Using Fuzzy Logic in the Research of the Data Visualization Process in Infographics

Data visualization in infographics is a rather interesting and yet little-studied process that requires comprehensive research. In the study, an analysis of the factors identified by an expert survey and divided by importance, which affect the visualization of data in infographics, is carried out. The analytic hierarchy process and the ranking method were used for the research. These methods show good calculation results when studying processes in which factors cannot be described using mathematical data. But, in the vast majority, the results obtained by these two methods give different results. Therefore, to verify the precision of the obtained results, the researchers recommend using the calculation of integral indicators of the quality of the considered process based on fuzzy logic. To calculate the integral quality indicators, it is required to establish a universal set of terms of values of isolated linguistic variables. As a result, this solution lies in the description of linguistic variables with the assignment of their designations, determination of recommended limits of values of universal fuzzy sets, and linguistic terms for the comparative process, construction, and calculation of functions belonging to linguistic variables.
Effect of personalization of instruction on students’ achievement and self-efficacy in mathematics word problems

This study investigated the effect of personalized print-based instruction on the achievement and self-efficacy regarding mathematics word problems of 320 senior secondary students in Nigeria. The moderator effect of gender was also examined on independent variable (personalization) and dependent variables (mathematics word problem achievement and self-efficacy). The t-test statistic was used to analyse the data collected for the study. The results showed that significant differences existed in the mathematics word problem achievement and self-efficacy beliefs of personalized and non-personalized groups, male and female personalized groups and male and female non-personalized groups.
1-1-2010 Employees , Firm Size and Profitability of U . S . Manufacturing Industries

We examine the relation between firm size and profitability w i hin 109 SIC four-digit manuf acturing industries. Depending on our measure of profitability, we find that profitability increases at decreasing rate and eventually declines in up to 47 of our industries. No r elation between profitability and size is found in up to 52 of our industries. These two categories account for 97 of our 109 industr ie . Profitability continues to increase as firms become larger in up to 11 industries. Hence, the relation between size and profitability is industry specific. But, regardless of the shape of the size profitability function, we find that profitab ility is negatively correlated with the number of employees for firms of a given size measured in terms of total assets and sales. These results are puzzling in the context of work by others who report that common stock returns are negatively correlated with size when size is meas ured by the market value of a company or w ith the work of those who argue that size is a proxy for risk. Interpreted against these works, our findings may mean that large firms earn excess returns, that small firms fail to earn their cost of capital, or that accounti ng returns simply behave diffe rently than market returns with respect to firm size.
A COMPARISON OF DIFFERENT SOLUTION METHODOLOGIES FOR MELTING AND SOLIDIFICATION PROBLEMS IN ENCLOSURES

Abstract A comparison of two frequently used computational techniques for solving phase-change problems is presented. The governing equations for the conservation of mass, momentum, and energy are solved using a control-volume-based discretization scheme. In Ike first approach, the physical space is mapped onto a simpler domain and the moving boundary is immobilized using Landau transformation. The computations are carried out on a uniform orthogonal grid in the transformed space using the stream function-vorticity formulation. The need to retain all the terms in the governing equations arising from the transformation, for an accurate simulation, is investigated. Simplifications in the governing equations have been used in the literature and are discussed. Both implicit and explicit methods are used to track the phase front. In the second approach, the computations are carried out on a uniform fixed grid in the physical space with primitive variables. The enthalpy-porosity formulation, with appropriate so.
Detection of abundant molecular gas in the UV-excess quasar Markarian 1014

