Abstract While the share of renewable energy sources increased within last years with an ongoing upward trend, sector is facing problem storing large amounts electrical properly. To compensate daily and seasonal fluctuations, a sufficient storage system has to be developed. The hydrogen in subsurface, referred as Underground Hydrogen Storage (UHS), shows potential solution for this problem. Hyd...

Hydraulic fracturing is one of the most common methods of well stimulation for reservoirs with low permeability. Hydraulic fracturing increases the flow capacity, alters flow geometry, bypasses damage and improves recovery factor. The pressure of most of Iranian oil reservoirs is declined and consequently the production is reduced. It is necessary to improve the production by using new stimulat...

The Single-Pass Language-Driven Incremental Compilation (SLIC) strategy uses a series of model-to-model (M2M) transformations to compile a model or program to a specified target. Tool developer and modeler can inspect the result of each transformation step, using a familiar, graphical syntax of the successively transformed model, which is made possible by harnessing automatic layout. Previous w...

The main idea behind Reconfigurable Object Nets (RONs) is to support the visual specification of controlled rule-based net transformations of place/transition nets (P/T nets). RONs are high-level nets with two types of tokens: object nets (place/transition nets) and net transformation rules (a dedicated type of graph transformation rules). Firing of high-level transitions may involve firing of ...

OBJECTIVE To examine the plausibility of health claims for Eclipse, a novel smoking article being marketed by the RJ Reynolds Tobacco Company (RJR) as potentially reducing the risk of cancer and other diseases compared to conventional cigarettes. DATA SOURCES A company product website (www.eclipse.rjrt.com) summarising scientific studies of various versions of Eclipse, and the published revie...

We report secondary eclipse photometry of two hot Jupiters, WASP-48b and HAT-P-23b, at 3.6 and 4.5μm taken with the InfraRed Array Camera aboard the Spitzer Space Telescope during the warm Spitzer mission and in the H and KS bands with the Wide Field IR Camera at the Palomar 200 inch Hale Telescope. WASP-48b and HAT-P-23b are Jupiter-mass and twice Jupiter-mass objects orbiting an old, slightly...

The light curves of the pre-main-sequence star KH 15D from the years 1913– 2003 can be understood if the star is a member of an eccentric binary that is encircled by a vertically thin, inclined ring of dusty gas. Eclipses occur whenever the reflex motion of a star carries it behind the circumbinary ring; the eclipses occur with period equal to the binary orbital period of 48.4 days. Features of...

A total eclipse occurred on 11 August 1999 with its path of totality passing over central Europe in the latitude range 40–50 N. The ionospheric responses to this eclipse were measured by a wide ionosonde network. On the basis of the measurements of foE, foF1, and foF2 at sixteen ionosonde stations in Europe, we statistically analyze the variations of these parameters with a function of eclipse ...
