    Sammanfattning : A successful company is characterized by shared values, a clear vision, continuous improvements and everyone’s commitment. By consistently striving to achieve and exceed needs and expectations, quality becomes a cornerstone of long term success. LÄS MER

  3. 2. CFD investigation of a unit cell inside a Plate Heat Exchanger

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Mattias Ly; [2023]
    Nyckelord :Plate Heat Exchanger; CFD; Computational Fluid Dynamics; LES; Large Eddy Simulation; Periodic; Unit Cell; Technology and Engineering;

    Sammanfattning : A numerical investigation of the unit cell approach has been done to reduce the computational cost for CFD (Computational Fluid Dynamics) of plate heat exchangers (PHE) at Alfa Laval. The reduced cost would enable LES (Large Eddy Simulation) to be done which would give a more detailed and accurate insight into the flow and heat transfer processes of the PHE. LÄS MER

  4. 3. Robust Radar Platsigenkänning och Verifiering

    Uppsats för yrkesexamina på avancerad nivå, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Mattias Karlsson; [2022]
    Nyckelord :;

    Sammanfattning : En platsigenkänningsmetod ska kunna upptäcka när tidigare besökta platser besöks igen. Detta är en viktig del för navigering av autonoma fordon och mobila robotar. Genom att känna igen tidigare besökta platser, kan en bättre uppskattning av den nuvarande positionen och den tidigare körda vägen göras. LÄS MER

  5. 4. Managing a Work Environment using Sensor Networks

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

    Författare :Mattias Lind; Fredrik Karlsson; [2021]
    Nyckelord :Embedded Systems; Work Environments; Sensor Networks; Inbyggda System; Arbetsmiljöer; Sensornätverk;

    Sammanfattning : During the last decade sensor networks and Internet of Things have been gaining a lot of attention. One area where it is still fairly unused is to manage work environments. With sensor networks and Internet of Things devices it is possible to measure and control noise levels, air quality and most other aspects of reality. LÄS MER

  7. 5. Evaluation of Traction Control Systems for an Electric Forklift Truck

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Mattias Karlsson; Sebastian Johansson; [2021]
    Nyckelord :forklift; traction control; maximum transmissible torque; model following control; sliding mode control; slip; asr; tcs; mfc; mtte; smc; electric vehicle; master thesis;

    Sammanfattning : This thesis evaluates different controllers for traction control on an electric forklift truck and has been done in cooperation with Toyota Material Handling Manufacturing Sweden. The need for a traction control system has increased with the introduction of lithium-ion batteries replacing the older lead-acid batteries, reducing the battery weight and therefore the downward force on the driving wheel increasing the risk for slip.
