis niloticus) in a solar tunnel dryer
(Acta Press, 2008)This study determined effect of on the drying rate of tilapia in a solar tunnel dryer. Tilapia fish was split into pieces of 4cm by 3cm by 9mm and soaked into four brine concentrations varying between 0-15%. Moisture content ... -
THE EFFECT OF FINE NON-METALLIC INCLUSIONS ON THE FATIGUE STRENGTH OF STRUCTURAL STEEL
(2015)The article discusses the results of a study investigating the effect of the number of fine non-metallic inclusions (up to2μm in size) on the fatigue strength of structural steel during rotary bending. The study was performed ... -
Effect of harvest age and thermal processing on poly-γ-glutamate folates and minerals in African cowpea leaves (Vigna unguiculata)
(Elsevier, 2012-03)Cowpea leaves (Vigna unguiculata) are highly consumed in Africa because the plant is easy to cultivate and highly disease/drought tolerant. The vegetables are harvested between 4 and 9 weeks of maturity. The objectives of ... -
Effect of Peripheral Velocity Difference Ratio on the Performance of Rubber Roll Huske
(The Japanese Society of Agricultural Machinery and Food Engineers, 2000)The difference in speed between the rubber rolls results in a shearing action on the rice grain as it passes between the rolls (Yamashita et al 1990, FA, 1995). The shearing force is thus dependent on the relative velocity ... -
Effects of Distributed Generation penetration on system power losses and voltage profiles
(International Journal of Scientific and Research Publication, 2013)In present times, the use of DG systems in large amounts in different power distribution systems has become very popular and is growing on with fast speed. Although it is considered that DG reduces losses and improves ... -
Effects of mildly heated, slightly acidic electrolyzed water on the disinfection and physicochemical properties of sliced carrot
(Elsevier, 2013)The efficacy of mildly heated, slightly acidic electrolyzed water (mildly heated SlAEW) at 45 °C for disinfection and maintenance of sliced carrot quality was studied. Mildly heated SlAEW (23 mg/L available chlorine, pH ... -
Effects of Polarization Mode Dispersion (PMD) on Raman Gain and PMD Measurement using an Optical Fibre Raman Amplifier
(IEEE, 2013-09-09)We experimentally investigate the effects of increase of the differential group delay (DGD) on Raman gain and gain value. It was found that the increase of DGD values lead to the formation and the increase in the number ... -
