Seismic retrofitting of existing reinforced concrete building
It is commonly observed that many RC Building collapses during an earthquake are those building which is non –engineered or those RC Buildings which are not constructed as per codal provisions. Some of such buildings have deficiencies in whole structure or individual structural members which don’t have the adequate lateral capacity to counter the seismic demand. Before retrofitting of structure it is required to perform necessary assessments and evaluations of structural member or location deficiencies are found. In this case study, a G+3 storey RC Building is considered for seismic analysis which is located in the zone –IV to calculate the additional seismic strength of structural members like beams and columns. Based on this analysis retrofitting measures are suggested. This analysis is performed by using Stad pro-V8i software. The recommendations are based on IS – 15988, IS – 1893, IS – 13920 and FEMA codes provisions. The method adopted for seismic retrofitting of structures is RC Jacketing.

Road quality analyser
The condition index (cracking index) is one regular metric used by many countries to measure their road quality and justify the budget spent every year on the road repair. These decisions are dependent on the evaluation criteria that are subjective but not representative. In this paper, we confer about our initial approaches to solve the problem of data asymmetry in decision-making about the road quality. The proposed work explains the process of determining road-defects using data collected by the Road Quality Analyser (RQA). A web-based interactive user interface to host a large amount of data collected by the device RQA towards digitizing the process of road quality inspection. This approach of combining data and device for the assessment of road, which enables the government to make accurate decisions on road repairs and it will lead to an anticipative response which will result in significant cost saving.

A review on geology, geomorphology, origin and textural analysis of red sediments of east coast Visakhapatnam
Red sediments are of a unique feature that exists in the east coast near Visakhapatnam. The Origin has been debated for over the years, most accepted is formed by the denudational remnants of a great sandbank of Pliocene times or isolated banks formed around sunken hills. Red sediments are formed by the cumulative work of wind and running water, where the red colour pigment is being preserved by the digenetic breakdown of iron-bearing minerals. Iron oxides derived from the red soils in the sources area (Khondalite terrain). Favorable environmental conditions for the preservation of the pigment in the depositional basin. The colour of the red sediments is mostly moderate reddish brown and moderate red. Moderate yellowish brown and dark reddish brown sediments are occurring in certain parts of Visakhapatnam region. The upland soils are pale reddish brown to moderate reddish brown. Many geomorphic features are observed like gullies, buried channels, Lineaments, beach ridges, sand dunes, wave-cut terrace, knick points and waterfalls, yellow sand unit, reddish-brown concretion bearing sand unit, brick-red sand unit, light yellow sand unit, duricrust, and pebble beds. Textural analysis has been made in these areas; results show that these are originated from under fluvial environment.

Enhancement SNR for OFDM systems by using PSO algorithm
This dissertation deals with the channel estimation techniques for orthogonal frequency division multiplexing (OFDM) PSO systems such as in IEEE 802.11. Although there has been a great amount of research in this area, characterization of typical wireless indoor environments and design of channel estimation schemes that are both robust and practical for such channel conditions have not been thoroughly investigated. It is well known that the minimum mean-square-error (MMSE) estimator provides the best mean-square-error (MSE) performance given a priori knowledge of channel statistics and operating signal-to-noise ratio (SNR). However, the channel statistics are usually unknown and the MMSE estimator has too much computational complexity to be realized in practical systems. In this work, we propose two simple channel estimation techniques: one that is based on modifying the channel correlation matrix from the MMSE estimator and the other one with averaging window based on the LS estimates. We also study the characteristics of several realistic indoor channel models that are of potential use for wireless local area networks (LANs). The first method, namely MMSE-exponential-Rhh, does not depend heavily on the channel statistics and yet offer performance improvement compared to that of the LS estimator. The simulation results also show that the second method, namely averaging window (AW) estimator, provides the best performance at moderate SNR range.

A critical survey on the involvement of ICT in the teacher’s training institutes of West Bengal
Teachers occupy a prominent place in any society and in any educational system. This is particularly true in the case of India. From ancient time teachers have been enjoying special status and position in the Indian society as well as in the field of education. In almost all societies and cultures teachers have been regarded as a person who possesses certain attributes, competencies, and traits to succeed both in the classroom and in society as a whole. Quality of teachers is the measure of the strength of an educational system and quality of teacher depends on the quality of the teacher education. Therefore a sound programme of teacher education is necessary for the improvement of the education system in the country. With the world moving rapidly into digital media and information, the role of ICT in education is becoming more and more important and this importance will continue to grow and develop in the 21st century. In this respect, teacher education institutes play a vital role in providing quality education to the teacher trainees using ICT. But it is very regrettable to say that in this Modern Era all training colleges of West Bengal are not been able to accept ICT in its full form. This research paper will focus on the critical survey on the involvement of ICT in teachers’ training institutes of West Bengal. This is a Descriptive study where Survey method will be used. To conduct this research the researcher will use the questionnaire as a research tool. The population of this research work is the total teachers training institutes under WBUTTEPA but to have a control over the data and to time factor the researcher delimitated it and had taken only 6 colleges. By using Stratified random sampling the researcher had taken the sample from 6 training institutes of West Bengal and from each college 10 teachers had been taken. A total number of sample 60. To analyze the qualitative data in a quantitative way the researcher will use Statistical Analysis using t-test. Education is a very socially oriented activity and quality education has traditionally been associated with strong teachers having high degrees of personal contact with learners. The use of ICT in education lends itself to more student-centered learning settings and therefore ICT can improve teaching by enhancing an already practiced knowledge and introducing a new way of teaching and learning.

Composite brake friction lining for rotor and drums
The rubbing brake functions as a basic assurance for general work and wellbeing operation of vehicles and mechanical supplies. Erosion and wear practices of brake's grinding materials are considered as a vital subject. In this article, grating materials were arranged by framework classes, and their significant segments were presented first. At that point, the favorable circumstances and impediments of every grinding material were compressed and examined. Besides, the small-scale reaching practices on erosion interface and the arrangement system of different contact movies were talked about. At last, the persuasive standards and practices of erosion materials were outlined. It is inferred that the grating film, a middle of the road item in braking, is significantly useful to shield erosion materials from being genuinely rubbed. The braking conditions have muddled impacts on rubbing and wear practices of brake. By and large, the grinding coefficient has a tendency to be genuinely low while the wear rate increment Quickly under a condition with high temperature, braking weight, or beginning braking speed
