1. 1. Comparative Analysis of In-Body to Out-Body Wireless CommunicationModules: Test Design and PerformanceEvaluation

   Master-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

   Författare :Remya Sree Rema Bhai; Sisymol Stellus; [2024]
   Nyckelord :In-Body to Off-Body Communication; prototype; test-design; test protocol; medical device; wireless communication.;

   Sammanfattning : Wireless communication for biomedical equipment is rapidly improving with the invention of new technologies. Due to the absence of cables, wireless technology is a growing area of interest for biomedical applications. As technology advances, many gadgets are becoming smaller and more portable. LÄS MER

3. 2. Local voltage control in a low voltage grid with high photovoltaic penetration

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

   Författare :Joakim Bakklund; [2024]
   Nyckelord :Technology and Engineering;

   Sammanfattning : This thesis examines how active power control (Volt-Watt control) and reactive power compensation (Volt-VAr control) can help limit voltage increases on the low voltage grid due to high photovoltaic (PV), installations. Due to the large increase in interest to install small scale PV-systems within residential areas the Distribution System Operator E. LÄS MER

4. 3. Framtidens lågspänningsnät : Analys av utmaningar och lösningar med ny teknik i nätet

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

   Författare :Oscar Dellham; [2023]
   Nyckelord :lågspänningsnät; flexibilitetstjänster; nätförstärkning; elbilsladdare; solceller; lastprognostisering;

   Sammanfattning : With an ever growing demand for electricity, it is tough to know which challenges will be the most pressing and which solutions will be appropriate to implement in different cases. This thesis utilizes simulations of three low voltage grids to see which part of the grid is most vulnerable, to which extent grid reinforcement is needed to solve voltage and load problems, and what amount of demand flexibility services would be an adequate substitute to grid reinforcement.

5. 4. Standardized Test Methods in Over-the-Air Chambers for FCC Part 27

   Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

   Författare :Oskar Hellström; [2023]
   Nyckelord :;

   Sammanfattning : Base stations (BSs) are the cornerstone that enables wireless communications. In order for a new BS variant to be imported and sold in the US they are required to undergo electromagnetic compatibility (EMC) testing. This testing is necessary to obtain their Federal Communications Commission (FCC) certification. LÄS MER

7. 5. Tillståndsprocessen för havsbaserad vindkraft - en flaskhals som hindrar utbyggnaden av förnybaraenergikällor?

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Juridiska institutionen

   Författare :Emma Söderlind; [2023]
   Nyckelord :Havsbaserad vindkraft; tillståndprocess; miljöprövning; förnybar energi;

   Sammanfattning : In light of the energy crisis and the aim to invest in renewable energy, offshore wind power has received an increased attention. The elevated status of investments in offshore wind has pointed out the problems with the legal process, which so far hasn’t - at least not in the case of establishment outside Swedish territory - been applied to aparticularly large extent.
