Dedicated to the memory of Gerold Wagner Abstract We study the L w -norm (2 < W < oo) of the discrepancy of a sequence of points in the unit cube relative to similar copies of a given convex polygon. In particular, we prove the rather surprising result that the estimates obtained have the same order of magnitude as the analogous question when the sequence of points is replaced by a set of point...

Irregularities are inherent to virtually all fibers, including the conventional textile fibers, the high-performance brittle fibers and newly developed nano-fibers. These irregularities can fall into two main categories: dimensional or geometrical irregularity (external) and structural irregularity (internal). For natural fibers such as wool, diameter variation along fiber length is atypical ex...

background: polycystic ovarian syndrome (pcos) has been shown to cause a reduction in health-related quality of life (hrqol). objective:  this study examines the extent of different clinical symptoms in pcos patients on hrqol. materials and methods:  a cross-sectional study was undertaken to ascertain the factors related to hrqol in 200 pcos patients in kashan, iran. main outcome measures were ...

Many researchers have long observed some cases in which certain ranking irregularities can occur when the original analytic hierarchy process (AHP), or some of its variants, are used. This paper presents two new categories of ranking irregularities which defy common intuition. These ranking irregularities occur when one decomposes a decision problem into a set of smaller problems each defined o...

The Wide Area Augmentation System (WAAS) will provide real-time differential GPS corrections and integrity information for aircraft navigation use. The most stringent application of this system will be precision approach, where the system guides the aircraft to within a few hundred feet of the ground. Precision approach operations require the use of differential ionospheric corrections. WAAS mu...

We report on some recent advancements on the development of the ROADRUNNER system, which is able to automatically infer a wrapper for HTML pages. One of the major drawbacks of the ROADRUNNER approach was its limited ability in handling irregularities in the source pages. To overcome this issue, we have developed a technique to deal with chunks of unstructured HTML code. Several experiments have...

High speed trains are currently meant to run faster and to carry heavier loads, while being less energy consuming and still respecting the security and comfort certification criteria. To face these challenges, a better understanding of the interaction between the dynamic train behavior and the track geometry is needed. As during its lifecycle, the train faces a great variability of track condit...
