The article examines the essence of the institutional and functional architecture of industrial development strategic planning, which is an ordered system of relations between various institutions in course of designing the industrial strategy. The goal of the article is to identify the features of the functional and institutional architecture of strategic planning and to determine their impact on strategic decision-making processes in the field of industrial development. The main modules of strategic planning architecture are singled out. In particular, they include responsibility centers (which can be the Ministry of Economy of Ukraine or the Ministry of Strategic Industries of Ukraine) and stakeholders, as well as their roles and functions, legislation, and flows of information and analytical data. It was revealed that there are six main functions organizations perform during the strategic planning: framework goals of higher level; strategic goal setting; analysis of environment; strategic alternatives assessment; distinction of steering and planning functions; relationship between planning and budgeting. While the government has its own vision of strategic goals which depends on the political and technical performance of the responsible institution, it is important to engage various government and non-government institutions and business in strategic planning industry development. This idea was also supported within the models of strategic decision making – the model of strategic choice oriented on internal institutional capabilities and external control model which argues the external determinants highly contribute to the variation of the strategic alternatives assessment should be combined. In Ukraine main stakeholders can be represented by business associations and trade unions, R&D institutions and universities, think tanks and civil society organizations. Organizations providing statistical and analytical information also play an important role. There were determined several ways of stakeholders’ involvement in strategic planning of industry development – through participation in working group, through public discussion and through public inquiries preparing experts assessments. Ensuring transparency and efficiency of inter-institutional interaction, trust and support from key stakeholders is also an important component for stimulating systemic change. As a result of these findings the model of functional and institutional architecture of strategic planning of industrial development was elaborated in the study.

Тестирование и компиляция моделей цифровых блоков в программно-аналитическим комплексе САПР

The article discusses the important stages of the process of developing a digital device of microelectronics associated with testing and compiling models of digital blocks. The work was carried out as part of the creation of a domestic CAD system designed for the design of various digital microelectronics devices. The presented works were carried out by VSFEU together with ROSELECTRONICS Holding. The authors have developed a model of a digital microprocessor based on SYNTACORE's SCR1 core, a 32-bit fully functional RISC-V architecture model with an IMC instruction set. To simulate the RTL model, an XCELIUM simulator with a SimVision visualization shell from Cadence was used, which allows a complete analysis of the RTL model. The core model was compiled using the Genus software from the Cadence development package. Next, the model was configured and optimized according to the time parameters according to the specified restrictions on the microprocessor being developed. It is important to note that effective testing and compilation of digital block models requires the use of specialized tools, such as automated testing tools and version control systems. This makes it possible to significantly speed up the development process and improve the quality of the final product. As a result, a package of files for Innovus software was formed to create a topology.

Construction of a Multimedia Education Resource Security Model Based on Multistage Integration

A security model of multimedia education resource fusion based on multistage integration of multimedia educational resources is constructed in this paper in the context of smart education. First, the teaching model of multimedia education resource fusion is analyzed and the IoT communication evolution model and functional architecture model are constructed accordingly, based on which the realization path of IoT intelligent sensing, intelligent management, emotional computing, device sharing, and vision simulation functions for smart education are discussed. The security model uses a decentralized cryptographic data security sharing method based on blockchain for protection and supports blockchain to record user attributes to ensure the confidentiality and integrity of data. The experimental and analytical results indicate that the scheme can effectively reduce the computational overhead of smart devices while ensuring the security of data sharing. Moreover, the proposed model in the paper achieves better performance than other methods in terms of security strength, encryption, and decryption time.

Modeling and analysis of civil aircraft top level RNP system architecture

In recent years, the international aviation organization has implemented new performance-based navigation technology and issued the operational requirements of required navigation performance (RNP). It involves the cross-linking of multiple complex systems, which puts forward higher requirements for aircraft development and management. In this paper, the development process of RNP functional architecture model is defined by using magic grid software. The modeling is completed from three aspects: problem domain, solution domain and implementation domain. The decomposition and implementation of complex functions are completed from top to bottom. This method can effectively solve the complexity problem of civil aircraft system, and lay the foundation for demand-based model forward design.

