Photogrammetry Analysis Direct
2015/6/1
Image resampling according to epipolar geometry is a prerequisite for a variety of photogrammetric tasks such as image matching,
DEM and ortho-photo generation, aerial triangulation, map compilation...
Random values of the cosmological constant
The universe physical parameters the cosmological constant
2014/12/22
Abstract One way that an anthropic selection mechanism may be manifest in a physical theory involves multiple domains in the universe with different values of the physical parameters. If this mechanis...
Spatial and temporal gradients in the cosmological constant
Basic physical parameters the universe physical parameters space
2014/12/20
It is possible that there may be differences in the fundamental physical parameters from one side of the observed universe to the other. I show that the cosmological constant is likely to be the most ...
A Relationship between the Comoving Particle Number and the Effective Cosmological Constant
Comoving Particle Number the Effective Cosmological Constant General Physics
2012/5/28
In order to discuss and obtain the remaining inflaton potential, we introduced an idea called "effective static friction" in our last paper to balance the "force", $\frac{dV}{d\phi}|_{\phi=\phi(t_{res...
Exact Analytic Solutions for the Rotation of an Axially Symmetric Rigid Body Subjected to a Constant Torque
Exact Analytic Solutions Rotation Axially Symmetric Rigid Body Constant Torque
2012/4/24
New exact analytic solutions are introduced for the rotational motion of a rigid body having two equal principal moments of inertia and subjected to an external torque which is constant in magnitude. ...

2012/4/24
The exact analytic solution is introduced for the rotational motion of a rigid body having three equal principal moments of inertia and subjected to an external torque vector which is constant for an ...
As proposed in a previous paper, the decorations of ancient objects can provide some information on the approximate evaluations of constant {\pi}, the ratio of circumference to diameter. Here we discu...

We study electronic transitions in highly-charged Cf ions that are within the frequency range of optical lasers and have very high sensitivity to potential variations in the fine-structure constant, a...
Constant curvature solutions of Grassmannian sigma models: (1) Holomorphic solutions
Sigma models Mathematical Physics Holomorphic solutions
2012/4/18
We present a general formula for the Gaussian curvature of curved holomorphic 2-spheres in Grassmannian manifolds G(m, n). We then show how to construct such solutions with constant curvature. We also...
Scaling laws for the non-linear coupling constant of a Bose-Einstein condensate at the threshold of delocalization
Scaling laws the non-linear coupling constant Bose-Einstein condensate threshold of delocalization
2012/2/28
We explore the localization of a quasi-one-, quasi-two-, and three-dimensional ultra-cold gas by a finite-range defect along the corresponding 'free'-direction/s. The time-independent non-linear Schro...
