Although grinding is considered one of the more established manufacturing processes, it is still relatively poorly understood. In particular, the interaction of the wheel with the workpiece at times seems more like an art than a science. In this presentation, a 3-D topographic measurement approach which encompasses both the wheel and the workpiece will be presented. The topographic information obtained from the wheel will be applied to a model to predict the workpiece surface generated which will then be verified by experimentation. The prelimi ....etc

Abstract:
This project is an High precision digital thermometer which indicates the temperature on the seven segment display. It has an resolution of 0.06deg.The 1 wire temperature sensor IC from Maxim semiconductors is used as the sensor. The DS18S20 Digital Thermometer provides 9-bit centigrade temperature measurements and has an alarm function with nonvolatile user-programmable upper and lower trigger points. The DS18S20 communicates over a 1-wire bus that by definition requires only one data line (and ground) for communication with ....etc

DEVELOPMENT OF HIGH PRECISION SLOTTED ARRAY WAVE GUIDE ANTENNA FOR AEROSPACE APPLICATION
INTRODUCTION:
Missiles are guided towards the target through the seeker. Mono pulse antennas give the location of target. Thus tracking of the target depends upon the performance of the antennae.
The slotted wave guide array antenna offer various advantages like planar configuration and compact structure.
The performance of these antennae depends upon various parameters like slot ....etc

Abstract—
In this work we propose an innovative system for
tracking the sun which is based on the use of a commercial web
cam as the sensor element. An experimental electro-mechanism
was designed and developed to evaluate its accuracy and
efficacy in tracking the sun under different weather conditions.
The impact on the system performance caused by intermittent
cloud cover and temperature changes were also analyzed. The
system showed an accuracy of 0.1º and high immunity to
temperature variations. It demon ....etc

Variable Precision DSP Blocks in Stratix V Devices

This chapter describes how the variable precision digital signal processing (DSP)
blocks in Stratix® V devices are optimized to support higher-bit precision in
high-performance DSP applications, such as radar systems that must support higher
resolution and multi-antenna architectures, wireless-base station channel cards for
MIMO processing, medical and test applications for very high-precision filtering, and
fast Fourier transforms ....etc

PRECISION ENGINEERING & PRACTICE

1. INRODUCTION
There are three terms often used in precision practices and they are often used incorrectly or in a vague manner. The terms are accuracy, repeatability, and resolution. Because the present discussion is on machining and fabrication methods, the definitions will be in terms related to machine tools. However, these terms have applicability to metrology, instrumentation, and experimental procedures, as well.
1.1 Accuracy

Many scientific programs exchange large quantities of double-precision data between processing nodes and with mass storage devices. Data compression can reduce the number of bytes that need to be transferred and stored. However, data compression is only likely to be employed in high-end computing environments if it does not impede the throughput. This paper describes and evaluates FPC, a fast lossless compression algorithm for linear streams of 64-bit floating-point data. FPC works well on hard-to-compress scientific data sets and meets the thr ....etc
