2. 1. Position-matching and goal-directed reaching acuity of the upper limb in chronic neck pain : associations to self-rated characteristics

   Author : Jonas Sandlund; Mats Djupsjöbacka; Eugene Lyskov; Ronny Lorentzon; Alf Thorstensson; Umeå universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Neck pain; whiplash injuries; shoulder; proprioception; kinesthesis; vision; psychophysiology; somatosensory disorders; psychomotor performance; self assessment; Sports research; Idrottsforskning;

   Abstract : Neck-shoulder pain is common in the general population and causes individual suffering as well as large costs for the society. Despite substantial efforts, there is still a shortage of methods for objective diagnosis and effective rehabilitation of such disorders. Thus, there is a great need to develop and evaluate new methods for these purposes. READ MORE

4. 2. Visual influences on vestibular compensation and postural control

   Author : Anna Hafström; Lund näs- och halssjukdomar Öron-; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Otorhinolaryngology; audiology; auditive system and speech; Otorinolaryngologi; Medicin människa och djur ; Vestibular schwannoma; Alcohol intoxication.; Medicine human and vertebrates ; Vestibular deafferentation; Visual-vestibular interactions; Subjective visual horizontal and vertical; Visual dependence; Utriculus; Balance; Vision; audiologi; hörsel- och talorganen;

   Abstract : This thesis aimed to investigate visual-vestibular interactions in healthy subjects and in patients with a well defined unilateral vestibular lesion (vestibular schwannoma before and six months after translabyrinthine surgery). Visual information is particularly important for balance control during perturbed stance. READ MORE

   Abstract : Reduced independent mobility of blind and low-vision individuals (BLVIs) cause considerable societal cost, burden on relatives, and reduced quality of life for the individuals, including increased anxiety, depression symptoms, need of assistance, risk of falls, and mortality. Despite the numerous electronic travel aids proposed since at least the 1940’s, along with ever-advancing technology, the mobility issues persist. READ MORE

7. 5. Passive Aircraft Altitude Estimation using Computer Vision

   Author : Anders Moe; Gösta Granlund; Linköpings universitet; []
   Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : This thesis presents a number of methods to estimate 3D structures with a single translating camera. The camera is assumed to be calibrated and to have a known translation and rotation.Applications for aircraft altitude estimation and ground structure estimation ahead of the aircraft are discussed.
