To comply with STEP-NC (ISO 14649), a new paradigm for NC programming, many computer systems involved in NC manufacture are required to reshape in both functionality and structure. This paper reports a feature-based NC programming system for prismatic parts to be machined using STEP-NC machine tools. The proposed system consists of three functional modules, i.e. a feature-based modeler, a process planner and a part program generator. The modeler provides a graphical environment for the part model, which is created by adding manufacturing features on a 2.5 D sweep primitive shape. The process planner determines which operations are to be performed for the features, generates workingsteps and then produces a reasonable workplan. Finally both the geometrical and the process information are passed to the part program generator to form a complete ISO 14649-compliant file. The proposed system is demonstrated through the generation of the STEP-NC part program for an example part, and major issues such as the feature-operation mapping and the workingstep sequencing etc are also addressed in this paper.

Fibrinogen is a large heterogeneous aggregation/degradation-prone protein playing a central role in blood coagulation and associated pathologies, whose structure is not completely resolved. When a high-molecular-weight fraction was analyzed by size-exclusion high-performance liquid chromatography/small-angle X-ray scattering (HPLC-SAXS), several composite peaks were apparent and because of the stickiness of fibrinogen the analysis was complicated by severe capillary fouling. Novel SAS analysis tools developed as a part of theUltraScan Solution Modeler(US-SOMO; http://somo.uthscsa.edu/), an open-source suite of utilities with advanced graphical user interfaces whose initial goal was the hydrodynamic modeling of biomacromolecules, were implemented and applied to this problem. They include the correction of baseline drift due to the accumulation of material on the SAXS capillary walls, and the Gaussian decomposition of non-baseline-resolved HPLC-SAXS elution peaks. It was thus possible to resolve at least two species co-eluting under the fibrinogen main monomer peak, probably resulting from in-column degradation, and two others under an oligomers peak. The overall and cross-sectional radii of gyration, molecular mass and mass/length ratio of all species were determined using the manual or semi-automated procedures available within theUS-SOMOSAS module. Differences between monomeric species and linear and sideways oligomers were thus identified and rationalized. This newUS-SOMOversion additionally contains several computational and graphical tools, implementing functionalities such as the mapping of residues contributing to particular regions ofP(r), and an advanced module for the comparison of primaryI(q)versus qdata with model curves computed from atomic level structures or bead models. It should be of great help in multi-resolution studies involving hydrodynamics, solution scattering and crystallographic/NMR data.

As scientists from various domains increasingly resort to agent-based simulation for a more thorough understanding of real-world phenomena, the need for a simulation environment that facilitates rapid development of multi-agent systems is growing. Such a platform should provide means of visualizing the simulated scenario. In this paper we present the agent visualization system, the first system of its kind to specifically focus on catering to the visualization needs of agent-based simulation. The proposed system is a generic add-on that equips a simulation environment with a rich set of visualization facilities offering a variety of textual and graphical browsers that allow the modeler to detect trends and relationships in the simulation scenario. Some techniques from the field of information visualization were adapted and added to the system, while others were devised especially to be used in it. Regardless of their origin, all visualization techniques were thoroughly revised to make them generic enough to fit in our generic system. Agent visualization is more challenging than traditional information visualization in more than one respect. One of them is that the data to be visualized is not static; the simulation system is constantly producing data with every time step. Moreover, the sheer amount of data, together with its diversity, call for special adaptations to ensure that the system remains responsive and generic. To illustrate the various features of the proposed agent visualization system, we present a visualization of MicroTerra; a simulation scenario involving a group of beings trying to maximize their food intake.

