On the Relationship Between Grain-Boundary Character Distribution and Intergranular Corrosion (1996)

Intergranular corrosion can under severe conditions lead to “grain-dropping” which results in significant material loss. It has been demonstrated that grain boundaries described by low-Σ CSL misorientations are more resistant to corrosion, cracking (SCC), and sliding (creep) than “general” boundaries, and that the frequency of these “special” boundaries can be enhanced offering the possibility of producing materials with improved bulk corrosion and creep properties. This contribution presents a model for predicting the effect of “special” boundaries on the extent of gross wastage from grain-dropping. For any grain to be ejected from the matrix, all of its bounding interfaces must be fully compromised. Assuming “special” grain boundaries are immune to corrosion and considering a material containing hexagonal prism grains with a diameter and length, d, it can be shown that the probability, X, of observing grain-dropping at a depth, L, through the material thickness is related to the “special” boundary fraction, F sp , by:
Study on the Modification Mechanism of RPRS Modified Asphalt (2018)

In this paper, the penetration system and PG classification system were used to analyze the modifying effects of RPRS on asphalt. The basic physical properties of RPRS modifier were showed to analyze the modification mechanism. RPRS showed the feature of plastic hardness during the temperature of 50~110, and became liquid above 110. Further researches on the modification mechanism were conducted through DSC method, IR spectra analysis and dynamic mechanical analysis. An obvious endothermic process was found when RPRS was at the temperature of 110~110, indicating the transformation of viscous-elastic state, which was similar to the analysis of basic physical properties. Compared with PEW, a sharp attenuation was found in the transmittance of RPEW, indicating the aging of RPEW. After being mixed with CRM and SBR, the transmittance of RPRS could be recovered.
Web Service Discovery: Adding Semantics through Service Request Expansion and Latent Semantic Indexing (2007)

Semantic Web technology is a promising first step for automated service discovery. Most current approaches for web service discovery cater to semantic web services, i.e., web services that have semantic tagged descriptions. It is difficult, however, to expect all new services to have semantic descriptions associated. Furthermore, the descriptions of the vast majority of already existing services do not have explicitly associated semantics. There are also severe restrictions on the prospective conversion of existing, non-semantic, descriptions, e.g., Web service description language (WSDL), to corresponding semantic descriptions, e.g., OWL-based Web service ontology (OWL-S). In this paper we present a novel approach for web service discovery that combines ontology linking with latent semantic indexing (LSI). The basic idea is to build the service request vector according to the domain ontology, have the training set of the LSI classifier based on features extracted from selected WSDL files, and finally project the description vectors and the request vector and utilize the cosine measure to determine similarities and to retrieve relevant WSDL service descriptions.

A Microprocessor-Based Current Controller for SCR-DC Motor Drives (1980)

A new current controller for a three-phase full-wave silicon controlled rectifier (SCR) bridge, supplying a separately excited armature-controlled dc motor driving an inertial load is developed. The controller operates in two modes, one applicable when the motor armature current is continuous, the other when it is discontinuous. The current controller is then used in speed or position control of a dc motor. The control algorithms are simple and may easily be implemented in real time on a microcomputer.
Cis/trans isomerization of fatty acids as a defence mechanism of Pseudomonas putida strains to toxic concentrations of toluene (1994)

Defence mechanisms of three Pseudomonas putida strains growing in the presence of toluene up to 50% (v/v) were investigated. The three strains reacted to toxic concentrations of toluene by accumulating trans unsaturated fatty acids in the membrane instead of the cis isomers. The membranes of the toluene-adapted cells possessed a higher trans/cis ratio and had a higher lipid-ordering since the transition temperature was about 7 centigrade degrees higher compared to the non-adapted cells.

Aktionsprimitive: Ein universelles Roboter-Programmierparadigma (Manipulation Primitives: An Universal Robot Programming Paradigma) (2005)

Abstract Heutige Robotersysteme können auf unvorhergesehene Ereignisse kaum reagieren. Ungenauigkeiten und kleinste Änderungen der Aufgabenstellung verursachen häufig Störungen und damit erheblichen Modifikationsaufwand. Diese Unflexibilität kann durch geeignete Sensorik gemindert werden. Deren Integration erweist sich allerdings häufig als sehr schwierig und führt oft zu unflexiblen Speziallösungen. Als Abhilfe wird in diesem Artikel das Programmierparadigma mit Aktionsprimitiven vorgestellt. Es erlaubt die Definition von sensorgeführten und sensorüberwachten Roboterbewegungen auf Programmierebene. Die dazu benötigten Steuer- und Regelungsfunktionalitäten werden automatisch in die Robotersteuerung eingebunden. Die zugehörige Steuerungs- und Softwarearchitektur wird ebenfalls erläutert. Die Anwendung des Programmierkonzepts wird anhand von Beispielen gezeigt.
Multidimensional Artificial Field Embedding With Spatial Sensitivity (2013)

