Abstract
The steering columns in a steering system are one of the main devices of an automobile. It is a very important part to attain stability and
steady movement of the vehicle. It consists of two yokes, one on each shaft, connected by a cross-shaped intermediate member i.e.
spider. Motion transmission system of vehicles consist several components which sometimes encounter unfortunate failures. Some
common reasons for the failures may be manufacturing and design faults, maintenance faults, raw material faults, material processing
faults as well as the user originated faults. In this paper finite element analysis of the component is carried out to find the stress and
displacement of the final product. For modeling of the component, CATIA V5 R17 software is used. Preprocessing work like meshing
and analysis work is carried out in HYPERWORKS software. Using FEA analysis, we can identify the nature and characteristics of
stresses acting on the yoke and also evaluate the influence of the loads/ mass/ geometry/ boundary conditions over the yoke.

IMPLEMENTATION OF LOSSLESS HYPERSPECTRAL AND MULTISPECTRAL IMAGE COMPRESSION ...AM Publications
A collection of spectral images over several wavelength intervals for the same scene is called a multispectral or hyperspectral image. Hyperspectral imagery consists of much narrower bands (10-20nm). A Hyperspectral image could have hundreds of thousands of bands. Hyperspectral imaging is related to multispectral imaging. In this paper we present a implementation in C using Microsoft visual studio of lossless hyperspectral and multispectral image compression algorithm given by CCSDS. This paper is used to show the effect of parameter settings on the overall performance of the CCSDS standard i.e. number of prediction bands, the local sum type, the prediction mode and the value of Vmax because these parameter values are needed for Hardware implementation. The algorithm is verified by applying AVIRIS data set as input to the system and also reconstructing the image pixel by pixel.
Design and manufacture of an angle adjustable crutch with kennedy key mechanismeSAT Journals
Abstract A crutch is a mobility aid that transfers weight from the legs to the upper body. It has been observed that users of walking aids require double the energy than the normal gait. Users experience a lot of stress at underarm and wrist while using standard underarm or forearm crutches which is the primary reason for pain and various medical complications. Therefore, a new design of crutch has been developed which allows the user to apply his/her weight over a larger area along the forearm instead of wrist and underarm. The primary objective of the study is provide more comfort to the end user of the crutch. The modeling of the new crutch design has been done using CAD modeling package (Catia). Finite Element Analysis (FEA) of the design has been conducted using ANSYS to understand the stress behavior in the new model. The new crutch has been fabricated using aluminum alloy because of its properties like high strength to weight ratio and low density. The fabrication of the new crutch has been performed in such a way that it ensured the entire crutch can be disassembled easily thus making it easily transportable. The testing of the new crutch has been carried out using energy expenditure method to assess the comfort level of the user.

Non linear analysis of Robot Gun Support Structure using Equivalent Dynamic A...IJMER
Robot guns are being increasingly employed in automotive manufacturing to replace
risky jobs and also to increase productivity. Using a single robot for a single operation proves to be
expensive. Hence for cost optimization, multiple guns are mounted on a single robot and multiple
operations are performed. Robot Gun structure is an efficient way in which multiple welds can be done
simultaneously. However mounting several weld guns on a single structure induces a variety of
dynamic loads, especially during movement of the robot arm as it maneuvers to reach the weld
locations. The primary idea employed in this paper, is to model those dynamic loads as equivalent G
force loads in FEA. This approach will be on the conservative side, and will be saving time and
subsequently cost efficient. The approach of the paper is towards creating a standard operating
procedure when it comes to analysis of such structures, with emphasis on deploying various technical
aspects of FEA such as Non Linear Geometry, Multipoint Constraint Contact Algorithm, Multizone
meshing .

A novel dual point clamper for low-rigidity plate milling with deformation co...eSAT Journals
Abstract
The surface profile accuracy plays a significant role in achieving the overall product’s functional performance, which is seriously impacted by the cutting forces, clamping forces, and residual stresses. Conventionally, many researches about deformation compensation focus on cutting forces and fixture layout and do not consider clamping forces. Actually, clamping forces, which would dynamically change along with the movements of cutting tools, are essential in precision machining process. In this paper, a novel dual-point clamper method with adaptive deformation compensation is proposed to improve the workpieces milling precision. Based on the Generalized Principle of Superposition Method, a mathematical model considering the deflection from both cutting forces and clamping forces has been estimated and compared with the traditional clamping scheme. Both 3D finite element model (FEM) based simulation experiments and experimental case studies are carried out, and their results show good agreement with each other. The deflection computation and prediction from numerical studies indicates the efficiency and correctness of the proposed approach.

