  1. 1. Optimizing Resource Allocation in Kubernetes : A Hybrid Auto-Scaling Approach

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

    Author : Brando Chiminelli; [2023]
    Keywords : Cloud computing; Microservices; Kubernetes; Container Orchestration; Auto-Scaling; Horizontal Pod Autoscaler HPA ; WorkloadPrediction; Time-Series Forecasting; Molntjänster; Mikrotjänster; Kubernetes; Containerorkestrering; Automatisk Skalning; Horizontal Pod Autoscaler HPA ; Förutsägelse avArbetsbelastning; Prognoser för Tidsserier;

    Abstract : This thesis focuses on addressing the challenges of resource management in cloud environments, specifically in the context of running resource-optimized applications on Kubernetes. The scale and growth of cloud services, coupled with the dynamic nature of workloads, make it difficult to efficiently manage resources and control costs. READ MORE

  3. 2. Dynamic Control, Modeling and Sizing of Hybrid Power Plants : Investigating the optimum usage of energy storage for Fortum’s hydropower

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

    Author : Klas Lindgren; [2023]
    Keywords : Hydropower Plants; Energy Storage Systems; Hybrid Units; Frequency Regulation; Modeling; XGBoost Regression; Vattenkraftverk; Energilagringsystem; Hybridkraftverk; Frekvensreglering; Modellering; XGBoost Regression;

    Abstract : The rapidly evolving Nordic Power System demands enhanced flexibility and robustness in electricity production. The traditional role of hydropower plants in regulating the grid frequency has been challenged by new criteria for dynamic stability, which some units struggle to meet due to their relatively poor dynamic performance.

  4. 3. Modelling and Investigation of Control of a Power Infrastructure Resource Management System for a Radio Base Station : A study on sustainable power management for ICT infrastructure.

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

    Author : Gustav Lenart; [2023]
    Keywords : Hybrid Dynamical Systems; Resource Management; Hybrid Automaton; Sustainable solutions for Wireless technology; Hybrid Dynamiska System; Resurshantering; Hybrid Automaton; Hållbara lösningar för trådlös teknologi;

    Abstract : In order to minimize greenhouse gas emissions and operational cost related to the ICT-infrastructure the power management method of a Radio Base Station (RBS) or Base Transceiver Station (BTS) at Ericsson is studied and modelled. The major load demand at RBS’s are due to uplink and downlink data traffic. READ MORE

  5. 4. Experimental Testing of Solar Photovoltaic/Thermal Collectors for Low Temperature Heat Pump Integration

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Jaakko Eskola; [2023]
    Keywords : Solar photovoltaic thermal; PVT; heat pump; thermal performance; ISO 9806:2017; Solhybrid; PVT; värmepump; termisk prestanda; ISO 9806:2017;

    Abstract : A hybrid photovoltaic/thermal (PVT) collector enables simultaneous electricity and heat production from a single solar module. Integrating PVT collectors with a ground source heat pump (GSHP) improves the seasonal performance of the heating system and prevents from temperature degradation of the ground. READ MORE

  6. 5. Hydrogen Fuel Cell Lifetime Simulation in Marine Applications

    University essay from KTH/Kraft- och värmeteknologi

    Author : Yifeng Zhong; [2022]
    Keywords : maritime transportation; FEMFC; lifetime simulation; degradation mechanism; empirical relationship; semi-empirical approach; sjötransport; PEM-bränsleceller; livslängdssimulering; nedbrytningsmekanism; empiriskt samband; semi-empiriskt tillvägagångssätt;

    Abstract : Maritime transportation emits about 3% of global greenhouse gas, International Maritime Organization (IMO) aims to reduce shipping’s emissions by 50% with respect to 2008 levels. Proton exchange membrane fuel cells (PEMFCs) are considered among the most promising clean technologies for decarbonizing the maritime sector. READ MORE
