    University essay from KTH/Skolan för teknik och hälsa (STH)

    Author : Vasileios Charalampidis; [2017]
    Keywords : cloud computing; sedentary behavior; prolonged sitting; android wear; smartwatch; android mobile; IBM Bluemix; Node-RED; gamification methods; freeboard; cloud computing; stillasittande beteende; långvarigt sittande; android wear; smartwatch; android mobile; IBM Bluemix; Node-RED; gamifieringsmetoder; freeboard;

    Abstract : Nowadays, prolonged sitting among office workers is a widespread problem, which is highly related to several health problems. Many proposals have been reported and evaluated to address this issue. However, motivating and engaging workers to change health behavior to a healthier working life is still a challenge. READ MORE

  3. 17. Impact of Converter Modulation Strategies on the Losses in a Traction Motor

    University essay from KTH/Elektrisk energiomvandling

    Author : Emil Fjällström; [2015]
    Keywords : Induction Machine; FEM; FLUX; Induktionsmotor; FEM; FLUX;

    Abstract : With an increased demand on high-efficiency electrical machines in traction applications, better understanding in the losses induced by the converter is needed. The harmonic losses from the converter are non-negligible part of the total losses in an induction machine, and these harmonic losses have been studied here with a focus on iron, skin-effect and proximity losses.

    Abstract : In recent decades, railway transport infrastructures have been regaining their importance due to their efficiency and environmentally friendly technologies. This has led to increasing train speeds, higher axle loads and more frequent train usage. READ MORE

  5. 19. Öresundsparken - ett pedagogiskt strandlaboratorium

    University essay from SLU/Landscape Architecture (until 121231)

    Author : Jenny Åkesson; [2011]
    Keywords : havsnivåhöjning; landskapsarkitektur; landskapslaboratorium; park; hållbar design;

    Abstract : Havsnivåhöjningen kommer innebära en förändring av kustlandskapet. Diskussionen om anpassningen till havsnivåhöjningen har hittills fokuserat på den bebyggda kusten. Höjda havsnivåer innebär ändrade förutsättningar även för den obebyggda kusten genom förändrade strandlinjer, fler och kraftigare översvämningar och ökad erosion. READ MORE

  6. 20. 3D parameterized FEM modelling of a piston ring in a marine diesel engine : a simulation approch using FEM

    University essay from Institutionen för fysik

    Author : Jon Elfridsson; [2010]
    Keywords : piston ring; finite element method; FEM; solid mechanics; contact pressure; twist; temperature field; three-dimensional; kolvring; finita elementmetoden; FEM; hållfasthetslära; kontakttryck; twist; värmelast; tredimensionell;

    Abstract : The piston ring in a marine two-stroke diesel engine operates in demanding conditions, involving high temperatures and pressures. Its main purposes are to seal the combustion chamber of the engine, minimize the frictional contact against the cylinder liner and transfer heat from the piston. READ MORE
