The present study undertaken in Cauvery delta zone and Southern zone in the state of Tamil Nadu has estimated the resource use efficiency in rice production and has assessed the effect of farm specific socio economic factors affecting the technical efficiency. A stochastic frontier production function was estimated to determine technical efficiency of individual farms. The data were collected for two years from the Cost of Cultivation Scheme of Tamil Nadu Centre. The results of Cobb-Douglas stochastic production function indicated that the estimated parameters for seed (positive), labour hours(negative) and value of pesticides (negative) are significant and hence, playing a major role in influencing rice production under canal irrigation. But in the case of tank irrigation system the estimated parameters for fertilizers, labour hours, machine hours are significantly and positively influenced the yield of paddy. Moreover the marginal value product to input price ratios for the variables influencing significantly revealed that it will be profitable to increase the use of seeds in canal irrigation and fertilizer and human labour in tank irrigation system. The Z test results indicated that there is a significant difference between the average technical efficiency estimates between canal and tank irrigation systems.Keywords

Sugar producing regions in India have more than 80 percentage groundwater irrigation through deep-well pumping. Whereas, NASA's gravity recovery and climate experiment satellites have revealed faster depletion of groundwater stocks in India. These areas are cultivating 93 percentage of sugarcane. This research is a comparative study and has attempted to estimate the economic value of irrigation water and the benefits of water and energy that can be saved through adoption of improved irrigation technologies. The economic value of each ha. cm of irrigation water for sugarcane was also worked out. Including additional area under irrigation with the water saved should be recommended only in safe and semi-critical regions to prevent 'rebound' effect.Keywords

The demand for fertilizers in India is being supplied with humongous import of fertilizer apart domestic production. The price of fertilizers both controlled (Urea 'N') and decontrolled (phosphorus 'P' and Potash 'K') are regularised by the Government with subsidy. Around 30 per cent of total subsidy bill in Union Budget (2014-15) is allocated for fertilizer subsidy in India. The study has the objective to impart the importance of fertilizer subsidy bill in India with reference to farmers and production of sugarcane. The study with the carefully forged research, attempted to find the private cost, social cost of fertilizer, Resource Use Efficiency (RUE) of essential nutrients with and without subsidy; and production loss when the subsidy is withdrawn by the Government. The fourth advances estimate of India on sugarcane production is 350.02 m. tones but when the subsidy bill on fertilizer is withdrawn then our production will be short by around 53 m. tonnes. To substantiate, the RUE will decline when fertilizer subsidy is withdrawn. Likewise, adoption per cent of drip irrigation will decline when micro-irrigation subsidy is withdrawn by the Government.Keywords

The present study was conducted to assess economics of marigold cultivation under contract farming vis-a-vis non-contract farming in erode district of Tamil Nadu and to examine the yield and price uncertainty, contractual arrangements in marigold cultivation. There were no price uncertainties in contract farming whereas there were very high price uncertainties in the case of noncontract farming. Farmers were satisfied with terms of contract. The major benefits to the contract farmers were assured buyer for the produce, all the produce can be sold even in case of damage and the farm gate collection. Important reason given by the former contract farmers for discontinuing cultivation of marigold on contract was low price for the produce.Keywords

In mobile ad hoc networks, all mobile nodes connect to each other via wireless, one of the important aspects of this type of network is the limitation of amount of available energy in the network nodes which is the most critical factor in the operation of these networks. And the tremendous amount of using the mobile nodes in wireless communication medium makes Energy Efficiency (EE) a fundamental requirement for mobile ad hoc networks. On the other hand Cluster Based Routing Protocol (CBRP) is a robust/scalable routing protocol for Mobile Ad hoc Networks (MANETs) superior to the existing methods [1-3] (For example it’s overhead of is less than while it’s throughput of is more than of AODV which is a standard protocol for MANET [4]. We added the resource management protocol to the CBRP for service advertisement and service discovery [5]. Although this protocol does not have significant overhead on the network it needs more consideration about increasing the life time and especially decreasing the energy consumption. We propose the idea of putting the idle member nodes to sleep state. The experimental results show that proposed method causes decreasing energy consumption in CBRP which results to stability of the network.

A real-time operating system (RTOS) is a piece of code (usually called the kernel) that controls task allocation when the microcontroller is operating in a multi-tasking environment. In the RTOS we selected OSA OS for our project. In our project we were controlling the industrial equipment with the help of the microcontroller. In this the major parts of industries were to be maintained. The controls were maintained are temperature management, entering into restricted area of the industry, emergency alarm and displaying such parameters. In the processing there are some ways of algorithm and processes were followed by the OS. The processes are 1) Context switching-while running a task switching to another task. 2) Multitasking-running more number of tasks at a time. 3) Interrupt handling-is the process of task with high priority will execute first by passing the running task. The algorithm were followed is that priority based system is that the task were executing with the priority bases the priority is given by us in the coding part. The tasks have the same priority that follow the round robin algorithm, it share the running time by separating equal time slots. For example two tasks of same priority it will run for 5ms and switched to another tasks that run for 5ms and switched. These were the processes and algorithms were followed in the OS. In our project the temperature is maintained for certain level by temperature sensor (LM35) if it reaches above the level we switch on the fan. PIR sensor will sense the live human it will switch on the light. For the emergency case alarm were on by pressing the emergency button, the different temperature were maintained by different sensor and are processed to the output with the help of the OSA RTOS.- Design of Bio Signal Sensors and Signal Conditioning Circuits

This paper describes a design and development of a method that acquires eyeball and eye blink signals .Then the acquired signals are used in controlling assistive/interfaced devices to help subjects who are partially paralyzed patients. Thus the application lies in the fact that the model developed is not limited to the degree of paralysis which has occurred. The design developed is checked for its validity and is found to be 90% accurate. The experimentation was done on partially paralyzed subjects as their eyeball movement and the eye blink were found to be normal. These eye movements and brainwave signal acquisition of data can be used to control a number of interactive devices such as a robot, a GUI or the movement of wheel chair.

