The model of West, Brown and Enquist showed that total hydraulic resistance in trees can be independent of path length, provided that vascular conduits taper sufficiently. This model assumes that the tree branch network is volume-filling, so that segment lengths increase exponentially from tree top to base. We show that partial buffering of hydraulic resistance from path-length effects can occu...

The forming limitation and the wall thickness distributions are two main parameters for estimating quality of T-shaped tubes. In this paper, effects three key factors on investigated, which punch front distance l1, reverse height h1, matching relationship between rubber hardness axial feed ?l. A new position-limited backpressure mechanism is proposed, made up rigid lever, flexible medium, space...

In [1] the occurence of a Hopf bifurcation at steady-state cornering for two-wheel oversteering vehicle with brush model tyre forces was found and following bifurcating branch periodic solutions we observed Canard phenomenon relaxation oscillations, which are typical singularly perturbed systems. that article assumed simplicity, car's center mass lies street level. this presentation investigate...

This paper presents a treegion-based global scheduling technique for wide issue VLIW/EPIC processors. A treegion is a single-entry/multiple-exit global scheduling scope that consists of basic blocks with control-flow forming a tree. We propose a two-phase approach to global scheduling within a treegion scope that enables speculative code motion in the first phase and uses predication of all ins...

The lateral femoral cutaneous nerve (LFCN) is a sensitive collateral branch of the lumbar plexus that innervates the anterolateral region of the thigh. Its compression at the level of the groin originates a particular syndrome called meralgia paresthetica. Treatment of this neuropathy may involve sectioning or freeing of the nerve, both of which require an appropriate knowledge of its anatomy. ...

2000 plant canopy analyzer measured changes in leaf area index (LAI) and plant area index (PAI) in a 25-year-old Scots pine (Pinus sylvestris L.) stand. Stand density was 2100 stems ha and mean tree height was 8.7 m. Needle and branch areas of the stand were reduced progressively to zero by the stepwise removal of branches on all trees growing in a circular plot with a radius of 25 m. An LAI-20...

We present space-efficient parallel strategies for two fundamental combinatorial search problems, namely, backtrack search and branch-and-bound, both involving the visit of an n-node tree of height h under the assumption that a node can be accessed only through its father or its children. For both problems we propose efficient algorithms that run on a distributed-memory machine with p processor...
