We describe approaches for distances between pairs of two-dimensional surfaces (embedded in three-dimensional space) that use local structures and global information contained in interstructure geometric relationships. We present algorithms to automatically determine these distances as well as geometric correspondences. This approach is motivated by the(More)
We discuss monolithic integration of a 100-channel AWG with a 10-GHz channel spacing with 100 Michelson-interferometer-based phase-and amplitude-modulators. The AWG showed approximately 10 dB crosstalk, and the twin-integrated devices comprise a 2 " InP wafer. 1. Introduction Optical arbitrary waveform generation (OAWG) has potential applications such as:(More)
We demonstrate monolithic integration of a 100-channel arrayed-waveguide grating (AWG) with 10-GHz channel spacing and 100 optically controlled Michelson-interferometer-based phase and amplitude modulators. The high-resolution AWG showed better than À15-dB crosstalk, and the modulator extinction ratio was better than 20 dB with either electrical or optical(More)
—We report a 10-GHz colliding pulse mode-locked laser fabricated with integrated active–passive waveguides. The laser fabrication adopted a deep reactive ion etching and single-step metal–organic vapor phase epitaxy regrowth process for forming the buried heterostructure waveguide. Clean output pulses resulted from laterally tilting the active–passive(More)
The objective of the current study was to develop a validated stability-indicating assay method (SIAM) for risperidone after subjecting it to forced decomposition under hydrolysis, oxidation, photolysis, and thermal stress conditions. The liquid chromatographic separation was achieved isocratically on a symmetry C18 column (5 μm size, 250 mm × 4.6 mm i.d.)(More)
We overview and summarize the progress of the spectral phase encoded time spreading (SPECTS) optical code division multiple access (O-CDMA) technology. Recent progress included a demonstration of a 320 Gbit/ s ͑32-user ϫ 10 Gbit/ s͒ all-optical passive optical network testbed based on the SPECTS O-CDMA technology and a theoretical prediction of the spectral(More)
This paper presents a loss minimization algorithm (LMA) based nonlinear controller for high-performance and highly efficient interior permanent magnet synchronous motor (IPMSM) drive. Among numerous LMAS a loss model-based controller (LMC) approach offers a fast response without torque pulsations. However, a difficulty in deriving the LMC lies in the(More)
Reactive oxygen and nitrogen species (ROS/RNS) have been widely implicated in the ageing process and various approaches exist for monitoring these species in biological tissues. These approaches at present are limited to monitoring either a single pro-oxidant species or total pro-oxidant levels and therefore provide limited insight into the range of(More)
Zonisamide is a benzisoxazole derivative, used as an adjunctive antiepileptic in the treatment of partial seizure. A Simple, economic, reproducible & precise spectroscopic method has been developed for estimation of Zonisamide in bulk and pharmaceutical dosage form. Estimation was carried out at λ max 240nm using methanol as solvent in stock solution and(More)
Wsn Formed by hundreds or thousands of heterogeneous sensor node (motes) devices spread over large field that share or exchange information with each other and move data along from one to another nodes. But in reality, these wireless networks are composed of resource constrained tiny sensor nodes. The resource constrained nature of WSN creates different(More)
