Geometrically Realistic Macro-Scale Model for Multi-Scale Simulations of Catalytic Filters for Automotive Gas Aftertreatment

This paper is part of a research focused on simulating (i) the catalytic conversion of environment endangering gases, and (ii) trapping of the particulate matter in automotive exhaust gas aftertreatment. Historically, the catalytic conversion and the filtration of soot particles were performed in independent devices. However, recent trend is to combine the catalytic converter and soot filter into a single device, the catalytic filter. Compared to the standard two-device system, the catalytic filter is more compact and has lower heat losses. Nevertheless, it is highly sensitive to the catalyst distribution. This study extends our recently developed methodology for pore-scale simulations of flow, diffusion and reaction in the coated catalytic filters. The extension consists of enabling data transfer from macroto pore-scale models by preparing geometrically realistic macro-scale CFD simulations. The simulation geometry is based on XRT scans of real-life catalytic filters. The flow data from the newly developed macro-scale model are mapped as boundary conditions into the pore-scale simulations and used to improve the estimates of the catalytic filter filtration efficiency.
Storing and querying fuzzy RDF(S) in HBase databases

The Resource Description Framework (RDF) and RDF Schema (RDFS) recommended by World Wide Web Consortium (W3C) have been used for meta‐data management on the Web. With the rapid development of Web‐based applications, the growth of RDF(S) data is increasing dramatically. In the context of open Web, uncertainty naturally arises in RDF and RDFS (RDF(S) in short). To manage large‐scale fuzzy RDF(S) data efficiently and effectively, we propose, in this paper, a fuzzy RDF(S) storage schema with fuzzy HBase databases (FHDBs). On the basis, we investigate how to query in FHDBs. We propose a set of query algorithms. We implement a prototype system to demonstrate the feasibility of our approach.
CHOpinionMiner: An unsupervised system for Chinese opinion target extraction

Opinion target extraction (OTE) is an important task in fine‐grained sentiment analysis field, which focuses on the identification of the targets of users' opinions or sentiments from online reviews. Existing approaches to OTE are mainly based on unsupervised rule‐based methods or supervised machine learning methods. However, the latter needs a large number of labeled samples to train their models and lack of labeled corpus limits the research progress on OTE of Chinese. In this paper, we proposed a novel unsupervised and domain independent system called CHOpinionMiner. First, noun phrases are extracted as candidate opinion targets based on phrase structure grammar, then the syntactic paths of the candidate opinion targets and the opinion words in one opinionated sentence are extracted. After that, the legal paths, or rather, the opinion targets‐opinion lexicon pairs that are syntactically associated are selected according to the syntactic rules. Finally, not only the formal targets but also the orientations are obtained. Experiments on data sets consisting of microblog topics and product reviews demonstrate that our approach outperforms the existing state‐of‐the‐art methods.
Multistage origin of dunite in the Purang ophiolite, southern Tibet, documented by composition, exsolution and Li isotope characteristics of constituent minerals

Abstract. The Purang ophiolite, which crops out over an area of about 650 km 2 in the western Yarlung–Zangbo suture zone, consists chiefly of mantle peridotite, pyroxenite and gabbro. The mantle peridotite is comprised mainly harzburgite and minor dunite. Locally, the latter contains small pods of chromitite. Pyroxenite and gabbro occur as veins of variable size within the peridotite; most of them strike northwest, parallel to the main structure of the ophiolite. Three types of dunite occur in the Purang ophiolite: dunite that envelopes podiform chromitite (1) and lenses of dunite with either Cr-rich spinel (2) or Cr-poor spinel (3) in a harzburgite host. The constituent minerals of dunite envelopes around podiform chromitite are similar in composition to those of transition-zone dunite ( Fo91.01−91.87 in olivine; Cr / ( Cr + Al ) (Cr#) =41.5 –47.0 and Mg / ( Mg + Fe 2 + ) (Mg#) =58.9 –63.0 in Cr-spinel). Forsterite contents in olivine decrease from type 2 lenses with Cr-rich spinel (91.9–93.0) to type 1 dunite enveloping chromitite (91.7–93.7) to type 3 lenses with Cr-poor spinel (95.3–96.0). Similarly, Cr# in spinel decreases from type 2 (66.9–67.9) to type 1 (41.5–47.0) to type 3 (19.8–20.6). In addition, Al2O3 in clinopyroxene is highest in type 2 (3.48–5.24 wt %) and decreases to type 1 (1.56–3.29 wt %) and type 3 (0.78–0.86 wt %). Olivine in type 1 dunite enveloping podiform chromitite has Li concentrations and δ7Li values of 1.48–1.71 ppm and 6.19 ‰–7.98 ‰, respectively. Type 2 dunite lenses with Cr-rich spinel contain olivine with Li =0.98 –1.64 ppm and δ7Li =6.77 ‰–10.99 ‰. The type 3 dunite lenses with Cr-poor spinel show the highest values of Li =0.94 –1.40 ppm and δ7Li =10.25 ‰–14.20 ‰. Exsolution lamellae of clinopyroxene and magnetite occur as oriented intergrowths in olivine of type 3 dunite lenses with Cr-poor spinel. We suggest that the Purang ophiolite developed during two main stages of formation. In the first stage, abyssal peridotites formed in a mid-ocean-ridge environment. During the second stage, hydrous high-Mg boninitic melts were produced by high degrees of partial melting in a supra-subduction zone mantle wedge, which reacted with peridotite to form type 2 dunite pods with high-Cr# spinel. At lower degrees of partial melting in the same mantle wedge, Al-rich melts were produced, which reacted with peridotite to form type 3 dunite pods that contain low-Cr# spinel. These Al-rich melts were also relatively rich in Ti4+ , Ca2+ and Fe3+ , which were incorporated into the olivine structure by appropriate substitutions. During cooling, these elements exsolved as lamellae of magnetite and clinopyroxene.
Enhancement in dielectric and optical properties of La 1-x Ce x FeO 3 nanoparticles

