  1. 21. Evaluating the Impact of Altered Electricity Systems

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Miljö- och energisystem

    Författare :Carolin Bangay; [2019]
    Nyckelord :Linear Programming; Transmission; Energy Systems; Green House Gas; Emissions; Electricity Systems; Modelling.; Technology and Engineering;

    Sammanfattning : In the light of the importance of climate change and the emissions that have induced it, the ability to calculate the effect on emissions by changing transmission capacity is vital. A model to perform such indicative calculations is developed in this thesis. LÄS MER

  2. 22. Reliability – based analysis of embankment dams

    Master-uppsats, KTH/Jord- och bergmekanik

    Författare :Xiaochen Liu; [2019]
    Nyckelord :Embankment dams; reliability-based analysis; slope stability analysis; internal erosion; dam safety; fyllningsdammar; tillförlitlighetsbaserad analys; analys av släntstabilitet; inre erosion; dammsäkerhet;

    Sammanfattning : Embankment dams are widely used as water-retaining structures through the world. Two principal structural failure modes of embankment dams are internal erosion and slope instability. The objective of this thesis is to investigate the feasibility of applying probabilistic methods in embankment dam assessment. LÄS MER

  3. 23. Improvement Strategies in Construction Sites : Development of Rapid Site Assessment for House-building Industry

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Pontus Urban; [2019]
    Nyckelord :Rapid Site Assessment; RSA; Lean; Lean Construction; House-building industry;

    Sammanfattning : The construction industry has deteriorated during the past 40 years. Up to 35 % of the production cost is from wastes. The manufacturing industry has had an opposite development, in many cases owing to the contributions of Lean Production and various assessment tools. LÄS MER

  4. 24. Gland Segmentation with Convolutional Neural Networks : Validity of Stroma Segmentation as a General Approach

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :THOMAS BINDER; [2019]
    Nyckelord :segmentation; deep learning; convolutional neural networks; machine learning; artificial intelligence;

    Sammanfattning : The analysis of glandular morphology within histopathology images is a crucial step in determining the stage of cancer. Manual annotation is a very laborious task. It is time consuming and suffers from the subjectivity of the specialists that label the glands. LÄS MER

  5. 25. The Effectiveness of Evacuation Alarms in Multi-Hazard Environments

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Robin Magnusson; Claude Pagnon Eriksson; [2019]
    Nyckelord :Evacuation; evacuation alarms; auditory alarms; alarm perception; perceived urgency; multi-hazard.; Technology and Engineering;

    Sammanfattning : The aim of this thesis is to investigate the effectiveness of using specific alarms for each hazard versus the effectiveness of using a single alarm for all hazards in multi-hazard facilities. The research was conducted by disseminating online questionnaires containing audio files of different alarms to occupants of multi-hazards facilities and conducting interviews with safety experts working at multi-hazard facilities.
