   Sammanfattning : Tactile perception is considered an important contributor to the overall consumer experience of a product. However, what physical properties that create the specifics of tactile perception, are still not completely understood. LÄS MER

3. 2. AURALIZATION, PERCEPTION AND DETECTION OF TYRE–ROAD NOISE

   Författare :Alice Hoffmann; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Perception; Psychoacoustics; Rolling Noise; Traffic Detection; Reaction Time; Auralization; Tyre Road Noise;

   Sammanfattning : Due to improvements in combustion engines and electric engines for cars, tyre noise has become the prominent noise source at low and medium speeds. Models exist that simulate the noise produced by a rolling tyre, as do models that auralize specific traffic situations from a basic data set. LÄS MER

4. 3. La perception du français oral par des apprenants suédois

   Författare :Monika Stridfeldt; Barbro Nilsson; Ingmarie Mellenius; Paul Touati; Chantal Lyche; Umeå universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; French language; perception de la parole; reconnaissance des mots; français oral; acquisition de L2; apprenants de français; processus phonologiques; effacement du schwa; liaison; enchaînement; assimilation de sonorité; Franska; French language; Franska språket; Linguistics; lingvistik;

   Sammanfattning : Swedish learners of French often experience large difficulties in understanding spoken French. Words that the learners know very well when written or when pronounced separately are often hard to recognize in the speech flow. The aim of this study is to examine Swedish learners’ perception of French speech in order to identify the problems. LÄS MER

5. 4. A Model of Driver Perception and Action in Intersections

   Författare :Anna Bjelkemyr; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; intersection; vehicle heading; driving; behavior; driver; perception; eye movement; anticipate;

   Sammanfattning : The objective of the research presented in this thesis is to describe driver behavior while approaching, entering and exiting an intersection. To fulfill this objective, two semi-naturalistic studies were conducted where ten driver participants drove a test vehicle through a three-way intersection repeatedly, driving straight, turning left, and turning right in a total of six possible passes.

7. 5. 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
