A Review on the Bioremediation Process for the Removal of Heavy Metals
-Nandini M R ; Udayashankara.T.H; Madhukar.M
Globally, environmental pollution is increasing carelessly on account of an unabated increment in population, industrialization, urbanization, anthropogenic activities and natural sources. Among various pollutants, heavy metals are released into soils and water from industrial operations such as smelting, mining, metal forging, manufacturing of alkaline storage batteries and combustion of fossil fuel. Moreover, the agricultural activities like application of agrochemicals and sewage sludge in agricultural fields also add a considerable amount of metals in the soils. However, heavy metals like zinc, copper, cadmium, lead, mercury and nickel have been reported as the most toxic pollutants. The metal pollution is of great concerns, as these hazardous pollutants are accumulated in living organisms including microorganisms, plants, animals and human and are responsible for many metabolic and physiological disorders. Many techniques for remediation of contaminated soil have been developed, such as physical, chemical degradation, photodegradation. However, most of these methods have some drawbacks in completely remediating contaminated soil. Biological treatment offers the best environmental friendly method for remediating heavy metal contaminated soil because it utilizes the capability of the indigenous microorganisms in the soil environment to break down the heavy metals into innocuous substances.

Energy Efficient Routing in WSNS Using MSDA
-Simple Preet Kaur Maan ; Dinesh Kumar
In WSN, sensor nodes operate on battery and it’s difficult to recharge or change the batteries. Thus energy proficiency is the main issue in WSNs. One of the techniques to this hindrance is clustering. Improved Energy Efficiency semi static clustering protocol (IEESSC) is an energy aware protocol in which clustering is done based upon the residual energy. It uses the concept of single mobile sink moving randomly throughout the network. In this paper, a new routing protocol based on child sink nodes concept i.e. Energy Efficiency Routing in WSNs using MSDA (Multiple Sinks Divisional Approach) is proposed. This protocol is simulated and compared with IEESSC based upon the parameters setup time, routing overhead and throughput. Simulation results demonstrate that proposed protocol has better results as compared to IEESSC. Read More...

Web Based High Accuracy ECG Detection and Healthcare System
-Mayur A. Gurule ; R.R. Bhambare
In the field of health care systems like ECG detection, the system requires high accuracy and low data losses. But in achieving both of these goal, the system gets much complicate. This paper presents the design of web based embedded programmable ECG monitoring system and detection of ECG characteristic points using joint QRS detection and data compression technique implemented using ARM 7 processor. The system also detects and monitors the other important parameters related to the human body, such as blood pressure and body temperature and displays it on the LCD screen. This detected ECG waveform and other body parameters are transmitted to local host and then to internet server using web based system by which anyone could monitor the patient's health condition wirelessly. This system is expected to work more conveniently and accurately for the doctor to monitor the patient’s condition sitting in his own office without being physically present near to the patient’s bed. A low-voltage and high performance analog signal conditioning circuit is built to insure high signal quality. A joint approach for QRS detection and lossless data compression (JQDC) would result in lower overall system complexity. By sharing the computational load among multiple essential signal-processing tasks, the average complexity per task can be kept at low level. An adaptive linear data prediction scheme based algorithm is used for joint QRS detection and lossless data compression, which achieves high sensitivity and positive prediction (+P). Lower system complexity and better performance will make this algorithm suitable for portable ECG application. The web based wireless transmission technique is used so that the detected human body parameters can be transmitted to the doctor remotely. The system is built using ARM 7 processor which ensures high accuracy performance and consistent result in the timing operation of the system. Read More...