Model-Based Development has become an industry wide standard paradigm. As an open source alternative, Scilab/Xcos is being widely employed as a hybrid dynamic systems modeling tool. With the increasing efficiency in implementation using graphical model development and code generation, the modeling and simulation community is struggling with assuring quality as well as maintainability and extendibility. Refactoring is defined as an evolutionary modernization activity where, most of the time, the structure of the artifact is changed to alter its quality characteristics, while keeping its behavior unchanged. It has been widely established as a technique for textual programming languages to improve the code structure and quality. While refactoring is also regarded as one of the key practices of model engineering, the methodologies and approaches for model refactoring are still under development. Architecture-Driven Modernization (ADM) has been introduced by the software engineering community as a model-based approach to software modernization, in which the implicit information that lies in software artifacts is extracted to models and model transformations are applied for modernization tasks. Regarding refactoring as a low level modernization task, the practices from ADM are adaptable. Accordingly, this paper proposes a model-based approach for model refactoring in order to come up with more efficient and effective model refactoring methodology that is accessible and extendable by modelers. Like other graphical modeling tools, Scilab/Xcos also possesses a formalized model specification conforming to its implicit metamodel. Rather than proposing another metamodel for knowledge extraction, this pragmatic approach proposes to conduct in place model-to-model transformations for refactoring employing the Scilab/Xcos model specification. To construct a structured model-based approach, the implicit Scilab/Xcos metamodel is explicitly presented utilizing ECORE as a meta-metamodel. Then a practical model transformation approach is established based on Scilab scripting. A Scilab toolset is provided to the modeler for in-place model-to-model transformations. Using a sample case study, it is demonstrated that proposed model transformation functions in Scilab provide a valuable refactoring tool.

This manuscript is devoted to investigating a fractional-order mathematical model of COVID-19. The corresponding derivative is taken in Caputo sense with power-law of fractional order μ and fractal dimension χ. We give some detailed analysis on the existence and uniqueness of the solution to the proposed problem. Furthermore, some results regarding basic reproduction number and stability are given. For the proposed theoretical analysis, we use fixed point theory while for numerical analysis fractional Adams–Bashforth iterative techniques are utilized. Using our numerical scheme is verified by using some real values of the parameters to plot the approximate solution to the considered model. Graphical presentations corresponding to different values of fractional order and fractal dimensions are given. Moreover, we provide some information regarding the real data of Saudi Arabia from 1 March 2020 till 22 April 2021, then calculated the fatality rates by utilizing the SPSS, Eviews and Expert Modeler procedure.

The bond graph modeling method was discovered by Henry Painter in 1959 and has quickly become a wide spread method all over the modeling engineering world. The method is based on the analysis of power circulation in systems and has some indisputable advantages over other modeling methods, based in principle on mathematical aspects. The paper proposes a comparison between the bond graph method and Lagrange's equations method, by applying both methods to model a mechanical system. The bond graph model is a graphical model. There are three possibilities to exploit the bond-graph diagram. The first one consists in deducing a system of differential or algebraic-differential equations from the diagram. The second one consists in obtaining the block diagram model from the bond graph diagram, without additionally writing any equations, followed by the block diagram implementation in the appropriate software, which permits to perform simulations at once. The third one consists in implementing the bond graph diagram directly in the appropriate software, where simulations can immediately run. The advantages and the disadvantages of the methods are emphasized, but the decision about the most appropriate method is up to the modeler.

Automated model generation and solution for motion planning and re-planning of robotic systems will play an important role in the future reconfigurable manufacturing systems. Solving the inverse kinematic problem has always been the key issue for computer-controlled robots. Considering the large amount of similarities that exist among the industrial 6R robotic systems, this work classifies them into two main types (Puma-type and Fanuc-type) and then provides a unified geometric solution based on a unified kinematic structure called Generic Puma-Fanuc (GPF) model. A widespread study of different kinematic groups originating from eleven robot manufacturers made it possible to develop the GPF model that can be reconfigured according to the D-H rules (Denavit, and Hartenberg1). A graphical interface by which the robot kinematic model is represented and the D-H parameters are auto-generated for use in solving the inverse kinematic problem. A generic solution module called Unified Kinematic Modeler and Solver (UKMS) implements the geometric approach for solving the inverse kinematic problem. The outcomes are then employed for robot control. Numerical examples are presented for exploring the solution capabilities of our unified approach.