La1-xCexFeO3; 0 ≤ × ≤ 0.15 nanoparticles were prepared in single phase using flash combustion technique. The crystalline structure and morphology of the investigated samples were researched through XRD and HRTEM. As a result, the dielectric constant of LaFeO3 was enhanced by Ce3+ ion substitution due to some the Ce3+ ions changes its valence to Ce4+ ions. The conduction mechanism in La1-xCexFeO3 samples is the small polaron (SP) tunneling. The type of optical transition is direct allowed transition and the band gap values are in the range of (2.8–1.89 eV). / values of La0.90Ce0. 10FeO3 decreases by increasing the external applied pressure at different frequencies. © 2019 The Authors.

Stabilization method for improving the condition number of the matrix of system of equations under the Cartesian Grid Finite Element Method

When using methods under the umbrella of Fictitious Domain such as the Cartesian Grid Finite Element Method (cgFEM) [1] to solve the linear elastic problem, some nodes of the mesh fall outside of the physical domain (pathological nodes), having a low associated stiffness in Figure 1: Example of a pathological node (red) with the proposed stabilization scheme. comparison with those located within the physical domain, as can be seen in Figure 1. This issue, typical of Fictitious Domain methods, leads to a deficient condition number of the matrix of the system of equations, making difficult the use of iterative solvers for large problems. Some authors proposes the modification of the Cartesian mesh structure [2] by forming aggregates while others propose the use of implicit domain extensions [3]. In this work, in order to preserve the Cartesian structure of the mesh, a new formulation for the stabilization problem is proposed. The formulation consist of penalizing the free movement of those nodes by an smooth extension of the solution of the interior of the domain, by means of a post-process of the solution via a displacement recovery technique. Graphically the proposed stabilization can be considered as an spring that anchors the node and a force that compensates the reaction of the spring, as shown in Figure 1, thus keeping the convergence properties of the problem. The numerical results show an improvement of the condition number, a decreasing in the number of iterations of the iterative solver while preserving the problem accuracy.

The recent state and variability of the carbonate system of the Canadian Arctic in the context of ocean acidification

Abstract. Ocean acidification driven by the uptake of anthropogenic CO2 by the surface oceans constitutes a potential threat to the health of marine ecosystems around the globe. The Arctic Ocean is particularly vulnerable to acidification due to its relatively low buffering capacity and, thus, is an ideal region to study the progression and effects of acidification before they become globally widespread. The appearance of undersaturated surface waters with respect to the carbonate mineral aragonite (ΩA
Effect of Vented and Closed Abutments on Peri-Implant Soft and Hard Tissues - Clinical and Radiographic Assessment