Multidimensional embedding is a technique useful for characterizing spectral signature relations in hyperspectral images. However, such images consist of disjoint similar spectral classes that are spatially sensitive, thus presenting challenges to existing graph embedding tools. Robust parameter estimation is often difficult when the image pixels contain several hundreds of bands. In addition, finding a corresponding high-quality lower dimensional coordinate system to map signature relations remains an open research question. We answer positively on these challenges by first proposing a combined kernel function of spatial and spectral information in computing neighborhood graphs. We further adapt a force field intuition from mechanics to develop a unifying nonlinear graph embedding framework. The generalized framework leads to novel unsupervised multidimensional artificial field embedding techniques that rely on the simple additive assumption of pair-dependent attraction and repulsion functions. The formulations capture long-range- and short-range-distance-related effects often associated with living organisms and help to establish algorithmic properties that mimic mutual behavior for the purpose of dimensionality reduction. In its application, the framework reveals strong relations to existing embedding techniques, and also highlights sources of weaknesses in such techniques. As part of evaluation, visualization, gradient field trajectories, and semisupervised classification experiments are conducted for image scenes acquired by multiple sensors at various spatial resolutions over different types of objects. The results demonstrate the superiority of the proposed embedding framework over various widely used methods.

Every Moment Counts: Dense Detailed Labeling of Actions in Complex Videos (2015)

Every moment counts in action recognition. A comprehensive understanding of human activity in video requires labeling every frame according to the actions occurring, placing multiple labels densely over a video sequence. To study this problem we extend the existing THUMOS dataset and introduce MultiTHUMOS, a new dataset of dense labels over unconstrained internet videos. Modeling multiple, dense labels benefits from temporal relations within and across classes. We define a novel variant of long short-term memory (LSTM) deep networks for modeling these temporal relations via multiple input and output connections. We show that this model improves action labeling accuracy and further enables deeper understanding tasks ranging from structured retrieval to action prediction.
Synthesis of the Salmonella Type E<sub>1</sub> Core Trisaccharide as a Probe for the Generality of 1-(Benzenesulfinyl)piperidine/Triflic Anhydride Combination for Glycosidic Bond Formation from Thioglycosides (2002)

A synthesis of a chromogenic glycoside of the Salmonella anatum group E(1) core trisaccharide is presented in which all three glycosidic bonds, a 1,2-cis-equatorial, a 1,2-trans-axial, and a 1,2-trans-equatorial linkage representing three of the four main classes of glycosidic bond, are formed with thioglycoside donors activated under a single set of conditions by the combination of 1-(benzenesulfinyl)piperidine and trifluoromethanesulfonic anhydride. 2,3-O-Carbonyl- and 2,3-O-isopropylidene-alpha-L-rhamnopyranosyl thioglycosides are found to be highly alpha-selective rhamnosyl donors under these conditions.
A Multiple Beam Synthetic Aperture Radar Design Concept for Geoscience Applications (1983)

The multiple beam synthetic aperture radar (SAR) has been presented as a superior alternative to conventional side-looking SAR designs for mapping earth resources from space. The multiple beam approach provides wide swath coverage at nearly constant incident angle while conserving peak power. These desirable system characteristics, however, are realized at the expense of additional signal processing. A design example illustrates the attributes of the multiple beam SAR in comparison to a conventional side-looking system. A novel beam formation processing architecture is shown which can provide simultaneous range compression while forming the beams. A configuration for the image formation processor is proposed and analyzed in terms of an analog implementation which can perform Doppler compression at speeds faster than real time. These implementation schemes indicate that on-board processing for the multiple beam SAR is possible.
Immunostaining of human melanomas by a monoclonal antibody to B700 mouse melanoma antigen (1996)