This paper presents the validation of the End Point Rate (EPR) tool for QGIS (EPR4Q), a tool built-in QGIS graphical modeler for calculating the shoreline change with the end point rate method. The EPR4Q tries to fill the gaps in user-friendly and free open-source tools for shoreline analysis in a geographic information system environment since the most used software—Digital Shoreline Analysis System (DSAS)—although being a free extension, it is created for commercial software. Additionally, the best free, open-source option to calculate EPR is called Analyzing Moving Boundaries Using R (AMBUR); since it is a robust and powerful tool, the complexity can restrict the accessibility and simple usage. The validation methodology consists of applying the EPR4Q, DSAS, and AMBUR with different types of shorelines found in nature, extracted from the US Geological Survey Open-File. The obtained results of each tool were compared with Pearson’s correlation coefficient. The validation results indicate that the EPR4Q tool acquired high correlation values with DSAS and AMBUR, reaching a coefficient of 0.98 to 1.00 on linear, extensive, and non-extensive shorelines, proving that the EPR4Q tool is ready to be freely used by the academic, scientific, engineering, and coastal managers communities worldwide.

Human activity combined with the dynamics of severe climate conditions are accepted the main drivers of wildfire events in the Mediterranean region. This fact is urging for further comprehensive research focusing on the wildland-urban interface (WUI) at metropolitan scale, at which the tension between the cause and effect of wildfire is the highest. In this context, the study brings a comparative case between two metropolitan areas from Western Balkan countries, the forest lands of which are classified by their index of wildfire ignition probability (WIPI) and wildfire spreading capacity (WSCI). Originally, both indexing methods rely on a multi-criteria evaluation which considers simultaneously the geophysical, hydrometeorological and anthropogenic factors of the territory. All stages of the process are performed by utilizing QGIS software. First, the forest surfaces within the metropolitan zone of Tirana (AL) and Sarajevo (BH) are extracted from Urban Atlas land cover data being provided as an open source by Copernicus data portal (EU). Reference points grid (distance of 100m) overlapping with the forest surfaces serve as pivot points to which the relative values of each criteria are projected. Later the absolute values are normalized into 10 classes via Jenks natural break method. The class value of each criterion is introduced into the indexing equation multiplied by the unique impact factor being weighted via pairwise comparative method in Analytical Hierarchy processing. The majority of the workflow steps are automated via Graphical Modeler in QGIS utilizing open source spatial data, giving floor to further applicability of the method to similar cases. As a result, there are produced statistical and graphical information being useful for identifying wildfire prone forest surfaces within the metropolitan areas. Being applied into two different study areas, the results enable a comparative discussion and evaluation at regional scale. By utilizing open source software and data, this work contributes in the development of practical and re-applicable models of wildfire risk assessment promoting open access scientific culture. Finally, the study results successful in testing a rapid and cost free method for identifying the forest areas prone to wildfire ignition and spreading risk in metropolitan areas in support to disaster risk reduction agendas and sustainable Development Goals.

Abstract. Modelling and classification difficulties are fundamental issues in natural hazard assessment. A geographic information system (GIS) is a domain that requires users to use various tools to perform different types of spatial modelling. Bivariate statistical analysis (BSA) assists in hazard modelling. To perform this analysis, several calculations are required and the user has to transfer data from one format to another. Most researchers perform these calculations manually by using Microsoft Excel or other programs. This process is time-consuming and carries a degree of uncertainty. The lack of proper tools to implement BSA in a GIS environment prompted this study. In this paper, a user-friendly tool, bivariate statistical modeler (BSM), for BSA technique is proposed. Three popular BSA techniques, such as frequency ratio, weight-of-evidence (WoE), and evidential belief function (EBF) models, are applied in the newly proposed ArcMAP tool. This tool is programmed in Python and created by a simple graphical user interface (GUI), which facilitates the improvement of model performance. The proposed tool implements BSA automatically, thus allowing numerous variables to be examined. To validate the capability and accuracy of this program, a pilot test area in Malaysia is selected and all three models are tested by using the proposed program. Area under curve (AUC) is used to measure the success rate and prediction rate. Results demonstrate that the proposed program executes BSA with reasonable accuracy. The proposed BSA tool can be used in numerous applications, such as natural hazard, mineral potential, hydrological, and other engineering and environmental applications.

