  1. 1. Kånkels hus

    Kandidat-uppsats, KTH/Arkitektur

    Författare :Joel Stadius; [2023]
    Nyckelord :EPA; Folkets hus; Raggare; A-traktor; Nynäshamn;

    Sammanfattning : Epa kulturen börjar idag nå ut till den stora massan genom Epa-dunk musiken. Själva fortskaffningsmedlet är dock fortfarande relativt otillgängligt för många. Mycket av möjligheterna att äga och kunna reparera en epa traktor kommer genom ungdomars föräldrar och deras ekonomiska möjligheter. LÄS MER

  3. 2. Hällby besökscenter

    Kandidat-uppsats, KTH/Arkitektur

    Författare :Lars Sundqvist; [2022]
    Nyckelord :hjälmare kanal; besökscenter; utställning; historia; arboga; sluss;

    Sammanfattning : By order of King Gustav II Adolf, a canal was started in 1629 between Hjälmaren and Mälaren to facilitate the transport of goods from the West Coast to Bergslagen and Stockholm and thus also avoid the detour through the strait between Denmark and Skåne. More than 500 men were employed for the canal construction and it took them 10 years to connect a waterway between the two large lakes. LÄS MER

  4. 3. Identifying Important Features to Minimize Hole Deviation in Percussive Drilling

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Ketan Dhananjay Deshpande; [2021]
    Nyckelord :Bending; Buckled profile; Drilling; Hole deviation; Mathematical model; Böjning; Buckled profil; Borrning; Hålavvikelse; Matematisk modell;

    Sammanfattning : Hole deviation is one of the most significant problems in drilling applications. Deviated holes result in inefficient blasting and have severe economic impacts due to increased equipment consumption. Conversely, straighter holes help in increasing production scales and reduce operational costs. LÄS MER

  5. 4. An Investigation of the breakage process of particles : With help of experimental results and discrete element methods

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

    Författare :Ronni Bashiry; [2021]
    Nyckelord :Geotechnical Engineering; Breakage; Fracture; Spherical particles; DEM; Modelling; Numerical modelling;

    Sammanfattning : In this study the breakage mechanics of brittle glass marbles was investigated. The pro-cess was to firstly investigate them in laboratory environment. The marbles or specimens was loaded until a crushing breakage occurred in a single point load test called Single Sphere Point load test in this document. LÄS MER

  7. 5. Numerical study of the effect of thermal ice loads on concrete dams

    Master-uppsats, KTH/Betongbyggnad

    Författare :Imal Zuwak; Wasseem Kordoghly; [2020]
    Nyckelord :Arch dam; Buttress dam; Concrete; Finite element analysis; Ice load; Valvdamm; Lamelldamm; Betong; Finit elementanalys; Islast;

    Sammanfattning : It is essential to understand the mechanics of ice load and how it affects concrete dams located in a cold climate, such as Sweden, where the temperature becomes sufficiently cold to freeze the surface of the reservoir. The purpose of this thesis is to study ice load distribution along concrete dams, and its response during the application of an ice load. LÄS MER
