ABSTRACT The frequent occurrence of fire accidents in commercial complexes has become a serious problem in Nigeria. The development of a quantitative tool for evaluating the proneness of a commercial complex to so called 'market fires' is the focus of this study. A rigorous review of the literature was carried to identify and characterize some existing risk analysis models applicable to the problem. Some past fire disasters were analyzed. Using the insight gained from the above, a mathematica...
ABSTRACT This paper applies the concept of Hybrid Structural Interaction Matrix (IISIM) to the management of quality in a manufacturing organisation. 111e application is motivated by the need 10 evolve alternative prioritisation tools in quality management. A process, which could be used to analyse a specific situation, was presented by showing how Structural Interaction Matrix (SIM) and Hierarchical Tree Structure Diagram (lITSD) could be used 10 create a model. The result indicates the feas...
ABSTRACT Energy study was conducted in an organic fertilizer plant in Ibadan, Nigeria, to determine the energy requirement for production of both powdered and pelletised organic fertilizer. The energy consumption patterns of the unit operations were evaluated for production of 9,000 kg of the finished products. The analysis revealed that eight and nine defined unit operations were required for the production of powder and pellets, respectively. The electrical and manual energy required for t...
ABSTRACT There is much concern about the fossil fuel exhaustion and the environmental problems associated with conventional power generation. PV systems are the most direct way to convert solar radiation into electricity and are based on the PV effect, which was first observed by Henri Becquerel in 1839. It is quite generally defined as the emergence of an electric voltage between two electrodes attached to a solid or liquid system upon shining light onto this system. Practically, a...
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...
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 ...
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...
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...
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...
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...
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...
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...
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 ...
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 ...
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 ...
