  1. 1. Fire Safety of Facades

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Bogdan-Grigore Branisteanu-Albulescu; [2019]
    Keywords : polystyrene; graphene; façade; pyrolysis; Technology and Engineering;

    Abstract : Façade fires are a big concern due to past incidents and the large number of victims encountered. Vertical flame spread mechanism specific to this type of fires is a complex phenomenon with parameters that are often difficult to be coupled. READ MORE

  2. 2. Internet of Things mesh network : Using the Thread networking protocol

    University essay from Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013)

    Author : Anton Alm; [2019]
    Keywords : iot; internet of things; thread; mesh network;

    Abstract : This thesis summarizes my project in setting up a Thread network. The idea of this project was presented by the company ÅF in Karlstad, Sweden. ÅF wishes to upgrade their current demonstrator for IoT. The current demonstrator includes Azure Cloud component, Raspberry Pi, Bluetooth and Arduino components. READ MORE

  3. 3. Numerical Study on Hydrodynamic Characteristics of Flood Discharge Tunnel in Zipingpu Water Conservancy Project : Using RANS equations and the VOF model

    University essay from Uppsala universitet/Elektricitetslära; Uppsala universitet/Elektricitetslära

    Author : Micaela Hamberg; Signe Dahlin; [2019]
    Keywords : VOF; RANS; Navier-Stokes; Spillway; Discharge tunnel; ANSYS; Fluent; CFD; Grid convergence index; Design of spillway; Cavitation; Gambit; k-epsilon; Ansys Gambit;

    Abstract : To avoid the large amount of damage that floods can cause, spillway tunnels are used to control water levels. To ensure the safety of water transportation through spillway tunnels, the behaviour of the water throughout the tunnel is important to know. READ MORE

  4. 4. FrankZlicer : Direct slicing using arcs

    University essay from Mittuniversitetet/Avdelningen för data- och systemvetenskap

    Author : Johan Franzén; [2019]
    Keywords : FDM; Additive Manufacturing; 3D-printing; CAM; STEP; G-Code; Arc; Slicer;

    Abstract : 3D printing a CAD modelnormally requires conversion into a polygon mesh, usually an STL-file, in orderto be able to load the model in the slicer. This conversion destroys roundsurfaces and replaces them with flat surfaces. Slicing a polygon mesh resultsin one or more polygons, consisting of a number of straight lines. READ MORE

  5. 5. Simulation of solidification and cooling of a casting product using COMSOL Multiphysics

    University essay from Lunds universitet/Institutionen för Energivetenskaper

    Author : Tom Allen; [2019]
    Keywords : Heat transfer; casting; phase change; COMSOL Multiphysics; Technology and Engineering;

    Abstract : In this project, the cooling and solidification processes for a Valmet Foundry product have been simulated in order to shorten the cooling time. The study has also been done in cooperation with RISE Swecast in Jönköping, as a part of finding ways to make casting procedures more energy efficient. READ MORE
