  3. 7. Interplay Between Environment and Genes on Morphological Variation in Perch – Implications for Resource Polymorphisms

    Författare :Jens Olsson; Peter Eklöv; Mats Björklund; Richard Svanbäck; Andrew P. Hendry; Uppsala universitet; []
    Nyckelord :Ecology; Perch; Resource polymorphism; Genetic differentiation; Phenotypic plasticity; Morphology; Competition; Character divergence; Behavior; Growth rate; Resource level; Gut lenght; Ekologi;

    Sammanfattning : Recent research has suggested that individual specialization within populations could be substantial and more common than previously acknowledged. Eurasian perch is one of many species of fish in lakes of postglacial origin that displays a morphological and dietary variation tightly coupled to the littoral and pelagic habitats of the lake.

  4. 8. Multiantenna Cellular Communications : Channel Estimation, Feedback, and Resource Allocation

    Författare :Emil Björnson; Björn Ottersten; Mats Bengtsson; Marios Kountouris; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; channel estimation; limited feedback; multicell communications; resource allocation;

    Sammanfattning : The use of multiple antennas at base stations and user devices is a key component in the design of cellular communication systems that can meet the capacity demands of tomorrow. The downlink transmission from base stations to users is particularly limiting, both from a theoretical and a practical perspective, since user devices should be simple and power-efficient, and because many applications primarily create downlink traffic (e.

  5. 9. A Resource-Aware Framework for Designing Predictable Component-Based Embedded Systems

    Författare :Aneta Vulgarakis; Ivica Crnkovic; Paul Pettersson; Cristina Seceleanu; Elisabetta Di Nitto; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; component-based development; formal analysis; embedded systems; resource prediction; behavioral modeling; architectural modeling; tools; resource-aware framework; Computer Science; datavetenskap;

    Sammanfattning : Managing complexity is an increasing challenge in the development of embedded systems (ES). Some of the factors contributing to the increase in complexity are the growing complexity of hardware and software, and the increased pressure to deliver full-featured products with reduced time-to-market.

  7. 10. Reproductive allocation and costs of reproduction in subarctic herbs : A resource-based perspective

    Författare :Åsa M. Hemborg; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecology; Altitudinal gradient; Plant size; Predispersal seed predation; Reproductive effort; Resourcedynamics; Seasonal variation; Sexual dimorphism; Somatic costs; Unisexual plants; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi; ekologisk botanik; Ecological Botany;

    Sammanfattning : The influence of internal and external factors on two major plant life history components, i.e., reproductive allocation and costs of reproduction, was examined for nine perennial herbs in subarctic Swedish Lapland. In one study, comparisons were made between Sweden and the French Alps. LÄS MER
