<title>Application of wavelet and Wigner analysis to gas turbine vibration signal processing</title> (1998)

The analysis of gas turbine vibration is enhanced by the use of wavelet characterization and Wigner-Ville distribution processing to represent vibration features. The output of vibration sensors is digitized and the signal is processed by these means to identify signals associated with damage and progressive turbine wear. Wavelet processing provides fast transient detection useful in minimizing subsequent damage to turbine components through quick reaction. During turbine operation, short duration features appear, such as rotating stall conditions, that are well suited for detection with wavelet techniques. The Wigner-Ville distribution provides very accurate determination of vibration amplitudes in the nonstationary environment encountered in the use of gas turbines for vehicular propulsion. The Wigner-Ville distribution is described, and techniques for obtaining highly accurate amplitude information in the presence of noise and nonstationarity are presented. The wavelet transform is capable of making trade- offs between time and frequency resolutions, a property that makes it appropriate for the analysis for the analysis of nonstationary signals. Its ability to 'zoom in' on short lived high frequency phenomena is particularly attractive for the analysis of transients. Features of interest can be characterized form the evolution of the transform coefficients across distinct scales. Different types of wavelet transforms for an efficient time-frequency processing of the vibration signals are investigated. The resulting wavelet and Wigner features are used as inputs to a neural net which combine them with system health parameters. The result is a viable turbine monitor system, which can respond to long and short term events in a reliable and responsive manner.
Dyn Tail - Dynamically Tailored Deployment Engines for Cloud Applications (2015)

Shortening software release cycles increasingly becomes a critical competitive advantage, not exclusively for software vendors in the field of Web applications, mobile apps, and the Internet of Things. Today's users, customers, and other stakeholders expect quick responses to occurring issues and feature requests. DevOps and Cloud computing are two key paradigms to enable rapid, continuous deployment and delivery of applications utilizing automated software delivery pipelines. However, it is a highly complex and sophisticated challenge to implement such pipelines by installing, configuring, and integrating corresponding general-purpose deployment automation tooling. Therefore, we present a method in conjunction with a framework and implementation to dynamically generate tailored deployment engines for specific application stacks to deploy corresponding applications. Generated deployment engines are packaged in a portable manner to run them on various platforms and infrastructures. The core of our work is based on generating APIs for arbitrary deployment executables such as scripts and plans that perform different tasks in the automated deployment process. As a result, deployment tasks can be triggered through generated API endpoints, abstracting from lower-level, technical details of different deployment automation tooling.
Sequential Monte Carlo Methods to Train Neural Network Models (2000)

We discuss a novel strategy for training neural networks using sequential Monte Carlo algorithms and propose a new hybrid gradient descent sampling importance resampling algorithm (HySIR). In terms of computational time and accuracy, the hybrid SIR is a clear improvement over conventional sequential Monte Carlo techniques. The new algorithm may be viewed as a global optimization strategy that allows us to learn the probability distributions of the network weights and outputs in a sequential framework. It is well suited to applications involving on-line, nonlinear, and nongaussian signal processing. We show how the new algorithm outperforms extended Kalman filter training on several problems. In particular, we address the problem of pricing option contracts, traded in financial markets. In this context, we are able to estimate the one-step-ahead probability density functions of the options prices.
Novel surface modifying macromolecules (SMMs) blended polysulfone gas separation membranes by phase inversion technique (2011)

Abstract In this article an attempt was made to fabricate defect‐free asymmetric polysulfone (PSf) membranes for the separation of oxygen and nitrogen. The approach is based on the enhanced delayed demixing by blending surface modifying macromolecules (SMMs) in the casting solution and by immersing the cast film in isopropanol for a certain period before it is immersed in water. Different SMMs, including hydrophobic and charged SMMs, were synthesized, characterized, and blended to the host PSf. It was found that the charged SMM could indeed contribute to the removal of defective pores from the skin layer and enhancement of oxygen/nitrogen selectivity. The experimental results were further interpreted based on the shift of the phase boundary line on the polymer/solvent/nonsolvent triangular diagram, which occurred when SMMs were blended to PSf, due to the change in the polymer/nonsolvent interaction. © 2011 Wiley Periodicals, Inc.

