This paper presents the conception, design, implementation and testing of innovative software architectures and software development processes for rapid prototyping of automated transit buses. Our work is motivated by demonstrations of automated transit bus technology in the context of Bus Rapid Transit (BRT) systems. Mission handling and safety issues are handled via a three-layer hierarchical...

assessment of colonic transit time (ctt) in patients with chronic constipation

n-ary transit functions are introduced as a generalization of binary (2-ary) transit functions. We show that they can be associated with convexities in natural way and discuss the Steiner convexity as a natural n-ary generalization of geodesicaly convexity. Furthermore, we generalize the betweenness axioms to n-ary transit functions and discuss the connectivity conditions for underlying hypergr...

Transit timing variations (TTVs) can provide useful information for systems observed by transit, as they allow us to put constraints on the masses and eccentricities of planets, or even constrain existence non-transiting companions. However, TTVs also act a detection bias that prevent small planets in transit surveys would otherwise be detected standard algorithms such Boxed Least Square algori...

TO THE EDITOR: We read with great interest the review article entitled " How to interpret a functional or motility test: colon transit study " by Kim et al. 1 The authors reviewed colonic transit study using radio-opaque markers, scintigraphy and wireless mo-tility capsule in evaluation of colonic motility. 1 They described the method and criteria to differentiate between slow and normal transi...

Planning new transit routes and refining existing routes often requires the calculation of the transit dependant socio-economic characteristics of potential passengers. The most common method used to derive the social profile for potential passengers is to create buffers around the transit routes and use Census data collected by the statistics bureau, which in this case is the Australian Bureau...

Background/Aims Esophageal dysmotility is associated with gastrointestinal dysmotility in various systemic and neuroregulatory disorders. Hypothyroidism has been reported to be associated with impaired motor function in esophagus due to accumulation of glycosaminoglycan hyaluronic acid in its soft tissues, leading to changes in various contraction and relaxation parameters of esophagus, particu...

Urban transit (bus and rail) operators, totaling nearly 700,000 persons, are one of the heaviest occupational groups in the United States (US). Little is known about occupational risk factors for weight gain and obesity and their interrelationship with health-related behaviors, particularly among female minority (African Americans and Hispanics) transit operators who are at greater risk for obe...
