  1. 1. Impact of different light sources on the responses of moth

    University essay from Högskolan i Halmstad

    Author : Yanhe Zhou; [2021]
    Keywords : Artificial light at night ALAN ; Greater wax moth; Light Attraction; light emitting diodes; LED; Galleria mellonella;

    Abstract : In recent decades, the negative effects of artificial light at night on natural ecosystems have attracted the attention of ecologists. Studies have shown that artificial light at night leads to a considerable reduction in insects and has a worrying impact on terrestrial ecosystems, including nocturnal insects (e.g. Lepidoptera) such as moths.

  3. 2. Bi-directional Low Pass Filter and Mixer Design

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Sharath Thandava Murthy; Meshach Milon Paul Pear Pradeep Kumar; [2020]
    Keywords : Technology and Engineering;

    Abstract : This report presents the research and implementation of a bidirectional filter and mixer combination for the transceiver chain in 5G TDD equipment. The main objective of this project is to find a feasible design for mixer and low pass filter to reuse the same hardware blocks for both transmitter and receiver chain. READ MORE

  4. 3. Nanoscale electrical properties of heterojunction interfaces for solar cells : modeling and experiments

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Martin Eriksson; [2018]
    Keywords : solar cell; heterojunction; ZnO; Cu2O; Comsol; atomic force microscopy; I-V characteristics;

    Abstract :   A numerical model have been developed in order to describe and achieve deeper understanding of experimentally obtained I-V curves from Cu2O/ZnO p-n heterojunctions for potential use as future solar cell material. The model was created using the simulation software COMSOL Multiphysics® and their semiconductor module. READ MORE

  5. 4. Diode laser spectroscopy for oxygen detection in the lungs of infants

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Atomfysik

    Author : Peilang Liao; [2016]
    Keywords : GASMAS; Tunable laser; Transport theory; 3D phantom; Diagnoses; Gas; Lung; Physics and Astronomy;

    Abstract : This thesis work is part of a larger project with final goal to be able to measure the oxygen concentration in the lungs of infants, using non-invasive laser spectroscopy. This thesis is specifically dealing with simulations of light transport through the upper body of infants, as well as constructing a tissue-like model (phantom) that can be used in experiments.

  6. 5. Comparative Study of Dissuasive Emergency Signage

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Joakim Olander; [2015]
    Keywords : Dissuasive; emergency signage; exit signage; paired comparison; evacuation; dynamic signage systems; path choice; risk perception; urgency; avrådande; utrymningsskyltning; jamförelsestudie; utrymning; aktivt system; val av utrymningsväg; riskperception; brådska; Technology and Engineering;

    Abstract : This thesis investigates dissuasive emergency signage conveying a message of not utilizing a specific exit door. The thesis analyzes and highlights which features of dissuasive emergency signage have the largest impact on observer preference, interpretation and noticeability of the signage, in addition to analyzing the possibility and effects of causing an increased sense of urgency amongst the observers.
