Abstract

Several approaches and tools have been proposed to facilitate the automatic generation of Unified Modeling Language (UML) class diagrams from natural language specifications, based on advances in Natural Language Processing (NLP). However, these tools suffer from difficulties due to the inherent imprecision and ambiguity commonly found in natural language expressions. In this article, we present an overview and a study of approaches and tools designed to extract UML diagrams from textual requirements using NLP and computational linguistics techniques. Furthermore, we introduce approaches employing deep learning techniques. Next, we provide a descriptive study and comparative analysis of the limitations and contributions of these automatic and semiautomatic tools, as well as solutions for improving the existing state of the art.

Abstract

The agricultural sector faces serious challenges related to climate change. These changes have the potential to reduce yields and food security, highlighting the importance of understanding and managing temperature dynamics. This work is the result of development a thermodynamic model that investigates the dynamics of temperature balance through heat energy transfer. A scheme of rheological heat exchange of an object with an insulated surface and graphs of irreversible rheological transformations are proposed. The main equation of heat exchange with a chemical reaction is given and the equation of the speed of heat energy transfer along the length of the object is derived. Further development of physical-mathematical models of the transformation of thermal energy into a set of states of the object is proposed. The experimental results fully correlate with the heat transfer equation. Samples with tomato seeds were irradiated with a photon irradiator with wavelengths of blue 450 nm, green 550 nm, red 650 nm with an exposure of 12/24 h. As a result, 90 % under the influence of the red spectrum of the photon irradiator for 24 h, which is 24 % more than the control sample. This will make it possible to assess the general temperature regime of agricultural objects and optimize the heating process. This study reveals the essence of temperature regulation at agricultural facilities using a thermodynamic model, which not only takes into account heat exchange, but also includes the influence of chemical reactions. The proposed thermodynamic model and associated equations provide a foundation for future research and practical applications that will ultimately benefit the agricultural industry, global food production.

Abstract

Class diagram is an important model in object-oriented software development. A class diagram specifies the structure of a system with the system's classes, classes' attributes and methods, and relations among classes. Sometimes class diagrams should be modified in accordance with requirements changes or correction of errors. In such a modification, careless mistakes may lead to include another error in the diagram. In this paper, we propose a method of visualization of the difference between original class diagram and modified one by emphasizing the difference in order to avoid newly produced errors. We illustrate our method with examples. [ABSTRACT FROM AUTHOR]

Abstract

Designing a system is an important step in the software development process. A use case diagram (UCD) and a class diagram (CD) are the most used diagrams in designing a system. This case study aims to explore the implementation of an event-based approach using the event table (ET) to design the Outcome-based Education Curriculum System (OBECS). In generating a UCD of OBECS, the event-based approach involves three processes: (1) identifying actors and the relationship between actors; (2) identifying use cases and the relationships of the use cases; and (3) generating UCD. Meanwhile, there are four processes in the event-based approach which can be used to generate a CD of OBECS namely: (1) identifying the classes for each event or action using the ET;(2) identifying the relationships between sources and objects; (3) identifying the class’ attributes and methods; and (4) integrating all classes. Our study proposes a clear and simple concept to generate a UCD and CD in designing a system. It is expected that the result of the current study could help a software designer in modelling the system from the system requirement.

Abstract

Due to the lack of available information in the early stages of project creation, early estimation of the project size is a difficult task. The information appears more detailed and clear as we progress in the stages of building the software. The aim of the research is to design and implement a model to estimate the size of the program in the two phases of analysis and design separately, and in the phases of analysis and design together using four measures of the class diagram, which are "number of classes", "number of features", "number of operations" and "number of relationships".

38. Fractional weightage based objective function to a hybrid optimization algorithm for model transformation.

Author

Jadhav, Pramod P. and Joshi, Shashank D.

Abstract

Model transformation (MT) contributes a major role in the model-driven engineering (MDE), which are used to transfer the models among various languages to refactor and simulate the models or to obtain the useful codes from the models. Thus, the need for MT in MDE is very important, but the practical methods are not suitable for the detection of errors in transformations. This paper proposes an advanced algorithm, called fractional whale optimization integrated adaptive dragonfly (F-WOADF) algorithm to perform the MT from the class diagram (CLD) to relational schema (RS) model. The proposed algorithm modifies the adaptive dragonfly (ADF) algorithm with the concept of whale optimization algorithm (WOA) using the fractional theory. The UML CLD is transformed into the RS model using the optimal blocks that are selected with the use of the proposed algorithm. The performance of the F-WOADF method is evaluated using automatic correctness (AC), and fitness measure. The proposed method produces the maximum AC of 0.8583 and the maximum fitness measure of 0.8984 that indicates the effectiveness of the proposed method. [ABSTRACT FROM AUTHOR]

Abstract

In the modern database environment, new non-traditional database types appear that are Not SQL database (NoSQL). This NoSQL database does not rely on the principles of the relational database. Couchdb is one of the NoSQL Document-Oriented databases, in Couchdb the basic element was a document. All types of databases have the same conceptual data model and it was deferent in the logical and physical model, this mean UML class diagram can be used in the NoSQL design at a conceptual level, that is, it can be used to design a Couchdb database. In this research, we suggest a method to model and implement the conceptual level of the Couchdb database from the UML class diagram in using simple way depending on the association types. Depending on the types of relationships between classes, we can have more than one database model to choose from and find the most suitable for the system to be designed. A medical clinic database was proposed to implement the transfer steps according to the proposed method. Three database models were designed and implemented to study the suitability of the proposed transfer method.

