Novel self-learning based crawling and data mining for automatic information extraction (2015)

In this paper, we propose techniques using a novel combination of self-learning based crawling and rule based data mining. Using the crawling techniques smaller relevant data sets can be obtained pertaining to a domain from multi-dimensional data sets available in on-line as well as off-line sources. We then process the crawled data sets and mine to extract meaningful information. Our techniques are generic in nature and can be used for automatic information extraction in different domains such as biomedical, health-care, enterprise infrastructure planning, etc. The proposed schemes are of reduced time, space and processor complexity due to the assisted and learning nature of the crawling. The data mining is based on configurable classification rules and decision trees, which are scalable and easy to implement in practice. We evaluate our proposed techniques through Java based implementation and integration with TCS in-house enterprise network design tool NetDes.
Both Family 1 and Family 2 PspA Proteins Can Inhibit Complement Deposition and Confer Virulence to a Capsular Serotype 3 Strain of <i>Streptococcus pneumoniae</i> (2002)

Pneumococcal surface protein A (PspA), a virulence factor of Streptococcus pneumoniae, is exceptionally diverse, being classified into two major families which are over 50% divergent by sequence analysis. A family 1 PspA from strain WU2 was previously shown to impede the clearance of pneumococci from mouse blood and to interfere with complement deposition on the bacterial surface. To determine whether a family 2 PspA can perform the same role as family 1 PspA, the family 1 PspA (from strain WU2) was replaced with a family 2 PspA (from strain TIGR4) by molecular genetic methods to make an isogenic pair of strains expressing different PspA proteins. Surface binding of lactoferrin and interference with C3 deposition by the two types of PspA proteins were determined by flow cytometry, and virulence was assessed in a mouse bacteremia model. Although the family 2 PspA appeared to bind less human lactoferrin than did the family 1 PspA, both PspA proteins could interfere with complement deposition on the pneumococcal surface and could provide full virulence in the mouse infection model. A mutant form of the family 2 PspA with a deletion within the choline-binding region was also produced. Pneumococci with this mutant PspA failed to bind human lactoferrin even though the PspA was present on the pneumococcal surface. The mutant PspA only partially interfered with complement deposition and moderately attenuated virulence. These results suggest that family 1 and family 2 PspA proteins play similar roles in virulence and that surface accessibility of PspA is important for their function.
Output power and efficiency sensitivity to circuit parameter variations in double-sided LCC-compensated wireless power transfer system (2015)

This paper focuses on the sensitivity of power transfer to parameter variations in a 5.7kW double-sided LCC-compensated wireless power transfer system. A SPICE model of the circuit component with parasitic resistance is built to accurately calculate the power loss and efficiency. LTspice software is used to simulate the system performance for different parameter combinations, which are generated by exhaustive and Monte-Carlo methods. It is shown that, in certain cases, the switching frequency can be adjusted to compensate for parameter variations. Finally, a 5.7kW WPT system is implemented, and experiments are performed at the parameter combination corresponding to the lowest and highest power. The comparison between simulation and experiment results demonstrates the presented sensitivity problem and the effectiveness of frequency adjusting method.

Molecular Cloning and Sequencing of Three Granulocytic<i>Ehrlichia</i>Genes Encoding High-Molecular-Weight Immunoreactive Proteins (1998)

Granulocytic Ehrlichia was isolated from canine blood obtained from animals challenged with field-collected Ixodes scapularis and propagated in HL60 cells. PCR primers specific for the 16S ribosomal DNA (rDNA) of the Ehrlichia genogroup comprising E. equi, E. phagocytophila, and the agent of human granulocytic ehrlichiosis (HGE) amplified DNA from extracts of these cells. Sequence analysis of this amplified DNA revealed that it is identical to the 16S rDNA sequence of the HGE agent. A genomic library was constructed with DNA from granulocytic Ehrlichia and screened with pooled sera from tick-challenged, granulocytic Ehrlichia-infected dogs. Several clones were isolated and sequenced. Three complete genes encoding proteins with apparent molecular masses of 100, 130, and 160 kDa were found. The recombinant proteins reacted with convalescent-phase sera from dogs and human patients recovering from HGE. This approach will be useful for identifying candidate diagnostic and vaccine antigens for granulocytic ehrlichiosis and aid in the classification of genogroup members.
New sampling and filtering approaches to label-free ultrasonic perfusion imaging (2018)

