We consider prior knowledge from systems of linear partial differential equations together with their boundary conditions. We construct multi-output Gaussian process priors with realizations in the solution set of such systems, in particular only such solutions can be represented by Gaussian process regression. The construction is fully algorithmic via Grobner bases and it does not employ any approximation. It builds these priors combining two parametrizations via a pullback: the first parametrizes the solutions for the system of differential equations and the second parametrizes all functions adhering to the boundary conditions.}},

Compared to the prototyping application, the production of end-use parts demands a higher level of repeatability and process quality. To achieve this, increased knowledge is required about the influence of various process parameters on the part characteristics and the parameter interrelations. Design of Experiment methods can be applied to gain knowledge on the process behavior, but the applicability of different DoE methods for AM processes has to be validated. This paper describes the application of a definitive screening design for the identification of influencing parameters in Laser Powder Bed Fusion of CoCrW alloy. The impact of various hatch parameters on the part porosity is analyzed. The experimental setup and results are described. The results are validated in an additional test series, comparing the part quality achieved by parameter-sets obtained by different optimization approaches. Furthermore, the correlation of the porosity towards mechanical properties is investigated. Finally, the opportunities and limitations of the method are discussed.}},

This research is based on the idea to achieve great cost and operational benefits especially in the field of tool making for injection molding by combining traditional and additive manufacturing in one process chain. 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.}},

A big data platform (BDP) instantiates the pipelines and monitors the CPPS performance for further evaluation through the cognitive module. Thus, the cognitive module is able to select feasible and robust configurations for process pipelines in varying use cases. Furthermore, it automatically adapts the models and algorithms based on model quality and resource consumption. The cognitive module also instantiates additional pipelines to evaluate algorithms from different classes on test functions. CAAI relies on well-defined interfaces to enable the integration of additional modules and reduce implementation effort.

abstract = {{n recent decades, the demand for palm oil has constantly increased and with it the cultivation of oil palms. After a period of 25 years, the oil yield of the palm trees decreases and they are felled. The trees are cut into pieces and remain on the plantations. However, due to their high moisture and sugar content, fungi and molds cause problems for replanting. The use of the wood for the timber industry is difficult due to its structural characteristics. Biotechnological processes use microorganisms to produce relevant industrial products. The basis for each process is a culture medium that contains all necessary nutrients, especially carbohydrates. The culture medium makes up a high percentage of the costs, so alternative, cheaper substrates are preferred. In this review, we show and compare different analyses of the sap mechanically pressed from the oil palm trunk regarding its sugar and nutrient content. The total sugar concentration in the palm sap varies between 16.97–140 g L−1 and it is mainly composed of glucose, fructose, and sucrose. The comparison with common nutrient media and the results of fermentation processes already carried out on a laboratory scale show that palm sap offers great potential as a fermentation medium for biotechnological conversion into industrially relevant products. }},

abstract = {{Due to the fact that modern diesel engines require very well-defined fuel properties to ensure high efficiency, low emissions and a long durability, the fuel properties and their determination methods have to be standardized. Most diesel fuel standards allow a certain volume fraction of biodiesel that can be blended to fossil diesel fuel. Biodiesel consists of saturated and unsaturated fatty acid methyl esters (FAME) which are more susceptible to oxidation compared to fossil diesel fuel. Oxidation products formed by autoxidative processes can lead to higher emissions, a higher corrosiveness, fuel filter blocking, clogging of fuel injectors, the formation of deposits in the entire fuel system and a decreasing lubricity [1]. Therefore, oxidation needs to be prevented by the addition of oxidation inhibitors. These antioxidants are consumed during storage, resulting in partial loss of their efficiency against oxidative stress. After this induction period all antioxidants have been consumed and harmful oxidation products can be formed. For the determination of the long-term storage stability of diesel fuels rapid oxidation stability test methods were developed and defined by standards. In Europe, the most important determination methods are the Rancimat method and the rapid small scale oxidation test (RSSOT). Both methods differ in the construction of the measurement device and various parameters. However, it is not clear whether the results of both methods can be correlated in general. Due to the importance of the oxidation stability, we here describe the results of a literature research that was carried out using 17 literature sources. Possible correlation factors between the Rancimat and the RSSOT method were analyzed, showing that a universal correlation cannot be found. In contrast, a comparison of individual series of measurement, e.g. with the same antioxidant at various concentrations, can show a good correlation between the methods.}},

