1. 1. Tradeoff Analysis and Sharding of Blockchain Technology

   Författare :Ahmed Afif Monrat; Olov Schelén; Karl Andersson; Stefanie Roos; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Blockchain; tradeoff; sharding; Pervasive Mobile Computing; Distribuerade datorsystem;

   Sammanfattning : Blockchain is a secured, shared, and distributed ledger system that records and tracks resources without requiring a centrally trusted authority. In addition to cryptocurrency, blockchain can be used for supply chain, logistics, healthcare, energy industries, and other financial services. LÄS MER

3. 2. Tradeoffs between self and environment in environmental judgment and decision making

   Författare :Hanna Andersson; Patrik Sörqvist; Ulla Ahonen-Jonnarth; Fredrik Bökman; Marita Wallhagen; Lars-Olof Johansson; Högskolan i Gävle; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; tradeoff; environmental concern; anchoring effect; normative message; travel time; avvägning; miljöoro; förankringseffekt; normativt budskap; restid; Hållbar stadsutveckling; Sustainable Urban Development;

   Sammanfattning : One of the greatest challenges of today is to change our behavior to act more pro-environmentally to reduce global warming. We need to make sacrifices for the environment, e.g., use a means of transportation that take a longer time but causes less CO2 emission. LÄS MER

4. 3. Tradeoff Analysis and Applications of Blockchain Technology

   Författare :Ahmed Afif Monrat; Olov Schelén; Karl Andersson; Juho Lindman; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Pervasive Mobile Computing; Distribuerade datorsystem;

   Sammanfattning : Traditional financial systems are based on trust in central authorities for secure transactions between parties. Blockchain on the other hand is a distributed ledger technology that stores data in a peer-to-peer decentralized network, where users can transfer money to each other without relying on centralized trusted intermediaries.

5. 4. Towards strategic development of maintenance and its effects on production performance : A hybrid simulation-based optimization framework

   Författare :Gary Linnéusson; Amos H. C. Ng; Tehseen Aslam; Daniel Tesfamariam Semere; Högskolan i Skövde; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strategic development; maintenance behavior; maintenance management; sustainable change; tradeoff optimization; system dynamics; discrete event simulation; problem structuring; multi-objective optimization; decision support; Production and Automation Engineering; Produktion och automatiseringsteknik;

   Sammanfattning : Managing maintenance in manufacturing within an economical short-termism framework and taking the consequential long-term cost effects into account is hard. The increasing complexity of managing maintenance and its impact on the business results calls for more advanced methods to support long-term development through effective activities in the production system environment.

7. 5. Limited Feedback Information in Wireless Communications : Transmission Schemes and Performance Bounds

   Författare :Thanh Tùng Kim; Mikael Skoglund; Hesham El Gamal; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diversity-multiplexing tradeoff; Large deviation analysis; Limited feedback; MIMO channels; Relay channels; Telecommunication; Telekommunikation;

   Sammanfattning : This thesis studies some fundamental aspects of wireless systems with partial channel state information at the transmitter (CSIT), with a special emphasis on the high signal-to-noise ratio (SNR) regime. The first contribution is a study on multi-layer variable-rate communication systems with quantized feedback, where the expected rate is chosen as the performance measure. LÄS MER
