Around a third of the total population of Europe suffers from mental disorders. The use of electroencephalography (EEG) together with Machine Learning (ML) algorithms to diagnose mental disorders has recently been shown to be a prominent research area, as exposed by several reviews focused on the field. Nevertheless, previous to the application of ML algorithms, EEG data should be correctly preprocessed and prepared via Feature Engineering (FE). In fact, the choice of FE techniques can make the difference between an unusable ML model and a simple, effective model. In other words, it can be said that FE is crucial, especially when using complex, non-stationary data such as EEG. To this aim, in this paper we present a Systematic Mapping Study (SMS) focused on FE from EEG data used to identify mental disorders. Our SMS covers more than 900 papers, making it one of the most comprehensive to date, to the best of our knowledge. We gathered the mental disorder addressed, all the FE techniques used, and the Artificial Intelligence (AI) algorithm applied for classification from each paper. Our main contributions are: (i) we offer a starting point for new researchers on these topics, (ii) we extract the most used FE techniques to classify mental disorders, (iii) we show several graphical distributions of all used techniques, and (iv) we provide critical conclusions for detecting mental disorders. To provide a better overview of existing techniques, the FE process is divided into three parts: (i) signal transformation, (ii) feature extraction, and (iii) feature selection. Moreover, we classify and analyze the distribution of existing papers according to the mental disorder they treat, the FE processes used, and the ML techniques applied. As a result, we provide a valuable reference for the scientific community to identify which techniques have been proven and tested and where the gaps are located in the current state of the art.

The number of references per paper, perhaps the best single index of a journal's scholarliness, has been studied in different disciplines and periods. In this paper we present a four decade study of eight engineering journals. A data set of over 70,000 references was generated after automatic data gathering and manual inspection for errors. Results show a significant increase in the number of references per paper, the average rises from 8 in 1972 to 25 in 2013. This growth presents an acceleration around the year 2000, consistent with a much easier access to search engines and documents produced by the generalization of the Internet. [ABSTRACT FROM AUTHOR]

An adaptive system is able to adapt at runtime to dynamically changing environments and to new requirements. Adaptive systems can be single adaptive entities or collective ones that consist of several collaborating entities. Rigorous engineering requires appropriate methods and tools that help guaranteeing that an adaptive system lives up to its intended purpose. This paper introduces the special section on "Rigorous Engineering of Collective Adaptive Systems." It presents the 11 contributions of the section categorizing them into five distinct research lines: correctness by design and synthesis, computing with bio-inspired communication, new system models, machine learning, and programming and analyzing ensembles.

This editorial article discusses recent findings in the optimization and engineering for sustainable development. The current Special Issue (SI) of the Optimization and Engineering journal stems from the 2022 Sustainable Development of Energy, Water and Environment Systems Conferences. These events included the 5th South East European, 3rd Latin American, and 17th SDEWES Conferences. Being selected from conference presentations, the papers in SI represent the main topics in optimization approaches that integrate various life-supporting systems discussed during these three events. After careful selection, the current SI accepted ten excellent papers summarized here. These contributions use differentiated modeling approaches and supporting tools, such as P-graph and network-flow modeling, computational fluid dynamics, pinch analysis (PA), and the Geographic Information System. The range of optimization methods includes mixed-integer linear and mixed-integer nonlinear programming (MILP and MINLP), dynamic programming, stochastic optimization, and PA and P-graph extensions.