abstract = {{The need for new bio based drop-in components for combustion engine fuels and the availability of sustainable glycerol from biodiesel production has focused attention on isopropylidene glycerol (solketal). The present study investigates the physical and chemical behavior of solketal in ternary blends with diesel fuel/biodiesel. Hydrotreated vegetable oil (HVO) was used as renewable non-polar aliphatic diesel fuel substitute in biodiesel/ solketal blends. HVO can be considered a prototype for other non-polar fuel components such as paraffinic fuel streams from Fischer-Tropsch or BtL processes. Surface tension, permittivity and aging behavior were analyzed. Furthermore, the cetane number (CN) and the viscosity was determined. Permittivity reflects the polarity of blends and their components with its change being an indicator of loss of physical and chemical stability. The antioxidant triphenyl phosphorothioate (TPPT) was also tested in some blends. The biodiesel blends B20, B30 and B40 enables single phased diesel fuel or HVO with varied solketal content (2 and 10%) at a constant biodiesel amount. No effect of solketal on fuel aging was observed. However, HVO-containing blends tend to lower the thermo-chemical stability relative to diesel fuel.}},

abstract = {{Human Factors in Hypertext 2021 (HUMAN'21) is the 4th workshop in this series. It is sponsored by ACM SIGWEB and is associated to the ACM Conference on Hypertext and Social Media 2021, which took place between August 30th and September 2nd as a virtual event. HUMAN'21 took place on August 30th-the conference's workshop day.
This year's workshop is held in a difficult time: the global Corona pandemic makes attending meetings or traveling risky for our health. It almost seems as a contradiction to the 2019 ACM Hypertext motto "tear down the wall". However, today's digital media enables us to communicate over distance or even attend larger meetings online. This also opens the question about the role of hypertext as a medium for communication-a perfect topic match for the HUMAN workshop series, which has a user-centric focus on hypertext.
The user-centric view not only includes user interfaces and interaction, but also discussions about hypertext application domains. Furthermore, the workshop raises the question of how original hypertext ideas (e.g., Doug Engelbart's "augmenting human intellect" or Frank Halasz' "hypertext as a medium for thinking and communication") can improve today's hypertext systems. As such, the HUMAN workshop also appreciates previous work on hypertext systems. In order to support this, we invite researchers to give demos of vintage hypertext systems. Last year we started with Norman Meyrowitz presenting Intermedia; this year Mark Anderson has been invited to give a demo of Microcosm.}},

They can support the development process of a production machine by avoiding an inadequate layout of components or an erroneous control design. However, the effort for building them is often too high for this purpose (lot size one). An automated model generation can be utilized to overcome the gap between efforts and advantages of dynamic simulations.
This contribution presents an approach for simplifying the dynamic model generation of production machines by using the so-called Asset Administration Shell defined by the initiative Platform Industrie 4.0. The Asset Administration Shell was developed to aggregate all data necessary for maintaining the product across its life cycle. This includes component data and models as well as structural information about a machine. The generation process is performed by using the common FMI standard and a two-step procedure which allows the linkage of different simulation tools. The model generation is demonstrated by an example layout of a machine's internal direct current grid.}},

Typical test setups consist of two mechanically coupled motors, one of which is the Device Under Test (DUT) while the other is used as a load drive for emulation. 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.}},

abstract = {{Today DC offers far-reaching advantages over AC. Therefore, many devices have been equipped with an internal DC link for many years. In the field of energy supply, the use of DC technology is also growing and is state of the art in offshore, high-voltage, vehicle, data center applications. The spread of industrial open DC grids is currently starting and is completely different due to the requirements: The DC grid is highly dynamic. This means that the oscillation behavior must be investigated. The paper describes the characteristics and the limits of stability for an open industrial DC grid.}},

abstract = {{An open industrial DCgrid for energy supply has many benefits. Also new challenges arise by coupling the DClink capacitors of all devices, e.g. inverters. This paper presents the effects of component failures causing short circuit faults in combination with electrically coupled and charged DClink capacitors. Resulting energy flows are shown, which arise in the DCgrid in case of faults. In addition, measurements of short circuit tests and two solutions are shown, which enable the safe and simple operation of an open industrial DCgrid.}},

Alle hessischen Kläranlagen ab einer Ausbaugröße von 1.000 EW müssen nun Schritt für Schritt niedrigere Phosphor-Grenzwerte einhalten. Durch eine Halbierung der Phosphor-Einträge sollen in allen Fließgewässern die Phosphat-P-Konzentrationen auf einen unkritischen Wert von unter 0,07 mg/l PO4-P reduziert werden. Im Rahmen der Bestandsaufnahme und Erfolgskontrolle werden in dieser Studie Betriebsergebnisse und Erfahrungen zur Phosphorelimination auf mittelhessischen Kläranlagen systematisch ausgewertet und evaluiert. Die Daten und Erkenntnisse der betrachteten Kläranlagenwerden allgemein zusammengestellt und emissionsseitig ausgewertet.}},
