Abstract—We present an approach and a system to let tutors
monitor several important aspects related to on line tests, such
as learner behavior and test quality. The approach includes the
logging of important data related to learner interaction with the
system durin ....etc

NDT TESTS ON CONCRETE

Rebound Tests
The rebound hammer is a surface hardness tester for which an empirical
correlation has been established between strength and rebound number.
The only known instrument to make use of the rebound principle for
concrete testing is the Schmidt hammer, which weighs about 4 lb (1.8 kg)
and is suitable for both laboratory and field work. It consists of a springcontrolled
hammer mass that slides on a plunger within a tubular housing.
The hammer is forced against the surface of the concrete by ....etc

Abstract:
The aerospike engine is a type of rocket engine that maintains its aerodynamic efficiency across a wide range of altitudes through the use of an aerospike nozzle. It is a member of the class of altitude compensating nozzle engines. A vehicle with an aerospike engine uses 25“30% less fuel at low altitudes, where most missions have the greatest need for thrust. Aerospike engines have been studied for a number of years and are the baseline engines for many single-stage-to-orbit (SSTO) designs and were also a strong contender for t ....etc

IDENTIFICATION OF UNDER WATER VEHICLE HYDRODYNAMIC EFFICIENTS USING FREE DECAY TESTS



INTRODUCTION
In recent years there has been an ever increasing number
of applications for unmanned underwater vehicles
(UUV) in various tasks, for instance in surveying and
exploration, or in missions such as the positioning
of underwater laboratories (Aguiar 1997). Improvements
in the evaluation of the hydrodynamic models
of UUV’s result in more effective control s ....etc

Ceramic Ball Bearing Performance Tests



A New Ball Bearing

INTRODUCTION:
Want to save a *million barrels of petroleum a day by simply changing to a more
efficient ball bearing in machinery? Sounds too good to be true, but it’s possible with
new materials available today.
Tribology – The science of friction and wear.
If we look at the surface finish of a metal ball or race very closely, peaks and valleys
appear over these surfaces. I ....etc

Abstract
According to the relevant IEC standards vacuumcircuit-breakers have to meet various needs, e.g. theinterruption capability, making operations, and dielectricstrength. Switching of capacitor banks, overhead lines, orcables leads to very small currents in comparison withshort-circuit currents. After current interruption thecircuit-breaker must withstand twice the peak value of thesystem voltage. Furthermore, restrikes can lead to voltagemultiplication. The conjunction of relatively smallbreaking currents with high voltage stress ....etc
