Similarly to β-adic van der Corput sequences, abstract van der Corput sequences can be defined by abstract numeration systems. Under some assumptions, these sequences are low discrepancy sequences. The discrepancy function is computed explicitly, and the bounded remainder sets of the form [0, y) are characterized.

BACKGROUND To evaluate skeletal and dentoalveolar effects of Forsus fatigue resistant devices (FRD) and twin-block (TB) appliance in Class II malocclusion cases. MATERIALS AND METHODS Twenty young adult patients (age 13-17 years, overjet 6-10 mm) with a Class II division 1 malocclusion were randomly divided into two groups: group I included 10 patients treated with TB, Group II included 10 pa...

field saturated hydraulic conductivity (kfs) is one of the most important soil properties that considerably contribute to soil quality. however, specifically in the structured soils, the measurement of kfs is difficult and time-consuming. therefore, verifying the simple and fast methods for kfs measurement is needed for effective soil monitoring. this study was conducted to investigate the effe...

Many problems of practical interest can be solved using tree search methods because carefully tuned successor ordering heuristics guide the search toward regions of the space that are likely to contain solutions. For some problems, the heuristics often lead directly to a solution| but not always. Limited discrepancy search addresses the problem of what to do when the heuristics fail. Our intuit...

We investigate a game played on a hypergraph H = (V,E) by two players, Balancer and Unbalancer. They select one element of the vertex set V alternately until all vertices are selected. Balancer wins if at the end of the game all edges e ∈ E are roughly equally distributed between the two players. We give a polynomial time ∗Research supported in part by a USA-Israel BSF grant, by the Israel Scie...
