Robot Hazards Introduction: the aim of this assignment is to gain general awareness and an understanding of the legal requirements and responsibilities that are involved in the safe working practices associated with robotic assisted manufacture. This is to be achieved by the identification of associated hazards with robotic applications and provide an understanding of how these hazards are overcome. Typical sources of hazards associated with robotic operations within the working environment include

the diode have zero voltage drop when on and zero current flow when off and the inductor has zero series resistance. Further‚ it is assumed that the input and output voltages do not change over the course of a cycle (this would imply the output capacitance as being infinite). [edit]Concepts The conceptual model of the buck converter is best understood in terms of an inductor’s "reluctance" to allow a change in current. Beginning with the switch open (in the "off" position)‚ the current in

Physics of a Guitar (Rough Draft) The guitar is the most played instrument in the music world. The oldest surviving guitar is thought to be made around 1776 in Italy by Gaetano Vinaccia. Though‚ the guitar looks like a simple instrument to construct or play there is a lot of physics behind the creation of it‚ from the strings to the air inside‚ the anatomy‚ and the sound spectrum. There are three types of guitars that are made: nylon acoustic‚ steel-string‚ and electric. Acoustic guitars produce

interconnect delays are governed by manufacturing Process (P)‚ operating Voltage (V) and ambient Temperature (T) properties of dies. These factors determine the physical properties of cells and interconnect like W/L ratio of cells and Resistance (R) and Capacitance (C) value of interconnects. At the 180-nm technology node and above‚ timing signoff at worst and best standard cell PVT corners with 2 RC extraction corners‚ namely‚ Cmax Rmin (Cmax) ‚ and Cmin Rmax ( Cmin) was sufficient.

Electronic WorkBench tutorial Introduction Electronic WorkBench (EWB) is a simulation package for electronic circuits. It allows you to design and analyze circuits without using breadboards‚ real components or actual instruments. EWB’s click-anddrag operations make editing a circuit fast and easy. You can change parameters and circuit components on the fly‚ which make "what-if" analysis straight foreward. This tutorial is intended as a quick introduction to EWB’s basic features. It first
