  2. 1. The perceived impact of stroke and feasibility of a mobile phone supported ADL intervention in Uganda

    Author : Julius Tunga Kamwesiga; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Background: Rehabilitation after stroke in Uganda is limited due to poor infrastructure, inadequate number of professionals and the poor socio-economic situation of the people. A sizeable number of patients with moderate or severe stroke are admitted to hospitals for initial care, but the majority do not receive rehabilitation. READ MORE

  4. 2. Managing discontinuous changes in complex products : Cases involving the development and market introduction of heavy hybrid-electric buses

    Author : Dedy Sushandoyo; Christian Berggren; Thomas Magnusson; Mats Magnusson; Linköpings universitet; []
    Keywords : Discontinuous changes; complex products; discontinuous innovations; technology selections; development and market introduction; heavy hybrid-electric vehicles; the heavy vehicle industry; Diskontinuerliga förändringar; komplexa produkter; diskontinuerliga innovationer; teknologival; utveckling och marknadsintroduktion; tunga eldrivna hybridbussar; tunga bilindustrin;

    Abstract : This is a study about managing the development of discontinuous changes in complex products characterised by integration of a significant amount of new technologies and firms’ existing technologies and market introduction of such products. In particular, this study analyses how firms’ technology selections influence the conditions for the firms to manage such development and market introduction. READ MORE

  5. 3. Deactivation of emission control catalysts for heavy-duty vehicles : Impact of biofuel and lube oil-derived contaminants

    Author : Sandra Dahlin; Lars Pettersson; Isabella Nova; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NH3-SCR; Cu-SSZ-13; V2O5-WO3 TiO2; catalyst deactivation; diesel oxidation catalyst; sulfur; phosphorus; biodiesel; heavy-duty; emission control; regeneration; alkali metals; NH3-SCR; Cu-SSZ-13; V2O5-WO3 TiO2; katalysatordeaktivering; dieseloxidationskatalysator; svavel; fosfor; biodiesel; tunga dieselmotorer; avgasrening; regenerering; alkalimetaller; Chemical Engineering; Kemiteknik;

    Abstract : Catalytic emission control is used to reduce the negative impact of pollutants from diesel exhausts on our health and on the environment. For a heavy-duty truck, such a system consists of a diesel oxidation catalyst (DOC), a diesel particulate filter (DPF), a selective catalytic reduction (SCR) catalyst, and an ammonia slip catalyst (ASC).

  6. 4. Adaptive Lateral Model Predictive Control for Autonomous Driving of Heavy-Duty Vehicles

    Author : Goncalo Collares Pereira; Jonas Mårtensson; Bo Wahlberg; Henrik Pettersson; Daniel Axehill; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Model Predictive Control; Control Stability; Experimental Evaluation; Fleet Evaluation; Adaptive Control; Automatic Control; Autonomous Vehicles; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Autonomous Vehicle (AV) technology promises safer, greener, and more efficient means of transportation for everyone. AVs are expected to have their first big impact in closed environments, such as mining areas, ports, and construction sites, where Heavy-Duty Vehicles (HDVs) operate. READ MORE

  7. 5. A Framework for Fatigue Analysis of Carbon Fiber Reinforced Polymer Structures

    Author : Sara Eliasson; Zuheir Barsoum; Per Wennhage; Kim Branner; KTH; []

    Abstract : Our society depends on functional road communication, and Heavy Duty Vehicles (HDVs) offer convenient and limitless possibilities of transport and services. However, HDVs account for a quarter of the European Union's CO2 road emissions. There is a substantial need to reduce the CO2 emissions of HDVs to ensure a low negative environmental impact. READ MORE
