description: The planning and control of intralogistics systems in line with versatile production systems of smart factories requires new approaches and methods to cope with changing requirements within future factories. The planning of intralogistics can no longer follow a static, sequential approach as in the past since the planning assumptions are going to change in a high frequency. Reasons for these constant changes are amongst others external turbulences like rapidly changing market conditions, decreasing batch sizes down to customer-specific products with a batch size of one and on the other hand internal turbulences (like production and logistic resource breakdowns) affecting the production system. This paper gives an insight into research approaches and results how capabilities of intelligent logistical objects (intelligent bins, autonomous transport systems etc.) can be used to achieve a self-organized, cost and performance optimized intralogistics system with autonomously controlled process execution within versatile production environments. A first consistent method has been developed which has been validated and implemented within a scenario at the pilot factory Werk150 at the ESB Business School (Reutlingen University). Based on the incoming production orders, the method of the Extended Profitability Appraisal (EPA) covering the work system value to define the most effective work system for order fulfilment is applied. To derive the appropriate intralogistics processes, an autonomous control method involving principles of decentralized and target-oriented decision-making (e.g. intelligent bins are interacting with autonomously controlled transport systems to fulfil material orders of assembly workstations) has been developed and applied to achieve a target-optimized process execution. The results of the first stage research using predefined material sources and sinks described in this paper is going to set the basis for the further development of a self-organized and autonomously controlled method for intralogistics systems considering dynamic source and sink relations. By allowing dynamic shifts of production orders in the sense of dynamic source and sink relations the cost and performance aims of the intralogistics system can be directly aligned with the aims of the entire versatile production system in the sense of self-organized and autonomously controlled systems.
title: Atomistic simulations of nanoscale molecular and metal oxide junctions

description: The push to continually improve computing power through the further miniaturisation of electronic devices has led to an explosion of "post-Moore" technologies such as molecular electronics and quantum computing. The downscaling of electronic devices has enhanced the importance of quantum effects. As a result to aid in the understanding and development of new devices, accurate and efficient atomistic material modelling methods are crucial for guiding experiments. In this thesis first principle material modelling (e.g Density Functional Theory) is combined with the atomistic Non Equilibrium Green’s Function quantum transport method to study how the electronic structure of two interesting junction systems relate to the electron transport through the junction. These two types of junctions, molecular and metal oxide, have crucial roles to play in the development of molecular based memories and superconducting quantum computing respectively. The first half of this thesis shows how the electronic structure of Polyoxometalate molecules dominate their electron transport properties whilst their redox ability makes them promising for memory applications. The results of the simulations reveal how the charge-balancing counterions of Polyoxometalates increase the conductance of the molecular junctions by stabilisation of unoccupied states, this is a key discovery as the effect of counterions are typically ignored. Polyoxometalates can be altered easily by changing the identity of the central caged atom, enhancing device engineering possibilities. The IV characteristics and capacitance are computed for Polyoxometalates with different caged atoms, the results show how the charge transport and storage can be engineered by choice of caged species and redox state. In the second half of this work, the archetypal Josephson junction, Al/AlOx/Al is explored. The goal was to understand from an atomistic point of view how the nature of the amorphous barrier influences the electron transport. The calculations provide evidence that the oxide concentration of the amorphous barrier significantly influences the resistance of the junction, it is found that oxygen deficient barriers lead to higher than expected critical currents. Unexpectedly the simulations here fail to show an exponential relationship between barrier length and resistance of the device. It is argued that there is an effective barrier length smaller than the physical barrier length due to thinner regions of the barrier. This highlights how important an understanding of the atomic structure of these junctions are for designing high quality junctions for superconducting qubits.

