BMS College of Engineering is an autonomous engineering college in Basavangudi, Bangalore, India. The engineering college, started in 1946 by BM Sreenivasiah, was one of the first private sector initiatives in technical education in India and is run by the BMS Educational Trust today. It is located on the Basavangudi Area Bull Temple Road, opposite to the famous Bull Temple. Though a private engineering college, it is partially funded by the Government of Karnataka.BMSCE has the largest student population among the engineering colleges in Karnataka, drawing students from other states of India and abroad. One of the oldest engineering colleges in Karnataka, it celebrated its "Diamond Jubilee" in 2006. It is also known for the annual inter-collegiate Techno-Cultural festival UTSAV, one of the prominent student-managed festivals in the country.BMSCE has also been the university champions under VTU for the most number of times by any college under the University . It is among the top 10 engineering colleges in Karnataka. In 2011 in university examination it topped with 32 Ranks Wikipedia.

Rammed earth is used for load bearing walls of buildings and there is growing interest in this low carbon building material. This paper is focused on understanding the compaction characteristics and physical properties of compacted cement stabilised soil mixtures and cement stabilised rammed earth (CSRE). This experimental study addresses (a) influence of soil composition, cement content, time lag on compaction characteristics of stabilised soils and CSRE and (b) effect of moulding water content and density on compressive strength and water absorption of compacted cement stabilised soil mixes. Salient conclusions of the study are (a) compaction characteristics of soils are not affected by the addition of cement, (b) there is 50% fall in strength of CSRE for 10 h time lag, (c) compressive strength of compacted cement stabilised soil increases with increase in density irrespective of moulding moisture content and cement content, and (d) compressive strength increases with the increase in moulding water content and compaction of CSRE on the wet side of OMC is beneficial in terms of strength. © 2010 RILEM.

If the battery of a node is drained out, then it cannot be communicated with other nodes and the number of dead-nodes makes the network partition. In order to overcome this problem, we propose a new routing algorithm for mobile ad hoc networks. It uses the residual battery capacity, transmission power, and hop-count to route the data packet. Here the proposed model has simulated with the help of 100 mobile nodes using the network simulator and has tested under various conditions. It compares with the ad hoc on-demand distance vector protocol, minimum total transmission power, and min-max battery cost routing models. The proposed model has shown better results in terms of node lifetime and network lifetime. The mobile nodes start to die at 400, 420, 440, 470, and 508 s for AODV, MTPR, MMBCR, CMMBCR, and proposed models, respectively. If the system has 145 J, then the AODV model transmits 38 000 of data packets, whereas the MTPR, MMBCR, CMMBCR, and proposed models will transmit 37 600, 47 240, 41 580, 42 700, and 42 955 of data packets, respectively.

Mobile Ad Hoc Network (MANET) is a decentralised network, which consists of mobile nodes. In this paper, we propose an efficient routing algorithm for the MANETs. Here, we use two metrics namely minimum total transmission power and network connectivity over the network. The proposed work has been simulated using .Net and has compared with the existing algorithms such as DSR, Minimum Total Transmission Power Routing (MTPR) and Min-Max Battery Cost Routing (MMBCR). The simulation results have proved that the proposed model has reached at top position in terms of the number of nodes with zero-remaining energy and throughput. If the mobility of the node is 25 m/s, then the proposed model, MTPR model, MMBCR model and AODV model have transmitted 68%, 50%, 59% and 62% of the data packets, respectively. At 700 s, the number of nodes with zero-remaining energy in the proposed model is 5, whereas in the AODV model, MTPR model and MMBCR model the number of nodes with zero-remaining energy was 39, 22 and 7, respectively. © 2011 Inderscience Enterprises Ltd.

A linear stability analysis of convection in viscoelastic liquids with temperature-dependent viscosity is studied using normal modes and Galerkin method. Stationary convection is shown to be the preferred mode of instability when the ratio of strain retardation parameter to stress relaxation parameter is greater than unity. When the ratio is less than unity then the possibility of oscillatory convection is shown to arise. Oscillatory convection is studied numerically for Rivlin-Ericksen, Maxwell and Jeffreys liquids by considering free-free, rigid-rigid and rigid-free isothermal/adiabatic boundaries. The effect of variable viscosity parameter is shown to destabilize the system. The problem reveals the stabilizing nature of strain retardation parameter and destabilizing nature of stress relaxation parameter, on the onset of convection. The Maxwell liquids are found to be more unstable than the one subscribing to Jeffreys description whereas the Rivlin-Ericksen liquid is comparatively more stable. Free-free adiabatic boundary combination is found to give rise to a most unstable system, whereas the rigid isothermal rigid adiabatic combination gives rise to a most stable system. The problem has applications in non-isothermal systems having viscoelastic liquids as working media. © 2009 Elsevier Masson SAS. All rights reserved. Source

Improper urbanization and industrialization are causing a critical stress on groundwater quality in urban areas of the developing countries. The present study under investigation describes the pollution caused by leachate from a waste management site in southwestern Bangalore city causing pollution of the surface water and groundwater reserves. The characterization of 20 groundwater samples and Haralukunte lake sample indicated high pollution of these water reserves by leachate entry into the groundwater and surface water sources. The study area focuses around the solid waste management site, carrying out bio-composting and vermi-composting of municipal solid waste. Further investigations on the severe health problems faced by the public in the study area has revealed a clear pointer towards the usage of polluted water for rearing live-stock, farming, and domestic activities. The characterization of the leachate with high values of BOD at 1,450 mg/l, TDS at 17,200 mg/l, nitrates at 240 mg/l, and MPN at 545/100 ml indicates a clear nuisance potential, which has been substantiated by the characterization of lake water sample with chlorides at 3,400 mg/l, TDS at 8,020 mg/l, and lead and cadmium at 0.18 and 0.08 mg/l, respectively. Analysis of groundwater samples shows alarming physicochemical values closer to the waste disposal site and relatively reduced values away from the source of the waste management site. Bureau of Indian Standards have been adapted as the benchmark for the analysis and validation of observed water quality criteria. © 2010 Springer Science+Business Media B.V. Source
