Brainport Eindhoven: born from crisis - 25 years as a Triple Helix Governed Ecosystem
Authors: Bronneberg Mark , Pieterse Jos , Post Ger 
Published: May 2023

Various researchers have called for research into positive examples of successful triple helix governed ecosystems. Triple Helix collaborations are seen as the solution to tackle the current ‘wicked problems’ of society. Researchers are encouraged to enhance our understanding of governing inter-organizational collaborations (ecosystems) in the context of university-industry-government (Triple Helix) relations. In this paper we therefore describe a case study of the Brainport Eindhoven ecosystem in the Netherlands which embodies a triple helix organization and how the regional governmental structure (Brainport Foundation and Brainport Development) on the one hand stabilizes at a strategic level and on the other hand gives flexibility at the tactical and operational level. This leads to the transfer of knowledge and to innovation and change within the network. Using mixed methods of 1) analysis of (strategic) documents about the regional governance used and how the Brainport Eindhoven mission evolved through time; 2) semi-structured interviews with current and former Brainport Foundation board members and former Brainport Development managers; and 3) network participant observations; we reveal rich experiences from 25 years of Brainport Eindhoven. This research shows the historical overview of Brainport Eindhoven and how the triple helix parties together managed several regional or worldwide crises. This togetherness was crucial in the development of a successful regional ecosystem. Our findings illustrate the fragile balance between stability and flexibility within the ecosystem and its governance based on processes of common sensemaking by all stakeholders. Our paper contributes to a better understanding of the development and governance of triple helix entrepreneurial ecosystems. Finally, this paper makes suggestions for future research by discussing the ambition to transform the ecosystem into a Quadruple Helix (adding the ‘community’ as a fourth pillar) organized ecosystem.
Genetic-Algorithm-Guided Development of Parametric Aeroelastic Reduced-Order Models with State-Consistence Enforcement
Authors: Shu Jung I. , Wang Yi , Brown Alessandro , Kaminsky Andrew 
Published: May 2023

Data-driven parametric reduced-order models (ROMs) in state-space form are valuable tools for rapid aeroelastic (AE) analysis and aerostructure control synthesis. However, the issue of state inconsistence (significant variations in model parameters over tradespaces) makes ROMs noninterpolatable, and therefore unable to accommodate use over broad flight parameter space. This paper presents a holistic framework that combines a system identification technique with state-consistence enforcement (SCE) and a genetic algorithm (GA) for the automated development of interpolatable AE ROMs across broad flight regimes. The SCE technique introduces a regularization term to the AutoRegressive model with eXogenous inputs (ARX) to specifically penalize model parameter variation between flight conditions. The GA autonomously guides the ROM development process toward optimal SCE-ARX hyperparameter selection that balances between model parameter variations and ROM accuracy. The GA-guided SCE-ARX approach is applied to build a parametric AE-ROM database at selected flight conditions, which, because of its state consistence, can be interpolated to create ROMs at any interstitial conditions, where training data or ROMs are not initially available, hence rapidly establishing the full coverage of the entire parameter space. The ROMs generated by the proposed method are compared with those by ARX, SCE, and GA-guided ARX in prediction accuracy. The individual and combined effects of SCE and GA on model parameter variation and ROM interpolatability are thoroughly investigated. The present method demonstrates the most accurate and robust performance for parametric ROM construction across the broad flight envelope.

Published: May 2023

Rekam jejak Jawara di Bekasi, telah ada sejak masa kolonial. Keberadaan Jawara di tanah partikelir di Bekasi saat itu menjadi penting, bagi para tuan tanah. Berkat kepiawaiannya dalam ilmu bela diri, serta ilmu kekebalan yang dimilikinya, para tuan tanah menempatkan Jawara sebagai kepala keamanan dan pengawas para pekerja perkebunan, serta penarik pajak. Karena diberikan akses kepercayaan dari tuan tanah, Jawara dalam menjalankan tugasnya kerap kali melakukan tindakan sewenang – wenang kepada penduduk yang tidak ingin membayar pajak, hingga merampas harta benda, sehingga dikemudian hari menimbulkan perlawanan dari penduduk. Seiring perjalan waktu, Jawara yang semula dipandang keji berubah peran menjadi agen penggerak di masa revolusi kemerdekaan 1945- 1949. Kehadiran tokoh lokal Haji Djoleh, Camat Nata, Pak Macem, tidak dapat dikesampingkan dari historiografi lokal mereka memiliki peran yang besar dalam perjuangan mempertahankan kemerdekaan di Bekasi Oleh karena itu, permasalahan yang diajukan dalam artikel ini adalah bagaimana peranan Jawara dalam revolusi kemerdekaan di Bekasi Penulisan artikel ini menggunakan metode sejarah tahapannya, meliputi heuristik, kritik, interpretasi, historiografi. Kata Kunci: Peran; Jawara; Bekasi; Masa Revolusi. AbstractJawara's track record in Bekasi has existed since colonial times. Jawara's presence in the land in Bekasi at that time became important, for the landlords. Thanks to his expertise in martial arts, as well as his immunity, the landlords placed Jawara as the head of security and supervisor of plantation workers, as well as a tax collector. Because they were given access to trust from landlords, Jawara in carrying out their duties often carried out arbitrary actions to residents who did not want to pay taxes, to the point of depriving them of property, so that in the future it would cause resistance from the residents. Over time, Jawara, who was originally seen as heinous, changed his role as a driving agent during the independence revolution of 1945-1949. The presence of local figures Haji Djoleh, Nata Sub-district Head, Pak Macem, cannot be excluded from local historiography, they have a big role in the struggle to maintain independence in Bekasi Therefore, the problem posed in this article is how the role of Jawara in the independence revolution in Bekasi The writing of this article uses the historical method of its stages, including heuristics, criticism, interpretation, historiography.