Excess cement found on tooth-retained restorations with healthy periodontal tissues present few if any problems. The cement-retained implant restoration may be more vulnerable to the effects of cement entering the soft tissues and residual excess cement on the implant restoration when compared to a tooth. It has been hypothesized that an open/hollow abutment may provide an internal reservoir for cement.Materials and methods: The patients included in the study were divided into two groups according to the abutment design that was used after implant placement; closed abutment group (CA) where 7 crowns were cemented on closed abutments vented abutment group (VA) where 7 crowns were cemented on vented abutments. |Re-examination was scheduled 3, 6 and 12 months after crown cementation. Periodontal assessment included Bleeding Index (BI) and Probing depth (PD). Bone height measurements were performed using cone beam computed tomography to measure the marginal bone loss.Results: Considering different intervals of the follow-up period, the differences in BI and PD between tested groups (vented and closed abutments) were statistically non-significant (p>0.05), but there was a statistically significant increase in PD for comparison between PD at different time periods in each group after 6 months as well as from 6 months to 12 months. After 3, 6 as well as 12 months, Group CA showed statistically significantly higher mean amounts of bone loss than Group VA.Conclusions: (1) Vented abutments exhibit better soft tissue response and less marginal bone loss when compared to closed abutments through one year follow up. (2) Soft tissue response and marginal bone loss associated with both abutment designs were within the normal health limits after one year follow up period of the study.
WAKE-UP-WORD SYSTEM USING SPHINX-4

— Many techniques have focused on improving the accuracy of speech recognition in General ASR systems, which are better known as Large-Vocabulary Continuous Speech Recognition systems or General ASR systems (General ASR). Some other approaches have focused on Wake-Up-Word ASR systems (WUW ASR), which are similar to Key-Word spotting. One important aspect of WUW ASR systems is the ability to discriminate the specific word or phrase used only in an alerting context and not in other, referential contexts. However, the aim of this paper is to evaluate the WUW approach by implementing a new WUW ASR system that can be used to recognize between the word in alerting context or referential contexts. Furthermore, the new ASR system will be able to reduce the number of false alarms in the devices and applications that use the speech commands to activate the devices and applications.
A Reﬂ ective Approach to Digital Technology Implementation in Language Teaching: Expanding Pedagogical Capacity by Rethinking Substitution, Augmentation, Modiﬁ cation, and Redeﬁ nition

As the number of language instructors seeking to implement digital technologies in their teaching continues to grow, so does the need for direction with regard to making pedagogically sound decisions concerning digital tool use. One popular and useful guide for considering the educational potential of digital technologies has been Puentedura’s (2006) Substitution-Augmentation-Modiﬁ cation-Redeﬁ - nition (SAMR) model, with its four levels of progressive technological integration. However, the degree of technological integration truly possible or even desirable for individual teachers in their given context depends on a number of complex, interrelated, largely non-technological factors, including implementation motives, pedagogical purview, educational philosophy, theory of learning, teaching style, and situational constraints. Generally unconscious, these factors often go ignored, leaving teachers susceptible to technological decisions that can lead them to lose their prescribed pedagogical focus or unwi(cid:308) ingly contradict their core professional beliefs. After a brief, situated overview of the SAMR model, this article introduces and illustrates a ﬁ ve-stage SAMR-embedded reﬂ ective approach to systematically eliminating irrelevant, unacceptable, and unfeasible instructional uses of technology and, thereby, revealing potential for expanding pedagogical capacity in language teaching.

Analyzing Player Proﬁles in Collectible Card Games

Collectible Card Games (CCGs) are experiencing a formidable growth in recent years, especially in regard to their digital incar-nations. In addition, understanding how players react to the various aspects of those games is of fundamental importance for designers and companies to provide new titles, mechanics, and expansion decks. In particular, comprehension about how players enjoy CCGs play a key role in understanding how these games can be improved and maintained. In this paper, we carried out analyzes on data collected from users in order to ﬁgure out player proﬁles and preferences in this segment. Our experiments are based on multivariate analysis methods applied to the responses collected from an opinion survey. Our experimental results show these are capable tools to explore subtle, non-trivial characteristics of the data. We obtained two clear player proﬁles and their preferences.
I2-ASYMPTOTICALLY LACUNARY STATISTICAL EQUIVALENCE OF WEIGHT g OF DOUBLE SEQUENCES OF SETS

Theory of statistical convergence was firstly originated by Fast [6]. This concept was extended to the double sequences by Mursaleen and Edely [14]. Lacunary statistical convergence was defined by Fridy and Orhan [7]. Çakan and Altay [3] presented multidimensional analogues of the results presented by Fridy and Orhan [7]. The idea of I-convergence was introduced by Kostyrko et al. [11] as a generalization of statistical convergence which is based on the structure of the ideal I of subset of the set of natural numbers. Recently, Das et al. [5] introduced new notions, namely I-statistical convergence and Ilacunary statistical convergence by using ideal. The notion of lacunary ideal convergence of real sequences was introduced in [23]. Das, Koystrko, Wilczynski and Malik [4] introduced the concept of Iconvergence of double sequences in a metric space and studied some properties of this convergence. Belen et al. [2] introduced the notion of ideal statistical convergence of double sequences, which is a new generelization of the notions of statistical convergence and usual convergence. Kumar et al. [12] introduced I-lacunary statistical convergence of double sequences. Nuray and Rhoades [15] extended the notion of convergence of set sequences to statistical convergence and gave some basic theorems. Ulusu and Nuray [24] defined the Wijsman lacunary statistical convergence of sequence
INVESTIGATION OF THE PERCEPTION OF POLITENESS IN SMALL GROUP FORMATIONS GROUP NUMBER 15

