Abstract:

IEEE floating-point arithmetic standards 754 and 854 reflect the present state of the art in designing and implementing floating-point arithmetic units. A formalism applied to a standard non-trapping mode floating-point system shows incorrectness of some numeric and non-numeric results. A software emulation of decimal floating-point computer arithmetic supporting an enhanced set of exception symbols is reported. Some implementation details, discussion of some open questions about utility and consistency of the implemented arithmetic with the IEEE Standards are provided. The potential benefit for computations with infinite symbolic elements is outlined.

Abstract:

Numeric regional models are necessary to reconstruct the nature and conditions of formation of i geological structures, to obtain ideas about the evolution of different zones of the crust and upper mantle, the evolution of fold and fault dislocations and predicting expression of manifestation of deep structures on earth’s surface. Numeric reconstructions are based on computational dynamics methods, in which rock is represented as highly viscous liquid. «Markers-in-cell» method is one of the implementations of that approach. We propose to accelerate model ported into Python, as compared to Matlab, without rejecting sequential enumeration of markers. It is shown that the solutions can be either code vectorization (refactoring with binary indices instead of enumeration loops and numpy functions) or acceleration of loops by their pre-compilation or parallel computations. The results obtained can be used in the implementation of numeric geological modeling in Python.

Abstract:

This paper deals with an implementation method of component-based Petri nets system based on a graphical programming language (LabVIEW). LabVIEW is not only a graphical programming language, but also a virtual instrument platform which is widely used in virtual measurement and control system. The Places (token number) of Petri nets are represented by Numeric Controls of LabVIEW. The Transitions of Petri nets are represented by subVIs of LabVIEW. Transition subVI will change the tokens of Places by the Numeric Controls' Reference when it is fired. This method will make it ease to implement a Petri net by simply combining Place and Transition components (subVI). The example implementing a special Petri net shows that the Front Panel of the controller reflects the system operating state directly; the Block Diagram is similar to the topology of original Petri net. The combination of two graphic languages makes the modeling, analysis and formal verification of measurement and control system based on Petri nets easier.

Abstract:

Purpose: The article presents both numeric implementation in Japan and the Arabic gematrical calculation (hisababajadun) in Indonesia. It is common for the people in Japan and Indonesia to believe in the power of numerals and to assume whether or not certain digits induce bad luck. Methodology: The research applies a qualitative descriptive method through a contrastive approach. Main Findings: Data analysis is based on both Koizumi's approach (1995) to the meaning of numbers in the Japanese language and Al Bani's view on hisababajadun. Our study shows that the numeric calculation in Japan uses luckiness as its ground while the hisababajadun builds its mechanism on birth date calculation according to Quranic Neuro-Hypnosis. Implications/ Applications: The research may enrich existing theoretical references on the belief toward numbers in both Japan and Indonesia. While in practice, it may as well be a reference for the application of numeric calculation methods in both cultures. Novelty/Originality of this study: This study is unique and novel as it enhances the understanding of the importance of numerals in two distinct cultures i.e., Japan and Indonesia. Moreover, this study sheds light on some crucial aspects of numeral calculation including how these numerals are used, what beliefs are attached to them and how and where these numerals are used for solving life problems.

Abstract:

In the process of learning a song work, constraints often occur in students' limited memory. The song material given at the first meeting will be forgotten when reviewed at the second meeting, to overcome this we try to apply number notation as a way for students to recall the tone of the song that has been given. The purpose of this study was to determine the efficiency and response of the application of number notation to song learning in junior high school. This study uses a qualitative descriptive method, the data collection technique used in this study is to provide a pre-test and post-test which contains 10 questions regarding numerical notation. The findings of this study gave a positive response to the students, in the initial pre-test found results that were not good because many of the students did not understand numeric notation at all, but after that they were shown a video of reading material notation of numbers and then a post-test was carried out, the results were good. The students made progress after seeing the video. The conclusion of this study is to implement numeric notation in the song learning process, making it easier for students to memorize the material and making it easier for teachers in the process of conveying it, thus it is hoped that it can be a solution to the problems previously mentioned.

