Abstract:

<p class="Default">Yorùbá numerals have been seen as one of the most interesting but quite complicated numeral system. In this paper we present the development of a web-based English to Yorùbá numeral translation system. The system translates English numbers both in figure and text to its standard Yorùbá form. The computational processes underlying both numerals were used to formulate the model for the work. Unified Modeling language (UML) and Automata theory was used for the system design and specification. The designed system was implemented using Google Web App Engine with support for python. The result of the system evaluation using mean opinion score approach shows that the system gives a recall of 100% on all the output considered.</p>

Abstract:

Handwritten numeral recognition has been an important area in the domain of pattern classification. The task becomes even more daunting when working with non-Roman numerals. While convolutional neural networks are the preferred choice for modeling the image data, the conception of techniques to obtain faster convergence and accurate results still poses an enigma to the researchers. In this paper, we present new methods for the initialization and the optimization of the traditional convolutional neural network architecture to obtain better results for Kannada numeral images. Specifically, we propose two different methods- an encoderdecoder setup for unsupervised training and weight initialization, and a particle swarm optimization strategy for choosing the ideal architecture configuration of the CNN. Unsupervised initial training of the architecture helps for a faster convergence owing to more task-suited weights as compared to random initialization while the optimization strategy is helpful to reduce the time required for the manual iterative approach of architecture selection. The proposed setup is trained on varying handwritten Kannada numerals. The proposed approaches are evaluated on two different datasets: a standard Dig-MNIST dataset and a custom-built dataset. Significant improvements across multiple performance metrics are observed in our proposed system over the traditional CNN training setup. The improvement in results makes a strong case for relying on such methods for faster and more accurate training and inference of digit classification, especially when working in the absence of transfer learning.

Abstract:

This paper introduces a sequence of λ-expressions modeling the binary expansion of integers. We derive expressions computing the test for zero, the successor function, and the predecessor function, thereby showing the sequence to be an adequate numeral system, i.e. one in which all recursive functions are lambda-definable. These functions can be computed efficiently; To this end, we introduce a notion of complexity that is independent of the order of evaluation.

Abstract:

To suppress airfoil flutter, a lot of control methods have been proposed, such as classical control methods and optimal control methods. However, these methods did not consider the influence of actuator faults and control delay. This paper proposes a new finite-time H∞ adaptive fault-tolerant flutter controller by radial basis function neural network technology and adaptive fault-tolerant control method, taking into account actuator faults, control delay, modeling uncertainties, and external disturbances. The theoretic section of this paper is about airfoil flutter dynamic modeling and adaptive fault-tolerant controller design. Lyapunov function and linear matrix inequality are employed to prove the stability of the proposed control method of this paper. The numeral simulation section further proves the effectiveness and robustness of the proposed control algorithm of this paper.

Abstract:

Micro-mould is a necessary and productive component for the development of MEMS. However, the machining of micro-mould parts with complex 3D surfaces becomes the key problem for the development of micro machinery. In the paper, a new machining technique was introduced to manufacture micro-mould parts. With a reverse engineering technique, point cloud data were acquired and reconstructed into a 3D model of micro mould part in a computer. The numeral control code for micro-machining was also processed with the help of micro-machining simulation. The machining experiment on micro-parts with complex 3D surfaces was conducted on self-developed micro machine tools with micro-diameter ball-end cutter. High quality micro mould parts with complex 3D surfaces were obtained under these micro-milling experiments. The results will provide a perspective resolution on the manufacturing of micro-mould parts with complex surfaces.

Full text

Abstract:

The dynamic model of overhead crane is highly nonlinear and uncertain. In this paper, Takagi-Sugeno (T-S) fuzzy modeling and PSO-based robust linear quadratic regulator (LQR) are proposed for anti-swing and positioning control of the system. First, on the basis of sector nonlinear theory, the two T-S fuzzy models are established by using the virtual control variables and approximate method. Then, considering the uncertainty of the model, robust LQR controllers with parallel distributed compensation (PDC) structure are designed. The feedback gain matrices are obtained by transforming the stability and robustness of the system into linear matrix inequalities (LMIs) problem. In addition, particle swarm optimization (PSO) algorithm is used to overcome the blindness of LQR weight matrix selection in the design process. The proposed control methods are simple, feasible, and robust. Finally, the numeral simulations are carried out to prove the effectiveness of the methods.