This paper was triggered by concerns about the methodological soundness of many RE papers. We present a conceptual framework that distinguishes design papers from research papers, and show that in this framework, what is called a research paper in RE is often a design paper. We then present and motivate two lists of evaluation criteria, one for research papers and one for design papers. We apply both of these lists to two samples drawn from the set of all submissions to the RE’03 conference. Analysis of these two samples shows that most submissions of the RE’03 conference are design papers, not research papers, and that most design papers present a solution to a problem but neither validate this solution nor investigate the problems that can be solved by this solution. We conclude with a discussion of the soundness of our results and of the possible impact on RE research and practice. [ABSTRACT FROM AUTHOR]

His main interests include resource optimization technique, adaptive resource provisioning, multi-objective optimization, computational intelligence, incomplete information processing, cloud computing, and security. The evaluation showed that these apps had an acceptable score on the System Usability Scale (SUS). The paper "Influence of Belbin's Role Theory on Database Design: Experimenting with Software Engineering Students" explores the benefits of using Belbin's role theory of team and individual related tasks in the software development process, particularly for Database Design (DB) Design. The authors argued that the usability evaluation described in this work can serve as a reference for developers seeking to improve learning monitoring and personalization services in software applications.

Origami, an ancient form of papercraft, provides a way to develop functional structures for engineering applications. In this paper, we report an approach to design and manufacture a stretchable circuit board (SCB) with origami structures. The benefits of developable, flat-foldable, and rigid-foldable origami-based structures as SCBs are discussed, and a representative structure, Miura fold (or Miura-ori), is chosen to be investigated. Under the constraints induced by the mounted components' dimensions, the Miura-ori structures for specific applications can be defined. We propose three methods for better fabrication, including direct folding, stiffness modification, and kirigami enhancement, to improve a planar sheet's foldability. A wearable ECG (electrocardiogram) system based on MO-SCB (Miura-ori enabled SCB) technology is built, and the stretchable portion is made of commercial FPCBs (flexible printed circuit board), providing desired stretchability and reliability. The proposed technology routine is compatible with industrial production and may pave the application of stretchable electronics. [ABSTRACT FROM AUTHOR]

Experimental Philosophy (X-Phi) is now a fully-fledged methodological project with applications in almost all areas of analytic philosophy, including, as of recently, aesthetics. Another methodological project which has been attracting attention in the last few years is conceptual engineering (CE). Its areas of implementation are now diverse, but as was the case initially with experimental philosophy, aesthetics has unfortunately been left out (or perhaps aestheticians have failed to pay attention to CE) until now. In this paper, I argue that if conceptual engineers are interested in expanding their project to the field of aesthetics, which would greatly benefit the field, then they should rely on the existing experimental work of aestheticians. Experimental philosophers have only recently started to join forces with conceptual engineers in various fields, as well as to explore the methodological implications of such an alliance. This paper goes a step further by not only arguing that CE has potential in aesthetics, but that the way to realize this potential is to piggyback, so to speak, on the work of experimental aestheticians. In other words, instead of building a CE project in aesthetics from the ground up, this paper describes the support that CE can and should derive from current experimental aesthetics, thereby making the former's development more efficiently realizable. Furthermore, I argue that doing so would also be beneficial to experimental aesthetics. Currently, the integration of X-Phi to the wider field of aesthetics is losing ground because certain objections—notably, the objection that X-Phi cannot be of relevance to normative questions—have not been properly refuted. By pairing up with a normative programme like CE, though, experimental aestheticians should finally be able to put these objections to rest. [ABSTRACT FROM AUTHOR]

The quality of requirements is typically considered as an important factor for the quality of the end product. For traditional up-front requirements specifications, a number of standards have been defined on what constitutes good quality : Requirements should be complete, unambiguous, specific, time-bounded, consistent, etc. For agile requirements specifications, no new standards have been defined yet, and it is not clear yet whether traditional quality criteria still apply. To investigate what quality criteria for assessing the correctness of written agile requirements exist, we have conducted a systematic literature review. The review resulted in a list of 16 selected papers on this topic. These selected papers describe 28 different quality criteria for agile requirements specifications. We categorize and analyze these criteria and compare them with those from traditional requirements engineering. We discuss findings from the 16 papers in the form of recommendations for practitioners on quality assessment of agile requirements. At the same time, we indicate the open points in the form of a research agenda for researchers working on this topic. [ABSTRACT FROM AUTHOR]

