   Abstract : Optical properties of semiconductor nanowires (NWs)/nanopillars (NPs), as individual or ensemble, have attracted significant research interest in recent years. Their potential applications range from solid-state lighting, photovoltaics, lasing and nonlinear optics to sensing and life sciences. READ MORE

5. 18. The Perception and Evaluation of Pleasant Touch and the Development of "Satiety" for Hedonic Tactile Experiences

   Author : Chantal Triscoli; Göteborgs universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Pleasant touch; CT afferents; Top-down mechanisms; Satiety; Liking; Wanting;

   Abstract : Pleasant touch is a hedonic experience and one of the most powerful means for social bonding and for communicating affection. Touch similar to a human caress is detected by the “C tactile (CT) afferents”, a class of mechanoreceptors which respond preferentially to stroking velocities between 1 and 10 cm/s. READ MORE

6. 19. Implementation of Flash Analog-to-Digital Converters in Silicon-on-Insulator Technology

   Author : Erik Säll; Mark Vesterbacka; Bengt E. Jonsson; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flash analog-to-digital converter; ADC; silicon-on-insulator; SOI; top-down design; dynamic element matching; DEM; thermometer-to-binary encoder; flash ADC modeling; Electronics; Elektronik;

   Abstract : High speed analog-to-digital converters (ADCs) used in, e.g., read channel and ultra wideband (UWB) applications are often based on a flash topology. The read channel applications is the intended application of this work, where a part of the work covers the design of two different types of 6-bit flash ADCs. READ MORE

7. 20. The conscious brain : Empirical investigations of the neural correlates of perceptual awareness

   Author : Johan Eriksson; Lars Nyberg; Geraint Rees; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; consciousness; visual perception; object identification; functional neuroimaging; top-down processing; prefrontal cortex; auditory perception; Neuroscience; Neurovetenskap;

   Abstract : Although consciousness has been studied since ancient time, how the brain implements consciousness is still considered a great mystery by most. This thesis investigates the neural correlates of consciousness by measuring brain activity with functional magnetic resonance imaging (fMRI) while specific contents of consciousness are defined and maintained in various experimental settings.
