2. 1. Methods for Objective and Subjective Video Quality Assessment and for Speech Enhancement

   Author : Muhammad Shahid; Blekinge Tekniska Högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Video Quality Assessment; No-Reference Methods; Reduced-Reference Methods; Subjective Experiments; Speech Enhancement; Adaptive Gain Equalizer;

   Abstract : The overwhelming trend of the usage of multimedia services has raised the consumers' awareness about quality. Both service providers and consumers are interested in the delivered level of perceptual quality. The perceptual quality of an original video signal can get degraded due to compression and due to its transmission over a lossy network. READ MORE

4. 2. Assessment of crosswind performance of buses

   Author : Magnus Juhlin; Annika Stensson Trigell; Carsten Proppe; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; crosswind; buses; steering feel; directional stability; subjective; objective; aerodynamic load; Vehicle engineering; Farkostteknik;

   Abstract : When driving a vehicle on the road, the driver has to compensate continuously for small directional deviations from the desired course due to disturbances such as crosswinds, road irregularities and unintended driver inputs. These types of deviations have a tiring effect on the driver and should therefore be minimised. READ MORE

5. 3. Placebo, alcohol and flumazenil provocations : subjective and objective registrations in psychopharmacological experiments

   Author : Lars Saxon; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Abuse and dependency of alcohol or drugs is a major problem today, with severe implications for society as well as for the individual. Treatment is often characterised by hard work and the road to recovery is (among other problems) paved with acute and protracted withdrawal symptoms as well as relapse. READ MORE

6. 4. Low frequency noise during work. Effects on performance and annoyance

   Author : Johanna Bengtsson; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Low frequency noise; performance; workload; annoyance; cortisol; subjective stress; subjective sensitivity to noise; sound characteristics; frequency balance; modulation frequency;

   Abstract : Aims. Low frequency noise (LFN) is defined as "a noise with a dominant frequency content of 20 to 200 Hz". Common sources of LFN in occupational environments are ventilation, heating and air-conditioning systems, computer network installations and compressors. READ MORE

7. 5. Quality Inspection and Evaluation of Smart or Functional Textile Fabric Surface by Skin Contact Mechanics

   Author : Melkie Getnet Tadesse; Cristian Vasile; Högskolan i Borås; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tactile comfort; expert; subjective evalaution; objective evalaution; smart fabric; functional fabric; skin contact; KES; sensory evalaution; sensory perception;

   Abstract : The rapid progress in consuming e-textiles has made a huge uprising in the researcher’s track on the course of smart and functional textile development. Consumption of functional and smart textiles in the wearable e-textile is fetching extra eye-catching scheme owing to its lightweight property, flexibility, stretchability, and the ability to be integrated into wearable apparel.
