Due to its lightweight encoder architecture, the Distributed Video Coding (DVC) concept has been seen as an attractive alternative to its conventional counterparts for a number of applications. Exceptionally low computational complexity has been achieved by moving redundancy exploitation to the decoder. However, going against this norm, redundancy exploitation techniques such as DCT transform a...

This paper presents an existence proof for modulating pulse solutions to a wide class of quadratic quasilinear Klein-Gordon equations of the form ∂ t u = ∂ 2 xu− u+ f1(u, ∂xu, ∂tu)∂ xu+ f2(u, ∂xu, ∂tu). Modulating pulse solutions consist of a pulse-like envelope advancing in the laboratory frame andmodulating an underlying wave-train; they are also referred to as ‘moving breathers’ since they a...

This paper presents a human-robot interface system that enables a user to move a robot by moving his hand. It adopts the technique of the 3D measurement based on the affine invariants from multiple views. In this system, we can choose a reference frame to obtain the 3D hand motion between the user-centered frame and the world-fixed frame. With the former frame, the system interprets the user's ...

People often use spatial language to talk about time, and this is known to both reflect and shape how they think about it. Despite much research on the spatial grounding of temporal language and thought, little attention has been given to how spatial metaphors influence reasoning about real events, especially those in the future. In a large online study (N=2362), we framed a discussion of clima...

This work focuses on the study of phenomenon vortex-induced vibrations in overhead lines under effect weak winds. Full three-dimensional simulation is not feasible because high length to width aspect ratios lines. Thus a quasi-3D method based strip theory adopted this work. decouples system interactions between line and wind into series sub-systems. The fluid flow each sub-system represented as...

Q. Does the Lorentz transformation reduce to the Galilean transformation when the ratio v /c is small? A. No. At least two routes are available to substantiate the negative response. I will first give a direct, algebraic route and then a more sophisticated indirect route. Consider the usual pair of inertial reference frames, the primed frame moving with speed v along the x axis of the unprimed ...

We used a variation of the generalized scidar (scintillation detection and ranging) technique to examine the temporal coherence of turbulent patterns at different altitudes in the atmosphere above Palomar Observatory. This enables us to test the validity of a frozen turbulence hypothesis in the local reference frame of the moving atmosphere. The data set analyzed here contains three turbulent p...

In the present investigation we have studied the peristaltic flow of a couple stress fluid in a non-uniform rectangular duct. The flow is investigated in a wave frame of reference moving with the velocity c away from the fixed frame. The peristaltic waves propagating on the horizontal side walls of a non-uniform rectangular duct is studied under lubrication approach. The exact solutions of velo...

[1] Plate tectonics constitutes our primary framework for understanding how the Earth works over geological timescales. High-resolution mapping of relative plate motions based on marine geophysical data has followed the discovery of geomagnetic reversals, mid-ocean ridges, transform faults, and seafloor spreading, cementing the plate tectonic paradigm. However, so-called ‘‘absolute plate motion...

The distinction between the real positions of moving objects in a single reference frame and the apparent positions of objects at rest in one inertial frame and viewed from another, as predicted by the space-time Lorentz Transformations, is discussed. It is found that in the Rockets-and-String paradox the string remains unstressed and does not break and that the pole in the Barn-and-Pole parado...