description: Статья посвящена эпитафии (корпус боспорских надписей 718), датирующейся II—III в. В конце эпитафии стоят две буквы, которые считались загадочными всеми издателями надписи. В статье доказывается, что первая буква представляет собой аббревиатуру, означающую «лет (от рождения)», которая засвидетельствована многочисленными надписями из Египта, Кипра, Кирены, острова Тира, а вторая указывает на возраст того, кому был поставлен памятник. Некоторые исследователи считали, что ᾿Αρτίπους является мужским именем. В статье показано, что, хотя в большинстве случаев окончание имени указывает на то, что оно принадлежало мужчине, в ряде случаев имена с подобным окончанием носили женщины. Учитывая, что на рельефе надгробного памятника изображена женщина, есть все основания полагать, что надгробие было поставлено женщине. В статье предлагается следующий перевод надписи: «Артипода, дочь Алкима, 80-ти лет (от роду)».

description: Впервые приведены данные, содержащиеся во французской рукописи середины XV века. До настоящего времени содержание рукописи было неизвестно научной общественности, поскольку рукопись изучалась лишь с точки зрения палеографии, а ее лингвистическое содержание оставалось нераскрытым. Автор статьи провел работу по расшифровке текста рукописи и переводу ее на русский язык. Рукопись выполнена в жанре медицинского трактата и посвящена вопросам охраны и сохранения здоровья. Автор приходит к выводу о том, что практиковавшийся в Средние века медицинский подход представлял собой целостную концепцию охраны здоровья, основными пунктами который были предупреждение и профилактика заболеваний, своевременное очищение и опорожнение организма, тщательный уход и гигиена. В рукописи подчеркивается связь между эмоциональным и физическим состоянием человека, поэтому средневековые авторы рекомендовали предупреждать стрессы и управлять эмоциями с целью сохранения здоровья.

description: It is an axiom of the conflict of laws that one state will not enforce the revenue, penal, or ‘other public’ laws of another. This thesis shall criticise this position, arguing that these exclusionary principles should be replaced with a general principle of enforceability, subject to the control of public policy. It shall begin by sketching the general landscape of the exclusion of foreign law in Anglo-Scots international private law. Thereafter, a detailed account shall be given – for each of the revenue, penal, and ‘other public’ law rules – of the historical development of those exclusions, and their present scope of operation. This exposition provides a foundation for a critical examination of those rules.

description: Previous studies of kinetic transport in the Lorentz gas have been limited to cases where the scatterers are distributed at random (e.g. at the points of a spatial Poisson process) or at the vertices of a Euclidean lattice. In the present paper we investigate quasicrystalline scatterer configurations, which are non-periodic, yet strongly correlated. A famous example is the vertex set of the Penrose tiling. Our main result proves the existence of a limit distribution of the free path length, which answers a question of Wennberg. The limit distribution is characterised by a certain random variable on the space of higher dimensional lattices, and is distinctly different from the exponential distribution observed for random scatterer configurations. The key ingredients in the proofs are equidistribution theorems on homogeneous spaces, which follow from Ratner's measure classification.

description: Faraday Rotation Measure (RM) synthesis requires the recovery of the Faraday Dispersion Function (FDF) from measurements restricted to limited wavelength ranges, which is an ill-conditioned deconvolution problem. Here, we propose a novel deconvolution method based on an extension of the MUltiple SIgnal Classification (MUSIC) algorithm. The complexity and speed of the method is determined by the eigen-decomposition of the covariance matrix of the observed polarizations. We show numerically that for high to moderate Signal to Noise (S/N) cases the RM-MUSIC method is able to recover the Faraday depth values of closely spaced pairs of thin RM components, even in situations where the peak response of the FDF is outside of the RM range between the two input RM components. This result is particularly important because the standard deconvolution approach based on RM-CLEAN fails systematically in such situations, due to its greedy mechanism used to extract the RM components. For low S/N situations, both the RM-MUSIC and RM-CLEAN methods provide similar results.

description: Experimental studies of the diffusion of biomolecules in the environment of biological cells are routinely confronted with multiple sources of stochasticity, whose identification renders the detailed data analysis of single molecule trajectories quite intricate. Here we consider subdiffusive continuous time random walks, that represent a seminal model for the anomalous diffusion of tracer particles in complex environments. This motion is characterized by multiple trapping events with infinite mean sojourn time. In real physical situations, however, instead of the full immobilization predicted by the continuous time random walk model, the motion of the tracer particle shows additional jiggling, for instance, due to thermal agitation of the environment. We here present and analyze in detail an extension of the continuous time random walk model. Superimposing the multiple trapping behavior with additive Gaussian noise of variable strength, we demonstrate that the resulting process exhibits a rich variety of apparent dynamic regimes. In particular, such noisy continuous time random walks may appear ergodic while the naked continuous time random walk exhibits weak ergodicity breaking. Detailed knowledge of this behavior will be useful for the truthful physical analysis of experimentally observed subdiffusion.