The Role of Leadership in Digital Learning Organizations
Authors: Hargitai Dávid Máté , Bencsik Andrea 
Published: May 2023

The study aims to examine the relationship and interaction between learning organization culture and the factors influencing digital transformation (leadership style, training, digital readiness, and trust), as well as identify factors that significantly influence learning organization functioning by exploring the extension of a grounded theory framework. The survey was conducted using an online questionnaire. The survey population was composed of managers of Eastern European manufacturing companies who were reached through the Orbis database. The survey yielded 618 evaluable responses (n = 618). The PLS-SEM method was used because the structural model is complex, with many constructs (some of which are formatively measured) and model relationships. Leadership behavior and a supportive management style inspire the development and training of employees, through which the level of readiness for digitalization and Industry 4.0 technologies can be increased. Training in these skills will increase confidence in digitalization technologies. Leadership support also influences digital trust and employee response to the use of digital technologies, as does participation in training, which directly supports digitalization and I4.0 readiness. The results of the research not only support previous research findings but also complement them by focusing specifically on the impact on the learning organization in the context of digitalization. This study provides evidence that leadership that is supportive of the learning organization's culture plays a key role. Overall, leadership is a dominant influence in the digital transformation of organizations and in shaping the learning organization culture this requires, but all the relationships represented in the model have a significant positive relationship.

Published: May 2023

Kertosari Village is one of the centers for “marning” corn-processed products in Situbondo. Until now there are three corn-marketing UKMs in Kertosari Village whose products are marketed outside the city, such as Banyuwangi, Malang, to Jakarta. However, so far UKMs have not implemented GMP in their production processes and tend to use makeshift production rooms with simple tools. Thus, food safety, competitiveness, and product quality are still not a priority for UKMs. The layout of the production process is not by following under GMP principles. This happened because of their limited knowledge and skills regarding GMP principles. Therefore, an extension on the application of GMP principles needs to be done to improve product quality and safety. In addition, GMP principles can also guarantee the health and safety of workers. An extension on the application of GMP principles was carried out using the focus group discussion (FGD) method. The material presented includes the concept of food safety, contamination related to processed food production, and GMP principles. The results of the extension show an increase in knowledge by 25%.

Influence of Surface Geometry and Microstructural Features on the Delamination and Crack Propagation of Brittle Convex Thermal Barrier Films during Thermal Cyclic Loading
Authors: Nastic Aleksandra , Pershin Larry , Mostaghimi Javad 
Published: May 2023

Abstract
The influence of air plasma sprayed alumina coating geometry, microstructure, interface roughness on its delamination and crack propagation resistance during low temperature thermal cycling, i.e. thermal mismatch stress, is investigated both numerically and experimentally. Previous studies on thermal cycling loading concentrate on flat, numerically designed locally curved specimens and/or mathematically modeled roughness without extension towards real coating morphology, which renders the conclusions less practically driven. Results show that arbitrarily oriented cracks originate predominantly near the coating/substrate interface and propagate along zones of high tensile and shear residual stress. The crack path deflection was attributed to the complex stress concentration structure resultant from the intricate microstructural porosity and coating general convex geometry. Microstructural features such as porosity increase the interfacial and coating tensile stress, which may lead to important delamination processes even during low temperature thermal cycling.

Abstract
A new challenge in the transport systems concerns with improving efficiency. Thermal swing coatings are interesting candidates for internal combustion engines due to their potential to reduce cooling requirements and increase efficiency. K2Ti6O13 (KTO) thermal barrier coatings (TBCs) were prepared by atmospheric plasma spraying through powder structure design and optimization of deposition conditions. The thermophysical properties of plasma-sprayed KTO deposits and their effect on the thermal swing have been investigated. Their thermal conductivities were tested by a laser flash method and the thermal performance of the coatings was further examined by thermal swing test. The phases, nominal chemical compositions and microstructure of KTO deposits were characterized by X-ray diffraction (XRD) and scanning electron microscopy combined with energy dispersive spectrometry (SEM-EDS). The results indicated that the chemical composition change occurs to the coatings resulting in a deviation from nominal stoichiometry due to chemical reactions between the plasma gas and particles. The thermal conductivity of the coating is very sensitive to the coating compositions, and the coating prepared using porous powder under pure argon presents a single K2Ti6O13 phase and high porosity, and the lowest thermal conductivity of 0.85 W/m·K.
Enhancing Production Control for PTWA Engine Bore Coating

Published: May 2023

Abstract
Plasma Transferred Wire Arc (PTWA) is a well-established thermal spray process that is used in high-volume production by multiple automotive OEMs. Benefits of these PTWA thermal spray coatings include closer bore spacing, improved thermal transfer, lower bore distortion, increased resistance to corrosion and abrasion, reductions in weight and friction, enhanced durability, and product cost savings. For automobiles, this leads to increased fuel economy and lower emissions. Millions of engine cylinder bores per year are coated using the PTWA thermal spray process. To ensure optimal surface coatings, it is vital to monitor the process variables. Although some process monitoring already exists in current production, new technological advancements allow for additional variables to be monitored. Arc voltage is of particular importance as it can be viewed real-time in situ to the PTWA process to determine the curvature of the feedstock wire. Straight wire is ideal for achieving peak system performance. If the wire has excessive curvature, it can lead to out-of-tolerance conditions that detrimentally affect the quality of the surface coating. Therefore, in-situ monitoring of wire curvature is both desirable and necessary for producing the highest quality PTWA thermal spray coatings possible.
