IN SITU RAILWAY TRACK FAULT DETECTION USING RAILCAR VIBRATION (2014)

This thesis investigates the development of an automated fault detection system developed for a novel lightweight railway material haulage system; in particular, the study aims to detect railway track faults at the incipient stage to determine the feasibility of maintenance decision support, ultimately with the function of preventing catastrophic failure. The proposed approach is an extension of the current state of the art in fault detection of unsteady machinery.\nThe most common railway track faults associated with train derailment were considered; namely, horizontal and transverse crack propagation, mechanical looseness, and railbed washout were the faults of interest. A series of field experiments were conducted to build a database of vibration, speed, and localization data in healthy and faulted states. These data were used to develop, investigate, and validate the effectiveness of various approaches for fault detection.\nA variety of feature sets and classification approaches were investigated to determine the best overall configuration for the fault detector. The feature sets were used to condense data segments and extract characteristics that were sensitive to damage, but insensitive to healthy variations due to unsteady operation. The pattern recognition classifiers were used to categorize new data members as belonging to the healthy class or faulted class.\nThe fault detection results from the proposed approach were promising. The feasibility of an automated online fault detection system for the lightweight material haulage system examined in this study was confirmed. The conclusions of this research outline the major potential for an\niv\neffective fault detection system and address future work for the practical implementation of this system.

Cigarette smoking and lung destruction. Accumulation of neutrophils in the lungs of cigarette smokers. (1983)

It has been hypothesized that lung destruction in persons with emphysema associated with cigarette smoking is mediated by elastase released by neutrophils that have migrated to the alveolar structures in response to cigarette smoke. To directly evaluate this hypothesis, cell suspensions, isolated from bronchoalveolar lavage fluid and from open lung biopsies of nonsmokers and cigarette smokers with normal lung parenchyma and from open lung biopsies of nonsmokers and cigarette smokers who have sarcoidosis were evaluated for the presence of neutrophils. A significantly increased number of neutrophils was present in the cell suspensions isolated from bronchoalveolar lavage fluid and from open lung biopsies of both normal and sarcoid cigarette smokers compared with that in the nonsmokers (p less than 0.01, each comparison). Evaluation of the alveolar macrophages present in lavage fluid suggested a mechanism by which neutrophils may be attracted to the lungs of cigarette smokers: alveolar macrophages of cigarette smokers release a chemotactic factor for neutrophils, whereas alveolar macrophages of nonsmokers do not. In addition, alveolar macrophages of nonsmokers, after exposure to cigarette smoke, in vitro, are stimulated to release this chemotactic factor. These studies demonstrate that an increased number of neutrophils are present in the lungs of cigarette smokers compared with that in nonsmokers and suggest that cigarette smoke may attract neutrophils to the lung by stimulating alveolar macrophages to release a potent chemotactic factor for neutrophils.
A Novel Type of AmpC β-Lactamase, ACC-1, Produced by a <i>Klebsiella pneumoniae</i> Strain Causing Nosocomial Pneumonia (1999)

A Klebsiella pneumoniae strain resistant to oxyimino cephalosporins was cultured from respiratory secretions of a patient suffering from nosocomial pneumonia in Kiel, Germany, in 1997. The isolate harbors a bla resistance gene located on a transmissible plasmid. An Escherichia coli transconjugant produces a beta-lactamase with an isoelectric point of 7.7 and a resistance phenotype characteristic of an AmpC (class 1) beta-lactamase except for low MICs of cephamycins. The bla gene was cloned and sequenced. It encodes a protein of 386 amino acids with the active site serine of the S-X-X-K motif at position 64, as is characteristic for class C beta-lactamases. Multiple alignment of the deduced amino acid sequence with 21 other AmpC beta-lactamases demonstrates only very distant homology, reaching at maximum 52.3% identity for the chromosomal AmpC beta-lactamase of Serratia marcescens SR50. The beta-lactamase of K. pneumoniae KUS represents a new type of AmpC-class enzyme, for which we propose the designation ACC-1 (Ambler class C-1).
자궁경부의 상피내암에 대하여 (1959)