Abstract:

Abstract. Data scarcity is a major cause of substantial uncertainties in regional estimations conducted with model upscaling. To evaluate the impact of data scarcity on model upscaling, we introduce an approach for aggregating uncertainties in model estimations. A data sharing matrix was developed to aggregate the modeled uncertainties in divisions of a subject region. In a case study, the uncertainty in methane emissions from rice paddies on mainland China was calculated with a local-scale model CH4MOD. The data scarcities in five of the most sensitive model variables were included in the analysis. The national total methane emissions were 6.44–7.32 Tg, depending on the spatial resolution used for modeling, with a 95% confidence interval of 4.5–8.7 Tg. Based on the data sharing matrix, two numeral indices, IR and Ids, were also introduced to suggest the proper spatial resolution in model upscaling.

Abstract:

Thermophysiological comfort is known to play a primary role in maintaining thermal balance, which corresponds to a person’s satisfaction with their immediate thermal environment. Among the existing test methods, sweating torsos are one of the best tools to provide a combined measurement of heat and moisture transfer using non-isothermal conditions. This study presents a preliminary numerical model of a single sector sweating torso to predict the thermophysiological comfort properties of fabric systems. The model has been developed using COMSOL Multiphysics, based on the ISO 18640-1 standard test method and a single layer fabric system used in sportswear. A good agreement was observed between the experimental and numeral results over different exposure phases simulated by the torso test (R2 = 0.72 to 0.99). The model enables a systematic investigation of the effect of fabric properties (thickness, porosity, thermal resistance, and evaporative resistance), environmental conditions (relative humidity, air and radiant temperature, and wind speed), and physiological parameters (sweating rate) to gain an enhanced understanding of the thermophysiological comfort properties of the fabric system.

Abstract:

Abstract In the experiment described in the paper Noah Goodman & Andreas Stuhlmüller. 2013. Knowledge and im-plicature: Modeling language understanding as social cognition. Topics in Cognitive Science 5(1). 173–184, empirical support was provided for the predictive power of the Rational Speech Act (RSA) model concerning the interpretation of utterances employing numerals in uncertainty contexts. The RSA predicts a Bayesian interdependence between beliefs about the probability distribution of the occurrence of an event prior to receiving information and the updated probability distribution after receiving information. In this paper we analyze whether the RSA is a descriptive or a normative model. We present the results of two analogous experiments carried out in Polish. The first experiment does not replicate the original empirical results. We find that this is due to different answers on the prior probability distribution. However, the model predicts the different results on the basis of different collected priors: Bayesian updating predicts human reasoning. By contrast, the second experiment, where the answers on the prior probability distribution are as predicted, is a replication of the original results. In light of these results we conclude that the RSA is a robust, descriptive model, however, the experimental assumptions pertaining to the experimental setting adopted by Goodman and Stuhlmüller are normative.

Abstract:

As literate adults, we appreciate numerical values as abstract entities that can be represented by a numeral, a word, a number of lines on a scorecard, or a sequence of chimes from a clock. This abstract, notation-independent appreciation of numbers develops gradually over the first several years of life. Here, using functional magnetic resonance imaging, we examine the brain mechanisms that 6- and 7-year-old children and adults recruit to solve numerical comparisons across different notation systems. The data reveal that when young children compare numerical values in symbolic and nonsymbolic notations, they invoke the same network of brain regions as adults including occipito-temporal and parietal cortex. However, children also recruit inferior frontal cortex during these numerical tasks to a much greater degree than adults. Our data lend additional support to an emerging consensus from adult neuroimaging, nonhuman primate neurophysiology, and computational modeling studies that a core neural system integrates notation-independent numerical representations throughout development but, early in development, higher-order brain mechanisms mediate this process.

