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.

In a multi-hop WSN a sensor node spends most of its energy for relaying data packets due to which energy reduction is one of the major issue in the designing of a wireless sensor network to prolong the lifetime of a network. One of the solutions of this problem is to shorten the hop distance a sensor's data that has to travel until reaching the sink. These distances can be reduced effectively by deploying multiple sinks instead of one and every sensor communicates with its closest sink. In order to achieve the shortest distances the sinks have to be deployed carefully. In this paper we have considered the problem of optimal deployment of k sink nodes in a wireless sensor network for minimizing average hop distance between sensors and its nearest sink with maximizing degree of each sink node which can solve hot spot problem which is another critical issue of WSN design. Given a wireless sensor network where the location of each sensor node is known, partition the whole sensor network into k disjoint clusters and place sink nodes optimally. We propose multi sink placement algorithm, based on Particle swarm optimization. The simulation results show that our proposed optimization based algorithm perform better over algorithm without optimization. © 2013 IEEE.

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.

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.

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.

In this study, the author investigates the problem of lifetime enhancement of mobile nodes in mobile ad hoc networks. Here, the author uses two metrics namely, residual battery capacity of the node and non-critical node to route the data packets from the source to the destination. The proposed model uses the non-critical node if all the nodes contain residual battery capacity above the threshold value. The proposed model has been simulated using Qualnet Simulator-4.5. The proposed model has compared against the existing algorithms such as minimum total transmission power routing, conditional max-min battery capacity routing and lifetime prediction routing. From the results, the author concludes that the proposed model has reached at the top position in terms of the number of survived nodes, energy saving and number of nodes with zero remaining energy. © 2011 © The Institution of Engineering and Technology.

Wireless ad hoc networks are growing important because of their mobility, versatility, and ability to work with fewer infrastructures. The mobile ad hoc network is an autonomous system consisting of mobile nodes connected with wireless links. Establishing a path between two nodes is a complex task in wireless networks. It is still more complex in the wireless mobile ad hoc network because every node is no longer as an end node and an intermediate node. In this paper, it focuses on design of connectionless routing protocol for the wireless ad hoc networks based on the mobile agent concept. The proposed model tries to discover the best path taking into consideration some concerns like bandwidth, reliability, and congestion of the link. The proposed model has been simulated and tested under various wireless ad hoc network environments with the help of a different number of nodes. The results demonstrate that the proposed model is more feasible for providing reliable paths between the source and destination with the minimum control message packets over the network. It has delivered more number of packets to the destination over the network. Copyright © 2012 John Wiley & Sons, Ltd.

A mobile ad hoc network is a dynamic wireless network, which does not have fixed infrastructure. This paper presents a new multicast algorithm to increase the lifetime of node and network in the mobile ad hoc network. Here, it considers two metrics, namely residual-battery-capacity of the node and relay-capacity of the node to do multicasting from the source to a group of destination nodes. The proposed model is simulated using network simulator-2.33 and is tested under various conditions. The proposed model is compared with the existing algorithms such as multicast-incremental-power, lifetime-aware- multicast-tree, multicast-ad-hoc-on-demand-distance-vector protocol and multiple-path-multicast-ad-hoc on-demand vector. The proposed model shows the best results in terms of node lifetime, network lifetime and throughput. © 2001-2012 IEEE.

This paper focused on the design and implementation of a sliding mode controller with fuzzy logic tuning for depth control of an autonomous underwater vehicle (AUV). A fuzzy tuning approach to sliding mode control is employed for enhancing the tracking performance as well as reducing reaching time. The sliding surface can rotate or shift in the phase space in such a direction that the tracking behavior can be improved, which can be carried out using fuzzy tuning method. The reaching time and tracking error in the approaching phase can be significantly reduced. Experimental results indicate the effectiveness of the proposed controller in dealing with model uncertainties, nonlinearities of the vehicle dynamics and environmental disturbances caused by ocean currents and waves.