자궁경부의 상피내암에 관해서는 그 병리와 진단 및 치료면에 있어서 아직도 일정한 정설을 보지 못하고 있는 현상이다. 상피내암에 대한 기재는 May & Charlotte에 의하면 80년전에 John Williams가 기재한 것이 시초라고 한다. 그러나 Held에 의하면 Schauenstein(1908)이 Oberflacher atypischer Belag라고 기재한 것이 시초라 하며, 그 익년 Pronair(1909)가 유사한 예를 발표하였다고 한다.Rubin(1910)은 Schottlander의 지도하에Obuerflachen-Karzinom이라고 해서 그 예를 발표하였다. 상피내암을 carcinoma in situ라고 한 것은 Broders(1932)이며 Galvin & TeLinde(1948)는 intraepithelial carcinoma라고 하였고 불란서에서는 epithelioma intra-epithelial이라고 칭하고 있다. 이미 약 10년전에 독일에서 Robert Meryer는 Henke-Lubarsch Handbuch내에 자궁의 histopatholgy를 취급한 부문에서 그에 관한 기재를 하였다. Robert Meyer는 본제의 병조를 약 30년동안 추구하였다하며 Schiller도 또한 장구한 관찰을 하였다고 한다. 그후 오랜 시일동안의 수많은 관찰결과가 보고되었다. 그들은 경암의 조기병조를 발견함에 있어서 무엇보다도 먼저 흔히 볼 수 있는 치유기마란(Erosion healing)과의 정확한 객관적 감별점을 기재하였는데 사실상 치유기마란과 조기경암병조와의 구별은 대개의 경우 그리 어려운 것은 아니나 역시 용치 않은 때도 부소하다. 그들은 carcinoma in situ라는 말을 사용하지 않고 암의 조기변화와 같이 보이는 모든 특성을 신중히 검토하였다. 그리고 그들은 현금에 있어서도 유용한 암에 대한 다음과 같은 특성을 강조하였다. 즉 「암」이라는 것을 그것을 방임하는 경우에는 환자를 결국 사망케 하고야 만다는 것을 역설하였다.
ANALYTICAL CALCULATION OF PARALLEL DOUBLE EXCITATION AND SPOKE-TYPE PERMANENT-MAGNET MOTORS; SIMPLIFIED VERSUS EXACT MODEL (2013)

This paper deals with the prediction of magnetic fleld distribution and electromagnetic performances of parallel double excitation and spoke-type permanent magnet (PM) motors using simplifled (SM) and exact (EM) analytical models. The simplifled analytical model corresponds to a simplifled geometry of the studied machines where the rotor and stator tooth-tips and the shape of polar pieces are not taken into account. A 2D analytical solution of magnetic fleld distribution is established. It involves solution of Laplace's and Poisson's equations in stator and rotor slots, airgap, buried permanent magnets into rotor slots and non magnetic region under magnets. A comparison between the results issued from the simplifled model with those from exact model (EM) (which represents a more realistic geometry with stator and rotor tooth-tips and the shape of polar pieces) is done to show the accuracy of the simplifled geometry on magnetic fleld distribution and electromagnetic performances (cogging torque, electromagnetic torque, ∞ux linkage, back-EMF, self and mutual inductances). The analytical results are verifled with those issued from flnite element method (FEM).
Catalytic Hydrolysis of Ammonia Borane <i>via</i> Cobalt Palladium Nanoparticles (2011)

Monodisperse 8 nm CoPd nanoparticles (NPs) with controlled compositions were synthesized by the reduction of cobalt acetylacetonate and palladium bromide in the presence of oleylamine and trioctylphosphine. These NPs were active catalysts for hydrogen generation from the hydrolysis of ammonia borane (AB), and their activities were composition dependent. Among the 8 nm CoPd catalysts tested for the hydrolysis of AB, the Co(35)Pd(65) NPs exhibited the highest catalytic activity and durability. Their hydrolysis completion time and activation energy were 5.5 min and 27.5 kJ mol(-1), respectively, which were comparable to the best Pt-based catalyst reported. The catalytic performance of the CoPd/C could be further enhanced by a preannealing treatment at 300 °C under air for 15 h with the hydrolysis completion time reduced to 3.5 min. This high catalytic performance of Co(35)Pd(65) NP catalyst makes it an exciting alternative in pursuit of practical implementation of AB as a hydrogen storage material for fuel cell applications.
Vital Bleaching: A New Light‐Activated Hydrogen Peroxide System (1992)

With ever increasing interest in cosmetic enhancement of dentition by dentists and patients alike, this article introduces a new light-activated bleaching system that adds up to total patient satisfaction and reduced chair time. The chairside application of hydrogen peroxide 30% was effective in lightening a moderate case of tetracycline staining. The uniqueness of this system allows the practitioner complete control within an office setting, and it provides the patient with an immediate result. The ease of application and strict supervision of a dentist has allowed this system to satisfy recent watchdogs of the Federal Drug Administration.
Prime factor decomposition of the discrete cosine transform and its hardware realization (2005)