Abstract:

<p>We propose a hardware implementation on a field-programmable gate array (FPGA) of the cerebellar model articulation controller (CMAC) with an integer numeric system. Existing hardware implementations of floating-point processes on FPGAs have utilized the IEEE 754 standard, which introduces complex operations leading to long processing times. For the most complex part of the CMAC, that is, the exponential operator, traditional look-up table methods carry high memory costs. We, therefore, use a Taylor series to realize the exponential operator. Finally, we connect all the modules into the CMAC.</p> <p>&nbsp;</p>

Abstract:

Abstract Objectives The objective of this study was to examine the impact of numeric versus interpretive calorie labelling on consumer noticing, use, and perceptions of labels. We hypothesized that due to their at-a-glance format, interpretive labels would outperform numeric labels. Methods Using a pre-post quasi-experimental controlled trial design, three campus cafeterias were randomized to receive numeric calorie labelling, traffic light labelling (i.e., red, amber, or green symbol indicating the number of calories), or no labelling for two weeks. Exit surveys were conducted with cafeteria patrons prior to (n = 949) and following (n = 1110) implementation of labels. Surveys queried sociodemographic characteristics, the details of the most recent cafeteria purchase, and noticing, use, and perceptions of labels. Chi-squared tests and multinomial logistic regression were used to determine the impact of format on label noticing, use, and perceptions. Results Label noticing increased from 23% to 43% among those exposed to numeric labels and 28% to 63% among those exposed to traffic light labels, compared to no change in the control (15%) (P &lt; 0.05). Among those who noticed labels, a higher proportion (66%) of those in the traffic light condition reported using the labels to inform their purchase compared to the numeric (50%) and control (50%) conditions (P &lt; 0.05). Scores for perceived ease of use and understanding of the labels were high at both labelling sites. Compared to the pre-test period, there was a slight increase (6%) in the proportion of people who indicated traffic light labels were easy to use and understand versus no change in perceptions at the numeric and control sites (P &gt; 0.05). Conclusions Cafeteria patrons exposed to calorie labels reported noticing and using them, with higher salience for traffic light labels. The implementation of such interpretive labels at the point-of-purchase may provide cues to enable consumers to make informed choices, consistent with front-of-pack labels on packaged foods under consideration in many jurisdictions.

Full text

Abstract:

Wave-equation migration velocity analysis (MVA) is a technique similar to wave-equation tomography because it is designed to update velocity models using information derived from full seismic wavefields. On the other hand, wave-equation MVA is similar to conventional, traveltime-based MVA because it derives the information used for model updates from properties of migrated images, e.g., focusing and moveout. The main motivation for using wave-equation MVA is derived from its consistency with the corresponding wave-equation migration, which makes this technique robust and capable of handling multipathing characterizing media with large and sharp velocity contrasts. The wave-equation MVA operators are constructed using linearizations of conventional wavefield extrapolation operators, assuming small perturbations relative to the background velocity model. Similar to typical wavefield extrapolation operators, the wave-equation MVA operators can be implemented in the mixed space-wavenumber domain using approximations of differentorders of accuracy. As for wave-equation migration, wave-equation MVA can be formulated in different imaging frameworks, depending on the type of data used and image optimization criteria. Examples of imaging frameworks correspond to zero-offset migration (designed for imaging based on focusing properties of the image), survey-sinking migration (designed for imaging based on moveout analysis using narrow-azimuth data), and shot-record migration (also designed for imaging based on moveout analysis, but using wide-azimuth data). The wave-equation MVA operators formulated for the various imaging frameworks are similar because they share elements derived from linearizations of the single square-root equation. Such operators represent the core of iterative velocity estimation based on diffraction focusing or semblance analysis, and their applicability in practice requires efficient and accurate implementation. This tutorial concentrates strictly on the numeric implementation of those operators and not on their use for iterative migration velocity analysis.