In this paper, a new methodology is proposed to determinate the controllability and the observability matrices of linear time varying systems modeled by bond graph. As the bond graph model can be viewed as a state space representation and as a module (algebraic approach), the determination of controllability and observability matrices is presented with the graphical approach. The equivalence between the two approaches (Graphic, Mathematical) is proposed and a graphical methodology is pointed out directly on the bond graph representation.

The article considers the method of using information technology tools for the construction and analysis of graphs in the process of studying the course of general physics. Among the significant number of computer tools for plotting functions, special attention is paid to software that allows to process laboratory tasks results in physics effectively and graphically, to perform calculations and build on their basis graphs of dependencies while solving tasks, to demonstrate models of physical phenomena on lectures. Using the example of laboratory work on the capacitance of the capacitor determination, it is shown that as a result of using the software Graph for processing experimental data reduces the time of their processing and the error of the calculation results. The construction of function graphs of the studied quantities also contributes to a fuller understanding of the physical process, which is considered in the task. The method of using the graphical capabilities of the Excel spreadsheet and plotting functions based on the analytical solution of the problem are considered. The construction of dependency graphs of physical quantities in real time is considered exemplified by oscillations of a mathematical pendulum, which are modeled using SimPHY software. Real-time graphs can be built by processing physical sensor data of various types using the Arduino hardware computing platform and SFMonitor software. Carrying out laboratory work in this way makes it possible to conduct a real physical experiment simultaneously with the display of its results on the screen, to observe the relationship between specific changes made to the conditions of the experiment and their graphical display. The use of 3D graphs is considered as in the case of visualization of three-dimensional vector fields in Matlab: force lines of electric and dipole field strength and potential of electric dipole field. For 3D graphics, the use of height and color gradients significantly increases the visibility of images. Graphic method in combination with information technology has a very high potential in the implementation of the main objectives of teaching physics.

This study presents an analytical method to identify the transversally connected natural landscape mosaics (TCNLMs) being in physical contact with the water surfaces of the territory at the metropolitan scale. It makes a comparative case between three Swedish cities; Helsingborg, Goteborg, and Malmo utilizing Urban Atlas land cover geospatial data and QGIS software. Fundamentally, the analytical process is based on the physical relationship the natural surfaces have with the water surfaces. The assessment is based on the concept of “bands” instead of “buffer” zone in reference to water sources. The land cover surfaces in touch with water surfaces are categorized as band 1. The remaining surfaces that are adjacent with band 1, are categorized as band 2. Similarly, the remaining land cover surfaces can be classified into further bands. The reclassified patches by their band level, are introduced into an analytical process structured in three levels. First, the natural surfaces are filtered and the existing TCNLMs (public land) within the metropolitan area are identified. Second, the agricultural areas are joined with the natural surfaces in order to measure their impact in the enhancement of TCNLMs. At the third level, the method gives floor to the identification of potential artificial surfaces (private land), the naturalization/ restoration of which may extensively enhance the transversal connectivity of natural lands to water sources. The potential artificial and agricultural surfaces as private property are targeted as private land for ecosystem services especially for urban ecological issues and disaster risk reduction. The workflow of the study is structured in Graphical Modeler (QGIS 3), enabling easier reproducibility of the method to similar study areas. The results of the study show that the proposed method is useful in scanning the transversally connected mosaics of natural lands and their potential enhancement. Finally, it contributes to the development of GIS-based analytical methods in support of natural based solutions for metropolitan challenges.