Abstract

Early software size estimation is a challenging task since limited information is available at the time of project inception. Additional information, however, is gradually added as development progresses. The goal of this research is to quantitatively capture the impact on early software size estimation of this additional information introduced especially when transitioning from the analysis phase to the design phase by comparing the analysis class diagram (ACD) and the design class diagram (DCD). We introduce a new class of metrics called analysis-to-design adjustment factors (ADAFs) to accomplish this goal. ADAFs are calculated for four different class diagram metrics – number of classes (NOC), number of attributes (NOA), number of methods (NOM), and number of relationships (NOR) – used in different class diagram-based software size estimation models. We use practical, theoretical, and empirical validation methods to evaluate the applicability of these ADAFs. To assess the utility of these ADAFs in early software size estimation, we compare the accuracy of existing early software size estimation models before and after the application of ADAFs. Results indicate a marked improvement in the accuracy of these models after the application of ADAFs. Furthermore, regression-based models employing problem domain metrics have also been built to predict these ADAFs. All of these models are statistically significant (p-values < 0.05) with R2 values between 0.42 and 0.88.

Abstract

Regression test selection (RTS) approaches reduce the cost of regression testing of evolving software systems. Existing RTS approaches based on UML models use behavioral diagrams or a combination of structural and behavioral diagrams. However, in practice, behavioral diagrams are incomplete or not used. In previous work, we proposed a fuzzy logic based RTS approach called FLiRTS that uses UML sequence and activity diagrams. In this work, we introduce FLiRTS 2, which drops the need for behavioral diagrams and relies on system models that only use UML class diagrams, which are the most widely used UML diagrams in practice. FLiRTS 2 addresses the unavailability of behavioral diagrams by classifying test cases using fuzzy logic after analyzing the information commonly provided in class diagrams. We evaluated FLiRTS 2 on UML class diagrams extracted from 3331 revisions of 13 open-source software systems, and compared the results with those of code-based dynamic (Ekstazi) and static (STARTS) RTS approaches. The average test suite reduction using FLiRTS 2 was 82.06%. The average safety violations of FLiRTS 2 with respect to Ekstazi and STARTS were 18.88% and 16.53%, respectively. FLiRTS 2 selected on average about 82% of the test cases that were selected by Ekstazi and STARTS. The average precision violations of FLiRTS 2 with respect to Ekstazi and STARTS were 13.27% and 9.01%, respectively. The average mutation score of the full test suites was 18.90%; the standard deviation of the reduced test suites from the average deviation of the mutation score for each subject was 1.78% for FLiRTS 2, 1.11% for Ekstazi, and 1.43% for STARTS. Our experiment demonstrated that the performance of FLiRTS 2 is close to the state-of-art tools for code-based RTS but requires less information and performs the selection in less time.

Abstract

The article presents an approach aimed at automatically deriving the initial conceptual database model from a set of business process models. The approach proposes the incremental synthesis of the target model by iteratively composing the partial conceptual database models that are derived from the models contained in the source set. The approach is implemented by the AMADEOS tool, which is the first online web-based tool enabling the automatic derivation of the conceptual database model from a set of business process models. The experimental evaluation proves that the implemented approach enables effective automatic derivation of the initial conceptual database model. [ABSTRACT FROM AUTHOR]

Abstract

At first sight, managing order management activities in a restaurant may seem simple, but in reality, things are not like that at all. All decisions made can have a major impact on how the business will evolve over time. For an efficient and corresponding administration is required the existence of a management information system for order management received from restaurant customers, but also of all specific collateral data: locations, meals, waiters or menus. Computer systems for managing these types of activities have practically influenced the way a restaurant can be administered today, fact for which they are currently used on a fairly large scale. Thus, the purpose of this paper is to present how to design an application for order management at a restaurant level, application that can be useful to both restaurant employees and its customers. In this context, the paper presents two UML diagrams (Unified Modelling Language) which describe both the processing of the future computer system (UseCase Diagram) as well as its conceptual structure (Class Diagram) from the perspective of the data that this computer system will manage.

Abstract

One current trend for providing delay-tolerant communications under highly-dynamic routing conditions is to form ad hoc OppNets with the exploitation of smart mobile devices carried by people. Modern smartphones hide a great potential for emergency monitoring and management: they are truly pervasive, they can establish peer-to-peer wireless links using short-range communication technologies, thus guaranteeing coverage even when fixed infrastructures are unavailable, they can define the location with high accuracy through several embedded sensors and send messages without global connectivity. The paper examines the possibility of creating a mobile ad hoc network based on smartphones running the iOS 10 operating system and higher in emergencies, providing that each smartphone is equipped with transmitters for working with Wi-Fi, Bluetooth, GPS, and GLONASS interfaces. To solve this problem, a transparent automatic system for selecting alternative communication channels is organized with the possibility of localizing neighboring reachable nodes to broadcast coordinates to them with further reporting the available information to the appropriate special (rescue) services. The article describes the mechanism of nodes' interaction based on the Multipeer Connectivity framework. With this framework and the Bonjour software module, giving a protocol for automatic detection of services, an emergency informing system has been developed. This system provides the ability to deploy ad hoc network without directly accessing the global network of each of its participants, to localize the emergency zone, and to send an SOS- message to all connected peers.

Abstract

The assurance of quality and reliability of process models and workflows is essential for model driven software development. There are numerous ways to achieve these objectives. One is model checking through which it can be verified that a model satisfies specific logical rules. The model to be checked is usually given as finite state machine. Rules have to be specified at the level required by the model checker. In this work, we develop a model for validating the DNA profiling through finite state.. This enables the research/business process professionals to use model checking techniques and to produce higher quality research/business models for subsequent software development. The approach is demonstrated by validating event-driven process chains. [ABSTRACT FROM AUTHOR]
