 Abstract

Oil exploration has enormous economic benefits; however, these benefits are associated with environmental issues arising from oil spills. Numerous methods exist for cleaning up oil spills along with their aftereffect as well as huge financial burden. Hence, the shift to methods that are environmentally friendly and cost effective is imperative so the efficiency and mechanics of using human hair to clean up crude oil contaminated water using various parameters such as contact time, recovery and reuse, adsorbent dosage, temperature, modification. Human hair, being hydrophobic and a biosorbent, has proven to be an efficient material in removing oil from water with a maximum adsorption capacity of crude oil as well as its recovery and reusability. It is independent of the external factors like temperature etc. unlike other methods. Human hair can be modified into boom to clean-up oil spills. Since hair is just a waste product, it has proven to be a cost-effective method. It can adsorb up to 9 times its own weight. Lately, it has been used to clear up a few oil spills successfully and has proven to be a quick process. This is a promising area that researchers need to focus more on in order to explore the huge benefits it presents

 Abstract

Indian cities are witnessing huge influx of migrating population from smaller towns and cities leading to population increase resulting in increase in property demand and land scarcity. As a result, High-rise residential project demand has been increasing in the Metropolitan Cities. The importance of construction industry in India has grown significantly but at the same time, construction projects in India have become infamous for delays and cost overruns. Construction delays are considered one of the most recurring problems in construction industry and has adverse effects on Project�s success in terms of cost, time and quality. There are many research works conducted to identify various causes of delay in construction and their mitigation measure, yet the problem of delay continues to prevail. Indian metro cities like Delhi and Mumbai include higher number of Residential High-rise projects that have been witnessing delay of over 5 years. While most of the projects are executed conventionally with an emphasis on solving the problems as and when encountered, which eventually leads to delay, most of the delays can be prevented, provided due consideration are adopted in pre-construction stage to mitigate the risk of delays encountered during execution stage. The research aims at identifying the reasons of delay in pre-construction stage that are the root cause of various delays encountered during execution phase of Residential High-rise project. The research also intends to identify mitigation measures for the root causes of delay identified to prevent delays in construction project before the execution begin to prevent the risk of schedule overrun.

 Abstract

With this system what we are trying to propose is a real time face recognition attendance system, it would not only be capable of identifying the faces in an image but will also try to identify a person in the image. the overall objective is to identify the faces in a live stream of a video, i.e. the stream might come from a video recording (CCTV) or it can also identify the faces from a WEBRTC video stream. Today due to covid19 epidemic most of the interactions are being conducted online or via internet. This would also be a contact less authentication system if integrated with the suitable hardware WEBRTC today is being widely used in Real time communication because of the simplicity and performance. This system would provide interesting dashboard of the analysis done using ELK Stack which would be embedded in this application.

Abstract Nowadays overweight and underweight are two major problems in national and international scenario. The degree to which a person is overweight or underweight is generally described by his/her Body Mass Index (BMI). The researcher was intended herself to find out whether BMI influences academic achievement of the secondary school students. If there exist any relation between BMI and academic achievement, then students will remain conscious about their performance. Guardian and teachers can also make themselves aware about students� body weight. BMI and academic achievement were considered as the variables of the study. The researcher selected 226 students of class IX and X from the district of North 24 Parganas of West Bengal as sample of the study. To measure academic achievement the researcher has considered the marks obtained by the student in their last examination passed. BMI was calculated from height and weight ratio of the students by Stadiometer and Weighing machine respectively. On the basis of statistical analysis and interpretation it was found that academic achievement is not influenced by BMI of the learners. Yet there was no correlation between BMI and academic achievement, students are recommended to maintain their BMI within normal value to prevent various health problems.

 Abstract

India, on attaining independence; subsequent steps were taken up to strengthen the economy of the country. It is unquestionable fact that economy forms the backbone for sustenance of any country. It is highly impossible for a country to do anything without a robust economy and economy is nothing but optimum management of resources of a country. The foundation for independent India�s economy was set in a planned sector which brought in its framework planned utilization and consumption of resources.. It was only at this time when the Monopoly and Restrictive Trade Practices Act; hereby referred as MRTP was passed with the following two objectives: a] to prevent the concentration of economic power in few hands that would thereby lead to monopolistic behavior and b] to curb the unfair and restrictive trade practices. The ulterior motive of the same was to protect the interests of the consumers. The present paper analyses the paradigm shift of the Competition Act from that of the MRTP. Further, the paper cites environment of effective implementation of the provisions of the Competition Act by the Competition Commission of India particularly with reference to cartels.. The paper concludes by analyzing the role of CCI by penalizing cement cartel for anti-competitive activities thereby establishing the effective ways the Competition Act has protected the interest of the consumers

