High penetration (HP) Wind Diesel Hybrid Systems (WDHS) have three modes of operation: Diesel Only (DO), Wind Diesel (WD) and Wind Only (WO). The HP-WDHS presented in this article consists of a Wind Turbine Generator (WTG), a Diesel Generator (DG), the consumer Load, a Ni–Cd Battery based...

Field-ion microscopy and molecular dynamics simulation were used for the characterization of the translation states at special grain boundaries in tungsten. It is revealed that rigid-body displacement had the component of displacement parallel to the [110] direction equal to 0 or 1 interplanar...

A solar deep-freezing process has been designed. It aims at cooling down a cold box to about −20°C, using simple flat plate solar collectors operating at 70°C. This original process involves two cascaded thermochemical systems based on the BaCl2/ammonia reaction. Its working mode is...

In this paper the macro and structural implications of three alternative tariff-reduction strategies are examined. Under the first strategy, which is similar to that adopted in Australia in 1973, the tariff cut is implemented without warning. The second strategy is consistent with the current...

A numerical procedure has been applied for investigating the temperature distribution in a smooth tread bias tire of a light truck, operated under different speeds, pneumatic pressures, and loading conditions. Prior to simulation by the finite element analysis, two separate sets of testing,...

Shallow north part of the Caspian Sea is part of the most important region of the Caspian Sea. The Northeast part, especially its coastal zone, is unexplored areas of the Caspian Sea. In last years the north part of the Caspian Sea became one of the main sources of pollution of the whole sea....

This paper analyses the consequences of different tax policies upon the evolution of housing prices and residential capital stock (in the form of home ownership) in Spain. The framework is a computational aggregate model of housing as an asset. Policies under consideration are the removal of...

We argue that the main constraint for the Mexican economy to grow remains inside the structural deficit of the current account as well as in the real exchange rate level. An annual structural econometric model (1970-99) (estimated through weighted two-stage least squares) is estimated to...
