Software engineering for machine learning applications

Both Software Engineering and Machine Learning have become recognized disciplines. In this article I analyse the combination of the two: engineering of machine learning applications. I believe the systematic way of working for machine learning applications is at certain points different from traditional (rule-based) software engineering. The question I set out to investigate is “How does software engineering change when we develop machine learning applications”?. This question is not an easy to answer and turns out to be a rather new, with few publications. This article collects what I have found until now.

The future of continuing engineering education in the era of digitalization and personalization

The pace of introduction of new technology and thus continuous change in skill needs at workplaces, especially for the engineers, has increased. While digitization induced changes in manufacturing, construction and supply chain sectors may not be felt the same in every sector, this will be hard to escape. Both young and experienced engineers will experience the change, and the need to continuously assess and close the skills gap will arise. How will we, the continuing engineering educators and administrators will respond to it? Prepared for engineering educators and administrators, this workshop will shed light on the future of continuing engineering education as we go through exponentially shortened time frames of technological revolution and in very recent time, in an unprecedented COVID-19 pandemic.

Pragmatic Models

This chapter discusses several aspects related to engineering methods in wind turbine design codes. Current engineering models for rotor aerodynamics topic are built around the Blade Element Momentum (BEM) theory. The Blade Element Momentum theory in itself is very basic, e.g., it is derived for two-dimensional, stationary, homogenous, and non-yawed conditions. For this reason, several engineering models have been developed which overcome these simplifications and which act as add-ons to the basic BEM theory. This chapter describes the BEM theory, the most important engineering add-ons, and an assessment of BEM with engineering add-ons with results from higher fidelity models and measurements.

Social Engineering as an Approach for Probing Organizations to Improve IT Security

From the article: This paper describes the external IT security analysis of an international corporate organization, containing a technical and a social perspective, resulting in a proposed repeatable approach and lessons learned for applying this approach. Part of the security analysis was the utilization of a social engineering experiment, as this could be used to discover employee related risks. This approach was based on multiple signals that indicated a low IT security awareness level among employees as well as the results of a preliminary technical analysis. To carry out the social engineering experiment, two techniques were used. The first technique was to send phishing emails to both the system administrators and other employees of the company. The second technique comprised the infiltration of the office itself to test the physical security, after which two probes were left behind. The social engineering experiment proved that general IT security awareness among employees was very low. The results allowed the research team to infiltrate the network and have the possibility to disable or hamper crucial processes. Social engineering experiments can play an important role in conducting security analyses, by showing security vulnerabilities and raising awareness within a company. Therefore, further research should focus on the standardization of social engineering experiments to be used in security analyses and further development of the approach itself. This paper provides a detailed description of the used methods and the reasoning behind them as a stepping stone for future research on this subject. van Liempd, D., Sjouw, A., Smakman, M., & Smit, K.

Engineering honours program

In September 2009 the department of Engineering of Fontys University of Applied Sciences in the Netherlands has started a pilot honours program for excellent engineering students called PRogram OUstanding Development (PROUD). Aim of this program is to give those engineering students, who have the ambition, the opportunity to work on extra profession related challenges in their study. By means of this PROUD program Fontys University of Applied Sciences is responding to the wishes of students for extra curricular activities and increasing need from the industry for excellent professionals with an extra level of theoretical knowledge and practical experience. In this paper the courses offered at the Engineering department of the Fontys University of Applied Sciences are discussed. Different study possibilities/routings for students were developed depending on earlier acquainted competences, adaptation abilities to our system (special possibilities for slow starters) and tracking and tracing by intensive study coaching. This resulted in an improvement of the yield of students to 74% of students started in 2008. After working successfully on reducing the drop out rate of our engineering students the department focused on possibilities for excellent students. The department started the PROUD pilot together with engaged engineering students. In 2008 engineering students have carried out a research among their fellow students, lecturers, other institutes [1] and industry. This resulted in a quite different approach of an honours program for the department of Electronic and Electrical Engineering. In the PROUD program the student is stimulated to personally shape his educational career and to explicitly work on developing his own competences. The PROUD excellent program starts after the first year and extends to at least 3 semesters in the following years. The student, guided by a supervisor and outside the regular study time, is working on building an excellent portfolio at the university as well as in industry. During this period the PROUD student will work in industry one day a week in average. This is on top of his bachelor educational program. The students will receive an excellent honours certificate together with their bachelor's degree at the end of the study to express their honourable work. Each year about 20 students apply for a place in PROUD but thus far only about 3-4 passed the first interview round. It turns out that student, university and industry are eager to participate in this PROUD program.

