INTRODUCTION
Gas springs provide controlled motion and speed for elements, such as lids and doors, that open and close. They typically rely on the fluid dampening of a gas such as nitrogen in the cylinder. Important performance specifications for gas springs include absorber stroke, compressed length, extended length, maximum force (P1), and maximum cycles per minute
The absorption or damping action for gas springs can be compression or extension. In a compression gas spring the shock absorption or dampening occurs in the compressio ....etc

ABSTRACT

The holddown Spring is one of the major components of a fuel assembly for PWR. It holds the fuel assembly firmly seated down on the lower core plate and allows the FA axial movement caused from the irradiation growth of guide thimbles. Depending on the up-lift force of a fuel assembly, from 2 to 4 leaves are assembled to be a set of a spring pack and it is fixed on the frame of the top end piece by screw. The spring can deflect so greatly during operat ....etc

GAS SPRINGS
ABSTRACT
Gas springs provide controlled motion and speed for elements, such as lids and doors, that open and close. The absorption or damping action for gas springs can be compression or extension. In a compression gas spring the shock absorption or dampening occurs in the compression direction. In an extension gas spring the shock absorption or dampening occurs in the extension direction. Important physical specifications for gas springs include the cylinder diameter or maximum width, the rod diameter, mounting, and body materi ....etc

ABSTRACT
Security can only be as strong as the weakest link. In this world of cryptography, it is now well established, that the weakest page link lies in the implementation of cryptographic algorithms. This project deals with RSA algorithm implementation with and without Chinese Remainder Theorem and also using Variable Radix number System. In practice, RSA public exponents are chosen to be small which makes encryption and signature ....etc

Introduction
In the mobile communication, in the past decade, the industry has grown
significantly. In the past, the mobile unit has only for voice communication, it
has changed and more band and applications are need in a mobile phone
which may lead the mobile phone has multiple antenna.
In the mean time, the most of the mobile phone has been in internal antenna
elements instead of external whip and helix antennas use ....etc

Abstract


This work presents a novel algorithm using color contrast enhancement and lacuna texture synthesis is proposed for the virtual restoration of ancient Chinese paintings. Color contrast enhancement based on saturation and de-saturation is performed in the u'v'Y color space, to change the saturation value in the chromaticity diagram, and adaptive histogram equalization then is adopted to adjust the luminance component. Additionally, this work presents a new patching method using the Markov Random Field (MRF) model of texture synthes ....etc

ABSTRACT
A gas spring is a type of spring that, unlike a typical metal spring, uses a compressed gas, contained in a cylinder and compressed by a piston, to exert a force. Gas springs are used in automobiles, where they are used to support the weight of doors while they are open. They are also used in furnit ....etc
