  abstract     = {{The following paper examines how gamification principles can expand citizen engagement and participatory processes in the Smart City. Smart city data in particular can be communicated excellently via digital media, regardless of location and time, due to the way it is technologically generated, stored and processed. Consequently, it makes sense to develop separate digital visualizations and tools for citizens, which on the one hand explain relevant relationships in a generally understandable way and on the other hand can reduce the high technological complexity. Especially in recent times, new formats of digital citizen participation have been emerging, some of which are specially developed between actors in urban development and media agencies (i.e. ZebraLog, Decidim, etc.). It is not uncommon that also the latest technologies such as VR glasses, digital twins, etc. come to use. But despite all the technological innovation, one of the basic problems of classic participation remains unsolved: The mix of participating citizens does not reflect the diversity of society even remotely. Socioeconomically disadvantaged groups in particular are not sufficiently reached and hence not included; instead, it tends to be the educated middle class that participates "who may be passionate about certain issues and ignore larger issues" (Ampatzidou et al. 2018; Akers 2022). Moreover, digital platforms require the decision to actively access it online. Against the background of this challenge, the two research teams of the Institute for Design Strategies at the University of Applied Sciences and Arts Ostwestfalen-Lippe are trying to link digital Smart City techniques with the potential of gamification by building and testing very simple and analog tools and methods. In these the linked digital data tends to take place much more in the background while the joy of playing with tangible elements could support citizen engagement and behavioural changes in an easier way. This paper looks at a selection of six applied methods and formats that the team has tested in the public spaces of the medium sized city Detmold, Germany, in a completely or partially analog way in 2024. Topics such as urban planning, data security, mobility, climate change and the Smart City itself were discussed in the formats. The methods tested serve as supplementary elements to online participation and as a further development of classic outreach. Categorizations of gamification elements were reviewed for the analysis. In addition, the methods were classified at different levels of participation according to Cardullo and Kitchin based on Arnstein's work. The paper also takes a critical look at the statement that "Many believe that technological advancements in communication will support a bright new era of political engagement and dialogue" (Green 2020) and that digitalization is therefore the panacea for participation. Furthermore, it has been examined how power imbalances can be countered and a more inviting environment for participatory practices can be achieved.}},

  abstract     = {{Securing factory communication to protect corporate data is an important concern in the context of the Industrial Internet of Things (IIoT). Various cryptographic protocols can be used to establish secure communication channels. One of these protocols is the Transport Layer Security 1.3 (TLS 1.3) protocol. A key component of the TLS handshake protocol is the Elliptic Curve Diffie-Hellman Key Exchange (ECDHKE), a public key cryptosystem used to exchange keys over insecure channels which can be based on a number of standardized elliptic curves. A special form of elliptic curves are Montgomery curves which are advantageous compared to more traditional Weierstrass curves due to their fast arithmetic. This is especially important when the ECDHKE is performed on embedded devices and in time-critical situations. In this work, the performance of ECDHKE implementations using standardized Montgomery curves Curve25519 and Curve448 included in the wolfSSL library are evaluated on an embedded 32-bit STM32L476RG Nucleo development board designed by STMicroelectronics. The benchmark results show that using Curve25519 with around 220ms for the key pair generation and the key agreement respectively is approximately 75% faster than using Curve448 with around 900ms for each of the algorithms, which can be attributed to their differing security levels. These results suggest that the algorithms might not be fast enough for time critical situations.}},

  abstract     = {{Stachybotrys chartarum is a toxigenic fungus that is frequently isolated from damp building materials or improperly stored forage. Macrocyclic trichothecenes and in particular satratoxins are the most potent mycotoxins known to be produced by this fungus. Exposure of humans or animals to these secondary metabolites can be associated with severe health problems. To assess the pathogenic potential of S. chartarum isolates, it is essential to cultivate them under conditions that reliably promote toxin production. Potato dextrose agar (PDA) was reported to be the optimal nutrition medium for satratoxin production. In this study, the growth of S. chartarum genotype S strains on PDA from two manufacturers led to divergent results, namely, well-grown and sporulating cultures with high satratoxin concentrations (20.8 ± 0.4 µg/cm2) versus cultures with sparse sporulation and low satratoxin production (0.3 ± 0.1 µg/cm2). This finding is important for any attempt to identify toxigenic S. chartarum isolates. Further experiments performed with the two media provided strong evidence for a link between satratoxin production and sporulation. A comparison of three-point and one-point cultures grown on the two types of PDA, furthermore, demonstrated an inter-colony communication that influences both sporulation and mycotoxin production of S. chartarum genotype S strains.}},

