1. 1. Characterization and Stabilization of Transverse Spatial Modes of Light in Few-Mode Optical Fibers

   Master-uppsats, Linköpings universitet/Informationskodning

   Författare :Oscar Pihl; [2023]
   Nyckelord :spatial modes; Space division multiplexing; SDM; superpositions; LP-modes; few-mode fibers; quantum communication; quantum optics; adaptive optics; stochastic parallel gradient descent; SPGD; mode control; QKD; polarization controller; paddle controller; QRNG; quantum random number generator; spatial modes; perturbation effects;

   Sammanfattning : With the growing need for secure and high-capacity communications, innovative solutions are needed to meet the demands of tomorrow. One such innovation is to make use of the still unutilized spatial dimension of light in communications, which has promising applications in both enabling higher data traffic as well as the security protocols of the future in quantum communications.

   Sammanfattning : Is it possible to increase traffic flows and decrease stand stills in rush hour traffic by tweaking existing traffic light signals? A vehicle’s engine running on idle is not useful in physical terms and emits unnecessary exhausts. By investigating and observing signal phase times on site in Hangzhou, China, an effort was made to find out if it was possible to get better flow and thus lower emissions by changing the traffic signal programs.

4. 3. Utformning av cykeltrafikytor i signalreglerade korsningar : För ökad framkomlighet och trafiksäkerhet för cykeltrafiken i nordiska förhållanden

   Master-uppsats, KTH/Transportplanering

   Författare :Aleksi Kinnunen; [2022]
   Nyckelord :;

   Sammanfattning : Detta examensarbete avser att undersöka utformningslösningar för trafikljusstyrda korsningar utifrån cykeltrafikens perspektiv. Frågeställningen är att utreda vilka utformningselement kan observeras ha önskad effekt på cyklisters beteende vid signalkorsningar. LÄS MER

5. 4. Feldetektering i återgångkablar

   Kandidat-uppsats, Umeå universitet/Institutionen för tillämpad fysik och elektronik

   Författare :Erik Asp; [2021]
   Nyckelord :Feldetektering;

   Sammanfattning : The purpose of ths report is to shed light on the problems surrounding error detection in returncables, specifically in connection with tunnels. In Sweden, among other things, has chosen to usea BT system with a suction transformer and a dedicated return conductor to reduce interferencesuch as occurs on telecommunications and signal cables along the track.
