The Haida plank house is one of the most important models built by native American Indians. Built on southwest coast Canada, it adapts tradition ancient pit houses to requirements humid and cold climate characteristic Gwaii Islands. This construction composed two main pieces: central covered a wooden envelope. Both protect its dwellers their hearths. ventilation system based solutions: gaps bet...

If a convex body K ? ?n is covered by the union of bodies C1, …, CN, multiple subadditivity questions can be asked. Two classical results regard width (the smallest distance between two parallel hyperplanes that sandwich K) and inradius largest radius ball contained in K): sum widths Ci at least (this plank theorem Thøger Bang), inradii due to Vladimir Kadets). We adapt existing proofs these pr...

A class of one-dimensional Fokker-Plank equations having a common stationary solution, which is a power function of the state of the process, was found. We prove that these equations also have generalized self-similar solutions which describe the temporary transition from one stationary state to another. The study was motivated by problems arising in mathematical modeling of genome size evolution.

Haptic interfaces using active force-feedback have mostly been used for emulating existing instruments and making conventional music. With the right speed, force, precision and software they can also be used to make new sounds and perhaps new music. The requirements are local microprocessors (for low-latency and high update rates), strategic sensors (for force as well as position), and non-line...

We present and formalize h, a core (or"plank") calculus that can serve as the foundation for several compiler specification languages, notably CRSX (Combinatory Reductions Systems with eXtensions), HACS (Higher-order Attribute Contraction Schemes), and TransScript. We discuss how the h typing and formation rules introduce the necessary restrictions to ensure that rewriting is well-defined, even...

The psychological contract was both conceptualised and has been investigated primarily in Western contexts. While research demonstrated its utility for exploring the nature of individual employment relationship other cultures, fundamental tenets have never challenged. In particular, there is an absence empirical on how notion implicit promises might be viewed Eastern contexts, spite constitutin...

CONTEXT Assessment techniques used to measure functional tasks involving active trunk control are restricted to linear movements that lack the explosive movements and dynamic tasks associated with activities of daily living and sport. Reliable clinical methods used to assess the diagonal and ballistic movements about the trunk are lacking. OBJECTIVE To assess the interday reliability of peak ...