description: The concept of a ‘hierarchy of victimhood’ has become a significant phrase in Northern Irish politics, particularly in the aftermath of the Troubles and the subsequent ‘meta-conflict’ following the Good Friday Agreement. Some factions argue for the establishment of a moral hierarchy among victims, while others contend that such a hierarchy already exists, fuelled by sectarian divisions and institutionalized prejudices against the Catholic population. This qualitative study explores the experiences of 35 individuals affected by the Troubles, including 15 members of the security forces, 10 Protestant civilians, and 10 Catholic civilians. A distinct subgroup was also formed, focusing on victims who allege collusion and miscarriages of justice. The primary objective of this study is to investigate whether the support offered to victims through various institutions demonstrates biases based on their religious affiliation in the short to medium term. By conducting interviews and analysing victim testimonies regarding psychological and financial support, the justice process, and media coverage, this study presents victim-centred evidence to examine the existence of hierarchies in the official channels of support provided to these communities. The findings of this study reveal that while there was no deliberate bias based on religious denomination, unintended consequences disproportionately affected Catholic civilian victims. This disparity was particularly evident in the removal of the Historical Enquiry Team and the inadequate financial assistance offered. Moreover, victims of collusion and miscarriages of justice were unjustly denied financial aid and justice due to their classification as non-innocent victims and the alleged misrepresentation of their losses. This study highlights the profound impact of policies that inadvertently perpetuate a hierarchy of victimhood and underscores the importance of fair and equitable support for all victims of the Northern Irish Troubles. It calls for a comprehensive reassessment of existing support systems to ensure equal treatment, regardless of their religious background.

description: We present observations of Neptune's 1- and 3-mm spectrum from the Combined Array for Research in Millimeter-wave Astronomy (CARMA). Radiative transfer analysis of the CO (2-1) and (1-0) rotation lines was performed to constrain the CO vertical abundance profile. We find that the data are well matched by a CO mole fraction of 0.1^+0.2_-0.1 parts per million (ppm) in the troposphere, and 1.1^+0.2_-0.3 ppm in the stratosphere. A flux of 0.5-20 times 10^8 CO molecules cm-2 s-1 to the upper stratosphere is implied. Using the Zahnle et al. (2003) estimate for cometary impact rates at Neptune, we calculate the CO flux that could be formed from (sub)kilometer-sized comets; we find that if the diffusion rate near the tropopause is small (200 cm2 s-1), these impacts could produce a flux as high as 0.5^+0.8_-0.4 times 10^8 CO molecules cm-2 s-1. We also revisit the calculation of Neptune's internal CO contribution using revised calculations for the CO ->CH4 conversion timescale in the deep atmosphere (Visscher et al. 2011). We find that an upwelled CO mole fraction of 0.1 ppm implies a global O/H enrichment of at least 400, and likely more than 650, times the protosolar value.

description: Due to increasing customer requirements and intensifying competition, manufacturing companies are facing growing challenges in the successful order handling. As a result, employees are forced to make increasingly complex decisions in the shortest possible time. At this, the tasks of production planning and control (PPC) are particularly affected. In response to the increasing complexity of tasks, companies rely more than ever on the potential of socio-technical systems, rendered possible by the integration of information systems (IS) in the daily decision-making process. However, due to the increasing complexity of systems used, many users are not capable to raise the potential of information systems acquired, which is why the benefits of IS implementation often fall short of expectations. The following paper thus analyses and structures potential decisive factors causing the lack of problem solving capability in context of using PPC systems. Based on findings from acceptance research, socio-technical influencing factors for the targeted handling of information systems are determined. The developed requirement framework is furthermore compared with current IS implementation strategies to derive future research needs.

