Comparative analysis of internet performance over 3 sites with and without VPN

   ABSTRACTNowadays, there is an increase in the demand to connect to the internal networks of organizations by their branches from distant locations. Members of such organizations often need to access internal networks from their homes, hotels or other far away business places and external networks over the internet which is insecure by virtue of its public nature.The security of information transferred in the network becomes a major challenge when staff or partners in business acc...

THE DESIGN AND IMPLEMENTATION OF RADIO FREQUENCY COMMUNICATION LINK

ABSTRACTThe aim of this project, the design and implementation of an RF communication link, is to design a communication link between a source and a destination and study the properties of the signal being generated by the source (generator). The area of interest in this work is how the signal suffers limitations like attenuation, interference and distortion etc and to observe how these limitations affect the smooth transmission of the signal as well as the amplitude of the transmitted...

INVESTIGATION ON HEAT DISSIPATING PROPERTIES OF ELECTRONIC COMPONENTS WITH THE AIM TO DETERMINE THE CORRECT SIZE OF HEAT SINK

Research and optimization of cooling of electronic components using heat sinks becomes increasingly important in modern industry. Numerical methods with experimental real world verification are the main tools to evaluate efficiency of heat sinks or heat sink systems. In this research, the physical problems associated with heat removal of electronic systems at different scales were studied.ABSTRACT Research and optimization of cooling of electronic components using heat sinks becomes incr...

DESIGN AND CONSTRUCTION OF A FAN SPEED CONTROL SYSTEM

                       AbstractThis temperature control fan can be controlled using a microcontroller when it detects acertain temperature that has been set. The purpose of this project is to prevent the waste ofvoltage usage when it is not hot enough for fan to be needed. The temperature control fanhas three different speeds. Each speed will change according to a certain level of temperaturethat is set. This project is a combination...

DESIGN AND CONSTRUCTION OF ELECTRICAL CODED DOOR LOCK SYSTEM

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 ...

DESIGN AND CONSTRUCTION OF A SOLAR POWERED MULTIPLE CELL PHONES CHARGING BOOTH

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...

CONSTRUCTION OF A 2.8KVA FUEL-LESS GENERATOR

Abstract In 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...
