Projecting changes of maize yield based on regional weather parameters using Artificial Neural Network
Maize is one of the largest food crop cultivated in Mubi region. It is produced annually and serves as the source of food and revenue. This work developed, an artificial neural network (ANN) model based on the data collected to forecast Maize yield in terms of weather parameters (Temperature and Rainfall). Predicted yield increased by 0.37 tons, 0.67 tons, 289.48tons and 0.17 tons in 2006, 2011, 2014 and 2015 and reduced by 0.52 tons, 0.32 tons, 5.53 tons, 15.44 tons, 0.45 tons and 0.25 tons ...
Assessing the influence of weather parameters
Rain serves as one of the key components in water cycle and it comes in the form of water droplets that are condensed from atmosphere and then fall on earth surface as rainfall. It has much importance. However, excessive rainfall can cause environmental hazards. This work developed an adaptive neuro – fuzzy inference system (ANFIS) to relate certain weather parameters (temperature and relative humidity) with rainfall in order to forecast the amount of rainfall capable of causing River Yazar...
Design and construction of an automatic Battery charger
ABSTRACTThis project describes the design and construction of an automatic Battery charger. Automatic Battery chargers are not particularly cheap, but the protection they afford in protecting batteries against overcharging and possible battery damage is highly desirable. However the work carried out through the construction and design of an inexpensive alternative to the commercially available fully Automati...
Quantum Gravity in a Nutshell 1
This math-free book is a good introduction to quantum gravity and has a lot of interesting history about the development of the theory since 1899. It's an informal introduction to a very difficult and doubtfully intelligible theory.- doubted even by its most ingenious contributors. The reader should expect that he/she will have to concentrate hard on what Balungi says but the rewards are significant. He is a talented physicist and a good writer. If you read it carefully and st...
Estimation of Global Solar Radiation Flux Over Ibadan
Renewable energy resources are those having a cycling time less than 100 years and are renewed by the nature and their supply exceeds the rate of consumption. Renewable energy systems use resources that are constantly replaced in nature and are usually less polluting. This project work estimates the solar radiation flux over Ibadan, a south-western city in Nigeria. The estimated models for the solar radiation over Ibadan are obtained for the period of ten years (1995 to 2004). The solar radia...
Indoor Gamma Dose Rate Exposure Levels in the Faculty of Science, University of Ibadan
Building materials are one of the potential sources of indoor radioactivity because of the naturally occuring radionuclides in them. Exposure to indoor ionizing radiation, like gamma radiation, results in critical health challenges. This work was designed to assess the indoor gamma dose rate level following the renovations of offices of lecturers in Faculty of Science, University of Ibadan using RDS-30 Survey meter. Measurements were made at 110 locations after renovations and in some selecte...
Performance of Ionex Map at Ilorin
Ionosphere is the region in the upper atmosphere where there are sufficient amount of electrons and ions to influence the propagation of radio wave. For radio wave propagation studies and application, a standard model (model based on data) such as IONEX map model was developed to study the ionospheric parameter i.e. the Total Electron Content. This parameter is used to quantify the level of ionization in the ionosphere. The performance of IONEX map model over Ilorin with station coordina...
Preliminary structural evaluation of an X-Field Onshore in Niger Delta using 3D seismic data
Preliminary structural evaluation of an X-Field Onshore in Niger Delta using 3D seismic dataA structural evaluation of a post stack time migrated (PSTM) 3D seismic data over an X–Field in the eastern Niger Delta has been attempted. The objective of the study is to structurally evaluate the field with a view to identifying structural features such as faults, map geologic horizons and analyze reflection characteristics that might be a good lead to probable hydrocarbon accumulations. Results r...
DESIGNING AN EQUISPACED LEVEL QUANTUM WELL IN THE ULTRA TIN LAYER OF A SEMI CONDUCTOR ALLOY
ABSTRACTA derivation of equispaced-level conduction band Hamiltonians using the coordinate-transform based procedure is presented. The procedure start with the effective-mass schrodinger equation (Luttinger and Kohn, 1995), where the local conduction-band edge is interpreted as the potential experienced by and electron in a quantum well (QW). The electron effective mass variation is proportional to the potential variation within the a QW, and the well has equispaced bound state.In sem...
DIGGING A HOLE STRAIGHT DOWN INTO THE EARTH (What will happen)
ABSTRACT: The earth has three layers each consisting solid materials that make them hard and difficult to be penetrated. But, suppose we neglect every other hindrances, where do we expect to go when we dig straight down through the earth passing through all the layers. This paper explains all about what is experienced and the Scientific analysis when/if the earth where to be dug through.
1-D Time Dependent Schrodinger Equation (Simplest derivation) - Alfred Dambe Enu
ABSTRACT: Deriving Schrodinger equation has always been with students. This paper made it easy to students by analysing the steps involve in deriving the equation in the simplest manner. This is the easiest way to derive, understand and to define the meaning of the equation.
Principles of Friction and Viscosity. By Alfred Dambe Enu
ABSTRACT: Friction and Viscosity are very strong concepts in Physics and Engineering. This paper discusses some basic aspects of these topics and their application in daily natural phenomena.
Bohrs Radius of the Atom
ABSTRACT: Students always ask the question, if there is such a strong electrostatic force of attraction between the nucleus and electrons at the lowest orbital as proposed by Bohr, how then does the electron orbit the nucleus without collapsing into it. This paper answers that question base on Neils Bohr's assumptions. The paper derives the speed of electrons on their orbits with respect to their orbital radius. This paper also explains why electrons at the higher orbital revolves the orbit a...
Investigation of thermophysical properties of alates (swarmers) termite wing as potential raw material for insulation
Thermo physical properties of Alates (Swarmers) termite wing has been investigated. The result of our investigation shows the values of thermo physical parameters of the sample materials as 0.0403Wm-1K-1 being the mean thermal conductivity value, bulk density of 188. 8kgm-3 and thermal diffusively value being 8.2485 x 10-8m2s-1. The values are within the values for commonly used insulating materials. Comparing the rate of cooling as well as heat absorption into the material as lagging materia...
