    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Lisa Svensson; [2024]
    Nyckelord :aerospace; HPGP; ECAPS; ANSYS; conjugate heat transfer; thruster; space;

    Sammanfattning : This master's thesis was conducted in collaboration with ECAPS, where a conjugate heat transfer analysis on their High Performance Green Propulsion (HPGP) 22N thruster was done. ECAPS is a Swedish propulsion company specializing in green propulsion. They develop thrusters for spacecraft orbit and attitude control, utilizing the propellant LMP-103S. LÄS MER

  3. 2. Techno-economic analysis and simulation of low temperature district heating networks

    Master-uppsats, Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

    Författare :Ilia Iarkov; [2023]
    Nyckelord :Low-temperature district heating; Modelica; BTES; LCA; LCC; Technology and Engineering;

    Sammanfattning : The continuous increase in global energy consumption has led to a greater focus on the energy required for heating buildings. This thesis presents a techno-economic model for analysing low-temperature district heating networks coupled with a geothermal heat source. LÄS MER

  4. 3. Overstock of aftermarket parts in Africa at Sandvik Stationary Crushing and Screening

    Master-uppsats, Lunds universitet/Produktionsekonomi

    Författare :Mattias Johannesson; [2023]
    Nyckelord :Inventory management; Overstock; Excessive inventory; Obsolete inventory; Redistribution; Technology and Engineering;

    Sammanfattning : Title: Overstock of aftermarket parts in Africa at Sandvik Stationary Crushing and Screening Author: Mattias Johannesson Supervisor: Fredrik Olsson, Division of Production Management Background: An increase of customer expectations such as demand for more customizable options, shorter lead times and availability puts more and more pressure on a company's logistical processes. With fluctuating demand, inconsistent lead times and uncertainty around the world, variability is present and adds complexity to the logistical processes and needs to be handled appropriately to lower costs and match supply and demand.

  5. 4. The effect of high pressure homogenization on emulsions containing oat β-glucan : a study of viscosity, stability and molecular weight

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Dominika Kiesling; [2023]
    Nyckelord :oat; β-glucan; high pressure homogenization; emulsion; stability; food technology; Agriculture and Food Sciences;

    Sammanfattning : This master thesis project has been conducted in cooperation with Lantmännen AB who are producers of PromOat® - an oat β-glucan powder concentrate. The main objective of this thesis was to investigate the properties of emulsions containing PromOat® oat β-glucan, focusing on the viscosity, stability, and molecular weight before and after high pressure homogenization (HPH) at pressures of 100, 150 and 200 bars.

  7. 5. Virtual Sensing for Cluster Vacuum Control

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Carl Egenäs; Axel Sacilotto; [2023]
    Nyckelord :;

    Sammanfattning : The purpose of this project was to develop a virtual sensing model in order to estimate the vacuum level in the milking cluster with data collected further along the milk tube. Measuring the cluster vacuum level is desirable for many applications, such as control and monitoring, but due to the cow's tendency to kick, chew and stomp on anything within reach, placing a sensor in or close to the cluster is both difficult and impractical.