Previous studies have shown that B700, an albumin-like murine melanoma antigen, has a human homologue termed H700. Polyclonal antibodies to B700 also bind to all cultured human, swine and hamster melanoma cells, suggesting that B700 is a "pan-melanoma" antigen. The objects of this investigation were: (a) to determine if 2-3-3, a monoclonal antibody to B700, can be used to identify human melanomas in formalin-fixed, paraffin-embedded tissues, and (b) to determine the specificity and potential diagnostic value of 2-3-3. Forty-eight of the 49 human melanomas, including spindle melanoma cells, stained positively, as did five of the eight pigmented naevi including cellular spindle naevi. Twenty-six of the 32 human non-melanomatous lesions were negative for 2-3-3 staining (weakly positive on one breast carcinoma and positive on five neural tumours). These results indicate that 2-3-3, a monoclonal antibody to the mouse melanoma antigen B700, can be used to identify H700 in archival specimens. 2-3-3 may have an advantage over HMB45, which is the most commonly used antibody for melanoma diagnosis, because of its immunoreactivity with spindle melanocytic lesions. Antibodies to B700 may prove to be a useful adjunct in the diagnosis of human melanoma and related lesions.
Experimentally-Based Empirical Foam Modeling (2014)

Abstract This paper presents fine-scale numerical simulations and mathematical analysis of the empirical foam model for representing foam-surfactant flow in a vertical column of laboratory sand-pack based on two sets of experimental data conducted at variable total velocities and variable foam qualities.The empirical foam model of CMG-STASRS is used for parametric matching of laboratory data, and relevant foam parameters are calibrated.The paper discusses experimental setup, procedure and measurements to provide apparent foam viscosity data needed for foam modeling. In the first set of lab tests, foam quality is constant and the total fluid superficial velocity varies for foam shear thinning effect; while in the second tests, foam quality is varied at a fixed total superficial velocity to capture different flow regimes and foam dry-out characteristics.Employing an analytical method and 1-D numerical simulations of the foam flow in the sand-pack, the empirical foam model is tuned to the first data set of variable velocity and used to predict the second data set of variable quality as a consistency check.The model predictions for the second data set as well as the associated sensitivity analysis prove that the foam modeling procedure of this paper is unique and applicable for large-scale predictions.
Selective Formation of Polycarbonate over Cyclic Carbonate: Copolymerization of Epoxides with Carbon Dioxide Catalyzed by a Cobalt(III) Complex with a Piperidinium End‐Capping Arm (2006)

Ringbildung vermieden: Die Copolymerisation terminaler Epoxide mit CO2 wurde mit einem Cobalt(III)-Komplex untersucht, der einen Piperidinium- und einen Piperidinyl-Arm enthält (siehe Schema; DME=1,2-Dimethoxyethan). Das Katalysatorsystem liefert die Copolymere selektiv, ohne dass dabei Verunreinigungen in Form cyclischer Carbonate gebildet werden, und dies selbst bei einem hohen Epoxidumsatz (>99 %).
Unique Inhibitory Effect of 1-(2′-Deoxy-2′-fluoro-β-l-arabinofuranosyl)-5-methyluracil 5′-Triphosphate on Epstein-Barr Virus and Human DNA Polymerases (1998)

1-(2'-Deoxy-2'-fluoro-beta-L-arabinofuranosyl)-5-methyluracil (L-FMAU) was shown to have potent antiviral activity against Epstein-Barr virus (EBV) without any cellular toxicity at concentrations up to 200 microM (Yao et al., Biochem Pharmacol 51: 941-947, 1996). The 5'-triphosphate of L-FMAU was not a substrate for EBV or cellular DNA polymerases, but could inhibit the elongation reaction, 3'-to-5' exonuclease activity, and nucleotide turnover catalyzed by EBV DNA polymerase. DNA synthesis catalyzed by human DNA polymerases was inhibited to a lesser extent. The inhibition pattern of EBV DNA polymerase by L-FMAU-5'-triphosphate (L-FMAU-TP) was consistent with an uncompetitive mechanism when dNTP or template-primer were used as the variable substrates. The Ki values were 38+/-10 microM for the elongation reaction, and about 50+/-10 microM for both nucleotide exchange and 3'-to-5' exonuclease reactions, values that were 10-20 times less than that for GMP. L-FMAU-TP is the first nucleoside 5'-triphosphate shown to have such unique behavior toward DNA polymerases. EBV DNA polymerase could be one of the targets for the inhibitory effect of L-FMAU-TP on EBV replication.
Percutaneous transluminal dilatation of the iliac artery: long-term results. (1985)