Color-flow and power Doppler imaging are safe, low-cost, non-invasive techniques for assessing blood flow throughout the body. Imaging microvascular flows and perfusion generally requires injectable contrast agents to separate tissue clutter from blood echoes. Our innovation is to modify echo acquisition to expand data dimensionality and increase sensitivity of non-enhanced PD imaging to very slow, disorganized flows. To separate perfusion from other echo signals, we developed a higher-order singular value decomposition filter that appropriately reduces data dimensionality. Effective elimination of clutter and noise results improved perfusion specificity. Our methods are applied to existing commercial US instruments, which makes them immediately valuable to medical practice. Our methods were previously tested at 24 MHz in a study involving muscle ischemia and highly-vascular melanoma lesions in mice. This study translates the methods to lower frequencies (5-10 MHz) for human trials. We developed a dialysis-cartridge device using TM-blood to quantifying very slow flow in the presence of tissue-like clutter and noise. We calibrated our technique to quantify the sensitivity, dynamic range, and spatial resolution of PD imaging. Results indicate an ability to separate flow speeds as low as 0.3 mm/s from clutter signals.
Flow Visualization within the Evaporator of Planar Loop Heat Pipe (2005)

A planar micro loop heat pipe (LHP) with coherent porous silicon (CPS) wick in the evaporator is a two‐phase heat transfer device that utilizes evaporation and condensation to transfer heat. This CPS wick has thousands of pores, which are 2 micrometer in diameter, contained over an area of one square centimeter. As heat is applied to the evaporator, liquid is vaporized and evaporator chamber’s pressure is increased. A meniscus formed at the liquid/vapor interface inside the pore of the CPS wick is supported by capillary forces even though pressure force pushes it down. Vapor flows through the vapor line to the condenser and condenses. Liquid is transported back to the evaporator due to pressure difference. The internal thermodynamics and fluid dynamics are poorly understood due to the difficulty of taking internal measurements and the complexity of two‐phase phenomena. To understand this thermal device, the clear evaporator machined from Pyrex glass was utilized to monitor the complex phenomena which occur in the evaporator. These phenomena include vapor formation, nucleate boiling, evaporation, depriming, and pressure oscillation. DI‐water was utilized as the working fluid.

Improved refractory coatings (1980)

The adhesion, friction and wear properties of sputtered refractory coatings on substrates of materials that form stable nitrides are enhanced by placing each substrate directly below a titanium carbide target of a commercial radiofrequency diode apparatus in a vacuum chamber. Nitrogen is bled into the system through a nozzle resulting in a small partial pressure of about 0.5% to 2.5% during the first two minutes of deposition. The flow of nitrogen is then stopped, and the sputtering ambient is reduced to pure argon through a nozzle without interrupting the sputtering process. When nitrogen is deliberately introduced during the crucial interface formation, some of the titanium at the interface reacts to form titanium nitride while the metal of the substrate also forms the nitride. These two nitrides atomically mixed together in the interfacial region act to more strongly bond the growing titanium carbide coating as it forms on the substrate.

