MASSIVE MIMO OPTIMIZATION USING SELF-OPTIMIZING NETWORKS

Massive multiple-input and multiple-output (MIMO), which refers to the practice of employing a large number of antennas at a base station to achieve better spectral efficiency using the same time and frequency resources, has received extensive interest as a potential solution for a next-generation cellular system. Presented herein are techniques to optimize a MIMO antenna configuration in order to reduce power consumption (and therefore operation cost) in a next-generation cellular network, paving the way to an energy-efficient wireless network

ANTIOXIDANT AND ANTIPROLIFERATIVE POTENTIALS OF MARINE ACTINOMYCETES

Objective: The aim of present studyis to isolate and characterize a novel actinomycetes strain from marine sediments collected at Kakinada coast. To evaluate antioxidant and antiproliferative activities of the crude methanolic extract of isolated actinomycetes.Methods: Actinomycetes was isolated from marine sediments collected at Kakinada coast using starch casein agar. Morphological, biochemical and molecular characterization was performed and the crude methanolic extract was used for determination of in vitro antioxidant activity and antiproliferative activity against MDA-MB 231 breast cancer cells.Results: The crude methanolic extract exhibited significant antioxidant activity with IC­50­ value in the range of 30-46 µg/ml in different radical scavenging assays. Moreover, the extract showed concentration dependent cytotoxicity against triple negative breast cancer cell line, MDA-MB 231 with IC50 of 42.5µg/ml. The extract also inhibited cell proliferation with IC50 value 44.1 µg/ml probably by arresting cell cycle at S phase. The antioxidant activity of the extract was strongly correlated with cytotoxic and antiproliferative activity.Conclusion: The isolated marine actinomycetes can be the potential source of antioxidants with the anticancer property

Modern Privacy Threats and Privacy Preservation Techniques in Data Analytics

Today we are living in a digital rich and technology driven world where extremely large amounts of data get generated every hour in the public domain, which also includes personal data. Applications like social media, e-commerce, smartphone apps, etc. collect a lot of personal data which can harm individual privacy if leaked, and hence ethical code of conduct is required to ensure data privacy. Some of the privacy threats include Digital profiling, cyberstalking, recommendation systems, etc. leading to the disclosure of sensitive data and sharing of data without the consent of the data owner. Data Privacy has gained significant importance in the recent times and it is evident from the privacy legislation passed in more than 100 countries. Firms dealing with data-sensitive applications need to abide by the privacy legislation of respective territorial regions. To overcome these privacy challenges by incorporating privacy regulations, we have designed guidelines for application development, incorporating key features of privacy regulations along with the implementation strategies which will help in developing data-sensitive applications which can offer strong and coherent privacy protection of personal data

Physico-chemical and microbial analysis of water samples in Anakapalli Municipal Corporation

An investigation of microbiological and physico-chemical properties of drinking water samples from five different locations in Anakapalli municipal corporation. The water samples are subject to physico-chemical analysis by standard methods. The microbial isolation was done by a streak plate method on nutrient agar and on selective media for their identification. The final identification was done according to the Bergey’s Manual. The physico-chemical characters of all the five drinking water samples were within the recommended permissible level of WHO. The total plate count was above the WHO guideline values (<10CFU’s/ml) in the five water samples. The highest count was noticed in S5 sample (54 CFU’s/ml). The highest coliform count was observed in S3 samples (11/100 ml). Six isolates of bacteria namely: E.coli, Enterobacter aerogenes, Klebsiella pneumonia, Salmonella, Shigella, and Staphylococcus were isolated, which are highly pathogenic, the result of the study indicates that the water in Andhra University pump houses is highly contaminated and not safe for drinking and utility purposes. The study therefore, stresses on the need to control the fecal pollution of water bodies

Analysis the effect of condenser pressure (vacuum) on efficiency and heat rate of steam turbine

Electricity plays a vital role in our daily life. The power demand is increasing day by day due to increasing the population. The power is required for Industrialization and development of nation. Our country mainly depends on thermal power plant for electrical supply. In thermal power plants turbine is considered to be HEART of the plant. Maintained required condenser parameters to improve the performance of turbine and these parameters direct impact the economical growth of power plant This project involves the construction features, start up, and Shut down, emergency operation and safety protections of the 32 mw steam turbine. The main aim of this project is analysis the how to effect the condenser pressure (vacuum) on efficiency and heat rate of regenerative steam turbine by mathematical calculations

The Indian oilsardine Sardinella longiceps, locally called as ‘burra kovallu’ or ‘Kerala kovallu’ forms a juvenile fishery during October - November along the Visakhapatnam coast. This seasonal juvenile fishery is the major source of income generation for the fishermen of Jalaripeta, Visakhapatnam

Tensile testing of cellulose based natural fibers for structural composite applications

A series of tensile tests were conducted on a Lloyd LRX tensile testing machine for numerous natural fibers deemed potential candidates for development in composite applications. The tensile tests were conducted on the fibers jute, kenaf, flax, abaca, sisal, hemp, and coir for samples exposed to moisture conditions of (1) room temperature and humidity, (2) 65% moisture content, (3) 90% moisture content, and (4) soaked fiber. These seven fibers were then tested for the four conditions and the mechanical properties of tensile strength, tensile strain to failure, and Young's modulus were calculated for the results. These results were then compared and verified with those from the literature, with some of the fibers showing distinctly promising potential. Additionally, a study on the effect of alkalization using 3% NaOH solution was carried out on flax, kenaf, abaca, and sisal to observe impact that this common fiber pre-treatment process has on fiber mechanical properties. The result of the investigation indicated that over treatment of natural fibers using NaOH could have a negative effect on the base fiber properties. It is consequently apparent that a treatment time of less than 10 min is sufficient to remove hemicelluloses and to give the optimum effect
