applications of laser in industry and medical field latest ppt download

Abstract

Many scientific, military, medical and commercial laser applications have been developed since the invention of the laser in 1958. The coherency, high monochromaticity, and ability to reach extremely high powers are all properties which allow for these specialized applications.

Medical Uses of Lasers

The highly collimated beam of a laser can be further focused to a microscopic dot of extremely high energy density. This makes it useful as a cutting and cauterizi ....etc

COUPLED FIELD ANALYSIS OF A WELDED JOINT


Introduction

Welding
Welding is the process used to join two or more pieces of metal together by applying thermal energy or pressure. It is a precise, reliable, cost-effective method for joining materials. This technique is widely used by manufactures to join metals and alloys.

Welding geometry
The weld geometry is chosen considering the welding process and thickness of the workpiece. It is important to choose a geometr ....etc

ABSTRACT
With a 100-year head start over more modern screen technologies, the CRT is still a formidable technology. It s based on universally understood principles and employs commonly available materials. The result is cheap-to-make monitors capable of excellent performance, producing stable images in true colour at high display resolutions. But in the world of miniaturization, Cathode ray tubes (CRT) are giant dinosaurs waiting for extinction. A CRT uses a single-point hot electron source that is scanned across the screen ....etc

Mobile Sampling of Sensor Field Data Using Controlled Broadcast

ABSTRACT:
Mobile objects can be used to gather samples from a sensor field. Civilian vehicles or even human beings equipped with proper wireless communication devices can be used as mobile sinks that retrieve sensor-data from sampling points within a large sensor field. A key challenge is how to gather the sensor data in a manner that is energy efficient with respect to the sensor nodes that serve as sources of the sensor data. In this paper, an alg ....etc

The trend in VLSI towards single-chip systems leads to the integration of analog and digital functions on a single chip. Field-programmable devices also follow the same trend. Currently, there are many digital field-programmable devices in existence like Field Programmable Gate Arrays (FPGA), and more recently Field Programmable Analog Arrays have been developed. Field-Programmable Analog Array, usually abbreviated FPAA, is the analog equivalent of the FPGA, a digital programmable device. It is an integrated circuit which can be configured to i ....etc

ABSTRACT

Point&Connect (P&C) offers an intuitive and resilient device pairing solution on standard mobile phones. Its operation follows the simple sequence of point-and-connect: when a user plans to pair her mobile phone with another device nearby, she makes a simple hand gesture that points her phone towards the intended target. The system will capture the user s gesture, understand the target selection intention, and complete the device pairing. P&C is intention based, intuitive, and reduces user efforts in device pairing. The m ....etc