The German engineer H.A. Janssen gave one of the first accounts of the often peculiar behavior of granular material in a paper published in German in 1895. From simple experiments with corn he inferred the saturation of pressure with height in a granular system. Subsequently, Janssen derived the equivalent of the barometric formula for granular material from the main assumption that the walls carry part of the weight. The following is a translation of this article. The wording is chosen as close as possible to the original. While drawings are copied from the original, figures displaying data are redone for better readability. The translation is complemented by some bibliographical notes and an assessment of earlier work, wherein Hagen predicted the saturation of pressure with depth in 1852, and Huber-Burnand demonstrated that saturation qualitatively as early as in 1829. We conclude with a brief discussion of more recent developments resting on Janssen's work. [ABSTRACT FROM AUTHOR]

Nanotechnology is a research field that has potential to drive the progress of mankind for the next few decades. Its application is found in every discipline, ranging from material science to space communication. Owing to its potential for ubiquity, and capability of replacing many general purpose technologies, co-existence of several paradigms are expected in nanotechnology. Flow Vergence (FV) gradient has been recently introduced as a metric to mine the network of scientific literature for detecting the paradigm shifts. In this paper, we have performed citation network analysis of scientific publications in nanotechnology from research area 'engineering' for identification of paradigms related to the same. Flow vergence gradient revealed 18 subnetworks that deal with 25 likely pivots of paradigm shifts. Major paradigm shifts can be found in the field of targeted drug delivery. Nanonetworks, a crossover of IT, BT and nanotechnology is the another interesting paradigm shift identified. An extended subnetwork analysis has been conducted to identify the competing or complementary nature of the emerging paradigms in the subnetworks. A framework for this has also been introduced. This analysis revealed that most of the paradigms in the targeted delivery are competing paradigms. Complementary paradigms are also identified in nano electronics and targeted drug delivery. Policy implications from this identification for various target groups are also discussed. [ABSTRACT FROM AUTHOR]

Complexity is often regarded as a "problem" to solve. Instead of attempting to solve complexity, we follow systems engineering practices and switch back to the problem domain, where a major obstacle is the impossibility to universally define complexity. As a workaround, we explored complexity characterization and its existing shortcomings, including: lack of standardization, inconsistent semantics, system-centricity, insufficiently transparent reasoning, and lack of validation. To address these shortcomings, we proposed a compilatory framework to characterize complexity using the Five Ws information-gathering method. The answer to the WHO question proposed four complexity viewpoints; the answer to the WHY question proposed a two-dimensional structure for complexity drivers; and the answer to the WHAT question derived generalized complexity challenges. As a preliminary step to show the potential of the framework to characterize complexity, we used and validated it as a tool to structure general literature related to complexity. In general, our findings suggest that papers with complexity solutions do not frame their research within the complexity problem domain, hindering the contribution evaluation. Through the viewpoints, we identified general research gaps of six solution directions. From the drivers, we noted three observations in the discourse of complexity origins: (1) a system-driven tendency, (2) a preference for concreteness vs. abstraction, and (3) an unclear distinction between origins and effects. Through the challenges' findings we explored two hypotheses: (1) a system-centric preference; and (2) a solution-oriented vision, both of which were supported by the results (most challenges relate to the system viewpoint and challenges are defined based on solution directions).

The conference was held at the University of Paris 1-Pantheon Sorbonne.

The paper reveals a small chapter of the history of the development of metallurgical science and technology in the Soviet Union. The point at issue is the development of scientific contacts between the American and Soviet metallurgical scientists in the second half of the 1950s. The successes of the USSR in the space race had demonstrated to the Western countries the real scientific and economic power of the country and thus shown both the unconstructiveness of the policy of isolation and the benefits of economic cooperation. The high level of development of metallurgical science and technology in the USSR had thus surprised the American specialists. The Ural Polytechnic Institute was one of those universities visited by the American guests. This paper is devoted to this chapter of history and continues the material published earlier.

