You’ve seen Bear Grylls turn foul water into drinking water with little more than sunlight and plastic.Now, academics have added a third element — carbon-dipped paper — that may turn this survival tac...
Spacetime and Reality:Facing the Ultimate Judge
Minkowski absolute world spacetime relativity of simultaneity length contraction
2016/5/31
Over a hundred years ago in his paper "Space and Time" Hermann Minkowski demonstrated the profound meaning of the relativity postulate - the experimental fact that physical phenomena are the same in a...
An Ultimate Transposition Cipher (UTC) is defined as a cipher that transposes any permutation of some n elements to any other permutation of the same elements. Hence, by listing together the protected...
Finding ultimate limits of performance for hybrid electric vehicles
Fuel nonlinear convex optimization large linear programming
2015/8/11
We formulate the problem of optimizing fuel efficiency as a nonlinear convex optimization problem. This convex problem is then accurately approximated as a large linear program. As a result, we comput...

3D FE Analysis of Effect of Ground Subsidence and Piled Spacing on Ultimate Bearing Capacity of Piled Raft and Axial Force of Piles in Piled Raft
Ground Subsidence Piled Raft Piled Spacing Bearing Capacity Axial Force 3D FE Simulation
2013/1/31
The effects of ground subsidence and piled spacing on axial force of piles in squared piled rafts were investigated using numerical analysis. Two cases of piled rafts in soft clay including case 1 (s ...
Competition between electronic Kerr and free carrier effects in an ultimate-fast optically switched semiconductor microcavity
electronic Kerr free carrier effects semiconductor microcavity Optics
2012/5/17
We have performed ultrafast pump-probe experiments on a GaAs-AlAs microcavity with a resonance near 1300 nm in the "original" telecom band. We concentrate on ultimate-fast optical switching of the cav...