The discrete cosine transform (DCT) is an useful tool in solving many digital signal processing problems. One of its more interesting applications is in the realization of a bandpass filter-bank that is necessary to perform conversion between time-division and frequency-division voice multiplexing systems. In this particular example the transform size is dictated by the sampling frequencies and the computationally-efficient power-of-2 algorithms may not applicable. To handle such situations, a new DCT algorithm based on a prime factor decomposition of the transform-length is presented in this paper. To begin with, the definition of the DCT is introduced with a brief discussion of the application mentioned. The existence of the prime factor decomposition technique is derived based on a similar decomposition for the discrete Fourier transform (DFT). The prime factor algorithm for the DCT (PFA-DCT) is then described step by step and followed by an example of a 12-point transform which delineates the method and brings out the essence of the algorithm. A hardware implementation of a 72-point DCT is outlined to illustrate the usefulness of this algorithm in practical systems.
EVOLUTION IN DER LENKUNGSTECHNOLOGIE. EIN BEITRAG ZUR STEIGERUNG DER AKTIVEN SICHERHEIT. TEILE 1 UND 2 (1991)

Zur technologischen Weiterentwicklung des Kraftfahrzeugs in den naechsten Jahrzehnten wird das Lenkungssystem in nicht unerheblichem Masse beitragen. Erste Ansaetze zur Schaffung einer Parameterlenkung, die im Hinblick auf ein gesteigertes Sicherheitsniveau erstrebenswert erscheint, bieten solche Systeme, die dem jeweiligen Fahrzustand angepasste Servounterstuetzung und Lenkuebersetzung anbieten. Das Konzept eines integral geregelten Fahrwerks mit aktiver Eingriffnahme geht jedoch darueber hinaus und verlangt nach zusaetzlicher Flexibilitaet des Lenkungssystems, die in optimierter Form wahrscheinlich durch unabhaenig geregelte Radstellglieder an allen vier Raedern erreichbar ist. Aufgrund der steigenden Komplexitaet der Lenkungssysteme gewinnen gleichzeitig Massnahmen zur Senkung von Bauteilgewicht und Energieverbrauch an Stellenwert. Denkbar ist hier die Verwendung neuartiger Materialien sowie anderer Energieformen fuer die Servounterstuetzung beziehungsweise fuer den Radstellwinkelvorgang.

Serum levels of soluble interleukin‐2 receptor, C‐reactive protein, neopterin, myoglobin and light chains of cardiac myosin fail to correlate with the occurrence of rejection in long‐term renal and heart transplant patients (1992)

Even in the late phase following heart and kidney transplantation (> 1 year post‐Tx) there are still acute interstitial rejections which are generally verified by invasive diagnosis (biopsy). We raised the question whether serum parameters pointing to immunologic activation (neopterin, C‐reactive protein [CRP], soluble interleukin‐2 receptor [sIL‐2R]), which have been described to be diagnostically relevant for an “early” rejection (during the first months post Tx), are also suitable for noninvasive diagnosis of “late” rejections of heart and kidney transplants. In addition, myoglobin and light chains of cardiac myosin (myosin L‐chains), being markers pointing to an ischemically injured myocardium, have been quantified in the serum of heart transplant recipients. 161 heart allograft recipients (13 with moderate to severe rejection, 34 with mild rejection) and 20 kidney allograft recipients (10 with acute rejection) were investigated in this study. In all cases, the diagnosis has been confirmed by the histology of transplant biopsy. More than 300 sera have been investigated. Although about one third of the patients had an increased sIL‐2R level and more than 80% of the heart transplant patients increased myoglobin and myosin L‐chain levels (10% even strongly increased), we were not able to detect a significant relation between the increase in serum parameters and the occurrence and degree of rejection in long‐term transplant patients. We therefore concluded that the serum parameters tested are not suitable for non‐invasive rejection diagnosis in the late phase after transplantation. Long‐term follow‐up studies will show whether increased myoglobin and myosin L‐chain levels in heart transplant recipients might be considered as an early diagnostic marker for coronary artery disease.
A Mathematical Model of Tumor Volume Changes during Radiotherapy (2013)

Validation study with patient data demonstrated feasibility and clinical usefulness of the new model in predicting tumor volume change in radiotherapy.
Risk of Hepatocellular Carcinoma Across a Biological Gradient of Serum Hepatitis B Virus DNA Level (2006)

Elevated serum HBV DNA level (> or =10,000 copies/mL) is a strong risk predictor of hepatocellular carcinoma independent of HBeAg, serum alanine aminotransferase level, and liver cirrhosis.
Attention as selection-for-action: a scheme for active perception (2003)