Abstract:

Secret keys connecting users to the system is the heart of cryptographic systems. With the recent wars, several cryptographic systems that use alpha-numeric passwords have been known to be vulnerable to many attacks. Image based password systems were introduced to add more complexity and security. This paper employs human uniqueness of narrative skills on an image-based password system with focus on theme in the password generation process. To generate the secret password, a specially designed computer game was used. We used narrative constructs composed of cartoon image sequences to generate user-speciﬁc secret key. The durability of generated passwords and the authentication process while assessing the reconstruction process by a potential hacker was verified. Under imposed psychological duress, users failed retrieving the password sequence suggesting the reliability as an anti-coercive attack cybersecurity tool. A set of experiments were used to analyze user behavior behind the image-based password system. EEG measurements demonstrated increased activity of α rhythms in F3 and FC5 channel bins and augmented levels of β rhythms in F3 and O1 channels, suggesting users added personalization to authentication more than in alpha-numeric password-based logins.

Abstract:

This paper presents a framework for the implementation of a decision support system that considers spatial, temporal and managerial factors in assessing the potential impact of crop amendments on the cost of a given production scenario. The proposed system includes a database and a numeric simulation model. The database is linked to previously recorded crop responses for a given agricultural input under different conditions while the numeric simulation model determines the probability of different levels of profit for each decision option. This system then determines the optimal uniform rate of application of an amendment to maximize profits, or to define the range of such rates for a case of variable rate application. Uncertainty-based treatment of each model input allows for a balance between the potential results of under-application or over-application.

Abstract:

This paper introduces the design and realization of multiple blocks ciphering techniques on the FPGA (Field Programmable Gate Arrays). A back propagation neural networks have been built for substitution, permutation and XOR blocks ciphering using Neural Network Toolbox in MATLAB program. They are trained to encrypt the data, after obtaining the suitable weights, biases, activation function and layout. Afterward, they are described using VHDL and implemented using Xilinx Spartan-3E FPGA using two approaches: serial and parallel versions. The simulation results obtained with Xilinx ISE 9.2i software. The numerical precision is chosen carefully when implementing the Neural Network on FPGA. Obtained results from the hardware designs show accurate numeric values to cipher the data. As expected, the synthesis results indicate that the serial version requires less area resources than the parallel version. As, the data throughput in parallel version is higher than the serial version in rang between (1.13-1.5) times. Also, a slight difference can be observed in the maximum frequency.

Abstract:

Over the past three decades, Kazakhstan put a lot of efforts and resources into implementation of the Social Health Insurance. Debates on health policy often focuses on contribution rates in SHI that should limit the growth of out-of-pocket spending. We investigate a central issue to the debates: are the contribution rates stipulated by the law sufficient to minimize the out-of-pocket health payments? We develop a simple dynamic stochastic general equilibrium (DSGE) model based on over-lapping generations macroeconomic model (OLG) to describe the process of healthcare reforms in Kazakhstan. The numeric results argue that current contribution rates will not be enough to reduce the share of ou-of-pocket health payments in the economy. On contrary, optimal inter-temporary consumption-saving decision of households may bring us to the optimal composition of total spending that shifts toward health, and the out-of-pocket health expenditures can easily exceed current level of 40 percent.

Full text

Abstract:

The problem of the creation of numerical constants has haunted the Genetic Programming (GP) community for a long time and is still considered one of the principal open research issues. Many problems tackled by GP include finding mathematical formulas, which often contain numerical constants. It is, however, a great challenge for GP to create highly accurate constants as their values are normally continuous, while GP is intrinsically suited for combinatorial optimization. The prevailing attempts to resolve this issue either employ separate real-valued local optimizers or special numeric mutations. While the former yield better accuracy than the latter, they add to implementation complexity and significantly increase computational cost. In this paper, we propose a special numeric crossover operator for use with Robust Gene Expression Programming (RGEP). RGEP is a type of genotype/phenotype evolutionary algorithm closely related to GP, but employing linear chromosomes. Using normalized least squares error as a fitness measure, we show that the proposed operator is significantly better in finding highly accurate solutions than the existing numeric mutation operators on several symbolic regression problems. Another two important advantages of the proposed operator are that it is extremely simple to implement, and it comes at no additional computational cost. The latter is true because the operator is integrated into an existing crossover operator and does not call for an additional cost function evaluation.

