This test is based on the incompressibility of myocardium, which dictates that left ventricular wall volume remains constant throughout the cardiac cycle. The volumes occupied by the left ventricular cavity, by ventricular wall plus cavity, and hence by ventricular wall alone were estimated, both at end-systole and at end-diastole, from ecocardiographic measurements of cavity transverse dimensi...

We continue our study of the statistical mechanics of a 2D surface above a xed wall and attracted towards it by means of a very weak positive magnetic eld h in the solid on solid (SOS) approximation, when the inverse temperature is very large. In particular we consider a Glauber dynamics for the above model and study the rate of approach to equilibrium in a large cube with arbitrary boundary co...

We give two fundamental solutions for the motion of a point vortex near a flexible wall, up to first order in wall deflection, using computational methods. For a point vortex near an infinite horizontal wall, the deformation of the wall intensifies the flow at the wall near the vortex, and increases the speed of the vortex. Near a circular wall there is a strong mutual amplification of the defl...

Considering grid requirements of high Reynolds flow, wall-modeled large eddy simulation (WMLES) and detached (DES) have become the main methods to deal with near-wall turbulence. However, flow separation phenomenon is a challenge. Three typical separated flows, including over cylinder at ReD = 3900 based on diameter, wall-mounted hump Rec 9.36 × 105 length, transonic an axisymmetric bump shock-...

In this work, the characteristics of incoming and wake flows downstream wall-mounted fences under wind gust were explored with tunnel experiments. A time-resolved particle image velocimetry was used to capture flow dynamics across two different fence heights. The results show that during period, presents distinct meandering strong mixing. Probability Density Function distribution velocities ind...

Space–time cube is often used as a visualization technique representing trajectories of moving objects in (geographic) space and time by three display dimensions (Hägerstrand 1970). Despite the recent advances allowing space–time cube visualization of clusters of trajectories, it is problematic to represent trajectory attributes. We propose a new time transformation—sequential ordering—that tra...

When Wireless Sensor Networks (WSNs) are deployed in a railway tunnel environment, the available deployment positions and equipment size are restricted by regulations from the infrastructure owners in order to maintain the loading gauge. As we have discovered in the Aldwych tunnel [1], antennas mounted near to the tunnel wall worsens the path loss (PL) performance at 868MHz and 2.45GHz. However...
