Business processes are structured sequences of activities, events, and other elements designed to fulfill customer needs in services or goods. Business process management is an approach used to combine information technology and management fields to develop, maintain, and improve organizational workflows. Business process modeling is a key technique employed for graphical description and analysis of organizational activities, it helps to understand, capture, analyze, and improve enterprise business processes. Thus, the quality of designed models should be carefully controlled to ensure timely business process modeling errors detection and prevention prior to they turn into errors leading to extra costs or other negative impacts on an organization. Business Process Model and Notation (BPMN) is the de-facto standard of workflow description in recent years, providing a well-structured notation to describe complex organizational activities. Hence, in this study we consider the complexity of BPMN models as one of the main quality attributes formulated in the business process modeling field. The task of complexity evaluation of BPMN models is addressed, the key complexity metrics of BPMN models are considered, a prediction machine learning model is proposed using linear regression model, the respective software tool is designed, implemented and verified. Obtained experimental results are analyzed and discussed. ©2024 IEEE.

The high complexity of business process models may negatively impact their quality and usability, and cause errors, costs, or even more serious damage to critical business processes when inefficient models are used. Therefore, in this study, we propose the fuzzy logic-based software tool to assess the complexity of business process models. This software tool uses the fuzzy inference system, in which rules are inferred from the existing business process model complexity metrics and their thresholds. However, the use of the fuzzy logic-based approach outperforms the existing approach based on crisp metric values and the weighted sum model by 30%, when the obtained results are compared to the expert judgment results. Fuzzy inference rules are similar to human reasoning and assume uncertain or borderline metric values by improving assessment results. © 2023 IEEE.

The study presents a methodology for automatically creating an annotated dataset for further use in training neural networks. The method is based on the Crisp-DM framework and consists of 6 stages: business understanding, data understanding, data preparation, modeling, evaluation, deployment, which has been modified due to the specifics of computer vision tasks. As a modeling method, the k-means method is proposed, which is applied to the normalized area and average color data of a given object. The approach is tested for creating an annotated dataset for recognizing and localizing cells of different types in blood smear images. The output is a dataframe with the columns file_name, xmin, ymin, xmax, ymax, type, area, which represent the file name, the coordinates of the upper left and lower right points of the bounding boxes, the cell type, and its area. Using these parameters and image processing libraries it is easy to add bounding boxes to the original images. The resulting annotated dataset is analyzed. Metrics were calculated and a loss matrix was constructed. All calculations were performed using the Python programming language and the Pandas, numpy, openCV, and matplotlib libraries. ©2024 IEEE.

This paper discusses the use of a method for collecting a high dynamic range image from intermediate images with contrast enhancement in different parts of the amplitude characteristic. Simultaneously, for each subrange, the chromaticity coordinates of a colour space with a large coverage are recalculated. In the new color space, the dots shift slightly, but the nature of the shift depends on the color tone. © 2024 IEEE.

Over the past twelve years, search engine optimization has become a classic technology for product promotion. Its tools have also become classics, such as Google AdWords advertising, HTML code optimization and building the semantic core of a WEB resource. However, recently they no longer give significant results, and their efficiency drops. We completed several WEB projects in 2020–2021, the results of which show a catastrophic drop in the efficiency of classic SEO tools by at least 50%. The main reason for this is that the online market is constantly changing due to competition. In our study, we propose to look for ways to improve efficiency based on the reengineering of existing tools. To implement the reengineering procedure, it is necessary to evaluate the effectiveness of existing SEO tools. Therefore, in this paper, we focused on the problem of evaluating the effectiveness of the semantic kernel of digital content as the most common approach in SEO. It is based on the method of analyzing the current situation and its automatic evaluation. By the situation, we mean a set of WEB documents that contain a semantic kernel. Therefore, the evaluation of the efficiency of the kernel must be performed both from the point of view of the document and from the point of view of the keyword. Further, such an assessment should also include a measure of the quality of the semantic kernel from the position of the search server. Such a server offers two evaluation tools. The first is WEB statistics, that is, how many visits this kernel attracted. Another way is the structure of the kernel itself, that is, what keywords are included in its composition. And the third component of the assessment is the budget or financial resources that need to be spent on the synthesis and implementation of the kernel on the Internet. Based on the results of this modeling, the article shows a real example (WEB project in the American online services market), in which this evaluation procedure was

