  2. 16. Locating Biotech Innovation : Places, Flows and Unruly Processes

    Author : Henrik Mattsson; Anders Malmberg; Dominic Power; Peter Dicken; Uppsala universitet; []
    Keywords : Social and economic geography; Biotech; Biotechnology; Innovation; Creativity; Clusters; Innovation systems; Technology policy; Regional development; Economic spaces; Time-geography; Time-space; Mobility; Knowledge; Knowledge workers; Agglomeration; Talent; Biotech firms; Innovation Policy; Kulturgeografi;

    Abstract : This thesis begins by making two observations. First, that the regional economic landscapes in which we all live our daily lives, and which provide the basis for employment and prosperity, are constantly changing. READ MORE

  4. 17. Scheduling Algorithms For Fault-Tolerant Real-Time Systems

    Author : Risat Pathan; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Online Scheduling; Partitioned Scheduling; Rate-Monotonic Scheduling; Multiprocessors; Uniprocessor; Task-Splitting Algorithms; Periodic Task Scheduling; Real-Time Systems; Fault-Tolerant Scheduling;

    Abstract : This thesis deals with the problem of designing efficient fault-tolerant real-time scheduling algorithms for independent periodic tasks on uni- and multiprocessor platforms. The well-known Rate-Monotonic (RM) scheduling algorithm is assumed as it is widely used in many commercial systems due to its simplicity and ease of implementation. READ MORE

  5. 18. Virtual Full Replication for Scalable Distributed Real-Time Databases

    Author : Gunnar Mathiason; Sten F. Andler; Sang H. Son; Hans Hansson; Alejandro Buchmann; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Scalability; Flexibility; Adaptiveness; Database Replication; Resource Management; Distributed Database; Real-time Database; Computer science; Datalogi; Information technology; Informationsteknik; Teknik;

    Abstract : A fully replicated distributed real-time database provides high availability and predictable access times, independent of user location, since all the data is available at each node. However, full replication requires that all updates are replicated to every node, resulting in exponential growth of bandwidth and processing demands with the number of nodes and objects added.

  6. 19. Searching for food in complex environments : Integrating processes at multiple spatial scales

    Author : Thomas Alexander Verschut; Peter Hambäck; Peter Anderson; Ring Cardé; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Associational effects; Natal experiences; Olfaction; Oviposition; Plant Ecology; växtekologi;

    Abstract : Resources are often unevenly distributed through the environment, resulting in a challenging task for insects to locate food, mates and oviposition sites. Consequently, there is an ongoing need to unravel how insects rely on behavioural and sensory traits while searching for resources in heterogeneous environments. READ MORE

  7. 20. Global Navigation Satellite Systems: Applications With Time Scales From Seconds to Decades

    Author : Tong Ning; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; elevation dependent systematic effects; atmospheric integrated water vapour; Global Navigation Satellite Systems;

    Abstract : Global Navigation Satellite Systems (GNSS) can be used formany applications with time scales varying from seconds to decades.For~example, due to the ability of high-rate sampling, GNSStechniques are suitable for the detection of the large co-seismicdisplacements, which are dominated by low-frequency signals andtherefore can be recorded at a few Hertz and estimated with rathersmall uncertainty (millimetres).
