1. 41. Vibrations in timber floors : Dynamic properties and human perception

   Författare :Kirsi Jarnerö; Anders Professor; Tomi Toratti; Linnéuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wooden floor; timber floor; vibration; design criteria; damping; frequency; questionnaire; field test; socio-vibrational survey; vibration annoyance; vibration disturbance; Byggteknik; Civil engineering;

   Sammanfattning : Springiness and vibrations of timber floors are familiar to many as a ‘live’ feelwhen walking on them, especially if living in single family housing with timberframework. Since the building regulations in Sweden changed to performancedependentrequirements in 1994 the use of timber in multifamily housing hasincreased. LÄS MER

   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; sustainable recruitment; selection; police; general and crystallized intelligence; bifactor models; personality inventory; physical test; interviews; psychosocial working conditions; performance; job satisfaction; work related attitudes; health; hållbar rekrytering; urval; polis; generell begåvning; kristalliserad begåvning; bifaktormodeller; personlighetstest; fysiska test; intervjuer; arbetsmiljöfaktorer; prestation; arbetstillfredsställelse; arbetsrelaterade attityder; hälsa; Psychology; psykologi;

   Sammanfattning : Organisationer behöver kvalificerad personal för att fungera effektivt och därmed blir rekrytering en viktig aktivitet. Det är också angeläget att ny personal anpassar sig väl till arbetsförhållandena. LÄS MER

4. 43. Grouting of Fractured Rock with Silica Sol; Grouting design based on penetration length

   Författare :Johan Funehag; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Grouting; hydraulic test; sand column; propagation; penetration length; pipe flow; aperture; transmissivity; colloidal silica; silica sol; rheology; gelling liquids; field study;

   Sammanfattning : ABSTRACTRecent grouting projects in Sweden have concentrated on the grout itself. The only grout normally used in Sweden is cement-based. During the past 10 years, the acceptable flow of water into tunnels has been reduced significantly. The current requirements mean that an average fracture aperture of around 0. LÄS MER

5. 44. User engagement in Living Labs : Issues and concerns

   Författare :Abdolrasoul Habibipour; Anna Ståhlbröst; Diana Chronéer; John Sören Pettersson; Luleå tekniska universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; participatory design; user engagement; user engagement framework; user perspective; commitment; living lab; innovation; test; adoption; Information systems; Informationssystem;

   Sammanfattning : User engagement and the participatory design approach are well-established in information systems research for many years, and several studies have investigated the challenges of user engagement in the innovation processes. The majority of these studies have discussed participatory design activities – specifically user engagement –in an organizational context. LÄS MER

7. 45. Characterization and Design Requirements for Antennas in the Near-field and the Random-LOS Propagation Environment

   Författare :Aidin Razavi; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polarization-MIMO; Random-LOS; OTA; Antenna measurements; near-field antennas; antenna characterization; MIMO; near-field focusing;

   Sammanfattning : The choice of antenna for a particular application depends on the requirements imposed by that application. These can be, the application's field region (i.e., near-field or far-field), polarization, radiation pattern, radiation efficiency, system throughput, etc. LÄS MER
