Summary of the 8th Workshop on Metallization and Interconnection for Crystalline Silicon Solar Cells
(2019)
This article gives a summary of the 8th Metallization and Interconnection workshop and attempts to place each contribution in the appropriate context. The field of metallization and interconnection continues to progress at a very fast pace. Several printing techniques can now achieve linewidths below 20 μm. Screen printing is more than ever the dominating metallization technology in the industry, with finger widths of 45 μm in routine mass production and values below 20 μm in the lab. Plating technology is also being improved, particularly through the development of lower cost patterning techniques. Interconnection technology is changing fast, with introduction in mass production of multiwire and shingled cells technologies. New models and characterization techniques are being introduced to study and understand in detail these new interconnection technologies.
Viele touristische Aktivitäten sind mit einem erhöhten Energiebedarf (Strom, Wärme, Kraftstoffe) verbunden, sodass Tourismus nicht losgelöst von der Energiewirtschaft bzw. deren Klimawirksamkeit zu betrachten ist. Das Projekt befasst sich daher mit der Triade Tourismus, Klimawandel und erneuerbare Energienutzung.
Die Veränderungen des Klimas stellen den Tourismus vor neue Herausforderungen. Um diesen Herausforderungen, im Sinne eines nachhaltigen Tourismus gerecht zu werden, kann der Tourismus dem Klimawandel mit Anpassungs- und/oder Vermeidungsstrategien begegnen (vgl. ELSASSER ET AL. 2000). Im Rahmen dieses Projektes werden sowohl mögliche Anpassungs- als auch Vermeidungsstrategien thematisiert. Ein besonderer Fokus wird dabei zum einen auf die Nutzung von erneuerbaren Energien (EE) gelegt. Zum anderen werden die Entwicklungen des Tourismus und die Anpassungen an die Änderungen des Klimas vornehmlich in Bezug auf den Wintertourismus betrachtet. Räumlich konzentriert sich das Projekt auf das Mittelgebirge Schwarzwald.
This paper presents a new likelihood-based partitioning method of the measurement set for the extended object probability hypothesis density (PHD) filter framework. Recent work has mostly relied on heuristic partitioning methods that cluster the measurement data based on a distance measure between the single measurements. This can lead to poor filter performance if the tracked extended objects are closely spaced. The proposed method called Stochastic Partitioning (StP) is based on sampling methods and was inspired by a former work of Granström et. al. In this work, the StP method is applied to a Gaussian inverse Wishart (GIW) PHD filter and compared to a second filter implementation that uses the heuristic Distance Partitioning (DP) method. The performance is evaluated in Monte Carlo simulations in a scenario where two objects approach each other. It is shown that the sampling based StP method leads to an improved filter performance compared to DP.
These days, medical applications of shape memory alloys (SMAs) can be found in cardiovascular devices, gastroenterology and urology as well as in the area of orthopedic implants, orthodontic devices and clinical instrumentation. Their functional properties combined with excellent biocompatibility increase the possibility and the performance of minimally invasive surgeries. Overviews of existing applications can be found in [1-2]. Within the medical field, most of the applications with shape memory (SM) material take advantage of the superelasticity of NiTi SMAs. In contradiction to the superelastic or mechanical SM effect, the application described in this study uses the thermal SM effect for a new medical implant. Before explaining the SM driven intramedullary bone nail in detail, a short introduction to the bone elongation technique is given.
The background of this application on based in the medical fact that normally any tissue reacts to an injury with repair and healing processes through multiplication of cells. If after a transverse osteotomy a strain stimulus is activated, for example by tensile stress, this multiplication of cells and new formation of tissue may be continued for any length of time. Due to this mechanism, even considerable loss of bone caused by fractures or congenital defective positions, may be compensated without bone grafts. The technique of callus distraction by means of external fixation or intramedullary nail stimulates the formation of callus in the bone gap. Callus is the repair tissue of the bone generated in the fracture gap in case of bone fracture or osteotomy. The gap to be bridged should not be wider than 1 mm per day [3]. The process starts with the exudation of callus around the ends of the broken bone. At first, callus is more like a fibrous tissue. Later it hardens due to deposition of calcium and eventually it is converted into true bone. Three weeks after severance, the vascular system is formed. An overview of current bone lengthening techniques, also called callus distraction, can be found in [3]. External systems are normally used for the extension of bones, the bone fragments being fixed on rings by wires. The decisive disadvantages of those external systems are primarily the considerable risk of infection due to protruding wires, noticeable discomfort for the patient because of the external rings, a coarse cosmetic result because of scarring, as well as rather long hospitalization.
Therefore, internal bone extension systems are of great interest to orthopedic surgery.
