Problems of research of underground gas storage (UGS) wells are given. The analysis of the results of well research is carried out and the constant variability of filtration resistance coefficients of bottomhole zones of wells is substantiated. Studies of the influence of bottomhole pressures of wells on the calculated pressure at gas gathering stations (GGS) of underground storage facilities have been carried out. It was found that the calculated filtration resistance coefficients do not allow to calculate the pressures at the gas gathering stations of the underground storage plant with sufficient accuracy. The magnitude of the discrepancy between the measured and calculated pressures on the GGS varies depending on the flow rate and operating time of wells. It is established that the calculation of depression (repression) of pressure in the bottomhole zones of wells in non-stationary conditions of their operation gives underestimated results. © 2023 IEEE.

The changing needs of the enterprise require the manageability of its information system. Therefore, it is crucial to absorb these changes by orienting the design of the information system towards a modern architecture that decomposes the monolithic application into autonomous services. This paper proposes an enterprise architecture methodological framework to design the so-called microservice architecture known as MSA. Our approach is to describe the similarities between the MSA style of architecture and the service-oriented architecture known as SOA, the latter having a rich research literature focused on exploiting the methodology for designing services in a service architecture. The result of the comparative study indicates that the ideology for designing a SOA is identical as MSA which ultimately relies on decomposing applications into smaller components with a smaller and more manageable footprint. Thus, we conclude that it is preferable to use the adapted enterprise architecture methodology for SOA to design MSA.

Metamodel based approach to generate user interface mockup from UML class diagram

Interface and interaction design take up most of the times in software creation. Human computer Interaction (HCI) is mainly the best way to interact with a computer. During software development, class diagram is the only required step and process to design an information system according to UML notation. In addition, creating class diagram is a mandatory activity during the software creation process. The aim of this paper is to automatically generate the HCI mockup from class diagram to make easy and extremely fast software design. For example, the SEF (Schéma d’Enchaînement de Fenêtre), is an interface model allowing to create a new interface mockup. It offers more widgets to design the HCI. And MACAO (Méthode d’Analyse et de Conception d’Applications Orientées-objets) is one of the methods which helps computer scientist to easily create software. The model transformation is based on Model Driven Engineering (MDE). We use UML notation to design the class diagrams. We also adopt MDA architecture to create the model-based transformation process. Transformation rules are created using Atlas Transformation Language (ATL) to automatically generate a specific interface from the class diagram.

Automatic generation of Web service for the Praxeme software aspect from the ReLEL requirements model

Praxeme is an enterprise methodology that combines the two approaches SOA and MDA to build an information system. It is based on the ideology of separating the business concern into a homogeneous set called " aspect " to better control the usual complexity of a system. The instantiation of the ReLEL requirements model in the Praxeme methodology is an interesting approach to improve the quality of the software development process because it not only allows to specify the user requirements but also to represent the very precise conceptual level of the future system to be designed. Therefore, this article deals with the automatic generation of SOAP web services that represent the software aspect of the Praxeme methodology from the intentional aspect specified by the ReLEL requirements model. To achieve this, we proceeded in two steps, namely the proposal of the rules for deriving the Praxeme Logical Factory Model ( logical aspect ) into a Web Service Description Language model or WSDL ( software aspect ) classified as Model to Model Transformation ( M2M ) in the MDA approach and then the proposal of the rules for translating the WSDL model into a WSDL document known as Model to Text Translation ( M2T ). The result obtained from the approach proposed in this paper is a WSDL file which is an XML language allowing the complete description of a Web service. We used ATL for the implementation of the M2M approach transformation rules and then the Acceleo template engine for the translation of the M2T.

A graph G is a B_k-VPG graph if there exists an integer k such that each vertex corresponds to an orthogonal path in the plane with at most k bends. Two vertices $u$ and v in V(G) are adjacent if and only if the corresponding paths intersect.A graph G is said to be a B_k-EPG graph if there exists an integer k such that G has a string representation on a grid where each vertex corresponds to an orthogonal path (string) with at most $k$ bends. Two vertices u and v in V(G) are adjacent if and only if the corresponding paths share at least one grid *** consider the problems of finding optimal locating dominating sets, open locating dominating sets, and identifying codes of B_{k}-VPG (resp., B_{k}-EPG) graphs. We prove that the decision problems associated with these three notions are NP-complete in grid graphs (a subclass of unit B_{0}-VPG graphs). Secondly, we give an O(k^{2})-approximation algorithm for the dominating set problem on unit B_{k}-VPG graphs, improving the previous O(k^{4})-approximation algorithm of Chakraborty et al. \cite{dsj22}. Moreover, we show that the decision problem of locating dominating set is NP-complete on a subclass of B_{1}-EPG graphs, and we also show that the minimum locating dominating set problem is APX-hard on B_{1}-EPG graphs, ruling out the possibility of a PTAS unless P=***, we give a linear-time labeling algorithm for finding optimal locating dominating sets on the cactus graphs, which are a subclass of B_{1}-EPG graphs. © 2025, The Authors.

Chaos-based random bit generators are abundantly used in chaos-based encryption and security applications, as a fast, deterministic source of randomness, to perform actions like permutation and substitution. The chaotic map used as a source of randomness though may heavily affect the bit generator's statistical randomness, key space, and speed. Thus, any given bit generator may not be equally efficient for all the chaotic maps used as a seed. Motivated by this, the present work considers a bit generator that utilizes a common modulo-based hashing technique, and studies its performance under a plethora of different chaotic maps. For each map, the generator is evaluated with respect to randomness, key space, and operations per bit ratio. This analysis can serve as a guideline for random bit generator usage in future chaos-based encryption designs. © 2024 IEEE.

Aquaculture is actively evolving, requiring constant improvements in efficiency and new research. Regular weighing of experimental fish is one of the most important parts of research in the development of new fish farming methods and technologies. Conventional—manual—weighing is labor-intensive and causes high stress to the fish. An alternative way is automatic non-contact weighing using video cameras and different types of sensors. This paper presents an analytical review of non-contact weighing technologies. The review is based on an analysis of 43 scientific publications published in international journals. In reviewing the scientific publications, preference was given to methods that are most suitable for use in research laboratory aquariums and small tanks. The first part of the paper is devoted to justifying the relevance of the problem and analyzing the available reviews. The second part presents and compares different hardware installations for contactless weighing, such as single or multiple camera systems, sonar systems, different sensors, and combinations thereof. A qualitative comparison of hardware solutions is presented in terms of range, accuracy, applicability, and affordability. Due to different experimental conditions, no numerical data are given for method comparison. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