Retracted] Optimization of an Intelligent Music‐Playing System Based on Network Communication

Streaming media server is the core system of audio and video application in the Internet; it has a wide range of applications in music recommendation. As song libraries and users of music websites and APPs continue to increase, user interaction data are generated at an increasingly fast rate, making the shortcomings of the original offline recommendation system and the advantages of the real‐time streaming recommendation system more and more obvious. This paper describes in detail the working methods and contents of each stage of the real‐time streaming music recommendation system, including requirement analysis, overall design, implementation of each module of the system, and system testing and analysis, from a practical scenario. Moreover, this paper analyzes the current research status and deficiencies in the field of music recommendation by analyzing the user interaction data of real music websites. From the actual requirements of the system, the functional and performance goals of the system are proposed to address these deficiencies, and then the functional structure, general architecture, and database model of the system are designed, and how to interact with the server side and the client side is investigated. For the implementation of data collection and statistics module, this paper adopts Flume and Kafka to collect user behavior data and uses Spark Streaming and Redis to count music popularity trends and support efficient query. The recommendation engine module in this paper is designed and optimized using Spark to implement incremental matrix decomposition on data streams, online collaborative topic model, and improved item‐based collaborative filtering algorithm. In the system testing section, the functionality and performance of the system are tested, and the recommendation engine is tested with real datasets to show the discovered music themes and analyze the test results in detail.

Super-resolution microscopy approaches to nuclear nanostructure imaging.

The human genome has been decoded, but we are still far from understanding the regulation of all gene activities. A largely unexplained role in these regulatory mechanisms is played by the spatial organization of the genome in the cell nucleus which has far-reaching functional consequences for gene regulation. Until recently, it appeared to be impossible to study this problem on the nanoscale by light microscopy. However, novel developments in optical imaging technology have radically surpassed the limited resolution of conventional far-field fluorescence microscopy (ca. 200nm). After a brief review of available super-resolution microscopy (SRM) methods, we focus on a specific SRM approach to study nuclear genome structure at the single cell/single molecule level, Spectral Precision Distance/Position Determination Microscopy (SPDM). SPDM, a variant of localization microscopy, makes use of conventional fluorescent proteins or single standard organic fluorophores in combination with standard (or only slightly modified) specimen preparation conditions; in its actual realization mode, the same laser frequency can be used for both photoswitching and fluorescence read out. Presently, the SPDM method allows us to image nuclear genome organization in individual cells down to few tens of nanometer (nm) of structural resolution, and to perform quantitative analyses of individual small chromatin domains; of the nanoscale distribution of histones, chromatin remodeling proteins, and transcription, splicing and repair related factors. As a biomedical research application, using dual-color SPDM, it became possible to monitor in mouse cardiomyocyte cells quantitatively the effects of ischemia conditions on the chromatin nanostructure (DNA). These novel "molecular optics" approaches open an avenue to study the nuclear landscape directly in individual cells down to the single molecule level and thus to test models of functional genome architecture at unprecedented resolution.

A Cortical-Inspired Geometry for Contour Perception and Motion Integration

In this paper we develop a geometrical model of functional architecture for the processing of spatio-temporal visual stimuli. The model arises from the properties of the receptive field linear dynamics of orientation and speed-selective cells in the visual cortex, that can be embedded in the definition of a geometry where the connectivity between points is driven by the contact structure of a 5D manifold. Then, we compute the stochastic kernels that are the approximations of two Fokker Planck operators associated to the geometry, and implement them as facilitation patterns within a neural population activity model, in order to reproduce some psychophysiological findings about the perception of contours in motion and trajectories of points found in the literature.

Attentional modulation of fMRI responses in human V1 is consistent with distinct spatial maps for chromatically defined orientation and contrast.

Attending to different stimulus features such as contrast or orientation can change the pattern of neural responses in human V1 measured with fMRI. We show that these pattern changes are much more distinct for colored stimuli than for achromatic stimuli. This is evidence for a classic model of V1 functional architecture in which chromatic contrast and orientation are coded in spatially distinct neural domains, while achromatic contrast and orientation are not.

Feature Interaction Aware Test Case Generation for Embedded Control Systems

The growing number and increased coupling of functionality in embedded control systems, e.g. in the automotive domain, leads to complex networks of interacting features and a wide range of variants. Hence, today's software development processes must include systematic approaches to analyze the functional correctness of system specifications and implementations. Model-based testing is of particular importance for embedded software systems as the test cases can be performed at the real system under test and failures arising from the interaction of software and hardware can be discovered. As features are usually designed in a modular and isolated way, unexpected and undesired behavior caused by unintended interferences of insufficiently synchronized and even contradicting features concurrently active in the system often remains undetected which may lead to serious safety problems. To overcome such feature interactions at system integration level is tedious as it leads to a voluminous number of unmanageable test cases. We describe a model-based approach for efficiently generating test cases that particularly aim at feature interaction analysis. We first characterize feature interaction in a formal way based on a rigorous functional architecture model, and describe how to detect potential feature interactions. For test case generation, behavioral models like Statecharts and according coverage criteria can be used as usual, but only those models are integrated into the test model, that contribute to one of the features under consideration. This leads to a trade off between comprehensive test coverage to find possible flaws caused by interacting features, and yet still a reasonable number of test cases. The steps of the approach are illustrated be means of a case study from the automotive domain.

