  1. 36. MODELLING OF HEAT TRANSFER OF RAILWAY SWITCH HEATING

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

    Author : Siddharth Suresh Sumathi; [2023]
    Keywords : Conjugate Heat transfer analysis; transient analysis; CFD; insulation; measurement data uncertainties.; Konjugat Värmeöverföringsanalys; transientanalys; CFD; isolering; mätdata osäkerheter.;

    Abstract : Switches and crossings are vital components of the railway network. Obstacles to the smooth functioning of these components could result in delays and network traffic. Given the geographical location of Sweden, snow is one of the major obstacles for the switches. READ MORE

  3. 37. Green Room : A climate controlling grow-box for growing mushrooms and greens.

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

    Author : Bill Skullman; Gabriella Herlin; [2023]
    Keywords : Mechatronics; Aeroponic farming; Mushroom farming; Photosynthesizing plants - Greens; Ultrasonic atomizer; Mekatronik; Aeroponisk odling; Svampodling; Fotosyntetiserande växter; Ultraljudsluftfuktare;

    Abstract : This report covers a project on a partially automated aeroponic and fungi growing system. The purpose is to evaluate if an enclosed space system can be automated to produce healthy crops of greens and fungi, and investigate how well the system can switch between these two growth modes.

  4. 38. The ecological impact of artificial light at night in landscape architecture : strategies and guidelines for street lights for the benefit of biodiversity and local wildlife

    University essay from SLU/Dept. of Urban and Rural Development

    Author : Zozan Altun; [2023]
    Keywords : light pollution; artificial light at night; ecology; biodiversity; local wildlife; landscape architecture; guidelines; strategies;

    Abstract : Artificial light at night (ALAN) is an increasingly common form of light pollution that contributes to biodiversity loss, loss of dark habitats, disrupting populations both on an individual- and population level by invading biodiversity hot spots. Recent studies show that artificial light is increasing at a rate of approximately 6% annually over Earth’s surface, and 88% of Europe and 47% of the United States experience light pollution on a nightly basis.

  5. 39. Spectral broadening of 4 mJ femtosecond pulses using a bulk multi-pass cell

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Saga Westerberg; [2023]
    Keywords : Lasers; Ultrashort; Nonlinear Optics; femtosecond; Multi-Pass Cell; Spectral broadening; pulse post-compression; Self phase modulation; Physics and Astronomy;

    Abstract : Nonlinear optical effects can be used for spectral broadening, which the basis of the field of post-compression of laser pulses. When the intensity of light becomes high enough the refractive index becomes intensity dependent, and as the intensity often varies both with position and time so does the refractive index.

  6. 40. Tracking Optimization in Agrivoltaic Systems : A Comparative Study for Apple Orchards

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

    Author : Maddalena Bruno; [2023]
    Keywords : Agrivoltaics; Optimization; Light sharing; Apple Orchards; Lantbruk; Optimering; Ljusdelning; Äppelodlingar;

    Abstract : Agrivoltaic (APV) systems, based on the co-location of solar panels and crops, are an innovative solution to land-use conflicts that often arise between agriculture and energy production. Their optimal functioning starts with efficient management and sharing of light between solar panels and underlying plants. READ MORE