Comparative study of rc framed structures using spectra based pushover analysiseSAT Journals
Abstract Spectra based multimodal adaptive pushover analysis considers higher modes of vibration and combines them using SRSS rule and scale factors. Damage index for the structures are calculated to evaluate the degree of damage occurred after a seismic event. For the present study the Spectra based multimodal adaptive pushover analysis is adopted for G+ 4 storeys Symmetric and G+ 4 storeys Asymmetric Reinforced concrete framed structures. The Expended Energy based damage index methods are used to calculate Damage Index for symmetric and asymmetric structures. ETABS 2015 software is utilized for modeling and analysis of Reinforced concrete framed structures. The comparative studies are carried out between the structure considering only 1st mode and considering all modes and compared between 3 methods of damage index. It is observed that the capacity obtained by considering all modes is less than the capacity obtained by considering only 1st mode. The target displacement obtained considering only 1st mode is less than the target displacement obtained considering all modes. And the damage index obtained by considering all modes is more than the damage index obtained by considering only 1st mode. Therefore it is necessary to consider all modes to get accurate results. In asymmetric building the ductility is less, the capacity is less, demand is high, and degree of damage is more when compared with symmetric building.

Abstract An intent of this project is to reduce the weight of one way clutch which is being used in automotive transmission enabled sports cars. By reducing the weight we can achieve better efficiency in terms of strength and also to increase the transmission power from torque converter wherein which engaging and disengaging happens. One way roller clutch is one, when the unit rotates in one direction the rollers slip or free-wheel, but when a torque is applied in the opposite direction, the rollers lock between outer cage (cam) and inner cage, producing a wedging action and binding because of friction. The rollers are spring-loaded. Design parameters like maximum torsional deflection, minimum hoop`s stress are considered for to get increased efficiency. In order to achieve this FEA analysis and optimization technique is carried here. Optimization is the mathematical discipline which is concerned with finding the maxima and minima of functions, possibly subject to constraints. Here optimization is carried out by using the global parameters optimization technique. Keywords: FEA analysis, Global parameters, Minimum hoop`s stress, Weight
Design and analysis of fixture for a stone crusher bodyeSAT Journals
Abstract This paper deals with the design and analysis of the welding fixture for the body of a stone crusher. A fixture is a work-holding or support device used in the manufacturing industry. Fixtures are used to securely locate (position in a specific location or orientation) and support the work, ensuring that all parts produced using the fixture will maintain conformity and interchange ability. Locating and supporting areas must usually be large and very sturdy in order to accommodate welding operations; strong clamps are also a requirement. The toggle clamps are generally used. The body of a stone crusher consists of various plates that have to be welded to each other with a specified tolerance and weld quality. The material used in the manufacture of different parts of body of a stone crusher is Mild steel which is one of the most commonly used materials in the field of fabrication. All the welding processes are carried out by CO2 welding to ensure the quality of weld is as per the requirement. We have modeled a weld fixture by using UNIGRAPHICS NX8.0 software which is one of the software used for modeling components in most of the design based industries. While the modeling of the components the material selection is carried out simultaneously based on the design considerations related to loads, etc. Later the stress concentration and deformation on the baseplate of the weld fixture have been found by applying certain load on the baseplate, using the Finite Element Analysis (FEA) by using ANSYS software that provides best output within few seconds. Finally the stress concentration and deformation results are presented in this document. Key Words: welding fixture, stone crusher body, toggle clamp, modeling, Finite Element Analysis.

Review: Composite Flywheel for High Speed ApplicationAM Publications
Flywheel is a device to smoothen the cyclic fluctuation of speed change when delivering constant output
power from the engine. It has no influence on the mean speed of the prime mover. It has no influence on the varying
load demand on the prime mover or the delivered power from the prime mover. In the forgoing discussion, it is
observed that turning moment diagrams for the cycle show period during which torque is in excess of the mean torque
responsible for the constant power output and also periods during which the torque is less than the mean torque. Thus
the speed of the flywheel would increase during period of excess of torque during the cycle and the speed will fall
during the period of the deficit torque during the cycle. Thus a flywheel stores energy and releases energy during the
cycle without affecting mean energy output. Thus a properly designed flywheel has to ensure the cyclic fluctuations of
speed within prescribed limits preferably as small as possible. The main objective of our project is to reduce weight of
automobile by using composite material. In this Project Work taking Flywheel as an Automobile component and
applying FEA analysis using ANSYS to optimize weight and strength of flywheel. Here Performing Analysis on metal
flywheel, carbon fiber flywheel and composite i.e. metal and carbon fiber flywheel. By using ANSYS stresses obtained
& compared with analytical calculations, also weight is compared. Composite flywheel made from steel rim & carbon
fiber body will be safe for automobile applications like F1 car. From analysis & analytical results composite flywheel
for automobile can be selected.