Semantic asymmetries are modulated by phonological asymmetries: Evidence from the disambiguation of homophonic versus heterophonic homographs

The present study investigated cerebral asymmetries in accessing multiple meanings of two types of homographs: homophonic homographs (e.g., bank) and heterophonic homographs (e.g., tear). Participants read homographs preceded by either a biasing or a non-biasing sentential context and performed a lexical decision on lateralized targets presented 150 ms after onset of the sentence-final ambiguous prime. Targets were either related to the dominant or the subordinate meaning of the preceding homograph or were unrelated to it. In the case of homophonic homographs – our results converge with previous findings: both activation and selection processes are faster in the LH than in the RH. Importantly, however, in the case of heterophonic homographs – opposite asymmetries were found. These results suggest that semantic asymmetries are modulated by phonology. They are discussed in the context of a model of functional architecture of reading in the two hemispheres in which orthography, phonology and semantics are fully interconnected in the LH, whereas in the RH, orthography and phonology are not directly connected, such that phonological processes are mediated by semantics.

Use Cases for Systems Engineering—An Approach and Empirical Evaluation

AbstractThis paper describes a use case driven approach for functional analysis/allocation and requirements flowdown. The approach utilizes use cases and use case realizations for functional architecture modeling, which in turn form the basis for design synthesis and requirements flowdown. We refer to this approach as the FAR (Functional Architecture by use case Realizations) approach. The FAR approach is currently applied in several large‐scale defense projects within BAE Systems Hägglunds AB. This paper also presents an empirical study where FAR is applied and evaluated in two large‐scale defense projects. Our results indicate that the FAR approach performs better than the previously used document based approach in the organization. © 2007, Wiley Periodicals, Inc. Syst Eng

제품가족의 기능적 구조 모델링

In mass customization, the focus is variety and customization through flexibility and quick responsiveness. Mass customizers seek to provide personalized, custom-designed products at low prices to give customers exactly what they want and to provide sufficient variety in products and services. The idea of the product family is the most adequate approach to realize mass customization. An understanding of customer needs using functional decomposition becomes necessary to enhance the performance of the product family. This paper focuses on functional architecture modeling based on customer need regarding sub-functions for the product family. A quantitative functional model captures product functionality and customer need. Based on customer need ratings and sub-function, a product-function matrix was created. Additionally, a product-product matrix was generated to provide a similarity index among product families. A case study for implementing the functional architecture modeling was performed on the single use cameras.

7.2.1 The FAR Approach – Functional Analysis/Allocation and Requirements Flowdown Using Use Case Realizations

AbstractThis paper describes a use case driven approach for functional analysis/allocation and requirements flowdown. The approach utilizes use cases and use case realizations for functional architecture modeling, which in turn form the basis for design synthesis and requirements flowdown. We refer to this approach as the FAR (Functional Architecture by use case Realizations) approach. The FAR approach is currently applied in several large‐scale defense projects within BAE Systems Hägglunds AB and the experience so far is quite positive. The approach is illustrated throughout the paper using the well known Automatic Teller Machine (ATM) example.

The functional architecture and interaction model of a generator of intelligent tutoring applications

This article presents the functional architecture and the interaction model of GENITOR, a generator of Intelligent Tutoring Systems (ITSs). The major design issues that arise during the functional design and development of an ITS-generator concern the provision of mechanisms capable of supporting the description of the teaching subject domain and the specification of pedagogical features of the ITSs that it produces. The system described in the article provides ready-to-use yet flexible solutions for the instructional features of the developed ITSs. In this way, authors can concentrate on the compilation, description, and design of training material that relates directly to their area of expertise. Interaction between GENITOR and authors has been designed using IOFG, an interaction model that supports the representation of multiple aspects of interaction, including data flow, control flow, and task decomposition. As a consequence of using this model, the tasks that make up the authoring process are visualized by a number of authoring tools that are grouped into three subsystems: the reusability subsystem, the authoring subsystem, and the execution subsystem. The functionality of these subsystems and the tools they contain are described, as well as interaction with the overall system. Finally, conclusions drawn from the development of two ITSs using the system are presented in order to validate the design.