Carbon dioxide (1 yields 0) emission has been detected from the UV-excess quasar Mrk 1014 (=PG 0157+001=IRAS 01572+0009) at z=0.163. Assuming the same empirical relationship between CO brightness and H2 surface mass density as has been found for giant molecular clouds in the Milky Way, the mass of H2 gas is approximately 4 x 10 to the 10th solar masses, i.e., more than ten times the H2 content of our Galaxy. The infrared and molecular gas properties of Mrk 1014 are similar to other warm, ultraluminous infrared galaxies such as Mrk 231, and IRAS 15206+3342 (z=0.125) from which CO(1 yields 0) emission is also reported. The trigger for the intense infrared activity in both Mrk 1014 and IRAS 15206+3342 appears to be a recent galaxy merger. It is suggested that objects such as these represent an important link in the evolution of ultraluminous infrared galaxies into UV-excess quasars.
Women Brazilian Jiu-jitsu practitioners showed a higher incidence of concussion: an epidemiological analysis

Knowledge about the prevalence of concussion in combat sports is important information to keep athletes’ and practitioners’ physical integrity in different modalities such as Brazilian jiu-jitsu (BJJ). Therefore, this study aimed to compare concussions incidence in BJJ between men and women practitioners. A randomized sample of 779 (689 men and 90 women) BJJ practitioners (age: 32.4 ± 9.8 years, training-time: 57.3 ± 54.4 months, training frequency: 3.4 ± 1.3 times/week). The injury analysis was done using a questionnaire with demographic data and a survey about concussions. The main results showed that women had a significantly higher frequency of concussions in training than men [38 (41%) women vs 147 men (20,5%); p ≤ 0.001]. Furthermore, women had a significantly higher frequency of loss of consciousness than men [13 (8.8%) men vs 4 (11%) women; p = 0.009], among the symptoms resulting from a concussion, headache, dizziness, and loss of balance, represented the most common symptoms in those affected by concussion, regardless of gender. The results of this study may be helpful to athletes, coaches, and federations to prevent this type of injury, mainly in women.
Somatic embryogenesis and plant regeneration from radicles of olive ( Olea europaea ‘Chemlal’) zygotic embryos

: Olive improvement by biotechnological tools such as genetic transformation requires an efficient in vitro regeneration system. Somatic embryogenesis seems the most suitable process. Our work describes for the first time the regeneration of whole plants in the main olive cultivar in Algeria ‘Chemlal’ via somatic embryogenesis induced from radicles of mature zygotic embryos. The obtained results showed that the establishment of a competent embryogenic culture is highly influenced by the chemical composition of the calli induction and maintenance media as well as addition of growth regulators. More than 10 and 13 % of nodular calli were obtained after callogenesis respectively on MS and OMc solid media containing IBA and zeatin followed by transfer to the same media without zeatin and a reduced concentration of auxin, while embryogenesis rates of 3.3 and 6.7 % were obtained respectively with IAA on MS medium and NAA on both tested media. However, no embryogenesis was observed with 2, 4-D or control which induced less callogenesis. Subsequently, an ECO medium with IBA, zeatin and BA particularly in liquid culture, allows better calli proliferation and embryogenic expression compared to OM and MS media. Finally, matured somatic embryos germi-nate quickly on a solid OM basal medium and generate normal well-developed plantlets easily acclimatized to natural conditions.
The Development of a Cyclone–Anticyclone Asymmetry within a Growing Baroclinic Wave

Abstract This study examines the cyclone–anticyclone asymmetry within idealized baroclinic waves. For this purpose a primitive equation (PE) model and a quasigeostrophic (QG) model are used. The Rossby number appears to be an essential external parameter for the cyclone–anticyclone asymmetry. Consequently, the Rossby number effect on nonlinear baroclinic waves is a central point of this study. First, the baroclinic stability of a vertically antisymmetric dipole jet flow is analyzed. Increasing the Rossby number in the PE model has the effect that the eddies of the fastest growing normal mode are tilted toward the northwest–southeast direction. The increase of this tilt is almost proportional to the Rossby number and arises due to leading-order corrections to the QG model. The nonlinear development of the fastest growing normal mode is simulated for various Rossby numbers. The PE model simulations exhibit the development of strong cyclones and weak anticyclones even when the cyclonic and anticyclonic shear.
A quadrupole system for measuring in situ the complex permittivity of materials: application to penetrators and landers for planetary exploration

