The study was conducted in thirty renowned oil industries located in the selected cities of Marathawada region in Maharashtra state (Parbhani, Hingoli, Aurangabad, Jalna and Nanded) to know the inside and outside intensity level of noise. These oil industries were involved in expelling oil from cotton seeds for the last 10-12 years. All the selected oil industries were established by small and medium entrepreneurs. Measurement of noise level was made with a handy sound level meter (model no. 2013, serial no. F 04000) manufactured in India by CYGENT system.

This paper presents build a finite time observator (FTO) and applies it to the Almega 16 robot motion system. The main content of the article is to design a FTO so that the observation of the external noise of the Almega 16 robot motion system will converge to the desired true value over a period of time. finite, is done by estimating the external noise quantities and then feeding them into the available Robot controller.

Industrial garden is a new approach, especially for competition in increasing pollution in the atmosphere. It helps easily to beautify the industrial areas. The lawn laid in vacant lands not only adds beauty but also cut down dust. These gardens are designed to reduce pollution and beautify the world. These units are the most sources of air, water, noise and soil pollution.

In recent years, the microscopy technology for imaging cells has developed greatly and rapidly. The accompanying requirements for automatic segmentation and quantification of the imaged cells are becoming more and more. After studied widely in both scientific research and industrial applications for many decades, cell segmentation has achieved great progress, especially in segmenting some specific types of cells, e.g. muscle cells.

Tooth wear is a complex multifactorial process that involves the loss of hard dental tissue. Parafunctional habits have been mentioned as a self-destructive process caused by stress, which results in hyperactivity of masticatory muscles. Stress manifests itself through teeth grinding, leading to progressive teeth wear.

The thesis aims to propose some control techniques for mobile target Robot-camera. After that, I studied some of the torque control techniques of joints for the Robot-camera system sticking to the mobile target and the Robot-camera system, paying attention to the motivating motor sticking to the mobile target. Finally, the author also proposed some control algorithms for Robotic-camera arm system with irregular model, external noise and preventing system degradation, using nonlinear sliding controller (TSMC) in combination with Artificial neural networks to estimate uncertain numbers.

(BQ) The study used Taguchi dynamic approach coupled with a proposed ideal function model to optimize a high-speed EDM process for high geometrical machining precision and accuracy. The designed tool electrode including two basic geometries of square and circle as the distinct characteristics of workpiece is employed to help develop a versatile process for wider industrial applications. To enhance the speed and stability of EDM process, large discharge current is applied and aluminum (Al) powder added into the working fluid throughout the experiments.

This intuitive yet rigourous introduction derives the core results of digital communication from first principles. Theory, rather than industry standards, motivates the engineering approaches, and key results are stated with all the required assumptions. The book emphasizes the geometric view, opening with the inner product, the matched filter for its computation, Parseval's theorem, the sampling theorem as an orthonormal expansion, the isometry between passband signals and their baseband representation, and the spectral-efficiency optimality of quadrature amplitude modulation (QAM).

An emerging niche for the units is in the monitoring and observation of wildlife, which is noise sensitive and requires extended run times. These, alongside a low heat profi le, are also requirements of defence use and SFC has enjoyed a good relationship with the German Bundeswehr for many years. In March 2012 SFC expanded its military reach with the delivery of 50 FC 100 military APU systems to the US Army Operational Test Command. The EFOY Pro line experienced 24% growth from 2010 to 2011, though this was not enough to counterbalance the drop-off in leisure sales. Despite this, SFC’s.

In 2005 the National Academy of Engineering (NAE) held a workshop to review the present state of technology in noise control engineering. The workshop was organized by a steering committee charged with developing a prospectus for further studies of noise-related issues in the United States and to investigate how current technologies could be used to reduce exposures to noise. The issues framed by the steering committee were subsequently considered in a series of workshops held by NAE in 2007 and 2008...