156 Background: DUE-01 is a multi-centric observational study aimed at developing predictive models of genito-urinary toxicity and erectile dysfunction for prostate cancer patients treated with conventional (1.8-2Gy/fr, CONV) or moderate hypofractionation (2.5-2.7Gy/fr, HYPO). Current analysis focused on modelling the relationship between the risk of IPSS≥15 (IPSS15end) at the end of radiotherapy and clinincal/dosimetric risk factors. Methods: Planning data and relevant clinical factors were prospectively collected, including DVH/DSH referred to the whole treatment and to the weekly delivered dose (DVHw/DSHw). Best discriminating DVH/DSH parameters were selected by the differences between patients with/without IPSS15end=1 (t-test). Bootstrap variable selection techniques (300 resamples) in the framework of logistic backward feature selection was used to improve model building (El Naqa, IJROBP 2006). Graphical and quantitative analyses of the variable selection process applied to bootstrap data replicates was used to avoid underfitting/overfitting and to assess the final multivariable model. Results: 247 patients were available (CONV:116, HYPO:131). Seventy one out of 247 (28.7%) reported IPSS15end=1. The most predictive dosimetric tools were the absolute weekly delivered dose (DSHw and DVHw). DSHw and DVHw were alternatively inserted in the bootstrap variable selection flow, together with clinical risk factors. Due to the number of events, a logistic model containing six variables was accepted On the basis of observed frequency of variables in the top six positions, a model including basal IPSS (median OR=1.22, p=0.00001), use of anti-hypertensives (median OR=2.7, p=0.01), absolute bladder surface receiving more than 10.5 Gy/week (s10.5w, median OR=1.16, p=0.0001), and s12.5w (median OR=1.07, p=0.005), was choosen. AUC of this model was 0.80. Silmilar results were obtained when using DVHw. Conclusions: Basal IPSS, use of anti-hypertensive drugs, s10.5w/v10.5w and s12.5w/v12.5w are the main predictors of IPSS>=15 at the end of radiotherapy Bootstrap variable selection technique gives the modeler more insight into the importance and stability of the different variables selected and allows development of more robust models

Modeling source–sink interactions and carbohydrate partitioning in plants requires a detailed model of plant architectural development, in which growth and function of each organ is modeled individually and carbohydrate transport among organs is modeled dynamically. L-PEACH is an L-system-based graphical simulation model that combines supply/demand concepts of carbon partitioning with an L-system model of tree architecture to create a distributed supply/demand system of carbon allocation within a growing tree. The whole plant is modeled as a branching network of sources and sinks, connected by conductive elements. An analogy to an electric network is used to calculate the flow and partitioning of carbohydrates between the individual components. The model can simulate multiple years of tree growth and be used to demonstrate effects of irrigation, crop load, and pruning on architectural development, tree growth, and carbon partitioning. Qualitative model outputs are viewed graphically as the tree “grows” on the computer screen while quantitative output data can be evaluated individually for each organ or collectively for an organ type using the MatLab software.

In the years after 1870, two theories of color vision vied for primacy: the “trichromatic” theory and a four-color theory, also known as an “opponent” theory of color vision. Among scientists who participated in this debate, mathematician Christine Ladd-Franklin (1847–1930) made special use of graphics as a rhetorical template for reasoning and explanation. Her later work included figures modeled upon novel graphic representations of logical relationships to describe chemical reactions fundamental to visual processes. These and other illustrations demonstrate, in retrospect, how innovation in graphic notation can underlie shifts in the practice and perception of science.

This article describes an attempt to create open source LabVIEW software, equivalent to data collection and control software. The proposed solution uses GNU Radio, OpenCV, Scilab, Xcos, and Comedi in Linux. GNU Radio provides a user-friendly graphical interface. Also, GNU Radio is a software-defined radio that conducts experiments in practice using software rather than the usual hardware implementation. Blocks for data propagation, code deletion with and without code tracking are created using the zero correlation zone code (ZCZ, a combination of ternary codes equal to 1, 0, and –1, which is specified in the program). Unlike MATLAB Simulink, GNU Radio is open source, i. e. free, and the concepts can be easily accessed by ordinary people without much programming experience using pre-written blocks. Calculations can be performed using OpenCV or Scilab and Xcos. Xcos is an application that is part of the Scilab mathematical modeling system, and it provides developers with the ability to design systems in the field of mechanics, hydraulics and electronics, as well as queuing systems. Xcos is a graphical interactive environment based on block modeling. The application is designed to solve problems of dynamic and situational modeling of systems, processes, devices, as well as testing and analyzing these systems. In this case, the modeled object (a system, device or process) is represented graphically by its functional parametric block diagram, which includes blocks of system elements and connections between them. The device drivers listed in Comedi are used for real-time data access. We also present an improved PyGTK-based graphical user interface for GNU Radio.