Abstract:

Total shoulder arthroplasty (anatomical or reversible) has gained considerable popularity, but the difficulty of installing the glenoid component determines the development of 30–50 % of mechanical complications and revision operations. To simplify glenoid installation, an individual tool of an unusual design is used. Objective. To show clinical case of individual modeling of a glenoid implant, made by 3D printing, for the patient with old fixed humeral dislocation. Methods. A 52-year-old patient complained of severe pain and impaired limb function 4 years after a fracture-dislocation of the left numeral head, that was not reduced. The difficulty was in the presence of a significant HillSachs impression and huge anterior glenoid defect, IV stage osteoarthritis. Results. To solve the problem, a three-dimensional modelof the scapula was built based on the results of computer tomography, and its plastic model was printed. Designed individual augment for glenosphere installation.Lateralization of the center of rotation by 5 mm and downward inclination of the glenosphere by 5° was performed in the implant. The implant stem channel and screw holes are modeled to pass through the most massive parts of the scapula. An individual tool has been developed for installing this component and drillings for the screws. During the surgical intervention, the prepared tools and implant allowed to install a revers total shoulder implant and obtain the nearest positive result. Conclusions. It is advisable to use three-dimensional modelling with 3D printing in cases of reversible shoulder arthroplasty for patients with old fixed humeral dislocation and significant glenoid defect.

Abstract:

Ceramic materials are widely used in impact safekeeping systems. Ceramic is a heterogeneous material; its characteristics depend considerably both on specifications of its ingredients and the material structure completely. The finite element method (FEM) can be a useful tool for strength computation of these materials. In this paper, the mechanical properties of the ceramic composites are investigated, and the mechanical performance modeling of fiber-fortified ceramic matrix composites (CMC) is expressed by the instance of aluminum oxide fibers in a matrix composite based on alumina. The starting point of the modeling is an infrastructure (primary cell) that contains a micromechanical size, the statistical analysis characteristics of the matrix, fiber-matrix interface, fiber, and their reciprocal influences. The numeral assessment of the model is done using the FEM. The numerical results of composite elastic modulus were computed based on the amount of the added fibers and the porosity was evaluated for empirical data of samples with a similar composition. Various scanning electron microscope (SEM) images were used for each sample to specify the porosity. Also, the unit cell method presumed that the porous ceramic substance is manufactured from an array of fundamental units, each with the same composition, material characteristic, and cell geometry. The results showed that when the material consists of different pores and fibers, the amount of Young’s modulus reduces with the increment of porosity. The linear correlation model of elasticity versus porosity value from experimental data was derived by MATLAB curve fitting. The experimental data from the mechanical test and numerical values were in good agreement.

Abstract:

In order to determine the most unfavorable condition of the steel box girder, ensure its stress and deformation in the safe state, the steel box girder bridge should apply the finite element analysis software to modeling analysis. At the same time, data calculation can provide the theoretical evidence for the factory manufacturing lines. The tender DB01 of the continuous bridge of the Hong Kong-Zhuhai-Macao Bridge provides the backdrop for this essay, using MIDAS/Civil 2012 to do numeral simulation analysis on the hoisting, and then analyzing the stress and deformation of the main beam at the different construction stages. The analysis reveals that the temporary maximum of a hinged steel box girder should be 47.5MPa in the process of construction which is allowed by the stress of the steel Q 345.And after the No.1 beam has been put in the right place and connected, the maximum displacement of the No.6 joint is 19.4mm downward. With the construction stage CS7 completed, the maximum downward displacement is 14.2mm. Making the stress free alignment is superposing the minus figure of the cumulative displacement on the basis of designed line. Each beam segment has been made according to the stress free alignment .Also, after field construction, the ideology of designed lines of the bridge will be brought into reality.

Abstract:

