  1. 1. Prediction of Plastic Fragments in Recycled Paper Using Near-Infrared Spectroscopy

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Fidan Alieva; [2023]
    Nyckelord :Near-infrared spectroscopy; paper packaging; barrier materials; recycling; multivariate data analysis; Nära-infraröd spektroskopi; pappersförpackningar; barriärmaterial; återvinning; multivariat dataanalys;

    Sammanfattning : Sustainability has gained a lot of attention in the field of research. Researchers and consumers both prioritize sustainability and environmental issues over previously dominant materials, such as plastic. Packaging and disposable items that used to be made of plastic have largely been replaced with paper. LÄS MER

  3. 2. Människan först för en hållbar stad : Bryta bilen som norm för att välja gång och cykel

    Kandidat-uppsats, Högskolan Dalarna/Samhällsbyggnadsteknik

    Författare :Peter Sahrin; [2023]
    Nyckelord :Transport-efficient society; accessibility; behavior change; senses; function mix; target points; walking; cycling; Transporteffektivt samhälle; tillgänglighet; beteendeförändring; sinnen; funktionsblandning; målpunkter; gång; cykel;

    Sammanfattning : Since the 1950s, private car use in Sweden has grown rapidly. The car and a significant aid that became a symbol of freedom and flexibility has today become a necessity that many consider themselves unable to live without. LÄS MER

  4. 3. Coexistence of Dual Inductive Wireless Power Transfer Systems

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Eneas Hållsten; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Wireless power transfer is emerging into everyday life. The idea is to create a more convenient way of charging, or at least powering, devices. LÄS MER

  5. 4. Niobium Ohmic Contacts for Cryogenic Indium Phosphide High-Electron-Mobility Transistors

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Linnéa Bendrot; [2022]
    Nyckelord :Ohmic contacts; high-electron-mobility transistor; InP; Nb films; cryogenic electronics; low-noise amplifier; quantum computing; transfer length method; superconductivity; contact barrier resistance; Ohmska kontakter; högelektronmobilitetstransistorer; indiumfosfid; niob; tunnfilm; kryogen elektronik; lågbrusförstärkare; kvantdatorer; Transfer Length-metod; supraledning; kontakt- barriärresistans;

    Sammanfattning : Ohmic contacts are crucial components in semiconductor devices such as transistors and diodes, and lowering their contact resistance is an important factor in device performance enhancement. This is especially important for low-noise amplifiers (LNAs) where device noise temperature decreases both directly and indirectly with decreasing contact resistance. LÄS MER

  7. 5. Solceller på bullerplank : Möjligheter och begränsningar med en ovanlig placering av solceller

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

    Författare :Shyar Fatah; Ahmed Mustafa; [2021]
    Nyckelord :Solenergi; Solceller; Solinstrålning; Solelproduktion; Bullerplank;

    Sammanfattning : This thesis deals with possibilities for solar cells on noise boards. As global warming increases, interest in reducing climate impact has also increased among people. Until today, fossil fuels are the dominant energy source that has a negative impact on the environment. LÄS MER