In the past decade is widely discussed the problem of
 geometric and graphic training of students of technical universities
 in Russia. In 1980-2005 arose contradictions between traditional
 and innovative methods of teaching for descriptive geometry and
 engineering graphics. This marked the article Professor P.A. Tunakov,
 in which descriptive geometry was carried to a dying science. This
 radical statement in subsequent years was supported by V.A. Rukavishnikov
 [15; 16] and A.L. Kheifets. An additional impetus to
 discussions was given by the developers of the Federal state educational
 standards of higher education (FSES), which declared the
 competence approach to the process of learning and evaluation of
 knowledge of graduates. Introduction in educational process of
 computer graphics
 and the appearance of technologies of 3D modeling
 prompted some representatives of the departments of engineering
 graphics towards the radical statements:
 • descriptive geometry as a graphic discipline became "moribund",
 "morally obsolete";
 • it is necessary to refuse from the method of projection, as
 "fundamentally important is a matter of conformity to the dimension
 of the three-dimensional computer model and the
 modeled object".
 The article proves the incorrectness of these statements. History
 and background of transformation of the descriptive geometry in
 the engineering geometry are shown:
 1) references to the dynamics of change subjects of presentations
 at the Moscow seminars on descriptive geometry and on engineering
 graphics during 1944–1965; the themes of dissertations
 on the specialty 05.01.01 engineering geometry and computer
 graphics (up to 1977 – applied geometry and engineering graphics);
 2) the requirements of competence-based learning model to establish:
 • intrasubject links (combination of synthetics and analytical
 methods of problem solving);
 • interdisciplinary connections by expanding the subject of
 the discipline of the multidimensional shapes;
 3) the incorrectness of opposing the "by the radicals" of 2D and
 3D models, for they are complementary the types of modeling
 single method of two images.

<p><strong>Abstract.</strong> This presentation presents a dialectical approach for the analysis and synthesis of geovisual communication systems using the graphic variables of Jacques Bertin as the primary analytical structure. This approach to studying geovisual communication accounts for its dynamics and interaction. It builds primarily on semiotic concepts advanced by Roland Barthes and Umberto Eco that emphasize the interactions between author and reader and the cultural circulation of knowledge. It relies on a Kantian critical epistemology to move beyond an instrumental description of a graphics-based system of communication. The visual system of affordances made and understood with a geovisualization produces situative meaning involving signification and interpretation, which is neither static nor discrete, but transforms what is known and what can be known. These conclusions lead to theoretical insights related to prior discursive concepts of visual communication and raise some questions for future research about the socio-cognitive affordances of cartographic visualization. A practical example shows the empirical approach and initial validation.</p><p>Visual Variables Structure Communication</p><p>The seminal contributions of Roland Barthes point to the process of embedding visual meaning regarding sign, signifier, signified, sign and concept as an extension to Saussure's dyadic approach as two semiological systems, which accounts for the importance of Saussure's bar in the communication of meaning. The two systems code the knowledge of communication, accounting for the situatedness of meaning and its discursive making that connects a sign to a cultural context. Umberto Eco goes beyond Pierce’s icon, index, and symbol trichotomy of a sign through an ongoing chain of interpretative referrals. This approach starts with an active collaboration between creator and reader. It can involve multiple circumstances, cultural aspects and evolve. Visual variables structure communication in an ongoing process.</p><p>The signification of a visual variable is analogous to an atom in a communication process. The analysis of the visual variables of a graphic element in a communication systems sense commences with an analysis of these visual variables related to individual elements and complex symbols. Barthes’ functions, actions, and narrative offer a valuable framework. A synthesis follows that considers the epistemological aspects of a partial system and what its functions purport to do and what they actually do. The analytically determined relationships can be synthesized into webs of explicit and implicit meanings associated with Barthes' structure. This combination and visual intermingling of graphic representations in a geovisualization broaden then to consider their interactions and associations with creator and reader. The visual encompasses the semiotic communication of meaning. The dialectical and critical consideration of the relations and the structure of the communication leads to an improved comprehension of the affordances manifest in the graphical communication system. It also begins to account for mental aspects of perception.</p><p>A model of geovisual communication?</p><p>The theory and methods of this semiotic approach involve considering Bertin’s graphical variables as elements of a model that corresponds to the communication system. Further, the structure of the geovisualization can be modeled symbolically to take up the questions how coding and decoding take place and made reliable given the dynamics of communication and the reliance on conventions in most cartography. This presentation closes with a summary of the benefits of a semiotic approach to the analysis and teaching of geovisual communication.</p>