description: In recent years, the automobile industry has been calling for new lightweight solutions to fulfill increasing ecologically requirements. A weight reduction of automobile body constructions is necessary to reduce fuel consumption and CO2 emissions. In order to reach this aim, new materials and novel forming processes are required. Also, the importance of aluminum alloys in the automobile industry is constantly increasing. Nowadays, mainly alloys of the 5000 and 6000 aluminum series are used for structure parts or shell parts, respectively. Another alloy series are the 7000 aluminum materials. These alloys offer a great lightweight potential due to their high specific strength combined with a moderate ultimate elongation. Nevertheless, these alloys are not yet widely used in the automobile industry. The reason is the limited formability of 7000 aluminum at room temperature in high-strength heat treatment condition. There are two approaches to increase the formability based on elevated temperatures, specifically the two processes of warm and hot forming at temperatures lower than the recrystallization temperature or above it, respectively. This paper deals with the investigation of the influence of forming conditions, especially the forming temperature. Trapezoidal parts were deep-drawn at different forming temperatures and subsequently investigated by determining the deformation with an optical measurement system as well as the springback of the material. In addition, the influence of the forming temperature on the flange feed was investigated as well as the influence of the paint bake process on the artificial aging step. Results show, that the formability increases with increasing forming temperature in the warm forming process route. Also, the artificial aging time can be decreased by a combined aging with paint bake heat treatment.

description: Large and complex products such as aircrafts or wind energy plants are usually produced in small batches. This leads to particular requirements for logistics with regard to process efficiency, flexibility and reliability as well as coordination and control of the processes. In practice, the consolidation of parts from different storage areas is a labour-intensive process, which must be considered in the planning or remodelling of warehouses. This work presents an analytical model to determine the consolidation time within a single formula at an early planning stage. Within this formula transport, handling, base and allowance times are considered. Finally, the analytical model is applied in an industrial project which deals with the new planning of warehouses for a large equipment manufacturer. The presented work connects academic approaches for calculating the commissioning time with practical experiences gained in industrial projects. Researchers benefit from this work, as practical considerations and corresponding solutions are pointed out and insights into practical projects are given, while logistics planners could benefit by applying the developed model.

description: The threat of ultra wideband (UWB) sources is interesting for military issues. This paper summarizes information concerning the voltages generated from some commercially available UWB generator systems and their produced electromagnetic fields. The paper focuses on the coupling of UWB fields into electronic equipment and discusses possible modeling and measurement techniques to estimate such a threat for modern ships. An evaluation procedure for the determination of the induced voltage at the input of an electronic component is presented. This method is based on the computation of the internal electric field and the measurements on a test network, which is similar to the structure of the steering control cabling. It allows the estimation of the potential threat for the ship's electronic equipment due to the exposal to UWB emitting sources.

description: Rising consumption due to a growing world population and increasing prosperity, combined with a linear economic system have led to a sharp increase in garbage collection, general pollution of the environment and the threat of resource scarcity. At the same time, the perception of environmental protection becomes more sensitive as the consequences of neglecting sustainable business and eco-efficiency become more visible. The Circular Economy (CE) could reduce waste production and is able to decouple economic growth from resource consumption, but most of the products currently in use are not designed for the reuse-forms of the CE. In addition, the decision-making process of the End-of-Usage (EoU) products regarding the following steps has further weaknesses in terms of economic attractiveness for the participants, which leads to low return rates and thus the disposal is often the only alternative. This paper proposes a model of the decision-making process, which uses machine learning. For this purpose, a Machine Learning (ML) classification is created, by applying the waterfall model. An artificial neural network (ANN) uses information about the model, use phase and the obvious symptoms of the product to predict the condition of individual components. The resulting information can be used in a downstream economic and ecological evaluation to assess the possible next steps. To test this process comprehensive training data is simulated to train the ANN. The decentralized implementation, cost savings and the possibility of an incentive system for the return of an end-of-usage product could lead to increased return rates. Since electronic devices in particular are attractive for the CE, laptops are the reference object of this work. However, the obtained findings are easily applicable to other electronic devices.

