    Sammanfattning : In the early days of gear manufacturing, engineers aimed to produce teeth as close to the theoretical shape as possible. As machinery advanced and demand for high-speed, high-torque, and quieter transmissions grew, optimizing gear teeth became increasingly important [1]. LÄS MER

    Sammanfattning : Sub-band full duplex is a new communication scheme technology, where a single frequency band is partitioned into sub-bands for downlink (DL) and up-link(UL) transmissions, and both can take place simultaneously. The idea behind the sub-band full duplex development is to improve the throughput, and coverage and reduce the latency of the UL communication by allowing the UL reception during the DL transmission.

    Sammanfattning : Energy Harvesting, also known as power harvesting or ambient power, is the process of obtaining small amounts of power from secondary sources, such as vibrations, light, temperature variations and even radio-frequency emissions. These systems have been uncommon in personal and wearable electronics in the past, however they are slowly gaining traction. LÄS MER

  5. 4. Energy System Analysis of thermal, hydrogen and battery storage in the energy system of Sweden in 2045

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Sammanfattning : Sweden has goals to reach net-zero emissions by 2045. Although electricity sector is almost fossil free, industry & transport still rely on fossil fuels. Ambitious initiatives such as HYBRIT, growth of EV market & expansion of wind power aim to expedite emission reduction. LÄS MER

  7. 5. Intelligent reflective vest with implementation of ETSI VAM protocol : Development and testing of an embedded system for the protection of Vulnerable Road Users

    Uppsats för yrkesexamina på avancerad nivå, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Linnéa Olsson; Markus Rydeberg; [2023]
    Nyckelord :;

    Sammanfattning : This master thesis presents a wearable, ETSI-compliant system for protecting Vulnerable Road Users (VRUs). The study explores the current ETSI VAM parameters, which are too similar to vehicle pa- rameters and may react differently to different types of VRUs, gen- erating an excessive or insufficient number of VAMs, and potentially jeopardizing VRU safety.