Solid-Phase Extraction of Drugs from Biological Tissues—A Review (1992)

Solid-phase extraction procedures are being used increasingly in all types of drug testing laboratories, including those which carry out forensic toxicology. The advantages of such procedures include decreased operator time, reduced solvent volumes, and increased extraction efficiency. The application of existing techniques, however, has not yet been applied to tissues that are widely available postmortem. Tissue analysis can make the task of interpretation of drug levels much easier, particularly where unstable drugs are involved (e.g., cocaine). This review article explores the possibilities of applying existing extraction procedures to human tissue samples. We also consider the reasons why forensic laboratories have been slow to investigate such possibilities. We hope to stimulate interest in alternative tissue extraction procedures by reviewing reported procedures that apply to both human and animal tissue.
THE DEVELOPMENT OF TACHYPHYLAXIS TO ELECTRICAL STIMULATION IN GUINEA‐PIG ILEAL LONGITUDINAL MUSCLES AND THE POSSIBLE PARTICIPATION OF ADENOSINE AND ADENINE NUCLEOTIDES (1978)

Electrically (30 Hz) induced contractions of guinea‐pig isolated ileal longitudinal muscles were reduced by tetrodotoxin (1 μ m ), atropine (1 μ m ), adenosine (30 μ m ) and morphine (10 μ m ). When stimulated with 10 or 30 Hz for 10 s at 1 min intervals, a progressive decline of amplitude of the contraction was seen (development of tachyphylaxis). At this time, the contractile response to 1,1‐dimethyl‐4‐phenylpiperazinium iodide (DMPP) (10 μ m ) was also greatly reduced. The smaller responses to electrical stimulation and DMPP during tachyphylaxis were restored to their initial amplitude by the addition of theophylline (10 μ m ). The appearance of tachyphylaxis was prevented by pretreatment with theophylline (1 to 10 μ m ) and was greatly accelerated by pretreat‐ment with dipyridamole (0.1, 1 μ m ). In [ 14 C]‐choline or [ 3 H]‐adenosine preloaded muscle strips, electrical stimulation (30 Hz) increased the 14 C‐ or 3 H‐output, the effect being sensitive to tetrodotoxin blockade. The tachyphylaxis to electrical stimulation was accompanied by a considerable and sustained increase in 3 H‐output, an effect that was accelerated by dipyridamole (1 μ m ). The 14 C‐output initially increased but fell off gradually with the development of tachyphylaxis at which time theophylline (30 1) reversed the fall. There was a marked increase in the proportion of released [ 3 H]‐adenosine to its derivatives during the development of tachyphylaxis. Approximately 60% of the released total radioactivity after tachyphylaxis was found to be [ 3 H]‐adenosine. These results suggest that the development of tachyphylaxis may be closely associated with the release of endogenous adenosine derivatives (mostly adenosine) which have presynaptic inhibitory actions on the cholinergic elements in guinea‐pig ileum.
Influence of Reformed Gas Composition on HCCI Combustion of Onboard Methanol-Reformed Gases (2004)

<div class="htmlview paragraph">Adjusting the proportion of two fuels with different ignition properties is an effective technique for controlling ignition timing in homogeneous charge compression ignition (HCCI) combustion. One of the authors has proposed an HCCI combustion engine system fueled with dimethyl ether (DME) with a high cetane number and methanol reformed gas (MRG) with a high anti-knock property in the previous research. Both DME and MRG are to be produced from methanol by onboard reformers utilizing the exhaust heat from the engine in the system. The research has shown that adjusting the proportion of DME and MRG effectively controlled the ignition timing and load in HCCI combustion of the two fuels. High overall thermal efficiency has been shown over a wide operable range.</div> <div class="htmlview paragraph">While the MRG used in the research was the thermally decomposed methanol, which consists of hydrogen and carbon monoxide, methanol can be reformed into various compositions of hydrogen, carbon monoxide and carbon dioxide. The present paper aims to find the optimum MRG composition for the HCCI combustion engine system in terms of the ignition control and the overall thermal efficiency. The influence of MRG composition on the characteristics of ignition, combustion, engines efficiency and waste heat recovery is experimentally analyzed.</div> <div class="htmlview paragraph">The results show that an MRG model gas having a larger hydrogen amount has a higher effect of ignition control but a lower effect of waste heat recovery. The highest overall thermal efficiency is expected by using MRG by the thermal decomposition, while MRG by the steam reforming with the highest hydrogen fraction brings the highest output because of the strong ignition control.</div>
Skeleton based gesture to control manipulator (2015)

