This chapter presents an augmented-reality based therapeutic device designed to overcome gait problems associated with Parkinson's Disease (PD). A normal model of gait is proposed followed by a model of Parkinsonian gait with the goal of construction of a gait enabling therapeutic device. The fundamental underlying tenet of the model is that vision pathology is responsible for the majority of P...

PURPOSE HDR (60)Co system has recently been developed and utilized for brachytherapy in many countries outside of the U.S. as an alternative to (192)Ir. In addition, the AccuBoost(®) technique has been demonstrated to be a successful non-invasive image-guided breast brachytherapy treatment option. The goal of this project is to evaluate the possibility of utilizing the BEBIG HDR (60)Co system f...

The kernel of a polygon P is the set of all points that see the interior of P . It can be computed as the intersection of the halfplanes that are to the left of the edges of P . We present an O(log log n) time CRCW-PRAM algorithm using n/log log n processors to compute a representation of the kernel of P that allows to answer point containment and line intersection queries efficiently. Our appr...

Finding of two undescribed species, closely related to Eresiomera paradoxa (Schultze, 1917) in Liberia and the Democratic Repubic of Congo led the authors to revise the material available in the African Butterfly Reserarch Institute (ABRI), Nairobi. Examination of the material revealed that the placement of E. paradoxa and the related species neither in the genus Eresiomera Clench, 1965, nor in...

During a countrywide survey we assessed the prevalence of climatic droplet keratopathy (CDK) in a randomised sample of 2446 subjects representative of the population of the Republic of Djibouti. The investigation of the relationship between CDK and two diseases considered to be related to exposure to ultra-violet light--namely, exfoliation syndrome and cataract--was planned as a case control st...

We present results from our analysis of F160W NICMOS Parallel images. These data cover ∼ 9 sq. arcminutes and reach 3σ depths of H= 24.3 − 25.5 in a 0.6 ′′ diameter aperture with integration times of 2,000 to 13,000 seconds. We derive the first deep H band galaxy counts. The slope of the counts for H< 20 is 0.31, consistent with various K-band measurements from the Keck telescopes. The measured...

As an important part of road transportation, bridge engineering plays a pivotal role in infrastructure construction. The wind field characteristics the site area have essential influence on both construction and operation period bridge, especially mountainous canyon terrain. In this paper, numerical simulation using computational fluid dynamics software was conducted to examine intricate region...
