ABSTRACT An easy-to-use and accurate multi-frequency path loss model is a necessary tool for heterogeneous radio network planning and optimization towards achieving a smart campus. The learning ability in artificial intelligence may be exploited to reduce computational complexity and to improve prediction accuracy. In this research project, an optimal heterogeneous model was developed for path loss predictions in a typical university campus propagation environment using machine learning appr...
ABSTRACT This paper deals with the measurement of dielectric properties of some local cereals (com, beans, rice) in the audio frequency range (0.3- 20KHz) since dielectric properties of various agrofoods and biological materials are finding increasing applications, as fast and new technologies adapt/adopt these cereals for use in their respective industries and research laboratories. A Marconi instrument, 0.1% universal impedance bridge together with a specially designed and constructed coax...
ABSTRACT Biometrics is a physical, electronic and biological means of providing dependable and accurate identification of people. It entails data acquisition, storage and subsequent matching at points of access or identification. Biometrics is an emerging technology that identifies people by their physical and/or behavioral characteristics and practically requires the person to be identified to be physically present at the point of identification. In this thesis, efforts to improve biometric...
ABSTRACT Cloud computing has not only emerged as an accepted computing paradigm, but is fast penetrating into major sectors of human endeavor. These include banking, human resources management, justice administration, investigation, academia/research, commerce, health administration etc. Based on the public and experts concerns about cloud applications in the mentioned sectors, preliminary investigations were carried out and it was found that security, and in particular, authenticating...
ABSTRACT This research work undertakes the development of water pumping system (with emphasis on Irrigation) that is capable of automatically managing water budgets from a reservoir through a microcontroller subsystem. The water pumping for irrigation system can be used in gardens, farms, urban/rural water supply systems, and in fact, general water management systems for both domestic and industrial applications. The key objective of this research is to develop a user-friendly and efficient ...
ABSTRACT Cardiotocogram based monitoring needs a reliable fuzzy logic system to reduce the incidence of unnecessary medical intervention and fetal injury during child labour, due to a high degree of uncertainty and imprecision. Presently, electronic fetal monitoring is based almost entirely on the Cardiotocogram (CTG), which is a continuous display of the fetal heart rate (FHR) pattern together with the contraction of the womb. Despite the widespread use of the Cardiotocogram, it has li...
ABSTRACT This research work on “Modelling and Simulation of Leakage-Induced Pressure drops along oil and gas pipelines tends to develop flow equations that can detect and localize leakages in oil and gas pipelines by modifying the Darcy-weisbach equation for liquid/oil flow, and the Panhandle B equation for natural gas flow in pipelines. These modified equations were simulated using matlab to show how flow rate values for the oil and gas pipelines vary when; the pipeline is working at full ...
Abstract: The introduction of Non-Transmittable Codewords (NTCs) into Viterbi Algorithm Decoder has emerged as one of the best ways of improving performance of the Viterbi Algorithm Decoder. However, the performance has been tested only in hard decision Viterbi Decoder in telecommunication systems, but not in soft decision Viterbi Decoder and storage media. Most storage media use Reed Solomon (RS) Algorithm Decoder. Yet, the field experience still shows failure of the algorithm in correcting ...
Abstract: This paper presents a survey of recent development in Fault Localisation and Service Restoration (FLSR) following electrical disturbance in Power Distribution Systems (PDS) based on distributed approaches. Distributed approaches have been found to fit well in the distribution systems as they have more than one decisionmaking component, and data processing can be done in parallel in individual units that makes it faster and requires less processing capabilities centrally. Recently re...
ABSTRACT Power line fluctuations and cut-offs in electrical installations causes damages to electrical appliances connected to the line. It is may be more fatal in the case of domestic appliances such as fridge and other sophisticated appliances like TV sets, DVD players, computers etc. If a fridge is operated on low voltage, excessive current flows through the motor, which heats up, and get damaged. It can be used to protect the whole installation from undesirable over and under line voltage...
ABSTRACT The main objective of the study was to examine the challenges students face for not being allowed to use mobile phone in school with particular reference to Dabokpa Technical Institute in the Tamale Metropolis in the Northern Region of Ghana. The researcher used descriptive research design for the study. The sample size for the study was 185 samples made up of 150 students, 15 teachers, and 10 workshop assistants all from the school and 10 GES personnel from the Regional Directorate,...
ABSTRACT The self-running pulse charger was designed and constructed using solid-state devices to produce pulse current for charging lead acid batteries. The aim of this research is to reduce the use of kerosene lanterns by rural dwellers and aid pupils to study at night in off-grid communities which do not have electricity. A coil of 200 turns, MJ11016 FET, NE555 IC and various values of resistors, capacitors and diodes were soldered on a printed circuit board (PCB) to ensure proper e...
ABSTRACT The main purpose of the study was to investigate into the impact of using CFL bulbs on energy consumption in Ghana- a case study of Twifo Hemang lower Denkyira district in the central region of Ghana. This study employed quantitative and descriptive methodology to collect data and analyze data. The population for this study comprises individuals who consume electricity in the Twifo Hemang lower Denkyira District in the Central Region of Ghana. The population for the study was...
ABSTRACT Market-driven economies and deregulated electricity industry environments have stimulated minimization of the distribution losses even though they do not constitute major operational or quality of supply problems. This research discusses a method for evaluation of distribution losses and an effective management approach to loss minimization and revenue collection. In this research the contribution of other authors was sought on the distribution losses, their analysis and the va...
