ABSTRACT This project is about the Design and Construction of a Vehicle Tracking and Accident Alert System (VTAA) using GPS and GSM Technology. It comprises of integration between GPS receiver, microcontroller and GSM module, and of course the push button for accident alert activation. The combination of all this technology wilJ produce our VTAA system. The GPS module receive the coordinate of the point at which the system is located, controlled by the user using command interfaces thro...
ABSTRACT The design of the wireless audio and video transmitter was done in stages taking into consideration a pre-selected desired frequency. These stages are the power supply stage, the carrier frequency generation stage, the carrier frequency pre-amplification stage, the voltage controlled oscillation stage and the final stage which is the modulation and amplification stage. First, carrier frequency was generated in the oscillator circuit comprising of an NPN transistor Cl 674, a vari...
Abstract Control system is integral part of modern society numerous applications are all around the whorled. The rockets live and the space shuttle lifts of the orbit in splashing cooling water, a malleable part is automatically machined a self guided vehicle delivering mechanical to work station in an a era space assembly planet glides along the floor speaking it’s destination. In modern industries the maintaining and handling of disturbance has a grate significance of efficiency and cost...
INTRODUCTION RADIO FUNDAMENTALS. Radio equipment are used for the transfer of information by electromagnetic means. A complete assembly of a radio circuit required to effect the desired transfer of Information is known as a telecommunication system. Common telecommunication systems include telegraphy, telephony, telemetry, television, radio etc. In general, the building block of wireless systems or otherwise include the transmitter, the channel and the receiver, The transmitter converts the...
The main drawback of Orthogonal Frequency Division Multiplexing (OFDM) systems is the high peak-to-average power ratio (PAPR), which leads to a significant reduction in power efficiency. In this research discusses different PAPR Reduction techniques in OFDM. Techniques like clipping, Selective Mapping (SLM), Partial Transmit Sequence (PTS) based different modulation and different channel. Clipping technique is simple, SLM reduction technique; generation of phase sequence is very random...
It is very important to protect country's borders from intruders who carry out illegal activities such as terror attacks or smuggling of people or their properties. Borders should be monitored to avoid the above-mentioned risks by using border surveillance system which consists of ground surveillance radar and camera to achieve this mission. To perform the monitoring, signals are sent from radar to the microcontroller, according to target location, in order to move the camera to capture...
IPv6 is the next generation in internet protocol. It is developed by the Internet Engineering Task Force (IETF) to provide better performance and also to provide new services in comparison to IPv4. It is intended to serve for sufficient IP address space to meet the present Internet growth. Security attacks have been common across the Internet, therefore in order to protect IPv6 networks from security attacks; IPSec has made an inbuilt component of IPv6 to ensure the integrity, authentic...
ABSTRACT Electricity is one of the foremost necessary resources during this century which needs to be conserved otherwise the next generations might be deprived of the opportunity. However there is tendency we leave our various rooms and offices and forget to switch off the lights and fan, so electricity is wasted. Additionally in most cases, switches of lights and fan are situated in places where we might need to search for them in the dark and just in case of guests, it becomes tougher. Th...
ABSTRACT This study investigated the influence of mud channel characteristics on real-time data logging while drilling. Drill string bore filled with flowing mud as the data transmission medium in mud pulse telemetry can have significant changes in its properties as a result of mud type (waterbased mud or oil-based mud) which selection depends on the formation being drilled and depth penetrated. Logging data are transmitted to the surface modulated onto pressure pulses which amplitudes are g...
Abstract Reliable electricity supply is essential for development. As a result, demand for electricity has continued to increase globally, occasioned by the fact that electricity is highly portable and can be transformed from one form to another to meet needs. In Nigeria and most developing countries, electricity supply from the public utility is not only insufficient but highly erratic. The effect of this is adverse on critical and sensitive infrastructure that depend on uninterrupted power...
ABSTRACT Businesses (Manufacturing, Merchandising or Service Delivery) have similar organizational structures like Administration, Human Resources, Marketing, Accounting and Customer Care/Public Relations. Stand alone software products have been developed to enhance operations in each of these business. The business management system software developed in this project is aimed at integrating these software products into a single system that will provide solution to different management...

ABSTRACT In Multiple Input Multiple Output (MIMO) Radar every antenna element transmits different waveforms, these waveform diversity enhanced MIMO Radar system dramatically. Coherent MIMO radar array elements are close enough so that every element sees the same target radar cross section (RCS). The target response is mainly interrupted by the unwanted signals (Noise, Clutter, and Jamming) associated with receiving signal that degrades Probability of detection as well as performance of MIMO r...
Abstract The development of technology has a good impact on all sciences including medicine. The use of modern technology in medicine reduces the incidence of serious medical errors; some diseases need to follow their symptoms for a long time to be discovered. There is a problem in tracking symptoms for patients at each time visiting the hospital where data cannot be saved and retrieved when needed. By using the cloud computing technology, all hospitals can be linked by the Software-as-a-Ser...
ABSTRACT An easy-to-use and accurate multi-frequency path loss model is a necessary tool for heterogeneous radio network planning and optimization towards achieving a smart campus. The learning ability in artificial intelligence may be exploited to reduce computational complexity and to improve prediction accuracy. In this research project, an optimal heterogeneous model was developed for path loss predictions in a typical university campus propagation environment using machine learning appr...