Over the past ten years, we have been conducting research in the field of search engine optimization. More than 30 WEB projects of varying complexity were completed (online services, medicine, household goods, jewelry, lumber, auto parts). The results of these projects show two key problems. The first problem is that classic search engine optimization approaches such as Google AdWords advertising, HTML code optimization and building the semantic kernel of a WEB resource no longer provide significant results in a given period of time. The second problem is that there are no exact metrics that show when and with what budget the desired result can be achieved. The main reason for this is that these classic search engine optimization techniques are static, and the online market is constantly changing due to competition. Therefore, we have proposed a new information technology – virtual promotion of a product. Its skeleton is a virtual promotion map. This map is created based on the concept of a cognitive map. That is, it is a method of analyzing the current situation and automatically making a decision. By introducing a virtual promotion map into the project, we create a new decision-making mechanism for the implementation of a WEB search engine optimization project. The virtual promotion map includes two levels. The first one describes the Internet nodes where the semantic core of the e-content of our WEB project will be placed. The second level describes the cost of placing the semantic kernel. The second level is a mathematical programming problem, the solution of which gives us an answer on which nodes and for how long it is necessary to place the semantic core in order to obtain the desired result. The article shows a real example (WEB project in the American market of online services), in which a virtual promotion map was applied. Its application gave a tenfold increase in the main key performance indicator (traffic) over a given period of time (9 months) and a gi

A Structured Basis to Determine Equivalent Dielectric Properties of Homogeneous Phantom Liquid Representing Multilayer Biological Tissues for SAR Measurement

Progress In Electromagnetics Research B 2024年 108卷 1-16页

In today’s era of wireless communication, interaction of electromagnetic energy and living biological systems is unavoidable — both in far field and in near field of the radiating antenna. Consequent basic safety limits on radiation levels are enforced through Specific Absorption Rate (SAR) limits. Practical measurement and validation of these SAR values require the deployment of phantom models containing tissue equivalent dielectric liquids — these liquids are conventionally single layer and homogeneous in nature. However, structured basis to formulate these custom made homogeneous phantom liquids representing arbitrary combinations of stacked tissue layers has not been properly reported in literature. To address the issue, this paper develops and illustrates a novel structured technique to define equivalent permittivity and loss tangent of homogeneous phantom liquid representing arbitrary combinations of stacked tissue layers — both in far field and in near field exposure scenarios. Electric field distribution and later on point SAR distribution inside different tissue layers have been attempted to replicate as closely as possible using equivalent homogeneous phantom liquid with properly tuned permittivity and loss tangent values. The fitting procedure involves minimization of the absolute/normalized maximum difference (of electric field and point SAR) between the original multilayer tissue and the modelled single layer homogeneous equivalent. This generalized technique is applied to two distinct multilayer (four layers are considered) biological models at 2.45 GHz where one is composed of four layers of equal thicknesses while the other one has four layers with unequal thicknesses. Moreover, the proposed technique has been tested and validated in the two abovementioned multilayer biological models for both far field (plane wave irradiation) and near field (in close proximity to antenna) exposure scenarios. This technique is quite successful in achieving equivalen

The work deals with issues that are relevant for developers of websites and web applications to support users with certain disabilities who access the Internet via desktop computers or laptops using screen reader NVDA. The core users of NVDA are blind people. The effectiveness of using the application depends on the quality and completeness of the description of the web page tags. The purpose of the research is to ensure the appropriate level of accessibility of web pages that will be used by blind users using NVDA. Formalized rules for analyzing structure of webpages in the form of predicates calculus have formed. The proposed technology for developing webpages and web applications has been presented in the form of BPMN business process diagrams. Approach for automated detection of problematic tags in the structure of webpages has considered. Several webpages with identical design and different web-structure have been researched for checking accessibility requirements for blind people. The results of webpage accessibility estimation and the corresponding screenshots that visualize problematic situations in the work of blind users with a webpage have presented. © 2023 IEEE.

The article explores a technique for improving the efficiency of cargo control by an unmanned aerial vehicle (UAV) by creating an automatic load stabilizer in free fall. An assessment is given of a study on improving the efficiency of cargo UAV control by 3D simulation of cargo drop and fall. The steps of measuring the UAV cargo deviation from a fixed point using an Inertial Measurement Unit (IMU) built using micro electromechanical systems (MEMS) are investigated. To check the adequacy of the proposed models, an algorithmic software tool was developed to simulate the accuracy of cargo drop from UAV. As a result of the experiments, the optimal coefficients for the Proportional-Integral-Derivative (PID) controllers were determined, the error of the inertial measurement system was determined, equal to 0.95% with a displacement of 30 cm. The conclusions will be useful to developers of cargo UAVs. © 2023 IEEE.
