Design and Comparative Analysis of Connecting Rod Using Composite Materials []


The connecting rod is the intermediate member between the piston and the Crankshaft. It’s primary function is to transmit the push and pull from the piston pin to the crank pin, thus converting the reciprocating motion of the piston into rotary motion of the crank. This thesis describes designing and Analysis of connecting rod using composite materials. In this, drawing is drafted from the calculations. A parametric model of Connecting rod is modeled using CATIA V5 R21 software. Analysis is carried out by using ANSYS Workbench 14.5 Software. Finite element analysis of connecting rod is done by considering the materials i.e, Titanium Ti-6Al-4V, Aluminum reinforced with Carbon nano tubes Al-MWCNT, E Glass Epoxy, Carbon steel. Analysis is carried out for the two different loading conditions i.e. first load is applied to big end(crank end) and in for second load is applied to small end(piston end) while the respective ends are held fixed. The best combination of parameters like Stress, deformation, weight reduction for Suzuki 150 cc of two wheeler were done using Static and dynamic analysis ( Modal, Harmonic Response, Random Vibration, Response Spectrum Transient Structural, ) Linear Buckling Analysis in ANSYS software. Compared to Ti-6Al-4v, E Glass and Carbon steel Al-MWCNT has more factor of safety, reduced weight, reduction in stress, and its cost also lesser in comparison.


An Enhanced And Secured Video Steganographic System Using Hamming Code []


Due to rapid increase of exchange of large data with technological advancements, video steganography is becoming the better solution for offering greater security for large data. In this paper, an enhanced and secured video steganography algorithm is proposed. Hamming code encoding technique and embedding process in DWT domain are the main key concepts used for the project. At embedding phase, initially secret message is secured by encrypting using a key. Then the secret message is encoded using Hamming code. To ensure furthermore security, secret message is XORed with the random value generated by a private key. The processed secret message is then embedded into middle and high frequency DWT coefficients of selected frames of video. For extraction, reverse process takes place. However, for extracting the secret message, keys should be known. This additional feature of using keys makes the technique more robust. The performance parameters like Peak Signal to Noise Ratio (PSNR) and Mean Square Error (MSE) are calculated to determine the quality of stego video. The obtained results have shown that the proposed algorithm for steganography is highly secured with good perceptual invisibility.


Investigation on WIG(Adv. Marine) Craft Aerodynamic Characteristics []


The paper is about the aerodynamic characteristics of the wing-in-ground effect (WIG) craft model that has a noble configuration of a compound wing was experimentally and Theoretical investigated and wind tunnel(TLE-06) with and without endplates. Lift and drag forces, pitching moment coefficients, and the center of pressure were measured with respect to the ground clearance and the wing angle of attack. The ground effect and the existence of the endplates increase the wing lift-to-drag ratio at low ground clearance. The results of this research work show new proposed design of the WIG craft with compound wing and endplates, which can clearly increase the aerodynamic efficiency without compromising the longitudinal stability. The additional lift provided by the ground effect reduces demand on the engines of an aircraft and power needed in order to stay airborne, thus making it more efficient. The knowledge that ground effect flight is more efficient than traditional flight has lead people to develop craft that exploit this benefit by being designed to fly close to the ground. Development of WIG craft spans roughly over the past 60 years, ranging from small scale recreational craft, to large scale military craft, yet such craft have not become successful mainstream products. This is largely due to the limitations present in existing WIG craft designs, such as the high maintenance nature of having exposed engines in close proximity to the sea, which reduces reliability. Such factors have previously lead to a withdrawal of military funding for research and development in this area, across all major countries that were once rigorously involved in this research. Despite this, the potential still exists for WIG craft design to achieve the functionality required to become successful in niche areas such as high speed transport rather than warfare. And, the use of WIG craft is representing an ambitious technology that will help in reducing time, effort, and money of the conventional marine transportation in the future.


AN EFFICIENT WSN BASED ENERGY HARVESTING SYSTEM USING EMBEDDED SYSTEM []


ABSTRACT: This paper presents a case study of a wireless sensor network (WSN) to support energy management utilizing Web services and middleware technologies. The approach presented proposes the integration of WSNs with Ethernet/Internet/XML/Web Service communications into a „knowledge and information services‟ platform to support energy management which can be accessed via a Web service to support inhabitant actions to reduce energy demand. It is based on the idea of collecting energy information using various wireless devices operating with different communication standards. This is important as there are various communication standards developed for WSNs including ZigBee, 6LoWPAN, Wi-Fi, WirelessHART and ISA100.11a. The hardware components which are needed for a system using one specific communication standard cannot be used directly within another system, due to differences in firmware, radio components, communication standards, and in some cases profile parameters. This is problematic because the components of different systems cannot be mixed and used in combination in order to take advantage of the most useful aspects of products from multiple vendors. The concept and initial testing of the WSN presented in this paper goes beyond current approaches as it uses various wireless devices operating with different communication standards, which can support Web based services for building managers, owners and inhabitants.

Analysis of Efficient CRC Implementation Configurations []


Abstract-A cyclic redundancy check (CRC) is an error-detecting code commonly used in digital networks and storage devices to detect accidental changes to raw data. Blocks of data entering these systems get a short check value attached, based on the remainder of a polynomial division of their contents; on retrieval the calculation is repeated, and corrective action can be taken against presumed data corruption if the check values do not match. Error correction codes provides a mean to detect and correct errors introduced by the transmission channel.

In particular, this project present a set of data encoding schemes operating at flit level and on an end-to-end basis, which allows us to minimize both the switching activity and the coupling switching activity on links of the routing paths traversed by the packets. Further, this concept is enhanced by modifying majority gate with low complex structure. It yields less power consumption in whole encoder process.

