This research developed a teledensity growth model in Nigeria using a multiple regression approach in order to understand the Nigerian telecommunication growth trend for predictive analytics. Data were obtained from four GSM network operators, fixed line operators and CDMA providers. The data used captured number of subscribers and a monthly data summary from February 2012 to January 2013. Using multiple regression technique, an estimating for teledensity growth model was achieved with MATLAB R2011a. The model was tested and validated for prediction and forecasting at a significance level, α = 0.05. Advanced Statistical tools like STATASE, Minitab, E-view and Time series analysis were used in this study. Using the Augmented Dickey-Fuller (ADF) test, it was observed that the teledensity time series trend were found to be stationary overtime and had no unit root at second difference. The findings of this study showed that teledensity growth has an increasing trend over time which implies that the linear trend model obtained from the time series regression analysis can be used to make predictions for future behaviour of the process. Hence, six years prediction on the teledensity growth pattern was made and it was found that in the year 2018, that teledensity growth will increase to about 148.4%. Given a population and subscriber base, the model could be applied in any country of the world.

The security becomes an important issue of communication and storage of image due to the growth of multimedia application. Encryption is one of the ways to ensure high security. Images are used in many fields such as military and medical science. They are stored or transferred through network, security of such image data is important. Encryption involves applying special mathematical algorithms and keys to transform digital data into cipher code before they are transmitted and decryption involves the application of mathematical algorithms and keys to get back the original data from cipher code. Information privacy becomes a challenging issue. In order to protect valuable data or image from undesirable readers, image encryption and decryption is essential. In this approach, encryption phase by using selective encryption technique original image pixel values are completely concealed so that an attacker cannot obtain any statistical information from an original image. An encoder quantizes the sub images and Hadamard transform is applied to reduce the data amount. At the receiver side with the cryptographic key, the principal content with higher resolution can be reconstructed when more bit streams are received. The quality of the reconstructed image is measured by calculating peak signal to noise ratio (PSNR).

Friction stir welding (FSW) uses a non-consumable tool to produce frictional heat in the adjoining surfaces. The welding parameters like rotational speed, welding speed, tool pin length, and tool shoulder diameter play a major role in deciding the joint properties. In this work, an attempt has been made to analyse the effect of various tool profiles have been used to fabricate joints by using constant thickness (3mm) work piece of aluminium alloy. The mechanical properties of welded materials are measured in terms of tensile strength. With the help of vertical milling machine create the specimen by friction stir welding (FSW). Now using universal testing machine on which tensile testing of the welded specimen was carried out. After that by using design of experiment (DOE)concept. Experimentally were carried out to predict tensile strength of the welded joint. After comparison of predicted and practical values of tensile strength conclude that with increase in pin length tensile strength increase contently and tool geometry with a large shoulder diameter together with high welding speed leads to decrease in welds speed leads to decrees’ in tensile strength of the welds work pieces.

A sensor is a miniature component which gauges physical parameters from the environment. A sensor measures the physical parameters and transmits them either by wired or wireless means. In wireless medium the sensor and its allied components are called as node. A wireless sensor node is self-assured by a processor, local memory, sensors, radio, battery and a base station accountable for receiving and processing data collected by the nodes. The incorporation of multiple types of sensors such as seismic, acoustic, optical, etc., in a single network platform and the evaluation of the overall coverage of the system also presents numerous interesting challenges. The sensor-based military applications involves intrusion detection, perimeter monitoring, information gathering and smart logistics support in an unknown deployed area, sensor-based personal health monitoring, location detection with sensor network and movement detection using wireless sensor network. This paper gives a detailed description about the impact of clustering mechanism in dense wireless sensor network

A Vehicular Ad-Hoc Network (VANET) is a special form of Mobile ad-hoc network used for the communication between nearby vehicles and between vehicles and fixed roadside equipment. VANETs are an important component of Intelligent Transport System (ITS) that combines computer and communication technologies for traffic management to reduce traffic congestion, improve traffic efficiency, avoid accidents and improve road safety. Vehicular safety is an important application of VANET and these include vehicle collision warning, brake warning from a preceding car, obstacle warning and other emergency notifications. In this paper, we focus on accident prevention and propose a Safety Distance Calculation methodology that is based on the relative velocity and distance between the vehicles. The driver is warned, when the safety distance to another vehicle is reached so that the driver can take appropriate steps for collision avoidance. The proposed system is based on the positional information provided by GPS receivers. As most cars, today, are equipped with GPS receivers, our proposed system provides a simple and feasible solution for accident prevention. Since, the relative distance between the vehicles is used for computation; the safety distance can be accurately estimated

Then, using the DCT coefficient, face image can be recognized using MFSVM classifier. The experiment is carried out on the ORL database the result is encouraging, which achieves high accuracy

In this paper, Data Envelopment Analysis (DEA) was applied using Variable Return to Scale (VRS) model to determine bandwidth consumption of two algorithms during video conferencing over wireless network. Recent researches conducted focused on Constant Return to Scale (CRS) model where all Decision Making Units (DMUs) are operating at an optimal scale. DEA employing VRS was used on simulation results of Improved Network Coding Algorithms (INCAs) of two and three parameters to determine the better coding algorithm. The two Simulation results showed that, the INCA with three parameters is more efficient than the INCA with two parameters. This is ascertained from the mean efficiency of INCA with three parameters which are; 0.941, 0.934 and 0.812 for 20, 50 and 60 nodes generated at random when compared with mean efficiency of 0.847, 0.909 and 0.801 for INCA with two parameters using the same number of nodes generated at random.
