abstract = {{Numerous single-track railway lines are currently disused due to economic factors. These lines could potentially be reactivated by small vehicles that utilise only a single rail, enabling bidirectional operation simultaneously. The MONOCAB is such a compact monorail vehicle, stabilised by a system of control moment gyroscopes (CMGs) and a laterally movable, controllable trim mass. Despite their potential, there is currently a lack of comparative references for MONOCABs in relation to other vehicles. In the context of mechanical design and construction, interdependencies with roll stabilisation occur. Of particular concern are torsional effects, which can significantly impact stability. This study investigates the structural dynamics of monorail vehicles with a focus on the influence of gyroscopes. Gyroscopic systems play a significant role in the behaviour of such vehicles, affecting stability, control and response to external disturbances. Through a comprehensive approach encompassing analytical modelling, numerical simulations, and experimental validation, the interactions between the vehicle's structure and gyroscopic components are explored. The analytical considerations are validated via experimentally derived frequency responses utilising a full-scale monorail vehicle. The results of this study have implications for various fields, such as transportation, robotics and aerospace engineering.}},

Regarding such a vehicle, there is currently no reference in comparison with other vehicles and no experimental experience or the like. To ensure the functionality and safety of the vehicle even before its realization, a model-based design is carried out for development, analysis, optimization and testing. This paper is focused on the co-simulation of such a vehicle that is controlled by a longitudinal control. In order to take into account the complex interaction between the longitudinal dynamics and the running gear, the entire system must be considered here including the wheel/rail interaction. Co-simulations are performed considering both the mechanical model of the vehicle and the control of the longitudinal dynamics of the overall system. The simulation results show that functionality and safe operation can be ensured by the vehicle longitudinal controls. As a result, the simulation and the measurement of the real system show a good match. By means of HIL and co-simulations, function tests could be shifted to earlier development stages, in order to accelerate the overall development.}},

abstract = {{To evaluate the suitability of an analytical instrument, essential figures of merit such as the limit of detection (LOD) and the limit of quantification (LOQ) can be employed. However, as the definitions k nown in the literature are mostly applicable to one signal per sample, estimating the LOD for substances with instruments yielding multidimensional results like electronic noses (eNoses) is still challenging. In this paper, we will compare and present different approaches to estimate the LOD for eNoses by employing commonly used multivariate data analysis and regression techniques, including principal component analysis (PCA), principal component regression (PCR), as well as partial least squares regression (PLSR). These methods could subsequently be used to assess the suitability of eNoses to help control and steer processes where volatiles are key process parameters. As a use case, we determined the LODs for key compounds involved in beer maturation, namely acetaldehyde, diacetyl, dimethyl sulfide, ethyl acetate, isobutanol, and 2-phenylethanol, and discussed the suitability of our eNose for that dertermination process. The results of the methods performed demonstrated differences of up to a factor of eight. For diacetyl, the LOD and the LOQ were sufficiently low to suggest potential for monitoring via eNose. }},

In literature, different classifications of the tasks and functions of production planning and control (PPC) exist, of which one is the German Aachen PPC model. This research aims to identify and classify current Industry 4.0 approaches for planning and controlling production processes and to reveal researched and unexplored areas of the model.
Design/methodology/approach: In an exploratory literature review, we review and classify 48 publications on a full-text basis with the Aachen PPC model's tasks and functions. Two cluster analyses reveal researched and unexplored tasks and functions of the Aachen PPC model. Additionally, we give a summary of each reviewed publication.
Findings: We propose a cyber-physical PPC architecture, which incorporates current Industry 4.0 technologies, current optimization methods, optimization objectives, and disturbances relevant for realizing a PPC system in a smart factory. Current approaches focus on the in-house PPC, particularly on the control using real-time information from the shop floor. We propose future research directions for the unexplored tasks and functions of the Aachen PPC model.
Research limitations/implications: The selection of search terms and the texts' interpretation is based on an individual assessment. The revelation of unexplored tasks and functions of the Aachen PPC model might have a different outcome if the search term combination is parameterized differently.
Originality/value: Using the Aachen PPC model, which holistically models PPC, the findings give comprehensive insights into the current advances of tools, methods, and challenges relevant to planning and controlling production processes under Industry 4.0.}},