POWER CONTROL AND MANAGEMENT WITH INTERLINKING CONVERTER []


ABSTRACT:Hybrid ac/dc micro grids have been planned for the better interconnection of different distributed generation systems (DG) to the power grid, and exploiting the prominent features of both ac and dc micro grids. Connecting these micro grids requires an interlinking ac/dc converter (IC) with a proper power management and control strategy.Nowadays Distribution generation and micro grids are becoming an important line because of their peculiar characteristics. Micro grids are composed of small power sources,which can be renewable, placed near customer sites. Moreover, they have the inherent property of islanding: the disconnection of either the MG from the main grid or a part of a MG from the rest of the MG. This paper proposes the solution for the irreasonability caused by the equivalent sources of PV and wind system by considering the power flow control and management issues amongst multiple renewable energy sources dispersed throughout both ac and dc micro grids by an analysis of local PV-wind hybrid system. This paper facilitates electricity without any fluctuations. This accomplishes a decentralized power sharing method in order to eliminate the need for any communication between DGs or micro grids. This hybrid micro grid architecture allows different ac or dc loads and sources to be flexibly located in order to decrease the required power conversions stages and hence the system cost and efficiency. The performance of the proposed power control strategy is validated for different operating conditions, using simulation studies in the MATLAB software.


ENHANCED DISTRIBUTED PROVABLE DATA POSSESSION IN MULTI-CLOUD STORAGE []


ABSTRACT : Remote data integrity checking is of crucial importance in cloud storage. It can make the clients verify whether their outsourced data is kept intact without downloading the whole data. In some application scenarios, the clients have to store their data on multi-cloud servers. At the same time, the integrity checking protocol must be efficient in order to save the verifier’s cost. From the two points, we propose a novel remote data integrity checking model: ID-DPDP (identity-based distributed provable data possession) in multi-cloud storage. The formal system model and security model are given. Based on the bilinear pairings, a concrete ID-DPDP protocol is designed. The proposed ID-DPDP protocol is provably secure under the hardness assumption of the standard CDH (computational DiffieHellman) problem. In addition to the structural advantage of elimination of certificate management, our ID-DPDP protocol is also efficient and flexible. Based on the client’s authorization, the proposed ID-DPDP protocol can realize private verification, delegated verification and public verification.

REAL TIME TRAFFIC DETECTION BASED OB BACKGROUND SUBTRACTION IN SURVEILLANCE SYSTEM []


ABSTRACT : Abstract - Vehicle detection and classification plays a prominent role in traffic surveillance systems. In the past many methods had been derived and implemented still we find some problems of detection and classification. These problems mainly occur in dynamic texture auch as rain fall, moving trees, mountain and camera configuration. In order to overcome these problems on the vehicles they are some essential traffic parameters, such as vehicle counting,detection and classification. In this paper, to avoid detection and classification problems frame background subtraction has been proposed. Firstly the background method is used to detect the moving objects from the vehicle video. The morphological operation are applied to remove the noise regions and obtaining more accurate segmentation results. After vehicle detection, a object-based vehicle tracking method is used for building the correspondence between vehicles detected at different time instants. After vehicle tracking, we calculate the vehicle count from video. Experimental results are shown better segmention and tracking results compare to Gaussian mixture of model (GMM).


A NOVEL ANALYSIS OF A HYBRID CASCADED MULTILEVEL INVERTER BY FUZZY CONTROLLER BASED ENERGY MANAGEMENT []


ABSTRACT : Battery energy management system in electric vehicles is processed by cascading the batteries the output voltage has to drive the motor by an advanced fuzzy controller. Under state of charge mechanism voltages will differ from the terminal voltages. The stage of cells will be increase in order to maintain the level of charging and discharging cells. For energy management these were connecting to H-Bridge circuit and maintain the voltages and currents with less harmonics even the level of cascaded cells increases by a new FLC. This paper presents a design and simulation of modulation and Fuzzy control strategies are plays main role to minimize THD in Multilevel inverter. These modulation techniques include Sinusoidal Pulse Width Modulation (SPWM). In the proposed topology, each battery cell can be controlled to be connected into the circuit or to be bypassed by a half-bridge converter. All half bridges are cascaded to output a staircase shape dc voltage. Then, the fuzzy based H-bridge converter is used to change the direction of the dc bus voltages to make up ac voltages. The outputs of the converter are multilevel voltages with less harmonics and lower dv/dt, which is helpful to improve the performance of the motor drives. By separate control according to the SOC of each cell, the energy utilization ratio of the batteries can be improved.


A NOVEL AND EFFICIENT METHOD FOR ANTENNA RADIATION PATTERN USING ADAPTIVE FILTERING TECHNIQUES []


ABSTRACT – Smart antenna is recognized as promising technologies for higher user capacity in 3G wireless networks by effectively reducing multipath and co-channel interference. Advent of powerful, low-cost, digital processing components and the development of software-based techniques has made smart antenna systems a practical reality for both base station and mobile station of a cellular communications systems in the next generation. The core of smart antenna is the selection of smart algorithms in adaptive array. Using beam forming algorithms the weight of antenna arrays can be adjusted to form certain amount of adaptive beam to track corresponding users automatically and at the same time to minimize interference arising from other users by introducing nulls in their directions. Thus interferences can be suppressed and the desired signals can be extracted. Here we concentrate on elimination of noise energy in received signals by using variable step size algorithms called NLMS and VSSLMS which are adaptive filtering methods for error reduction. Although we have good performance in operation we extend our work by using LSCMA algorithm for speed convergence in error reduction.