Many physiological disorders such as Amyotrophic Lateral Sclerosis (ALS) or injuries such as high-level spinal cord injury can disrupt the communication path between the brain and the body. People with severe motor disabilities may lose all voluntary muscle control. The disabled people with the above mentioned problems are forced to accept a reduced quality of life which may result in dependence on caretakers. To deal with these problems, sophisticated design of equipments for data acquisition and signal processing of bio potentials are required. An interface which communicates between a man and machine can solve this problem to a great extent. The proposed research presents an advanced man-machine interface by designing sensors that acquire EEG, EOG and EMG signals from brain, eyes and muscles respectively.This paper describes a design and development of a method that acquires eyeball and eye blink signals .Then the acquired signals are used in controlling assistive/interfaced devices to help subjects who are partially paralyzed patients.

In this work a new approach of multi response optimization for turning process in Inconel 718 using Taguchi based desirability function analysis (TDFA) is presented. Experiments based on Taguchi L9 orthogonal array (OA) was considered in this study. Three machining parameters viz., cutting speed (v), feed rate (f) and depth of cut (d) are optimized by multi response considerations namely surface roughness (Ra), tool wear (VB), tool life (TL), cutting force (F), cutting power (P) and material removal rate (MRR). The approach obtains composite desirability value for the multiple response using individual desirability values evaluated. The optimum parameters are obtained based on composite desirability value. It is observed that the combination of turning parameters as v = 35 m/min, f = 0.1 mm/rev and d = 1.25 mm (i.e., v2-f1-d2) are obtained as optimal parameters producing Ra, VB, TL, F, P, and MRR respectively as 0.46128 μm, 0.1140 mm, 21.8296 min, 770.135 N, 4.89497 kW, 4375 mm3/min. Confirmation test of the predicted result shows the maximum % error is 6.67.

Metal matrix composites (MMCs) having aluminum (Al) in the matrix phase and particulates/particles of silicon carbide (SiCp) in reinforcement phase have been found in common use for making components in manufacturing industries with various operations viz., turning, milling, grinding, and drilling as well as number of non conventional machining processes. Recently the machinability study of composite machining has attracted researchers. Surface roughness (Ra) and tool flank wear (VB) are two important parameters are studied. Researchers’ employed numbers of conventional and soft computing based computational techniques for modelling and optimization machining process with are single/multiple optimization objective. In the present work, an attempt has been made to obtain optimum process parameters in turning Al/SiCp using carbide tool using Taguchi grey relational analysis. Cutting speed (v), feed rate (f) and depth of cut (d) are three machining parameters on which Ra and VB depends. In the present investigation Taguchi L9 orthogonal array of experimental design were considered and grey relational analysis is used for obtaining optimal parameters of the multi response problem. The predicted result shows that the surface roughness and tool wear at optimum cutting conditions found as 4.08 μm and 0.72mm respectively, resulting the percentage of error as 1.03% for Ra and 5.5% for VB. The method does not require mathematical computation and can be applied easily for multi response problems.Keywords

Assemblies and its actions are derived from the basic mechanical chain mechanisms. These relative motions are most important term to achieve the required function. Precision and accuracy is the sound term of assembly parts for automobile body. Over all efficiency of automobile body function may contributed by even a small element of the assembly parts. Failure of small element in a part may affect function of the body system. Every part of the assembly should meet the basic requirement like strength. There should not be any failure of the product during its entire life time, what reliability engineering talks about. Consideration must be tune to the over all life time function not only at the period of launching. Achieving those strategies can be possible in many ways. Factors to be consider for choosing the right way to meet the requirement which may balance functional constrain and operational conditions. Optimization is term which establishing the balancing of functional constrain and operational condition. This paper deals about the optimization of automobile body part which fails during its function. CAD system made this project simpler to achieve optimized solution for the problem.- Quality Improvement in Automobile Assembly Production Line by Using Kaizen

The 'part mismatch problem' is one of the general quality, problems in automobile assembly production line. Part mismatch affects the production by quality rejection, rework, down time etc. Most of the time part mismatches leads to major functional problem at the assembly section. Kaizen is a method which can control and eliminate such part mismatch problems in automobile assembly production. In this paper, the applicability of kaizen for quality improvement in the production of automobile assemblies with a case study is illustrated. By using kaizen, automobile assembly production line quality problem is solved. Case study about the bracket mismatch leads to brake hose mounting nut offset. This was the major problem of the under body assembly. Step by step kaizen procedure followed to solve the problem by data collection, ischolar_main cause analysis, selection of best solution method, corrective action, documentation and continuing improvement. Kaizen implementation for solving the problem also reflects in the improvement of quality, cost reduction, delivery to customer, morale of the employees and safety. Kaizen was found to be an effective process for improving the quality and productivity. Practical implications of Kaizen can improve the productivity by downtime reduction and quality improvement.- Design off a Pneumatic Circuit for Component Assembly

Pneumatic circuits are designed by various methods. Earlier circuits were designed based on intuitive method which mostly fulfil only the operational requirements. Control aspects and systematic design are evolved by using analytical techniques like Cascade, Karnaugh - Veitch (K-V) diagram, etc., and being used nowadays. In the present investigation, three above methods are analyzed for the component assembly problem. Different features like cost, control aspects, fault diagnosis, etc., are compared and K-V diagram methodology is found more appropriate in many respects, selected for circuit design.- Facility Layout Design in Cellular Manufacturing:An Approach to Minimize Makespan
