By a row (eg 24) LEDs fast spin at the right time and the individual LEDs on and off can make an image formed. This command is an extension of a project last year, with a hand made clock was built by a row of LEDs. The intention is now to provide a communication between the sash and the environment, different patterns can be read. The PC must have written a simple program that can convert a bitmap to control signals to LEDs. An additional challenge is different intensities for the LEDs to provide, eg through a revolution the LEDs to burn and th ....etc

Fuel Cell Plant Concept with Dynamic Characteristics of a Rotating Generator


Abstract Fuel cell plants will be powering future electrical
systems. Fuel cells normally generate direct current (DC) which
must be converted into Alternating Current (AC) for
transmission efficiency and for broader use by numerous loads of
different characteristics. An AC load consists of real power and
reactive power. The real power is generated by fuel cells.
However, the reactive power must be ....etc

Abstract
The main problem about a railway analysis is detection of cracks in the structure.
If these de ciencies are not controlled at early stages they might cause huge economical problems
a ecting the rail network (unexpected requisition of spare parts, handling of incident and/or
accidents). Within this framework, the early and continuous use of Non Destructive Tests can
be useful. In this context, Eddy Current Testing is increasing in importance and popularity.
Particularly, in this paper we exploit the measure of normal comp ....etc

Advances in High Temperature Superconductors (HTS) are enabling a new class of synchronous rotating machines (Super motors and Super generators) that can generically be categorized as Super machines. Compared to the conventional machines of equivalent rating, these Super machines are less expensive, lighter, more compact and efficient. The field windings are made with HTS conductor material which operates at 35-40 K and can be cooled with inexpensive cryocoolers. These advanced machines are attractive for use and at present they offer significa ....etc

Advances in High Temperature Superconductors (HTS) are enabling a new class of synchronous rotating machines (SuperMotors and SuperGenerators) that can generically be categorized as SuperMachines. Compared to conventional machines of equivalent rating, these SuperMachines are expected to be less expensive, lighter, more compact, efficient, and provide significantly superior stable operation in a power system. The field windings are made with HTS conductor material (BSCCO, or Bi-2223) which operates at 35-40 K and can be cooled with inexpensive, ....etc
