Characterization of welding notch designs and the impact on mechanical properties of 3D-printed PLA parts joined by a 3D pen
(Editorial Universitat Politècnica de València, 2023-01-10) Michalak, Martin; Boca, Marius-Andrei; Sover, Alexandru
[EN] 3D-printing has been established as a fast and low-cost technology to produce prototypes in small numbers. However, depending on the geometry of a part the print time still can be reduced by splitting the part in two or more smaller parts and later joining them. The reduction of the print time is caused by the possibility of printing the smaller parts with less or maybe even without any support or the use of two or more 3D printers. The joining can be done by different welding or gluing methods. For this paper 3D printed polymer parts with different welding notch designs were welded by a 3D pen and after characterized based on their mechanical properties. The notches were designed in CAD and the parts were then 3D printed. The material chosen was PLA as it is one of the most common polymer materials for FFF 3D printing. For testing and mechanical characterisation of the strength of the joined samples, four different kinds of notches were designed, manufactured and tested according to the norms for the tensile strength test and the Charpy impact test of thermoplastic polymers. The results were compared to the one of a single part printed sample. Although the mechanical properties of the welded samples were not as good as the ones of a fully printed one, the assembly even of the weakest variant, the triple notch, is still strong enough for most applications in the field of rapid prototyping. The method is easy applicable and can be fast done to ensure a good connection between 3D printed PLA parts.

Design and testing of multi-material flexure hinges for Fused Filament Fabrication
(Editorial Universitat Politècnica de València, 2023-01-10) Ermolai, Vasile; Sover, Alexandru; Nagît, Gheorghe
[EN] Flexure hinges are non-assemble flexible joints that allow the relative rotation of two adjacent rigid parts through bending. Traditionally thermoplastic material hinges are made through injection moulding. 3D printing technologies such as Fused Filament Fabrication (FFF) introduced new possibilities regarding hinges development due to design freedom and the availability of multiple materials. However, the current state of the art focuses mainly on single materials hinges with non-symmetrical design for one-way folding. For this reason, this paper aimed to identify and test multiple design solutions for two-way folding hinges made of compatible and low-compatible thermoplastic materials using design thinking methods. The design process considered the materials' bond formation, resulting in overlapping designs for compatible materials and interlocking designs for the others. The considered materials were acrylonitrile butadiene styrene (ABS) and polylactic acid (PLA) with thermoplastic co-polyesters (TPC) for the hinge. The resulting designs of multi-material two-way folding hinges were tested using a tensile test to evaluate the performance of the interlocking mechanism. The results show that macroscopic interlocking provides the best results.

A model to explore circular economy activities in hotels and restaurants
(Editorial Universitat Politècnica de València, 2023-01-10) Sánchez-Planelles, Joaquín; Trujillo-Adriá, Yolanda; Silva-Cardenas, Belén; de-Miguel-Molina, María; Departamento de Organización de Empresas; Facultad de Administración y Dirección de Empresas; Agència Valenciana de la Innovació
[EN] This work explores the different frontline and offline activities during the use of hotels and restaurants -represented as the touchpoints of a customer journey- to establish what circular actions could be implemented by stakeholders throughout the process, which lead to more circular business models that integrates the seven R’s (redesign, reduce, reuse, reneovate/repair,refurbish/remanufacture, recover/return and recycle) to achieve more efficient and sustainable performance. From the reservation step to the customer satisfaction evaluation, the interactions of hotels or restaurants with suppliers from many different economic sectors determine a variety of activities in their value chain that creates synergies, enhance circularity and add value to the tourism sector through the implementation of sustainable practices or the acquisition of sustainable products and services. Based on the literature, reports and lessons learned in the sector through specific Focus Groups previously carried for the research team, the proposed model can help hotels and restaurants decision-makers to take steps toward circular economy.

Sustainable recruitment and development of qualified professional staff at universities of applied sciences
(Editorial Universitat Politècnica de València, 2023-01-10) Gröner, Patrick; Hedderich, Barbara; Dittrich, Lena
[EN] Due to the double qualification of a PhD and five years of professional experience outside of higher education, it is very difficult for universities of applied sciences to recruit good professors in specific areas such as certain areas of computer science. Since such a shortage of qualified professors can lead to considerable deficits in higher university development, the present structured personnel recruitment procedure for universities of applied sciences was developed.

