  1. 1. Classification of ultrasonic signals using machine learning to identify optimal frequency for elongation control : Threaded fastening tools

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

    Författare :Mazen Bahy; [2022]
    Nyckelord :Machine Learning; Convolutions Neural Network CNN ; Barker signals; Ultrasonic sensors; Clamp-force; Threaded fastening assembly; Maskininlärning; konvolutionellt neuralt nätverk; Barker-signaler; Ultraljudssensorer; klämkraft; Åtdragningsmontering;

    Sammanfattning : Studying the preload in a screw joint has been the focus of today’s industry. The manufacturer reflects that demand by investigating different opportunities and techniques to develop this area. There are four different ways of controlling the tightening of bolts and joints to achieve the required clamp force that can hold for a specific preload. LÄS MER

  3. 2. Hydrological modelling of a recycling facility and landfill

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Mazen Tawfik; [2022]
    Nyckelord :Parsimonious approach; Lumped modelling; Surface water; Landfill; Leachate water; Storage reservoirs.; Technology and Engineering;

    Sammanfattning : A parsimonious lumped model for simulating a catchment composed of a landfill and recycling facility were developed. The modelling results showed an acceptable conformity with the observed values with NSE of 0.54 and R2 of 0.56 in hourly simulations, though the results were characterized by a general underestimation.

  4. 3. Offshore Wind Power Foundations' Corrosion Protection Strategy : Anlysis remotely controlled corrosion protection system and comparison to traditional corrosion protection of offshore wind foundation

    Kandidat-uppsats, Linnéuniversitetet/Sjöfartshögskolan (SJÖ)

    Författare :Mazen Alhamalawi; [2021]
    Nyckelord :natural potential; corrosion; corrosion protection system; GACP; ICCP and sacrificial anodes; naturlig potential; korrosion; korrosionsskyddssystem; GACP; ICCP och offeranoder;

    Sammanfattning : När en metall är omgärdad av en elektrolyt, så som havsvatten, kommer det att byggas upp en naturlig potential. Det sker en elektronvandring mellan materialet och havsvattnet och ju större potentialskillnad desto större sannolikhet att metallen kommer korrodera. LÄS MER

  5. 4. A comparative study of the materials of Villa Zero project using LCA

    Magister-uppsats, Högskolan Dalarna/Institutionen för information och teknik

    Författare :Juma Alkhuder; Mazen Alnabhani; [2021]
    Nyckelord :Life cycle assessment LCA ; Villa Zero; One Click LCA; Construction and building materials.;

    Sammanfattning : In this thesis a future-world case was undertaken of the life cycle assessment (from cradleto grave) of a single-family house. The house is expected to be constructed by the end of2021 in Borlänge, a city located in Dalarna County. LÄS MER

  7. 5. Comparative analysis of Machinegenerated questions (Quillionz) and Human-generated questions

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

    Författare :Mazen Bahy; [2020]
    Nyckelord :;

    Sammanfattning : This thesis investigates the quality of machine-generated questions compared to human-generated questions in terms of the grammar and the clarity of the questions. Limited work has previously been done in the area of comparing them in terms of the grammar and the clarity using different statistic methods to analyze the results. LÄS MER
