1. 1. Task Scheduling Using Discrete Particle Swarm Optimisation

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

   Författare :Hampus Karlberg; [2020]

   Sammanfattning : Optimising task allocation in networked systems helps in utilising available resources. When working with unstable and heterogeneous networks, task scheduling can be used to optimise task completion time, energy efficiency and system reliability. The dynamic nature of networks also means that the optimal schedule is subject to change over time. LÄS MER

   Sammanfattning : Control theory and its applications are crucial when operating within the area of dynamic systems. Compensating for disturbances and external actions imposed on a given system being inherently unstable or semi-stable. LÄS MER

4. 3. GDP Growth Rate Nowcasting and Forecasting

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

   Författare :Fredrik Björnfot; [2017]
   Nyckelord :;

   Sammanfattning : The main purpose of this project was to help Swedbank get a better understandingof how gross domestic product growth rate develops in the future froma data set of macroeconomic variables. Since GDP values are released long aftera quarter has ended Swedbank would like to have a model that could predictupcoming GDP from these data sets. LÄS MER

5. 4. Algorithmic Trading Based on Hidden Markov Models — Hidden Markov Models as a Forecasting Tool When Trying to Beat the Market

   Kandidat-uppsats, Göteborgs universitet/Företagsekonomiska institutionen

   Författare :Josephine Cuellar Andersson; Linus Fransson; [2016-06-29]

7. 5. Control of Leaning Dynamics for Three-wheeled Vehicles : Experimental evaluation of two control strategies

   Kandidat-uppsats, KTH/Maskinkonstruktion (Inst.)

   Författare :ROBERT GRÖNING; GUSTAV STEN; [2016]
   Nyckelord :;

   Sammanfattning : Three‐wheelers are popular in fuel efficient contests but do not see much commercial success. This could be because three‐wheelers are easier to tip over than four wheeled vehicles. One way to counteract the tipping over is to introduce leaning dynamics on three‐wheeled vehicles so that they lean in corners like bicycles and motorcycles can. LÄS MER
