Evolve of Technology with Biofuel for Transportation
-Soumi Pramanik ; M C Chattopadhyay
When “biofuels†became a catchphrase from a word, hopes are soaring for us that it is the end of high-priced oil and environmental problems will finally come to an end. Politicians, farmers, consumers and environmentalists are slowly realising that the situation is far more complicated. Biofuel has big capabilities and there is a valid reason to peruse it. However, the current biofuel production models are not working, there are more sustainable and more efficient biofuels options on the horizon. The major trouble is that the lack of technology and the expenses required to process these materials, makes existing mass-production impossible. The relevant question for this 21st century is how to utilize biofuels without hurting consumers or the environment. Legislation should be reflective of the current and future realities of the biofuels industry. The aim of this paper is to analyse Technology Roadmap: Biofuel for Transportation. Read More...

-Nagaraja B S ; Hemalatha M; Dharmesh N; Madhusudhana Y B
Masonry infill frames are the most common structural systems in earthquake regions. They play a significant role in resisting seismic forces when earthquake happens. The stiffness and strength contributions of infill frames are generally neglected during practice. They are considered as non-structural components and usually added after the frame has constructed. In the present study, two buildings of G+3 and G+12 are considered for seismic zone v consisting hard soil for the analysis. Totally 7 models are made for the analysis using software ETABS version 2013. The response parameters of 7 Models such as Base Shear, Mode Period, Storey Displacement, Storey Accelerations and Storey Shear are studied and comparisons are made for both Equivalent static lateral force method and Time history analysis. As the height and mass participation of the structure increases, Base Shear and Mode Period also increase. If percentage of opening increases, the stiffness reduces. Simultaneously but the Mode period and Displacement increases and frequency reduces due to which acceleration decreases for both G+3 and G+12 Buildings. Compared to ESLM and TH analyses, the Time history analysis shows better performance than Equivalent static lateral force method and G+3 building shows lesser displacement compared to G+12 Building.

Speed and Position Control of Stepper Motor using 8051 Microcontroller
-Amit Kumar ; Ramjee Prasad Gupta
Speed control of machine is the most vital and important part in any industrial organization. This research work focuses on speed and position control of stepper motor using 8051 microcontroller. The speed of stepper motor has been controlled by the delay between consecutive pulses of stepper motor phases provided by microcontroller. Actually speed is inversely proportional to delay between pulses of consecutive phases and Position of stepper motor has been controlled by the number of revolutions. In this project work step angle of 15 degree per step has been taken when motor is moving in clockwise direction and 7.5 degree per step when moving in anticlockwise direction. The direction of movement of stepper motor depends on opening and closing of switch. When switch is closed, motor moves in clockwise direction and when switch is opened, motor moves in anticlockwise direction. Furthermore, variable resistor connected to pin no. 6 of ADC has been varied in clockwise direction due to which speed increases and when varied in anticlockwise direction speed decreases. In this project work infrared sensor has been used to detect speed of stepper motor in rpm. Speed in rpm & step angle in degree has been displayed on LCD screen and output pulses can be observed on CRO. The control program has been written in assembly language and Kiel compiler has been used to convert this control program into executable file or in a HEX code. This hex code has been burnt into microcontroller by Flash Magic software. Read More...

-Manikandan S ; S.Settu; M.Krishnamoorthi
In this study the American Iron and Steel Institute(AISI) 4140 steel produced by Powder Metallurgy route. The specimen dimensions were maintained as per the standard dimensions needed for conducting the wear test by using the pin on disc wear analysis. The hardness of the AISI 4140 Powder Metallurgy steels was improved by quenching process. The quenching process was carried out at the temperature of 9000 C for 1hr and 2hr respectively. The wear resistance model for AISI 4140 P/M steel was developed in terms of quenching time, applied load, sliding distance and sliding speed using the Taguchi method. The wear test was carried out and evaluated the sliding wear behavior such as wear rate of sintered and quenched AISI 4140 Steels by using pin on disc wear tester. The orthogonal array and signal-to-noise (S/N) ratio are employed to investigate the optimal testing parameters. The experimental results demonstrate that the quenching time was the major parameter among the controllable factors that influence the weight loss of AISI 4140 P/M steel. For AISI 4140 P/M steel, the quenching time had the greatest effect on the wear, followed by applied load. The sliding distance and sliding speed had a much lower effect. The optimal combination of the testing parameters could be determined. Read More...

