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

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Jonas Linder; Martin Enqvist; Fredrik Gustafsson; Alexandre Sanfelice Bazanella; [2017]
    Keywords : 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;

    Abstract : 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. READ MORE

  2. 2. Carbon Dioxide in Supermarket Refrigeration

    University dissertation from Stockholm : KTH

    Author : Samer Sawalha; Björn Palm; Eckhard Groll; [2008]
    Keywords : 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;

    Abstract : 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. READ MORE

    University dissertation from Stockholm : KTH

    Author : Marino Grozdek; Per Gunnar Lundqvist; Michael Kauffeld; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; refrigeration systems; cool thermal energy storage system; ice; modelling; simulation; field measurement; experiment; indirect system; ice-on-coil system; external melt; ice slurry; homogeneous storage; heterogeneous storage; TECHNOLOGY Engineering mechanics Mechanical and thermal engineering Thermal energy engineering; TEKNIKVETENSKAP Teknisk mekanik Mekanisk och termisk energiteknik Termisk energiteknik;

    Abstract : 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. READ MORE

  4. 4. System Expansion and Allocation in Life Cycle Assessment With Implications for Wastepaper Management

    University dissertation from Stockholm : KTH

    Author : Tomas Ekvall; [1999]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; allocation; system expansion; LCI methodology; waste incineration; waste management; system boundaries; life cycle inventory analysis; paper recycling; environmental life cycle assessment; modelling;

    Abstract : The choice of system boundaries and allocation methods can have decisive effects on the results and conclusions of a life cycle assessment (LCA). System expansion makes it possible to model the indirect effects of a decision; however, this modelling is often based on inaccurate assumptions. READ MORE

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

    University dissertation from Stockholm : KTH

    Author : Thomas L Ewing; [2011]
    Keywords : 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;

    Abstract : 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. READ MORE
