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

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

Z-Wave

Z-Wave is the interoperable wireless communication standard developed by Danish company Zensys and the Z-Wave Alliance. It is designed for low-power and low-bandwidth appliances, such as home automation and sensor networks Radio specifications Bandwidth: 9,600 bit/s or 40,000 bit/s, fully interoperable Radio specifics In Europe, the 868 MHz band has a 1% duty cycle limitation, meaning that a Z-wave unit can only transmit 1% of the time.

This limitation is not present in the US 908 MHz ban ....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

Definition
Passive millimeter-wave (PMMW) imaging is a method of forming images through the passive detection of naturally occurring millimeter-wave radiation from a scene. Although such imaging has been performed for decades (or more, if one includes microwave radiometric imaging), new sensor technology in the millimeter-wave regime has enabled the generation of PMMW imaging at video rates and has renewed interest in this area. This interest is, in part, driven by the ability to form images during the day or night; in clear weather or in low- ....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