A helicopter main rotor or rotor system is the combination of a rotary wing and a control system that generates the aerodynamic lift force that supports the weight of the helicopter, and the thrust that counteracts aerodynamic drag in forward flight. In the field of rotorcraft, the research in this project is currently focusing on active blade systems to adapt the aerodynamic properties of the blade to the local aerodynamic conditions. Fuel-efficiency, reduction of vibration and noise and increase of the helicopter maximum speed are the benefits expected from these new technologies. A helicopter's rotor is generally made of two or more rotor blades. Rotor blades are made out of various materials, including aluminum, composite structure, and steel or titanium, with abrasion shields along the leading edge. The blade pitch is typically controlled by a swash plate connected to the helicopter flight controls. An Active Twist Rotor (ATR) is developed for future implementation of the individual blade control for vibration and noise reduction in helicopters. The rotor blade is integrally twisted by direct strain actuation using active fiber composites (AFC). In this thesis, the model of rotor blade is designed and analyzed. 3D models are done in CATIA. Analysis is done in Ansys. The materials used for original model are steel and Aluminum alloy, The modified model is analyzed by specifying aluminum alloy using solid element and also the shell element. The optimization results have been obtained for design solutions, connected with the application of active materials.

Comparative studies on formability analysis in metal formingeSAT Journals
Abstract Sheet metal products are one of the most important semi-finished products used in the steel industry, and metal forming technology is therefore an important engineering domain. The development of new sheet metal forming processes, tooling and so on, has until now, to a large extent been based on experience, rules of thumb and trial- error experiments without or with only little use of scientifically based engineering methods. As mentioned above, experience is not enough, and trial-error experiments are expensive with regard to both money and time. The forming limit diagram (FLD) shows metal formability in metal forming with less cost. . The forming limit diagram typically represents the maximum permissible range of major and minor strains that a typical sheet material can undertake without failure. The forming limit diagram is experimentally measured for each sheet material by placing a grid of circle on the sheet sample and then deforming the same. A comparison of the original and the extensions in the marked grids on the sheet sample provide an estimate of the major and minor strain of the sample. This paper presents a case study of automotive component spring seat. By placing the grid of circles on the component and by measuring the dimensions of deformed circles a forming limit diagram has drawn. The simulations were carried out by fast form advanced software. The results achieved concluded that, safe forming zone is of bottom part and wrinkling tendency is present on side wall of component.

Design evaluation and optimization of steering yoke of an automobileeSAT Journals
Abstract The purpose of a steering system is to control the direction of the vehicle by operating the steering wheel of the steering system. The steering columns in a steering system are one of the main devices of an automobile. It is a very important part to attain stability and steady movement of the vehicle. The steering yoke consists of two forged-steel yokes or forks joined to the two shafts being coupled and situated at right angles to each other. A spider hinges these two yokes together. Since the arms of the spider are at right angles the spider arm rocks backwards and forward between four extreme positions. Motion transmission system of vehicles consist several components which sometimes encounter unfortunate failures. Some common reasons for the failures may be manufacturing, design faults, maintenance faults, raw material faults, material processing faults as well as the user originated faults. In this paper structural optimization of the steering yoke is carried out. For modeling of the component, CATIA V5 R17 software is used. It has been found that there are essentially in two stages of the design process that structural optimization can be applied. In the early stage of concept generation, topology optimization should be used to develop an efficient structure from the beginning. At this level an automatized variation of optimization parameters was proven useful to and the best feasible design possible. In the later stage, shape and size optimization should be used to fine-tune the structure realized from the topology optimization and carried out physical experimentation to validate the model. Keywords: Steering Yoke, Structural optimization, CATIA V5, Hyperworks

