Effect of Bracings on Multistored RCC Frame Structure Under Dynamic Loading

Braced frames are known to be efficient structural systems for buildings under high lateral loads such as seismic or wind loadings. The potential advantage of bracing system is that it is comparatively small increase in mass associated with the retrofitting scheme since this is a great problem for several retrofitting techniques. In this study building modeling is done for regular and vertical irregular building with and without bracing system. Response spectrum analysis is done for each model with different types of bracings. The results in terms of displacement, storey drift, storey shear of regular and irregular structure is compared.

Synthesis of Zirconium Phosphosilicate and its Application as Inorganic Ion-Exchanger for Adsorption and Radiochemical Separation of Indium(III)

In the present investigation zirconium phosphosilicate has been synthesized and characterized for its composition. A rapid and selective method has been developed for the radiochemical separation of In (III) from other elements by adsorbing it on zirconium phosphosilicate as an ion-exchanger by batch process. 114mIn is used as a tracer. The optimum time of contact and pH for the adsorption of 1 mg of In (III) has been found to be 5.0 min and 4.0 respectively. The adsorption was found to be maximum (94.48 ±2.8%) with 200 mg of the exchanger. The interference of various anions in the adsorption of In(III) at optimum condition of adsorption has been studied. Adsorption of various other cation in presence of In(III) also has been studied. The distribution co-efficient values and the Decontamination factor has been evaluated.

Biosorption of Heavy Metal Using Bacteria Strain and Its Optimization

Soil and water pollution is becoming one of major burden in modern Indian society due to industrialization. Though there are many methods to remove the heavy metal from soil and water pollution but biosorption is one of the best scientific method to remove heavy metal from water sample by using biomolecules and bacteria. Biosorbent have the ability to bind the heavy metal and therefore can remove from polluted water. Currently, we have taken the water sample from Ballendur Lake, Bangalore. Which is highly polluted due to industries beside this lake. This sample of water was serially diluted to 10-7. 10-4 and 10-5 diluted sample were allowed to stand in Tryptone Glucose Extract agar media mixed with the different concentrations of lead acetate for 24 hours. Microflora growth was observed. Then we cultured in different temperature, pH And different age of culture media. Finally, we did the biochemical test to identify the bacteria isolate and we found till genus level, it could be either Streptococcus sp. or Enterococcus sp.

Human factors in Safe Construction of Mega Projects in India

Construction is a hazardous process, which is responsible for severe and fatal accidents around the world. The global studies on Occupational Health and Safety (OHS) aspects in the construction industries also reiterated for the improvement of safety culture. The mega projects are projects characterized by vast capital, unorganized work force, technically complex constructions, and having a significant impact on the socioeconomics and community development. For example; highways, power projects, residential buildings, airports, industrial parks, etc. The construction industry is mainly skill oriented and labor intensive. This paper is aimed at studying the prevailing safety practices in the construction of infrastructure power projects in various regions in India in the past 15 years. The study mainly focused on a survey of human practices which are responsible for the behavior at work. The unsafe acts/conditions at work place when uncontrolled lead to incidents/ accidents. The elements identified in the construction process are factored and a safety culture model is developed. The model is based on rock-bottom principles, rigorous approaches and rigid hazard management practices, which is suitable for the construction industry.

Seismic Effect of Masonry Infill with Open and Shear Wall on Flat Slab Structures

In the design of tall structures it is essential that the structure must be enough stiff to resist the lateral loads caused by wind and seismic motion. Lateral loads leads to develop high stresses, produce sway movement or cause vibration. Therefore, it is a must for the structure to have sufficient strength against vertical loads together with adequate stiffness to resist lateral forces. Many researches has been carried which describes the suitability of various lateral load resisting system against deformation and shear exerted due to the seismic and wind forces. The RC structures with shear wall and MI frame have been recognized as one of the most efficient structural system for such a purpose. A flat slab is a typical type of construction in which a reinforced slab is built monolithically with the supporting columns and is reinforced in two or more directions, without any provision of beams. Flat slab structures in areas of low seismicity (Zone I & II) can be designed to resist both vertical and lateral loads as permitted by code IS: 1893(Part1)-2002. However for areas of high seismicity (Zone III, IV & V) code does not permit flat slab construction without any lateral load resisting system. In a building having frames (without beam) and with shear wall, the frames are designed for at least 25% of the seismic force and 75% is taken by the shear wall. If effect of lateral load analysis and other design features are to be studied in flat slabs; punching shear is a matter of concern for any structural designer.

Automatic Detection of Diabetic Retinopathy using Deep Convolutional Neural Network

The purpose of this project is to design an automated and efficient solution that could detect the symptoms of DR from a retinal image within seconds and simplify the process of reviewing and examination of images. Diabetic Retinopathy (DR) is a complication of diabetes that is caused by changes in the blood vessel of the retina and it is one of the leading causes of blindness in the developed world. Currently, detecting DR symptoms is manual and time-consuming process. Recently, fully-connected and convolutional neural networks have been trained to achieve state-of-the-art performance on a wide variety of tasks such as speech recognition, image classification, natural language processing, and bioinformatics. In our approach, we trained a deep Convolutional Neural Network model on large dataset consisting around 35,000 images and used dropout layer techniques to achieve higher accuracy.
