Full textAbstract:
The article is intended to propose the new technique for analysis and visualization of vectorcardiograms based on the 3D phase diagrams. The regular Frank 3D lead system was considered as the signal source to construct 3D vector space. The three cardio signals from the lead system, representing the currents in the body, and the three integrated in time signals, representing the corresponding charge flows, were used to form 3D phase diagram. This diagram is considered as a new compact description of the dipole object properties in the 3D space, combining simultaneously information about the charge movements and the changes in values and orientation of the current. The regular properties, like the angular momentum of the charge flow and the dipole strength vectors and their covariance can be evaluated from the real vectorcardiogram. Based on the set of vectorcardiograms for 8 healthy controls and 7 myocardial infarction patients the 3D phase diagrams and their statistical parameters are evaluated and discussed. An example is given of the technique implementation for the comparison of the 3D phase diagrams in a control and a myocardial infarction patient.

A group-based sharia savings and loan cooperative is different with the common cooperatives out there. This unique cooperative’s process business made its staff not being able to use a usual cooperative information system without being customized. A SWOT analysis has been conducted to decide whether this kind of cooperative need to develop a new information system or not. The results showed that a new information system is definitely needed. An information system of sharia-based savings and loan cooperative with special features to handle group transactions of cooperative members has been designed and developed, although it’s not yet perfect, to help ease the staffs’ workloads. User centered design approach was used to develop this information system since the users are the ones who know best what they need and do. Several diagrams were created to design the system, such as: use case diagram, architecture system diagram, data flow diagram, entity relationship diagram, and the user interface mockup. This information system has several main modules, such as: Member Service, Transaction, Authorization, Back-Office, Reports, and System Configuration. Blackbox tests have been done to test whether the system is functioning properly or not.

The growing interest of companies in integration and interoperability between information systems has caused increase in significance of Service-Oriented Architecture which provides tools for Enterprise Application Integration. In that architecture, Enterprise Service Bus provides technical possibilities of communication between IT systems. A key element in the communication are integration flows. Objective: The aim of this article is to present a new transformation Integration2BPEL, which automates the development of executable integration flow expressed in the Web Services Business Process Execution Language (WS-BPEL) based on the model of the integration flow presented in the Unified Modelling Language (UML) activity diagram. Method: The author proposes a transformation of the type of model-to-code type which generates integration flow expressed in WS-BPEL, which can be executed in any BPEL-compliant process engine. The integration flow is modelled using UML activity diagram with stereotypes from ‘UML Profile for Integration Flows’ profile in an IBM Rational Software Architect (RSA). Using Integration2BPEL transformation a complete, executable integration flow is generated, which is composed of many mediation mechanisms. Generated integration flows have been executed on OpenESB. Results: The ability to generate a complete integration flow in BPEL, which without any additions can be run on enterprise service bus. Implementation phase of an integration flow construction was automated. Each of integration flows is implemented according to the same rules. In addition, it allows to avoid mistakes made by designers and programmers. Conclusions: Model-Driven Development is an approach that leads to the automation of the design and programming phases. Integration2BPEL transformation is a uniform mechanism to design integration flow. Potentially, it also allows to avoid implementation errors.

Abstract A comprehensive framework is presented for analyzing and specifying an extensive range of visualizations, such as statistical charts, maps, family trees, Venn diagrams, flow charts, texts using indenting, technical drawings and scientific illustrations. This paper describes how the fundamental ‘DNA’ building blocks of visual encoding and composition can be combined into ‘visualization patterns’ that specify these and other types of visualizations. We offer different ways of specifying each visualization pattern, including through a DNA tree diagram and through a rigorously systematic natural language sentence. Using this framework, a design tool is proposed for exploring visualization design options.