Influence of cooling conditions during 3D printing on the switching temperature of a TPU with SME
(Editorial Universitat Politècnica de València, 2023-01-10) Lang, Anette; Boca, Marius-Andrei; Sover, Alexandru
[EN] Shape memory polymers (SMP) are materials with a special structure, designed to react to a certain stimulus. Using such SMPs with 3D printing technology opens up further fields of application thus providing for the so-called 4D printing. After such a printing process it is mandatory for the SMP to still be able to form a crystalline structure, maintaining its own shape memory effects (SME). The crystalline portion or the hard section of polymers is strongly influenced by the cooling rate during the printing process. In order to evaluate the influence of the cooling on the formation of the segments, thermal measurements using Differential Scanning Calorimetry (DSC) were carried out. The test shows that the cold crystallization was evident in each case in the first heating run, but the cooling rate in the FFF (Fused Filament Fabrication) technology could not be reduced to such a level that the switching temperature changed. In order to have an influence on the melt peak, the cooling rate must be increased further. This was demonstrated in the 2nd heating run of the DSC measurements.

Having a real prototype of your own product design – small effort but big eureka moment for students
(Editorial Universitat Politècnica de València, 2023-01-10) Riess, Christian; Walter, Michael; Tyroller, Maria; Gomolka, Lisa; Augustin, Johannes; Altieri, Mike; CLAAS Foundation; Stiftung Innovation in der Hochschullehre
[EN] This paper presents a project-based product design course, which is the only course on product design in our curriculum. We noticed that the building of a prototype is often omitted in academic teaching. However, students benefit from building a prototype of their design. Hence, we reduced the theoretical content to give students time to design and build a prototype. To illustrate the course two student projects are shown. We want to motivate lecturers to introduce prototyping to courses, since our experience is that the benefits of building a prototype outweigh the decrease in theoretical knowledge.

Connect.Me: A Step Towards Hybrid Intelligence
(Editorial Universitat Politècnica de València, 2023-01-10) Lanquillon, Carsten; Schacht, Sigurd
[EN] Artificial Intelligence (AI) is drastically transforming the world around us. Rather than replacing humans, hybrid intelligence combines human and machine intelligence to leverage each of their individual strengths. We summarize different requirements and approaches identified to achieve hybrid intelligence and focus on conversational AI to build a cognitive agent that supports knowledge management within an organization. The agent automatically extracts knowledge from artifacts provided or published by the users. In addition, the knowledge base steadily grows while the agent talks to the users and the users provide feedback and the system is continuously learning to extract new types of entities and relations to answer more questions based on the knowledge graph and to access other sources of information. The first types of entities and relations extracted already support users in finding colleagues with relevant skills or interests. Based on information provided by the agent, collaboration among employees and, thus, knowledge sharing and transfer is encouraged. The collaboration between the cognitive agent as an AI artifact and employees combined with a system that learns and adapts while in use stressing explainability and trust in its answers entails a step towards hybrid intelligence.

[EN] The Circular Economy opens a scenario of key business opportunities to improve tourism firms' competitiveness now and in the future. InnoEcoTur is a research project promoting models and strategies based on the Circular Economy in the tourism sector by the creation of a network in the area of hotels and restaurants. Members of the network will analyze first and later propose the implementation of a Circular Economy Strategy for the Tourist Sector of the Valencian Community, transferring also the results to companies of the industry. In the first stage of the project, we performed an audit of the industry needs and detected the potential improvements through the participation of the different stakeholders involved using focus groups. In this paper, we justify the design of the focus groups parameters such as size, location, or type of stakeholder to gather meaningful information for analysis. The methodology reveals to be adequate to draw a rough picture of the situation of Circular Economy in hotels and restaurants in the Valencian Community.

