Well Testing, Methods and Applicability

Well testing is widely used today in water wells, oil and gas wells, for geothermal applications, within civil engineering projects, thermal storage and CO2 storage. The overall testing goal is to verify the productivity from a well and/or for characterization of hydraulic and thermal properties, as well as the spatial limitations of an aquifer. There are three major methods for conducting well te

En utbildningsgaranti – möjligheter på regional nivå

Trots att gymnasiekompetensen är stark sammanlänkad med ungdomarnas framtida försörjnings- och etableringsmöjligheter framträder det i Skåne en dyster bild gällande ungdomarnas studieresultat (dock stora skillnader mellan kommunerna). Nästan hälften av Skånes kommuner ligger under riksgenomsnittet. När det gäller andelen elever som i årskurs 9 har uppnått målen i samtliga ämnen under våren 2013 är

Reducing Memory in Software-Based Thread-Level Speculation for JavaScript Virtual Machine Execution of Web Applications

Thread-Level Speculation has been used to take advantage of multicore processors in virtual execution environments for the sequential JavaScript scripting language. While the results are promising the memory overhead is high. Here we propose to reduce the memory usage by limiting the checkpoint depth based on an in-depth study of the memory and execution time effects. We also propose an adaptive h

Dramatic orientation shift of white-crowned sparrows displaced across longitudes in the high arctic

Advanced spatial-learning adaptations have been shown for migratory songbirds (1], but it is not well known how the simple genetic program encoding migratory distance and direction in young birds [2-4] translates to a navigation mechanism used by adults [2, 4-6]. A number of convenient cues are available to define latitude on the basis of geomagnetic and celestial information [7-15], but very few

Load demand pricing - Case studies in residential buildings

Since the liberalisation of the Swedish electricity market in 1996, the competition between utilities has increased, and the generation capacity has gradually been adjusted to suit the demand. Consequently, the earlier excessive electricity production capacity has been reduced. However, if the gap between the generation capacity and demand will be too narrow, this may result in notable power short