Abstract Background: Numeracy, defined as the ability to handle basic probability and numerical concepts including computation, estimation, logic, and problem solving, is an under-recognized component of health literacy. Numeracy has been shown to influence performance of health tasks in non-hemophilia populations. Little is known about numeracy in the hemophilia population. Since hemophilia treatment requires understanding of numerical concepts to manage factor replacement, it is likely that numeracy also influences performance of health tasks by patients with hemophilia. A greater understanding of numeracy status and the characteristics influencing numeracy in the hemophilia population may allow healthcare providers to better influence health task performance. The objective of this study is to explore numeracy in the hemophilia population using two different tests of numeracy and to evaluate characteristics that are associated with low numeracy. Methods: Using a cross-sectional design, adults with moderate or severe hemophilia A or B who spoke and read English were enrolled at their annual visit at the Emory/Children's Health Care of Atlanta Hemophilia Treatment Center (HTC). Numeracy was measured using the validated Schwartz Woloshin (SW) test requiring answers in words and the unvalidated stick figure test requiring answers using images. Subjects were considered numerate with the SW numeracy test if all three questions were answered correctly or with the stick figure numeracy test if all four questions were answered correctly. Demographic and socioeconomic characteristics collected included age, race, ethnicity, household income (more or less than $50,000), level of education completed (more or less than completion of college), and duration of time followed at this HTC. Clinical information including type and severity of hemophilia, history of viral infections, history of depression, and use of chronic medication were abstracted from the medical records. Descriptive statistics of each variable and bivariate associations between numerate status and each dependent variable were calculated. Multivariable modeling using logistic regression was performed using the validated SW numeracy test as the dependent variable. Results: Of 91 enrolled participants with complete data, all were men. Most had hemophilia A [n=82 (90%)] and severe disease [69 (76%)]. Median age was 34 years [interquartile range (IQR) 18]. Sixty-three (69%) were Caucasian; 5 (6%) were Hispanic; 55 (61%) reported income of <$50,000; 33 (36%) had received an undergraduate degree or higher. Median duration of time followed at the HTC was 17.0 years [IQR 18]. Twenty-four (26%) were HIV positive; 54 (59%) were HCV positive; and 19 (21%) had history of depression. Forty-one (45%) used at least one chronic medication other than factor replacement. Using the SW numeracy test, there were 22 (24%) participants who were numerate. Using the stick figure numeracy test, 60 (66%) were numerate. Only 20 (22%) of all the participants answered all seven questions correctly; two participants (2%) were numerate on the SW test but not on the stick figure test; 40 participants (44%) were numerate on the stick figure numeracy test but not on the SW test; 29 (32%) were not numerate on either test. On bivariable analysis, SW numeracy was associated with higher education (p<0.01), higher income (p=0.035), and the use of chronic medication (p=0.048). On multivariable analysis, after adjusting for age, race, and ethnicity, SW numeracy was associated with higher education (OR 6.21, 95% CI = 1.95-19.76), use of chronic medication (OR 4.31, 95% CI = 1.29-14.34), and less time followed at the HTC (OR 0.92, 95% CI = 0.86-0.97). Conclusion: Among patients with hemophilia, a significant proportion of patients were not numerate. Patients with less than a college education were more likely to not be numerate. Accordingly, many patients with less than a college education may struggle to understand basic numeracy concepts and this may influence their understanding of dosing, factor pharmacokinetics and probability. The impact of numeracy on health outcomes and the utility of the SW and stick figure numeracy tests to help guide patient-centered discussions that involve mathematical concepts are important areas of future research.

Abstract:

We consider the problem of modeling complex systems where little or nothing is known about the structure of the connections between the elements. In particular, when such systems are to be modeled by graphs, it is unclear what vertex degree distributions these graphs should have. We propose that, instead of attempting to guess the appropriate degree distribution for a poorly understood system, one should model the system via a set of sample graphs whose degree distributions cover a representative range of possibilities and account for a variety of possible connection structures. To construct such a representative set of graphs, we propose a new random graph generator, Random Plots, in which we (1) generate a diversified set of vertex degree distributions and (2) target a graph generator at each of the constructed distributions, one-by-one, to obtain the ensemble of graphs. To assess the diversity of the resulting ensembles, we (1) substantialize the vague notion of diversity in a graph ensemble as the diversity of the numeral characteristics of the graphs within this ensemble and (2) compare such formalized diversity for the proposed model with that of three other common models (Erdos–Rényi–Gilbert (ERG), scale-free, and small-world). Computational experiments show that, in most cases, our approach produces more diverse sets of graphs compared with the three other models, including the entropy-maximizing ERG. The corresponding Python code is available at GitHub.