Entity relationship diagram (ERD) and data flow diagram (DFD) modeling are necessary parts in analysis and design of structured information systems in business. Definition of entities in the ERD, the process, and datastore in the DFD have well described in a lot of literatures. However, practically it is not easy to explain how to design ERD and DFD models so that the students well understand the modeling steps, especially in business applications. This study discussed step-by-step systematic approach to ERD and DFD modeling using "business event-driven" approach that is represented by the REA model, through structuring REA-ERD and REA-DFD. From the results we concluded that the logical design of ERD should be done before designing DFD, so that there would be perfect "balancing" between the entities in the ERD and data stores in the DFD. Consequently, the implementation of these steps needed to be tested both qualitatively and quantitatively in advanced researches

Abstract. Regionalisation provides a way of transferring hydrological information from gauged to ungauged catchments. The past few decades has seen several kinds of regionalisation approaches for catchment classification and runoff predictions. The underlying assumption is that catchments having similar catchment properties are hydrological similar. This requires the appropriate selection of catchment properties, particularly the inclusion of observed hydrological information, to explain the similarity of hydrological behaviour. We selected observable catchments properties and flow duration curves to reflect the hydrological behaviour, and to regionalize rainfall-runoff response for runoff prediction. As a case study, we investigated 15 catchments located in the Yangtze and Yellow River under multiple hydro-climatic conditions. A clustering scheme was developed to separate the catchments into 4 homogeneous regions by employing catchment properties including hydro-climatic attributes, topographic attributes and land cover etc. We utilized daily flow duration curves as the indicator of hydrological response and interpreted hydrological similarity by root mean square errors. The combined analysis of similarity in catchment properties and hydrological response suggested that catchments in the same homogenous region were hydrological similar. A further validation was conducted by establishing a rainfall-runoff coaxial correlation diagram for each catchment. A common coaxial correlation diagram was generated for each homogenous region. The performances of most coaxial correlation diagrams met the national standard. The coaxial correlation diagram can be transferred within the homogeneous region for runoff prediction in ungauged catchments at an hourly time scale.

In this paper, we propose a new logistic map based on the relation of the information entropy, we study the bifurcation diagram comparatively to the standard logistic map. In the first part, we compare the obtained diagram, by numerical simulations, with that of the standard logistic map. It is found that the structures of both diagrams are similar where the range of the growth parameter is restricted to the interval [0,e]. In the second part, we present an application of the proposed map in traffic flow using macroscopic model. It is found that the bifurcation diagram is an exact model of the Greenberg’s model of traffic flow where the growth parameter corresponds to the optimal velocity and the random sequence corresponds to the density. In the last part, we present a second possible application of the proposed map which consists of random number generation. The results of the analysis show that the excluded initial values of the sequences are (0,1).

Abstract:Physicians need specially tailored computer tools to take advantage of published research results. We present a knowledge-based computer framework -the physician-based (PB) architecture - for constructing such tools, and we use the problem of physicians’ interpretation of two-arm parallel randomized clinical trials (TAPRCT) as a working example. Statistical models are represented by influence diagrams. The interpretation of influence-diagram elements are mapped into users’ language in a domain-specific, physician-based user interface, called a patient-flow diagram. Statistical-model transformations that maintain the semantic relationships of the model and that embody clinical-epidemiological knowledge are encoded in a mediating structure called the cohort-state diagram. The algorithm that coordinates the interactions among the knowledge representations uses modular actions called construction steps. This architecture has been implemented in a Bayesian system, called THOMAS, that supports physician decision making in light of TAPRCT data. This support entails assessing clinical significance, prior beliefs, and methodological concerns. We suggest that the PB architecture applies to a wide range of statistical tools and users.

Full textAbstract:
The application of cosegmentation in remote sensing image change detection can effectively overcome the salt and pepper phenomenon and generate multitemporal changing objects with consistent boundaries. Cosegmentation considers the image information, such as spectrum and texture, and mines the spatial neighborhood information between pixels. However, each pixel in the minimum cut/maximum flow algorithm for cosegmentation change detection is regarded as a node in the network flow diagram. This condition leads to a direct correlation between computation times and the number of nodes and edges in the diagram. It requires a large amount of computation and consumes excessive time for change detection of large areas. A superpixel segmentation method is combined into cosegmentation to solve this shortcoming. Simple linear iterative clustering is adopted to group pixels by using the similarity of features among pixels. Two-phase superpixels are overlaid to form the multitemporal consistent superpixel segmentation. Each superpixel block is regarded as a node for cosegmentation change detection, so as to reduce the number of nodes in the network flow diagram constructed by minimum cut/maximum flow. In this study, the Chinese GF-1 and Landsat satellite images are taken as examples, the overall accuracy of the change detection results is above 0.80, and the calculation time is only one-fifth of the original.