Studying crowds have come to be a complex matter and many factors need to be taken in consideration. Earlier research have shown that some affective expressions are as efficient as facial expressions, if not better (Kleinsmith, A & Bianchi-Berthouze, N, 2013). In this psychophysical study ​we evaluated the perception of a small crowd of 3 individuals in F-formation. More specifically the perceiving of politeness/impoliteness in a person’s body orientation in relation to other members of a group and from that determine the rotation threshold of perceptual politeness. The study used yellow stick figures as virtual characters, not specified by gender, age, cultural background, height or relation between them. Subjects were separately presented with a stimuli in which he/she was a part of a group formation where one virtual character was rotated. Different stimulus were presented in a randomized order where each stimuli had a different rotation angle. The subject was then given the task to rate the perceived politeness of each stimuli. ​Our results suggests that rotation of a character in a group did have an impact on the perceived politeness.
A historical analysis of Debian package conﬂicts

—Users and developers of software distributions are often confronted with installation problems due to conﬂicting packages. A prototypical example of this are the GNU Linux distributions such as Debian. While the problem of co-installability of Debian packages has been studied in the past, little is known about how this problem evolves over time. In this article, we present preliminary results of an empirical analysis of co-installability problems of individual packages throughout seven years of history of the Debian distribution
The use of subtractive hybridization to obtain a DNA probe specific for <Emphasis Type="Italic">Pseudomonas solanacearum</Emphasis> race 3

Pseudomonas solanacearum, the causal agent of bacterial wilt, has been classified into three races based on host range and into five biovars based on physiological properties. Strains of race 3 belong exclusively to biovar 2 and primarily affect potatoes. Although this race is thought to have originated in the Andean highlands, it has unusual physiological properties that make it a potential threat to potatoes grown at the cooler latitudes worldwide. Consequently, there is need for a rapid and sensitive method for detection of race 3 strains. We have used subtractive hybridization to enrich for race 3-specific DNA sequences in total race 3 genomic DNA, and thereby obtained a 2 kb clone homologous to DNA from all 28 race 3 strains tested, but with only five of 90 non-race 3 strains. In addition, two larger regions of the genome, containing a minimum of 23 kb of DNA, are also specific for race 3. Deletion of this DNA did not affect virulence. This race 3-specific DNA is a potentially useful diagnostic tool for the detection of race 3 strains.

The purpose of this study is to examine some factors (Academic self-efficacy, motivation, Locus of control and gender) associated with academic dishonesty. 250 participants of both genders (76% men and 24 % women) from 17 to 21 years old were selected using the purposive sampling technique. The instruments used were the General self-efficacy scale, the academic motivation scale, the locus of academic control scale and the academic dishonesty scale. The correlation coefficient, regression analysis, and t-tests were carried out. Academic self-efficacy, locus of control and motivation related to academic dishonesty. There was a gender difference on academic self-efficacy, locus of control and academic dishonesty. The results and implications are further discussed.
Genetic Stock Identification of Fraser River Pink Salmon: Methodology and Management Application

Genetic stock identification (GSI) is used by the Pacific Salmon Commission (PSC) to estimate contributions of Fraser River pink salmon (Oncorhynchus gorbuscha) to mixed-stock fishery catches. GSI provides the basic stock composition data needed by the Fraser River Panel to achieve its mandates of accounting for Fraser River pink salmon wherever they are caught and managing fisheries targeting on these stocks within the Fraser River Panel Area. The main components of the GSI program are discussed, including: (1) collection and electrophoretic analysis of tissue samples of pink salmon from spawning grounds of major, representative stocks; (2) creation of baselines after statistical analysis of the stock-specific genetic data; (3) planning and execution of the inseason GSI program; (4) application of the stock composition estimates for fisheries management; and (5) post-season analyses of stock contribution estimates made during the in-season period. Over the five cycle-years (1987, 1989, 1991, 1993, and 1995) that the GSI program has been conducted, it has aided the Panel in achieving catch and escapement goals for Fraser River pink salmon and has provided useful information for in-season run size estimation and determination of migration routes and timing of these fish.