The article presents information on European Control Conferences that took place during 1991-2001. First European Control Conference was held in Grenoble, France in July 1991. Noteworthy is a high percentage of screened papers, which seems to be due to the fact that this was the first conference and a substantial part of papers were preplanned to some extent because they were presented at the 28 so-called invited sessions. The Seventh European Control Conference took place in Cambridge, Great Britain on September 14, 2003. The European Union recently pays much attention to increasing the standing of the European researchers in the international science and engineering. This was the main goal of organizing in 1990 the European Union Control Association.

Promoting ethical practice within an organization has been a continuous challenge in the business ethics community. To enrich organizational practices for promoting business ethics across an organization, this paper aims to introduce the voices of practitioners working in organizations that offer exemplary practices. Based on semi-structured interviews with 21 engineers working in the health products industry, we identified 12 pervasive ethical values that we grouped to four categories: fiduciary, economic, engineering, and process values. As ethics has been embraced as a core element of the ethical practice of our study participants regardless of their rankings and roles in their organizations, we investigated organizational strategies for promoting ethical practice. We identified four categories of organizational strategies: symbols, memberships, practices, and systems. Each strategy affected the 12 ethical values in different ways. Lastly, we identified three characteristics of the industry contexts that appeared to influence ethical values: customer impact, economic norms, and highly regulated industry. We discuss how the findings from this paper can potentially promote new discussions and practices in the business ethics community. [ABSTRACT FROM AUTHOR]

Complex systems are difficult to manage, operate and maintain. This is why we see teams of highly specialised engineers in industries such as aerospace, nuclear and subsurface. Condition based monitoring is also employed to maximise the efficiency of extensive maintenance programmes instead of using periodic maintenance. A level of automation is often required in such complex engineering platforms in order to effectively and safely manage them. Advances in Artificial Intelligence related technologies have offered greater levels of automation but this potentially pivots the weight of decision making away from the operator to the machine. Implementing AI or complex algorithms into a platform can mean that the Operators' control over the system is diminished or removed altogether. For example, in the Boeing 737 Air Max Disaster, AI had been added to a platform and removed the operators' control of the system. This meant that the operator could not then move outside the extremely reserved, algorithm defined, "envelope" of operation. This paper analyses the challenges of AI driven condition based monitoring where there is a potential to see similar consequences to those seen in control engineering. As the future of society becomes more about algorithm driven technology, it is prudent to ask, not only whether we should implement AI into complex systems, but how this can be achieved ethically and safely in order to reduce risk to life.

This work is the extended version of a paper presented at the conference HMM2021, about the history of mechanical engineering. First, the initial cultural and industrial steps in the robotic field in Japan are introduced, to display the beginning of this interlaced path, before WW2; then, in the context of the aftermaths of the war, some famous anime heroes are presented as ancestors of the coming mecha anime series. The rising research in the field of robotics and more generally the developments of contemporary Japanese automation industry are then drawn, as a technological substrate for mecha conception. In particular, Masahiro Mori studies are taken into consideration to identify an actual robot design pattern to apply to the following comparative description and examination of the different mecha; finally, thanks to this analysis, the common breeding ground whence robotics and mecha (and their reciprocal influences) arise, is outlined.

This theme section brings together the latest research at the intersection of artificial intelligence (AI) and model-driven engineering (MDE). Over the past years, we have witnessed a substantial rise of AI successfully applied to different domains, including software development and MDE. Dedicated events at the intersection of AI and MDE have been created, too, such as the MDE Intelligence workshop series co-located with the MODELS conference. This theme section covers research contributions integrating AI components into MDE approaches—increasing the current benefits of MDE processes and tools and pushing the limits of "classic" MDE with the goal to provide software and systems engineers with the right techniques to develop the next generation of highly complex model-based systems—and applications of MDE to the development of AI components. In total, nine submissions were accepted in the theme section after a thorough peer-reviewing process. [ABSTRACT FROM AUTHOR]

