  1. 41. Värmestress i sen dräktighet och dess påverkan på mjölkproduktion, fertilitet och hälsa

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Anna Karlstrand; [2022]
    Keywords : värmestress; mjölkkor; sen dräktighet; mjölkproduktion; mjölkavkastning; fertilitet; djurhälsa;

    Abstract : Klimatförändringarna resulterar i allt högre omgivningstemperaturer som i framtiden beräknas stiga ytterligare. Detta utgör en risk för livsmedelssektorn eftersom allt fler värmeböljor är beräknade, vilka kan komma att resultera i alltmer värmestress. READ MORE

  3. 42. Design and evaluation of ambient RF energy harvesting platform for sensor-based systems : An experimental study of RF energy harvesting

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Ibrahim Hamed; [2022]
    Keywords : Radiofrekvensenergiskördning; Trådlös energiskördning; Backscattering-teknik; Programvarudefinierad radio; EMC; PCB; Antenn;

    Abstract : Trådlös energiskörd möjliggör förmågan att skörda energi från elektromagnetisk strålning. Med de senaste framstegen inom trådlös kommunikationsteknik och med tillgången till energieffektiva sensorer, så har radiofrekvensenergiskördning potential till att bli en självförsörjande sensorbaserad plattform.

  4. 43. Development of heat recovery solution for heavy duty truck cabs to improve energy efficiency.

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Exekiel Aurelio; Rahul Acharya Rathnakar; [2022]
    Keywords : air-to-air heat recovery; air-to-liquid heat recovery; integrated thermal management system; heat wheel; heat pump; battery electric vehicle; battery electric trucks; energy savings.; luft-till-luft värmeåtervinning; luft-till-vätska värmeåtervinning; integrerat värmehanteringssystem; värmehjul; värmepump; batterielektriskt fordon; batterielektriska lastbilar; energibesparingar.;

    Abstract : The recent climate actions to reduce greenhouse gas (GHG) emissions have set the stage for decarbonizing the transportation sector through electrification, which has led to a surge in the deployment of battery electric vehicles (BEV). Trucks are no exception, which has led automakers to shift their focus toward producing Battery Electric Trucks (BET). READ MORE

  5. 44. Synthesis and thermoelectric properties of Cr1-xMexN (Me = Mo, V)

    University essay from Linköpings universitet/Tunnfilmsfysik

    Author : Victor Rutberg; [2022]
    Keywords : Chromium nitride; thin films; thermoelectrics; physical vapour deposition; medium entropy alloy;

    Abstract : Among emerging materials systems for thermoelectric applications, the early transition-metal nitrides based on ScN and CrN show unexpectedly promising properties. These properties are determined by high Seebeck coefficient, low thermal conductivity, and high electrical conductivity. READ MORE

  6. 45. Energy Usage in Railway Wayside Object Heating : Modeling of melting of Ice, Estimation of heating power requirement in Switch and Renewable energy feasibility for a Railway system

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Sidharth Kapoor; [2022]
    Keywords : Melting of Ice; Numerical modeling; Transient conjugate heat transfer; Transient analysis; CFD; Switch heating; Heat pumps in Railways; Issmältning; Numerisk modellering; Transient värmeöverföring; Transientanalys; CFD; Värmepumpar i järnvägar;

    Abstract : Trafikverket operates about 12000 Switches and crossings (SnCs) of which 6800 are equipped with an electrical heating system of 10−30kW power to keep SnCs functional throughout the winters by keeping them free of Snow/Ice. The energy consumption is approximately 200−130GWh/year costing approximately 10−15 million Euros annually. READ MORE
