  1. 1. The complexity and variability of individuals' activity-travel patterns in Indonesia

    Författare :Dimas Bayu Endrayana Dharmowijoyo; Yusak Susilo; Anders Karlström; Frank Wiltox; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; day-to-day variability; needs-constraints interaction; non-instrumental variables; health condition; Transportvetenskap; Transport Science;

    Sammanfattning : Considering an individual’s day-to-day variability of activity-travel patterns will provide a more complete description of how an individual behaves to adapt the changing constraints and resources on different days. Without this day-to-day variability understanding, the individual’s behaviour would not be fully grasped and any suggested policy, planning and development would not completely achieve their desired objectives.

  3. 2. Impact of residential wood combustion on urban air quality

    Författare :Patricia Krecl; Christer Johansson; Johan Ström; Tami Bond; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; residential wood combustion; air quality; aerosols; black carbon; polycyclic aromatic hydrocarbons; particulate matter; particle size distributions; source apportionment; positive matrix factorization; compound-specific radiocarbon analysis; Earth sciences; Geovetenskap; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Wood combustion is mainly used in cold regions as a primary or supplemental space heating source in residential areas. In several industrialized countries, there is a renewed interest in residential wood combustion (RWC) as an alternative to fossil fuel and nuclear power consumption. LÄS MER

  4. 3. Assessment of balance control in relation to fall risk among older people

    Författare :Ellinor Nordin; Lillemor Lundin-Olsson; Anna Ramnemark; Gun-Britt Jarnlo; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; older people; falls; interactive gait; TUG; GUG; balance confidence; likelihood ratio; validity; reliability; risk factors; assessment; balance; gait; mobility; physical function; dual-task costs; step width; Physiotherapy; Sjukgymnastik fysioterapi;

    Sammanfattning : Falls and their consequences among older people are a serious medical and public health problem. Identifying individuals at risk of falling is therefore a major concern. LÄS MER

  5. 4. Neuroendocrine Stress Response after Burn Trauma

    Författare :Andreas Lindahl; Bengt Gerdin; Lisa Ekselius; Kristofer Rubin; Riddez Louis; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Burn; Injuries; Neuroendocrine; Intensive Care; Cortisol; Chromogranin A; Natriuretic peptides; Plastikkirurgi; Plastic Surgery;

    Sammanfattning : Some aspects of the stress response during acute intensive care for severe burns are described and quantified by measuring hormonal and neuroendocrine patterns and relating these to organ function in the short term. This includes an assessment of whether there are markers for the severity of stress that are better than conventional descriptors of the severity of a burn in predicting failing organ function.

  7. 5. Urban Travel Time Estimation from Sparse GPS Data : An Efficient and Scalable Approach

    Författare :Mahmood Rahmani; Harilaos Koutsopoulos; Nikolas Geroliminis; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; map-matching; path inference; sparse GPS probes; floating car data; arterial; urban area; digital road network; iterative travel time estimation; fixed point problem; Stockholm; taxi; Transportvetenskap; Transport Science;

    Sammanfattning : The use of GPS probes in traffic management is growing rapidly as the required data collection infrastructure is increasingly in place, with significant number of mobile sensors moving around covering expansive areas of the road network. Many travelers carry with them at least one device with a built-in GPS receiver. LÄS MER
