SQUARE WAVE TO SINOUNSIDAL WAVE FORM

The availability and stability of electrical energy is necessary for domestic and industrial use. But unfortunately the monopoly which the Power holding company of Nigeria (PHCN) enjoys in this country is not in favor of the electricity users, because the supply is never constant and damages occur due to inconsistency of this supply is very enormous. However, millions of naira’s are lost every day in the commercial and industrial sectors, and even at the same time a lot of Lives are wasted ...

Defluoridation of Water using Moringa Oleifera.

ABSTRACTThe primary objective of this study is to identify the most appropriate herbal plants for the removal of contaminants from water and also to develop a water treatment kit at an affordable cost for the society.  Moringa Oleifera was chosen for this study, the effectiveness of these herbs in the removal of fluoride from water shows that Moringa Oleifera is economically viable, physically feasible and socially acceptable. Moringa Oleifera seed is an organic material that has proven effe...

Design and Construction of an Integrated Mechanized Cassava Mash and Garri Sifter (Sieve)

Cassava is produced in a large quantity in Nigeria. One of the products emerging from its processing has turned out to be a major staple food in the nation, which is ‘garri’. Due to insufficient and inadequate processing equipment; cassava has been susceptible to wastage and ‘garri’ production has been reduced in scale, thereby resulting in insufficiency and high cost of ’garri’ in the market. In order to ease the production process, a compact mechanized cassava mash/‘garri...

The Effect Of Total Dissolved Solids, Salinity And Electrical Conductivity Parameters Of Water On Abundance Of Anopheles Mosquito Larvae In Different Breeding Sites Of Kapiri Mposhi

Malaria is a global public health problem, caused by malaria parasites transmitted by the vector adult female Anopheles mosquitoes. The life cycle of Anopheles mosquito (Order: Diptera) has six stages egg, four larvae instars and pupa. The immature stages are aquatic and determine the abundance, distribution and fitness of the adult Anopheles mosquito. The physicochemical parameters (Conductivity, Salinity and Total Dissolved solids) of water affects survival and development of the larvae. Th...

Wind Power and Solar PV renewable energy generation on an Island of Great Cumbrae

The aim of the project is to design a renewable energy system that can meet the current and projected electricity demands for the island of Great Cumbrae. This should be achieved by providing a stable electricity output and the meet the calculated total annual base load supply of 11.29 GWh. In addition to providing a stable supply of electricity, the environment and social impacts that arise from the project relating to Great Cumbrae should be minimised as well as coi...

ONE ON ONE TECHNOLOGY AND ITS EFFECT ON STUDENT ACADEMICS AND MOTIVATION

This research is a quantitative study using 4th grade reassessment on one on one technology and its effect on student achievement and motivation. 

RADIOISOTOPE THERMOELECTRIC POWER GENERATION

Sustainable energy sources have been a topic of interest over a period of time for many researchers. Nuclear energy is one of the sources that have long been exploited for generating heat and electricity both in large scale and small scale. One of the methods for converting this heat into electrical power is using thermoelectric generators. Radioisotope thermoelectric generators are currently the longest-lived sources of energy; it does not require any human maintenance or refuelling. This pa...

Construction of a Battery Cage with Manually Operated Waste Conveyor

This is a research work carried out on battery cage system of poultry management. It's all about how to minimize waste from poultry birds and also how to convey waste by employing the help of a belt conveyor 

Empirical Validation of Photo-voltaic Power Output Forecasting Methods

The electricity produced by renewable energy sources (RES) is constantly increasing world￾wide thanks to government policies and technological advancements. Photo voltaic cells are actually a fast rising technology as the source of its power is a commodity that is abundant in this part of the hemisphere. Uncertainty also dominates in the area of the conditions at which the photovoltaic cells are operating, their optimal weather conditions and the effect of the conditions on their output...

DESIGN AND IMPLEMENTATION OF AN INTERNET OF THINGS (IoT) BASED SMART WASTE BIN FOR FILL LEVEL MONITORING AND BIODEGRADABILITY DETECTION

                                                              ABSTRACT ABSTRACT  It is not doubtful that effective and efficient waste management is essential for the development of a smart city. In developing and most developed countries of the world, overflowing waste from waste bins located at strategic positions in streets or close to residential areas both destroys the aesthetics of the environment and constitutes air pollution to the environs ...

Biochemical and biometrics characterization of five varieties of Pistacia vera L. grown in Maoussa experimental station (northwest of Algeria)

Both biometric behavior study and fruit biochemical analysis of five varieties of Syrian Pistacia vera introduced in Algeria in 1998 and raised in semi-arid bioclimatic stage (common Maoussa, Mascara, Algeria) led to a qualitative comparison. Based on the pistachio descriptor criteria established by the International Plant Genetic Resources Institute in 1997, characterization and descriptor of female varieties of pistachio were performed. The obtained results allow the bet...

Comparative Study of The Emergence and Growth of Young Seedlings of Five Varieties of Pistachio (Pistacia vera L.) of Syrian Origin

The present work is to study the emergence and growth of seedlings of five pistachio varieties that are: Batouri, Achouri, Neb-Djemel, Adjmi and Bayadhi. The study was conducted in a greenhouse temperature and photoperiod were controlled. The seeds are germinated in pots filled with peat without going through the damp cold stratification at a temperature of 4ºC. The results obtained showed that growth parameters (length and diameter of the plants) revealed significant tes...

EFFECT OF SALINITY ON THE PHYSIOLOGICAL BEHAVIOR OF THE OLIVE TREE (VARIETY SIGOISE)

Salinity is a major problem directly affecting the ecological balance and the development of agriculture in the Mediterranean basin, particularly North Africa. This phenomenon is considered as the most important abiotic factor limiting crops growth and productivity, degrading and polluting soils in arid and semi-arid. In order to study the influence of salinity, on the physiological parameters and to assess the potential of adaptation of the olive tree in a saline environment, three parcels c...

Application of fuzzy clustering data mining approach to garment sizing problem

ABSTRACTCurrently owing to the annual increase of data, there is urgent need for anthropometric database and useful approaches, in designing machine, equipment, facilities, workspace and other products. Fuzzy clustering which is an important way of clustering is an approach where an object is grouped into more than one partitions. The approach is used to bridge the gap between the anthropometry dimension of an individual and garment size which is a problem attributed to the size of the ...

Analytical Modeling and Optimization of a Solar Chimney Power Plant

Wind and solar resources are diluted and intermittent on the earth; their combination allowed increasing their availability and stability. At great scale, the use of Solar Chimney Power Plant (SCPP) technique constitutes a promising alternative to fossil fuel for generating electrical power particularly in rich regions of natural resources such as solar, wind, terrain, built material,water…etc.). Recently, various research works investigate the design and optimization of thesesystems u...
