  2. 1. Power Estimation for Indoor Light Energy Harvesting

    Author : Xinyu Ma; Bengt Oelmann; Sebastian Bader; Alex Weddell; Mittuniversitetet; []
    Keywords : ;

    Abstract : The growing popularity of indoor light energy harvesting for wireless sensor systems and low-power electronics has created a demand for systematic power estimation methods for different lighting conditions. Although existing research has recognized the critical role played by the spectral information on the output power of a photovoltaic cell, power estimation methods have rarely considered it.

  4. 2. Slag Formation During Pilot-Scale Pressurised Entrained-Flow Gasification of Woody Biomass

    Author : Charlie Ma; Christoffer Boman; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Abstract : Pressurised entrained‐flow gasification (PEFG) of sustainable woody biomass offers the opportunity for envi-ronmentally benign production of syngas that is suitable for synthesis of fuels and other chemicals. During the PEFG process, ash-forming matter in the fuel undergoes transformations. READ MORE

  5. 3. Experimental studies on treatment and recycling of pickling sludge generated in stainless steel production

    Author : Ping Ma; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

    Abstract : Pickling sludge generated in the stainless steel industries contains large amounts of calcium fluoride and water and relatively small amounts of metals. Therefore, such sludge is difficult to be directly recycled back to the EAF process and would be harmful to the environment if deposited as landfill for a long term. READ MORE

  6. 4. Development of low-cost ionic liquids based technology for CO2 separation

    Author : Chunyan Ma; Xiaoyan Ji; Päivi Mäki-Arvela; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Engineering;

    Abstract : CO2 separation plays an important role to mitigate the CO2 emissions due to burning of fossil fuels, and it is also of importance in biofuel production (e.g. biogas upgrading and bio-syngas purification and conditioning). The solvent-based absorption is the state-of-art technology for CO2 separation, where various solvents, e. READ MORE

  7. 5. Integration of engineering analysis information in the product development process

    Author : Ma Haoxue; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

    Abstract : Keen competition in modern industry motivates companies to produce better products in shorter lead-time. In addition low cost is another key factor that leads commercial success of a product. In the last decade, rapid development and implementation of computer technologies have had great impact on the product development process. READ MORE