Proposes three principles for attentional control of actions in autonomous robots. (1) Attention-as-action suggests that attentional shifts and the selection of the focus of attention should be seen as actions rather than as a purely sensory process. (2) Selection-for-action suggests that actions should be implicitly controlled by the current focus of attention. (3) Deictic reference is a method of referring to an external object without explicitly representing all of its properties. The three principles are illustrated in two examples: first for a mobile robot, and second for a visually controlled manipulator. In the second example, we also report two learning experiments where a robot picks out the correct focus of attention for a task based on reinforcement learning.
Sodium Fluoride Susceptibilities of Suspected Periodontopathic Bacteria (1983)

Utilizing a blood-based medium, we determined the minimum inhibitory concentrations (MIC's) to sodium fluoride (NaF) of 45 bacterial strains representing 22 oral species. Bacterial susceptibility ranged from 128 micrograms/ml to 2048 micrograms/ml. Of those organisms tested, Actinobacillus actinomycetemcomitans, Capnocytophaga sputigena, Capnocytophaga gingivalis, Capnocytophaga ochracea, and Actinomyces viscosus were susceptible at lower levels of NaF.
Studies on Pasteurella multocida. VI. Nature of Systemic Immunity and Analysis of the Correlation between Levels of Immunity Induced by Various Fowl Cholera Vaccines and Protection against Challenge (1978)

The nature of the systemic immunity induced by various vaccines against fowl cholera disease in turkeys was investigated. Used as vaccines were three avirulent strains (CU, M2283, and P1580) of Pasteurella multocida administered in the drinking water and a bacterin administered parenterally. A passive hemagglutination test was developed to measure levels of systemic humoral immunity. Systemic cell-mediated immune response was assayed by an in vitro immunostimulation microculture system utilizing peripheral blood lymphocytes. The bacterin induced high levels of systemic humoral and cell-mediated immune responses which respectively persisted for 8 and 6 weeks. The CU strain of live vaccine induced average levels of systemic immunity (humoral and cell-mediated) which respectively persisted for 4 and 6 weeks. The M2283 strain of live vaccine also induced average levels of systemic immunity (less than induced by the CU strain) which respectively persisted for 4 and 6 weeks. The P1580 strain of live vaccine induced low levels of systemic immunity which persisted for only 2 weeks. Results from data generated from an analysis of correlation between levels of immunity and protection indicate that systemic immunity (humoral and cell-mediated) played a significant role.

Machinability study and optimization of tool life and surface roughness of ferrite: Bainite dual phase steel (2022)

Aim of this present research work is to obtain the machining parameters to optimize the tool life and surface roughness for ferrite-bainite dual phase steel. Machinability tests are carried out using orthogonal array of 27, the Taguchi method, in which the machining parameters are considered as control factors. The effect of speed, feed and depth of cut on tool life and surface roughness of dual phase structure steel is analysed using ANOVA. Regression analysis is used to obtain the equations for predicting the tool life and surface roughness. Experiment is conducted using uncoated carbide insert tool by varying the process parameters. Optimum tool life and surface is analysed using Response Surface Methodology. Hardness and microstructure revealed the dual phase condition in different intercritical zones. It is found that hardness improves as the intercritical temperature is increased from 750 to 770°C. Experimental results prove that dual phase structure has better machining characteristics at an intercritical temperature of 750°C.
Post-transcriptional modification in archaeal tRNAs: identities and phylogenetic relations of nucleotides from mesophilic and hyperthermophilic Methanococcales (2001)

Post-transcriptional modifications in archaeal RNA are known to be phylogenetically distinct but relatively little is known of tRNA from the Methanococci, a lineage of methanogenic marine euryarchaea that grow over an unusually broad temperature range. Transfer RNAs from Methanococcus vannielii, Methanococcus maripaludis, the thermophile Methanococcus thermolithotrophicus, and hyperthermophiles Methanococcus jannaschii and Methanococcus igneus were studied to determine whether modification patterns reflect the close phylogenetic relationships inferred from small ribosomal subunit RNA sequences, and to examine modification differences associated with temperature of growth. Twenty-four modified nucleosides were characterized, including the complex tricyclic nucleoside wyosine characteristic of position 37 in tRNA(Phe) and known previously only in eukarya, plus two new wye family members of presently unknown structure. The hypermodified nucleoside 5-methylaminomethyl-2-thiouridine, reported previously only in bacterial tRNA at the first position of the anticodon, was identified by liquid chromatography-electrospray ionization mass spectrometry in four of the five organisms. The ribose-methylated nucleosides, 2'-O-methyladenosine, N(2),2'-O-dimethylguanosine and N(2),N(2),2'-O-trimethylguanosine, were found only in hyperthermophile tRNA, consistent with their proposed roles in thermal stabilization of tRNA.