(Editorial Universitat Politècnica de València, 2023-01-10) Didion, Eva; Ambrosius, Ute; Perello-Marin, M Rosario; Catalá-Pérez, Daniel; Departamento de Organización de Empresas; Facultad de Administración y Dirección de Empresas; Escuela de Doctorado
[EN] The literature on Organizational Socialization and Onboarding has assumed traditional work relationships located on-site in the company. Due to the Corona pandemic, remote work has gained tremendous importance. However, we do not yet know how the lack of physical presence affects organizational socialization. The research interest is to assess papers analyzing virtual organizational socialization systematically. The method used was a Systematic Literature Review (SLR). A protocol was made. In this, the search parameters were recorded. Literature relevant to the research question was identified and evaluated. This was examined and put into context. Key Findings: virtual organizational socialization represents a research gap. The literature is scattered; we only found a small number of relevant articles from different disciplines focusing on impediments of virtual organizational socialization. Research on onboarding practices that help overcome obstacles imposed by a higher degree of virtual work is needed.

Development of recyclable jointless plastic grippers for use in the medical technology sector
(Editorial Universitat Politècnica de València, 2023-01-10) Sover, Alexandru; Zink, Markus; Boca, Marius-Andrei; Schönbucher, Thomas; AiF Projekt GmbH
[EN] Medical grippers can be used for various purposes. They are a standard instrument in medical technology and are widely used every day for multiple applications. Jointless grippers, which, due to their geometry and material properties, allow for an easy gripping function, are very welcome to the medical sector in order to make the work and especially the hygiene or sterilisation of the products easier. The application of a single-use instrument made of thermoplastic and 100% recyclable plastic is an ideal response to the current trend toward the increasingly frequent application of single-use instruments in medical technology. Moreover, the infected plastic material can be easily disposed of. The development of a new type of gripper made of plastic is a step towards partially fulfilling this need. This article presents the development and validation of a jointless medical gripper produced by additive manufacturing and injection moulding technologies, using a compliant mechanism and thermoplastic material.

Public Perception of nonpharmacological interventions for COVID-19-pandemic containment
(Editorial Universitat Politècnica de València, 2023-01-10) Bölz, Annika; Gaisser, Sibylle
[EN] Since the end of 2019, the COVID-19 pandemic has been weighing heavily on countries worldwide. Different measures have been taken in Germany to combat this pandemic. In addition to nonpharmacological measures, vaccination strategies have been used to contain the pandemic. A retrospective survey was conducted to get a snapshot of what the population thinks about these measures and how they prefer to be informed. It collected attitudes of the inhabitants of Ansbach towards the COVID-19 situation in June 2020, June 2021 and December 2021. The survey shows that there was a change of opinion regarding the measures and the behaviour on the part of the government as the pandemic progressed. While occupational restrictions decreased, the positive opinion of the undertaken measures decreased. The fear of infection is steadily decreasing. After a sharp rise of the fear of economic consequences in June 2021, it decreases again in December 2021.

(Editorial Universitat Politècnica de València, 2023-01-10) Garcia-Ortega, Beatriz; Catalá-Pérez, Daniel; de-Miguel-Molina, Blanca; de-Miguel-Molina, María; Departamento de Organización de Empresas; Facultad de Administración y Dirección de Empresas; Escuela Técnica Superior de Ingeniería Informática; Escuela de Doctorado
[EN] The literature has widely investigated the risks from the perspective of the companies adopting new and disruptive technologies. However, less attention has been paid from the side of the providers of such technologies. This paper aims to address this gap by assessing and initiating a discussion on the reported risk factors in the annual reports of five of the considered top providers of cloud computing services: Amazon, Google, IBM, Microsoft, and Alibaba, characterized by their avant-garde or disruptive technologies, their dependence on the internet and technological infrastructure, and their operation on a global scale. As main contributions, this research offers from the viewpoint of these companies a classification of the intrinsic risk factors related to their specific nature, grouped by subjects, along with the potential derived negative impacts on their businesses, and critically discusses some positive aspects and some potentially missing factors to be further addressed. Through this paper, we prepare the avenue for ongoing research, including more companies and further assessment methods and criteria to further expand and enrich the findings.

