Modeling of Tilting‐Pad Journal Bearings with Transfer Functions (1999)

Tilting‐pad journal bearings are widely used to promote stability in modern rotating machinery. However, the dynamics associated with pad motion alters this stabilizing capacity depending on the operating speed of the machine and the bearing geometric parameters, particularly the bearing preload. In modeling the dynamics of the entire rotor‐bearing system, the rotor is augmented with a model of the bearings. This model may explicitly include the pad degrees of freedom or may implicitly include them by using dynamic matrix reduction methods. The dynamic reduction models may be represented as a set of polynomials in the eigenvalues of the system used to determine stability. All tilting‐pad bearings can then be represented by a fixed size matrix with polynomial elements interacting with the rotor. This paper presents a procedure to calculate the coefficients of polynomials for implicit bearing models. The order of the polynomials changes to reflect the number of pads in the bearings. This results in a very compact and computationally efficient method for fully including the dynamics of tilting‐pad bearings or other multiple degrees of freedom components that interact with rotors. The fixed size of the dynamic reduction matrices permits the method to be easily incorporated into rotor dynamic stability codes. A recursive algorithm is developed and presented for calculating the coefficients of the polynomials. The method is applied to stability calculations for a model of a typical industrial compressor.
Enhancing Image Denoising Performance of Bidimensional Empirical Mode Decomposition by Improving the Edge Effect (2015)

Bidimensional empirical mode decomposition (BEMD) algorithm, with high adaptive ability, provides a suitable tool for the noisy image processing, and, however, the edge effect involved in its operation gives rise to a problem—how to obtain reliable decomposition results to effectively remove noises from the image. Accordingly, we propose an approach to deal with the edge effect caused by BEMD in the decomposition of an image signal and then to enhance its denoising performance. This approach includes two steps, in which the first one is an extrapolation operation through the regression model constructed by the support vector machine (SVM) method with high generalization ability, based on the information of the original signal, and the second is an expansion by the closed-end mirror expansion technique with respect to the extrema nearest to and beyond the edge of the data resulting from the first operation. Applications to remove the Gaussian white noise, salt and pepper noise, and random noise from the noisy images show that the edge effect of the BEMD can be improved effectively by the proposed approach to meet requirement of the reliable decomposition results. They also illustrate a good denoising effect of the BEMD by improving the edge effect on the basis of the proposed approach. Additionally, the denoised image preserves information details sufficiently and also enlarges the peak signal-to-noise ratio.

Incremental outlier detection in data streams using local correlation integral (2009)

In this paper, an incremental outlier detection technique capable of dealing with a large amount of data is presented and evaluated in the context of intrusion detection. The proposed method is based on the LOcal Correlation Integral (LOCI for short). The detection technique consists of two parts. The first part named insertion receives the sequence of input point and updates Multi-granularity DEviation Factor (MDEF) of the point at intervals. The second part named deletion deletes one or a batch of points. This technique is able to process streaming data in a single scan. Moreover, the number of updates in the incremental LOCI algorithm per insertion/deletion of a single data record does not depend on the total number of data records. Experimental results with real life data sets show that the technique is capable of dealing with data streams, successfully detecting outlier.
Unsupervised feature selection for linked social media data (2012)

The prevalent use of social media produces mountains of unlabeled, high-dimensional data. Feature selection has been shown effective in dealing with high-dimensional data for efficient data mining. Feature selection for unlabeled data remains a challenging task due to the absence of label information by which the feature relevance can be assessed. The unique characteristics of social media data further complicate the already challenging problem of unsupervised feature selection, (e.g., part of social media data is linked, which makes invalid the independent and identically distributed assumption), bringing about new challenges to traditional unsupervised feature selection algorithms. In this paper, we study the differences between social media data and traditional attribute-value data, investigate if the relations revealed in linked data can be used to help select relevant features, and propose a novel unsupervised feature selection framework, LUFS, for linked social media data. We perform experiments with real-world social media datasets to evaluate the effectiveness of the proposed framework and probe the working of its key components.
Student Writing in Transition: Crossing the Threshold? (2011)