Performance Analysis of Image Smoothing Filters
-Amandeep Kaur ; Ashish Verma
Digital images plays very significant role in day-to-day activities along with the areas of research and technology. But the main drawback of digital images is that noise added during their transmission. De-Noising of images can be carried out by several techniques. But before that we have to learn about the concept of denoising. Denoising is very leading affair in the field of image processing. Image denoising is the process of recuperating the primary image from an observation that has been depraved by various noises. In this paper several techniques are suggested for image de-noising and individual techniques is capable in removing noise with edge preservation and less computational complexity is presented. Many smoothing filters have been introduced vary from simple mean to more complex filtering Such as bilateral filtering. These filters aim at smoothing the image to eliminate some form of noise.
The proposed method is an optimum solution for these requirements. The performance of the algorithm is tested and compared with standard mean filter, median filter, weighted median filter, gaussian filter, bilateral filter and recently proposed filter. Experimental results show the remarkable performance of the proposed filtering technique compared to the other classic techniques in terms of both subjective and objective evaluations.

Power Saving Data Aggregation Approach in WSN
-Anchal Rani ; Sarita Chaudhary
This Paper Presents the wireless routing in sensor networks, data aggregation has been proposed as a predominantly constructive prototype. Most of the routing algorithms for traditional networks are address centric, and the ad hoc nature of wireless sensor network makes them unsuitable for practical applications. Data-centric technologies that carry out in-network aggregation of data to capitulate energy-efficient dissemination are essential. In our thesis work, we have implemented another approach to effectively deliver the data to the sink. In this approach, the sink will broadcast an interest message containing its required data model, to all the nodes. When the aggregator receives the data from the sources, it aggregates the data depending on the interest message using spatial and temporal convergence. Address Centric protocols and Data-Centric Protocols are the two kinds of sensor routing protocols. Read More...

Heat Transfer Enhancement in Turbines using Dimples- a CFD Study
-Nitish Kumar Jain ; Dr.U.S. Mallikarjun
In order to increase the efficiency and the specific power of gas turbine engines, the turbine inlet temperature study is very important. The current rotor inlet temperature level in advanced Gas turbine is far above the melting point of the blade material. Therefore along with high temperature material development a sophisticated cooling scheme must be developed. Nevertheless, material progresses are not sufficiently important to guarantee an economically acceptable life span of the components, in contact with the hot gases. So recently research is focused on turbine blade cooling. The blades are cooled in different ways such as using cooling holes, ribs, grooves, dimples, and many more. Dimples are the depression created on a surface which generate extra strong vortex flows near the wall beneath the main flow region downstream the dimples, which distinctively increases the turbulent mixing there and enhance the heat transfer rates. In the present study, the effects on heat transfer due to dimples are studied by creating five dimples in a rectangular channel. The work is carried out for different dimple depths (δ/D=0.23 to 0.26) and at different Reynolds number varying from 7500 to 27500. The computational study is carried out using NUMECA FINE/Open commercial code using k-ε (Extended wall function) turbulence model. Results show that at higher Reynolds number the Nusselt number increases as the dimple depth is increased and at lower Reynolds number (i.e. lesser than 22500) the Nusselt number varies non-uniformly. The dimple depth to diameter ratio δ/D =0.25 gives the best results as the Nusselt number is high at all Reynolds numbers compared to other dimple depths. Read More...

Prevention of Byzantine Attack by Large Wireless Sensor Network
-Vanmathi M
This paper explores reliable data fusion in mobile access wireless sensor networks under Byzantine attacks. The q-out-of-m rule, which is popular in distributed detection and can achieve a good trade-off between the miss detection probability and the false alarm rate. However, a major limitation with it is that the optimal schema parameters can only be obtained through exhaustive search, making it infeasible for large networks. In this paper, first, by exploiting the linear relationship between the schema parameters and the network size, proposed simple but effective sub-optimal linear approaches. Second, for better flexibility and scalability and derive a near-optimal closed-form solution based on the central limit theorem. Third, subjecting to a miss detection constrain, prove that the false alarm rate of q-out-of-m diminishes exponentially as the network size increase, even if the percentage of malicious nodes remains fixed. Finally, propose an effective malicious node detection schema for adaptive data fusion under time-varying attacks; the proposed schema is analyzed using the entropy-based trust model, and shown to be optimal from the information theory point of view. The proposed approaches under both static and dynamic attacks. Read More...