description: The complexity of manual assembly is continuously increasing due to a large variety of products, multi-product assembly or a batch size of one. To stay ahead in competency and competition, and to ensure adaptability and flexibility in today’s dynamic production environment, awareness of knowledge as the 4th factor of production, as well as the effective management of knowledge, are crucial. The present research therefore aimed at further advancing knowledge management in manual assembly by (1) assessing cognitive assistance systems and organisational incentive systems by use of an online survey distributed to German production companies, and by (2) applying the Analytical Hierarchy Process (AHP) as a transparent decision-making tool for knowledge-based improvements in the manual assembly process and workplace design. By employing an exemplary case of two feasible assembly alternatives, the AHP was applied as a method of knowledge measurement in a specific use case revealing priorities for knowledge-based ideas. To properly compute a final priority ranking of workers’ knowledge ideas, an algorithm written in Python programming language in accordance with the problem-solving framework previously published by Thomas L. Saaty (Decision Sciences, 18: 157-177, 1987). The performance of the algorithm shows that the rating process can be standardised and automated to a high level, and that the AHP may thus provide supportive evidence for assembly optimisation. The AHP-derived results can be used as a suitable basis for a bonus-point incentive system, which should contain both material and immaterial incentives. To operationalise this, it is therefore recommended to integrate the AHP rating process into a knowledge management application of hand-held devices, such as tablets, which are widely used in the production environment.

description: The 1950s and 1960s are often regarded as a transitory time period for the American homosexual man, overshadowed by the end of World War II and the tumultuous and radically influential Gay liberation movement beginning in the 1970s. The time period is marked by the publication and increased scrutiny of several influential novels: Christopher Isherwood's A Single Man (1964), Chester Himes's Yesterday Will Make You Cry (1937), James Baldwin's Giovanni’s Room (1956), and Gore Vidal's The City and the Pillar (1948). These novels highlight the tensions of competing forces of continuing repression and increasing acceptance, and complicate and explore the richness and heterogeneity of the gay identity, even before it has fully nucleated in pre-Stonewall America. The novels’ protagonists often have strained relationships both with the conventional society in which they live, but also the homosexual communities that exist around them. The protagonists recast their homosexual relationships as ephemeral, exceptional in nature, or with conventional labels, revealing complex and contradictory ideas about their own sexual identities. The protagonists are forced to come to terms with their identities, a process more complicated than simply coming out to the world and crossing the not-so-singular threshold often associated with the contemporary 'gay closet.' Finally, the novels' often tragically unresolved endings challenge the idea that they may serve as "support" novels for their gay communities; instead, they are better understood as novels of "identification", since they uncompromisingly cover issues that have gone uncovered before this period, identifying the problems that the isolated homosexual may feel, and highlighting and scrutinizing a lack of conventional resolution.

description: Pitch bearings of wind turbines are large, grease-lubricated rolling bearings that connect the rotor blades with the rotor hub. They are used to turn the rotor blades to control the power output and/or structural loads of the turbine. Common actuators turning the blades are hydraulic cylinders or electrical motor / gearbox combinations. In order to design pitch actuator systems that are able to turn the blades reliably without imposing an excessive power demand, it is necessary to predict the friction torque of pitch bearings for different operating conditions. In this paper, the results of torque measurements under load are presented and compared to results obtained using different calculation models. The results of this comparison indicate the various sources of friction that should be taken into account for a reliable calculation model.