The following set of three papers, ‘University Literacies: French Students at a Disciplinary “Threshold”?’ by Isabelle Delcambre and Christiane Donahue, ‘Modeling Multivocality in a U.S.-Mexican Collaboration in Writing across the Curriculum’, by Mya Poe and Jennifer Craig, and ‘Perceptions and Anticipation of Academic Literacy: “Finding Your Own Voice”’, by Claire Woods and Paul Skrebels, represents some of the ongoing practice-oriented research of the ‘Antwerp Group’, so called because the members came together as teacher-researchers with shared interests in student writing in Antwerp in 2006.
Illumination-invariant texture classification using simple training images (2005)

The appearance of a surface texture is highly dependent on illumination. This is why current surface texture classification methods require multiple training images captured under a variety of illumination conditions for each class. We show that a single training image per class can be sufficient if the surfaces are of uniform albedo and smooth and shallow relief, and the illumination is sufficiently far from the texture macro-normal. The performance of our approach is demonstrated on classification of 20 textures in the PhoTex database. For test images which are most different from the training images (different instances of the same texture observed, non-equal illumination slants), the success rate achieved is in the range of 60‐80%. When the test images differ from the training ones only in illumination tilt, the success rate achieved is well above 95%.
A multipath transport system based on application level relay (2015)

Multipath transport is an important way to improve the transmission performance of Internet applications. This demo presents a multipath transport system based on application level relay (MPTS-AR), which defines three kinds of logical entity of user agent, controller and relay server. Controller and relay server collaboratively provide relay services, and user agent integrates the multipath transmission control mechanism and protocol stack. It also defines a relay service control protocol named OpenPath in control plane and a suite of multipath transport protocols (MPTPs) in data plane. The example of SIP-based real-time audio media session further illustrates the practicability of MPTS-AR.
Characterization of an Atmospheric Pressure Radio-Frequency Capacitive Plasma Jet (2007)

There is a steadily growing interest in non-equilibrium atmospheric pressure plasmas for materials processing. One of the plasma sources developed for this purpose is the atmospheric pressure plasma jet (APPJ), which is characterized by an alpha-mode of a radio-frequency (RF) discharge between two bare metallic electrodes. We developed an APPJ with planar electrodes and operated the APPJ with helium/argon process gas mixtures ranging from pure helium to pure argon and characterized the discharges. The alpha-discharge can be sustained in all process gas mixtures investigated. The sustainable electron density in the alpha-mode increases steadily with increasing argon content.
A transistor-only current-mode Sigma Delta modulator (1992)

Current copier circuits are used in the IC realization of a transistor-only second-order Sigma Delta modulator. By using current copiers, it is possible to implement the modulator without using linear capacitors, as is required for switched-capacitor approaches. Design considerations based on settling time and noise for a current copier circuit are presented, along with the description of the current output D/A and the current quantizer. The modulator has been fabricated in a 0.9- mu m digital CMOS process and achieves 13-b resolution and 12-b linearity over the voiceband frequency range.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
The Production of High-Purity Water in the Clinical Laboratory (2000)

As the sensitivity and variety of tests increase, the types and tolerable concentrations of impurities that may inhibit clinical tests become an increasing concern. Because water constitutes a high percentage of the buffers and reaction mixtures used in clinical assays, the use of high-purity water is critical for reliable, consistent, and cost-effective laboratory analysis. A wide range of contaminants exists in potable water supplies and must be removed with a water system containing the proper combination of specific purification technologies. Technologies such as activated carbon, reverse osmosis, ion exchange, and distillation have particular purification capabilities and must be selected based on their ability to consistently produce water with purity suitable for specific test methods. The National Committee for Clinical Laboratory Standards (NCCLS) provides guidelines for the production and use of purified water in the laboratory. The production of reagent water that meets the NCCLS guidelines requires proper measurement and monitoring of contaminant levels in both incoming source water and product reagent water. The introduction of new diagnostic tests requires the removal and monitoring of contaminants, such as nucleases and extraneous DNA, and creates new criteria for water purity and water system design. Current water purification technologies are reviewed, and a system designed to provide type I water is discussed.
A robust growing-pruning algorithm using fuzzy logic (2002)