Seismic Analysis of Multi-Storeyed Building with Underneath Satellite Bus Stop and Intermediate Service Soft Storey Having Floating Columns
-Shrikanth Bhairagond ; Prof Vishwanath .B. Patil
Generally masonry infill walls are considered as non-structural elements and their stiffness contributions are ignored in the analysis when building is subjected to seismic loads. RC frame building with open ground storey is known as a soft storey, similar soft storey effect can be observed when soft storeys at different levels of structure are constructed. From the past earthquake it has been observed that a building with discontinuity in the stiffness and mass subjected to concentration of forces and deformations at the point of discontinuity which may leads to the failure of members at the junction and collapse of building. Most economical way to eliminate the failure of soft storey is by adding shear walls to the tall buildings. Hence in this paper attempt has been made to study performance of a building with soft storey at GL along with at intermediate level of building with floating columns, type of shear wall in seismic prone areas. The effectiveness of RCC shear wall building is studied with help of ten different models. Analysis is carried out by ETABS software.

Effect of Dilution hole Geometry on Gas Turbine Combustor Pattern Factors-A CFD Study
-Yathisharadhya ; Dr. H.R.Purushothama
The quality of hot gases originating from gas turbine combustor is measured using two parameters viz., circumferential pattern factor and radial pattern factor. These parameters have a direct effect on the life of turbine vanes and blades and ideally they should be as small as possible. A higher total pressure loss in the combustor liner reduces the pattern factors but from the engine overall performance perspective, it has to be a minimum, as every one percentage increase in total pressure loss results in a half percent reduction in thrust and around a quarter of a percent increase in specific fuel consumption. Among all the variables that influence the pattern factors, the dilution hole area significantly alters the pattern factors. In the present work, CFD analyses have been carried out to estimate the effect of dilution hole geometry on gas turbine combustor pattern factors. During this process, it has been ensured that the total pressure remains unaltered. Analyses have been carried on 20 degree sector of combustor geometry using CFD code “Fluentâ€. The modifications carried out to the dilution hole geometry were categorized into three groups. Turbulent reacting flow analyses have been carried out using steady state RANS model. The liquid fuel has been modelled as a discrete phase. A reduced two step reaction is used to model the chemistry; turbulence has been modelled using realizable k-epsilon model and combustion by the laminar flamelet model (non premixed combustion model). The flow field characteristics within the combustor, pressure loss, mass flow distribution, maximum temperature and pattern factors at the combustor exit were extracted and reported. It is found that even through the dilution hole remains unaltered, the disposition of dilution holes effects the pattern factors significantly. Read More...

Energy consumption is rapidly increasing due to population growth, higher standard of living and increased production. Significant amounts of energy resources are being consumed by the transportation sector leading to the fast depletion of fossil fuels and environmental pollution. Biodiesel is one of the technically and economically feasible options to tackle the aforesaid problems. In this research work biodiesel will be produced by trans-esterification of crude Rice Bran Oil (RBO).And the analysis of C.I engine will be done by using the diesel fuel and also by utilizing the blend of biodiesel –diesel .Oil extracted from the inner husk of rice, termed Rice Bran Oil (RBO) promises to be a low-cost, renewable substitute for petroleum-derived diesel as a compression ignition (CI) engine fuel. While rice is a major crop in India, RBO is underutilized. As an oxygenated fuel, RBO reduces emission of pollutants like CO and unburnt hydrocarbon (UBHC) by supplying additional oxygen from the fuel. The specific objective of this study is to analyse the performance, and emission characteristics of RBO and its blends with diesel. Results showed that biodiesel obtained under the optimum conditions has comparable properties to substitute mineral Diesel and is found suitable to use as a substitute fuel in the C.I engine asits fuel consumption rate, Brake Specific Fuel Consumption (BSFC) and Brake Thermal Efficiency (BTE) is very close to that of conventional diesel fuel.