description: The supply of customer-specific products is leading to the increasing technical complexity of machines and plants in the manufacturing process. In order to ensure the availability of the machines and plants, maintenance is considered as an essential key. The application of cyber-physical systems enables the complexity to be mastered by improving the availability of information, implementing predictive maintenance strategies and the provision of all relevant information in real-time. The present research project deals with the development of a cost-effective and retrofittable smart maintenance system for the application of ultraviolet (UV) lamps. UV lamps are used in a variety of applications such as curing of materials and water disinfection, where UV lamps are still used instead of UV LED due to their higher effectiveness. The smart maintenance system enables continuous condition monitoring of the UV lamp through the integration of sensors. The data obtained are compared with data from existing lifetime models of UV lamps to provide information about the remaining useful lifetime of the UV lamp. This ensures needs-based maintenance measures and more efficient use of UV lamps. Furthermore, it is important to have accurate information on the remaining useful lifetime of a UV lamp, as the unplanned breakdown of a UV lamp can have far-reaching consequences. The key element is the functional model of the envisioned cyber-physical system, describing the dependencies between the sensors and actuator, the condition monitoring system as well as the IoT platform. Based on the requirements developed and the functional model, the necessary hardware and software are selected. Finally, the system is developed and retrofitted to a simulated curing process of a 3D printer to validate its functional capability. The developed system leads to improved information availability of the condition of UV lamps, predictive maintenance measures and context-related provision of information.

description: Современная конкуренция городов за туристов, инвесторов, потенциальных жителей сегодня происходит в символическом пространстве. Города стремятся завоевать доверие целевых аудиторий, повысить свою значимость, узнаваемость, обеспечить устойчивость идентификации, то есть накопить символические ресурсы. В качестве символического ресурса может рассматриваться и культурная память города, которая представляет собой социокультурный конструкт. Ресурсный потенциал культурной памяти города (от брендирования мест до формирования позитивной городской идентичности) автором статьи раскрывается исходя из символической природы и ключевых свойств коллективной памяти. Одним из важных условий функционирования символического ресурса культурной памяти города является коммеморация как процесс актуализации культурных смыслов, поддержки и воспроизводства аутентичных фрагментов памяти в коммуникативных практиках города.

description: In den letzten Jahrzehnten hat die technologische Entwicklung in der Gesellschaft enorme Fortschritte gemacht. Neben den zahlreichen Vorteilen, die diese Technologisierung bietet, steigt jedoch ebenfalls die Abhängigkeit von elektronischen Systemen. Eine Störung von IT-Systemen durch elektromagnetische Quellen kann daher schwere Folgen haben. Um das Risiko einer störenden Beeinflussung zu verringern ist es wichtig, die Empfindlichkeit elektronischer Systeme auf typische Störsignalformen zu testen. Neben den üblichen in der Normung benutzten Signalformen wie CW und dem gedämpften Sinus, werden breitbandige transiente Störimpulse immer interessanter. Handelsübliche Impulsgeneratoren liegen jedoch preislich im Bereich von mehreren Zehntausend Euros. Außerdem sei zu beachten dass solche Systeme zumeist nicht für den privaten Gebrauch gekauft werden können. Diese Arbeit beschäftigt sich daher damit, eine möglichst einfach zu realisierende und kostengünstige Breitband-Testquelle zu konstruieren. Diese soll helfen, eine schnelle Abschätzung durchführen zu können, wie gut die Störfestigkeit elektronischer Systeme gegenüber transienter Störeinkopplung ist. Der prinzipielle Aufbau einer elektromagnetischen Quelle lässt sich in verschiedene Blöcke unterteilen und ist in Abbildung 1 dargestellt. Zunächst wird eine Energiequelle benötigt, welche die nachfolgenden Stufen versorgt. Der nächste Schritt dient der Umwandlung der Energiequellenspannung in eine Hochspannung. Diese wird anschließend im Impulsformer zunächst gesammelt und danach mit sehr hoher Spitzenleistung abgegeben. Die verwendete Impulsform, hängt von der, je nach Zielumgebung geforderten Bandbreite ab. Dem Impulsformer folgt oftmals ein Modulator. Dieser hat die Aufgabe den Sendeimpuls derart zu modulieren, dass sie einem bestimmten Sendeprotokoll entspricht. Dies kann genutzt werden um gezielt die Störanfälligkeit von Übertragungen zweier kommunizierender Systeme zu testen. Als letzte Stufe folgt die Abstrahlung des Testimpulses mittels einer oder mehrerer angepasster Antennen. Hierbei ist es von hoher Bedeutung, dass die Antenne die geforderte Bandbreite, Richteigenschaft und Anpassung besitzt, damit ein hoher Anteil der erzeugten Energie ins Feld abgestrahlt wird.
