The size, volume, variety, and velocity of geospatial data collected by geo-sensors, people, and organizations are increasing rapidly. Spatial Data Infrastructures (SDIs) are ongoing to facilitate the sharing of stored data in a distributed and homogeneous environment. Extracting high-level information and knowledge from such datasets to support decision making undoubtedly requires a relatively so

This thesis addresses challenges in increasing the robustness of cloud-deployed applications and services to unexpected events and dynamic workloads. Without precautions, hardware failures and unpredictable large traffic variations can quickly degrade the performance of an application due to mismatch between provisioned resources and capacity needs. Similarly, disasters, such as power outages and

TV-on-Demand service has become one of the most popular Internet applications that continuously attracts higher user interests. With rapidly increasing user demand, the existing network conditions may not be able to ensure low start-up delay of video playback. Prefetching has been broadly investigated to cope with the start-up latency problem which is also known as user perceived latency. In this

The purpose with this project was to create future self-service points for Skånetrafiken. The ticket machines that are in use today are difficult to interact with and excluding to people who are sight impaired or uses a wheelchair. Since Skånetrafiken are going to implement new self-service solutions in 2019 they want suggestions on how it could be designed. We thought that this project was an exc

Distributed e-Infrastructure is a key component of modern BIG Science. Service discovery in e-Science environments, such as Worldwide LHC Computing Grid (WLCG), is a crucial functionality that relies on service registry. In this paper we re-formulate the requirements for the service endpoint registry based on our more than 10 years experience with many systems designed or used within the WLCG e-In

For the past fifteen years, ever since the Court of Justice’s ruling in its landmark case Bosman, the sporting rules governing player mobility have been a hot topic. The ruling prohibited transfer fees for players out-of-contract thus putting an end to the restrictive transfer system hindering the free movement of football players. The Court also abolished the nationality restriction where clubs w

Phosphonated polymers may show high intrinsic proton conductivities at low water contents provided that the local concentration of phosphonic acid groups is very high [1,2]. Moreover, the lower acidity of aryl- and alkylphosphonic acids in relation to sulfonic acids requires higher acid contents to reach high conductivities also at higher water contents. In this context, poly(vinylphosphonic acid)

The Swedish Nuclear Fuel and Waste Management Company (SKB) has recently worked out a concept, KBS-3V, for disposal of highly radioactive waste in the form of spent reactor fuel and asked for the Government's approval and licensing. It implies blasting of tunnels at about 400 m depth and boring of large-diameter canister deposition holes extending vertically from the tunnel floor. The rock stresse

This paper presents a highly parallelized MIMO signal detection algorithm targeting vector-based reconfigurable architectures. The detector achieves high data-level parallelism and near-ML performance by adopting a vector-architecture-friendly technique - parallel node perturbation. To further reduce the computational complexity, imbalanced node and successive partial node expansion schemes in con

The fine-structure splittings of highly excited F-states in Cs were measured using high-resolution laser spectroscopy. The 12 and 132F states were found to be inverted with splittings ?E (122F)=-522(3) MHz and ?E (132F)=-416(3) MHz.

Gene sequences form the primary basis for understanding the relationships among extant plant groups, but genetic data are unavailable from fossils to evaluate the affinities of extinct taxa. Here we show that geothermally resistant fossil cuticles of seed-bearing plants, analysed with Fourier transform infrared (FTIR) spectroscopy and hierarchical cluster analysis (HCA), retain biomolecular suites

Parkinson's disease (PD) is a progressive neurodegenerative disorder caused by selective degeneration of the dopamine producing neurons in the substantia nigra. There is currently no clinically applicable therapy for treating or preventing Parkinsonian neurodegeneration. Great effort is put behind the development of novel therapeutic approaches that aim to alter the natural progression of the dise
