description: Electronic appliance manufacturers are facing the challenge of frequent product orders. Based on each product order, the assembly process and workstations need to be planned. An essential part of the assembly planning is defining the assembly sequence, considering the mechanical product’s design, and handling of the product’s components. The assembly sequence determines the order of processes for each workstation, the overall layout, and thereby time and cost. Currently, the assembly sequence is decided by industrial engineers through a manual approach that is time-consuming, complex, and requires technical expertise. To reduce the industrial engineers’ manual effort, a Computer-Aided Assembly Sequence Planning (CAASP) system is proposed in this paper. It compromises the components for a comprehensive system that aims to be applied practically. The system uses Computer-Aided Design (CAD) files to derive Liaison and Interference Matrices that represent a mathematical relationship between parts. Subsequently, an adapted Ant Colony Optimization Algorithm generates an optimized assembly sequence based on these relationships. Through a web browser-based application, the user can upload files and interact with the system. The system is conceptualized and validated using the CAD file of an electric motor example product. The results are discussed, and future work is outlined.

description: For manufacturing of large parts made of lightweight materials like aluminum, fiber reinforced plastics or composites for example for the frame in aerospace or automotive industries more and more industrial robots are used. Their main challenge is the low stiffness compared to conventional machine tools resulting in positioning errors. A lot of research is done in order to compensate trajectory errors and enable them for milling operations, which result from the weaknesses in the kinematic. Nevertheless, dynamic properties influence the process stability, which cannot be compensated with the robot control as the dynamic of the joint, and the cycle time of the robot control is limited. Therefore, different robot designs are presented and compared regarding their stiffness, dynamic properties and costs. Afterwards the main weaknesses of the selected design were identified and used for optimization to reduce the deflection and positioning errors during cutting operation. Furthermore, the machine tool structure was topologically optimized for different poses to achieve a higher accuracy in the working space.

description: How do academics become professors? This paper considers the making of ‘professor’ as a subject position through which academics are acknowledged in both organizational contexts and disciplinary fields. The paper examines social processes of recognition in 145 appointment procedures for professorships in the discipline of history at sixteen German universities between 1950 and 1985. Based on an analysis of over 1500 documents from archived appointment records, I investigate how academics are acknowledged as professorial in appointment procedures. The procedures invoked both (1) processes of judgement, in which worth and qualities are attributed to candidates, and (2) processes of legitimation, in which said judgements are stabilized and made acceptable. Using insights from the sociology of valuation and evaluation, this paper sheds light on the fundamental processes of recognition and valorization in academia. The findings contribute to the sociology of scientific knowledge and science and technology studies, which have concentrated on academic recognition in the realm of research, but paid less attention to such recognition in organizational contexts. Complementing this literature, the paper allows for a more general understanding of ‘professor’ as a focal academic subject position.

description: In this paper, a cell-based smoothed finite element method with discrete shear gap technique for triangular ele- ments is employed to study the linear flutter characteristics of functionally graded material (FGM) flat panels. The influence of thermal environment, the presence of a centrally located circular cutout and the aerodynamic damping on the supersonic flutter characteristics of flat FGM panels is also investigated. The structural for- mulation is based on the first-order shear deformation theory and the material properties are assumed to be temperature dependent and graded only in the thickness direction according to power law distribution in terms of the volume fraction of its constituent materials. The aerodynamic force is evaluated by considering the first order high mach number approximation to linear potential flow theory. The formulation includes transverse shear deformation and in-plane and rotary inertia effects. The influence of the plate thickness, aspect ratio, boundary conditions, material gradient index, temperature dependent material properties, damping, cutout size, skewness of the plate and boundary conditions on the critical aerodynamic pressure is numerically studied.

