Abstract:
Hydraulic accumulators are widely used in industry due to their ability to store energy and absorb fluid shock. Researchers have designed kinds of novel accumulators with better performance in these specific areas. However, the pressure in these accumulators decreases significantly when the fluid oil is continuously supplied from the accumulator to the hydraulic system. This limitation leads to a transient large pressure drop, especially in a small hydraulic system with varied working frequency. In this research, a combined piston type accumulator is proposed with a relatively steady pressure

Abstract:
Many power grid facilities require heating in winter. For their heating, they usually install a system of electric heaters, connect mini gas boilers or use the thermal emissions of working electrical installations, since these objects are often located away from the sources of central heating. This leads to additional costs for the organization's own needs. It is proposed to accumulate the excess heat generated by using a ground heat accumulator, which will allow you to accumulate heat in warm periods of the year and when there is an excess of thermal energy in the system, and then use the the

A thermal time-constant correlation based on experimental data is presented for gas-charged hydraulic accumulators. This correlation, along with the thermal timeconstant model, permits accurate prediction of accumulator thermodynamic losses and the gas pressure and temperature history during compression or expansion.

The correlation was developed from heat transfer data obtained with a 2.5 liter piston-type accumulator charged with nitrogen gas. Both horizontal and vertical orientations

Hydraulic piston accumulators play a major role especially within the field of stationary hydraulics.

Abstract:
We trace the effects of a devastating earthquake that occurred in Northern Pakistan in 2005. Using a new dataset from a survey conducted four years after the earthquake, we first show that the distance of the household from the fault line was not correlated with pre-existing household characteristics, while it was strongly predictive of earthquake-related damage and mortality. Through emergency relief aid, households living close to the fault line reported receiving substantial cash compensation that amounted to as much as 150% of their annual household consumption expenditure.

Abstract:
La fermeture des centrales nucléaires et le développement de l’énergie solaire et éolienne rendent la production d’électricité plus volatile. De nouveaux systèmes de stockage sont nécessaires pour s’assurer que l’électricité est disponible au moment où elle est nécessaire. Le stockage adiabatique d’air comprimé représente une technologie prometteuse. Il utilise l’excédent de production des installations solaires et éoliennes pour comprimer l’air ambiant et le stocker dans une cavité souterraine. Au besoin, l’air comprimé est à nouveau détendu et entraîne alors une turbine qui produit de l’élec
