1. Construction of a scanning confocal microscope for Quantum Dot mapping at telecom wavelength
Master-uppsats, KTH/Tillämpad fysikSammanfattning : Future commercial applications making use of non-classical light sources require bright quantum emitters. Such emitters can be achieved by embedding self-assembled, optically active semiconductor quantum dots (QDs) in centered photonic structures. LÄS MER
2. Optimization of Light Conditions in a Greenhouse Environment : Reducing energy consumption and increasing yield using mechatronics
Magister-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : The present thesis explores the possibilities of reducing electrical energy consumption in a greenhouse environment through the construction a demonstrator system. The demonstrator system is imagined to be used in a vertical farming setup and is fully automated. The system achieves two main actions. LÄS MER
3. Pre-study of optical LED units for shunting signals
M1-uppsats, KTH/Hälsoinformatik och logistikSammanfattning : Alstom wanted to investigate the possibility of adapting its light emitting diode (LED) technology for shunting signals in train traffic. The LED technology uses 50V, but Alstom wants to adapt it for 12V. The LED technology is energy efficient but needs to be adapted for existing signal interlocking by drawing a higher current. LÄS MER
4. Achieving Optimal Alignments of IR Source and Detector in Waveguide Based Gas Sensor
Uppsats för yrkesexamina på grundnivå, KTH/Medicinteknik och hälsosystemSammanfattning : I takt med att tekniken för mikroelektromekaniska system utvecklas uppkommer det nya områden för tillämpning. Ett område är inom gassensorer där icke-dispersiv infraröd strålning används genom att mäta absorptionen hos olika gaser för att bestämma mängden av en specifik gas i luften. LÄS MER
5. Best PAL : Ball Exercise Sound Tracking PAL
Kandidat-uppsats, KTH/Maskinkonstruktion (Inst.)Sammanfattning : The PAL (Practise and Learn) Original is a ball boardconsisting of three wooden boards placed in a triangle, developedto practise football players’ passing ability and firsttouch. The former Swedish international footballer JessicaLandstr¨om observed that these ball boards can, if they areimproved, help footballers to develop even more skills whilepracticing alone. LÄS MER
