This paper is a detailed study of IoT devices and effectively using them for Energy Management at our Homes. IoT Energy Management is an operation that involves organizing and administration of energy consumption patterns in numerous industries. As a part of the Smart System, Home Energy Management System (HEMS) is becoming increasingly essential, because energy consumption of urban residential sector accounts for a noteworthy amount of total energy consumption. However, a conventional HEMS h...
ABSTRACT. To achieve most accurate coverage area results during installations of sector antennas, the technical team must create a coverage map for each of the sectors basing on the provided coverage values. The technical team uses these values to make manual position adjustments of sector antennas. Manual antenna adjustments are sometimes risky in a way that unexpected accidents usually occur that even result into death. To overcome such scenarios, an android based sector Antenna positioni...
CHAPTER ONE: INTRODUCTION 1.1 Background Uganda has got many Small and Medium Sized Contractors (SMSC) engaged in the construction business. Some of these (SMSC) change business name and scope within a short time because of the competitiveness pressures within the construction industry. Little is achieved by these struggling SMSC due to the level of development of the local construction industry (LCI). Recent studies show that the Local Construction Industry is not very competitive, undeve...
ABSTRACT This study presents the derivation of polynomial functions for the prediction of critical axial forces in bridge trusses. Four different bridge trusses were considered in this study, three of which are statically determinate while one is statically indeterminate. These trusses at different height to span (aspect) ratios were tested for critical axial forces under the same conditions. The graphs of their critical axial forces against aspect ratios were plotted and this led to the find...
ABSTRACT This study investigated the structural characteristics of chikoko mud-cement concrete. The structural characteristics of chikoko mud-cement concrete investigated were compressive strength, flexural strength, shear strength and split tensile strength while the elastic properties investigated were static modulus of elasticity, poisson’s ratio and shear modulus. The water absorption of chikoko mud-cement concrete as a reflection of concrete durability was also investigated. Ninety (9...
ABSTRACT This work investigates the optical properties of glass prepared using Otamiri Silica sand mixed with analytical grade oxides as a function of their composition. Three batches were prepared with Phosphorus as the main variable of the SiO2-Na2OB2O3-CaO-ZnO glass system. The glass was melted in a ceramic crucible with a lid and the glasses melted after two hours of firing in a monolithic charcoal furnace. The effect of varying SiO2 and P2O5 on optical properties was determined using a ...
ABSTRACT Development and performance analysis of compressed natural gas (CNG) as a transportation fuel for automobiles in Nigeria are presented. The study involved compositional analysis of natural gas obtained from the product sales point at a treatment plant about 10km off the Port Harcourt-Onitsha route chosen to ensure standard sales gas specifications, design of the gas pipeline network and the refuelling stations requirement and locations. Using field investigations and developed physi...
ABSTRACT This study developed computer software with the capacity to provide a generalized solution to queuing problems involving laborious, time consuming and complex mathematical approach of evaluating the performance measures of queuing systems when it was applied in the analysis of the six (6) fundamental performance measures of thirty (30) different organizations representing the six (6) queuing systems; the result was compared with that of mathematical computations and 97.22% complianc...
ABSTRACT The proposed Access Roads which will connect the Airport Road to the main gate of the African University of Science and Technology, Abuja, Nigeria and the proposed Bridge Housing Estate when constructed will foster broader community goals by promoting business activities within and around the University environment. Topographic data were taken, traffic study and traffic volume forecast where carried out; minimum curve radii and curve lengths were calculated The traffic study for the...
ABSTRACT The analysis of macro and trace elements in selected snacks available in the Federal Capital Territory (FCT), Nigeria showed varied concentrations of the essential elements (Fe, Cu, Ni, Zn, Mg, Ca, K, Na, Mn, Cr) and non-essential elements (Pb, Cd, Hg, Co) in the fifteen different samples (Meat-pie, Bread, Cake, Doughnut, Scotched egg, Sausage, Samosa, Spring Roll, Scones, Egg Roll, Akara, Buns, Okpa, Fish Roll, Chicken pie) analyzed. Potassium and Sodium were determined using Flam...
ABSTRACT This research work presents the static analysis of short cylindrical shell under internal liquid pressure with various boundary conditions and aspect ratios. Improved fourth order finite difference method was employed for the analysis and a MATLAB computer program was developed based on the matrix equations and models generated from the analysis. The following boundary conditions were covered in this research; short circular cylindrical shell simply supported at both edges(s-s), sho...
ABSTRACT Equal channel angular pressing (ECAP) has over the years been used as a severe plastic deformation method to refine the grains and improve the strength of various metals. Even though this has been largely successful, research over the years has tried to increase the amount of strain induced in the materials used during this process so as to further increase the strength. In this research, an additional 30o twist angle was incorporated into the outlet channel of one of the ECAP dies ...
ABSTRACT Electrochemical capacitors (ECs) or Super capacitors (SCs) are energy saving devices which have excellent properties that include high power density, long cycle life, low temperature sensitivity and low maintenance cost. However, these devices have lower energy densities than conventional batteries. To improve on its energy density, SnO2 which is a metal oxide was considered as an electrode material because of its chemical inertness and thermal stability. SnO2 nanoparticles were syn...
Primarily, the team will attempt to develop the application that the user can use it to monitor the daily energy consumption in their home. The application could generate reports data dividing by quarter or week to help users understand the source of specific energy consumption, thereby helping users save the cost of energy and protect the environment. The “big picture” of the business and the application creates an environment that enables people to live up to the values we seek to ...
The Engineering Characterization of Agbani clay deposits has been investigated with a view of finding its usefulness in the engineering industry and home. The chemical analysis was carried out using X-ray fluorescence (XRF). Physical properties tests such as apparent density, apparent porosity, water absorption, shrinkage, modulus of rupture, bulk density, moisture content, conductivity, thermal shock resistance and specific gravity were all carried out using international accepted standa...
