1. 16. Elektrifiering av lastbilsflotta : Fallstudie på Akka Frakt

   Kandidat-uppsats, Uppsala universitet/Institutionen för samhällsbyggnad och industriell teknik

   Författare :Emma Löfgren Wallén; Emad Khalil Soliman Zaid; [2023]
   Nyckelord :biogas; conversion plan; electric truck; electrify truck fleet; environmental product declaration; HVO 100; life cycle; sustainable development; biogas; elektrifiera lastbilsflotta; ellastbil; HVO 100; hållbar utveckling; livscykel; miljövarudeklaration; omställningsplan;

   Sammanfattning : Introduction: The case study was conducted at the transport company Akka Frakt which faces the challenge of electrifying its vehicle fleet. The purpose of the study is to investigate how Akka Frakt can implement the conversion with as little impact as possible on the environment and operational activities. LÄS MER

3. 17. Investigation of MIDEL 7131’s Dielectric Breakdown Strength and Thermal Behaviour : Master Thesis, an experimental study using concentric-like electrodes at elevated temperatures to study breakdowns

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Kim Lin; [2023]
   Nyckelord :Dielectric strength; High voltage; Liquid dielectric; MIDEL 7131; Electrical breakdown; Temperature cycle; Dielektrisk styrka; Högspänning; Dielektriska vätskor; MIDEL 7131; Elektrisk nedbrytning; Temperaturcykling;

   Sammanfattning : Dielectric insulation are constantly exposed to various stresses, while also being expected to last for long periods of time. Naturally, they degrade with use and in demanding operational environments, this degradation phenomena can be accelerated, leading to costly consequences. LÄS MER

4. 18. Fabrication of sub-10 nm solid-state nanopores by electrical breakdown

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Kasumi Tsutsumi; [2023]
   Nyckelord :Nanopore fabrication; Solid-state material; Silicon nitride; Graphene; DNA translocation; Nanopor-avkänning; fast tillståndsmaterial; kiselnitrid; grafen; DNA-translokation;

   Sammanfattning : Nanopore sensing is a versatile technique that employs very small openings, known as nanopores, to study biomolecules. The use of nanopores on solid-state membranes has gained attention due to its potential for low-cost and high-throughput sensing of single molecules in liquids. LÄS MER

5. 19. Exploring the Potential of the Metaverse in Operations Management: Towards Sustainable Practices

   Master-uppsats, Jönköping University/JTH, Logistik och verksamhetsledning

   Författare :Yaroslav Ukhanov; Andreas Berggren; [2023]
   Nyckelord :Metaverse; Virtual reality; Operations management; Sustainable development;

   Sammanfattning : Problem statement - While reading earlier conducted research on how the Metaverse can be adopted into organizations' operations, a knowledge gap was identified. It was observed that despite the hype around the Metaverse, there is no empirical research on how organizations can adopt the Metaverse into their operations and how this can influence sustainable development.

7. 20. Control of distributed energy storage and EVs in building communities

   Magister-uppsats, Högskolan Dalarna/Institutionen för information och teknik

   Författare :Kweku Zigga; Usman Nasir; [2023]
   Nyckelord :Distributed energy storage systems DESS ; Electric Vehicles EVS ; Non coordinated control approach; Top-down control approaches; Bottom-up control approach; Renewable energy;

   Sammanfattning : This study delves into the comparative operational effectiveness of non-coordinated, bottom-up, and top-down coordinated control models within Distributed Energy Storage Systems (DESS) and Electric Vehicle (EV) networks. Employing meticulous data analysis, this research evaluates power demand and supply dynamics within the infrastructure and buildings, aiming to optimize energy usage and storage. LÄS MER