description: The operation of CNC milling is expensive because of the cost-intensive use of cutting tools. The wear and tear of CNC tools influence the tool lifetime. Today’s machines are not capable of accurately estimating the tool abrasion during the machining process. Therefore, manufacturers rely on reactive maintenance, a tool change after breakage, or a preventive maintenance approach, a tool change according to predefined tool specifications. In either case, maintenance costs are high due to a loss of machine utilization or premature tool change. To find the optimal point of tool change, it is necessary to monitor CNC process parameters during machining and use advanced data analytics to predict the tool abrasion. However, data science expertise is limited in small-medium sized manufacturing companies. The long operating life of machines often does not justify investments in new machines before the end of operating life. The publication describes a cost-efficient approach to upgrade legacy CNC machines with a Tool Wear Prediction Upgrade Kit. A practical solution is presented with a holistic hardware/software setup, including edge device, and multiple sensors. The prediction of tool wear is based on machine learning. The user interface visualizes the machine condition for the maintenance personnel in the shop floor. The approach is conceptualized and discussed based on industry requirements. Future work is outlined.

description: The transport spot rate in trucking logistics is an important factor for market participants in the recycling industry. Knowledge about the current spot rate is essential for operational decision-making in price negotiations between brokers and shippers. Due to the characteristics and dynamics of the industry, this task is particularly challenging. So far, businesses mainly rely on traditional calculation methods combined with their own expertise in price negotiations. The growing amount of existing business and market data may enable companies to take advantage of data-driven decision processes. However, the resulting volume of data and required effort for analysis do not match the fast pace of daily business. To improve current forecasting practices, this paper conducts a comparative study of machine learning (ML) approaches for shipment-specific spot rate prediction. For this, the paper builds on the experience and database of a small broker in the recycling industry in Northern Germany and complements it with external market information. The study shows the ability of ML to internalize underlying patterns between spot rates and market data. During the use case the CRISP-DM framework is followed to select the most appropriate features and train multiple ML algorithms. Several metrics are applied to determine the most accurate model for spot rate prediction. Results indicate that especially the ML-algorithm Random Forest shows considerable potential to provide brokers in the recycling industry with more reliable spot rate assumptions. Therefore, future implementation of ML approaches in the industry may open up new and beneficial business opportunities. The study paths the way for further research on the predictive potential of ML for prices in transportation with extended and diversified data sets.

description: The set of multiparty correlations that respect all bi-partite principles has been conjectured to be same as the set of time-ordered-bi-local correlations. Based on this conjuncture we find the maximum value of success probability of tri-partite Hardy's correlation respecting all bi-partite physical principles. Unlike in quantum mechanics, the no-signaling principle does not reveal any gap in Hardy's maximum success probability for bi-partite and tri-partite system. Information causality principle is shown to be successful in qualitatively revealing this quantum feature and this result is independent of the conjecture mentioned above.

description: Optical designs for astronomy involve implementation of active optics and adaptive optics from X-ray to the infrared. Developments and results of active optics methods for telescopes, spectrographs and coronagraph planet finders are presented. The high accuracy and remarkable smoothness of surfaces generated by active optics methods also allow elaborating new optical design types with high aspheric and/or non-axisymmetric surfaces. Depending on the goal and performance requested for a deformable optical surface analytical investigations are carried out with one of the various facets of elasticity theory: small deformation thin plate theory, large deformation thin plate theory, shallow spherical shell theory, weakly conical shell theory. The resulting thickness distribution and associated bending force boundaries can be refined further with finite element analysis.

