High-end computing and computational fluid dynamics (CFD) have played a key role in improving and enhancing Shuttle performance, reliability, and safety for more than two decades. The NASA Advanced Supercomputing (NAS) Division has been developing CFD-based highfidelity design and analysis tools, which are being employed to help analyze today’s problems, as well as guiding design decisions for ...

We analyze passenger count data from the Marguerite Shuttle system operating on the Stanford University campus. The aim is to infer the time-varying passenger alighting and boarding preference across stops for several important shuttle routes. We look at the problem from the perspective of filling in the missing entries of a transit route O-D matrix. A preliminary analysis indicates that there ...

We present a Mechatronics design approach and related technologies for a badminton playing robot, as a first stage of a multi-year project. The robot is using non-modified shuttles and rackets, which are detected and localized using purely visual information. The robot subsystems are presented: mechanical design, visual detection of the shuttle, shuttle trajectory estimation and interception, a...

4002bp, contained an AT-rich region and eneoded several open reading frfimes, as deduced by the comp]ete nucleotide sequence. One of the plltative open reading frames showed homology with replication proteins of other plasmids. A shuttle vector of Escherichia coti and this strain was constructed by connecting pAH4 to pUCI8. Electroporation of the shllttle vector into the strain yielded 1 .7 x 1...

Shuttle cars form a part of the standard equipment employed by the mining Industry In the transportation of coal when using the room-and-plller method for extracting coal from underground seams. These cars are subject to frequent failure, so the problem of assigning shuttle cars to sections of the mine is considered in this paper, with the objective of maximizing expected output. A particularly...

A novel shuttle integration cosmid vector (pTOYAMAcos), based on pKU402, and shuttle integration vectors (pTYM18 and pTYM19) were constructed for the cloning of actinomycete DNA and its heterologous expression. These vectors contain oriT of an IncP transmissible plasmid in order to transfer genes by conjugation from Escherichia coli to actinomycetes, and they also contain int derived from actin...

Background. Morbidity and mortality are higher in patients with poor preoperative cardiorespiratory reserve. This study aimed to ascertain fitness and therefore risk in elective patients, comparing three measures: Duke Activity Status Index (DASI) questionnaire, incremental shuttle walk test (ISWT), and cycle cardiopulmonary exercise testing (CPET). We looked for correlation between the measure...

In the heart, elevated thyroid hormone leads to upregulation of metabolic pathways associated with energy production and development of hypertrophy. The malate/aspartate shuttle, which transfers cytosolic-reducing equivalents into the cardiac mitochondria, is increased 33% in hyperthyroid rats. Within the shuttle, the aspartate-glutamate carrier is rate limiting. The excitatory amino acid trans...

OBJECTIVE To validate an incremental field walking test, the shuttle walking test, as a means of assessing pacing modes and to aid programming of rate responsive pacemakers. DESIGN Three separate groups of patients were recruited. Reproducibility (n = 10) of the shuttle walking test was assessed by performing three consecutive tests. Comparison of the shuttle walking test with a 10 min walk w...