A quadrupole system is proposed for measuring in situ the dielectric and resistive properties of grounds and seas, with possible applications not only to prospecting on Earth but also to planetary exploration with penetrators and landers. The theoretical approach is outlined for simple geometries, a few practical arrangements are proposed for specific planetary missions and the feasibility of the measurements is demonstrated in the laboratory.
Equity Vesting and Investment

This paper links the CEO’s concerns for the current stock price to reductions in real investment. We identify short-term concerns using the amount of stock and options scheduled to vest in a given quarter. Vesting equity is associated with a decline in the growth of research and development and capital expenditure, positive analyst forecast revisions, and positive earnings guidance, within the same quarter. More broadly, by introducing a measure of incentives that is determined by equity grants made several years prior, and thus unlikely driven by current investment opportunities, we provide evidence that CEO contracts affect real decisions.Received May 12, 2015; editorial decision December 15, 2016 by Editor Andrew Karolyi.
Color distributions in early type galaxies. III. Radial gradients in spectral features

Long-slit spectra covering the wavelength range 5000-9500 A have been obtained for three Virgo cluster ellipticals. Measurements of features in the spectra are presented, and their implications are discussed with particular reference to (1) anomalous r-i gradients; (2) ionized gas in the nucleus of NGC 4472; (3) nuclear emission line spectrum of M87; and (4) radial absorption line gradients in NGC 4472 with emphasis on the Na I 8190 A feature. 25 refs.
Quasilinear approximation for the spectrum of wind-generated water waves

According to Miles’ theory of wind-wave generation, water waves grow if the curvature of the wind profile at the critical height is negative. As a result, the wind profile changes in time owing to the transfer of energy to the waves. In the quasilinear approximation (where the interaction of the waves with one another is neglected) equations for the coupled air–water system are obtained by means of a multiple-time-scale analysis. In this way the validity of Miles’ calculations is extended, thereby allowing a study of the large-time behaviour. While the water waves grow owing to the energy transfer from the air flow, the waves in turn modify the flow in such a way that for large times the curvature of the velocity profile vanishes. The amplitude of the waves is then limited because the energy transfer is quenched. In the high-frequency range the asymptotic wave spectrum is given by a ‘–4’ law in the frequency domain rather than the ‘classical’ ‘–5’ law.
Analyzing the Driving Factors Causing Urban Expansion in the Peri-Urban Areas Using Logistic Regression: A Case Study of the Greater Cairo Region

The peri-urban area (PUA) of the Greater Cairo Region (GCR) in Egypt has witnessed a rapid urban expansion during the last few years. This urban expansion has led to the loss of wide, areas of agriculture lands and the annexation of many peripheral villages into the boundary of the GCR. This study analyzed the driving factors causing the urban expansion in the GCR during the period 2007–2017 using the logistic regression model (LRM). Eight independent variables were applied in this model: distance to the nearest urban center, distance to the nearest center of regional services, distance to water streams, distance to the main agglomeration, distance to industrial areas, distance to nearest road, number of urban cells within a 3 × 3 cell window and population density. The analysis was conducted using LOGISTICREG module in Terrset software. This research showed that the population density and distance to the nearest road have the highest regression coefficients, 0.540 and 0.114, respectively, and were the most significant driving factors of urban expansion during the last 10 years (2007–2017). Moreover, based on the results of the LRM, a probability map of urban expansion in the PUA was created, which shows that most urban expansion would be around the existing urban areas and near roads. The relative operating characteristic (ROC) value of 0.93 indicates that the probability map of urban expansion is valid.
Application of Combined Direct and Indirect Adaptive Control Algorithms for Temperature Control of Counter-Flow Heat Exchanger