PEDESTRIAN DETECTION IN LOW RESOLUTION VIDEOS USING A MULTI-FRAME HOG-BASED D...AM Publications
Detecting pedestrians in low resolution videos is a challenging task, due to the small size of pedestrians in the images and the limited information. In practical outdoor surveillance scenarios the pedestrian size is usually small. Existing state-of-the-art pedestrian detection methods that use histogram of oriented gradient (HOG) features have poor performance in this problem domain. To compensate for the lack of information in a single frame, we propose a novel detection method that recognizes pedestrians in a short sequence of frames. Namely, we take the single-frame HOG-based detector and extend it to multiple frames. Our detector is applied to regions containing potential moving objects. In the case of video taken from a moving camera on an aerial platform, video stabilization is first performed to register the frames. A classifier is then applied to features extracted from spatio-temporal volumes surrounding the potential moving objects. On challenging stationary and aerial video datasets, our detection accuracy outperforms several state-of-the-art algorithms.

EFFECT OF SILICON - RUBBER (SR) SHEETS AS AN ALTERNATIVE FILTER ON HIGH AND L...AM Publications
A digital radiography delivers a radiation dose to patients; therefore it poses potential risk to the patients. One effort to reduce dose is carried out using a radiation filter, e.g. Silicone Rubber (SR) sheet. The purpose of this research was to determine the impact of the SR sheet on the high contrast objects (HCO) and the low contrast objects (LCO). The dose reduction was determined from attenuation x-rays before and after using the SR sheet. Assessment of HCO and LCO was observed from CDR TOR phantom at tube voltage of 48 kVp and tube current of 8 mAs. The physical parameter to assess image quality was the Signal to Noise Ratio (SNR) value in LCO. The maximum x-ray attenuation using the SR sheet is 48.82%. The visibility of the HCO remains the same, namely 16 objects; however the LCO slighly decreases from 14 objects to 13 objects after using the SR sheet. The SNR value decreases with an average value of 15.17%.Therefore, the SR sheet as a alternative filter has no effect on the HCO and has realtively little effect on the LCO. Thus, the SR sheet potentially is used for radiation protection in patients, especially on examinations that do not require low contrast resolution.

Cloud computing means storing and accessing data and programs over the Internet instead of your computer's hard drive. The cloud is just a metaphor for the Internet. The elements involved in cloud computing are clients, data center and distributed server. One of the main problems in cloud computing is load balancing. Balancing the load means to distribute the workload among several nodes evenly so that no single node will be overloaded. Load can be of any type that is it can be CPU load, memory capacity or network load. In this paper we presented an architecture of load balancing and algorithm which will further improve the load balancing problem by minimizing the response time. In this paper, we have proposed the enhanced version of existing regulated load balancing approach for cloud computing by comping the Randomization and greedy load balancing algorithm. To check the performance of proposed approach, we have used the cloud analyst simulator (Cloud Analyst). Through simulation analysis, it has been found that proposed improved version of regulated load balancing approach has shown better performance in terms of cost, response time and data processing time.

NUMERICAL SIMULATIONS OF HEAT AND MASS TRANSFER IN CONDENSING HEAT EXCHANGERS...ssuser7dcef0
Power plants release a large amount of water vapor into the
atmosphere through the stack. The flue gas can be a potential
source for obtaining much needed cooling water for a power
plant. If a power plant could recover and reuse a portion of this
moisture, it could reduce its total cooling water intake
requirement. One of the most practical way to recover water
from flue gas is to use a condensing heat exchanger. The power
plant could also recover latent heat due to condensation as well
as sensible heat due to lowering the flue gas exit temperature.
Additionally, harmful acids released from the stack can be
reduced in a condensing heat exchanger by acid condensation. reduced in a condensing heat exchanger by acid condensation.
Condensation of vapors in flue gas is a complicated
phenomenon since heat and mass transfer of water vapor and
various acids simultaneously occur in the presence of noncondensable
gases such as nitrogen and oxygen. Design of a
condenser depends on the knowledge and understanding of the
heat and mass transfer processes. A computer program for
numerical simulations of water (H2O) and sulfuric acid (H2SO4)
condensation in a flue gas condensing heat exchanger was
developed using MATLAB. Governing equations based on
mass and energy balances for the system were derived to
predict variables such as flue gas exit temperature, cooling
water outlet temperature, mole fraction and condensation rates
of water and sulfuric acid vapors. The equations were solved
using an iterative solution technique with calculations of heat
and mass transfer coefficients and physical properties.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
