In this note a new measure of irregularity of a simple undirected graph G is introduced. It is named the total irregularity of a graph and is defined as irrt(G) = 1 2 ∑ u,v∈V (G) |dG(u)− dG(v)| , where dG(u) denotes the degree of a vertex u ∈ V (G). The graphs with maximal total irregularity are determined. It is also shown that among all trees of same order the star graph has the maximal total...

This paper describes the demonstration of a regional high-resolution level-3 (L3) altimeter data unification and combination system (DUACS) developed with support from French space agency (CNES). Deduced full-rate (20 Hz to 40 Hz) level-2 (L2) measurements, this product provides sea level anomalies (SLA) other essential physical variables at spatial resolution one sample every ~1 km over North ...

The dynamic response of a hypersonic rocket sled was studied by considering the time-varying friction coefficient and gap caused wear between slipper track. A multibody model for system established mass moment inertia, nonlinear aerodynamic loads, engine thrust, track irregularity, contact force. As calculation, ductile shear criteria were used as material damage criteria, determined number dam...

Photobiomodulation is used to accelerate tooth movement during orthodontic treatments. The changes in root morphology in a group of orthodontic patients who received photobiomodulation were evaluated using the cone beam computed tomography technique. The device used is called OrthoPulse, which produces low levels of light with a near infrared wavelength of 850 nm and an intensity of 60 mW/cm(2)...

Irregularity of firing in spike trains has been associated with coding processes and information transfer or alternatively treated as noise. Previous studies of irregularity have mainly used the coefficient of variation (CV) of the interspike interval distribution. Proper estimation of CV requires a constant underlying firing rate, a condition that most experimental situations do not fulfill ei...
