  1. 1. Indirect System Identification for Unknown Input Problems With Applications to Ships

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Jonas Linder; Linköpings universitet.; Linköpings universitet.; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System identification; Model structure; Unknown inputs; Indirect input measurements; Physical models; Instrumental variable; Closed loop; Graybox model; Identifiability; Ship; Marine vessel; Operational safety; Inertial measurement unit;

    Sammanfattning : System identification is used in engineering sciences to build mathematical models from data. A common issue in system identification problems is that the true inputs to the system are not fully known. In this thesis, existing approaches to unknown input problems are classified and some of their properties are analyzed. LÄS MER

  2. 2. Carbon Dioxide in Supermarket Refrigeration

    Detta är en avhandling från Stockholm : KTH

    Författare :Samer Sawalha; KTH.; [2008]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CO2; carbon dioxide; refrigeration system; supermarket; cascade; indirect; trans-critical; modelling; simulation; experiment; safety analysis; comparison; TECHNOLOGY Engineering mechanics Mechanical and thermal engineering Mechanical energy engineering; TEKNIKVETENSKAP Teknisk mekanik Mekanisk och termisk energiteknik Mekanisk energiteknik;

    Sammanfattning : This thesis theoretically and experimentally investigates different aspects of the application of CO2 in supermarket refrigeration. Theoretical analysis has been performed using computer simulation models developed to simulate CO2 indirect, NH3/CO2 cascade, CO2 trans-critical and direct expansion (DX) R404A systems. LÄS MER

  3. 3. System-Level Analysis and Design under Uncertainty

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Ivan Ukhov; Linköpings universitet.; Linköpings universitet.; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : One major problem for the designer of electronic systems is the presence of uncertainty, which is due to phenomena such as process and workload variation. Very often, uncertainty is inherent and inevitable. If ignored, it can lead to degradation of the quality of service in the best case and to severe faults or burnt silicon in the worst case. LÄS MER

  4. 4. Load Shifting and Storage of Cooling Energy through Ice Bank or Ice Slurry Systems modelling and experimental analysis

    Detta är en avhandling från Stockholm : KTH

    Sammanfattning : Ice based Cool Thermal Energy Storage (CTES) systems have attracted much attention during last few decades. The reasons are mainly of economical and environmental nature. LÄS MER

  5. 5. Indirect Exploitation of Intellectual Property Rights By Corporations and Investors: IP Privateering & Modern Letters of Marque & Reprisal

    Detta är en avhandling från Stockholm : KTH

    Författare :Thomas L Ewing; [2011]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; patent troll; indirect exploitation; patent; innovation system; intellectual property right IPR ; antitrust; privateer; patent misuse; equity; competition; corporate formalism; Intellectual property IP ; tortious interference; operating company; non-practicing entity NPE ; investor; unclean hands;

    Sammanfattning : Competitive pressures and rent-seeking behaviors have motivated companies and investors to develop indirect techniques for beneficially exploiting third-party intellectual property rights (IPRs) that qualitatively depart from the slate of direct exploitation tools whose usage has been honed during the past 30 years of the pro-patent era. Companies have increasingly realized that they do not need to create IPRs themselves to exploit them beneficially, which has been the conventional usage pattern. LÄS MER
