We prove some results related to the generalized star-height problem. In this problem, as opposed to the restricted star-height problem, complementation is considered as a basic operator. We first show that the class of languages of star-height ≤ n is closed under certain operations (left and right quotients, inverse alphabetic morphisms, injective star-free substitutions). It is known that lan...

For years limited Monte Carlo simulations have led to the suspicion that the time to failure of hierarchically organized load-transfer models of fracture is nonzero for sets of infinite size. This fact could have profound significance in engineering practice and also in geophysics. Here, we develop an exact algebraic iterative method to compute the successive time intervals for individual break...

In this work we propose a method for securing port facilities which uses a set of video cameras to automatically detect various vessel classes moving within buffer zones and off-limit areas. Vessels are detected by an edge-enhanced spatiotemporal optimal trade-off maximum average correlation height filter which is capable of discriminating between vessel classes while allowing for intra-class v...

This is an announcement of some new computational methods in stable homotopy theory, in particular, methods for using the cohomology of small-height Morava stabilizer groups to compute the cohomology of large-height Morava stabilizer groups. As an application, the cohomology of the height four Morava stabilizer group is computed at large primes (its rank turns out to be 3440). Consequently we a...

The tree-layout problem is to compute the coordinates of nodes of a tree so that the tree, when drawn on a piece of paper, appeals to human understanding. The tree-layout problem, which seems inherently sequential at the first glance, can be solved with a data-parallel algorithm. It takes O (height * log width ) time on width processors when proper communication links between processors are ava...

Sport specific training in basketball players should focus on vertical jump height and agility in consistent with demands of the sport. Since plyometrics training improves vertical jump height and agility, it can be useful training strategy to improve the performance of basketball players. A convenience sample of thirty professional basketball players were recruited. Following pre-intervention ...

This study presents the biometric relationships among various increments that is useful in both scientific and practical terms for silvicultural of silver fir. The recorded characteristics trees are a faithful indicator effect work measures environmental conditions. Knowing these increments, them, can contribute to adaptations on stands with purpose reducing risks generated by factors. We carri...
