  1. 1. Experiment Design for System Identification on Satellite Hardware Demonstrator

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Elias Krantz; [2018]
    Nyckelord :LTU; Airbus; Attitude; Guidance; Control; AOCS; GNC; Kalman Filter; UKF; System Identification; SysId; Estimation; Determination; CMG;

    Sammanfattning : The subject of this thesis covers the process of online parameter estimation of agile satellites. Accurate knowledge of parameters such as moment of inertia and centre of mass play a crucial role in satellite attitude control and pointing performance. LÄS MER

  2. 2. AA-CAES physical modelling: integration of a 1D TES code and plant performance analysis

    Master-uppsats, Uppsala universitet/Tillämpad kärnfysik

    Författare :Luca Santo; [2018]
    Nyckelord :energy storage; balancing; grid; AA-CAES; CAES; peaks; energy scenarios; s-function; simulink; simscape; matlab; C ; TES; thermal energy storage; dumping; demand side management; power systems; turbine; compressor; cavern; CAS; compressed air; heat exchange;

    Sammanfattning : The focus of this thesis work was the development of an approachto couple a previosly existing Thermal Energy Storage (TES) modelwritten in C++ with a Simulink/Simscape plant model to simulate anAdvanced Adiabatic Compressed Air Energy Storage (AA-CAES) plant.After the creation and validation of such tool, the complete modelwas used to run simulations, with the aim of assessing the AA-CAESplant's performance under multiple patterns of charge anddischarge.

  3. 3. A strategic distribution model for an upscaling project at an emerging market - and a blockchain technology use case approach to the supply chain

    Master-uppsats, Lunds universitet/Teknisk logistik

    Författare :Anes Sestic; William Ribbing Dahlgren; [2018]
    Nyckelord :Distributed manufacturing; upscaling; supply chain planning; network planning; scenario planning; blockchain technology; business development; supply chain management; simulation modelling; transparency; traceability; Business and Economics;

    Sammanfattning : Background: Globalization is a phenomenon which has been around since the mid- 19th century, influencing companies to either expand existing markets or entering new markets, to seek new profits. For companies with a global supply chain, the total supply chain cost is a vital factor. LÄS MER

  4. 4. Moisture risks with CLT-panels subjected to outdoor climate during construction : focus on mould and wetting processes

    Kandidat-uppsats, KTH/Byggteknik och design; KTH/Byggteknik och design

    Författare :Johan Öberg; Erik Wiege; [2018]
    Nyckelord :moisture; CLT; massive wood; mould; WUFI; drying; construction; weather protection. best practice; fukt; KL-trä; massivt trä; mögel; WUFI; torkning; konstruktion; väderskydd; best practice;

    Sammanfattning : When going through relevant research, moisture safety guidelines and talking to builders, moisture experts and architects it is clear - and not surprising - that water and wood make no easy combination. The experiences from building with cross laminated timber (CLT) differ from building sites and there are good and bad examples building without weather protection. LÄS MER

  5. 5. Modelling and Simulation of Heat Pump Systems for Hybrid and Electrical Vehicles

    Master-uppsats, Linköpings universitet/Fordonssystem; Linköpings universitet/Fordonssystem

    Författare :Mikael Eriksson; Oskar Graffman; [2018]
    Nyckelord :Heat Pump;

    Sammanfattning : Hybridization and electrification of modern vehicles is today a reality. This effects the construction of the heating and cooling systems in vehicles where earlier the waste heat from the combustion engine was a great heat source. LÄS MER
