THE EFFECTS OF MOISTURE AND FERMENTATION PERIODS ON THE PHYSICAL AND BIOCHEMICAL PROPERTIES OF ‘AMELONADO’ AND ‘HYBRID’ VARIETIES OF COCOA BEANS

ABSTRACT The effect of moisture content (5-24%) on some physical and compressive properties of the ‘Amelonado’ and ‘Hybrid’ varieties of cocoa beans were studied. Alongside, the effects of fermentation periods (0-8 days) on the biochemical profiles of the dried beans were studied in three morphological parts (whole bean, nib and shell). Four experiments were separately conducted as completely randomized, factorial designs. Compared to the ‘Amelonado’ variety, the axial dimension...

ASSESSMENT OF POTENTIAL IMPACT OF CLIMATE CHANGE ON PEANUT YIELD IN SENEGAL THROUGH A MODELLING APPROACH

ABSTRACT This study assess of the potential impact of climate change on peanut yield in Senegal. Seven field experiments were conducted at three sites in the dry seasons of 2014 and 2015 and the rainy season of 2014. SIMPLACE1 crop model was calibration and validation at two sites Bambey and Nioro and for two peanut cultivars over two years. To assess the impact of climate change on peanut growth and yield in Senegal, outputs of four Regional Climate Models were used together accounting for ...

THE DESIGN OF A LOWCOST AUTOMATIC GROUND VEHICLE FOR WAREHOUSE STOCK MANAGEMENT

Abstract In this project the design of an automatic ground vehicle for use in warehouses is explained. Ecommerce has been growing rapidly across the globe because of the spread of the internet and due to the introduction and acceptance of secure digital payment systems. Volumes of products handled by online stores has been increasing exponentially because of increased demand. This has resulted in a need for online shops to automate some of their processes in order to make logistics more effic...

INTELLIGENT WIND TUNNEL DESIGN

Abstract A Wind tunnel is a mechanical assembly used to analyze the behavior of air flow and the effects they have over objects. Using a wind tunnel, one can control the stream conditions which influence forces on the test object. Through the calculations of the forces on the model, one can anticipate the forces on the full-scale test object. In the beginning, wind tunnels were used to utilized to comprehend and improve the execution of airplanes. Over the years, cars, bridges, and building w...

ANAEROBIC DIGESTION OF SHEA WASTE FOR ENERGY GENERATION

ABSTRACT In search for an alternative source of energy and also in order to utilize the shea waste in an appropriate way and to reduce its negative impact on the environment, the waste was investigated to identify its potential in methane generation through anaerobic digestion. The basic raw materials for the study were shea waste and cow dung. Input substrates were prepared with addition of predetermined amounts of water to bring the substrates to the required organic dry matter (odm) conc...

A CHEAP AND PORTABLE WIRELESS INCUBATOR FOR PREMATURE BABIES

Abstract The leading cause of child mortality globally is prematurity. These deaths mostly occur due to unavailable or high cost of keeping babies in clinical incubators, which provide controlled environment for premature neonates. The aim of this project is to develop a cheap and portable wireless incubator for premature babies. The project focuses on reducing the causes of preterm death and, as such, incorporates measures to minimize such factors. Hence, the incubator’s other functions ar...

PRODUCTION OF CORRUGATED ROOFING SHEETS FROM EPOXY-BASED MATRIX REINFORCED WITH TREATED COIR FIBERS

Abstract Green roofing is a relatively new approach toward constructing environmentally friendly and sustainable roofing structures. Not only are these structures environmentally friendly, but they can be manipulated for the purposes of energy harvesting, thermal insulation or cooling while saving cost in the long run. Much like the green roof approach, this project seeks to create, for an African setting, with a case study in Ghana, a less costly alternative to durable roofing options such a...

DESIGN AND FABRICATION OF AN INFLATABLE WING

Abstract This project paper explains the design and fabrication of an inflatable wing using a flexible, low cost and easily accessible PVC material. In recent times, several researchers have explored the building of inflatable structures using expensive and high strength materials like Mylar and Kevlar. However, this project scope was contextualized in the East African region where there is need for flexible and low cost Unmanned Aerial Vehicles (UAVs) for applications such as military survei...

PRIVACY-BY-DESIGN FOR INTERNET OF THINGS(IOT): IMPLEMENTING USER AUTONOMOUS OPTIONS IN A SMART HOME SCENARIO

Abstract In traditional Internet of Things (IoT) systems, users are unable to authorize and/or deauthorize the collection of user data. Hence, the problem of the absence of user autonomy in IoT systems. The project aims to tackle this problem by suggesting a human-centered privacy-by-design option in the design and implementation of IoT systems. It aims to prioritize the need for the privacy of the user in designing IoT systems. It proposes to do this through the provision of user autonomous ...

Rodin Platform Why3 plug-in

Abstract. We briefly present the motivation, architecture and usage experience as well as proof statistics for a new Rodin Platform proof back-end based on the Why3 umbrella prover. Why3 offers a simple and versatile notation as a common interface to a large number of automated provers including all the leading SMT-LIB and TPTP compliant tools. The plug-in can function either in a local mode when all the provers are installed locally, or remotely as a cloud service. We discuss the experience ...

COMPUTER AIDED HYDROPONICS WITH REINFORCEMENT LEARNING

Abstract Hydroponics, a system of growing crops without soil, has been successfully used to grow crops on a commercial scale. Hydroponics has the potential to fill the gap of low agricultural production in Ghana due to its high efficiency while serving as an environmentally friendly alternative to soil culture. This method of farming has benefitted from new technologies like IoT and machine learning that make it possible to integrate intelligent agents in the management of hydroponic systems ...

A LOW COST IoT SYSTEM FOR MONITORING FUEL TANK CONDITIONS

Abstract Following the discovery of Oil in Ghana the upstream industry of the Oil and Gas has received a jumpstart and is augmenting the older and more established midstream and downstream industry. The midstream and downstream industries involve the processes that refine, transport, and distribute oil and other crude products and as economic activities increase there is an urgent need to vamp up production, and this can be done by increasing the efficiency of storage processes. This paper ex...

BUILDING A LOW-COST BIOMEDICAL DEVICE TO IMPROVE ACCURACY IN PNEUMONIA DIAGNOSIS IN UNDER FIVE CHILDREN

Abstract Pneumonia has been the leading cause of death among children under the age of five in subSaharan Africa, killing more children than the number of children dying from HIV/AIDS. The current methods of diagnosing pneumonia are limited by poor sensitivity and accuracy and they are also expensive. In this project, a low-cost biomedical device was designed and developed to improve the accuracy in diagnosing pneumonia hence assisting in correct prescription of drugs to children. Sounds wave...

LOW COST VEHICLE DRIVING ASSISTANCE SYSTEM

Abstract The project intends to increase vehicle operator awareness with the integration of a Low-Cost Driving Assistance system in older car models. Situational awareness during driving significantly reduces the number of road traffic accidents, as proved by literature. A 4-wheel mobile robot is used as the plant representing a vehicle for easier and rapid prototyping. The plant is controlled by a Raspberry Pi3 to achieve the desired control choice as well as do all required computational pr...

A LOW COST ANTI-THEFT TRACKING SYSTEM FOR ELECTRIC VEHICLES

ABSTRACT A vehicle tracking system is any technology that can be used to access the location of a vehicle; either in real time or offline. However, for many car owners, especially on the continent of Africa, vehicle tracking is a luxury which only a few people can afford. Many people are struggling to get a car in the first place. Analysis of vehicle theft data done in South Africa showed that most of the vehicle theft in the Southern African country are as a result of poor security systems. ...