Full text

Abstract:

We consider the fundamental problem of injectively mapping a surface mesh with disk topology onto a boundary constrained convex domain. We start from the basic observation that mapping a strip of triangles onto a rectangular shape always yields a valid embedding, if the vertices that bound the strip are sorted coherently along the sides of the rectangle. Based on this intuition, we propose a straightforward algorithm, called Stripe Embedding, that operates by decomposing the input mesh into a set of triangle strips and then embeds each strip into the target domain by means of linear interpolation between two previously embedded vertices. Thanks to its simplicity, Stripe Embedding is extremely efficient and permits to switch to an exact implementation without almost increasing its running times. Stripe Embedding is up to three orders of magnitude faster than the Tutte embedding for same numerical model and, even when implemented with costly rational numbers, it is faster than any floating point implementation of prior methods at any scale.

We present a hybrid analytic-numeric method to calculate the transmission and reflection of light that is fluxed into a bounded complicated optical structure surrounded by air. The solution is obtained by numerical calculations inside a square containing the structure and by analytical calculations outside the square. For solving the 2D Helmholtz equation we formulate transparent-influx boundary conditions (TIBCs) on the boundaries of the square; these are incorporated into a variational formulation of the Helmholtz equation to obtain a FEM-implementation for the interior calculations.

Abstract:

This paper presents an original package for investigating numerical solutions of ordinary differential equations, which is built in the Sage computer algebra system. This project is focused on a closer integration of numerical and symbolic methods while primarily aiming to create a convenient tool for working with numerical solutions in Sage. The package defines two new classes: initial problems and approximate solutions. The first class defines tools for symbolic computations related to initial problems, while the second class defines tools for interpolating values of symbolic expressions on an approximate solution and estimating the error with the use of the Richardson method. An implementation of the Runge–Kutta method is briefly described, with its main feature being the possibility of working with arbitrary Butcher tableaux and arbitrary numeric fields.

Abstract:

Large-scale inverse problems that require high-performance computing arise in various fields, including regional air quality studies. The paper focuses on parallel solutions of an emission source identification problem for a 2D advection–diffusion–reaction model where the sources are identified by heterogeneous measurement data. In the inverse modeling approach we use, a source identification problem is transformed to a quasi-linear operator equation with a sensitivity operator, which allows working in a unified way with heterogeneous measurement data and provides natural parallelization of numeric algorithms by concurrent calculation of the rows of a sensitivity operator matrix. The parallel version of the algorithm implemented with a message passing interface (MPI) has shown a 40× speedup on four Intel Xeon Gold 6248R nodes in an inverse modeling scenario for the Lake Baikal region.

Full text

Abstract:

A computer program (MetaCon) is described for the evaluation of flux control, concentration control and branch-point distribution control coefficients of a metabolic pathway. Requiring only the reaction scheme as input, the program produces algebraic expressions for the control coefficients in terms of elasticity coefficients, metabolite concentrations and pathway fluxes. Any of these variables can be substituted by numeric or simple algebraic expressions; the expressions will then be automatically rearranged in terms of the remaining unknown variables. When all variables have been substituted, numeric values will be obtained for the control coefficients. The program is a computerized implementation of the matrix method for the determination of control coefficients. The features of MetaCon are compared with those of other programs available to workers in Metabolic Control Analysis. Potential benefits of, and methods of using, MetaCon are discussed. The mathematical background and validity of the matrix method rules are discussed, and the algorithm used by MetaCon is described. The matrix method is shown to be a specific case of a previously described general formalism for calculating control coefficients.

Abstract:

Users of embedded languages might want to pattern match on embedded programs. Making this possible requires a considerable effort from the developer of the language, because the underlying data types are usually hidden. This paper first analyses the available solutions for this problem. As pattern synonyms [13] and function patterns [6] seem promising, a compromise between these two is proposed: restricted function patterns. These are more general than pattern synonyms, but it is still possible to process them at compilation time. It is interesting that this proposal makes Haskell's rules about matching numeric literals more regular. It also provides Erlang's list prefix patterns in a consistent way instead of ad hoc implementations. Finally, a lightweight prototype implementation is presented, which implements the functionality of the proposal, but cannot give the static guarantees that proper compiler support could achieve.