Application of combined direct and indirect adaptive control (CDIAC) technique for temperature control of counter-flow heat exchanger (CFHE) which are used extensively in process industries have been dealt here. A modified CDIAC technique has been developed by carrying out improvement on the original proposed by Duarte and Narendra. The modified and original CDIAC algorithms and PID control algorithm have been tested on a CFHE designed and developed in the laboratory. It has been found that the modified technique has better disturbance rejection property compared to the other two techniques. The tracking of set-point change is also improved in the modified method. The claim of improvement is based on experimental investigations stretching over a period of six months.
Photonic band gap structures of obliquely incident electromagnetic wave propagation in a one-dimension absorptive plasma photonic crystal

The photonic band gap structures of obliquely incident electromagnetic waves propagating in a one-dimension plasma photonic crystal with collision have been studied on the basis of electromagnetic theory and transfer matrix approach. The dispersion relations for both the transverse electric wave case and the transverse magnetic wave case are deduced. And the photonic band gap structures, with their function dependence on the microplasma layer density, microplasma width, collision frequency, background material dielectric constant, and incident angle, are computed. The results show that there exist two photonic band gap structures in an adsorptive plasma photonic crystal: one is a normal photonic band gap structure and the other is an absorption photonic band gap structure. Parameter dependence of the effects is calculated and discussed.
Absolute frequency measurement of an I2 stabilized Nd:YAG optical frequency standard

The frequency of an I2 stabilized Nd:YAG optical frequency standard, developed at the BNM-INM as a national standard for the `mise en pratique' of the definition of the metre, has been measured with a frequency measurement chain based on a femtosecond laser. A frequency (in-)stability of 2.5×10-13τ-1/2 has been measured in the optical domain against a hydrogen maser. The measured (in-)stability decreases to 1×10-14 without evidence of flicker floor.
A note on Zariski dense orbit conjecture

In this paper we first note a result of birational automorphisms with bounded degree of projective varieties related with the Zariski dense orbit conjecture (ZDO) and the Zariski density of periodic points. Next, we give a reduced result of ZDO for automorphisms of projective threefolds, and showed ZDO for automorphisms of projective varieties $X$ with the irregularity $q(X)\ge\dim X-1$.
Blow-up of a structural acoustics model

This article studies the ﬁnite time blow-up of weak solutions to a structural acoustics model consisting of a semilinear wave equation deﬁned on a bounded domain Ω ⊂ R 3 which is strongly coupled with a Berger plate equation acting on the elastic wall, namely, a ﬂat portion of the boundary. The system is inﬂuenced by several competing forces, including boundary and interior source and damping terms. We stress that the power-type source term acting on the wave equation is allowed to have a supercritical exponent, in the sense that its associated Nemytskii operators is not locally Lipschitz from H 1 into L 2 . In this paper, we prove the blow-up results for weak solutions when the source terms are stronger than damping terms, by considering two scenarios of the initial data: (i) the initial total energy is negative; (ii) the initial total energy is positive but small, while the initial quadratic energy is suﬃciently large. The most signiﬁcant challenge in this work arises from the coupling of the wave and plate equations on the elastic wall.
The Ethics of Financial Speculation in Futures Markets

This article sketches an ethics of (financial) speculation in futures markets. (1) It identifies an intentionalistic fallacy prevalent in moral criticisms of speculation in general and of financial speculation in particular. (2) It scrutinizes the degree to which the recent debate on financial speculation with agricultural commodities follows the general pattern of moral criticism and its intentionalistic fallacy. (3) It then provides a theoretical and empirical in-depth analysis of long-only index funds' engagement in futures markets and concludes that moral criticisms which put them in the pillory as “hungermakers” are unjust(ified). This proves that ethics, understood as a theory of morality, can criticize moral criticisms of financial speculation on moral grounds. (4) Finally, this article discusses the option of interdisciplinary cooperation between ethics and economics.
Combining the unrestricted estimators into a single estimator and a simulation study on the unrestricted estimators

The purpose of this paper is to combine several regression estimators (ordinary least squares (OLS), ridge, contraction, principal components regression (PCR), Liu, r−k and r−d class estimators) into a single estimator. The conditions for the superiority of this new estimator over the PCR, the r−k class, the r−d class, βˆ(k, d), OLS, ridge, Liu and contraction estimators are derived by the scalar mean square error criterion and the estimators of the biasing parameters for this new estimator are examined. Also, a numerical example based on Hald data and a simulation study are used to illustrate the results.
Russia-Ukraine war: Modeling and Clustering the Sentiments Trends of Various Countries

