  1. 6. Free cooling in commercial buildings. Application with evaporative cooling tower and chilled beams

    Författare :Bengt Bergsten; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cooling tower; commercial buildings; simulation; low energy cooling; evaporative cooling; hydronic cooling system; internal heat gain; free cooling; chilled beams; methodology;

    Sammanfattning : The use of electricity in commercial buildings has increased over the last decades. One major cause is the rapid escalation of air conditioning equipment together with a growth of internal heat gains originating mainly from an increased amount of office equipment, which also use electric energy, and high levels of solar irradiation.

  4. 8. Inside the Ivory Tower- Inventors and Patents at Lund University

    Författare :Devrim Göktepe-Hultén; CIRCLE; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; patents; academic entrepreneurship; incentives; university inventors; intellectual property rights; Bayh-Dole Act; technology transfer; TTOs; Teacher s exception;

    Sammanfattning : The purpose of this thesis is to identify patents invented by researchers at Lund University, to describe the university inventors,and to understand the main factors that influence their patenting activities. The analysis focuses on inventors in relation to their environment. A number of factors influence scientists’ decisions to patent. LÄS MER

  5. 9. VLSI aspects on inversion in finite fields

    Författare :Mikael Olofsson; Christof Paar; Linköpings universitet; []
    Nyckelord :VLSI; Inversion; Finite Fields; Area; Delay; Power dissipation; Irreducible polynomials; Polynomial basis; Triangular basis; Normal basis; Dual basis; Tower fields.; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Different algorithms and architectures for inversion in finite extension fields are studied. The investigation is restricted to fields of characteristic two. Based on a simple transistor model, various architectures are compared with respect to delay, area requirement, and energy consumption. LÄS MER

  7. 10. POSITION MOORING OF WAVE ENERGY CONVERTERS - An engineering study into the mooring of structures in a highly exposed shallow ocean regime, within the context of the economics of renewable energy conversion

    Författare :John Fitzgerald; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; energy; catenary; articulated tower; ocean; Mooring; wave; anchor; energy;

    Sammanfattning : The principles of systems engineering are applied in order to establish the requirements formooring wave energy conversion devices. These requirements capture both the function ofmaintaining position in energetic wave climates as well as the need to enable an economiclifecycle for the development of a viable wave energy conversion industry.