Especially industrial applications ask for high uptimes and a stable voltage supply, which are both at stake in a power grid dominated by renewable generation. DC-MGs overcome these drawbacks by balancing energy distribution and power demand locally. For the planning and design of these grids a systemic approach is needed, due to the fact that many components are interacting. The task arises of structuring the knowledge available for individual technologies in an overall design framework. For this purpose, current state-of-the-art design processes are discussed in this article. These processes are mapped into the context of the requirements in an industrial environment. The findings are transferred to the design of industrial DC networks. Finally, a complete design process for DC-MGs is derived, which is proposed as a basis for the development of tools.}},

abstract = {{Pasteurization is a crucial processing method in the food industry to ensure the safety of consumables. A major part of contemporary pasteurization processes involves using flash pasteurizer systems, where liquids are pumped through a pipe system to heat them for a predefined time. Accurately monitoring the amount of heat treatment applied to a product is challenging. This monitoring helps ensure that the correct heat impact (expressed in pasteurization units) is applied, which is commonly calculated as a product of time and temperature, taking achievability of the inactivation of the microorganisms into account. The state-of-the-art method involves a calculation of the applied pasteurization units using a one-point temperature measurement and the holding time for this temperature. Concerns about accuracy lead to high safety margins, reducing the quality of the pasteurized product. In this study, the applied pasteurization level was estimated using regression models trained with NIR spectroscopy data collected while pasteurizing fruit juices of different types and brands. Several conventional regression models were trained in combination with different preprocessing methods, including a novel prediction outlier detection method. Generalized juice models trained with the concatenated data of all types of juices demonstrated cross-validated scores of RMSECV ∼2.78 ± 0.09 and r2 0.96 ± 0.01, while separate juice models displayed averaged cross-validated scores of RMSECV ∼1.56 ± 0.04 and r2 0.98 ± 0.01.

The calves have an immature immune system as they lack immunoglobulins (Igs). Subsequently, the supply of good quality bovine colostrum is required.

Bacterial contamination can contain a variety of human pathogens or high counts of spoilage bacteria, which has become more challenging with the emerging use of bovine colostrum as food and food supplements. There is also a growing risk for the spread of zoonotic diseases originating from bovines. For this reason, processing based on heat treatment or other feasible techniques is required.

Existing emulation concepts either rely on the differentiation of velocity feedback or utilize measured quantities of the DUT. The emulation method proposed in this paper uses acceleration feedback to control the torque of the load drive. It does not require any measured quantities of the DUT which allows a simple replacement of the DUT’s motor and/or inverter without the need of any conceptual changes. Based on a physical model, the emulation method is derived analytically and analyzed numerically for the emulation of one-mass-systems. The stability and emulation quality is evaluated considering two controller architectures. Finally, experiments are conducted and compared to numeric simulations to test the correct emulation.}},

Special attention is given to the surface quality in terms of surface roughness and its optimization directly in the Selective Laser Melting process. This article presents the possibility for a remelting process of the SLM parts as a way to optimize the surfaces of the produced parts. The influence of laser remelting on the surface roughness of the parts is analyzed while varying machine parameters like laser power and scan settings. Laser remelting with optimized parameter settings considerably improves the surface quality of SLM parts and is a great starting point for further post-processing techniques, which require a low initial value of surface roughness.}},

abstract = {{The purpose of this paper is to convey a thorough understanding of the governance-related determinants and financial consequences of carbon performance and disclosure. Its motivation lies in the increasing global political, social, academic as well as practical importance of managing and reporting on carbon-related issues. Methodologically, we employ a systematic literature review. Thus, we identify 73 quantitative peer-reviewed empirical studies in this field and categorize them according to a legitimacy-theory-based framework. Our four main contributions offer new insights into this emerging research field and provide guidance for the development of new research models: First, we help future researchers to structure this emerging field of research with respect to the interactions of the phenomenon itself (carbon performance vs. disclosure), its determinants (country- and firm-related governance), and its financial consequences (value relevance, information asymmetry, financial performance, and cost of capital). Second, we provide a comprehensive overview of variables and proxies used in the studies and list their main statistical effects, which facilitates building novel models. There are indications that 1) board composition positively influences both carbon performance and disclosure, 2) carbon performance and carbon disclosure are positively connected, 3) carbon disclosure reduces information asymmetry, and 4) carbon performance increases financial performance. Third, we develop a research agenda with concise suggestions for future studies. Fourth, we argue that due to the under-theorization of concepts the comparability of included studies is challenging, this research field may be characterized as a vibrant field for extensive future research.

