    Abstract : With joint commitments by twenty-seven countries under the Paris Agreement, the European Union envisioned a resource-efficient and competitive economy without net emission of greenhouse gases by 2050. Immediate and massive efforts across sectors of energy, industry, and buildings will be required, and district heating (DH), through its ability to integrate efficiency measures on the supply and demand side, can play a central role.

  5. 3. Enterprise Systems Modifiability Analysis : An Enterprise Architecture Modeling Approach for Decision Making

    Author : Robert Lagerström; Pontus Johnson; Marc Lankhorst; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Enterprise Architecture; Software System Modifiability; Decision Making; Metamodeling; Enterprise Architecture Analysis; Software Change Cost Estimation; Other information technology; Övrig informationsteknik;

    Abstract : Contemporary enterprises depend to great extent on software systems. During the past decades the number of systems has been constantly increasing and these systems have become more integrated with one another. This has lead to a growing complexity in managing software systems and their environment. READ MORE

  6. 4. Enterprise Architecture for Information System Analysis : Modeling and assessing data accuracy, availability, performance and application usage

    Author : Närman Per; Mathias Ekstedt; Pontus Johnson; Sjaak Brinkkemper; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Enterprise Architecture; Metamodeling; Decision-making; Data Accuracy; Service Availability; Service Performance; Technology Acceptance Model; Task Technology Fit;

    Abstract : Decisions concerning IT systems are often made without adequate decision-support. This has led to unnecessary IT costs and failures to realize business benefits. The present thesis presents a framework for analysis of four information systems properties relevant to IT decision-making. READ MORE

  7. 5. A methodology for situated and effective design of haptic devices

    Author : Xuan Sun; Kjell Andersson; Ulf Sellgren; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Design optimization; haptic devices; metamodel; multi-criteria; situatedness; Machine Design; Maskinkonstruktion;

    Abstract : The realism of virtual surgery through a surgical simulator depends largely on the precision and reliability of the haptic device. The quality of perception depends on the design of the haptic device, which presents a complex design task due to the multi-criteria and conflicting character of the functional and performance requirements.