Abstract:

A hydraulic analysis of four stage axial power turbine cooling system was performed. A practical application of the existing algorithms of thermal-hydraulic analysis is considered. Reasonable flow-rate distribution among the cooling channels and cooling system air leakage waste reduction are discussed. An implementation of the rotor screen dividing rotor internal cavity into disk and shaft cavities is revealed as the best way to keep the flow-rate balance of cooling air in account of achievement simplicity.This paper also covers a key design concept that the structure of turbine shall be such as to promote good dissipation of heat from blades to disks by means of air flow passing through special channels between rotor parts.A turbine disks’ air-cooling system assessment importance is shown according to the aim of hot gas ingress prevention. It is given a brief description of known theoretical fundamentals on which the used thermal-hydraulic analysis computational method of modeling was based.Flow-rate distribution among the four stage axial power turbine disks’ air-cooling system is noted to be carried out by certain basic design choices such as labyrinth seals, fins and ledges. The most important factors on which the flow-rate distribution depends on are mentioned including a ratio of narrow section hydraulic area to channel section hydraulic area, hydraulic resistance and availability of centrifugal pressure between disks.Narrowing of cooling flow passage section causes air velocity increase and pressure reduction. Even though some recovery of velocity appears downstream the narrowing element, the pressure value changes its magnitude due to vortex losses. Therefore it makes possible to provide the required air distribution.The considered rotor screen structure confirmed its functionality in operating gas turbine plant and it is stated as achieved results. Numeral details of dealt analysis are omitted.Generally, the behavior of flow and heat exchange in area between rotating disks is classified as rather complicated and methods of its modeling are summarized to remain relevant question of further studies.

Abstract:

The aim of the study was to investigate changes of neuroblasts’ numeral destiny in rats’ olfactory bulb and rostral migratory stream after neurotoxic action in infant age.Material and methods. The distribution of DCX, a marker of immature neurons, was studied to reveal the dynamics of its expression in the evolutionary period of ontogenesis in olfactory bulbs and rostral migratory stream in 30, 60, 90, and 180-day-old rats. Modeling of neurotoxic effects was carried out by three times injections of capsaicin on the 30–32 day of life in a total dose of 120 mg/kg. The material for the study was sampled on the 15-, 30- and 60th days of the experiment. The marker was detected on parasagittal paraffin sections, taking into account the layers of the olfactory bulb. The numerical density of DCX+ neurons (pcs/mm2) and their part in the total number of cells were determined.Results. The standard age indicators of the numerical density of immature neurons and their share in the cell population, as well as similar indicators for two months after toxic effects, were established. The administration of toxic doses of capsaicin causes a massive death of mature neurons. Compensatory reaction manifested by activation of neurogenesis in the brain stem niches and an increase in the numerical density neuroblasts in the rostral stream.Conclusions. Activation of neurogenesis during neurodegeneration causes an increase in the number of DCX + neuronal progenitors in the olfactory bulb after 30 days after exposure and maintaining high levels until the end of observation.

Abstract:

Presently the losses of kinetic energy in the exhaust duct of low-pressure cylinder are considerable, since numerous spacer bars and directing plates are located inside. A fundamentally new approach is required to design the exhaust duct of LPC without internal elements in water passage and providing the decline of losses due to improvement of the diffuser form and collapsible chamber. The flow modeling in the considered exhaust duct design was carried out by the numerical RANS method with the SST turbulence model. To validate the CFD model, the results of the previous experimental studies of the basic design model were used. The comparison of the integral aerodynamic characteristics of the exhaust duct was carried out. For the basic variant of the exhaust duct, the variant without internal elements, and also for the variant without internal elements and with new geometry of the collapsible chamber, according to the results of the numeral experiment, distribution of pressure and vector fields of speeds in the exhaust nozzle are received and the integral parameters of the exhaust duct are defined. Advantage of the integral descriptions of the exhaust duct without internal elements and with a new form of collapsible chamber is proven. They are the coefficient of internal losses of the exhaust duct, the coefficient of kinematics unevenness of the stream, and the coefficient of repressuring in an axial-radial diffuser. It has been established that a new approach of geometry of the exhaust duct of LPC provides the improvement of their aerodynamic qualities when designing new high-powered steam-turbines to operate in TPP and NPP. The advantage of losses decline of energy in the exhaust duct is multiple, because the number of LPC streams in modern seam-turbines can amount up to eight.