The growth of psychrotrophic Bacillus cereus 404 from spores in boiled rice was examined experimentally at 15, 20, and 30°C. Using the Gompertz function, observed growth was modeled, and these kinetic values were compared with kinetic values for the growth of mesophilic vegetative cells as predicted by the U.S. Department of Agriculture's Pathogen Modeling Program, version 5.1. An analysis of variance indicated no statistically significant difference between observed and predicted values. A graphical comparison of kinetic values demonstrated that modeled predictions were “fail safe” for generation time and exponential growth rate at all temperatures. The model also was fail safe for lag-phase duration at 20 and 30°C but not at l5°C. Bias factors of 0.55, 0.82, and 1.82 for generation time, lag-phase duration, and exponential growth rate, respectively, indicated that the model generally was fail safe and hence provided a margin of safety in its growth predictions. Accuracy factors of 1.82, 1.60, and 1.82 for generation time, lag-phase duration, and exponential growth rate, respectively, quantitatively demonstrated the degree of difference between predicted and observed values. Although the Pathogen Modeling Program produced reasonably accurate predictions of the growth of psychrotrophic B. cereus from spores in boiled rice, the margin of safety provided by the model may be more conservative than desired for some applications. It is recommended that if microbial growth modeling is to be applied to any food safety or processing situation, it is best to validate the model before use. Once experimental data are gathered, graphical and quantitative methods of analysis can be useful tools for evaluating specific trends in model prediction and identifying important deviations between predicted and observed data.

AbstractFunction models are frequently used in engineering design to describe the technical functions that a product performs. This paper investigates the use of the functional basis, a function vocabulary developed to aid in communication and archiving of product function information, in describing consumer products that have been decomposed, analyzed, modeled functionally, and stored in a Web-based design repository. The frequency of use of function terms and phrases in 11 graphical and 110 list-based representations in the repository is examined and used to analyze the organization and expressiveness of the functional basis and function models. Within the context of reverse engineering, we determined that the modeling resolution provided by the hierarchical levels, especially the tertiary level, is inadequate for function modeling; the tertiary terms are inappropriate for capturing sufficient details desired by modelers for archiving and reuse, and there is a need for a more expressive flow terms and flow qualifiers in the vocabulary. A critical comparison is also presented of two representations in the design repository: function structures and function lists. The conclusions are used to identify new research opportunities, including the extension of the vocabulary to incorporate flow qualifiers in addition to more expressive terms.

The practice of designing centrifugal compressors in which impellers are the main components shows that there are reserves for their further improvement. One of the main reserves consists in improving flow conditions for the compressed medium in the compressor setting and, above all, in the impeller. A method of geometric modeling settings of the impellers of centrifugal compressors was proposed which involves the construction of meridional boundaries of impellers and the blade profile on an involute of the cylindrical surface of the outer radius of the impeller. The blade is represented by ruled surfaces. The outer boundary of the impeller is described by a curve in natural parameterization using cubic dependence of curvature on the arc length. Dependences and length of the arc are determined in the process of modeling the boundary based on the set source data. The problem is solved by minimizing deviations of intermediate curves from the boundary endpoint. The inner boundary is obtained as an envelope of circles inscribed in the meridional channel of the impeller. Radii of the circles are determined taking into account the flow areas of the channel. The midline of the blade profile on an involute of the cylindrical surface of the outer radius of the impeller is modeled using a curve that is presented in natural parameterization with quadratic law of curvature distribution. A computer code was developed in the Fortran Power Station programming environment that visualizes the obtained numerical results graphically on a computer display in addition to digital information on the modeled boundaries and the blade profile. Graphical results were presented. They confirmed the efficiency of the proposed method of modeling the settings of centrifugal compressor impellers. The method can be useful to offices involved in the design of centrifugal compressors