The key aspect to control the motion of manipulator intuitively is ability to map both joints on human and machine. This research proposes a method to interact with arm robot by using gesture based on skeleton image of user that is read from Kinect sensor. Velocity of each joint is defined by measuring angle rotation of every bone with respect to previous linked bone. Experiments has been carried out to manipulate SCORBOT-ER 9Pro with ability to handle 4 of 5 axises.
Advanced Signal Processing Techniques for Multi-Damage Detection With an Improved Embedded Ultrasonic Structural Radar Algorithm and Piezoelectric Wafer Active Sensors (2004)

The embedded ultrasonic structural radar (EUSR) algorithm was developed by using piezoelectric wafer active sensor (PWAS) array to detect defects within a large area of a thin-plate specimen. EUSR was verified to be effective for detecting a single crack either at a broadside or at an offside position. However, the damage location was not very precise. This algorithm is improved by using advanced signal processing techniques. The improvement includes: 1) EUSR is able to provide better image of the specimen under monitoring; 2) it is able to detect multiple defects such as several cracks; 3) it is also able to identify different damage types. This paper starts with an introduction of embedded ultrasonic structural radar algorithm. Then the application of using Hilbert transform for extracting the envelopes of the wave packages is discussed. This can eliminate or reduce the effect of side robes so that EUSR produces better images. The improvement of EUSR detectability is concluded through the comparison to the previous results, followed by the experiments to verify the multi-damage detection of EUSR. Finally, we present the results of how EUSR can distinguish different types of damage. This system is implemented by developing a graphical user-friendly interface program in LabView. We conclude with a description of our vision for an even more powerful EUSR for structural health monitoring and embedded nondestructive evaluation.

Rising from a Chair (1985)

We studied the effect of age on the act of rising from a standard armchair in a younger (means = 24 years) and an older (means = 75 years) group of healthy adult women. Rising from a standard armchair and an armchair specially designed for comfort in sitting of the elderly was studied in the older group to determine the influence of the special chair. We used electrogoniometry, EMG, and videotape analysis to record the activity for both groups. The older group placed their feet farther back and showed greater vastus lateralis muscle activity than did the younger group to rise from the standard chair. These results suggest that rising from the standard chair was more difficult for the older than for the younger group. In the special chair, the older subjects showed even more vastus lateralis muscle activity, greater knee flexion, and greater trunk forward lean. Rising from the special chair, therefore, appeared to be more difficult than rising from a standard chair; this finding suggests that both comfort and function must be considered in chair selection for certain groups.
Data flow languages (1979)

There are several computer system architectures which have the goal of exploiting parallelism-multiprocessors, vector machines and array processors. For each of these architectures there have been attempts to design compilers to optimize programs written in conventional languages (e.g. "vectorizing" compilers for the FORTRAN language). There have also been new language designs to facilitate using these systems, such as Concurrent PASCAL for multiprocessors,6 and languages that utilize the features of such systems directly, such as GLYPNIR for the Illiac IV array processor19 and various "vectorizing" dialects of FORTRAN. These languages almost always make the multiprocessor, vector, or array properties of the computer visible to the programmer-that is, they are actually vehicles whereby the programmer helps the compiler uncover parallelism. Many of these languages or dialects are "unnatural" in that they closely reflect the behavior of the system for which they were designed, rather than reflecting the way programmers think about problem solutions.
Radix 4 SRT Division with Quotient Prediction and Operand Scaling (2007)

