ABSTRACT: The role of robotics in society is no longer restricted to assembly and manufacturing. Robots are finding their way into -a wide spectrum of tasks that directly link human and machine. Due to the modelling error or environmental uncertainties, robot motion may present a significant positioning error by using a conventional Computer-Torque Method. To improve tracking capability of robot manipulators, sliding mode control and nonlinear control algorithms have been introduced, but computation is costly, and thus a fast motion execution using simple computer sources is impossible. To resolve this problem, the resolution and position accuracy of magnetically suspended frictionless Hexapod multi DOF manipulator is designed and it will simulate with the help of Adams Software. From Reverse Position Analysis the system joint information can be obtained for a specified operational position. Forward kinematics for a manipulator is the process to calculate the position (or motion) of an end effectors when joint variables are specified. The process is carried out by multiplying sequentially the 4x 4 homogeneous transformation matrix of each joint and finding the transformation matrix Ti for the corresponding position The main objective of this Project is to Study the kinematic behavior of the Multi DOF Manipulator mechanism and to control the overall action and to develop a procedure for the optimal design of a redundantly actuated Multi DOF manipulator and to determine the geometric parameters and operating limits.

Abstract: This paper introduces the use of the voltage multiplier technique and passive absorption circuit applied to the non-isolated dc-dc converter in order to obtain high efficiency and high voltage gain. A passive absorption circuit is inserted in the interleaved flyback converter to transfer the leakage energy to load. The operation principle of the circuit is explained. This paper also deals with MPPT controlled high step up dc-dc converter. The switching element used in the flyback converter is MOSFETs, which is completely on and completely off. This is because MOSFET has high power rating and high switching speed. Moreover, high voltage conversion ratio is achieved. The simulated results are presented with R load.

ABSTRACT: This study was conducted to assess cattle husbandry practices in the crop-livestock production system areas of the highland and mid-altitude and pastoralists in the lowlands of Burji woreda of Segen Zurea zone of southern Ethiopia. The cattle husbandry practices were assessed based on one time field visit, questionnaire survey and focus group discussions in highland, mid-altitude and lowland altitude. A total of 100 farmers were selected randomly from 10 peasant associations, which are selected based on proportion of peasant associations exist in each altitude zones of peasant association. The survey showed that the majorities 81% of household heads under investigation were males and the rest 19% were female. The average family size in the highlands, mid-altitudes and pastoral areas were 9.0±0.5, 9.4±0.3 and 11.1±0.5 respectively. Average livestock holding per household varied across the altitude zones, especially cattle and oxen holding per household in highland, midland and lowland altitude zones were, 13.7±2 cattle and 4.1±0.4 oxen, 11.6±1 cattle and 3.98±0.3 oxen and 29.3±2.5 cattle and 6.2±0.4 oxen respectively. Natural pasture is the major feed resource of the woreda, but communal grazing land in their area is dwindling at an alarming rate. Crop residues provided the second major feed resources for livestock, particularly during the dry season when biomass of natural grazing lands is very low. The constraints to cattle production system were feed shortage, drought, and diseases and parasites particularly Trypanosomiasis, shortage of grazing land, veterinary services, extension services, marketing and other infrastructures. Hence, more emphasis should be given to improving livestock productivity through strong extension services in proper management of the rangelands, feed conservation, crop residues treatment, healthcare and provision of credit facility.

Abstract: Mobile ad hoc network (MANET), flexible and self-autonomous wireless network architecture, is very promising to find many important applications in the daily information exchange, disaster relief, military troop communication, etc. In MANETS for long life and reliability the throughput capacity must be increased. This work deals the per node throughput capacity of a MANET, where the transmission power of each node can be controlled to adapt to a specified transmission range and a generalized two-hop relay with limited packet redundancy f is used for packet routing. Based on the concept of automatic feedback control and the Markov chain model, an Inter-MANET Routing protocol called InterMR that can handle the heterogeneity and dynamics of MANETs is used. First it defines an Inter-MANET address scheme based on a variety of node attributes .Next the contribution is to provide a seamless routing mechanism across heterogeneous MANETs without modifying the internal routing mechanisms in each MANET, by packet-level simulation, that the performance of InterMR will be improved by adaptive gateway assignment functionalities. From the routing values the throughput parameters is obtained. Increasing the transmission power of the nodes with this routing mechanism improves the capacity, and even at high packet rate increased throughput can be achieved.

Abstract: Media access control is an essential part of wireless communication. To achieve higher communication throughput multi-channel MAC has been studied. Adhoc wireless network's performance is always measured corresponding to the power consumption of the nodes. The overall network connectivity depends on the energy of the nodes. Researchers have proposed many energy efficient MAC protocols to resolve this problem. Altruistic protocol uses the concept of distributed information sharing to reduce power consumption and at the same time improve the throughput. Distributed Information Sharing(DISH) is a new cooperative approach to design multi-channel MAC protocols. It aids nodes in their decision making process by sharing information through neighboring nodes. It share control information with each other so that nodes can make decisions during communication. In a multi-channel network, DISH avoids collisions by notification from neighboring nodes about channel conflict and deaf terminal problem. Energy efficient strategy altruistic DISH is used. It uses multi-hop communication. Data retransmission is avoided with the assist of intelligent node. Priority is given to the nodes if it chooses the busy receiver. Altruistic protocol is compared with In-situ DISH, and find that altruistic protocol significantly outperforms. It conserves energy without compromising the throughput performance. Through simulations it shows that altruistic protocol conserves better energy compared to other. The experimental results confirm the viability of altruistic protocol and the idea of DISH. Hence by using DISH energy efficiency for cooperative multi-channel MAC is achieved.