Full textAbstract:
Using Cornell’s supercomputing facilities, we have carried out an extensive study of the Moore–Greitzer model, which gives accurate and reliable information about compressor instability. The bifurcation analysis in the companion paper shows the dependence of the mode of compressor response on the shape of the rotating stall characteristic. The numerical results verify and extend this with a more accurate representation of the characteristic. The effect of the parameters on the shape of the rotating stall characteristic is investigated, and it is found that the parameters with the strongest effects are the inlet length, and the shape of the compressor pressure rise versus mass flow diagram (i.e., tall diagrams versus shallow diagrams). We also discuss the effects of inlet guide vane loss on the characteristic. An evaluation is made of the h′ = −g approximation, and a spectral analysis of the rotating stall cell given by the full model suggests why this breaks down.

Full textAbstract:
The authors cannot comprehensively determine all of the vulnerabilities to an attack only from requirements descriptions. To resolve the problem, the authors propose a method for eliciting security requirements using the information about system architecture. The authors convert a use-case description into a variation of a data flow diagram called an asset-flow diagram (AFD). The authors then refine the AFDs based on a processor deployment diagram (PDD), which gives information about a system architecture. By using vulnerabilities patterns to an attack, the authors distinguish vulnerabilities to the attack that can be identifiable in AFDs from remaining vulnerabilities to the attack. To prohibit the former vulnerabilities, security requirements are defined as countermeasures and/or modification of existing requirements. To prevent the latter vulnerabilities, security requirements are defined as design and implementation constraints. Through an evaluation of a web application, the authors show that our method enables us to elicit security requirements against several different attacks in different system architectures.

 Introduction. A relatively new form of transformation of the territory in the current urban development, the renovation of quarters, requires close scientific study and methodological justification. Renovated neighborhoods, as well as projects for the construction of new houses, have individual features and characteristics. The authors hypothesize that, despite the variety of characteristics of renovated neighborhoods and projects for the construction of new houses, traditional in-line construction with the allocation of characteristic stages is possible.
 
 Materials and methods. To study the actual duration of the stages of creating objects under the renovation program (which is necessary to identify objects of similar duration), a special database was formed in the Scientific and Project Center “City Development”. As of 15.05.2021, 313 objects involved in the renovation program are included in this special database. A thorough verification of the specified database was performed. As a result, 122 objects with a spread of construction duration values from 11 months to 43.2 months are stored in the verified database. In addition, the materials of the information system for ensuring urban planning activities (ISOGD) of Moscow were used. The initial materials allowed us to identify a number of characteristic stages in the renovation program for each object.
 
 Results. To analyze the design duration of construction, the set of objects is divided into 2 parts: commissioning in 2021 and commissioning in subsequent years. For each part, histograms of the distribution of the duration of construction of houses during renovation are constructed and it is proved that the law of normal distribution is observed. A schematic model of renovation processes with multiple process durations is presented. The overall duration of the design (project stage) can take 1 year, construction — 2 years, and the combined stages: preparation of documents, relocation and demolition, will approximately take 1 year. This four-year wave cycle is then repeated the required number of times. The calendar plan of renovation for three wave objects with the allocation of the leading stream is presented. The ratio of flow processes during renovation is most clearly reflected in the constructed cyclogram of a multi-rhythmic object flow modified for renovation conditions. Combined schedules of renovation of in-line construction are constructed.
 
 Conclusions. Despite the considerable variety of renovated neighborhoods and projects for the construction of new houses, the authors of the article prove that traditional in-line construction with the allocation of characteristic stages is possible. For large contracting organizations, it is realistic to form a multi-rhythmic object flow with the allocation of the construction stage as the leading flow and calculate the renovation cyclogram.

