Lessons for Constellation from HST:
Adapting Human Spaceflight Vehicles to Achieve Multiple Goals in Space

Not long after the development of major elements of the Apollo program in the mid-1960's, engineers, managers, and scientists began to explore how those elements might be adapted to achieve additional priority national goals in space. Perhaps the best-known of these activities was the Apollo Applications Program, which in 1965 designed a modified lunar module that would permit astronaut-tended solar and astronomical observa ....etc

The unconventional method of several specific advantages over conventional methods of machining and these promise formidable tasks to be undertaken and set a new recording in the manufacturing technology. EDM is one such machining process, which has been immense help to the manufacturing process engineers to produce intricate shapes on any conducting metal and alloy irrespective of its hardness and toughness.

In electron-beam machining (EBM), electrons are accelerated ..
In electron-beam machining (EBM), electrons are accelerated to a velocity nearly three-fourths that of light.

The process is performed in a vacuum chamber to reduce the scattering of electrons by gas molecules in the atmosphere.

The stream of electrons is directed against a precisely limited area of the workpiece;

on impact, the kinetic energy of the electrons is converted into thermal energy that melts and vaporizes the material to be removed, forming holes or cuts.

The recent increase in the use of hard, high strength and temperature resistant materials in engineering necessitated the development of newer machining techniques. Conventional machining or finishing methods are not readily applicable to the new materials like hastalloy, nitralloy, waspalloy, nimonics, carbides, ceramics etc.


Conventional machining processes when applied to these newer materials:
1. Are uneconomical,
2. Produce poor degree of surface finish and accuracy,
3. Produce some stress,
4. Highly insufficient.

Newer machin ....etc

A SEMINAR ON
ADAPTIVE CONTROL MACHINING
ABSTRACT

Adaptive control system is a logical extension of the CNC-mechanism. In CNC mechanism the cutting speed and feed rates are prescribed by the part programmer. The determination of these operating parameters depends on the Knowledge and experience regarding the work piece, tool materials, coolant conditions and other factors.
By contrast in adaptive control machining, there is improvement in the production rate and reduction in t ....etc

Adapting Magnetic Resonant Coupling Based Relative Positioning Technology for Wearable Activitiy Recogniton
Abstract
We demonstrate how modulated magnetic field technologythat is well established in high precision, stationary motiontracking systems can be adapted to wearable activity recognition.To this end we describe the design and implementationof a cheap (components cost about 20 Euro for the transmitterand 15 Euro for the receiver), low power (17mA forthe transmitter and 40mA for the receiver), and easily wearable(the main size c ....etc