The Application of Probabilistic Methods to the Mistuning Problem (2004)

FMM is a reduced order model for efficiently calculating the forced response of a mistuned bladed disk. FMM ID is a companion program which determines the mistuning in a particular rotor. Together, these methods provide a way to acquire data on the mistuning in a population of bladed disks, and then simulate the forced response of the fleet. This process is tested experimentally, and the simulated results are compared with laboratory measurements of a fleet of test rotors. The method is shown to work quite well. It is found that accuracy of the results depends on two factors: the quality of the statistical model used to characterize mistuning, and how sensitive the system is to errors in the statistical modeling.
True geometry tomography for velocity model building with applications to WATS seismic data (2008)

Tomography has been widely employed for velocity model building. The typical work flow starts with the migration of an initial velocity model. This is followed by picking residual moveouts and then updating the velocity through tomography. The migration process provides common image gathers and a stack. At the tomography stage, a ray tracer is used to trace specular rays from the image points to the surface to set up the system of linear equations for the tomographic inversion by linking valid ray pairs to their corresponding residuals. For narrow azimuth (NAZ) surveys, searching for valid ray pairs is usually limited to a narrow azimuth band. Since neither the gathers nor the stack contain acquisition geometry information, the selected specular ray pairs may not reflect the true ray paths, resulting in inaccurate rays being used in the inversion process. In addition to the problem of “which rays to choose”, we also have the problem of “how many rays to choose”. These problems are even more difficult to handle with acquisition configurations other than NAZ, such as the wide azimuth towed‐streamer (WATS) surveys, multi‐azimuth (MAZ) surveys, and ocean bottom cable (OBC) surveys. To overcome these problems, we propose a tomography method that incorporates the acquisition geometry information and uses vector offsets to account for both offsets and azimuths. To address the ill‐posed nature of the system of equations, we developed an anisotropic Laplacian regularization operator that allows different smoothing along different directions. We validate the method with tests on both synthetic and field data with a WATS geometry.
A New Stand-Alone Capillary Viscometer Used as a Continuous Size Exclusion Chromatographic Detector (1987)

This paper describes a new design of a forced-flow--through-type capillary viscometer used for batch sample viscosity measurements as well as continuous viscosity detection for size exclusion chromatography (SEC). In one version of our viscometer design, an analytical capillary is connected in series with a reference capillary in the flow stream and the pressure drop across the capillaries is measured by pressure transducers. A differential log-amplifier is used to convert the two transducer signals into an output signal that is directly proportional to the natural logarithm of the relative viscosity of the sample fluid. The output signal is highly insensitive to flow rate fluctuations and thus gives a very sensitive and accurate means to measure viscosity. The sample fluid could be any neat liquid or a sample of polymer solution. Under favorable conditions, a single viscosity determination on a polymer solution at high dilution can provide a direct measure of the polymer intrinsic viscosity, without the need of polymer concentration extrapolation. With this viscometer used as a continuous viscosity detector for SEC, it is possible to achieve SEC molecluar weight calibration by way of the universal SEC calibration methodology without the need of molecular weight standards for the unknown polymers.
Syntheses of 6,8‐disubstituted‐9‐β‐D‐ribofuranosylpurine 3′,5′‐cyclic phosphates (1975)