Full textAbstract:
Vehicular trajectories are firstly achieved on the basis of vehicle time and space information obtained from VISSIM simulation. Via simulating setting loop detectors at different locations and collecting traffic data in different time intervals, different traffic flow fundamental diagrams on the basis of the detect data are then generated. Finally, comparing these fundamental diagrams, two conclusions are achieved. The loop detective interval has a significant impact on fundamental diagrams while the detector location has an extremely limited influence. Particularly, fundamental diagram is more aggregated with longer data collecting interval and capacity is more easily to be obtained with longer distance between neighboring loop detectors.

In this fast-paced era, the need for precise, fast, and accurate information is something that must be done. Effectiveness and efficiency should be carried out according to needs so that the information can be relevant to its users. Thus, the registration information system, which has been manual in agencies or organizations, can be changed to online with accurate and timely data. Likewise, the Tamansari Religious Affairs Office in Bogor Regency. The current marriage registration system at the Tamansari Bogor Regency Office of Religious Affairs is no longer in line with the current development. The current system does not use computers as data processing tools, the results are still not well structured. Especially for processing the data of the prospective bride and groom. In this system, what is processed is registration data, bridal data, guardian data, witness data, admin data, and other data. The problem that occurs at this time is that the processed data feels slow, the resulting report has to pass data collection several times. In the information system to fulfill this final project, we will explain how to design and build a web-based marriage registration information system. The tools used in designing this system are MySQL, Entity Relational Diagrams, and Data Flow Diagrams, while for data collection using observation, interviews, and literature study. Meanwhile, database application development tools use MySQL and the programming language uses PHP. From this application, the benefits of data processing of brides, guardians, witnesses, etc. will be automatically obtained. Reports can also help by showing what is needed to process data quickly and easily.

Full textAbstract:
For automation of many software engineering tasks such as program analysis, testing, and coverage analysis, it is necessary to construct a control flow graph. With the advancement of UML, software practitioners advocate to construct control flow graph from some of the UML design artifacts. UML 2.x supports the modeling of control flow information in interaction diagram by means of message sequences and different types of fragments like alt, opt, break, loop, and so forth. Leading UML modeling tools, namely MagicDraw, IBM's Rational, and so forth export models in XMI format. Construction of control flow graph from the XMI representation of an interaction diagram is not straightforward as model elements of interaction diagram are captured in XMI by means of values of attributes of multiple tagged elements and correlations among these tagged elements is not explicitly specified. This paper proposes an approach for construction of control flow graph from XMI representation of UML 2.x interaction diagram. A prototype tool based on our approach has been developed which can be plugged in any computer-aided software engineering tool.

Full textAbstract:
The construction industry is highly fragmented. A large number of diverse organizations participate in the planning, design, and construction of each constructed project. Cooperation between project participants necessitates the transfer of large quantities of project information. Communication, in many forms, is the means for data exchange among participants. Availability and timeliness of the data needed to perform different project tasks may decrease the potential for project delay(s) and rework, thus increase productivity. This paper discusses the use of the "structured analysis" methodology to document the communication process. The paper also discusses the use of a shared-data resource to solve some of the communication and standardization problems in the construction industry. An overview of the structured analysis methodology is provided. Data flow diagrams, a data dictionary, and transform descriptions comprise the tools for implementing structured analysis. Each tool is briefly described with emphasis given to data flow diagrams. Portions of the communication process documented for a highway bridge project administered by Wisconsin Department of Transportation are provided as an example to illustrate the use of data flow diagrams for information flow identification. The example also presents the use of the data dictionary as a supplementary document to provide composition and definition of data elements. Selected communication difficulties among project participants as well as potential areas of modifications and (or) automation in the current system are highlighted. This paper provides a framework for tracking and documenting the information flow between project participants. Key words: data flow model, data flow diagram, bridge construction, structured analysis, communication.

