  1. 1. Assessment of Raw Materials in Stainless Steelmaking-Their Energy Consumption and Greenhouse Gas Emission

    Författare :Wei Wenjing; Anders Tilliander; Peter Samuelsson; Pär Jönsson; Ye Guozhu; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; static process model; mass and energy balance; molybdenum; nickel; phosphorus; stainless steel; life cycle assessment; GHG emission; energy consumption; statisk procesmodell; mass- och energibalans; molybden; nickel; fosfor; rostfritt stål; livscykelanalys; växthusgasutsläpp; energiförbrukning; Metallurgical process science; Metallurgisk processvetenskap;

    Sammanfattning : In stainless steelmaking, around 68% of the total greenhouse gas emissions come from the processing of raw materials. Thus, it is important for steelmakers to make efforts together with their raw material suppliers to implement low-carbon initiatives. To facilitate such initiatives, assessment of raw materials will provide guidance. LÄS MER

  3. 2. Bygga - Bruka - Riva : Energianvändning i småhus ur ett kretsloppsperspektiv

    Författare :Karin Adalberth; Avdelningen för Byggnadsfysik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy use; energy; single-unit dwellings; life-cycle; livscykelkostnader; småhus; LCA; energiförbrukning; kretslopp;

    Sammanfattning : This report deals with single-unit dwellings built in 1991 and 1992 in a city called Orebro, Sweden.The houses are prefabricated and the frameworks are made of wood. The aim of the essay is to present the total use of energy during the life-cycle of single-unit dwellings, taking their mode of construction into account. LÄS MER

  4. 3. The Robustness and Energy Evaluation of a Linear Quadratic Regulator for a Rehabilitation Hip Exoskeleton

    Författare :Rabé Andersson; Niclas Björsell; Daniel Rönnow; Gianni Borghesan; Högskolan i Gävle; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hip Rehabilitation Exoskeleton; Robust Controller; Energy Consumption; Series Elastic Actuator SEA ; LQR Control; Luenberger State Observer; Torque Control; Höftexoskelett för rehabilitering; Robust reglering; Energiförbrukning; serieelastiskt manöverdon SEA ; LQR reglering; Luenberger State Obser-ver; Moment reglering;

    Sammanfattning : The implications of gait disorder, muscle weakness, and spinal cord injuries for work and age-related mobility degradation have increased the need for rehabilitation exoskeletons. Specifically, the hip rehabilitation exoskeletons due to a high percentage of the mechanical power is generated by this join during the gait cycle. LÄS MER

  5. 4. Quantifying Gait Characteristics and Neurological Effects in people with Spinal Cord Injury using Data-Driven Techniques

    Författare :Minh Truong; Elena Gutierrez-Farewik; Ruoli Wang; Emelie Butler Forslund; Åke Seiger; Peter Christian Raffalt; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; gait analysis; pathological gait; biomechanics; health informatics; metabolic cost; unsupervised learning; nonparametric regression; shapley addictive explanations; gånganalys; funktionsnedsättning; gångpatologi; energiförbrukning; maskininlärning; hälsoinformatik; biomekanik; AI; Teknisk mekanik; Engineering Mechanics;

    Sammanfattning : Spinal cord injury, whether traumatic or nontraumatic, can partially or completely damage sensorimotor pathways between the brain and the body, leading to heterogeneous gait abnormalities. Mobility impairments also depend on other factors such as age, weight, time since injury, pain, and walking aids used. LÄS MER
