  1. 1. Hydrogen storage systems : Methodology and model development for hydrogen storage systems performance evaluation based on a transient thermodynamic approach

    University essay from Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Author : Kreshnik Margaritari; [2023]
    Keywords : Hydrogen; Hydrogen storage system; Hydrogen filling process; Hydrogen storage system operation; Hydrogen storage system design; Hydrogen fast filling; Hydrogen tank modelling;

    Abstract : The overall performance of a hydrogen storage system can be affected by various parameters, such as operation and design parameters, but also by the state of the hydrogen contained inside the storage tanks. In this work, a methodology is developed to evaluate the state of the hydrogen during the filling process and its impact on the overall system performance under variable operation conditions and design parameters.

  3. 2. Empirical Evaluation of Construction Methods for Relaxed Decision Diagrams in Scheduling

    University essay from Linköpings universitet/Programvara och system

    Author : Dennis Berntsson; [2023]
    Keywords : Decision diagrams; Discrete optimization; Dynamic programming; Scheduling; Top-down compilation; Incremental refinement;

    Abstract : Decision diagrams have recently emerged as a promising approach for difficult scheduling problems, along with other challenging discrete optimization problems. Decision diagrams can offer a compact representation of the solution space, and has the ability to capture complex constraints that are hard to model or express in other techniques. READ MORE

  4. 3. A Bayesian Bee Colony Algorithm for Hyperparameter Tuning of Stochastic SNNs : A design, development, and proposal of a stochastic spiking neural network and associated tuner

    University essay from Uppsala universitet/Signaler och system

    Author : Oskar Falkeström; [2023]
    Keywords : edge computing; edge user allocation; constraint satisfaction problem; bin packing problem; spiking neural networks; SNN; stochastic spiking neural networks; neuromorphic computing; hyperparameter tuning; swarm intellience; artificial bee colony algorithm; tree-structured Parzen estimator; stochastic optimization; Bayesian optimization.;

    Abstract : With the world experiencing a rapid increase in the number of cloud devices, continuing to ensure high-quality connections requires a reimagining of cloud. One proponent, edge computing, consists of many distributed and close-to-consumer edge servers that are hired by the service providers. READ MORE

  5. 4. Comparing Quantum Annealing and Simulated Annealing when Solving the Graph Coloring Problem

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Nora Odelius; Isak Reinholdsson; [2023]
    Keywords : Quantum Computing; Quantum Annealing; Simulated Annealing; Graph Coloring Problem; Kvantberäkningar; Quantum Annealing; Simulated Annealing; Graffärgningsproblemet;

    Abstract : Quantum annealing (QA) is an optimization process in quantum computing similar to the probabilistic metaheuristic simulated annealing (SA). The QA process involves encoding an optimization problem into an energy landscape, which it then traverses in search for the point of minimal energy representing the global optimal state. READ MORE

  6. 5. Simulering av effektbehovet på industrier och terminaler vid elektrifiering av skogstransporter

    University essay from SLU/Dept. of Energy and Technology

    Author : Albin Werre; [2023]
    Keywords : laddinfrastruktur; effektbehov; skogstransporter; elektromobilitet;

    Abstract : In this study a discrete event-based simulation approach is used to quantify and evaluate the power need from fast charging of an electrified Swedish forest transport fleet. The simulation is done on three locations which where evaluated as likely locations of charging infrastructure, two pulp industries as well as one terminal. READ MORE