RPP has considerably increased the rate of production and the possibility of manufacturing prototypes in the fields of electrical, optical, and mechanical engineering. The manufacturing of optical prototypes including spherical, aspheric, and special kinds of lenses and lens arrays has reformed the fabrication of optical components. In this paper, specifically designed lens array prototypes for application in visible light communication (VLC) are introduced. These lens array prototypes are manufactured using the stereolithography apparatus (SLA) process. These lens arrays are designed to achieve optimal transmission of the light beam for VLC systems. One of the prototypes from the lens arrays contains primarily four spherical lenses and one thicker convex lens and the other contains one fresnel lens as a substitute for thicker convex lens. These lens arrays are further post-processed to achieve the required transparency. These lens array prototypes are tested using laser and LEDs. The ON-OFF keying modulated light beam was transmitted through the lens array at the sender side and focused on the photo-receiver using another lens array at the receiver side which is 200 cm apart. After evaluating these lens prototypes, it can be concluded that with appropriate post-processing and high-resolution stereolithography based manufacturing, a low data rate VLC link can be formed.}},

modulation of illumination devices. However, to increase the performance, typically, beam-forming measures are
taken creating pencil beams, thus contradicting the illumination purpose. In order to optimize the performance

examined. Illumination LEDs with standard drivers and without beam-forming show limited applicability for
communication purposes as they are not optimized for the necessary switching capability (f  11 MHz) and
coherence. Methods to enhance the electrical current by pre-equalisation, biasing, carrier sweeping and current
shaping are examined in respect to the illumination LED's communication performance. A novel driver scheme
is derived which achieves considerably higher switching frequencies (f  100 MHz) without employing beamforming
at the illumination LED. This driver is able to obtain a data rate of up to 200 Mbit/s at a distance of
3.2 m, using on-o keying (OOK) modulation technique. Therefore, it is feasible to apply the LED driver by

  abstract     = {{Industrial wireless communication in license-free spectrum bands such as the 2.4-GHz-ISM band suffer from motion and multipath effects, which cause a high time- and frequency-variant channel attenuation. Additionally, mutual interference from heterogeneous wireless technologies limits real-time capabilities of industrial wireless technologies. Therefore, performance validations of industrial wireless technologies within appropriate industrial wireless environments are necessary. In this paper, we present the first raw measurement data set publication of an industrial wireless environment characterization in a data repository for free public access to enable transparent industrial wireless technology validation and to enhance their comparability. We characterize the whole license-free 2.4-GHz-ISM band with a time resolution of 110 μs and a frequency resolution of 1MHz in a coexistence scenario with four antennas obstructed by robot arm movements. Additionally, the frequency and time variance of the measured channel attenuations are analyzed.}},

The reduction of wires and connections can potentially ease the modularity and reconfigurability of industrial production installations, if the data communication offers a sufficiently high robustness against influences from the DC power transmission. This part of our research focuses on the necessary electrical adaptations between data and power circuitry and evaluates interference scenarios that are common for industrial fieldbus installations.}},

RoomXT virtually extends a user's physical environment by providing a “life-like” communication channel for informal and spontaneous interactions. We use a wall-sized display together with head-tracking and 3D rendering to achieve visual contiguity between the real and a virtual environment. As one possible application of this system, we set up a remote dining situation for two users. The dinner table is visually extended into the virtual environment in which a live video stream of the dining partner is shown. Great care was taken in regard to the aesthetic and device-free integration into the living room. First impressions of potential users support the validity of our design decisions.}},

The system uses a wall-sized display that is seamlessly integrated into a living lab, to create a 'life-like' video communication experience. In order to demonstrate the potential of this approach, we conducted a living lab study comparing the developed prototype with a desktop-based system. A special video communication application, which enables spatially separated users to have a joint dinner experience, served as a common basis for the different test conditions. Results of the study show that the overall concept of roomXT was well eceived by users of a wide age range and that the developed prototype system seems to be preferred to commercially available video communication solutions with respect to the tested quality dimensions.}},

The work was motivated by recurring usability problems identified in evaluations of state-of-the-art awareness systems. Based on these findings, it is argued that the limited success of existing systems is mostly caused by conceptual shortcomings, which can be overcome by adhering to a set of design recommendations elaborated in this paper. To demonstrate the validity of this argumentation, the development and evaluation of an ambient awareness system is illustrated.}},

The investigations were carried out in harsh industrial environments in the presence of parasitic machine emissions, intentional and unintentional interferers. The air paths were obstructed by moving machine parts and daily work traffic. As a result we can conclude, that wireless automation systems based on Bluetooth technology are extremely reliable due to their inherent system features like adaptive frequency hopping at high operating frequencies, error detection and correction. Neither parasitic machine emissions nor other radio systems or transceiver movements can impair the transmission, as long as distances are below 30 m}},

The issues are: 1) supporting informal communication and atmosphere in organisations, 2) the role and potential of ambient displays in future work environments, and 3) the combination of mostly static artefacts that are integrated in the architectural environment with mobile devices carried by people. Our results can be considered as steps towards the design and realization of what we call “social architectural spaces” in the context of future work environments. These environments will be populated with a range of different smart artefacts that are designed to facilitate awareness and notification as well as informal communication. We address a range of spaces in office buildings including public spaces, e.g., in the hallway, the foyer, and the cafeteria that have not been the focus of research so far. In particular, we present two artefacts: the Hello.Wall, a wall-size large ambient display, and the ViewPort, a mobile handheld device. They are interacting with each other via wireless networks and different types of sensing technology. The artefacts and the software were developed in the EU-funded “Disappearing Computer”- project “Ambient Agoras: Dynamic Information Clouds in a Hybrid Worlds”.}},