We describe a fuzzy-logic controlled growing and pruning algorithm for improved fault-tolerance in a multilayer perceptron. This algorithm is intended for classification tasks. The importance of each weight connection, and hence of each hidden neuron, of the network is determined as a fuzzy-logic function of the increase in the mean-squared error and the decrease in the number of correct classifications upon the injection of faults. The hidden neurons may be either duplicated or pruned depending upon their relative importance in the classification task. We compare our network to a 4-augmented multilayer perceptron with 12 hidden neurons and find that they both have the same level of fault tolerance, however the former is smaller. We then use the immunization technique with our algorithm and find that the number of weight connections can be further significantly reduced.

STOREY ELEMENT FOR ANALYZING FRAME-SHEAR WALL STRUCTURES (2009)

A storey element, which can simulate one storey of the frame-shear wall structure, is established by simply summing the rigidity matrixes of the frame and wall. The internal forces and displacements of the frame-shear wall structures for various rigidity characteristics with the constant stiffness under various kinds of loads are calculated by the beam element method, storey element method and analytical formulas. The internal forces and displacements with the variable stiffness along the height under uniformly distributed load are calculated by the beam element method and storey element method. In comparison with the beam element method, the storey element method can remarkably reduce the volume of input, output data and calculation, the error is less than 8.3%.

Overview of Certification Systems: X.509, CA, PGP and SKIP (1999)

Cryptography and certification are considered necessary Internet features and must be used together, for example in ecommerce. This work deals with certification issues and reviews the three most common methods in use today, which are based on X.509 Certificates and Certification Authorities (CAs), PGP and, SKIP. These methods are respectively classified as directory, referral and collaborative based. For two parties in a dialogue the three methods are further classified as extrinsic, because they depend on references which are outside the scope of the dialogue. A series of conceptual, legal and implementation flaws are catalogued for each case, emphasizing X.509 and CAs, which helps to provide users with safety guidelines to be used when resolving certification issues. Governmental initiatives introducing Internet regulations on certification, such as by TTP, are also discussed with their pros and cons regarding security and privacy. Throughout, the paper stresses the basic paradox of...
Cooperative spectrum sensing technique based on sub space analysis for cognitive radio networks (2009)

Abstract—Recently, a new blind spectrum sensing technique based on signal space dimension estimation was developed for sensing the spectrum holes in the primary user’s bands. The mean idea of this technique is that the number of significant eigenvalues of the covariance matrix of the received signal is directly related to the presence/absence of data in the signal. In this paper 1, we study the collaborative sensing as a means to improve the performance of the proposed spectrum sensing technique and show their effect on cooperative cognitive radio network. Specifically, we will present the performance evaluation and advantages of this method and propose an optimization method that compute only the first dominates eigenvalues in order to reduce the complexity of the proposed cooperative spectrum sensing algorithm. Simulations results and performances evaluation presented in this paper are based on experimental measurements captured by Eurecom RF Agile Platform. Keywords—Cognitive radio, cooperative spectrum sensing, sub space analysis, eigenvalues. I.
The haemochromatosis candidate gene HFE (HLA-H) of man and mouse is located in syntenic regions within the histone gene cluster (1998)

The HFE (HLA-H) gene is a strong candidate gene for hereditary haemochromatosis and was localized on the short arm of chromosome 6 to 6p21.3-p22. In addition, the sequence of the homologous mouse and rat cDNA and a partial sequence from the mouse gene have been reported recently. In this report, we describe the location of the human and the mouse HFE (HLA-H) gene within the histone gene clusters on the human chromosome 6 and the mouse chromosome 13. Both the human and the murine gene were located on syntenic regions within the histone gene clusters in the vicinity of the histone H1t gene. The genomic sequence of the human HFE (HLA-H) gene and the 3' portion of the homologous mouse gene were determined. Comparison of the genomic sequences from man and mouse and the cDNA sequence from rat shows significant similarities, also beyond the transcribed region of the mouse gene.
Experimental Replacement of the Superior Vena Cava (1968)

