  1. 1. The hospital-wide patient flow - looking beyond borders for improved productivity

    Författare :Philip Åhlin; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Productivity; Barriers; Capacity utilization; Solutions; Healthcare; Operations Management; Patient flow; Strategy; Hospital-wide;

    Sammanfattning : Demand for healthcare is increasing at a faster pace than hospitals’ capacity. In search of new paths to reverse this development policy makers and healthcare managers look for new methodologies or concepts to improve productivity. One such concept is flow efficiency, focusing on how to better support the throughput of patients, and productivity. LÄS MER

  3. 2. Stability of plane Couette flow and pipe Poiseuille flow

    Författare :Per-Olov Åsén; Gunilla Kreiss; Jonathan Goodman; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydrodynamic stability; plane Couette flow; pipe Poiseuille flow; direct numerical simulations; resolvent; Fluid mechanics; Strömningsmekanik;

    Sammanfattning : This thesis concerns the stability of plane Couette flow and pipe Poiseuille flow in three space dimensions. The mathematical model for both flows is the incompressible Navier--Stokes equations. Both analytical and numerical techniques are used. We present new results for the resolvent corresponding to both flows. LÄS MER

  4. 3. Process Design for Ultrafiltration of Complex Process Streams

    Författare :Anna-Karin Nordin; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bleach plant effluent; Ultrafiltration; process design; optimization;

    Sammanfattning : Considerable effort has been dedicated over the years to model and simulate the ultrafiltration process. Most approaches are theoretical and therefore not applicable to industrial process streams. When treating such solutions, a combination of experiments and simulations is needed. LÄS MER

  5. 4. Decarbonising the Stainless Steelmaking through Alloy Solutions

    Författare :Wenjing Wei; Pär Jönsson; Peter Samuelsson; Birat Jean Pierre; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stainless steel; optimization; raw material; process; quality; decarbonisation; rostfritt stål; optimering; material; process; kvalitet; avkarbonisering; Materials Science and Engineering; Teknisk materialvetenskap;

    Sammanfattning : To reach the goal of the Paris Agreement, the reduction of greenhouse gas emissions (GHG)is becoming one of the most pressing issues in the world today. Unlike most other sectors, thestainless steel industry has a significantly higher burden from upstream emissions comparedto operational emissions. LÄS MER

  7. 5. Development Towards Sustainable Ironmaking : The IronArc Process

    Författare :Jonas Svantesson; Mikael Ersson; Robert Eriksson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; IronArc; Refractory wear; plasma generator; freeze-lining; Teknisk materialvetenskap; Materials Science and Engineering;

    Sammanfattning : The IronArc process is a novel process for a more sustainable production of liquid pig iron using electricity for heating and hydrocarbons for reduction. This thesis aims to facilitate its use by investigating possible refractory solutions and the gas blowing in the process which is done by a plasma generator. LÄS MER