An executable skill-metamodel therefore describes the methodological functionality which is implemented by using OPC UA due to its vendor independence as well as built-in services and information model.

abstract = {{Properly handled fish is usually marketed as “fresh fish” until day 10 after fishing. About 40% of the total fishery that is used for direct human consumption is marketed in fresh form stored at temperatures up to +2 °C. Currently, there are no validated methods available for controlling the recommended period of storage. Apart from being a potential source for food fraud, spoiled fish represents a major source of foodborne illnesses and intoxications.
In this study, a rapid MALDI-TOF mass spectrometry based screening method was developed using the vitreous fluid of fish eyes as specimen for the examination of different days of storage. The vitreous fluid was collected from n = 100 freshly fished brown trouts at day 0, 3, 7, 9, and 11 post mortem (n = 20 brown trouts each day of examination). The samples were immediately measured by MALDI-TOF mass spectrometry in linear positive mode (mass range m/z 2000–20,000 Da). For quality assurance the experiment was repeated with a set of brown trouts (n = 100) originating from the same fish farm and with brown trouts (n = 100) originating from a different fish farm. For specificity testing rainbow trouts (n = 10) were examined accordingly. All obtained mass spectra were processed by means of MALDI Biotyper OC 3.1 and ClinProTools 3.0 software.
The MALDI Biotyper approach showed limited applicability for the identification of the time of storage. However, it was suitable to reliably discriminate between the closely related species brown and rainbow trout. Processing by ClinProTools revealed four crucial mass peaks (m/z 2594 Da, m/z 4857 Da, m/z 4879 Da, m/z 4899 Da) which enabled a reliable differentiation between day 0 and 3, 7, 9, 11 (rate of correct identification > 90%) as well as the differentiation between day 3 and 7, 9, 11 (rate of correct identification > 72%). However, this approach showed limited applicability within the end of the tested period of storage when comparing between day 7, 9, or 11.}},

abstract = {{This paper introduces an efficient modular solution kit for intralogistic drives, which reduces the total energy consumption of all drives in an automated warehouse by more than 15%. The reduction of energy consumption results from the interaction of optimized components (motors, control techniques and regeneration units), which are described in detail in this paper. Different motor concepts like the induction motor, the synchronous reluctance motor and the permanent magnet synchronous machine are compared according to the special requirements for intralogistics applications. Different control techniques are presented in order to achieve sensorless and efficient-optimal operation of these motors. The sensorless control technique uses signal injection to detect the rotor position sufficiently exact also in case of speed near standstill. Efficient-optimal operation is achieved by reducing the motor current with regard to the torque (MTPA-control). Furthermore this paper introduces a regeneration unit that can be connected between the DC link of frequency inverters and the mains to feed back regenerative energy. The regeneration unit consisting of a buck converter, a synchronous inverter and a line-filter can work in parallel to commonly used uncontrolled rectifiers. Its functioning is shown with the help of measurement results of a 1kW laboratory prototype. The last section shows a demonstrator in which a conventional conveyer system (with induction motor and braking resistor) is compared with an optimized one using the presented components. Power versus time measurements show specific energy savings resulting from the interaction of the optimized components.}},

abstract = {{This paper is aimed to discuss current research using data mining techniques and industry statistics in production environments. The general research approach is based on the idea of using data mining processes and techniques of industry statistics to find rare and hidden patterns behind failures of complex components. A case study will be applied to illustrate how the technique is carried out and where the limits of this approach occur. The case study deals with a component supplier of printing machines, which received an increasing number of client complaints, all related to one distinct problem. The observed failures seem to occur only among clients with very high quality standards. The affected component undergoes a very complex production process with several steps in different departments. Every single production unit records data information from multiple process variables and at different points in time. In the beginning there was no understanding of the failure causes in production at all. Therefore a huge amount of production data had to be analyzed to find the pattern that discloses the failure.
The data mining process starts with a first step in which the given data sets are prepared and then cleaned. Followed up by building a prediction model. The aim is to detect the root causes for failures and to predict potential failures in affected components. This paper shows how to use data mining to get the answer on pressing production failures.

For example, a space can be smart by having and exploiting knowledge about the persons and artifacts currently situated within its borders.In contrast, a people-oriented, empowering smartness approach places the empowering function in the foreground by assuming that smart spaces make people smarter. This approach empowers users to make decisions and take actions as mature and responsible people.Although in some cases it might be more efficient if the system doesnýt ask for a userýs feedback and confirmation at every step in an action chain, the overall design rationale should aim to keep the user in the loop and in control whenever possible.}},
