  1. 1. Sambandet mellan organisationsstöd och grupputvecklingsnivåer i tillfälliga projektgrupper : En kvantitativ studie som undersöker om grupputvecklingsnivå prediceras utifrån organisationsstöd?

    Magister-uppsats, Karlstads universitet/Handelshögskolan (from 2013)

    Författare :Gabriel Marouki; [2023]
    Nyckelord :Effective teams; Organizational support; Group development level; Project teams; IMGD.; Effektiva team; Organisationsstöd; Grupputvecklingnivå; Projektgrupper; IMGD.;

    Sammanfattning : Syftet med denna studie var att undersöka sambandet mellan organisationsstöd och grupputvecklingsnivåer. För att svara på studiens syfte har följande fråga formulerats: Kan grupputvecklingsnivå prediceras utifrån de 7 aspekter av organisationsstöd?Metoden som används i denna studie är en tvärsnittsundersökningsdesign med en kvantitativ ansats.

  3. 2. Agrivoltaic Implementation in Greenhouses : A Techno-Economic Analysis of Agrivoltaic Installations for Greenhouses in Sweden

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

    Författare :Henrik Gauffin; [2022]
    Nyckelord :Agrivoltaics; Agrophotovoltaics; Photovoltaics; Greenhouse; Battery Energy Storage System; Agrivoltaics for Greenhouses; Techno-Economic Assesment; AV; APV; PV.;

    Sammanfattning : Due to the growing population and climate change, the world will see an increase in demand for food, freshwater and renewable energy supply. Agrivoltaics has the possibility to address all these problems, by producing food and renewable energy but also by reducing water usage in agriculture. LÄS MER

  4. 3. Organic Solar Cell Fabrication and Study on the Influence of Spin-dependent Processes on the Photocurrent using Spin-sensitive Techniques

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fasta tillståndets fysik

    Författare :Ronja Olsmats Baumeister; Evelina Roxner; [2022]
    Nyckelord :EDMR; EPR; trEDMR; PEDOT:PSS; PCBM; P3HT; organic solar cells; osc; opv;

    Sammanfattning : Research in recent years on novel materials in organic solar cells (OSCs) have contributed to a rapid advancement in OSC efficiency. Here, OSCs with the well-studied organic semiconductors poly(3-hexylthiophene):[6,6]-phenyl C60-butyric acid methylester (P3HT:PCBM) in a bulk heterojunction structure were prepared to establish a baseline procedure for fabrication and spin-sensitive spectroscopy.

    Nyckelord :organic solar cells; OSC; polymer; interface; charge transfer; non-fullerene acceptor; PYT; PBDB-T; DFT; TD-DFT; conformation; alkyl groups; methylation; HOMO; LUMO; FMO; NTO; UV-Vis; DOS; exciton; exciton binding energy; dipole moment; open-circuit voltage; organiska solceller; OSC; polymer; gränssnitt; laddningsöverföring; icke-fullerenacceptor; PYT; PBDB-T; DFT; TD-DFT; konformation; alkylgrupper; metylering; HOMO; LUMO; FMO; NTO; UV-Vis; DOS; exciton; excitonbindningsenergi; dipolmoment; tomgångsspänning;

    Sammanfattning : Organic solar cells (OSCs) based on non-fullerene acceptors (NFAs) have attracted a great deal of attention in recent years due to their rapidly increasing efficiency and enormous potential. In this work, the optical and electronic properties of systems containing the very promising non-fullerene acceptor PYT have been thoroughly studied with the use of the density functional theory (DFT) and the time-dependent density functional theory (TDDFT).

  7. 5. Real-time characterization of fuel by Near-Infrared spectroscopy : Quantitative measurements of moisture content, ash content, heating value, and elemental compositions in solid biofuel mixtures

    Uppsats för yrkesexamina på avancerad nivå, Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Författare :Kajsa Edlund; Ali Ahmad Shahnawazi; [2021]
    Nyckelord :NIR; spectroscopy; solid biofuel mixtures; moisture content; ash content; heating value; elemental composition; boiler; CHP pant; CCS; CO2; emissions; NIR; spektroskopi; fasta biobränsleblandningar; fukthalt; ask innehåll; värmevärde; elementär komposition; panna; kraftvärmeverk; CCS; CO2; utsläpp;

    Sammanfattning : The global energy demand supplies mainly from fossil fuels, which is neither sustainable nor environmentally friendly and aims to global warming. Therefore, both more investments in renewable energy sources such as bioenergy are required, as well as new technologies such as carbon capture and storage (CCS) to handle the emissions from existing combined heat and power (CHP) plants.
