A STUDY ON WEAR AND EROSION PROPERTIES OF RAIL STEEL



Introduction:
Steels represent the most important group of engineering materials as they have the widest diversity of applications of any of the engineering materials. Generally, carbon is the most important element profoundly affecting the mechanical properties of the steels. The term steel is used for many different alloys of iron. These alloys vary both in the way they are made and in the proportions o ....etc

VARIATION OF DAMPING RATIO AND SHEAR MODULUS WITH PLASICITY INDEX AND CONFINING PRESSURE

INTRODUCTION
Behaviour of soil under cyclic loading is non-linear

Non-linear behaviour commonly characterised by:

Damping coefficient, D

Shear modulus, G


DEFINITION
Damping coefficient
Is defined as the measure of energy dissipation
Shear modulus
Is the ratio of shear stress to shear strain
Plasticity index
Is the difference between liquid limit and plastic
limit
Confining pre ....etc

Abstract”
In This paper investigates the impact of a STATCOM operating in a phase imbalanced mode on damping sub synchronous resonance in series capacitive compensated transmission grid. Phase imbalance has the potential of reducing the energy exchange between the electrical and mechanical sides of turbine-generator and, therefore, damps the sub synchronous oscillations resulting from series capacitive compensation.

PROTECTIVE COATINGS FOR CONCRETE BRIDGES



Protection of structures is very important for increasing the life of the structure. There is a growing national concern about premature deterioration of our concrete infrastructure projects such as bridges, aqueducts etc. requiring early repair and/or replacement. Use of protective coatings will increase the durability and hence the life of these structures. As most of these structures are made up of concrete and steel, the role that coatings play in protecting the s ....etc

Fuzzy Coordination of FACTS Controllers for Damping Power System Oscillations

Abstract
This paper concerns the optimization and coordination of the conventional FACTS (Flexible AC Transmission Systems) damping controllers in multimachine power system. Firstly, the parameters of FACTS controller are optimized. Then, a hybrid fuzzy logic controller for the coordination of FACTS controllers is presented. This coordination method is well suitable to series connected FACTS devices like UPFC, TCSC etc. in damping multi-mod ....etc

INTRODUCTION
Protective relaying is an integral part of any electrical power system. The fundamental objective of system protection is to quickly isolate a problem so that the unaffected portions of the system can continue to function. The flip side of this objective is that the protection system should not interrupt power for acceptable operating conditions, including tolerable transients.
• The choice of protection depends upon several aspects such as type, rating of the protected equip ....etc

Abstract
This paper focuses on the experimental investigation carried out on high strength concrete reinforced with hybrid fibres (combination
of hooked steel and a non-metallic fibre) up to a volume fraction of 0.5%. The mechanical properties, namely, compressive strength, split
tensile strength, flexural strength and flexural toughness were studied for concrete prepared using different hybrid fibre combinations –
steel–polypropylene, steel–polyester and steel–glass. The flexural properties were studied using four point ben ....etc