The article proposes, shows and analyzes the main stages of implementing software for group assessment of a functional profile and determining or agreeing the level of guarantees for the correct implementation of functional security services in information security tools of information of telecommunication systems from unauthorized access in Ukraine based on theoretical studies previously conducted. The necessary regulatory documents on technical protection of information governing the procedure of evaluating and determining the level of guarantees of automated systems against unauthorized access in Ukraine are covered. The program was designed using the Data Flow Diagram, namely, a contextual diagram of the group definition process and a decomposed diagram of the process of group determination of the functional security profiles and the level of guarantees. More detailed flowcharts of software and algorithms are constructed. A prototype of the software is implemented; examples of work on each of the main blocks of work that were previously designed in the diagrams and flowcharts of the algorithms are given. Certain advantages and disadvantages of the developed software for group determination of the functional security profile and the level of guarantees are defined. The developed program allows to carry out group estimation and to compare the results sent to the server. This approach reduces the time spent by the security administrator to determine the security profiles and security levels of the information being processed against unauthorized access and to detect whether a specified functional profile coincides with a standard one (provided this match the user is provided with information about that standard functional profile) or determine another level of warranty. By conducting a group examination, the reliability of the obtained results increases

Full textAbstract:
String diagrams are a powerful and intuitive graphical syntax, originating in theoretical physics and later formalised in the context of symmetric monoidal categories. In recent years, they have found application in the modelling of various computational structures, in fields as diverse as Computer Science, Physics, Control Theory, Linguistics, and Biology. In several of these proposals, transformations of systems are modelled as rewrite rules of diagrams. These developments require a mathematical foundation for string diagram rewriting: whereas rewrite theory for terms is well-understood, the two-dimensional nature of string diagrams poses quite a few additional challenges. This work systematises and expands a series of recent conference papers, laying down such a foundation. As a first step, we focus on the case of rewrite systems for string diagrammatic theories that feature a Frobenius algebra. This common structure provides a more permissive notion of composition than the usual one available in monoidal categories, and has found many applications in areas such as concurrency, quantum theory, and electrical circuits. Notably, this structure provides an exact correspondence between the syntactic notion of string diagrams modulo Frobenius structure and the combinatorial structure of hypergraphs. Our work introduces a combinatorial interpretation of string diagram rewriting modulo Frobenius structures in terms of double-pushout hypergraph rewriting. We prove this interpretation to be sound and complete and we also show that the approach can be generalised to rewriting modulo multiple Frobenius structures. As a proof of concept, we show how to derive from these results a termination strategy for Interacting Bialgebras, an important rewrite theory in the study of quantum circuits and signal flow graphs.

Full textAbstract:
The development of an effective hydraulic unit (HU) diagnostic system, which recognizes critical fault at an early stage of their development, is a relevant and practically important objective for many hydroelectric power plants (HPP). The main trends in recent years in this area are the expansion of the hardware base and the introduction of digital technologies to handle the increasing flow of data monitoring. At the same time, much less attention is paid to the improvement of algorithms for potential defect recognition and the creation of new diagnostic rules; much of the monitoring data are used only for the trend construction, and do not participate in the diagnosis. The method of vector diagrams is proposed for estimating actual forces applied towards the support joints of an HU: each mode of operation is represented on a phase plane in the form of a vector proportional to the vibration displacement. The vector difference determines the actual forces of mechanical, electromagnetic and hydraulic origin in each operating mode, taking into account the individual characteristics of the HU. The example of vector diagram analysis shows how to obtain more useful information about the technical status of the unit from the same amount of basic vibration monitoring data, to predict possible deterioration in the operation of the equipment well before the generation of a warning or an alarm signal by the diagnostic system.

By using a large data-base of single vehicle data from a German freeway, the fundamental diagram (FD) can be extended. These types of data allow extraction of additional information that can be displayed as a function of the traffic flow [Formula: see text] and speed [Formula: see text]. This is demonstrated here with a surrogate measure of safety (SMoS) and two other indices, which can be used to perform more in-depth analyses of traffic flow. In the case of the SMoS, it is possible to identify more and less dangerous regions in the extended FD.