The need arises in parallel downloads of multilingual information for powerful graphical and analytical tools, as information with a variety of different languages distributed in different Web pages and the databases are heterogeneous and uneven in data grid. Petri net is a powerful graphical and mathematics tool for describing the concurrent, asynchronous and dynamic events. The parallel downloading of multilingual information was modeled and analyzed using extended timed colored Petri net (ETSdCPN). In ETSdCPN model, the color represents different languages information, and the time duration associated with place instead of transition is a function of tokens instead of constant. The reachable parallel download graph (RPDG) of ETSdCPN is defined. Finally, some important results such as rate of satisfaction and makespan of multilingual information parallel downloads are gotten by analyzing reachability of Petri net.

Simulink is widely used within the industry for simulation and model-driven development, and reactive behaviors are often modeled using an add-on called Stateflow. Argos is one of the synchronous languages that have been proposed for the specification, validation and implementation of reactive systems. It is a rigorously defined graphical notation which, though not as powerful as Stateflow, is much less complicated. This paper describes the implementation of an Argos block for Simulink.

We study for the first time how a new class of stars could impact an ensemble of pulsars with known masses and spin-periods. These new compact objects are strange stars admixed with condensed dark matter (DM). In this exploratory theoretical work, our goal is to determine how the basic parameters of pulsars are modified for such a new class of compact objects. In particular, we consider three different scenarios that correspond to a DM mass fraction of [Formula: see text], [Formula: see text] and [Formula: see text]. Within each scenario with fixed parameters, we predict theoretically other properties of the pulsars, such as the radius, the compactness, the moment of inertia, as well as the angular momentum. Our numerical results are summarized in tables and also shown graphically for better visualization, where a comparison between the different scenarios can be made.

Fact-oriented modeling approaches such as Object-Role Modeling (ORM) include a rich graphical notation for capturing business constraints, allowing modelers to visualize fine details of their data models. These data models should be validated with domain experts who best understand the business requirements, even if unfamiliar with the graphical notation. Hence, the data models are best validated by verbalizing the models in a controlled natural language, and by populating the relevant fact types with examples. Comparatively little support exists for verbalizing fact-based models in non-English languages, especially Asian languages. This paper describes the authors' work on verbalizing ORM models in Bahasa Melayu (Malay) and Mandarin. The authors specify some typical transformation patterns, discuss features of these languages requiring special treatment (e.g. noun classifiers, repositioning of modal operators, and different uses for terms equivalent to “who” and “that” in English), and describe their current implementation efforts.

SUMMARYA direct subspace of a dynamic three-dimensional joint space is found to be useful for robot path planning in workspaces comprised of both static and dynamic objects. Dynamic descriptions permit positioning tables, automated guided vehicles, conveyors and cycling machine tools to be modeled by elements which translate or cycle along rectilinear paths. Graphical path planning procedures use cursor indicators to move the robot configuration point between the desired starting and final configurations while avoiding both the static and dynamic joint space obstacles.

One of the possible methods for transport stream modeling is by using Petri's nets [1,2]. This approach turns out to be very convenient for achieving the desired tasks because of the following reasons: the Petri's nets [3] are based on causal-consequence connections found in abundance in transport problems and the graphical representation by means of the net elements is easily percieved by man, i.e. there an easy way of visualisation of the transport problem under consideration. Examples will be given of how transport problems are modeled.

It is found that the velocity and temperature with constant proportional Capu?to fractional derivative are portrait better decay than velocities and temperatures that obtained with Caputo and Caputo-Fabrizio derivative. Further, rate of heat transfer and skin friction can be enhanced with smaller values of fractional parameter.