description: Τις τελευταίες δεκαετίες πληθώρα ερευνών έχει διεξαχθεί στον τομέα των πηκτινολυτικών ενζύμων. Τα εν λόγω ένζυμα αποικοδομούν την πηκτίνη με σκοπό την διευκόλυνση της εκχύλισης, την αύξηση της απόδοσης μειώνοντας το ιξώδες, την ενίσχυση αρωμάτων και χρώματος και άλλα, με κύριο στόχο την ευκολότερη διαχείριση της σταφυλομάζας, αλλά κυρίως ένα πιο πλούσιο τελικό προϊόν εμπλουτισμένο με τα εκάστοτε επιθυμητά χαρακτηριστικά. Στο βιβλιογραφικό μέρος της εργασίας αναλύονται εκτενώς οι φαινολικές ενώσεις, οι πηκτίνες, οι πηκτινάσες όπως και γίνεται αναφορά σε ενζυμικά εμπορικά σκευάσματα που έχουν χρησιμοποιηθεί σε αντίστοιχες έρευνες. Στο τρίτο μέρος της εργασίας αναφέρονται τα υλικά και οι ποικιλίες που χρησιμοποιήθηκαν αλλά και οι μέθοδοι και τα πειράματα που διεξήχθησαν. Έπειτα παρουσιάστηκαν τα αποτελέσματα σε μορφή πινάκων ή γραφημάτων και στο τέλος της εργασίας συζητήθηκαν αναλυτικά. Ο στόχος της παρούσας έρευνας είναι η εκτίμηση της επίδρασης δύο ενζύμων πηκτινασών στο γλεύκος. Πιο συγκεκριμένα επιδιώχθηκε η αύξηση της απόδοσης πίεσης με ταυτόχρονη μείωση της συγκέντρωσης φαινολικών και κυρίως ταννινών στον τελικό οίνο. Το πρώτο ένζυμο ήταν μία ασθενώς εκχυλιστική πηκτινάση και το δεύτερο μία ισχυρά εκχυλιστική πηκτινάση. Τρεις ξεχωριστές οινοποιήσεις έλαβαν χώρα. Η πρώτη χωρίς προσθήκη ενζύμου, η δεύτερη με την χρήση του πρώτου ασθενώς εκχυλιστικού ενζύμου και η τρίτη με την προσθήκη του ισχυρά εκχυλιστικού. Το παραπάνω μοτίβο ακολουθήθηκε σε τρεις προσπάθειες. Η πρώτη προσπάθεια με την ποικιλία Pinot noir και η δεύτερη και η τρίτη με μείγμα των ποικιλιών Grenache, Cabernet Franc, Syrah. Έλεγχοι δοκιμές και τεστ πραγματοποιούνταν σε όλη τη διάρκεια της οινοποιητικής διαδικασίας. Σε γενικές γραμμές, το ισχυρά εκχυλιστικό ένζυμο παρουσίασε τα ιδανικότερα αποτελέσματα αν και σε ορισμένες μεταβλητές δεν παρουσιάστηκε στατιστικώς σημαντική διαφορά.

description: PSR J0742-2822 exhibits two distinct emission states that are identified by discrete changes in the observed pulse profile. These changes have previously been shown to correlate with changes in the derivative of the pulse frequency. In this paper, we use observations with the Parkes radio telescope at a centre frequency of 1369 and 3100 MHz to produce high phase resolution polarisation profiles for the two modes and perform a detailed study of the correlation between observed pulse shape and spin-down rate. We find no correlation for at least 200 days prior to a glitch in the pulsar at MJD 55022, following which the correlation becomes strong. This suggests a link between the emission state switching phenomenon and glitch events. We discuss the possibility that emission state switching is driven by the interaction between the magnetosphere and the interior of the neutron star.

description: All-solid-state batteries possess multiple advantages compared to already established battery technologies. Therefore, they are emerging as promising candidates for the sustainable storage of energy and acceleration of electrification in multiple fields. Despite the rapidly growing interest and vast material and cell design research activities, all-solid-state batteries are still in their infancy stage. Both market entry and full exploitation of the storage potential now mainly depend on the development of production technology empowering the large-scale breakthrough. Thereby, the selection of suitable manufacturing routes and development of production processes resulting from the novel components and materials plays a key role. To provide a better understanding and a systematic approach for the analysis of all-solid-state battery production, a holistic Matlab-based SimEvents factory simulation model is presented in this work. It enables the modeling and simulation of all-solid-state battery production scenarios consisting of a certain material choice, process steps, sequence, process parameters, storage capacity, and boundary conditions such as throughput, downtime, and scrap rate. An algorithm automatically performs the evaluation and comparison of the scenarios regarding production-related KPIs such as ramp-up time, capacity utilization, circulating stock, and storage load. In addition, the highly complex and nonlinear dependencies specific for all-solid-state battery production, as well as bottlenecks between the processes, are quantified. As a result, the factory model enables the optimization of manufacturing routes and production processes depending on the product design at a very early stage and the low-level maturity of this new energy storage technology.

