  2. 16. Competing Under Pressure : State Anxiety, Sports Performance and Assessment

    Author : Carolina Lundqvist; Peter Hassmén; Andrew Lane; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; competition; intra-individual variability; directional interpretations; emotions; sports performance; CSAI-2; psychometrics; Psychology; Psykologi; Samhällsvetenskap Humaniora;

    Abstract : Elevated levels of anxiety are a common response to stressful competitive sports situations, are known to moderate athletic performance and are referred to as an unpleasant emotional state associated with perceptions of situational threat. The empirical studies in this dissertation considered primarily psychometric, methodological and conceptual issues of relevance for the study of anxiety and sports performance. READ MORE

  4. 17. Sensing the environment : development of monitoring aids for persons with profound deafness or deafblindness

    Author : Parivash Ranjbar; Dag Stranneby; Erik Borg; Charlotte M. Reed; Örebro universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Auditive identification; Deaf; Deafblind; Directional perception; Environmental sound; Filtering; Frequency transposing; Hearing aid; Hearing impairment; Modulating; Monitoring; Tactile perception; Vibratory aid; Vibratory identification; Electronics; Elektronik; TECHNOLOGY; TEKNIKVETENSKAP; Elektronik; Electronics;

    Abstract : Earlier studies of persons with deafness (D) and/or deafblindness (DB) have primarily focused on the mobility and communication problems. The purpose of the present study was to develop technology for monitoring aids to improve the ability of persons with D and/or DB to detect, identify, and perceive direction of events that produce sounds in their surroundings.

  5. 18. Design, fabrication and characterization of plasmonic components based on silicon nanowire platform

    Author : Fei Lou; Lech Wosinski; Lars Thylén; Sebastian Lourdudoss; Anatoly Zayats; KTH; []
    Keywords : Planar integrated circuit; silicon photonics; plasmonics; subwavelength; directional coupler; polarization beam splitter; disk resonator; ring resonator; finite-difference time-domain; photonic crystal; electro-optic polymer; Purcell factor.;

    Abstract : Optical interconnects based on CMOS compatible photonic integrated circuits are regarded as a promising technique to tackle the issues traditional electronics faces, such as limited bandwidth, latency, vast energy consumption and so on. In recent years, plasmonic integrated components have gained great attentions due to the properties of nano-scale confinement, which may potentially bridge the size mismatch between photonic and electronic circuits.