With Twitter's growth and popularity, a huge number of views are shared by users on various topics, making this platform a valuable information source on various political, social, and economic issues. This paper investigates English tweets on the Russia-Ukraine war to analyze trends reflecting users' opinions and sentiments regarding the conflict. The tweets' positive and negative sentiments are analyzed using a BERT-based model, and the time series associated with the frequency of positive and negative tweets for various countries is calculated. Then, we propose a method based on the neighborhood average for modeling and clustering the time series of countries. The clustering results provide valuable insight into public opinion regarding this conflict. Among other things, we can mention the similar thoughts of users from the United States, Canada, the United Kingdom, and most Western European countries versus the shared views of Eastern European, Scandinavian, Asian, and South American nations toward the conflict.
Generalized conformal maps as classical symmetries of Yang-Mills fields

We show that a class of previously defined maps, called self-dual and causal morphisms, form classical symmetries of Yang-Mills fields in four complex dimensions. These maps generalize conformal transformations, and admit a nonlocal pullback connection that preserves the equations of the theory. First it is shown that self-dual morphisms form symmetries of the anti-self-dual Yang-Mills equations under this pullback. Then a supersymmetric generalization of causal morphisms is defined, which preserves solutions of the field equations for N=3 supersymmetric Yang-Mills theory. As a special case, this implies that a modified definition of causal morphisms form symmetries for the ordinary Yang-Mills field equations.
New Analytical Approach Based on Transfer Matrix Method (TMM) for Study of Tunable Plasmonic Modes in Graphene-Based Heterostructures

: This paper aims to study the reflection characteristics of optical beams in a hybrid graphene-hexagonal Boron Nitride (hBN)-graphene structure, which has been located on SiO 2 -Si layers. An analytical model is presented to derive the reflection characteristics by using the transfer matrix method. The upper Reststrahlen band has been chosen as the studied frequency range. It is shown that the characteristics of the reflected beam can be effectively controlled by varying the chemical potential of graphene sheets. The obtained results represent a high value of the reflected group delay ( 𝜏 𝑟 = 15.3 𝑝𝑠 ) at the frequency of 24.9 THz. The presented investigation will be helpful to control the group delays of reflected beams and can be utilized for the design of innovative graphene-hBN devices in the mid-infrared wavelengths.
FlatENN: Train Flat for Enhanced Fault Tolerance of Quantized Deep Neural Networks

Model compression via quantization and sparsity enhancement has gained an immense interest to enable the deployment of deep neural networks (DNNs) in resource-constrained edge environments. Although these techniques have shown promising results in reducing the energy, latency and memory requirements of the DNNs, their performance in non-ideal real-world settings (such as in the presence of hardware faults) is yet to be completely understood. In this paper, we investigate the impact of bit-flip and stuck-at faults on activation-sparse quantized DNNs (QDNNs). We show that a high level of activation sparsity comes at the cost of larger vulnerability to faults. For instance, activation-sparse QDNNs exhibit up to 17.32% lower accuracy than the standard QDNNs. We also establish that one of the major cause of the degraded accuracy is sharper minima in the loss landscape for activation-sparse QDNNs, which makes them more sensitive to perturbations in the weight values due to faults. Based on this observation, we propose the mitigation of the impact of faults by employing a sharpness-aware quantization (SAQ) training scheme. The activation-sparse and standard QDNNs trained with SAQ have up to 36.71% and 24.76% higher inference accuracy, respectively compared to their conventionally trained equivalents. Moreover, we show that SAQ-trained activation-sparse QDNNs show better accuracy in faulty settings than standard QDNNs trained conventionally. Thus the proposed technique can be instrumental in achieving sparsity-related energy/latency benefits without compromising on fault tolerance.
