A wide variety of the barrier crossing strategies exist among migrating songbirds, ranging from strict nocturnal flights to non-stop flights over a few days. We evaluate barrier crossing strategies in a nocturnally migrating songbird crossing the Mediterranean Sea and the Sahara Desert, the great reed warbler, exploring variation between the sexes and within individuals. We used data from 31 year-

Some seabirds we encounter only fleetingly, as they fly by as we walk along the beach, or perhaps meet far out at sea when we take a boat trip. Others though we are more familiar with, such as the ‘seagulls’ that many will not even turn their head to appreciate. Yet, all seabirds have remarkable stories to tell, and we are fortunate now to live at a time where we can follow individual birds as theMost seabirds breed colonially, at which time they make central-place foraging trips. Parents must collect food both for themselves and for egg production/chick-rearing. How should they forage? I followed five species across two sites in Sweden in the Baltic Sea using GPS and time-depth recorder (TDR) devices, giving information on both flight and diving activity. I use a movement ecology approach

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

Supramolecular hydrogels have attracted increasing attention in drug delivery, tissue engineering, and injectable biomaterials because of their high water content, good biocompatibility, and dynamic network structures. Cyclodextrin-based supramolecular systems can form network structures through host–guest interactions. These systems usually require mild cross-linking conditions and allow flexible

Nanoparticle-based targeted drug delivery holds promise for treatment of cancers. However, most approaches fail to be translated into clinical success due to ineffective tumor targeting in vivo. Here, the delivery potential of mesoporous silica nanoparticles (MSN) functionalized with targeting ligands for epidermal growth factor receptor and C─C chemokine receptor type 2 is explored in lung tumors

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

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

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