SRT division is an efficient method for implementing high radix division circuits. However, as the radix increases the size of a quotient digit selection table increases exponentially. To overcome the limitations of quotient prediction, a method in which a quotient digit is speculated has been proposed. The speculated quotient digit is utilised to update the possible partial remainders while the speculated quotient is corrected. In this paper, instead of using a huge quotient selection table an estimation and correction scheme is used for prediction of quotient digit. The prediction is done in parallel with the calculation of the partial remainder for the quotient predicted earlier thus improving the latency. In addition, since this method tends to consume less area as the radix increases compared to previous methods, it has the ability to improve higher radix implementations for SRT division
Two-Dimensional Magnesium Phosphate Nanosheets Form Highly Thixotropic Gels That Up-Regulate Bone Formation (2016)

Hydrogels composed of two-dimensional (2D) nanomaterials have become an important alternative to replace traditional inorganic scaffolds for tissue engineering. Here, we describe a novel nanocrystalline material with 2D morphology that was synthesized by tuning the crystallization of the sodium-magnesium-phosphate system. We discovered that the sodium ion can regulate the precipitation of magnesium phosphate by interacting with the crystal's surface causing a preferential crystal growth that results in 2D morphology. The 2D nanomaterial gave rise to a physical hydrogel that presented extreme thixotropy, injectability, biocompatibility, bioresorption, and long-term stability. The nanocrystalline material was characterized in vitro and in vivo and we discovered that it presented unique biological properties. Magnesium phosphate nanosheets accelerated bone healing and osseointegration by enhancing collagen formation, osteoblasts differentiation, and osteoclasts proliferation through up-regulation of COL1A1, RunX2, ALP, OCN, and OPN. In summary, the 2D magnesium phosphate nanosheets could bring a paradigm shift in the field of minimally invasive orthopedic and craniofacial interventions because it is the only material available that can be injected through high gauge needles into bone defects in order to accelerate bone healing and osseointegration.
Buspirone in the long-term treatment of generalized anxiety disorder. (1987)

A 12-month, multicenter, open-label study was conducted to evaluate the long-term safety and efficacy of the new nonbenzodiazepine anxiolytic buspirone. The study population consisted of 700 patients with DSM-III generalized anxiety disorder who ranged in age from 16 to 84 years. Ninety-two percent had symptoms of anxiety that had persisted for 3 months or longer. According to the Hamilton Rating Scale for Anxiety, the Physician Global Opinion of Improvement, and the Patient Opinion of Improvement, the use of buspirone resulted in a significant reduction in anxiety. The degree of this improvement correlated with the duration of drug use. After the third month of therapy, there was an extremely low incidence of patient discontinuation due to side effects or insufficient improvement. Adverse effects were typical of those observed in other double-blind, placebo-controlled studies that compared buspirone with benzodiazepines. Overall, buspirone was well tolerated for maintenance therapy.
Loss Measurements of Surface Wave Transmission Lines (1954)

Loss measurements were made on ten dielectric coated wires used as surface wave transmission lines at a frequency of 9365 mc/sec. The purpose of these measurements was (1) to develop a satisfactory method for making the loss measurements, and (2) to compare the measured loss with the calculated or predicted value obtained from theoretical analysis made by Goubau. A resonance method, in which the Q of a resonator formed by short circuiting both ends of a length of line is determined, was found to be most desirable. The loss in the resonator end plates was taken into account in determining the wire loss. A description of the apparatus required and the experimental procedures used is given. A brief discussion of alternative methods for making the loss measurements, some of which have been tried, is also given. The losses of the wires measured ranged from about 3.0 db/100 feet for thin dielectric coatings to about 11.5 db/100 feet for thick dielectric coatings. The agreement between measured and calculated losses of wires for which the constants of the dielectric coating are known is considered good.

Cryotherapy: Review of physiological effects and clinical application (1985)

Cryotherapy, the therapeutic use of cold in the management of injuries and painful conditions, can be a valuable technique for the medical practitioner. The physiologic effects of cold are vasoconstriction, which helps to decrease swelling and inflammation; decreased tissue hypoxia; decreased pain; and decreased muscle spasm. Integrating cold in both the acute and rehabilitation stage can promote quick and effective results. Combining cold with exercise (cryokinetics) has significant clinical implications for the treatment of many musculoskeletal problems, athletic injuries, and inflammatory conditions such as tendonitis, bursitis, and arthritis. Application of ice provides a safe, convenient, and inexpensive method of treatment for the patient, especially in the home setting.
