Comparative Analysis of Practical Skills Acquisition in Electrical/Electronic Engineering Training Program in Accra and Kumasi Polytechnics in Ghana.

This research was designed to comparatively analyze practical skills acquisition in the Electrical/Electronic Engineering department in Accra and Kumasi Polytechnics. The study population was made of 578 students in the Department of Electrical/Electronic Engineering from the two study institutions respectively. A sample size of 25% was randomly selected from the total population. A total number of 145 questionnaires were distributed and 123 completed questionnaires were received makin...

Mixed H_2/H_∞ and Robust Predictive to Control Wheeled Mobile Robots with Time Delay

The purpose of this paper is to perform path tracking for a non-holonomic mobile robot subject to kinematic disturbances using model prediction and  H-2/H-infinity control and by Gain-scheduled control law. In this method, the problem of tracking a mobile robot is expressed in such a someway that its kinematic error is in the form of linear parameter variable with bounded disturbance, the purpose of the design...

The Electrical Engineer And The Community A Clarion Call For Sensitivity And Long Term Investment

IntroductionThis paper considers the influence the electrical engineer wills in any community and aims at the following:(1) Sensitization of electrical engineers towards self sustenance(11) The electrical engineer as a job creator.(iii) the electrical engineer as an employer.(iv) The role of electrical engineers in the creation of cottage industries and long term investments. The paper hinges its arguments on the commercialization of ideas as a basis for sustenan...

Cadmium Chloride Thin Films: Hydration-Dehydration

ABSTRACTWe have been using polycrystalline thin films of anhydrous cadmium chloride (CdCI2) as an electron beam positive resist for the fabrication of features in SO2- coated silicon wafers The kinetics and mechanism of the electron-beam-induced decomposition of CdCI, which is the resist reaction, have been studied in details this work required that we know the thickness and density of the film. In the ordinary way of things, film thickness and density determination is a routine matter,...

Electron Beam Decomposition of CdCI2

ABSTRACT The e-beam stimulated reaction, CdCI2(s) ---> Cd (s) + CI(g), has been studied in casmium chloride thin films between 303 and 483 K using 2-keV electrons. The dose required to make 90-nm-deep holes at 483 K is 3x10-3 C cm -2. Extrapolated dosing levels of 6x10-5 C cm -2 are expected. The use of CdCI2 as a positive-type electron resist in a new scheme is proposed. A working model, useful for considering the e-beam stimulated decomposition energetics and mechanism is briefly ...

A Modified Linear Contribution Factor Model for Improvement of Reliability Indices of Electrical Distribution Systems

ABSTRACT In Nigeria, a satisfactory degree of reliability has not been attained in our power systems in recent times. The average duration of interruptions that customers experience is quite high and the degree varies from place to place. This is evident all around the nation, most especially in urban commercial cities. Previous researchers have focused on the assessment of power system reliability indices using different models. In this work, a computationally efficient modified linear ...

E BEAM INDUCED DECOMPOSITION OF INORGANIC SOLIDS

ABSTRACTA general model for the e-beam induced decomposition of covalent and ionic inorganic solids is outlined.

Optimal Location and Sizing of Distributed Generation in Distribution Network Using Adaptive Neuro-Fuzzy Logic Technique

The growing gap between electric power generated and that demanded is of utmost concern especially in developing economy, hence calling for measures to argument the existing power generated of which DG is a more viable aspect to explore in curtailing this challenges; although been confronted with issue of location and sizing. This research applied Adaptive neuro fuzzy logic technique to optimize DG location and size. A 24 bus radial network was used to demonstrate this process and having a su...

IMPACT OF WEATHER VARIABLES ON ELECTRICITY POWER DEMAND FORECAST USING FUZZY LOGIC TECHNIQUE

Fuzzy logic, being a very robust artificial intelligence technique, was employed to forecast short term load in this work. The algorithm was demonstrated with the help of seven months average daily load data collected from Power Holding Company of Nigeria (PHCN). The outcome realized from the model or simulation illustrate that the projected forecasting technique, which propose the use of weather alteration such as temperature and humidity, gives load forecasting results with substantial prec...

Assessing the Benefits and Challenges of Distributed Generation in Nigeria Power Distribution Network

The growing concern for the need to reduce the gap between power generated and power consumed in Nigeria is on the increase. Many measures and policy have been geared by Nigeria Electricity Regulatory Commission and Ministry of Power to revamp the generation aspect of the country power sector but the impact is yet to be felt as the amount of power still generated is far below par compared to other countries. Nigeria average power generation stands at an average of 5800 MW. With the call to...