Multiple Level Cache Performance Improvement Method
-Ms. Komal S.Thakre ; Prof. Shyam P. Dubey; Prof. Nilesh Choubey
Distributed or parallel system is known for their performance. To improve the performance of an I/O system, there is a great demand in multilevel cache over a single cache because of its efficiency. Many policies of multilevel cache are present still there is a performance issue. 1) These policies fail to select optimally cache block for replacement i.e. fail to select a victim and 2)increases redundancy causes cache pollution at lower level. These policies include LFU, LRU-K, PROMOTE, DEMOTE, Multi Queue (MQ). In this paper we introduced Reputation cache management policy which will address drawbacks of above defined policies by considering three factors together to replace or update cache block in a multilevel cache hierarchy, secondly it prevents cache pollution at lower level cache. First factor is recency of object in a cache i.e. how nearly object is used, second is frequency i.e. How repeatedly promotion and demotion of cache block takes place in a cache. Third is considering object size, the object with largest block size and less recency and frequency will be evicted first. This policy is capable of selecting a cache block efficiently and thus gives higher hit ratio compared to other present multilevel cache policies. Read More...

Design of Water Treatment Plant using Abandoned Quarries in Malayankeezhu Panchyat in Thiruvananthapuram District, Kerala
-Milan M. R. ; Dr. Lokesh K. S.
At present the level of water supply is not adequate in the different place coming under the scheme area. There is no major scheme, which is in operation in this area to cater to the existing demand. Localized schemes are in operation for providing water supply in various areas. The existing schemes are small and supply is only 3 days in a week, locally centered to feed some particular areas of the panchayaths. They are not properly designed and hence further extension or augmentation is not possible for these schemes. The other areas of these panchayaths have to depend on public and private open wells which will dry up during summer months. Also the treatment adopted is only chlorination by adding bleaching powder. Hence the quality of water is poor due to lack of proper treatment. The recurring charges like establishment expense and electricity charges also get reduced if a comprehensive scheme is worked out. The existing distributions of all schemes are very old and in dilapidated condition. Area consists of around 50 abandoned quarries which leads to poor runoff and reduced water levels in open wells.

Position Update in Mobile Ad-hoc Network
-Sapna ; Naveen Goel
The Ad-hoc networks come to be very widespread. Everybody is using these networks because the decentralized nature of wireless ad hoc networks.Wireless ad hoc networks makes them suitable for a variety of applications where central nodes can't be relied on and may improve the scalability of networks compared to wireless managed networks. Though theoretical and practical limits to the overall capacity of such networks have been identified. In geographic routing, nodes need to maintain up-to-date positions of their immediate neighbors for making effective forwarding decisions. We contend and demonstrate that periodic beaconing regardless of the node mobility and traffic patterns in the network is not attractive from both update cost and routing performance points of view. In this, we propose the Adaptive Location Update strategy for geographic routing. Which dynamically adjusts the frequency of position updates based on the mobility dynamics of the nodes and the forwarding patterns in the network. And resolve the Unknown node problem when it exist to increase the efficiency of this method by introducing the phenomenon of selecting node from existing ones or unknown node. Read More...

Seismic Analysis of Multi-Storeyed Building with Underneath Satellite Bus Stop and Top Soft Storey with Different Types of Shear Wall
-Galanna ; Vishwanath.B.Patil
Normally masonry infill’s are considered as non-structural elements and also their stiffness contributions are generally ignored in practice. And also they affect both the structural and non-structural performance of the RC buildings during earthquake. RC frame building with open first storey is known as soft storey, which performs poorly during strong earthquake shaking. A similar soft storey effect can occur if first and top story used as service story. So that a combination of two structural system components i.e. The Rigid frames and RC shear walls leads to a highly efficient system in which shear wall resist the majority of the lateral loads and the frame supports majority of the gravity loads. To study the effect of masonry infill with different soft storey level, and also we were studying 10models of Reinforced Concrete framed building were analyzed with 7 types of shear wall when subjected to earthquake loading. The results of bare frame ,strut frame and other building models have been compared, it is observed that all models with L –type, swastika –type, plus(+)-type, I-type, C-type, U-type ,T-type shear wall with showing efficient performance and hence reducing the effect of soft storey in model 4, model 5 ,model 6,model 7,model 8,model 9 model 10.
