The MESSIR Flexible Scientific Approach to Requirements Engineering

Among the software engineering development phases, requirements engineering is the one that has the most impact on project success or failure. To be executed in various contexts, there is an important need for flexibility and efficient tool support. A flexible requirements engineering method should include several levels allowing for more or less completeness and precision. Some project contexts would need a lightweight activity using structured natural language but still being guided and grounded partly on professional standards. Some more advanced projects would need more complete requirements documents and would benefit from a description language based on scientific notions allowing for better precision for specific system operations. Some business or safety critical systems would need an approach allowing for requirements simulation and verification. Requirements engineering education is an important objective to prepare future engineers to understand those requirements engineering needs and be prepared for practice in a professional setting. In the last five years, we have developed a requirements engineering method called Messir with a tool Excalibur and experiments in academia have been made to see how it was solving actual software engineering problems focusing first on requirements engineering education. Messir components represent in themselves some improvements w.r.t. the state of the art of the “standard” theories, methods and tools, mainly by introducing an improved requirements engineering process, language and verification support based on executable requirements specifications. Furthermore, the Messir approach solves also some actual problems related to software engineering education by offering a product line framework for setting up or improving courses in computer science curricula. The main result being to contribute to develop the software engineering capabilities of engineers and scientists that feed the job market in industry, research or education.

Guest Editorial Special Issue on Secure Data Analytics for Emerging Internet of Things

The rapid developments in hardware, software, and communication technologies have facilitated the spread of interconnected sensors, actuators, and heterogeneous devices such as single board computers, which collect and exchange a large amount of data to offer a new class of advanced services characterized by being available anywhere, at any time, and for anyone. This ecosystem is widely referred to as the Internet of Things (IoT). In the past years, the number of deployments both for sensor networks and the IoT grew significantly. This continuous and exponential growth is facilitated by investments and research activities originating from industry, academia, and governments while the penetration of these technologies is also driven by the high technology acceptance rates of both consumers and technologists across disciplines. Such networks collect, store, and exchange a large volume of heterogeneous data. Nevertheless, their rapid and widespread deployment, along with their participation in the provisioning of potentially critical services (e.g., safety applications, healthcare, and manufacturing) raise numerous issues related to the security, data analysis, and energy awareness of the performed operations and provided services.

Towards an Ontology for a Lightweight Support System for Production System Rough Planning

To shorten times-to-markets, also the planners of production systems have to be supported appropriately. For this, open, adaptable systems are needed which support continuous flows of information, e.g. by leveraging standard data formats – and, which are easy to use for planners without specific knowledge about software development or ontology engineering. This paper introduces a support system for production system rough planning, especially for, but not limited to, assembly systems, which consists of two main components: a standard-based ontology as explicitly formulated external data model and a relatively universal software system working on the ontology. Thereby, focus of this contribution is mainly on the ontology, so on manufacturing modeling.

AN OVERVIEW OF USING GRAPH THEORY IN SOFTWARE SYSTEM DEVELOPMENT AND MAINTENANCE

Graph theory has gained considerable popularity in many areas of application due to its versatility, including ease of modeling and visualization. In general, a graph can represent an arbitrary model of real-world objects and the relationships between them, which allows applying any known algorithms to it and subject it to other types of further analysis. The theoretical foundations of graphs are also widely used in the field of operations research. For example, the travelling salesman problem, finding the minimum spanning tree of a weighted graph, finding the shortest path between two vertices etc. The purpose of this work is to analyze the practical applications of graph theory, both in the process of software development and for software development in general, as well as in the subsequent maintenance and support of software systems. In addition to using the theoretical foundations of graphs in other branches of science, graph theory has also found wide application in solving many practical problems in different areas of human life, such as chemistry, sociology, logistics, biology, economics, technology and so on. Similarly, in software development, graph theory has taken its rightful place. Many kinds of problems are solved with its help, both in the process of software engineering and for the development of software engineering itself. The analysis of the graph theory application opportunities for software development and maintenance has shown that at most stages of the software development cycle, graphs are used only for modeling and visualization of various kinds of information, but there is almost no automated algorithmic analysis of the obtained models. This may indicate a promising direction for discovering additional opportunities of graph theory usage in the software development processes.

