    Abstract : Ökat intresse för energiförbrukning och samtidiga krav på godtagbar termisk miljö gör det nödvändigt att i förväg kunna bedöma personpåverkan från olika kombinationer av klimatfaktorer. Enbart temperaturmätningar tar inte hänsyn till alla klimateffekter på en människa och speciellt inte för lokala effekter av luftrörelser och strålning. READ MORE

  3. 3. Footwear for cold environments. Thermal properties, performance and testing

    University dissertation from Luleå University of Technology, Dept. of Human Work Sciences, Div. of Industrial Ergonomics / Arbetslivsinstitutet, Programme for Respiratory Health and Climate

    Abstract : Abstract in Uncoded languages Praegune kaitsejalatsite testimise standard (EN 344) kontrollib soojapidavuslikke omadusi vaid jalatsi ühes punktis, mõõtes temperatuuri muutust. Meetod, mis kasutab termilist jala mudelit, võimaldab mõõta jalatsi soojaisolatsiooni üheaegselt erinevates piirkondades ning ühtlasi ka jalatsi kui terviku soojaisolatsiooni. READ MORE

  4. 4. Dynamic Solid Oxide Fuel Cell Modelling for Non-steady State Simulation of System Applications

    University dissertation from Faculty of Engineering, LTH Department of Energy Sciences Division of Thermal Power Engineering
