 Abstract

Abstract: In wastewater engineering, one of the most sophisticated methods of wastewater treatment is the tertiary treatment and biological treatment. A large number of inputs in the form of capital investment and energy have been placed for few decades now for meeting up the wastewater treatment objectives. To compensate these costs, natural wastewater treatment technologies, particularly the application of aquatic plants for wastewater treatment have been considered for quite long. The ability of aquatic ecosystem, mainly the aquatic plants to carry out wastewater purification has been exploited and this forms one of the major principles for natural wastewater treatment technologies. This study, constitute of various underlying concepts and principles involved in the wastewater treatment using aquatic plants. The study also present the results obtained from the research study carried to investigate the treatment or removal efficiency of aquatic plants (water hyacinth and typha angustifolia) to remove pollutants from wastewater via constructed wetland technology.

 Abstract

Any structure should be designed in such a way that damages in the structure should be reduced during an earthquake which makes the building little uneconomical, because earthquake may or may not be occur in fixed time period it is a rare phenomenon. This paper is made to analyze and design G+6 building in different seismic zones of India using STAAD Pro. IS 1893(part1):2002 is use for earthquake force analysis. When we are going from zone II-zone V variations are increases. Variations include steel percentage, maximum shear force, maximum bending moment, maximum deflections etc.

 Abstract

Seismic design relies on inelastic deformation through hysteretic behaviour. During severe earthquakes the structural system undergoes extensive damage that result in high cost of repair. Research these days has elevated and surpassed common human instinct. One such research that backed structural systems to sustain tremors of earthquake is metallic braces. These components are predominantly the lateral force resisting system in any building structure. The installation of braces within a structure system will magnetize substantial part of destruction while the parent elements persist elastically with inferior inelastic deformation. Dissipation of seismic energy occurs through inelastic yielding and buckling of bracing member in tension and compression respectively. In the present work will be structured in a reinforced concrete G+7 storied moment resisting frame building which will be modeled using (Software for Analysis and Design) SAP-2000. The building will be modeled in accordance with the provisions prescribed by IS:1893 2016 part I. Three patterns of bracing will be fabricated on the peripheral frame of erection, where pattern being X, V and Inverted V. Both types of non linear analysis i.e. dynamic time history (NTH) and non linear static (pushover) analysis will be carried out to investigate the performance of building structure due to induced dynamic forces by ground excitation. Scrutinizing framework through pushover analysis structural elements will be provided with hinges in accordance with Federal Emergency and Management Agency (FEMA) 356 and NTH is conducted using accelerogram of different earthquake. Results for NTH will described in the form of storey displacement, storey drift, shear force, bending moment and energy dissipated by frame and bracing. Whereas pushover analysis results will be quantified through different parameters like yield shear, yield displacement, target displacement and ductility ratio.

Abstract: Bisglycine Strontium Chloride (BGSC), a semi-organic newly synthesised crystal obtained by slow evaporation solution growth technique (SEST) using aqueous solution at ambient temperature. The unit-cell parameters of the grown crystal were confirmed by single crystal XRD. FTIR studies have been carried out for analyzing the presence of functional groups. The transparency of the grown crystal was identified by the UV-Vis spectrum. The dielectric constant (?r) and dielectric loss (tan?) as a function of frequency were measured for the grown crystal. The solid state parameters such as valence electron energy, plasma energy, Penn gap and Fermi energy were evaluated theoretically by using the empirical relation. The mechanical stability of the grown crystals was studied using Vickers micro hardness tester. The estimated values were used to calculate the electronic polarizability.

 Abstract

Cloud offers the provision for storing huge amount of data of clients, which would otherwise occupy a large amount of disk space in client's machine. The previous schemes of deduplication cannot work on data which is in encrypted format. The current deduplication scheme on encrypted data suffers from security weakness. Deduplication is necessary to avoid duplicate copies of users on cloud. Duplicate data on the cloud wastes a lot of network resources, leads to consumption of energy and complication in data management. So we propose a scheme to deduplicate the encrypted data present in the cloud. Data ownership challenge and verification will also be provided and access will be granted to the authorized user through proxy re-encryption. In this project we are focusing mainly on the data saving on cloud by saving our storage cost and energy.

 Abstract

Over the past several decades technology plays main responsibility in many homes around the world. Its influence has permeated into all facets of life, besides English language teaching. Integration of media and technology began in the 1950s when small language schools to use the phonograph, movies, and the tape recorder as tools in English language teaching. In the 1970s and 1980s, audio and video courses were improved through the added use of video projectors and slide shows. By the late 1980s and early 1990s, language labs were part of many of the more expensive language schools in the mode of educating the learners. However, by the mid 1990s many multimedia language programs became available for teachers and the learners on the Internet. In modern era of English language teaching, media technology such as video, pictures, the use of internet, chat rooms and video conferencing have tapering distance and turned the intact world. It affords opportunities to the learners to converse not only with local community but with global community as well. It has revolutionized learning and teaching methodologies thereby turning them more informative and productive.