Abstract
 
 Behaviour movement of vehicles on the highway segment is the basis for the development of a lot of traffic modeling. Development of traffic modeling on the number of vehicles is used macroscopically for an extensive road network. This study aims to find the relationship between the level of service to the fundamental diagram. Therefore, this relationship can be used to develop information systems for the transportation stakeholders or control the current flow on the freeway. The next research goal focuses on determining the average speed of vehicles effectively based on the level of service. Specific relationship between macroscopic parameters for specific traffic conditions on a single road section occurs when steady state conditions and equilibrium conditions were achieved. Average traffic conditions practically were taken on the measurements of macroscopic parameters after steady state is reached and valid. Modeling was obtained based on mapping the equilibrium conditions. The diagram between the macroscopic parameter is called the Fundamental Traffic Diagram for road segments. The results of the research showed that the highest vehicular traffic flow conditions gives maximum density of vehicles. If the average speed of vehicles on the condition of free flow determined in accordance maximum design speed of 120 km/h, the headway and each vehicle gap would be 1.5 seconds and 50 meters, respectively. It is very meaningful for policy makers to determine the flow traffic pattern and transport engineering.

 Perilaku pergerakan banyak kendaraan pada ruas jalan bebas hambatan menjadi dasar bagi pengembangan banyak pemodelan lalu-lintas. Pengembangan pemodelan lalu-lintas jumlah kendaraan secara makroskopik dipergunakan pada jaringan jalan yang luas. Penelitian ini bertujuan untuk menemukan hubungan antara tingkat pelayanan jalan dengan diagram fundamental. Dengan demikian hubungan ini dapat dimanfaatkan untuk mengembangkan sistem informasi bagi pemangku kepentingan transportasi ataupun pengendalian aliran arus pada jalan bebas hambatan. Tujuan penelitian berikutnya menitik beratkan pada penentuan kecepatan rata-rata banyak kendaraan efektif berdasarkan tingkat pelayanan jalan. Hubungan spesifik antar parameter makroskopik untuk kondisi lalu lintas tertentu pada satu ruas jalan tunggal terjadi pada saat kondisi keadaan mantab dan kondisi equilibrium. Kondisi lalu lintas rata-rata secara praktis diambil pengukuran parameter makroskopik setelah kondisi stabil tercapai dan valid. Pemodelan yang diperoleh berdasarkan pada pemetaan kondisi equilibrium. Pada diagram antar parameter makroskopik tersebut disebut sebagai Diagram Fundamental Lalu-Lintas bagi ruas jalan. Hasil penelitian menunjukkan bahwa pada kondisi aliran arus kendaraan tertinggi diperoleh kepadatan kendaraan maksimum. Apabila kecepatan rata-rata banyak kendaraan pada kondisi arus bebas (free flow) ditetapkan sesuai kecepatan maksimum desain yaitu 120 km/jam, maka diperoleh headway dan gap masing-masing kendaraan adalah 1,5 detik dan 50 meter. Diagram Fundamental Polinomial yang terjadi dapat membantu bagi pengambil kebijakan untuk menentukan pola aliran arus kendaraan, pengendalian optimal dan rekayasa transportasi.

Several previous studies have used the Cellular Automaton (CA) for the modeling of bicycle traffic flow. However, previous CA models have several limitations, resulting in differences between the simulated and the observed traffic flow features. The primary objective of this study is to propose a modified CA model for simulating the characteristics of mixed bicycle traffic flow. Field data were collected on physically separated bicycle path in Shanghai, China, and were used to calibrate the CA model using the genetic algorithm. Traffic flow features between simulations of several CA models and field observations were compared. The results showed that our modified CA model produced more accurate simulation for the fundamental diagram and the passing events in mixed bicycle traffic flow. Based on our model, the bicycle traffic flow features, including the fundamental diagram, the number of passing events, and the number of lane changes, were analyzed. We also analyzed the traffic flow features with different traffic densities, traffic components on different travel lanes. Results of the study can provide important information for understanding and simulating the operations of mixed bicycle traffic flow.
