  1. 11. Human Detection and Tracking with UWB radar

    Författare :Melika Hozhabri; Maria Lindén; Nikola Petrovic; Martin Ekström; Robin Augustine; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; UWB radar; signal processing; human detection; elektronik; Electronics;

    Sammanfattning : As robots and automated machineries are increasingly replacing the manual operations, protecting humans who are working in collaboration with these machines is becoming an increasingly important task. Technologies such as cameras, infra-red and seismic sensors as well as radar systems are used for presence detection and localization of human beings. LÄS MER

  3. 12. Hemmet och världen. Rumsliga perspektiv på medieanvändning

    Författare :Magnus Andersson; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; medieanvändning; rumslighet; geografi; rumslig praktik; hemmets väggar; Mediekonsumtion;

    Sammanfattning : I Hemmet och världen studeras de rumsliga aspekterna av mediernas närvaro i människors vardagsliv. Med geografisk utgångspunkt i hemmet och världen argumenteras för att meideanvändningen är en rumslig praktik i flera bemärkelser. För det första används medier för att markera och manifestera hemmet; medier som hemmets väggar. LÄS MER

  4. 13. On-line Mobile in situ Gamma Spectrometry

    Författare :Thomas Hjerpe; Lund Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiobiologi; Kärnfysik; Nuclear physics; radiation protection.; 137Cs; peak-to-valley method; depth distribution; orphan source search; orphan sources; emergency preparedness; mobile gamma spectrometry; nuclear accidents; Nuclear medicine; radiobiology; Nukleärmedicin;

    Sammanfattning : Mobile in situ gamma spectrometry is an important instrument in the emergency preparedness for nuclear accidents. This work contributes through the development of strategies and analysis methods for two applications: an on-line search for gamma-emitting orphan sources and on-line estimation of the depth distribution of 137Cs.

  5. 14. Temporal Distance and Morality : Moral Concerns Loom Larger in the Distant Future

    Författare :Jens Agerström; Institutionen för psykologi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; moral concerns; morality; moral judgment; Construal Level Theory; temporal distance; moral reasoning;

    Sammanfattning : The aim of this dissertation was to examine whether the temporal distance of moral events affects the moral judgments and decisions people make in response to those events. Drawing upon Construal Level Theory (CLT; Trope & Liberman, 2003) which posits that the distant future is represented at a higher, more abstract level of mental construal than the near future, and that high-level mental construals shift attention to core values and higher-order principles, the main proposition of this dissertation was that people would show greater moral concerns in response to distant future events than near future events.

  7. 15. Experimental and Theoretical Study of Rack Storage Fires

    Författare :Haukur Ingason; Avdelningen för Brandteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; response time; in-rack sprinkler; flame heat transfer; gas velocity; gas temperature; flame height; in-rack fire plume; Rack storage fire; fire growth rate; Technological sciences; Teknik;

    Sammanfattning : A theoretical and experimental study of rack storage fires and responsiveness of sprinklers is presented. Free-burn tests with non-combustible and combustible material were carried out in reduced scale with verification in large scale. LÄS MER
