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...
ABSTRACT This paper deals with the measurement of dielectric properties of some local cereals (com, beans, rice) in the audio frequency range (0.3- 20KHz) since dielectric properties of various agrofoods and biological materials are finding increasing applications, as fast and new technologies adapt/adopt these cereals for use in their respective industries and research laboratories. A Marconi instrument, 0.1% universal impedance bridge together with a specially designed and constructed coax...
ABSTRACT Biometrics is a physical, electronic and biological means of providing dependable and accurate identification of people. It entails data acquisition, storage and subsequent matching at points of access or identification. Biometrics is an emerging technology that identifies people by their physical and/or behavioral characteristics and practically requires the person to be identified to be physically present at the point of identification. In this thesis, efforts to improve biometric...
ABSTRACT Cloud computing has not only emerged as an accepted computing paradigm, but is fast penetrating into major sectors of human endeavor. These include banking, human resources management, justice administration, investigation, academia/research, commerce, health administration etc. Based on the public and experts concerns about cloud applications in the mentioned sectors, preliminary investigations were carried out and it was found that security, and in particular, authenticating...
ABSTRACT Energy systems based on fossil oil products have witnessed increased demand all over the world with prices reaching new peaks, and continue to further weaken African economies. Potential biofuel oil sources, production and their optimization in standard to fossil equivalent should be sought. Sour plum (Ximenia americana L.) seed oil as one potential biofuel was extracted from plant seeds using screw press then tests were carried out to evaluate its properties as substitute for kerose...
The purpose of this project was to build a motion detector. The main components used were the Arduino microcontroller and the PIR sensor. The project also used an LED and a Piezo buzzer to indicate when motion was detected. The group sought to demonstrate the workings of each component as well as how they work together to carry out the task. The group also drew up a circuit from which the components were connected. The main objective for the project was to practice the skills learnt over t...
ABSTRACT This research work undertakes the development of water pumping system (with emphasis on Irrigation) that is capable of automatically managing water budgets from a reservoir through a microcontroller subsystem. The water pumping for irrigation system can be used in gardens, farms, urban/rural water supply systems, and in fact, general water management systems for both domestic and industrial applications. The key objective of this research is to develop a user-friendly and efficient ...
Light fidelity (Li-Fi) is new technology using lights (LEDs) as transceiver to send and receive data. However, when Light fidelity access points (attocells) placing near to each other in the network, they interfere each other with phenomena called co-channel interference which decreasing quality of the signal. In this thesis, fractional frequency reuse introduced as solution to solve this problem. MATLAB simulator showing the impact of fractional frequency reuse to solve problem.
ABSTRACT This research work on “Modelling and Simulation of Leakage-Induced Pressure drops along oil and gas pipelines tends to develop flow equations that can detect and localize leakages in oil and gas pipelines by modifying the Darcy-weisbach equation for liquid/oil flow, and the Panhandle B equation for natural gas flow in pipelines. These modified equations were simulated using matlab to show how flow rate values for the oil and gas pipelines vary when; the pipeline is working at full...
Abstract A Mobile Ad-hoc Data Network (MADNET) is a self-configuring, infrastructure-less network of mobile devices (nodes) where nodes communicate with each other using multi-hop wireless links. Node failures and arbitrary movement of nodes at higher node velocity break the routes and lead to the frequent operation of rebuilding routes that consume lots of the network resources and the energy of nodes. This study, analyses the impact of node velocity on performance of two MADNET Transport p...
ABSTRACT Data storage and retrieval are at the centre of today’s applications. Currently, no organization can effectively carry on its activities without one form of database or the other. Indeed, one of the key challenges of information technology organizations is how to ensure quality and reliable database administration. Consequently, if the database and the server that support the applications are unavailable it could lead to considerable costs in terms of efficiency, loss of revenue a...
ABSTRACT Cardiotocogram based monitoring needs a reliable fuzzy logic system to reduce the incidence of unnecessary medical intervention and fetal injury during child labour, due to a high degree of uncertainty and imprecision. Presently, electronic fetal monitoring is based almost entirely on the Cardiotocogram (CTG), which is a continuous display of the fetal heart rate (FHR) pattern together with the contraction of the womb. Despite the widespread use of the Cardiotocogram, it has li...
A temperature sensor is a device that reads the temperature of the surrounding and relays the temperature either in degrees Celsius or Kelvin. The LM335 temperature sensor (used in the experiment) gives out the temperature in degrees Celsius. It is calibrated to output the millivolt voltage reading in proportion to its units of measurement i.e. it outputs 10mV/0K. The main objective of the project was to build a temperature sensor circuit using a LM335. As part of the project, it was als...
