“Factors Affecting Safety Performance On Construction Sites In Sudan”

ABSTRACT The construction industry is considered one of the most hazardous industries, not only in developing countries but also throughout the world due to its unique nature. This makes more attention to construction safety to improve the safety performance of construction companies. This research aims to identify the factors affecting the construction safety and to establish rules to assess and improve the construction safety of construction companies. The questionnaire design is composed ...

Microstructure And Durability Performance Of Concrete Containing Empty Palm Oil Fruit Bunch Ash As Partial Replacement Of Ordinary Portland Cement

ABSTRACT The production of concrete as a civil engineering material is highly dependent on the availability of its constituent materials. However, most of these materials are no more readily available. In order to solve this problem, many researches has been carried out on the use of agricultural waste as construction material, one of this material is Empty Palm Oil Fruit Bunch Ash (EPO - FBA). (EPO - FBA) is an agricultural waste material which is gotten after burning empty palm oil fru...

Classification And Strength Characteristics Of Soils Along Faculty Of Engineering Road Federal University Oye Ekiti, Ikole Campus

ABSTRACT This research project aims at classifying and determining the strength characteristics of soils along Faculty of Engineering road, Federal University Oye Ekiti, lkole campus. The road spans about 338m. The relevant soil tests include; particle size analysis, consistency limits (liquid, plastic, and shrinkage limits), natural moisture contents, specific gravity, compaction test, consolidation and shear strength tests. Liquid limit (LL) is defined as the moisture content, in perc...

Modeling And Simulation For Kaplan Turbine In Roseires Power Plant

ABSTRACT The aim of this thesis is to develop a model to study the performance of Kaplan turbine of unit number four in rosiers hydro power station .To achieve this aim , a model was develop using simulation soft ware matlab/simulink based on the dynamic equations of Kaplan turbine , then the simulation results were compared with the results of the real system in case of loading and idling mode .The simulation results showed very good agreement with the results of the real system , with smal...

Domestic Water Treatment In Ikole Ekiti Using Moringa Oleifera Seed Powder

ABSTRACT Most people living in rural communities, have no access to good domestic water for consumption. The inhabitants depends on rain water, well water and sometimes surface water for consumption. Improper treatment of water gotten from these sources, can lead to the spread of water borne diseases, because, sometimes the water gotten from these sources are turbid. Although, some inhabitants use alum to treat the water so as to make the water clear. But excessive usage of alum to trea...

Assessment Of Geotechnical Characteristics Of Ikole Soil In Ikole Ekiti, Ekiti State Nigeria

ABSTRACT This piece of research work will analyze the type of geotechnical properties of Ekiti state soil and the study area in lkole Ekiti local government area. Samples of soil were obtained at some location within the study area and it will carried to laboratory for some test. This project work will involve sample collection, sample preparation and detailed laboratory analysis on the geotechnical and properties of the collected samples. The geotechnical analysis of the research deals...

Spatial Distribution Of Runoff In Ungauged Catchments In Tanzania

Abstract This paper presents a preliminary map of average annual runoff of Tanzania using a conceptual rainfall runoff model to predict the amount of water directed to base flow of the rivers with the application of Geographic Information System (GIS). Average annual runoff is a fundamental hydrological variable which serves many purposes in hydrological research particularly in stream flow estimation for hydropower plant allocation and development. Still the runoff data can serve during irri...

Design And Construction Of A Simple Burglar Alarm System

ABSTRACT This work present the design, construction and testing of a simple burglar alarmactivated by light, break beam and pressure sensor. The principle of operation of this burglar alarm is simple. When the ray of light  falls on the light sensor the alarm is triggered and the siren begins to operate, the speaker beeps and the flasher (light) flashes. When an intruder walks  through the  break beam sensor the alarm is triggered and the siren begins to operate, the  speaker beeps and...

Performance Analysis Of Zigbee/Ieee 802.15.4 Standard For Wireless Body Area Network

ABSTRACT Recently, in most of the developing countries like Tanzania, life expectancy and the inherent costs of caring for an aging population are increasing. These have put an enormous demand on the health care systems and have driven the advancement of technology-based sensor devices that can remotely monitor key vital life signs. These advancements enabled proliferation of wireless sensor networks. These sensor networks are capable of monitoring and controlling environments remotely, ther...

Performance Evaluation Of Handover Scenarios In Mobile Wimax Networks

ABSTRACT Achieving seamless homogeneous handover in mobile WiMAX due to its low cost and state of the art technology will enable ubiquitous broadband access to high volume applications especially with the high global increase in mobile subscribers. Extending this seamless handover across network technologies-heterogeneous handover- like WiFi will further lower cost, improve battery life and enable high productivity for end users. In this project, ways of optimizing handover in mobile WiMAX n...

Integrated Solar And Hydraulic Jump Enhanced Waste Stabilization Pond

ABSTRACT This study on the integrated solar and hydraulic jump enhanced waste stabilization pond (ISHJEWSP) is aimed at determining the effect of variations in solar radiation, hydraulic jump, hydro-kinematic factors and pond geometry, on the treatment efficiency of wastewater in the ISHJEWSP. An equation to account for these effects was derived, calibrated and verified. An empirical regression model for the prediction of the Biochemical Oxygen Demand (BOD5) in the ISHJEWSP for sewage treatm...

Sms-Based Information Search And Retrieval System

ABSTRACT This thesis “Short Messaging System(SMS) Based Information Search and Retrieval System” describes a technology facility that will enable local information to be collected and put in a repository system (Database) such that a mobile user using the facility will be able to search for such information from any location where Global System for Mobile Communications(GSM) services are available. The work concentrates on developing the server-side program that will run as the search pro...

Estimation Of Biogas Reactor Constants Using Multiple Regression Analysis

ABSTRACT Biogas generation is accomplished by anaerobic digestion of biodegradable material in a biogas digester. Anaerobic digestion as a process requires dynamic model for predicting process performance. Mathematical model for biogas production from anaerobic digesters described in this study was used to predict biogas generation using experimental data. Multiple regression analysis was used in analyzing two sets of data, the first sets of data contains four different experimental results ...

Development Of Jos Tv Broadcasting Studio Reliability Model

ABSTRACT The broadcasting stations in Nigeria often encounter sudden failures, which results in loss of signal that causes the station to experience down-time. Causes of the failures could be traced to the issues that range from erratic power supply to degradation in the studio equipment. Each failure and its consequent down-time influences the reliability of the station. In our environment (Nigeria) reliability does not only depend on the established parameters, instead it includes paramete...