The background of this Special Issue (SI) of the Optimization and Engineering (OPTE) journal is the 2021 Sustainable Development of Energy, Water and Environment Systems (SDEWES) Conference. This broad field was discussed by the participants of the 16th SDEWES Conference held in Dubrovnik, Croatia. This SI aims to bring together articles that discuss recent advances in optimization methods and algorithms that integrate various life-supporting systems. A decision-making problem often appears as a parameter estimation problem; it can be formulated as an optimization model and solved using different optimization algorithms and techniques. All papers included in this OPTE journal SI consider aspects of numerical analysis, mathematical modelling, and computational methods involved in investigating, planning and implementing sustainable development. In this context, the guest editors have confidence that the selected papers and addressed issues will substantially contribute to the increase of the knowledge body published in the OPTE journal, and the SI will be a powerful platform for researchers to discuss, share, and disseminate new ideas.

The engineering vehicle detection is a key issue for the raw material warehouse scenes. Through the engineering vehicle detection, the working conditions of engineering vehicles in the raw material warehouse can be intelligently managed to prevent large-scale smoke pollution and the danger of smoke and dust. In this paper, we propose an intelligent method based on the framework of YOLOv4-Tiny for locating and identifying the engineering vehicles. In our detection task, the monitoring scenes are complex with a lot of interference. And the scope of monitoring is large. In order to solve these challenging problems, we introduce the Split-attention module to the network, which can adaptively extract important information of the image and improve the receptive field of detection. In addition, we introduce the Dynamic ReLU function to the network, which allow the network to adaptively learn more suitable ReLU parameters based on the input. We also collect a large number of images obtained from the front-end cameras and create a self-built dataset of engineering vehicles. In this paper, we test our method on the COCO dataset and the self-built engineering vehicle dataset. Experimental results show that our method proposed in this paper can detect engineering vehicles with higher accuracy and faster speed, which can be used for engineering vehicle detection in the scenes of raw material storage warehouses.

Model-driven engineering (MDE) is believed to have a significant impact in software quality. However, researchers and practitioners may have a hard time locating consolidated evidence on this impact, as the available information is scattered in several different publications. Our goal is to aggregate consolidated findings on quality in MDE, facilitating the work of researchers and practitioners in learning about the coverage and main findings of existing work as well as identifying relatively unexplored niches of research that need further attention. We performed a tertiary study on quality in MDE, in order to gain a better understanding of its most prominent findings and existing challenges, as reported in the literature. We identified 22 systematic literature reviews and mapping studies and the most relevant quality attributes addressed by each of those studies, in the context of MDE. Maintainability is clearly the most often studied and reported quality attribute impacted by MDE. Eighty out of 83 research questions in the selected secondary studies have a structure that is more often associated with mapping existing research than with answering more concrete research questions (e.g., comparing two alternative MDE approaches with respect to their impact on a specific quality attribute). We briefly outline the main contributions of each of the selected literature reviews. In the collected studies, we observed a broad coverage of software product quality, although frequently accompanied by notes on how much more empirical research is needed to further validate existing claims. Relatively, little attention seems to be devoted to the impact of MDE on the quality in use of products developed using MDE. [ABSTRACT FROM AUTHOR]

This paper aims to call attention to the potential of using film in engineering ethics education, which has not been thoroughly discussed as a pedagogical method in this field. A review of current approaches to teaching engineering ethics reveals that there are both learning outcomes that need more attention as well as additional pedagogical methods that could be adopted. Scholarship on teaching with film indicates that film can produce ethical experiences that go beyond those produced by both conventional methods of teaching engineering ethics and more arts-based methods such as fiction, as well as connect ethics learning outcomes and issues to the lifeworld of a person. The paper further illustrates the potential of using Miyazaki Hayao’s film The Wind Rises for highlighting a range of ethical issues pertaining to engineering. It also discusses the important role educators play in how film can be used effectively in the classroom. Synthesizing a range of sources from film theory to the use of film in business and medical education, the paper makes the case for using film in engineering ethics education and calls for more research on the use of this method.
