 Abstract

The design objective is to come up with a mower that is portable, durable, easy to operate and maintain. It also aims to design a self powered mover of electrical source. The heart of the machine is a battery powered dc motor. It comprises of a system of speed multiplication pulleys which drive the cutting blades and the charging unit comprising of 12V alternator and a lift mechanism meant to alter the height of cut.these days we are facing the problems like pollutions, power cut problem etc. In order to overcome these problems, we have thought about the device, which can be performing its functions without causing any of these problems. So we have thought of doing the project on cutting grass, this uses the renewable source of energy for its operation like electric energy. This project aims at developing a portable operated grass cutting device, as there is power shortage. So we have decided to make energy operated device. This will run the DC motor. This motor is connected to blade shaft by the help of screw. This will rotate the blade in high speed, cut the grass. This device will help in building of eco-friendly system

 Abstract

The functioning of brain plays a major role in language acquisition and communication disorders such as Autism and Aphasia may hinder the language skills of a child .The theory of Multiple intelligences by Gardner has great impact on how individuals learn or process information given to them and helps children learn language using the intelligences they possess. Each child with ASD has different sets of intelligences and if these intelligences are utilized in a proper way with different interventions the child can excel in his personal and social life.

 Abstract

Abstract - Region of Interest based compression is an efficient method of compression for images with a particular part to be most significant. It is always a better choice to compress the ROI with lossless compression while the rest of image with lossy compression technique. This paper proposes lossless compression for medical image (ROI) and near lossless compression for the rest of the image. Image other than ROI may contain information that is useful, that is why it is appropriate to use near lossless compression for the rest of the image. In this method of compression, PSNR obtained is remarkable and compression ratio can be increased by increasing the base value which is in power of two. Image compression is essential where images need to be stored, transmitted or viewed quickly and efficiently. The artificial neural network is a recent tool in image compression as it processes the data in parallel and hence requires less time and is superior over any other technique. The reason that encourage researchers to use artificial neural networks as an image compression approach are adaptive learning, self-organization, noise suppression, fault tolerance and optimized approximations. In this method of compression, medical image will be compressed completely loss less by using morphological operations. In this paper region of interest (ROI) is detected by Artificial Neural Network (ANN) & then compress the part of ROI using lossless method & the part other than ROI compressed by using lossy method. The reason, wavelet method of compression preferred for the rest of the image is, despite of insignificance of region of image other than ROI.

 Abstract

Enamel Island Technique Revisited An accurate interocclusal record and correct mounting of the casts on an adjustable articulator allows proper alignment of the opposing teeth, creation of anatomic details and accurate intercuspation of the teeth post rehabilitation. It is easier to articulate the casts without a record when they can be accurately related by hand into maximum intercuspation. In the absence of definitive occlusal contacts, a definitive interocclusal record is required to articulate the maxillary & the mandibular teeth. This becomes even more important when the distal most tooth in the arch is to be prepared as an abutment for a fixed partial denture. This article describes the enamel island technique of making an accurate interocclusal record when the most distal tooth is an abutment for a fixed partial denture. In this method a centric stop or vertical stop is prepared on the distal abutment to maintain the vertical dimension of occlusion and to act as third point of reference for a stable occlusal relationship when occluding the definitive casts on articulators.

 Abstract

To increase reliability and quality of the product at low cost, machine must work without any failure. To avoid unplanned downtime due to sudden failure of spindles, condition monitoring is very essential. Condition monitoring is the process of monitoring a parameter of condition in machinery (vibration), in order to identify a significant change. This project focuses on the condition monitoring of spindle. In this project changes in the machine conditions (vibrations) are detected automatically in real time by using online vibration monitoring system. If the spindle vibration increases quality of the product is affected. This system helps to overcome this problem Vibration measurement sensor (accelerometers) is mounted on spindle which is used to sense the vibration of a spindle .Data acquired from the sensor is collected by IMX-8, which is a vibration monitoring device used for continuous analysis and monitoring. It has different modes and on-board memory for local device data storage and data analysis via the app SKF @ptitude observer. IMX-8 is connected to HMI through Modbus. The biggest benefit of Modbus protocol is that it supports communication speed up to 115 kbps. For human machine interface, Mitshibushi HMI is used to display the status of a machine.HMI screens are designed by using GT Designer-3 software which is used for continuous monitoring and graphical view of vibration.IMX-8 and GSM modem is connected through Ethernet which provides high speed data transmission. This acquired data can be accessed remotely by administrative office or clients.
