The seminal is based on designing and implementing of attendance capturing system using live feed electronic systems. This process of face recognition involves the inspection and study of facial features in an image, and the recognizing those features with comparing them to one of the many faces in the database. Some of the algorithms capable of performing face recognition are the Discrete Cosine Transform, Gabor Wavelets method, the Principal Component Analysis (PCA), 3D recognition methods, etc. Some real issue to be consider in this live feed face recognition method are: Speed Process and Availability. Accuracy, Time limitations, putting all these in action the PCA based method of face recognition provides real quality and better result because: it is a more Efficient, Simpler and easer method to implement it and it has a Very fast computation down time. The PCA has the ability to recognizing a face with a different background and environment.

This research focused on the comparative performance analysis of Quadrature Amplitude Modulation (QAM) and Quadrature Phase Shift Keying (QPSK) modulation techniques employed in W-CDMA system. Site investigation was conducted and the Received Signal Strength (RSS) measurement taken. From the RSS measurement, the path loss was evaluated and was used to estimate two Quality of Service (QoS) parameters - Signal-to-Noise Ratio (SNR) and the Bit Error Rate (BER) of the modulation techniques under study. These parameters were used to characterize the modulation techniques upon which a comparative analysis was obtained to achieve maximum data throughput consideration. The result of the analysis revealed that as SNR decreases, errors increase. The average estimated SNR of QPSK was slightly greater showing 15.89dB (50.4%) against 15.64dB (49.6%) for QAM, giving rise to why the bit error rate of QAM technique was higher than QPSK. In all, the research revealed that QAM offered higher coding rate which helps to sustain better data capacity and throughput. QPSK on the other hand gave an improved BER performance. From these developments, network designers usually make a tradeoff between spectral efficiency which QAM offers and improved BER performance by QPSK. Modulation scheme implemented therefore in any form of wireless network affects the BER performance which in turn affects the data rate as well as the throughput of the communicating devices.

The cracks are produced on rode due to heavy load by using steel wool fiber cracks will be healed. Microwave technology is considered as an alternative technique to promote self-healing of asphalt mixtures with cracks will be heated filled metallic fibers. It is well known that steel wool fibers can also be used in order to modify the mechanical, electrical and thermal properties of asphalt mixtures.The use of Self-Healing Asphalt in practice is possible. It can be a solution for areas with dense traffic and with a strong need for noise reduction. Even the first experiments of a healing action have taken place.The development of such areas of self-healing technology for asphalt pavements will truly revolutionize asphalt pavement design. This will also lead to another evolutionary step in road construction and design and bring the idea of self-healing roads from science fiction to reality. Adding steel fibers to asphalt ensures that once it is worn out and cracks/potholes appear, it only needs repair. Iron molecules are heated remotely by introducing a fast-changing magnetic field. Once heated by induction, the steel fibers immediately release heat to the mortar, which melts briefly. This causes the asphalt to reset to its original structure. An induction machine is used in the repair in a process called guiding. There is little loss of energy since it travels directly between the steel fibers and mortar – where the cracks form. Additionally, the entire surface needs not be heated, only the part where cracks form. In two to three induction regimes, the lifespan of the asphalt is prolonged up to 20 years from the present 10 to 12 years.

The purpose of the study was to analyze the effect of job satisfaction and organizational support on Teaching Effectiveness. The entire study was conducted among 400 faculties of Private Engineering & Management Colleges of Uttar Pradesh. This paper explores the interaction effect of organizational support and job satisfaction. The study is based on primary data in which multistage technique was used to select the sample and questionnaire is the research tool. The paper defines the statistically insignificant interaction effect of organizational support.

This paper presents the influence on undergraduate and post graduate students studying in the various higher learning institutes due to lockdown imposed in the wake of COVID-19 Pandemic. An online survey was conducted from 1st July to 30th October 2020 to assess the influence on undergraduate and post graduate students studying in the various Government, Government aided and un-aided first grade colleges affiliated to Karnatak University, Dharwad, Karnataka, INDIA due to lockdown imposed in order to curb the COVID-19 Pandemic. A structured questionnaire was framed and the response was consolidated through Google forms sent via various social media platforms such as WhatsApp, TelegramApp and E-mail to compose the student’s opinion. Around 1200 students are turned up their interest and actively participated in the exhaustive survey and submitted their responses. Simple percentage distribution was used to appraise the learning condition of the students. In the midst of lockdown period, major chunk of respondents were deliberately hang on to the virtual classes and webinars. Students have been experiencing various grievances related to power breakdown, network issues and difficulty in affording of sophisticated gadgets. Majority of the students not satisfied with virtual classrooms and have not shown much interest for the semester end examination to be conducted online.

The study is an assessment of quality of life in peri-urban settlements of Uyo Capital City in Akwa Ibom State, Nigeria. This is sequel to the perceived low level of living that is experienced in the peripheral settlements of Uyo Capital City. Settlements identified within the limit of the study area were 36 in number. Data on 15 dependent variables thus contributing to socio-economic infrastructure and activities to the quality of life of the people were collected from the field and weighted. Using systematic random sampling, 10% of households were sample in each of the settlements. Seven independent variables of socio-economic nature were identified and measured. Spearman’s Correlation statistics was applied to investigate the influence of socio-economic indicators on quality of life. The result of the analysis indicated that the population and education variables were significant in explaining the levels of quality of life in the study area. The Population variable accounted for 88.9% of the total variance in quality of life (r = 0.943). This was closely followed by education variable which accounted positively (r = 0.496) but very weak contributing 24.6% of the total variance in quality of life in the study area. The overall assessment hammered on inadequate socio-economic infrastructure in the study area and hence it is recommended that adequate intervention be made in infrastructural provision and effective planed distribution strategy for enhanced quality of life.

Soil is one of the most important and primary media for any construction work. The strength and durability of any structure depends on the strength properties of soil. Nowadays, scarcity of good land for construction which is one of important problems for engineers using land increases demand for unsuitable soils. When the mechanical qualities of unsuitable soils are lower than those required, reinforcing can be an option to improve performance, notably in enhancing its strength. Use of waste material is alternative method as low-cost material for soil reinforcing applications. In this study, two waste material were used together at different content. The waste material mixtures obtained from marble dust and scrap tire rubber were used for the stabilization of clayey soil. Unstabilized and stabilized clayey soil samples subjected unconfined compressive strength tests to investigate the waste material mixtures on the strength properties of clayey soils. As a result, it is concluded that the waste material mixtures obtained from marble dust and scrap tire rubber can be successfully used for the reinforce of clayey soils in the geotechnical applications.