Abstract A series of 6,8‐disubstituted‐9‐β‐D‐ribofuranosylpurine 3′,5′‐cyclic phosphates were prepared employing preformed 9‐β‐D‐ribofuranosylpurine 3′,5′‐cyclic phosphate precursors. Three synthetic approaches were utilized to accomplish the syntheses. The first approach involved a study of the order of nucleophilic substitution, 6 vs 8, of the intermediate 6,8‐dichloro‐9‐β‐D‐ribofuranosyipurine 3′,5′‐cyclic phosphates ( 2 ) with various nucleophilic agents to yield 8‐amino‐6‐chloro‐, 8‐chloro‐6‐(diethylamino)‐, 6‐chloro‐8‐(diethylamino)‐, 6,8‐ bis ‐(diethylamino)‐ and 8‐(benzylthio)‐6‐chloro‐9‐β‐D‐ribofuranosylpurine 3′,5′‐cyclic phosphate (4, 9, 10, 11, 13) respectively and 6‐chloro‐9‐β‐D‐ribofuranosylpurin‐8‐one 3′,5′‐cyclic phosphate ( 5 ) and 8‐amino‐9‐β‐D‐ribofuranosylpurine‐6‐thione 3′,5′‐cyclic phosphate ( 6 ). The order of substitution was compared to similar substitutions on 6,8‐dichloropurines and 6,8‐dichloropurine nucleosides. The second scheme utilized nucleophilic substitution of 6‐chloro‐8‐substituted‐9‐β‐D‐ribofuranosylpurine 3′,5′‐cyclic, phosphates obtained from the corresponding 8‐subslituted inosine 3′,5′‐cyclic phosphates by phosphoryl chloride, 6,8‐ bis ‐(benzylthio)‐, 6‐(diethylamino)‐8‐(benzylthio),8‐( p ‐chlorophenylthio(‐6‐(diethylamino)‐ and 6,8‐ bis ‐(methyl‐thio)‐9‐β‐D‐ribofuranosylpurine 3′,5′‐cyclic phosphates ( 14, 12, 20 , and 21 ) respectively, were prepared in this manner. The final scheme involved N 1 ‐alkylation of an 8‐substituted adenosine 3′,5′‐cyclic phosphate followed by a Dimroth rearrangement to give 6‐(benzylamino)‐8‐(methylthio)‐ and 6‐(benzylamino)‐8‐bromo‐9‐β‐D‐ribofuranosylpurine 3′,5′‐cyclic phosphate ( 24 and 25 ).

Optical logic (1974)

Summary form only given. We report the theory and experimental demonstration of a laser device which performs the functions of binary arithmetic optically. Completely optical processing of logic functions could constitute a significant breakthrough in speed over conventional electronic processing. In our approach, input light pulses are assigned a binary code (0 or 1) according to their polarization along one of two mutually orthogonal directions. The response of the system to inputs of pairs of pulses consists of a pulse polarized along one of these initial orthogonal directions. The output pulse polarization can be made to correspond to those of the truth table for any of the logic operations of Boolean algebra. We report here achievement of the optical AND gate. The device is based on an optically excited dye laser whose cavity is birefringent. The birefringence reduces the degeneracy of the fundamental 479 mode to two orthogonal linear polarizations coincident with the birefringent axes. The input polarization controls the bistable polarization of the laser output by virtue of the photoselectively induced fluorescence dichroism of the dye medium. Relative adjustment of the respective thresholds for the two output polarizations provides the appropriate functional dependence for these logic operations. The experiment employed a Rh 6G jet stream dye laser pumped by a pulsed xenon ion laser. A novel two-beam polarizing interferometer generated the polarized input pulses. Further theoretical and experimental details will be presented, as well as an assessment of the future role of such devices.
Self organization of wireless sensor networks using ultra-wideband radios (2005)

Ultra-wideband (UWB) technology has proven to be useful in short range, high data rate, robust, and low power communications. These features can make UWB systems ideal candidates for reliable data communications between nodes of a wireless sensor network (WSN). However, the low powered UWB pulses can be significantly degraded by channel noise, inter-node interference, and intentional jamming. In This work we present a novel interference suppression technique for UWB based WSN that promises self-organization in terms of power conservation, scalability, and channel estimation for the entire distributed network.
Control of a variable speed, fault-tolerant permanent magnet generator (2002)

The control of power from a variable speed permanent magnet generator on the low pressure shaft of a gas turbine aero-engine is discussed. The application requires a fault tolerant generator (a high impedance design) to limit the fault current to the full load current at all speeds. The maximum power generation is constant over the whole speed range of the generator. The proposed system seeks to minimise the current rating of the converter and generator. The converter voltage is set at the minimum speed and then held constant as the speed increases. At higher speeds, reactive power is circulated between the generator and the converter to hold down the converter output voltage. This allows the design of the generator to be changed to increase the EMF, decreasing the current rating. At zero power demand, current still flows between the generator and the converter, except at the very lowest speeds. Under fault conditions the generator terminals must be short-circuited to limit the terminal voltage.
