ABSTRACTWhenever we think of redefined security, we think of coded electrical
door lock. It is a microcontroller based security door lock that can be used in
homes, offices, laboratories, etc. for more reliable and high fidelity door
control system, powered by electrons panel or electromechanical panels. Due to
high rate of insecurity, especially intrusion into homes and offices, this
project provides the users with an electronic keypad to enter the password
required to get access into ...
ABSTRACTCell phones need electric sources to charge their batteries in
order to work, but there are people in developing and third world countries
that find it hard to access electric sources.In an attempt to provide an
alternative means of charging to those unfortunate areas in third world and
developing countries, a solar powered cell phone charging booth is to be
designed and constructed in this project.The goal of this project is
to create a multiple output solar cell phone chargers...
this work, a 2.8kva alternator was coupled to a 4 H.P dc motor acting as a
prime mover to produce a fuel-less generator. The coupling was done using two
crankshaft pulleys to match the speed of the alternator to that of the dc
motor. Two 24v dc deep cycle batteries were also used as the exciter unit and a
sustainable output voltage of 232V was achieved. TABLE OF CONTENTSTitle PageDeclarationCertification. iiiDedication. ivAcknowledgement. vTable Of Contents. viLis...
In other for a
business/firm to get the best out of its employees and a high return on its
investment in people, the human resources must be well managed. A good human
resource management system brings consistency in human resource management
practices and improves human relations in the company thereby enhancing
individual/organizational effectiveness. With larger firms/organizations, it
becomes increasingly difficult to manage a large number of human resources.
