This paper presents an evaluation of flexural live-load distribution factors for a series of threespan prestressed concrete girder bridges. The response of one bridge, measured during a static live-load test, was used to evaluate the reliability of a finite-element model scheme. Twenty-four variations of this model were then used to evaluate the procedures(More)
A program package that can be used for analysis of a wide range of kinetic and equilibrium data is described. The four programs were written in Turbo Pascal and run on PC, XT, AT and compatibles. The first of the programs allows the user to fit data with 16 predefined and one user-defined function, using two different non-linear least-squares procedures.(More)
The Ca2+ antagonist mibefradil at supratherapeutic concentrations induced a sustained increase of cytosolic Ca2+ in cultured rat cardiac fibroblasts and human platelets which lack sensitivity to K+ depolarization and Ca2+ channel block by verapamil or other Ca2+ antagonists. At concentrations above 10 μM, mibefradil elevated substantially cytosolic [Ca2+](More)
Wireless Mesh Networks (WMNs) have emerged as a key technology for the next generation of wireless networking. Instead of being another type of ad-hoc networking, WMNs diversify the capabilities of ad-hoc networks. Several protocols that work over WMNs include IEEE 802.11a/b/g, 802.15, 802.16 and LTE-Advanced. To bring about a high throughput under varying(More)
One of the extraordinary aspects of nonlinear wave evolution which has been observed as the spontaneous occurrence of astonishing and statistically extraordinary amplitude wave is called rogue wave. We show that the eigenvalues of the associated equation of nonlinear Schrödinger equation are almost constant in the vicinity of rogue wave and we validate that(More)

Comparing the Poincare plots of the Tokamap and the underlying Hamiltonian system reveals large differences. This stems from the particular choice of evaluation of the singular perturbations present in the system (a series of delta functions). A symmetric evaluation approach is proposed and shown to yield results that almost perfectly match the Hamiltonian(More)
