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

   University essay from Linköpings universitet/Informationskodning

   Author : Oscar Pihl; [2023]
   Keywords : 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;

   Abstract : 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.

   Abstract : 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. Pre-study of optical LED units for shunting signals

   University essay from KTH/Hälsoinformatik och logistik

   Author : Tobias Adolfsson; Axel Dellenby; [2021]
   Keywords : LED - Light Emitting Diode; Booster Converter; MLCC - Multi-layer capacitor; ESR - Equivalent Serie Resistance; OU - Optical Unit; Reactive compensation; LED - lysdiod; step-up omvandlare; MLCC - flerskiktskeramisk kondensator; ESR - ekvivalent serie motstånd; OU - optiskt enhet; reaktiv kompensering;

   Abstract : 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.

5. 4. Image analysis for smart manufacturing

   University essay from Högskolan i Halmstad/Akademin för informationsteknologi

   Author : Felix Nilsson; [2019]
   Keywords : Stack lights; image analysis; industri 4.0; smart manufacturing;

   Abstract : The world of industrial manufacturing has changed a lot during the past decades. It has gone from a labour-intensive process of manual control of machines to a fully connected and automated process. The next big leap in industrial manufacturing is known as industry 4.0 or smart manufacturing. READ MORE

6. 5. Effectiveness of a speed advisory traffic signal system for Conventional and Automated vehicles in a smart city

   University essay from Linköpings universitet/Kommunikations- och transportsystem; Linköpings universitet/Tekniska fakulteten

   Author : Hossam Anany; [2019]
   Keywords : Traffic management; Micro simulation; Traffic flow efficiency Travel time - trip delay ; Green Light Optimal Speed Advisory GLOSA ; V2I communication; Conventional vehicles; connected vehicles; Automated vehicles; Mixed Traffic Environment; smart cities;

   Abstract : This thesis project presents a traffic micro simulation study that investigates the state-of-the-art in traffic management "Green Light Optimal Speed Advisory (GLOSA)" for vehicles in a smart city. GLOSA utilizes infrastructure and vehicles communication through using current signal plan settings and updated vehicular information in order to influence the intersection approach speeds. READ MORE
