  1. 1. VAM Cluster Optimization

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi

    Author : Eric Sjöström; [2023]
    Keywords : Traffic-Safety; Clustering; Vulnerable-Road-Users; ETSI; Intelligent-Transport-System; V2X; Trafik-Säkerhet; Klustring; Oskyddade-Trafikanter; ETSI; Intelligent-Transport-System; V2X;

    Abstract : This thesis will research and evaluate the state of the current ETSI VAM standard. The thesis evaluates and discusses the means of improving the speed and response of ETSI VAM by reducing the load on the radio medium. The research looks to prove that fewer messages broadcasted improve VRU awareness. READ MORE

  3. 2. Hardware-in-the-loop Simulation of a Pumping Station : Design and implementation of a Python-based simulation program

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

    Author : Katrina Liang; [2022]
    Keywords : Hardware-in-the-loop simulation; Simulation; Modeling; Pumping stations; Pump controller; Hardware-in-the-loop simulering; Simulering; Modellering; Pumpstationer; Pumpstyrning;

    Abstract : The use of simulation enables testing of a system without the need for a complete physical system, while also having the advantages of lower cost and fewer practical limits compared to field tests. Hardware may be integrated into the simulation loop, such a simulation is defined as a Hardware-in-the-loop (HIL) simulation. READ MORE

  4. 3. PCBA verification and fault detection using a low-frequency GMR-based near-field probe with magnetic closed-loop feedback compensation : A non-contact alternative to physical probing

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

    Author : Joacim Sundh; [2022]
    Keywords : GMR; sensor; magnetic field; near-field; probe; linearity; PCB; coil; PCBA; analogue integrated circuits; analog; operational amplifiers; electrical fault detection; feedback circuits; in-circuit tests; GMR; sensor; magnetfält; närfält; sond; linjäritet; mönsterkort; spole; kretskort; analoga integrerade kretsar; operationsförstärkare; elektrisk feldetektering; återkopplingskretsar; kretskortstest;

    Abstract : As electronics are getting both smaller and more advanced, the need to verify and validate remains and the means are getting more complex the more functions and components are added. Traditionally, in-circuit tests (ICTs) are performed by probing dedicated test points on the Printed Circuit Board Assembly (PCBA) in a test sequence that is unique to each product. READ MORE

  5. 4. Development of GNSS Type Processing for the Characterization of the Mobile Propagation Channel

    University essay from KTH/Fastigheter och byggande

    Author : Adrien Bardou; [2021]
    Keywords : LMS Channel; Multi-paths; GNSS; SCHUN; Simulation; LMS-kanal; flerv¨agar; GNSS; SCHUN; Simulering;

    Abstract : Mobile communication systems are undergoing significant development on increasingly wide frequency bands (5G in particular). To support this development, a detailed characterization of the propagation of electromagnetic waves in L, S and C band between a station (satellite, airborne or ground) and a mobile platform is necessary to analyze and model the phenomena that have a decisive impact on the performance, availability and operability of systems.

  6. 5. Freedom To Originate - Developing Fin Plug and Fins for Jetboards

    University essay from Lunds universitet/Innovation

    Author : Albin Johnsson Jähnke; Alex Mauritzson; [2021]
    Keywords : Fin plug; fins; jetboard; CFD; user testing; concept generation; Technology and Engineering;

    Abstract : This master thesis generates a concept for the means of attaching fins onto jetboards without infringing on existing patents. The resulting concept establishes freedom to operate (FTO) and enables production of fins with original designs. FTO meaning the possibility of producing and selling a product without legal liability to any patent holders. READ MORE
