ABSTRACT This project work covers the design and construction of a robotic arm mechanically capable of 5 Degrees of Freedom. It solves the problem of automatically detecting and picking up objects placed within distances of 10-30cm round the robot base platform. It does this by using a simplified forward and inverse kinematic relation modeled in two dimensional robot workspace. The work does not cover the more general case, of an n-linked (n>2) robotic arm working within a three dimensional...
ABSTRACT This project presents a 40A maximum power point tracking solar charge controller. The MPPT charge controller tries to keep the voltage and the power stable. The MPPT charge controller will harvest more power from the solar array – it will adjust its input voltage to harvest the maximum power from the solar array and then transform this power to supply the varying voltage requirement of the battery plus load. An MPPT charge controller is an electronic DC to DC converter that optimi...
ABSTRACT The problem of epileptic power supply and its consequences in the developing countries is a generally known issue. Worst still, the hope that it will be addressed with the deregulation of electricity Industries in recent time are being dashed by flight to top class investors due to its poor implementation. There is a need to provide multiple sources of power and automatic mechanisms for switching from one source to another. This is achieved in this work where quadruple power supp...
ABSTRACT This paper presents an electronic Expert system platform to detect and diagnose existing and new cases of contagious diseases as they occur with minimal contact with the index patient(s) and healthcare personnel with a confidence level that can be used to initiate or suggest appropriate follow-up action(s). The aim is to use ICT tools for patient-diagnosis, raise a red flag in real-time and thus contain contagious cases which may degenerate into an epidemic by providing a way to ana...
ABSTRACT The inhibitive strength of Canonamuricata (CM) and Cassuttidfilifurmis (CF) on mild steel dissolution in 0.5 M H 2 SO 4 and 1 M HCl environment was studied using gravimetric and electrochemical techniques. The results obtained indicate that all studied extracts of both plants are adsorption type inhibitors hence; t he adsorption of the inhibitors is in line with Langmuir adsorption isotherm. Efficiencies of the inhibitors increased with an increase in concentration of the extract but...
ABSTRACT This study presents the modelling and optimization of a Hybrid Energy System (HES) for GSM Base Transceiver Station (BTS) sites in emerging cities. The aim is to ensure reliable and cost-effective power supply, considering the availability, dynamism and viability of energy sources. Theoretical approach is applied in the modelling, simulation and validation of the developed HES, which consists of the utility grid, wind and solar photovoltaic (PV) as primary energy sources incorporati...
Abstract- This study investigated the parameters space of simple and familiar quadratic equation often encounter in science based disciplines and in particular engineering. The aim is strange images creation to excite and launch novices to quest for general understanding of fractal taking parallel clue from Julia and Mandelbrot sets creation using the iterative mechanism of complex quadratic mapping. Preliminary computation of a Julia and Mandelbrot sets was performed on a square complex plan...
Abstract—In recent years, chaotic secure communication systems have attracted significant interest due to their higher unpredictability over conventional secure communications systems and simplicity of implementation. This study presents the modeling of four chaotic modulation techniques. The techniques are Chaotic Masking (CM), Chaos Shift Keying (CSK), Chaos On-Off Keying (COOK), and Differential Chaos Shift Keying (DCSK). Simulations were carried out using Simulink in Matlab environment ...
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 Imagine a five-year-old boy losing his life by being knocked down by a drunk driver who has been intoxicated with alcohol. The driver’s carelessness will cause the family of the little child so much pain, as well as lead to a significant loss of human resources in the country. Road accident according to research has been the second leading cause of death in Ghana. While several countries in the world invest in finding solutions to road accidents [1], little is done by the country t...
ABSTRACT PV modules exhibit a point at which its power is maximum; this point is called Maximum Power Point (MPP). Due to changes in weather conditions, the MPP changes and the PV module efficiency. Specifically, temperature and irradiance are the parameters that affect the solar panel characteristic properties. This project describes and implements an MPPT algorithm that tracks the MPP at every point in time depending on the load. The algorithm was modeled using MATLAB Simulink and tested un...
Abstract The Ghanaian transit system poses certain challenges to users, as it usually has passengers waiting at bus stops for a bus to their destination, for an unknown amount of time because there is no means of tracking the buses. The system is also problematic as passengers usually argue with bus conductors for change, when payments are made in high denominations, because there are no cashless payment methods available. This makes planning of journeys difficult to users of this system. Exi...
ABSTRACT An electronic component is an entity in a system which can not further sub-divided in the course of a given reliability.
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,...