Full text

Abstract:

The surface of equal two-way time referred to as the isochron is a fundamental concept in seismic imaging. The shape of an isochron depends on the source and receiver locations, on the wave type, and on the parameters constituting the seismic velocity model. A perturbation of a parameter of the velocity model forces the isochron points to move along trajectories called velocity rays, with the selected model parameter as the variable along the rays. Based on earlier work describing first-order approximations to velocity rays, I develop a general theory for velocity rays valid for 3D heterogeneous and anisotropic velocity models. By this theory, velocity rays can be obtained in a way similar to the way conventional rays are computed by numeric integration of a system of ordinary differential equations (ODEs). The process is organized with ODE solvers on two levels, where the upper level is model independent. The lower level includes conventional one-way kinematic and dynamic tracing of source and receiver rays, as well as calculation of ray perturbation quantities. Accurate velocity rays are expected to be useful for perturbation of reflectors mapped from the time domain to the depth domain, for remigration of seismic images in the depth domain, and for velocity model updating.

Full text

Abstract:

The reciprocal relationships between ecological process and landscape pattern are fundamental to landscape ecology. Landscape ecologists traditionally use raster maps portraying classified features such as land use or land cover categories, and metrics suggested by the patch-corridor-matrix conceptual model of pattern. Less attention has been given to the landscape gradient conceptual model and raster maps portraying numeric features such as greenness or percent vegetation cover. We introduce the open-source tool GraySpatCon to calculate and map a variety of landscape pattern metrics from both conceptual models using either categorical or numeric maps. The 51 metrics, drawn mostly from the landscape ecology and image processing literatures, are calculated from the frequencies of input pixel values and/or the pixel value adjacencies in an analysis region. GraySpatCon conducts either a moving window analysis which produces a continuous map of a pattern metric, or a global analysis which produces a single metric value. We describe an implementation in the GuidosToolbox desktop application which allows novice users to interactively explore GraySpatCon functionality. In the R desktop environment, we demonstrate several metrics using an example map of percent tree cover and illustrate a multi-scale moving window analysis to identify scale domains. Comparisons of computational efficiency indicate a substantial GraySpatCon advantage over related software in the R environment.

Abstract:

Background Many barriers prevent those with spinal cord injury or disease (SCI/D) from adhering to recommended exercise guidelines, thus increasing risks of secondary health conditions. Mainstream technology options, such as virtual reality (VR), have the potential to facilitate needed exercise participation. However, further research on VR exercise modalities is needed to determine feasibility, effectiveness and to ultimately guide practice recommendations. Objectives The goal of this pilot feasibility study was to determine whether VR exergaming is non-inferior to the current standard of care (SoC) upper extremity aerobic exercise for individuals with SCI/D. Methods/Overview 25 participants with SCI/D completed 10-minute exercise sessions with either VR or the SoC, and after a rest break, then completed 10 minutes of exercise with the other modality. Primary outcomes of heart rate (HR) and rate of perceived exertion (RPE) were collected at baseline, 5 minutes into exercise, and at 10 min (end of the exercise session) for each modality. Secondary exploratory measures included a Numeric Pain Rating Scale measured pre- and post- each exercise session, and a post-study likeability survey. Results There were no significant differences in HR or RPE between virtual reality exergaming and the standard of care, and 100% of participants preferred the VR over SoC for the exercise. Conclusions VR exergaming was non-inferior to the SoC for short duration upper extremity exercise in those with SCI/D. Implementing VR for patients with SCI/D should be studied further to observe the longer term effect on cardiovascular health and to determine feasibility and compliance for home use.

Abstract:

This paper proposes an electrical active power optimization for self-excited induction generator-wind turbine system (SEIG-WTS) using a perturb and observe (PO)-based maximum power point tracking. The main advantage is the optimization of the SEIG active power of SEIG-WTS and the simply practical implementation with rotor speed sensor, current sensor and three phase inverter. The active power optimization of SEIG-WTS is achieved by perturbing angular magnetic field speed with stator reference voltage. To test the effectiveness of the proposal, numeric simulations were carried out under very challenging conditions with wind speed profile in steps and actual wind speed profile. The proposal reaches the maximum power in 7 seconds for hardest condition when the system works at high rotor speed. The proposal is useful for the development of maximum power point tracking control (MPPT) controllers due to its simplicity in implementation.This paper proposes an electrical active power optimization for self-excited induction generator-wind turbine system (SEIG-WTS) using a perturb and observe (PO)-based maximum power point tracking.
