  1. 1. Energy audit of a single-family house in a city in the middle of Sweden

    Magister-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

    Författare :Daniela Valentina García Gimeno; [2023]
    Nyckelord :energy audit; building energy efficiency; building envelope; renewable sources; windows efficiency; insulation of houses in Sweden;

    Sammanfattning : The world is currently submerged in two big problems: supply energy crisis and climate change. It is clear that society has to do its best to overcome these challenges, and one effective way to mitigate their effects is by conducting an energy audit, which helps to identify the weaknesses and strengths of the buildings, enabling improvements in their thermal efficiency.

  3. 2. Analys och minskning av effektförlusterna i en borstlös likströmsmotor med vektorstyrning

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Lider Xavier Garcia Parrales; [2023]
    Nyckelord :Effektförluster Borstlös likströmsmotor BLDC Vectorstyrning Field-oriented Control FOC Blockkommutering Block commutation MTPA; Technology and Engineering;

    Sammanfattning : This report addresses power losses in an electric motor arising from various sources. The choice of motor control strategy can decrease efficiency if not implemented correctly or if the motor model in the control loop is overly simplified. LÄS MER

  4. 3. Flexible Sector Coupling (FSC) of Electrical and Thermal Sectors via Thermal Energy Storage (TES) : A Case Study on Oskarshamn Energi

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Raúl Calvo García; Jose María Marín Arcos; [2023]
    Nyckelord :Flexible sector coupling FSC ; district heating DH ; thermal energy storage TES ; heat pump HP ; capacity optimization; dispatch optimization; open-access tools; Flexibel sektorkoppling; fjärrvärme; termisk energilagring; värmepump; kapacitetsoptimering; leveransoptimering; verktyg med öppen tillgång;

    Sammanfattning : The integration of distributed energy sources and systems is of high relevance for the transition towards a more sustainable energy system. Taking into consideration the  amount of emissions produced by the heating sector, which account for at least half of the energy demand in buildings, district heating systems have the potential to play a key role in the transition, by enabling the integration of various energy sources and provide flexible energy services to the grid.

  5. 4. Exploring the vocabulary content of upper secondary EFL textbooks in Sweden : A corpus-based analysis of types, lexical coverage,progression, and academic words

    Magister-uppsats, Högskolan Dalarna/Engelska

    Författare :Dianne Valize Garcia; [2023]
    Nyckelord :vocabulary study; Academic Word List; word families; lexical coverage; EFL in Sweden;

    Sammanfattning : Vocabulary is considered the building block of language. Without it, communication breaks down. This degree project investigates the vocabulary types, progression, lexical coverage andacademic words in EFL upper secondary textbooks in Sweden. This was done by a corpus-based approach using corpus tools such as Range and AntWord Profiler. LÄS MER

  7. 5. Optimisation of parallel k-d trees using heuristics for neuron touch detection task

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

    Författare :Daniel Benedí García; [2022]
    Nyckelord :;

    Sammanfattning : Neuroscience has benefited from neuronal network simulation and an important task in the simulation is finding points in space where two neurites approach each other so a synapse could be formed. The task of finding the touching points could be seen as similar to the ray collision in ray tracing in computer graphics. LÄS MER
