  1. 16. Cryptic Female Choice and Male Mating Behaviour : Sexual Interactions in Beetles

    Författare :Martin Edvardsson; Göran Arnqvist; Paul Ward; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; Cryptic female choice; Copulatory courtship; Harmful male traits; Nuptial gifts; Sperm competition; Sexual selection; Tribolium castaneum; Callosobruchus maculatus; Biologi; Biology; Biologi;

    Sammanfattning : The importance of cryptic female choice, i.e. female post-copulatory influence over male reproductive success, in driving the evolution of male traits remains controversial. The main aim of this thesis was to understand the post-copulatory consequences of sexual interactions and the importance of cryptic female choice in two species of beetle. LÄS MER

  2. 17. Protecting Ecological Integrity in Transboundary Watercourses : An Integrational Approach towards Implementing Environmental Flows

    Författare :Josefin Gooch; Juridiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; environmental law; international law; miljörätt; folkrätt;

    Sammanfattning : The thesis explores the obligation in international law to protect the ecological integrity of transboundary watercourses. The thesis specifically examines the obligation to protect environmental flows, which essentially means to protect a certain water flow for the benefit of freshwater ecosystems and the ecosystem services they supply.

  3. 18. Optimal Braking Patterns and Forces in Autonomous Safety-Critical Maneuvers

    Författare :Victor Fors; Lars Nielsen; Björn Olofsson; Jan Åslund; Mathias Lidberg; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The trend of more advanced driver-assistance features and the development toward autonomous vehicles enable new possibilities in the area of active safety. With more information available in the vehicle about the surrounding traffic and the road ahead, there is the possibility of improved active-safety systems that make use of this information for stability control in safety-critical maneuvers.

  4. 19. On-chip electrochemical capacitors and piezoelectric energy harvesters for self-powering sensor nodes

    Författare :Agin Vyas; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy storage; 2DOF; sensor node; Energy harvesting; piezoelectric energy harvesters; graphene oxide; spin coating; MEMS; Microsupercapacitors;

    Sammanfattning : On-chip sensing and communications in the Internet of things platform have benefited from the miniaturization of faster and low power complementary-metal-oxide semiconductor (CMOS) microelectronics. Micro-electromechanical systems technology (MEMS) and development of novel nanomaterials have further improved the performance of sensors and transducers while also demonstrating reduction in size and power consumption.
