  2. 1. Thermal formation and chlorination of dioxins and dioxin-like compounds

    Author : Stina Jansson; Stellan Marklund; Mats Tysklind; Jochen F. Müller; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dioxin; dioxin-like compounds; isomer distribution pattern; homologue profile; injection; O2PLS; PCDD; PCDF; PCN; PCBz; PCPh; MSW combustion; formation; chlorination; flue gas; quench profiles; Environmental chemistry; Miljökemi;

    Abstract : This thesis contributes to an increased understanding of the formation of dioxins and dioxin-like compounds in combustion processes. Although emissions to air from waste incineration facilities have been greatly reduced by the use of efficient air pollution control measures, the resulting residues (ashes and filters) are highly toxic and are classified as hazardous waste.

  4. 2. Towards full Automation of Robotized Laser Metal-wire Deposition

    Author : Almir Heralic; Bengt Lennartson; Anna-Karin Christiansson; Giorgos Nikoleris; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laser metal wire deposition; process control; process development; optical sensors; robotic weld equipment; Manufacturing engineering; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Abstract : Metal wire deposition by means of robotized laser welding offers great saving potentials, i.e. reduced costs and reduced lead times, in many different applications, such as fabrication of complex components, repair or modification of high-value components, rapid prototyping and low volume production, especially if the process can be automated.

  5. 3. Forest edge development : management and design of forest edges in infrastructure and urban environments

    Author : Björn Wiström; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : This thesis investigates design guidelines and management systems for the development of stationary forest edges with a graded profile in infrastructure and urban environments. The spatial restriction for the edge to move forward caused by human land use counteracts the natural dynamics and development patterns of graded forest edges. READ MORE

  6. 4. Applications of the Virtual Holonomic Constraints Approach : Analysis of Human Motor Patterns and Passive Walking Gaits

    Author : Uwe Mettin; Anton Shiriaev; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Motion Planning; Humanoid Robots; Virtual Holonomic Constraints; Underactuated Mechanical Systems; Mechanical Springs; Automatic control; Reglerteknik;

    Abstract : In the field of robotics there is a great interest in developing strategies and algorithms to reproduce human-like behavior. One can think of human-like machines that may replace humans in hazardous working areas, perform enduring assembly tasks, serve the elderly and handicapped, etc. READ MORE

  7. 5. The missing links : Towards an Informed Substitution of Durable Water Repellent Chemicals for Textiles

    Author : Steffen Schellenberger; Ian Cousins; Stefan Stolte; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Durable water repellents (DWRs) that provide liquid repellency to functional textiles are part of an ongoing global substitution process. The process of substitution was initiated after DWRs based on side-chain fluorinated polymers (long-chain SFPs) were identified to contribute to the diffuse release of long-chain perfluoroalkyl acids (PFAAs) to the environment.
