1. Minimera felaktiga produktförsändelser medhjälp av lean-metoder och standardisering : Minimize incorrect product shipments using lean methods and standardization
Uppsats för yrkesexamina på grundnivå, Örebro universitet/Institutionen för naturvetenskap och teknikSammanfattning : Detta examensarbete har utförts på Epiroc DC Holmen som är ett globalt distributionscenterbeläget i Örebro. En hög kvalitetsnivå kan leda till kostnadsbesparingar genom att antaletavvikelser minskar. På DC Holmen, där höga kostnader uppstår på grund avkvalitetsavvikelser vid hantering av tungt gods, är detta av särskilt intresse. LÄS MER
2. Data Centres as Prosumers: A Techno-Economic Analysis
Master-uppsats, Uppsala universitet/Institutionen för materialvetenskapSammanfattning : Rapid growth of digitalization has urged Data Centres (DC) to be more energy efficient by recovering waste heat from server racks that would otherwise be wasted. This techno-economic study is focused on upgrading low temperature waste heat from typical Air-Cooled DC for District Heating Network (DHN) market in Stockholm region. LÄS MER
3. Evaluation of the challenges and opportunities of Vehicle-to-Grid technology and the potential revenue streams for BEV fleet owners and aggregators
Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : The increasing amount of renewable energy being connected to the power grid, and the intermittent nature of these resources, calls for increased grid flexibility to ensure operational safety and stability. An effective solution to address this need could be through wider implementation of various energy storage technologies. LÄS MER
4. Reliability and Cost-Benefit Analysis of the Battery Energy Storage System
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : The battery energy storage system (BESS) is crucial for the energy transition and decarbonisation of the energy sector. However, reliability assessment and capital cost challenges can hinder their widespread deployment. LÄS MER
5. Extending Wireless Power Transfer Range for Self-Powered Micro Devices with mm-size Antenna
Master-uppsats, Linköpings universitet/Elektroniska Kretsar och SystemSammanfattning : The primary challenge in expanding the wireless power transfer range for miniaturized self-powered micro devices is the limited RF energy harvesting due to the small effective area and low gain of the mm-sized antennas used in these devices. This thesis introduces a method for extending the distance between an external energy source antenna (TX) and a micro-device antenna (RX) to more than 10 cm. LÄS MER