description: We obtain constraints on parameters of the Yukawa-type corrections to Newton's gravitational law from measurements of the gradient of the Casimir force between surfaces coated with ferromagnetic metal Ni and from measurements of the Casimir force between Au-coated sinusoidally corrugated surfaces at various angles between corrugations. It is shown that constraints following from the experiment with magnetic surfaces are slightly weaker than currently available strongest constraints, but benefit from increased reliability and independence of systematic effects.The constraints derived from the experiment with corrugated surfaces within the interaction region from 11.6 to 29.2\,nm are stronger up to a factor of 4 than the strongest constraints derived from other experiments. The possibility of further strengthening of constraints on non-Newtonian gravity by using the configurations with corrugated boundaries is proposed.

description: Gears demand increasingly high quality regarding acoustic emissions, surface roughness and lifetime. Therefore, grinding is often the last step in the process chain of gear manufacturing. Grinding wheel grain sizes of 30 micrometers lead to high surface quality and metal bonded CBN-grains allow a high wear resistance and profile stability of the grinding tool. Consequently, an increase of the material removal rates and thus productivity is possible without increasing the thermal load on the workpiece due to the grinding wheels' high thermal conductivity. However, the time and cost intensive dressing process in combination with the high profile requirements for gear grinding prevent the wide application of metal bonded tools for this application. This challenge can be solved using a new dressing approach with geometrically defined cutting edges. Metal bonded CBN-grinding layers have a structure similar to metal-matrix-composites, which can be machined by using the turning operation. The aim of this work is to verify the machinability of metal bonded CBN-grinding layers. In the present work, the chip formation for metal bonded grinding layers is presented.

description: For regenerative purposes, there is a high demand for viable and active cells. A big issue is to have enough viable cells available at any given time. One solution is cryopreservation. In this context, DMSO is used as cryoprotective agent (CPA) along with fetal bovine serum for nutrient supply and stress shielding effects. To use these cells for human clinical studies, it is important to eliminate the serum to prevent foreign immune reactions and virus transmittance and DMSO for its toxic effect. In this study a serum free cryopreservation solution and protocol has been established. The combination of methylcellulose and poloxamer 188 provide the basis for the new CPA. Other additves are -tocopherol, ectoine, prolin and ascorbic acid. The CPAs were examined with 3T3-cells and multipotent stromal cells from the common marmoset monkey (Callithrix jacchus). The cells were preserved with various CPA concentrations, incubation times and different cooling rates. To enable a higher throughput of encouraging conditions a fluorescence microscopy analysis was used. The use of methylcellulose, poloxamer 188 and -tocopherol enables the reduction of DMSO [up to 2.5% (v/v)] and the elimination of serum without viability losses compared to control.

Propagation of the Gravo-Magneto Disc Instability

description: Discs that contain dead zones are subject to the Gravo-Magneto (GM) instability that arises when the turbulence shifts from gravitational to magnetic. We have previously described this instability through a local analysis at some radius in the disc in terms of a limit cycle. A disc may be locally unstable over a radial interval. In this paper, we consider how the local instability model can describe global disc outbursts. The outburst is triggered near the middle of the range of locally unstable radii. The sudden increase in turbulence within high surface density material causes a snow plough of density that propagates both inwards and outwards. All radii inside of the trigger radius become unstable, as well as locally unstable radii outside the trigger radius. In addition, a locally stable region outside of the trigger radius may also become unstable as the gravitational instability is enhanced by the snow plough. For the circumstellar disc model we consider, we find that a quarter of the disc mass is accreted on to the central object during the outburst. The radius out to which the disc is globally unstable is twice that for which it is locally unstable.