Abstract:

This paper argues that modeling granularity and approximation (Krifka 2007; Lewis 1979) is crucial for capturing important aspects of the distribution and interpretation of adjectives and their modifiers, modulo certain differences between modified adjectives and numerals. In addition, the paper presents supporting experimental results with minimizers like 'slightly' and maximizers like 'completely'.

Abstract:

Feedforward neural networks trained by error backpropagation are examples of nonparametric regression estimators. We present a tutorial on nonparametric inference and its relation to neural networks, and we use the statistical viewpoint to highlight strengths and weaknesses of neural models. We illustrate the main points with some recognition experiments involving artificial data as well as handwritten numerals. In way of conclusion, we suggest that current-generation feedforward neural networks are largely inadequate for difficult problems in machine perception and machine learning, regardless of parallel-versus-serial hardware or other implementation issues. Furthermore, we suggest that the fundamental challenges in neural modeling are about representation rather than learning per se. This last point is supported by additional experiments with handwritten numerals.

Abstract:

This article attempts to measure the cognitive or informational load in interpreting by modelling the occurrence rate of the speech disfluency uh(m). In a corpus of 107 interpreted and 240 non-interpreted texts, informational load is operationalized in terms of four measures: delivery rate, lexical density, percentage of numerals, and average sentence length. The occurrence rate of the indicated speech disfluency was modelled using a rate model. Interpreted texts are analyzed based on the interpreter’s output and compared with the input of non-interpreted texts, and measure the effect of source text features. The results demonstrate that interpreters produce significantly more uh(m)s than non-interpreters and that this difference is mainly due to the effect of lexical density on the output side. The main source predictor of uh(m)s in the target text was shown to be the delivery rate of the source text. On a more general level of significance, the second analysis also revealed an increasing effect of the numerals in the source texts and a decreasing effect of the numerals in the target texts.

Abstract:

The article was created on the grounds of numerical modelling of shaped charges with a focus on the unconventional shape of their liners. The standard shaped charge of the “deep penetrating” type is equipped with a conical liner made of copper. Three various geometries of shaped charges featuring unconventional shape have been modelled and compared with the classical model of a shaped charge. The shaped charges have been compared for maximum pressure during detonation, cumulative jet velocity, kinetic energy gained and length of cumulative jet after 22 µs. The purpose of modelling shaped charges, featuring unconventionally formed liners, was to check whether they are able to improve the perforation job parameters in oil and gas wells. Perforation of the borehole is a critical job, enabling the initiation of hydrocarbons production from a specific reservoir. The job consists in making series of channels perpendicular to the borehole axis, penetrating casing walls, the cement layer and the formation rock, in order to create a hydraulic link between the borehole and the reservoir of hydrocarbons. In the oil industry, the “deep penetrating” type shaped charges are designed in order to provide optimal length of the perforation channel, while maintaining its adequate perforating diameter. Nowadays, the most commonly deep-penetrating shaped charges used, are the axially-symmetric shaped charges with conical liners made of copper powders. The charges create a cumulative jet reaching a velocity of approx. 7000 m/sec and are able to penetrate up to 1 m of rock matrix in favourable conditions. The article describes the parameters of shaped charges, that have been obtained as a result of numerical modelling. In order to finally confirm the target penetrating ability by the modelled shaped charges, one should check their real physical models in fire-ground conditions.

Abstract:

The present study was conducted to investigate the existence of any possible relationship between the cognitive reflection test (CRT), numeracy and academic majors. The statistical population of this study consisted of 117 freshmen studying under the faculties selected from the University of Tabriz. The generalised structural equation modelling technique was employed for data analysis. The research results indicated that CRT and numeracy had positive and significant effects on high school and university program selection. According to the research model and the higher CRT scores of engineering and medicine (two popular majors) than that of other majors, it appears that individuals with higher CRT and numeracy scores are more inclined to get accepted into these programs. Moreover, the relationship between CRT and numeracy was positive and significant, where CRT acted as the cause and numeracy as the effect. However, the reverse need not necessarily be true. Keywords: Cognitive reflection, numeracy skill, academic majors, relationship.
