  1. 1. Investigating the effect of grinding method on ore beneficiation behaviour

    University essay from Luleå tekniska universitet/Mineralteknik och metallurgi

    Author : Mellisa Tanaka Mundida; [2023]
    Keywords : flotation; grinding; liberation; chalcopyrite; beneficiation; grinding method; selectivity index; VRM; Aitik ore; rodmill; particle shape;

    Abstract : Commodity projection studies anticipate an exponential increase in copper demand and decreasein mill grade of deposits currently exploited globally. Most of this demand is driven by theindispensable use of copper in electrification and currently, the growing demand in the contextof the green transition. READ MORE

  3. 2. Gravity water waves over constant vorticity flows: from laminar flows to touching waves

    University essay from Lunds universitet/Matematik (naturvetenskapliga fakulteten); Lunds universitet/Matematikcentrum

    Author : Francisco Gonçalves Jorge Dias de Carvalho; [2023]
    Keywords : Partial differential equations; Water waves; Euler equations; Free boundary problem; Bifurcation theory; Nonlinear functional analysis; Hilbert transform; Mathematics and Statistics;

    Abstract : In a recent paper, Hur and Wheeler proved the existence of periodic steady water waves over an infinitely deep, two-dimensional and constant vorticity flow and subject to gravity whose profile overhangs, among which, waves whose surface touches at a point, enclosing a bubble of air. We take this further, proving the existence of a continuous curve of water waves from a laminar flow up to a touching wave for fixed non-zero gravity. READ MORE

  4. 3. Mescape - A probabilistic mesoscopic model for fire evacuation in large gatherings

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Lorenzo Contini; [2022]
    Keywords : Human behaviour; crowd evacuation; mesoscopic modelling; hydraulic model; large gatherings; fire safety; performance-based design; quantitative risk assessment; consequence analysis; uncertainty analysis; probabilistic modelling; Technology and Engineering;

    Abstract : This study presents a mesoscopic model that predicts pedestrian evacuation in large gatherings with probabilistic methods. The model is based on a coarse network representation of buildings, where occupants are treated at a different scale according to their location. READ MORE

  5. 4. The Beveridge Curve : A comparison between the three largest labour market regions in Sweden; Stockholm-, Västra Götaland- and Skåne county and the effect of the building of the Öresund Bridge on the labour market matching efficiency of Skåne county.

    University essay from Linnéuniversitetet/Institutionen för nationalekonomi och statistik (NS)

    Author : Nelly Sand; [2021]
    Keywords : Beveridge curve; matching function; unemployment; vacancy; exogenous shock; Sweden; Stockholm; Västra Götaland; Skåne; county.;

    Abstract : This paper investigates the relationship between vacant job positions and unemployed workers, illustrated by the Beveridge curve, a tool for observing the matching process and the condition of a labour market. The Swedish case is studied together with its three largest labour market regions, i.e. READ MORE

  6. 5. Test Equipment for Physical Testing of Vibration Isolator

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : ADAM ALVETEG; MARKUS JOHANSSON; [2021]
    Keywords : Test rig; vibration isolator; hysteresis; Testrigg; vibrationsisolator; hysteres;

    Abstract : Vibrations is a phenomenon that can cause problems to systems if not dealt with. In heavy duty trucks, vibrations are mainly caused by uneven roads and from the combustion engine. Vibrations can damage components, reduce their service life and cause discomfort for the driver.