[STEPS] Sustaining the Social: Design Guidelines for Sustainable Public Space

Designing cities that are socially sustainable has been a significant challenge until today. Lately, European Commission’s research agenda of Industy 5.0 has prioritised a sustainable, human-centric and resilient development over merely pursuing efficiency and productivity in societal transitions. The focus has been on searching for sustainable solutions to societal challenges, engaging part of the design industry. In architecture and urban design, whose common goal is to create a condition for human life, much effort was put into elevating the engineering process of physical space, making it more efficient. However, the natural process of social evolution has not been given priority in urban and architectural research on sustainable design. STEPS stems from the common interest of the project partners in accessible, diverse, and progressive public spaces, which is vital to socially sustainable urban development. The primary challenge lies in how to synthesise the standardised sustainable design techniques with unique social values of public space, propelling a transition from technical sustainability to social sustainability. Although a large number of social-oriented studies in urban design have been published in the academic domain, principles and guidelines that can be applied to practice are large missing. How can we generate operative principles guiding public space analysis and design to explore and achieve the social condition of sustainability, developing transferable ways of utilising research knowledge in design? STEPS will develop a design catalogue with operative principles guiding public space analysis and design. This will help designers apply cross-domain knowledge of social sustainability in practice.

Additive Application of Soldermasks

Printplaten (PCB's) zijn essentieel in elektronische producten. Ze bestaan uit een drager, geleidende kopersporen en een beschermende soldermask-laag. PCB's worden geproduceerd via fotolithografie en etstechnieken, wat kostenefficiënt is voor massaproductie, maar niet voor kleine oplages. Dit vormt een probleem wanneer bedrijven één PCB nodig hebben, bijvoorbeeld in de ontwerp- of prototypefase en bij eenmalige installaties. Bedrijven zoals 100%FAT en Edulogics bestellen dan meerdere PCB's, waarvan ze slechts één gebruiken. PCB-productiebedrijf DeltaProto beaamt dat bijna al hun klanten op deze manier werken. Dit leidt tot verspilling. Bovendien maken bedrijven zich, bij uitbesteding van PCB-productie, zorgen over veiligheid van hun ontwerpen en ecologische voetafdruk van productie en verzending. Digital manufacturing maakt het mogelijk om in-house PCB’s te maken. Dit biedt flexibiliteit en snelheid, maar het ontbreekt aan een methode om een kwalitatief goede soldermask-laag aan te brengen. Deze PCB’s voldoen niet aan industrie-standaarden, waardoor bedrijven deze methode niet gebruiken. Dit project richt zich op de ontwikkeling van een methode voor additive manufacturing, zoals inkjet-printing, van soldermask op PCB's, zodat ze voldoen aan industrie-standaarden. Additive manufacturing wordt digitaal gestuurd dus maakt snelle ontwerpwijzigingen mogelijk en materiaal wordt alleen aangebracht waar nodig. Dit minimaliseert verspilling, verlaagt opstartkosten en maakt in-house productie van prototype-PCB’s geschikt voor professioneel gebruik. Een eenjarig verkennend onderzoek is nodig om technische uitdagingen en eisen voor het aanbrengen van een soldermask-laag te begrijpen en een prototype te ontwikkelen als proof-of-concept. Wanneer deze technologie wordt ontwikkeld, zal in-house PCB-productie bijdragen aan sneller, beter en verantwoord ontwerpen van elektronica. Dit projectvoorstel past binnen het innovatiedomein Smart Industry door de focus op flexibele en duurzame productie van prototype-PCB's. Het draagt bij aan technologieontwikkeling en heeft een duidelijke maatschappelijke impact. Daarnaast sluit het aan bij innovatiedomeinen Mechatronics en Optomechatronics en sleutel technologieën Advanced Materials en Engineering and fabrication technologies, wat de relevantie verder onderstreept.

