A power law describes the relationship between the geometric properties of a trajectory (radius of curvature) and movement kinematics (tangential velocity) in curved drawing movements. Although the power law is a general law of motion, there are conditions under which it degrades. In particular, the power law may be less explanatory of movements around certain joints. The present study consider...

We examine the coarse-grained phase-space density profiles of a set of recent, highresolution simulations of galaxy-sized Cold Dark Matter (CDM) halos. Over two and a half decades in radius the phase-space density closely follows a power-law, ρ/σ ∝ r−α, with α ≈ 1.875. This behaviour closely matches the self-similar solution obtained by Bertschinger for secondary infall of gas onto a point-mass...

In this paper, a hybrid solid oxide fuel cell (SOFC) and micro gas turbine (MGT) power system is parametrically studied to evaluate the effect of different operating conditions. The SOFC/MGT power system includes SOFC reactor, combustion chamber, compressor and turbine units, and two heat exchangers. The effects of fuel utilization, temperature, and pressure are assessed on performance of t...

In high energy p+p interactions the mean multiplicity of neutral mesons (from mη ∼= 0.55 GeV/c2 to mΥ ∼= 9.5 GeV/c2) and the transverse mass spectra of pions (mT = 1 ÷ 15 GeV/c2) reveal a remarkable universal behaviour: they follow, over 10 orders of magnitude, the same power law function: C · m (T ) . This scaling is rather similar to that expected in the statistical description of hadron prod...

in future high-speed self-routing photonic networks based on all-optical time division multiplexing (otdm) it is highly desirable to carry out packet switching, clock recovery and demultplexing in the optical domain in order to avoid the bottleneck due to the optoelectronics conversion. in this paper we propose a self-routing otdm node structure composed of an all-optical router and demultiplex...

We present two broadcast authentication protocols based on delayed key disclosure. Our protocols rely on symmetric-key cryptographic primitives and use cryptographic puzzles to provide efficient broadcast authentication in different application scenarios, including those with resource-constrained wireless devices such as sensor nodes. The strong points of the protocols proposed are that one all...

It made that the new symmetric property, the binary law, existed newly in our time and space at the thing except the symmetric property of the principle of general relativity which is already known in this paper clear. The introduction of this symmetric property will have made dealing with the position tensor of us handy as much as the surprise.