-Harpreet Singh ; Amanpreet Singh
Gears are the critical parts of transmission system. Gears are used to transmit power or torque through direct contact between paired gears. Global competition in automotive market has brought the awareness to optimize the transmission design by optimizing the gear pair without compromising with its life. An optimization consists of selection of proper material and face width of gear pair by keeping the bending stress within safety limit and also by keeping the size or weight of gear pair smaller as much it can be without compromising with its performance. The purpose of this study is to establish a relation between different materials and face widths with the help of bending stress calculations (As per ISO 6336-3), also with some help of computer software viz. Excel spreadsheet. Calculated curves show the relationship between different materials Vs Permissible bending stresses and maximum bending stresses Vs Face widths Vs Materials to select most suitable one as per application requirement. Curves also show increase in price with respect to increase in face width. With the help of these curves one can easily select material and face width as per their application. Read More...

-Megha Jain ; Mrs. Pushpa Singh
The paper presents a review on numerous ways in which of content based image retrieval. Content based image retrieval may be a system by that numerous images are retrie- ved from an outsized database assortment. These databases are ready using numerous visual features like color, texture, shape and spatial layout that are extracted using completely -different techniques. As image database volume is increasing rapidly, researchers are probing for a much better robust mech -anism to retrieve images and to get more accurate results. Therefore the analysis focus has been shifted from low-level feature extraction algorithms to the high get more accurate results. Therefore the analysis focus has been shifted from low -level feature extraction algorithms to the high level visual feature extraction mechanism. To develop better content based image retrieval system, it is necessary to boost numerous processes concerned in retrieval like feature extraction, image segmentation, image decomposition and similarity matching techniques. During this paper we tend to discuss the basic aspects, visual features and techniques for quick and retrieval images from the database. In this paper, completely different well-known options for image retrieval are quantitatively com -pared and their correlation is analyzed. We compare the options for two different image retrieval tasks (color a clear and medical radiograph) and a transparent distinction in per-formance is determined, which can be used as a basis for an appropriate selection of features. In the medical field, images, and especially digital images are produced in ever increasing quantities and used for diagnostic sand therapy. Read More...

Surface Water Quality Modeling: A Review of the Analysis of Uncertainty
-Smruti Sohani ; Pramod Ku. Singh; Sanjeeda Iqbal
After the origin of life in water everything of living organisms is sustained by water. Not only biotic components, abiotic components on the Earth depend on water. Water is not only essential to life but is predominate inorganic constituent of living matter forming nearly three quarters of the weight of a living cell. In short water is essential for life and plays a unique role virtually as medium in all biological process. This report showed an overview of the water supply situation in Indore. It was considered appropriate to undertake an independent assessment of the water supply to Indore as well as a review of all water demand management activities being undertaken in the supply area. The degree of pollution is assessed generally by studying physical and chemical characteristics of the water body. Any undesirable change in the physico-chemical characteristics of water brings about water pollution. This change is mainly due to human activity such as rapid urbanization and industrialization coupled with injudicious exploration of natural resources. The discharge of domestic sewage and industrial effluents into natural water resources such as rivers, streams as well as lakes and reservoirs results in alteration of their physical and chemical properties leading to objectionable conditions.

Role of VO2 MAX in Determining the Rest Period during Moderate Work
-Shara Khursheed ; Sumita Chaturvedi; Dr. K.M. Moeed
The ergonomics means fitting the job according to the workers capability. Ergonomically rest period is one of the basic factor in increasing the human comfort and reducing the risk of injuries. VO2 max is an criteria for determining the rest period which is based on the levelling of oxygen intake in the blood due to the increase in work rate, high level of lactic acid in the blood. With the increase of stress level maximal oxygen consumption also increase due to which demand for energy in the body increases and when our body is unable to supply such increasing demands than the condition of fatigue arises which ultimately leads to the musculoskeletal disorders, reduction in working efficiencies and other work related problems. The solution to such situation is providing the rest period. The aim of present study is to calculate the maximum oxygen consumption and the heart rate so to determine the optimum rest period in order to perform the task comfortably and efficiently.

-Sukhpreet Kaur ; Arun Kumar
This thesis aims at reducing energy consumption in wireless sensor networks. To achieve this, we considered Wind Driven Optimization algorithm (WDO) in the selection of Cluster Head (CH) in such a way so that its energy is used uniformly with delayed disintegration of network. For this purpose, the LEACH algorithm random clustering approach has been replaced by WDO clustering. The WDO based LEACH protocol has been compared with random LEACH, LEACH-C and K-MEANS algorithm. Various factor taken for comparison are network life in the form of number of rounds, no of dead nodes and no of packet sent to BS affect performance of routing algorithm in WSN. The performance of cluster based routing protocol shows some differences by varying life pattern among nodes and number of dead nodes. LEACH-C perform better in network disintegration criterion but it give less network life as compared to WDO based LEACH. In WDO which is made of both types of search capabilities performs better than other methods. Read More...

