  1. 1. Steady State Operation and Control of Power Distribution Systems in the Presence of Distributed Generation

    Author : Ferry Viawan; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; distance protection; stochastic assessment; voltage dip; line drop compensation; distribution systems; on-load tap changer; overcurrent protection; sensitive equipment; voltage dip immunity; voltage control; short circuit; reactive power control; pilot protection.; protection coordination; protection; Distributed Generation; losses;

    Abstract : In this thesis, the impact of distributed generation (DG) on steady state operation and control of power distribution systems is investigated. Over the last few years, a number of factors have led to an increased interest in DG schemes. DG is gaining more and more attention worldwide as an alternative to large-scale central generating stations. READ MORE

  2. 2. Towards sustainability of environmental protection : recovery of nutrients from wastewater filtration and the washing of arsenic contaminated soils

    Author : Lea Rastas Amofah; Luleå tekniska universitet; []

    Abstract : Conventional methods for wastewater treatment and remediation of the sites withcontaminated soils focus on protection of human health, receiving waters and theenvironment. Towards this end, these methods concentrate on the reduction or removal of polluting substances, and therefore, are not well suited for creating resources through the recovery of nutrients, energy and decontaminated soils.

  3. 3. Protecting forests through partnerships

    Author : Ulrika Widman; Camilla Sandström; Eeva Primmer; Umeå universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; forests; formal protection; forest owners; public-private partnerships; Nature Conservation Agreements; the Komet program; forest governance; Sweden; statskunskap; political science;

    Abstract : This thesis addresses the potential of private-public partnerships (PPPs) to involve private forest owners in formal forest protection. These partnerships have been widely advocated as means to engage actors from diverse sectors in collaborative new relationships, formed in a step-wise manner, to improve management of resources that combine public and private goods.

  4. 4. Valorization of herring filleting co-products to silage - Control of protein hydrolysis and lipid oxidation during ensilaging and possibilities for separating herring silage into multiple products

    Author : Mursalin Sajib; Chalmers University of Technology; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; lipid oxidation; separation; ensilaging; antioxidants; by-products; protein hydrolysis; fish oil; pilot-scale; valorization; Herring Clupea harengus ; silage;

    Abstract : Industrial processing of herring ( Clupea harengus ) into convenience products such as fillets generates around 60% co-products being rich in both protein and n-3 polyunsaturated fatty acids (PUFAs). A promising cost-efficient strategy to valorize these raw materials into food and/or feed ingredients would be to apply ensilaging, i.e. READ MORE

  5. 5. Turbo Codes and Channel Estimation in Wireless Systems

    Author : Bartosz Mielczarek; Chalmers University of Technology; []
    Keywords : adaptive coding; turbo codes; PSAM; timing offset; BCJR algorithm; synchronization; channel estimation; phase offset; Wiener filters; unequal error protection; OFDM;

    Abstract : This thesis focuses on practical implementation issues of turbo codes with imperfectly estimated fading wireless channels and limited code length. Channel estimation can be divided into estimation of static parameters, such as constant timing and phase offset, and dynamic parameters, such as fading channel amplitudes. READ MORE