ABSTRACT: There has been little information in regard to agricultural drought prediction. This paper aimed at coming up with an efficient and intelligent agricultural drought prediction system. By using a case study approach and knowledge discovery data mining process this study was preceded by drought literature review, followed by analysis of daily 1978-2008 meteorological and annual 1976-2006 maize produce data both from Voi Taita-Taveta (Coast Province in Kenya). The design and implementation of an agricultural drought prediction system, was made possible by computer science programming for meteorological data preprocessing, classification algorithms for training and testing as well as prediction and post processing of predictions to various agricultural drought aspects. The study was evaluated by comparison of predicted with actual 2009 data as well as the Kenya Meteorological Department (KMD) 2009 records. The evaluation of this study results indicated consistency with the KMD 2009 outlook. The results showed that the application of classification algorithms on past meteorological data can lead to accurate predictions of future agricultural drought. The recommendation is that future work can be based on designing a solution for multiple regions with multiple crops.

ABSTRACT: Software estimation accuracy is one of the greatest challenges for software developers. Software cost and time estimation supports the planning and tracking of software projects. The present paper is directed to design a model which should be accurate and comprehensible in order to inspire confidence in a business setting. Software effort estimation models which adopt a neural network technique provide a solution to improve the accuracy. However, no univocal conclusion to which technique is the most suited has been reached. This study addresses this issue by reporting on the results of a large scale benchmarking study. Different types of techniques are under consideration including techniques such as Multilayered Perceptron Network, Radial Basis Function Neural Network, Support Vector Machines, Extreme Learning Machines and Particle Swarp Optimization. Studies are made using COCOMO II data. Results are provided for MMRE and PRED (25) accuracy measures.

ABSTRACT: The STBC will improve the performance which is degraded by increase in data rate. Our work will shows the probability of error decreases with the increase of SNR. The coding gain measures the distance between the descending probability of error curve from the ordinate axis and is an indication of how high the SNR is before the probability of error curve starts to fall. Our work shows that orthogonal code performs better than the Alamouti code. Simulation results show that full transmission rate is more important at very low SNR values and high BERs, whereas full diversity is the right choice for high SNR values and low BERs. Our work done on diversity analysis of multiple-input multiple-output (MIMO) space-time block codes using various receiving techniques in a Rayleigh fading channel, Performance analysis of different space-time block codes using M-ary phase shift keying (PSK) in a Rayleigh fading channel and Performance analysis of joint transmit and receive antenna selection in a STBC coded MIMO system by comparing sphere decoder technique with zero-forcing (ZF), minimum mean square error (MMSE) and maximum likelihood (ML) techniquesThe performance of the proposed OSTBC over frequency-selective fading channels we compare with other existing methods for MIMO-OFDM systems.

ABSTRACT: There has been a considerable imbalance between the availability of conventional building materials and their demand in the recent past. On the other hand the laterite quarry waste is abundantly available and the disposal of waste plastics (PET, PP,etc.) is a biggest challenge, as repeated recycling of PET bottles pose a potential danger of being transformed to a carcinogenic material and only a small proportion of PET bottles are being recycled. In this work an attempt has been made to manufacture the bricks by using waste plastics in range of 60 to 80% by weight of laterite quarry waste and 60/70 grade bitumen was added in range of 2 to 5% by weight of soil in molten form and this bitumen- plastic resin was mixed with laterite quarry waste to manufacture the bricks. The bricks manufactured possess the properties such as neat and even finishing, with negligible water absorption and satisfactory compressive strength in comparison with laterite stone to satisfy the increasing demand of conventional building materials.

ABSTRACT: The increasing demand for battery-powered and green-compliant applications has made power management a dominant factor in SoC design. Clock power contributes 40% of total chip power.To get maximum reduction in power an algorithm has been proposed in which single-bit flip-flops are replaced with maximum possible Multi-Bit Flip-Flop (MBFF) without affecting the performance of the original circuit. Firstly mergable flip-flops are identified based on synchronous clocking and replaced without affecting the performance however replacement will change the location of flip-flops leading to timing and capacity constraint. Tanner EDA V13.0 has been used which reduces the power by 15%.

ABSTRACT: In classification, discrimination is a type of treatment that includes denying the membership in one group opportunities that are available in another group. Discrimination based on age, religion, gender, caste, disability, employment, language, race and nationality. In this technique, direct and indirect discrimination is prevented using rule protection and rule generalization methods and BIRCH (Balanced Iterative Reducing and Clustering using Hierarchies) is used to perform hierarchical clustering for huge data-sets. To enhance privacy, we propose a virtual password concept to secure user's passwords in banking process. We applied user-determined randomized linear generation functions to secure user's passwords based on the fact that a server has more information than any adversary does. We are evaluating metrics for proposed methods that impact on information loss and data quality in data mining.

ABSTRACT: In this paper, electric vehicle technology which is recharged in the combination of multi sources (when it is plugged in to a power source from the grid and also from renewable energies like solar). However the solar radiation never remains constant. It keeps on varying throughout the day. The need of the hour is to deliver a constant voltage to the grid irrespective of the variation in temperatures and solar insolation. We have designed a circuit such that it delivers constant and stepped up dc voltage to the load. At various insolation levels, the load is varied and the corresponding variation in the input voltage and current to the buck-boost converter is corrected and noted. These electric vehicles help to keep the environment clean by reducing the amount of toxins emitted from standard exhaust systems and lower operating cost than the conventional internal combustion engine based vehicle. The main objective of this project is used to improve battery performance/efficiency as well as life together using converter and also monitoring the system using PIC16F877A. The effectiveness of the system is verified through the simulations using Simulink/ MATLAB (R2013a) package.