MANY reports are available describing the experimental replacement of the superior vena cava by various synthetic grafts.<sup>1-4</sup>Success rates vary, but as yet no really reliable material has been found. Thrombosis of grafts, both immediate and late, has been the main source of failure; and therefore, the frequency of this complication is the standard by which a new technique or material is judged. Autologous vein grafts have been the most successful superior caval grafts.<sup>5</sup>Thrombus-resistant grafts of Dacron treated with graphite-benzalkonium-heparin (GBH), according to the technique of Gott, have been used with some success.<sup>6</sup>Untreated Dacron grafts have been associated with high rates of thrombosis.<sup>7</sup>Inverted jejunal grafts have been reported to have a 100% success rate.<sup>8</sup> The experiments reported here constitute a comparative investigation of five different types of graft used for superior vena caval replacement. Long-term follow-up results are reported in all groups.
Organization of Glycosphingolipids in Bilayers and Plasma Membranes of Mammalian Cells (1985)

The evidence presented in this review strongly suggests that, when present as a minor component in liquid crystalline phospholipid bilayers, neutral glycosphingolipids are segregated into compositional domains of small size dispersed in the matrix phospholipid. In many instances the glycosphingolipid in the dispersed domains is in the gel state. Because these domains are in the gel state, the individual molecules escape only very slowly from the surface of the bilayer, much more slowly than do the phospholipid components. There is as yet no direct evidence that this slow escape rate is a property of neutral glycolipids in biological membrane bilayers. If it is, however, then these molecules are well suited for their putative role as cell surface markers, a role that involves them in many important biological functions. There is evidence to suggest that molecules of this type are also present in a dispersed microdomain structure on the external surface of at least some mammalian cell plasma membranes. These small domains of glycolipids with their sugar residues projecting outward from the cell surface are much like a large membrane glycoprotein when viewed from the ambient medium near the cell surface. Thus, whether the sugar residues be of glycoprotein or glycolipid origin, they are localized in groups or patches on the external surface of the cell. One important consequence of this patch structure may be in the obvious effect on the free energy of binding a ligand to a patch. Whether the ligand is mono- or polyvalent, the roughly 2 M concentration of sugar in the surface patch will cause the apparent ligand binding free energy to be substantially larger than it would be for a single isolated sugar residue on the surface. In contrast to the neutral glycosphingolipids (and sulfatides, perhaps) the available information suggests that gangliosides are not localized in small domains in model systems and most probably not in biological membranes. Capping of this type of glycosphingolipid does appear to occur under certain circumstances. However, it is almost certain that capping is not an intrinsic property of ganglioside phospholipid-bilayer systems. Although at 37 degrees C gangliosides rapidly transfer from micelles to phospholipid vesicles and to cell membranes, nothing is known about the rates at which this class of molecules leave a phospholipid bilayer. Their known biological functions on the cell surface appear to require that they leave very slowly, if at all, as do the neutral glycosphingolipids. The glycosphingolipids are, by virtue of their polysaccharide moeity, a unique class of lipids and cell surface components.(ABSTRACT TRUNCATED AT 400 WORDS)

Injuries in an Elderly Inner‐City Population (1990)

Even though injuries are a leading cause of morbidity and mortality among the elderly in the United States, no comprehensive population-based study of nonfatal and fatal injuries has been carried out in an elderly minority inner-city population. To study injuries in this population, we developed an active surveillance system as part of a large injury prevention program in a poor urban black community. We report 577 cases of nonfatal and fatal injuries in a community of 12,139 persons 65 years of age and older that resulted in emergency room treatment or death between March 1, 1987, and February 29, 1988. Nearly 5% of the elderly population was treated at an emergency room for, or died as a result of, an injury during the study period; the overall injury rate was 48 injuries per 1,000 persons. Injury rates for older women exceeded those for older men and increased with advancing age in both sexes. Fall injuries accounted for 312 (54%) of all injuries and 75% of all hospitalizations for injury. Motor vehicle incidents and violence were the second and third most common injuries, accounting for 13% and 7% of injuries, respectively. Given the predominance of falls relative to other injuries, prevention of falls should receive major emphasis in injury prevention efforts in inner-city minority populations.