Alignment aUtomation Tool for Optically Coupled single-Use sEnsors (AUTOCUE)

Various companies in diagnostic testing struggle with the same “valley of death” challenge. In order to further develop their sensing application, they rely on the technological readiness of easy and reproducible read-out systems. Photonic chips can be very sensitive sensors and can be made application-specific when coated with a properly chosen bio-functionalized layer. Here the challenge lies in the optical coupling of the active components (light source and detector) to the (disposable) photonic sensor chip. For the technology to be commercially viable, the price of the disposable photonic sensor chip should be as low as possible. The coupling of light from the source to the photonic sensor chip and back to the detectors requires a positioning accuracy of less than 1 micrometer, which is a tremendous challenge. In this research proposal, we want to investigate which of the six degrees of freedom (three translational and three rotational) are the most crucial when aligning photonic sensor chips with the external active components. Knowing these degrees of freedom and their respective range we can develop and test an automated alignment tool which can realize photonic sensor chip alignment reproducibly and fully autonomously. The consortium with expertise and contributions in the value chain of photonics interfacing, system and mechanical engineering will investigate a two-step solution. This solution comprises a passive pre-alignment step (a mechanical stop determines the position), followed by an active alignment step (an algorithm moves the source to the optimal position with respect to the chip). The results will be integrated into a demonstrator that performs an automated procedure that aligns a passive photonic chip with a terminal that contains the active components. The demonstrator is successful if adequate optical coupling of the passive photonic chip with the external active components is realized fully automatically, without the need of operator intervention.

An exploratory case study: In search of key enabling factors for effective participatory design for socio-technical innovation

The pace of technology advancements continues to accelerate, and impacts the nature of systems solutions along with significant effects on involved stakeholders and society. Design and engineering practices with tools and perspectives, need therefore to evolve in accordance to the developments that complex, sociotechnical innovation challenges pose. There is a need for engineers and designers that can utilize fitting methods and tools to fulfill the role of a changemaker. Recognized successful practices include interdisciplinary methods that allow for effective and better contextualized participatory design approaches. However, preliminary research identified challenges in understanding what makes a specific method effective and successfully contextualized in practice, and what key competences are needed for involved designers and engineers to understand and adopt these interdisciplinary methods. In this proposal, case study research is proposed with practitioners to gain insight into what are the key enabling factors for effective interdisciplinary participatory design methods and tools in the specific context of sociotechnical innovation. The involved companies are operating at the intersection between design, technology and societal impact, employing experts who can be considered changemakers, since they are in the lead of creative processes that bring together diverse groups of stakeholders in the process of sociotechnical innovation. A methodology will be developed to capture best practices and understand what makes the deployed methods effective. This methodology and a set of design guidelines for effective interdisciplinary participatory design will be delivered. In turn this will serve as a starting point for a larger design science research project, in which an educational toolkit for effective participatory design for socio-technical innovation will be designed.

Anthocyanins from agricultural waste: a source of next generation antimicrobials?

To treat microbial infections, antibiotics are life-saving but the increasing antimicrobial resistance is a World-wide problem. Therefore, there is a great need for novel antimicrobial substances. Fruit and flower anthocyanins have been recognized as promising alternatives to traditional antibiotics. How-ever, for future application as innovative alternative antibiotics, the full potential of anthocyanins should be further investigated. The antimicrobial potential of anthocyanin mixtures against different bacterial species has been demonstrated in literature. Preliminary experiments performed by our laboratories, using grape, rose and red cabbage anthocyanins against S. aureus and E. coli confirmed the antimicrobial potential of these substances. Hundreds of different anthocyanin entities have been described. However, which of these entities hold antimicrobial effects is currently unknown. Our preliminary data show that an-thocyanins extracted from grape, rose and red cabbage contain different collections of anthocyanin entities with differential antimicrobial efficacies. Our focus is on the extraction and characterization of anthocyanins from various crop residues. Grape peels are residues in the production of wine, while red rose and tulip leaves are residues in the production of tulip bulbs and regular horticulture. The presence of high-grade substances for pharmacological purposes in these crops may provide an innovative strategy to add value to other-wise invaluable crop residues. This project will be performed by the collaborative effort of our institute together with the Medi-cal Microbiology department of the University Medical Center Groningen (UMCG), 'Wijnstaete', a small-scale wine-producer (Lemelerveld) and Imenz Bioengineering (Groningen), a company that develops processes to improve the production of biobased chemicals from waste products. Within this project, we will focus on the antimicrobial efficacy of anthocyanin-mixtures from sources that are abundantly and locally available as a residual waste product. The project is part of a larger re-search effect to further characterize, modify and study the antimicrobial effects of specific anthocy-anin entities.
