Simplifying Loop Invariant Generation Using Splitter Predicates
Static analysis invariant generation decomposition of multiphase loops
2016/5/24
We present a novel static analysis technique that substantially improves the quality of invariants inferred by standard loop invariant generation techniques. Our technique decomposes multi-phase loops...
Suppression of vortex-induced forces on a two-dimensional circular cylinder by a short and thin splitter plate interference
circular cylinder splitter plate interference
2015/6/23
This paper briefly reviews bluff body aerodynamics and focuses mainly on
the use of short and thin splitter plates to interfere with the vortex wakes and
suppress vortex-induced forces (VIF). The ...
Binary Phase Micro-Grating and Polarization Beam Splitter for Free-Space Micro Optical Pickups
2011/11/24
A pop-up binary-phase micrograting and a pop-up micro polarization beamsplitter, for potential use in micro-optical pickups, have been realized on a single silicon chip using a two-layer polysilicon a...
Effective Accommodation for Users Located in Long / Short Distance Areas through PONs with Dual Stage Splitter Configuration Using ALC Burst-Mode Optical Amplifier
Long / Short Distance Areas Dual Stage Splitter Configuration Burst-Mode Optical Amplifier
2015/5/18
An ALC circuit that comprises our burst-mode optical amplifier suppresses the ASE noise in the time slots assigned to short-distance area and provides effective coexistence between long and short dist...
A new optical fiber line testing function for service construction work that checks for optical filters below an optical splitter in a PON
Fiber measurements Fiber Bragg gratings
2015/6/5
We propose a new function for construction-work undertaken to install optical cables for services in PONs. We demonstrated to determine whether an optical fiber is “live” or “unused”in branched fiber-...
Simulation and design of a wideband T-shaped photonic crystal splitter
photonic crystal photonic band gap beam splitter T-junction finite difference time
2011/5/9
In this paper, a high efficiency 2-D T-shaped photonic crystal beam splitter is proposed. It consists
of a square lattice of GaAs rods (n = 3.4) embedded in air. The photonic crystal structure
propo...
Numerical optimization of polarizing beam splitter gratings and modal explanation
diffractive optics rigorous coupled-wave analysis modal method polarizing beam splitter
2011/5/6
We describe high-density deep-etched fused-silica transmission polarizing beam splitter (PBS)
gratings and their simple physical explanation. Optimized numerical results of the grating depth
and per...
Three-Dimensional Low-loss Waveguide Shuffler and Splitter / Combiner using Novel Mirror Structure
Waveguide Shuffler Splitter / Combiner Mirror Structure
2015/7/17
We present 3D low-loss optical waveguide shuffler and splitter/combiner which will become important for high-channel count optical interconnect. We used a couple of TIR mirrors at a shuffling point an...
New technique and technology of industrial splitting of stacked wood ?log-splitter WS 800
wood splitter wedge splitting knife technology efficiency
2014/2/28
Wood splitting, manual as well as mechanized one is a heavy work. It follows from the fact that usually the wood of the least quality, knot wood with scroll fibres, directed for less valuable assortme...

Polarization Beam Splitter Two-Dimensional Triangular Photonic Crystals
2015/8/11
A design of a polarization beam splitter (PBS) in two-dimensional triangular photonic crystals is proposed and numerically demonstrated, for the rst time to our knowledge. The principle of the model ...
