  2. 6. Spatial variations of the urban climate and its influence on thermal comfort and behaviour

    Author : Fredrik Lindberg; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sky view factor; air temperature; surface temperature; GIS; raster modelling; mean radiant temperature; globe temperature; the SOLWIEG-model; human behaviour; outdoor activity;

    Abstract : The increased number of people living in urban areas emphasises the need for an improved understanding of how the urban climate affects human activity and behaviour. The spatial and temporal variation of climate within cities is an important factor in people’s health and well-being. READ MORE

  4. 7. Acclimation of plants to combinations of abiotic factors : connecting the lab to the field

    Author : Zsofia Réka Stangl; Vaughan Hurry; Lisa Ainsworth; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nitrogen; carbon dioxide; temperature; thermal acclimation; mycorrhiza; boreal forest; climate change; C:N balance; allocation; respiration; photosynthesis; terrestrial biosphere model;

    Abstract : Increasing atmospheric CO2 and other greenhouse gasses coupled to the accelerated rate of global warming puts plants and ecosystems under the strain of a rapidly changing abiotic environment. Understanding the impacts of changing global climate is a strong focus of plant science and the establishment of more resilient crop variants is an important goal for breeding programs. READ MORE

  5. 8. Moisture Influence on Structural Behaviour of Pavements : Field and Laboratory Investigations

    Author : Farhad Salour; Sigurdur Erlingsson; Guy Doré; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Falling Weight Deflectometer FWD ; backcalculation; unbound material; subgrade; seasonal variation; moisture content; spring-thaw; drainage; pavement stiffness; field test; pavement instrumentation; resilient modulus; permanent deformation; repeated load triaxial test; unsaturated soil; matric suction.; Civil and Architectural Engineering; Byggvetenskap; Transportvetenskap; Transport Science;

    Abstract : The structural behaviour of pavements in cold regions can considerably be affected by seasonal variation in environmental factors such as temperature and moisture content. Along with the destructive effect of heavy traffic loads, climatic and environmental factors can considerably contribute to pavement deterioration. READ MORE

  6. 9. Validation of heavy vehicle loading responses and temperature predictions in flexible pavements using field data

    Author : Denis Saliko; Sigurdur Erlingsson; Abubeker Ahmed; Denis Jelagin; Inge Hoff; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flexible pavements; Long heavy vehicles; Instrumented test section; Field validation; Non-destructive testing; Temperature modelling; Flexibla vägkonstruktioner; Tung trafikbelastning; Instrumenterade teststräckor; Fältvalidering; Oförstörande provning; Termisk modellering; Building Materials; Byggnadsmaterial;

    Abstract : It is well established that both traffic-related loading and environmental conditions influence the structural behaviour of pavements. Pavement design methods aim to consider the effect of traffic loading and environmental variables on pavement structure, foresee their changes during the lifetime of the pavement and predict the resulting distresses and pavement life.

  7. 10. Absorption of Sound : On the effects of field interaction on absorber performance

    Author : Anna Färm; Mats Åbom; Ragnar Glav; Susann Boij; Gareth Bennett; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sound absorption; Porous absorbers; Bulk reaction; Local reaction; Boundary layer; Grazing flow; Temperature gradients; Surface impedance; Sound field; Pass-by noise; Vehicle and Maritime Engineering; Farkostteknik;

    Abstract : Environmental noise has for decades been a well known problem, especially in urban areas. As noise requirements for vehicles are sharpened, noise reducing concepts are needed in early design stages requiring accurate simulations to support the design. READ MORE
