the clinical and economic importance of heart failure is widely recognized.   the incidence of heart failure is on the increase, particularly with the aging of the population around the world.   it is time for a paradigm shift in heart failure management. alternative non-pharmacological strategies to remodel the failing ventricle will shape a major portion of heart failure therapy in the decade...

However, LNG carriers are expensive ships, and the contractual supply of cargo is usually tied by strict charterparty conditions. Therefore, the market has been hesitant to look at and accept other propulsion systems. Now this has changed. With the market launch of electronically controlled low speed diesels and reliable independent reliquefaction technology, all the traditional reasons not to ...

Demands for higher outputs have been met by careful tailoring of steam turbines for both mechanical and electrical power generation to meet the needs of thermal efficiency and reliability at an econoinic cost. Major system components and the methods chosen for speed control are described. Important operational requirements are featured.

After a presentation of the functionality of steam turbines of thermal power plants, we present the method of enthalpy difference used for the calculation of the steam turbine efficiency. This is why we present a stratification survey by circuit, by equipment and by organ. The objective is to determine the possible reasons for the deterioration of the heat rate of a thermal power plant at the l...

An extension diagnosis method based on the matter-element model and extended correlation function is presented for vibration fault diagnosis of steam turbine generators. First, the matter-element models of the vibration fault are built according to diagnostics derived from practical experience and then, vibration faults in steam-turbine generators can be directly identified by relation indices....

The railway as a means of transport is a very old idea. At its beginnings, it was mainly utilised in the central European mines with different means of traction being applied. But it did not come into general use until the invention of the steam engine. Since the 18th century it has developed faster and faster until in the 21st century it has become the most efficient means of transport for med...

Generative, model-based design of physical devices with multiple operating regions poses challenging problems . We present an approach for establishing region transitions of multi-operating region devices based on an analysis of the more basic shifts of the qualitative regions of quantities and their synchronization . The method takes as input design fragments, constructed by model-based design...