STATISTICAL SOFTWARE R IN CORPUS-DRIVEN RESEARCH AND MACHINE LEARNING

The rapid development of computer software and network technologies has facilitated the intensive application of specialized statistical software not only in the traditional information technology spheres (i.e., statistics, engineering, artificial intelligence) but also in linguistics. The statistical software R is one of the most popular analytical tools for statistical processing a huge array of digitalized language data, especially in quantitative corpus linguistic studies of Western Europe and North America. This article discusses the functionality of the software package R, focusing on its advantages in performing complex statistical analyses of linguistic data in corpus-driven studies and creating linguistic classifiers in machine learning. With this in mind, a three-stage strategy of computer-statistical analysis of linguistic corpus data is elaborated: 1) data processing and preparing to be subjected to a statistical procedure, 2) utilizing statistical hypothesis testing methods (MANOVA, ANOVA) and the Tukey post-hoc test, and 3) developing a model of a linguistic classifier and analyzing its effectiveness. The strategy is implemented on 11 000 tokens of English detached nonfinite constructions with an explicit subject extracted from the BNC-BYU corpus. The statistical analysis indicates significant differences in the realization of the factors of the parameter “Part of speech of the subject”. The analyzed linguistic data are employed to build a machine model for the classification of the given constructions. Particular attention is devoted to the methodological perspectives of interdisciplinary research in the fields of linguistics and computer studies. The potential application of the elaborated case study in training undergraduate, master, and postgraduate students of Applied Linguistics is indicated. The article provides all the statistical data and codes written in the R script with comprehensive descriptions and explanations. The concluding part of the article summarizes the obtained results and highlights the issues for further research connected with the popularization of the statistical software complex R and raising the awareness of specialists in this statistical analysis system.

Design and Implementation of Web Multimedia Teaching Evaluation System Based on Artificial Intelligence and jQuery

It is an important reflection of modern education and an overwhelming way to strengthen the quality of teaching. In the current environment, the traditional multimedia classroom management model can no longer adapt to the current rapidly developing network environment. How to manage more and more campus multimedia classrooms is an urgent problem to be solved. The informatization construction and application of multimedia classrooms is the key to the realization of educational informatization. The traditional multimedia classroom management model has not been able to adapt to the rapidly developing network environment, which is mainly manifested in the following aspects: electronic education management personnel cannot discover and process teaching in a timely manner. Equipment failure has not formed a set of standard troubleshooting procedures and cannot accurately record the status, use time, and maintenance records of various teaching pieces of equipment. This will not only affect the teaching quality of colleges and universities but also slow down the process of education informatization. This paper develops a web-based multimedia teaching equipment management system based on artificial intelligence and jQuery, which realizes the centralized control and management of various multimedia teaching equipment. According to the actual needs of multimedia teaching, this paper follows the design and development of software engineering, using artificial intelligence, jQuery, Ajax, and Spring MVC technology to design and develop a web-based multimedia teaching equipment management system. On the basis of realizing the centralized control and management of multiple multimedia teaching equipment, it can also track and record the use status and maintenance content of the multimedia teaching equipment to form an information knowledge base of the multimedia equipment, which is convenient for later maintenance and management. Through the use of this system, management can be systematized, standardized, and automated, reducing the tedious workload of management and maintenance personnel. It can speed up the information management process of multimedia teaching equipment and improve the work efficiency of related managers. A course can be studied online, and an online teaching system has been developed. According to our survey on Mandarin online course training in Northwest China (N = 343), we found that 81.6% of samples are satisfied with the Mandarin online training courses; 21.6% think that they have learned new teaching methods/teaching concepts from the teacher through the Mandarin training; 36.2% think that they have learned the theoretical knowledge of Mandarin through the Mandarin training. Gender, age, ethnicity, and learning experience are related to the difficulty of learning Mandarin online courses. Therefore, we can satisfy learners of different ages, learning foundations, and cultural backgrounds by designing different online course patterns, so as to enhance the high-quality promotion of Mandarin.

Evaluating the role of endometrial colour Doppler dynamic tissue perfusion measurements in in vitro fertilisation success

The role of uterine receptivity and endometrial perfusion in in vitro fertilisation (IVF) remains unclear. In our prospective pilot study, we used a new dynamic tissue perfusion measurement method to evaluate this relationship in humans. A standard ovulation induction and embryo transfer method were applied to all the volunteers. On the day of embryo transfer, dynamic images of the uterus were recorded using colour Doppler ultrasound, and these images were uploaded onto PixelFlux Chameleon Software (GmbH, Münster, Germany). After determining the region of interest (ROI), the average velocity, intensity, and area values for all coloured pixels in the ROI, the tissue resistance index (RI) and the tissue pulsatility index were calculated. Endometrial thickness, morphology and dynamic endometrial perfusion parameters were compared between the clinically pregnant and non-pregnant groups. Endometrial thickness, morphology values and endometrial dynamic tissue perfusion measurements were similar between the groups. This study compared perfusion parameters between clinically pregnant and non-pregnant patients by accurately calculating endometrial tissue perfusion using standard software to establish its relationship with implantation success in IVF treatment. IMPACT STATEMENT What is already known about this subject? The relationship between IVF success, endometrial receptivity and perfusion is known. Clear valuations of endometrial receptivity require an endometrial biopsy which may cause endometrial damage to the actual IVF cycle. This problem has led researchers to conduct non-interventional studies. Studies have revealed the value of endometrial thickness, pattern and Doppler examination of endometrial uterine arteries in predicting the success of IVF treatment. What do the results of this study add? This prospective pilot study is the first one to use this programme in humans to evaluate uterine receptivity in IVF. Successful results can be obtained by using computer programmes in tissues where perfusion parameters cannot be measured using traditional colour Doppler ultrasonography. Revealing the relationship between tissue perfusion and IVF success will be more effective and accurate with the development of software technologies. What are the implications of these findings for clinical practice and/or further research? To increase the success of IVF treatment, current and new technological developments, as well as imaging methods should continue to be tested.
