PERFORMANCE EVALUATION OF MAGNETO RHEOLOGICAL DAMPER FOR VEHICLE SUSPENSION WITH SEMI ACTIVE CONTROL SYSTEM -A REVIEW
No full textThevehicle suspension is used to minimize the vibration transferring from the irregularroad surfaces. The control of these vibrations is still to be the boomingfield for the researchers. The increasing demand of ride reliefand road stability leads to the development of suspension systems with new control strategies and actuating devices which can provide the strongperformance. Hence to achieve this semi active control system is adapted to overcome the limitation of active as well as passive suspension system. Semi active control is well known for its low implementation cost, simplicity in construction and lower power consumption than active control. The actuation devices mostly used for semi active control are piezoelectricdampers, magneto rheological damper, tuned liquid column damperand electro rheological damper, out of whichthe MR damper has a semi active control and it had been acceptedover last several years. MR fluids consist of the oil with iron particles in it. The device forces are adjusted by varying the strength of magnetic field
AUTOMOMOTIVE NOISE AND VIBRATION CONTROL
No full textThe study of sound, noiseand vibration is an emerging and interesting topic in the present era. The study on NVH has resolved lot many problems in society with respect to noise. From last few decades literature reviews that many works are done on exterior design of automotive than interior design. The reduction of noise because of vibration of parts of the body of a vehicle is a challenging task. In this paper the properties of sound, noise and vibrations are reviewed. The controlling techniques of noise and vibrations are elaborated. The properties of sound absorbing materials are explained. Finally the applications of materials for noise reduction and measuring instruments are listed
MODIFIED CONVOLUTIONAL NEURAL NETWORK FOR ARIARY BANKNOTES AUTHENTICATION
No full textThis paper presents a new algorithm named modified convolutional neural network (MCNN) to authenticate current existing banknotes in Madagascar. At the end of processing, we are able to identify the money face value and fake notes according to the input. Convolutional neural network (CNN) is the promising technical to solve such problem although feature extraction layer takes time due of convolution and spooling operations. The solution that we propose here is to swap this layer with pulse coupled neural network (PCNN) which has a capability to collect easily input image characteristics before going through fully connected layer. So, we have three images as input because one banknote has recto, verso and watermarked faces which are converted to gray. Our pulse couple neural network extracts all features to form a single vector called image signature. This vector is presented to full connected neural network constituted by few hidden layers, one output layer using softmax function as neural activation function. It means that we have authentic’ s probability
SIMULATION MODELING
No full textSimulation solves real world problems safely and intelligently. It is a convenient analysis tool: it is visual, easy to understand and easy to check. In various areas of business and science, simulation helps to find optimal solutions and gives a clear understanding of complex systems. Bits Instead of Atoms: Simulation is an experiment to faithfully digitalize any system. Unlike physical modeling, such as creating a layout for a building, simulation is based on computer technology using algorithms and equations. The simulation model can be analyzed over time, and the animation can be viewed in 2D or 3
DESIGN AND ANALYSIS OF NEW COUPLING SYSTEM IN INJECTION MOLDING MACHINE TO IMPROVE SCREW LIFE
No full textInjection molding machine is the most commonly used manufacturing process for the fabrication of plastic parts. The plastic being melted in injection molding machine and then injected into the mould. The barrel contains reciprocating screw for injecting the material into the mould and the material is also melted into the barrel. This project deals with, the solution of problem occurred for reciprocating screw of Injection molding machine. It identifies and solves the problem by using the modeling and analysis techniques
ENERGY COMPETENCE ROUTING PROTOCOL IN UTILIZING AODV IN MANETS
No full textIn MANETs each hub can go about as the portal. In this exploration concentrate is laid on vitality productivity. There are many directing conventions in MANETs like DSDV, DSR and AODV and so forth and everyonehas its own particular approach for dispersal of information bundles in MANETs. In any case, these directing conventions are less vitality proficient. The point of this exploration is to outline a steering convention which would be superior to the currentones regarding vitality usage and conveyance proportion. In this examination a vitality productive AODV steering convention in which Dijkstra calculation is upgraded to enhance the general execution of the system. Existing frameworks are not fit for finding the most limited and vitality based way among the hubs in the system if various hubs bomb all the while. Execution parameters are Packet conveyance proportion, Throughput, Energy utilization and directing overhead. The reproduction is finished utilizingsystem test system NS-2
SPEECH COMPRESSION TECHNIQUES: A REVIEW
No full textSpeech is the vocalizer form of human communication,and based upon the syntactic combination of lexical and vocabularies. The aim of speech coding is to compress the speech signal to the highest possible compression ratio but maintaining user acceptability.There are many methods for speech compression like Linear Predictive coding (LPC) , Code Excited Linear Predictive coding (CELP) ,Sub-band coding ,Transform coding :- Fast Fourier Transform (FFT) ,Discrete Cosine Transform (DCT) , Continuous Wavelet Transform (CWT) , Discrete Wavelet Transform (DWT) ,Variance Fractal Compression (VFC) , Discrete Cosine Transform (DCT),Psychoacoustics andetc. Few of them are discus in this paper
DESIGN OF DISC TYPE OIL SEPERATOR
No full textThis paper dealswith the separation of oil and water to find out the better solution for oil recovery from the water surface mistureEmpressoil spillto produce oil free water. Also a deal with the fabrication of mechanical equipment to separate oil from the water. Oil and water separator is mechanical equipment, which is used in the environment pollution control from oil spillage. Oil separator helps in removing the oily from the mixingsurface leaked water. By removing the oil from industry misturewater, it becomes free of oil pollution. This is mainly due to acrylic material used in the oil separator. This oil separator can be used in the effluent treatment plant