 Abstract

Color Space Conversion is an integral part of various computer vision applications such as face detection, object detection and surveillance systems. To achieve ease in processing, feature extraction, compression and storage of image and video data color space conversion technique is required. If computation is performed on gray images, which has 8 bit wide pixel, rather than color images, which has 24 bit wide pixel the resources required for real time implementation of all these applications will be reduced. Reversible logic has received a great deal of attention from many researchers over recent years for its enormous potential for application in quantum computing and nanotechnology due to its ability to reduce power consumption, which is the main requirement in low power VLSI design. A color space conversion scheme using reversible logic gates is presented here. Color-to-gray scale conversion using reversible logic aims at embedding the chromatic information of a full color image into its gray scale version such that the original color image can be reconstructed in the future when necessary. Color Channel averaging method is implemented in this paper. By converting RGB to Gray scale using reversible logic it helps to increase the operation speed and reduce the storage space. Implementation of color space converter using reversible logic nullifies the internal energy dissipation as it provides a computation that does not result in information loss. The implementation of reversible logic circuits for converting RGB to Gray scale was done and the functionality verification was done on Spartan xc3s400 FPGA platform. The results are evaluated in terms of hardware utilization and power for FPGA.

 Abstract

Tomatoes were pre-treated with Syzygium aromaticum, dried and evaluated for its antioxidants, physicochemicals and antimicrobial properties. S. aromaticum treatment were made at varying concentrations of 2.5, 5, 7.5 and 10%. Sun drying and oven drying (60oC) were used to effect the drying process. Dried tomatoes samples treated with no S. aromaticum served as control samples. Selected properties evaluated includes; moisture content, ash, pH, crude fibre, titratable acidity, ascorbic acid, total carotenoid, lycopene and total viable and fungal count using standard methods. The results obtained showed that treatment with S. Aromaticum significantly (P<0.05) increased the pH and crude fibre when compared with the control samples. Ascorbic acid value of the oven-dried control sample was significantly reduced compared to the ascorbic acid value of the sun-dried control sample. However, in treatment with varying concentrations of S. aromaticum, the ascorbic acid values of oven-dried samples were better retained. The lycopene and total carotenoid value were also reduced in oven-dried samples compared to sun-dried samples when treated with varying concentration of S. aromaticum. There was considerable reduction in total viable and fungal count of tomatoes treated with S. aromaticum compared with the control samples. The findings revealed that S. aromaticum was a good pre-treatment for preserving quality of dried tomato.

Control systems are an integral part of modern society, and a major part. They consist of subsystems and processes which are assembled in modern industry for the purposes of controlling many processes. Motion control is required for domestic or industrial works. Systems used for such controls are called drives. By measuring output response and feeding it through feedback system and comparing them at summing junctions, the closed loop systems overcome the disturbance problem. An analysis is made of the performance of a dc motor controlled by a proportional-integral derivative (PID) controller. Overshoot appears with large settling time thus confirming a PID control behavior. In this paper Ziegler Nichols (ZN) tuning algorithm is the tuning method used for the proposed dc servo motor position control model. A computer based model is furnished here (using MATLAB SIMULINK).

 Abstract

Crisis is the truth of today�s fast paced business world. Rapid change in organization, changing economic conditions, problems of employees, unexpected technological changes and political effects cause instability on business world. This instability appears out of state control as economic disruptions which result in crisis. Crisis that affect our country as well as all other countries in the world also influences not only vacated people but also other individuals who concerns about losing their jobs. This economic uncertainty seemingly interests corporations. An environment is also one of the factors that affects crisis. If crisis are not brought under control or managed properly, they will come about and create chain crisis. Because of the increasing chaos, change from authoritarian leadership through teamwork and participative management mentality has been observed. Commerce is getting more and more complicated and complex. These changes have transformed traditional crisis leaders to a leader model which makes scenario analysis and work done in co-ordination with a team by gathering lots of different point of view to create optimum solution. Leadership and crisis concepts are discussed together in order that implementation of leadership in crisis can be easy to understand. Also, Crisis leadership is regarded as optimally and timely assessment process of adverse condition�s effects whatever its reason is.