description: Geometry measurements are very important to monitor a machine part’s health and performance. Optical measurement system have several advantages for the acquisition of a parts geometry: measurement speed, precision, point density and contactless operation. Measuring parts inside of assembled machines is also desirable to keep maintenance cost low. The Raspberry Pi is a small and cost efficient computer that creates new opportunities for compact measurement systems. We have developed a fringe projection system which is capable of measuring in very limited space. A Raspberry Pi 2 is used to generate the projection patterns, acquire the image and reconstruct the geometry. Together with a small LED projector, the measurement system is small and easy to handle. It consists of off-the-shelf products which are nonetheless capable of measuring with an uncertainty of less than 100 μ m

description: Material Science Methods for Reconstructing the History of Manuscripts  In two sessions, members and associates of the Centre for the Study of Manuscript Cultures (CSMC) in Hamburg present recent collaborative research by scientists from STEM subjects and scholars of the humanities that bridges the gap between humanities and the natural sciences and sheds new light on our understanding of medieval material culture, both within and beyond Europe. How can, for instance, ink and pigment analysis, DNA analysis and multispectral imaging help with the recovery of script, the dating and placing of manuscripts, and the understanding of practices of production and use of manuscripts? What new questions arise from these collaborations? What is the potential, what are the challenges of such fundamentally interdisciplinary research?

description: Currently digitization and Industry 4.0 are some of the most important trends influencing production processes and companies. In a lot of companies Shopfloor Management (SFM) is used to manage production and sustain as well as grow a strategic leadership through lean and efficient processes. Its main goal is to bring focus back to the shopfloor, where value-adding processes are performed, and to increase the connection between managers and shopfloor workers. In light of the aforementioned trend towards continued digitization, this produces a field of tension in which a trend enabling increasingly remote control of production through new digital solutions meets a principle focusing on being on site as well as intensive communication. Combing both aspects can prove to be complex as can be seen by studies showing a wide distribution of SFM in a selection of German production companies, but with exceptionally low usage of digital technology. A significant cause of this is the overwhelming number of possible aspects of Industry 4.0 increasing the difficulty of selecting manageable ideas, aggravated by a lack of integration of necessary employee and organizational change. Purpose of this paper is, therefore, to propose a theoretical basis for a digitization of SFM through the development of a model including disjunct aspects of SFM as well as a maturity index providing a means to discern different levels of digital solutions. To provide a practical viewpoint in addition to the theoretical basis, concrete SFM methods are collected and mapped to fitting areas as well as maturity levels of the underlying model. Additionally, a two-step questionnaire is conceived to allow for a selective proposition of said methods to derive an implementation sequence. All aspects of the approach are finally validated with an example company.

description: Same but different – XRF study of inks from 13-14th centuries Torah scroll Ms Erfurt 7 (Berlin, Staatsbibliothek Preussicher Kulturbesitz, Ms. Or. fol. 1216) is a thirteenth century Torah scroll from the famous Erfurt collection kept at the Berlin State Library. Multiple corrections, reinking, and three replacement sheets testify to intense ritual use of the scroll. The scroll was investigated in order to compare the ink used in the original and replacement sheets, both for the main text and for corrections. Finally, we answered the scholarly question of whether there was a special practice of writing God’s name. The first survey was performed on-site with a portable XRF spectrometer on a selection of spots, and later it was complemented with XRF scans of several paragraphs of interest with an imaging spectrometer, after permission was granted to bring the scroll to the laboratory. In the presentation, we will show how material analysis of inks can contribute to scholarly research on manuscript and compare what can be achieved on-site with spot analysis, and what questions can be addressed only with use of a scanning device.