One hundred fifty-four patients with stenosis of the iliac artery underwent percutaneous transluminal angioplasty (PTA). These patients were followed for 1-7 years. The long-term results of the PTAs were analyzed by computer, and life tables were generated for dilatations of the iliac arteries with unimpaired flow and for those with an obstruction in the outflow tract. The accumulative 7-year patency rate was 90%, which agrees with other reports. This study demonstrates that the long-term results of PTA of iliac arterial stenoses are competitive with reconstructive vascular surgery. PTA should be the treatment of choice in patients with iliac arterial stenoses.
Bringing Existing High Efficiency Buildings Back Into Line (2009)

Opened in 2003, the CSIRO Energy Centre was designed to be a showcase of the latest renewable and energy efficiency technologies of its day. Boasting over 220 kW of onsite generation in addition to passive and active energy efficient design features, the site was originally envisaged to generate a significant portion of its energy requirements for energy efficiency and security. Six years on and with considerably higher occupancy levels than when commissioned, analysis of energy data has shown degradation in performance over time, with the building not able to achieve its original design intent. To identify key areas for improvement, a level 3 energy audit was conducted, revealing a number of opportunities for reducing energy consumption with relatively short payback periods. These opportunities are discussed in detail, in addition to a number of advanced building control strategies and technologies that have been developed and implemented in-house. Future projections of building energy consumption and performance assuming implementation of the opportunities and control strategies discussed are also presented. These projections show that with relatively inexpensive capital investment, the Energy Centre has the potential to surpass its original energy performance benchmark, even with increased occupant density and operational load, thus restoring it to a leading high-efficiency facility.
Empowerment through photo novella: portraits of participation (1995)

Photo novella does not entrust cameras to health specialists, policymakers, or profes-sional photographers, but puts them in the hands of children, rural women, grassroots workers, and other constituents with little access to those who make decisions over their lives. Promoting what Brazilian educator Paulo Freire has termed &quot;education for critical consciousness, &quot; photo novella allows people to document and discuss their life conditions as they see them. This process of empowerment education also enables community members with little money, power, or status to communicate to policymakers where change must occur. This paper describes photo novella’s underpinnings: empowerment education, feminist theory, and documentary photography. It draws on our experience implementing the process among 62 rural Chinese women, and shows that two major implications of photo novella are its contributions to changes in consciousness and in-forming policy. The camera is my tool. Through it I give a reason to everything around me.
X-Ray Stress Measurement of Hexagonal Polycrystals with (001) Fiber Texture. (1998)

A new method of X-ray measurements of tri-axial residual stresses was proposed for hexagonal polycrystals with the[001]fiber texture. The relation between X-ray strain and sin2 ψ is linear for the cases of the fiber axis perpendicular or parallel to the specimen surface, provided that there is no shear stress acting on the specimen surface. The in-plane stresses, σ11 σ22 and σ12 and the normal stress perpendicular to the specimen surface, σ33 can be determined from the slope and the intercept of the linear regression line for the relation between X-ray strain and sin2 ψ obtained for three different directions.
The Material Is the Machine (2005)

Efforts are under way to manufacture electromechanical devices at ever smaller sizes. However, standard semiconductor technology places limits on how small such machines can be. In their Perspective, Bhattacharya and James explain how martensitic materials--which can distort reversibly without any diffusion taking place--may overcome this problem. Theoretical studies and preliminary experiments suggest that such materials can act as machines themselves, without the need for complicated construction of moving parts in the device.

Data mining in education (2012)

Abstract Applying data mining (DM) in education is an emerging interdisciplinary research field also known as educational data mining (EDM). It is concerned with developing methods for exploring the unique types of data that come from educational environments. Its goal is to better understand how students learn and identify the settings in which they learn to improve educational outcomes and to gain insights into and explain educational phenomena. Educational information systems can store a huge amount of potential data from multiple sources coming in different formats and at different granularity levels. Each particular educational problem has a specific objective with special characteristics that require a different treatment of the mining problem. The issues mean that traditional DM techniques cannot be applied directly to these types of data and problems. As a consequence, the knowledge discovery process has to be adapted and some specific DM techniques are needed. This paper introduces and reviews key milestones and the current state of affairs in the field of EDM, together with specific applications, tools, and future insights. © 2012 Wiley Periodicals, Inc.

The Importance of Local Eosinophilia in the Surgical Outcome of Chronic Rhinosinusitis: A 3-Year Prospective Observational Study (2014)

The presence of eosinophils in tissue or airway secretions greatly increases the risk of recurrent disease in CRSwNP patients. The finding of tissue eosinophilia and EM provides valuable information regarding the increased likelihood of CRS recurrence after ESS, whereas the finding of FH does not.
