    Sammanfattning : Anaerobic digestion and the production of biogas can provide an efficient means of meeting several objectives concerning energy, environmental and waste management policy. Interest in biogas is increasing, and new facilities are being built. LÄS MER

  2. 2. Exploring Impacts of Secondary Information Use on Individual Privacy

    Författare :Ali Padyab; Anna Ståhlbröst; Magnus Bergquist; Luleå tekniska universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; NATURVETENSKAP; SAMHÄLLSVETENSKAP; NATURAL SCIENCES; SOCIAL SCIENCES; Information systems; Informationssystem;

    Sammanfattning : Information collected from individuals via online social networks and Internet of things devices can be used by institutions and service providers for different business purposes to tailor and customize their services, which is defined as secondary use of information. Although the literature on secondary use is well developed, prior studies have largely focused on direct use of information such as those instances of information use that do not stem from data mining.

  3. 3. Search Processes, User Behaviour and Archival Representational Systems

    Författare :Anneli Sundqvist; Karen Anderson; Viveca Asproth; Thomas C. Nesmith; Mittuniversitetet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; access; activity theory; information behaviour; records; representation; users; handlingar; användare; informationsbeteende; tillgänglighet; aktivitetsteori; representationer; Computer and systems science; Data- och systemvetenskap;

    Sammanfattning : Information technology and political motives, e.g. e-governance, freedom of information legislation, has recent years lead to an increasing emphasis on users and access to records, but little research based knowledge about those issues exist so far. The main focus of the previous research is the use of non-current records in archival repositories. LÄS MER

  4. 4. Considering external costs : Their influence on technical measures in energy systems

    Författare :Annelie Carlson; Christian Azar; Linköpings universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : It is well known that conversion of energy gives rise to several environmental problems. The impact on the environment and human health can involve substantial indirect costs for society. These indirect costs are also known as external costs, since the market often does not consider them. LÄS MER

  5. 5. Energy Usage in Supermarkets - Modelling and Field Measurements

    Författare :Jaime Arias; Per Lundqvist; Denis Clodic; KTH; []
    Nyckelord :Supermarket; Energy Performance; System Analysis; Modelling; Simulation; Field Measurements; Refrigeration Systems; Indirect Systems; Heat Recovery; Floating Condensing; TEWI; LCC.; NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : This thesis investigates a special type of energy system, namely energy use in supermarkets through modelling, simulations and field studies. A user-friendly computer program, CyberMart, which calculates the total energy performance of a supermarket, is presented. LÄS MER
