In this article we present both a theoretical framework and a solved example for pricing an European gas storage facility and computing the optimal strategy for its operation. As a representative price index we choose the Dutch TTF day-ahead gas price. We present statistical evidence that the volatility of this index is time-varying, so we introduce a new continuous-time model by incorporating ...

changes in proximate composition, colour and textural characteristics of ozone-processed shrimp as affected by combined effects of increasing ozone exposures and iced storage were investigated and for the first time. whilst proximate composition comprised of fat, moisture, and protein contents and colour comprised of l*, a*, b* and metric chroma (c), the texture comprised of adhesiveness, fract...

This paper investigates the impact of service quality in e-tailing on site visits and consumer demand (approximated by the last-clickthrough concept). We use a large representative data set obtained from a price-comparison site which covers most of the national (Austrian) market on e-tailing. Customers’ valuations for a broad range of 15 different service characteristics are condensed by factor...

Bendungan merupakan kontruksi yang berupa urugan tanah, batu, beton, dan atau pasangan batu dibangun selain untuk menahan serta menampung air, dapat juga limbah tambang tailing, lumpur sehingga terbentuk waduk. berperan sebagai faktor meningkatkan kemampuan (capacity) dalam menurunkan resiko terhadap bencana, bendungan pula menjadi sebuah ancaman bencana (hazard) baru. Dengan menggunakan Metode...

CO2-Plume Geothermal (CPG) power plants can use geologically stored CO2 to generate electricity. In this study, a Flexible Plume (CPG-F) facility is introduced, which provide dispatchable power, energy storage, or both and storage simultaneously—providing baseload with for demand response. It found that CPG-F deliver more than CPG plant, but less daily production. For example, the produces 7.2 ...

The specific hydrogeoecological conditions of aquifers some technogenic formations, mainly iron ore skarn-magnetite and titanium-magnetite are considered. resulting wastes, which stored in waste disposal sites during development deposits, due to the impact a number factors (natural technogenic) form waters. Waste facilities complex engineering structures (dumps sludge storages), turn create the...
