In mobile ad hoc networks wireless nodes communicate over multi hop links and are capable of movement. This paper evaluates a solution that provide these networks with Internet Access and the capability to roam between different access points. Design and implemenation consideration are discussed that focus on behaviour and criterias for performing handover. Simulation result show that the main fac

This paper draws on studies of current knowledge on health policy processes in Cambodia, China and Lao PDR by a number of researchers in the POVILL Consortium. They are based on reviews of international and national literature and of policy documents, interviews with key informants and preliminary findings of small studies in a selection of rural localities. It explores why policy makers have beco

This licentiate thesis builds on an interest in scholarly communication and social networks within in library and information science, in particular in the area of information seeking and use. The specific purpose is to create a scientifically founded understanding of how the interaction of caring scientists in social networks contributes to the scientists sense-making in their research practice.

The article constitutes a landscapearchaeological analysis of the prehistoric time in the Helsingborg area, covering chronologically the Stone Age, the Bronze Age and the Iron Age. A basic approach to interprete the archaeological fragments and their cultural context is that they come from oral cultures. To give an idea of the area's prehistory comparisons with other geographical areas, cultures a

Testing is used to ensure high quality chip production. High test quality implies the application of high quality test data; however, the technology development has lead to a need of an increasing test data volume to ensure high test quality. The problem is that the test data volume has to fit the limited memory of the ATE (Automatic Test Equipment). In this paper, we propose a test data truncatio

Popular Abstract in Swedish Syftet med detta arbete har varit att utveckla nya, stabila bränsleelektroder till bränsleceller baserade på fasta oxider, SOFC (solid oxide fuel cells). Vi har undersökt olika keramiska material eller kompositer med lovande egenskaper för att användas på anodsidan av bränslecellerna. För att förbättra redox-stabiliteten så ska bränsleelektroden företrädesvis inte innehThe purpose for this work has been to develop new robust fuel electrodes for solid oxide fuel cells (SOFC). The aim was to find suitable ceramic materials or composites with promising properties for the use as SOFC anodes. Preferably, the electrode should not contain any metal (or at least a metal should not be a major component) in order to improve the redox properties. The present work focuses o

Hydrogeological and geophysical methods were applied in the Río Artiguas watershed, a mountain basin located in central Nicaragua. This area is under environmental stress from anthropogenic activities like gold mining using mercury and waste disposal into the streams. The aim of this work was to characterise the hydrogeological conditions in the basin with emphasis on understanding the possible co

Popular Abstract in Swedish Avhandlingens övergripande syfte var att under ett ettårigt nationellt projekt för utveckling av geriatrisk rehabilitering, Rehab Äldre 300, redogöra för förändringar av kvaliteten inom geriatrisk rehabilitering samt att beskriva denna utifrån administrativ-, personal- och vårdtagar-nivå. Vidare var syftet att under utvärderingsperioden beskriva förändringar av vårdtagaThe overarching aim of this thesis was to report changes in the quality of geriatric rehabilitation as perceived by administration, caregivers, and clients during a one-year period of a Swedish governmental venture of development in geriatric rehabilitation. Further aims were to describe changes in clients’ prevalence of symptoms, ADL dependence, subjective well-being in a one-year follow-up and t