Thermal Analysis on Triple Effect Falling Film Evaporator
-Vanitha Dunna ; P. Srinivas Kishore
Evaporation is an operation used to remove a liquid from a solution, suspension, or emulsion by boiling off some of the liquid. It is thus a thermal separation, or thermal concentration process. When a single effect evaporator is used to produce a concentrated liquid or crystal the vapour generated is a by-product with a latent heat content that goes to waste. Multiple effect arrangements are designed to utilize this waste heat and reduce steam consumption and heating power. This is done by using the vapour generated in the first stage as the heat source in the second stage and heat source in third stage. In this paper varying the input pressures at inlet from 24 bar to 16 bar mass flow rate of distilled water at three different stages are estimated using mass balance and energy balance equations. Steam generation rates of triple effect forward feed evaporator at different stages are compared with single effect evaporator. Graphs are drawn to predict the variation of enthalpies, heat for evaporation mass flow rate of distilled water for a triple effect forward feed evaporator. Read More...

Utilization of Flyash and Sludge of Mysore Paper Mills for Agriculture
-Anusha.M.K ; Dr. D.Istalingamurthy
Flyash is the main dust generated mainly from fluidized bed boilers, where coal is fired in a finely crushed form to improve the combustion efficiency. Sludge is a hazardous by-product which requires safe disposal either in landfill or incineration. These are the common waste generated mainly by thermal power plants and industries that cause un avoidable problems like ground water contamination, health hazards, environmental pollution etc., but by utilizing this waste for agriculture can reduce this problem to some extent and also it’s economically feasible. Pot experiments were conducted at 10%,20%,30%,40%,50%,70%,90%,100% treatment levels with flyash and (10% FA + 10% ss + 80% soil), (20% FA + 20% ss + 60% soil), and (50% ss + 50% soil) treatment levels with sludge generated by Mysore Paper Mills, located at Bhadravathi. Two types of soil i.e. black soil and red soil and Lycopersicon Esculentum (Tomato) were used for this study. The physic-chemical parameters, heavy metal analysis, growth parameters were analyzed and checked for plant growth. The use of flyash in soil improved the plant growth by increasing the physic-chemical properties of soil. The Lycopersicon Esculentum showed a positive growth up to 30% amendment with flyash whereas the usage of sewage sludge did not give satisfactory results in turn it hindered the growth of plant.

-Shreya Verma ; Dr. S.M. Ali Javed; Indu Singh; Zainab Siddqui; Sachin Gupta
Soil is one of the most important components of the environment and proper management of land is very important to maintain its quality and sustained use. The soil contamination resulting from increasing release and accumulation of heavy metals in soil by industrial and other human activities cause serious threat to the functioning of components of ecosystem. Clean up or removal of pollutants from soil is very difficult task and time consuming, once contamination occurs. Soil washing is one of the few permanent treatment method to remove metal contamination from soil. Soil washing is a technology which is used to treat soils and sludges. Zinc ,chromium ,cadmium ,lead ,copper ,mercury ,nickel are considered as the most hazardous heavy metals .Soil washing provides a cost effective and environmentally proactive alternative to stabilization and land filling. This process not employed on soils that are contaminated with pesticides and volatile organic compound. Soil washing is a technique that uses liquids, usually water, to remove chemical pollutants from soil and sometimes water combined with chemical additives to scrub soils. This scrubbing cause removal of hazardous contaminants and concentrates them into smaller volume. Read More...

Throughput and End-to-End Delay Comparison in Wireless Sensor Network using BPR
-Narasimalu N S ; Dr. P.P.Patavardhan; Prof. R.R.Kulkarni
Any network should have the ability to operate in harsh environments despite of the constraints taken in WSN. One of the basic features of any sensor network is to monitor and sense the surrounding for communication between them but because of their limited capabilities, sensor nodes are susceptible to various sources of failures such as presence of anomalies, malware attacks, hardware failures and software corruption which can reduce nodes functionality and badly affect most WSN operations. The existing system methods like (BOUND HOLE and GAR)can be used to diminish these issues but their performance is bounded by some restriction, the solution is to BY-PASS the infected node dynamically using twin rolling balls technique. The identification of the infected node is done by the adopting the fuzzy data clustering approach which classify the node based on the anomaly detection with the help of threshold values. The BPR algorithm bypasses the infected node to reach the destination, increasing the performance of the network. The twin rolling ball concept is used to get the idea of stuck packets in the network. Thus, BPR provides better performance in terms of QoS parameters that is throughput, end-to-end delay and energy consumption as compared to existing system. Read More...