(Editorial Universitat Politècnica de València, 2023-01-10) Korder, Benjamin; Maheut, Julien; Konle, Matthias; Departamento de Organización de Empresas; Escuela Técnica Superior de Ingeniería Industrial; Grupo de Investigación en Reingeniería, Organización, trabajo en Grupo y Logística Empresarial - ROGLE
[EN] Recently, supply chains had to cope with various exogenic disruptions. These disruptions are resulting in cascading failures that are spreading across all the supply networks, a phenomenon called the Ripple. Analyzing this phenomenon is the goal of this protocol. To do so, this paper aims to describe the structural steps of the protocol used to carry out an upcoming systematic literature review. Furthermore, the planned work on the way to the final literature review is defined. Therefore, research questions, for a qualitative argumentation with the ripple effect are phrased. The aim is to find out how resilient supply chain networks react on the ripple effect, how the effects of the exogenic shocks can be measured to compare supply chain networks, and which simulation techniques are appropriate to justify and quantify the results. Furthermore, the target quantitative bibliometric analyze patterns are defined and a brief conclusion is capturing achievments and stating out next steps.

On the intelligence of interacting autonomous robots and virtual agents
(Editorial Universitat Politècnica de València, 2023-01-10) Geißelsöder, Stefan; Narovlyanskyy, Andriy
[EN] This work explains some aspects why it is hard to pinpoint what intelligence is and more specifically, how to assess the intelligence of AI. It motivates a setup that is designed to foster the investigation of this question using reinforcement learning agents as complex AI systems. Such a setup can be used in an attempt to sidestep theoretical considerations on the cognitive power of Machine Learning algorithms. Instead, an example is given how the well-established experimental testing of intelligence in animals could be translated to the described AI system. While the published work-in-progress state of the implementation allows similar experiments of multiple interacting virtual robots to be conducted and a theoretical outline for future tests is sketched, a lot of further research will be required before a robot can demonstrably recognize itself in a mirror.

On Overcoming the Gap between Industry and Academic Research in the Field of Music Technology
(Editorial Universitat Politècnica de València, 2023-01-10) Pöpel, Cornelius; Egbert, Jürgen
[EN] The field of industrial music technology, as well as academic research on music technology, strives for a high innovation potential and depends on it. Therefore, it would make a lot of sense if both areas were in an intensive exchange and cooperative collaboration. In the experience of the two authors, this is the case only to a very small extent. In this paper, observations of islands in research and development are presented. Actions are shown with which attempts were made to establish the transfer between the two areas. On the basis of the experience of the authors where this has more or less worked, it is analysed which factors are decisive for the fact that it is still extremely difficult to establish the transfer. In view of these factors, suggestions are made as to how a better degree of transfer can be achieved in the future

Soft Matter Physics Can Set Biological Clock of Industrial Food Science and (Bio)Technology
(Editorial Universitat Politècnica de València, 2023-01-10) Tekiner, İsmail; Knoblauch, Anke; Özatila, Bahar; Ay, Murat
[EN] Tom McLeash (2005), Professor of Natural Philosophy, says that “in science nothing stays the same. This is true not only at the level of discoveries, experiments, and theories, but also for the coherent structures and disciplines of the scientific community itself. A fascinating recent example has been the emergence of the field of ‘soft matter’ from a recognition that problems in polymer science, colloid science, liquid crystals, surfactant systems, foams, and even biological materials must draw on the same experimental and theoretical tools to make progress.” In this paper, we aim to highlight the concept of soft (condensed) matter physics and its association with industrial food science and (bio)technology within the scope of a new term “food physics”.

Potential Usages of Virtual Reality in Design Research and Practice. A Review
(Editorial Universitat Politècnica de València, 2023-01-10) Stadler, Sebastian
[EN] Besides application fields such as entertainment and marketing, the technology of Virtual Reality is also applied in research and practice, including domains such as automotive, architecture, and construction. Furthermore, VR has been utilized for several activities in design practice and design research. However, the impact of this technology on design as a profession remains to be investigated. Thus, in the present study, an integrative literature review is presented to investigate the potential impact of Virtual Reality on design research and design practice. The findings indicate potential advantages on different levels. VR has the potential to enhance problem identification due to laboratorial environments and to foster co-creation due to enhanced motivation and the establishment of synergies between the involved stakeholders. Furthermore, it supports prototyping activities due to its capabilities for realistic scaling and perspectives. And lastly, VR has proven to be advantageous for design evaluations and reviews due to its visualization and immersion potential. Drawbacks of using VR for design research and practice involve technical limitations such as restricted field of view, limited performance, but also aspects such as missing accuracy for prototyping and the absence of haptic feedback. Future work will involve an extended review involving further literature and application domains.