Die Entstehung von Radsatz-Torsionsschwingungen kann aufgrund der zunehmenden Ausnut- zung des Kraftschlusses im Rad-Schiene-Kontakt nicht vollends verhindert werden. Während analytische Untersuchungen zeigen, dass bei der Überschreitung eines bestimmten Dämp- fungswerts die Entstehung von Radsatz-Torsionsschwingungen vollständig vermieden wird, zeigen Simulationen, dass die Schwingungsamplitude des dynamischen Torsionsmoments in- folge des betragsmäβig sinkenden Kraftschlussgradienten und einer gewissen Antriebsstrang- dämpfung bei höheren Gleitgeschwindigkeiten begrenzt ist. Im Gegensatz zur analytischen Formel (17) ist damit ein maximales, dynamisches Torsionsmoment berechenbar.
Durch eine ganzheitliche Betrachtung des Gesamtsystems, bestehend aus dem Kraftschluss zwischen Rad und Schiene, dem Radsatz inkl. Lagerung, sowie Antriebsstrang können ver- schiedene Einflussfaktoren untersucht werden, die eine Radsatz-Torsionsschwingung beein- flussen. Die damit verbundenen Berechnungsmodelle sind aufgrund der Anzahl von Massen und Freiheitsgraden nicht mehr analytisch lösbar. Durch den Einsatz von Mehrkörperdynamik-Software können die Einflussfaktoren identifiziert und deren Einfluss auf die Torsionsneigung des Systems und das dynamische Torsionsmoment quantifiziert werden.
Die Datenschutz-Grundverordnung (DSGVO) sieht in Art. 82 DSGVO einen Anspruch auf Ersatz materieller und immaterieller Schäden vor, allerdings ohne Aussagen darüber, wie die Schadenshöhe zu bestimmen ist. Der Beitrag beleuchtet die bisherige Gerichtspraxis kritisch und zeigt auf, welche Kriterien speziell in data leakage-Fällen herangezogen werden können, um die Schadenshöhe zu bestimmen. Aus der Sicht von Betroffenen stellt sich die Frage nach effektiver Rechtsdurchsetzung, aus der Sicht von Unternehmen stellt sich die Frage nach Prävention und Abwehr von Ansprüchen.
When a country grants preferential tariffs to another, either reciprocally in a free trade agreement (FTA) or unilaterally, rules of origin (RoOs) are defined to determine whether a product is eligible for preferential treatment. RoOs exist to avoid that exports from third countries enter through the member with the lowest tariff (trade deflection). However, RoOs distort exporters' sourcing decisions and burden them with red tape. Using a global data set, we show that, for 86% of all bilateral product-level comparisons within FTAs, trade deflection is not profitable because external tariffs are rather similar and transportation costs are non-negligible; in the case of unilateral trade preferences extended by rich countries to poor ones that ratio is a striking 98%. The pervasive and unconditional use of RoOs is, therefore, hard to rationalize.
Purpose – The purpose of this paper is to examine visitor management in the German-Swiss border area of the Lake Constance region. Taking a customer perspective, it determines the requirements for an application with the ability to optimize personal mobility.
Design/methodology/approach – A quantitative study and a survey of focus groups were conducted to identify movement patterns of different types of visitors and their requirements concerning the development of a visitor management application.
Findings – Visitors want an application that provides real-time forecasts of issues such as traffic, parking and queues and, at the same time, enables them to create a personal activity schedule based on this information.
Research limitations/implications – Not every subsample reached a sufficient number of cases to yield representative results.
Practical implications – The results may lead to an optimization and management separation of mobility flows in the research area and be helpful to municipal planners, destination marketing organizations and visitors.
Originality/value – The German border cities of Konstanz, Radolfzell and Singen in the Lake Constance region need improved visitor management, mainly because of a high level of shopping tourism by Swiss visitors to Germany. In the Summer months, Lake Constance is also a popular destination for leisure tourists, which causes overtourism. For the first time, the results of this research presented here offer possible solutions, in particular by showing how a mobile application for visitors could defuse the situation.
Zusammenfassende Darstellung der Ergebnisse einer empirischen Studie über Friedens- und Postkonfliktarbeit durch kirchliche Akteure in Indonesien ( Maluku) und auf den Philippinen (Mindanao). Auf Basis der Untersuchung ziehen die Autoren Schlussfolgerungen über die praktische Bedeutung kirchlicher Friedensprojekte nach Konflikten
Drawing on a rich body of multimethod field research, this book examines the ways in which Indonesian and Philippine religious actors have fostered conflict resolution and under what conditions these efforts have been met with success or limited success.
The book addresses two central questions: In what ways, and to what extent, have post-conflict peacebuilding activities of Christian churches contributed to conflict transformation in Mindanao (Philippines) and Maluku (Indonesia)? And to what extent have these church-based efforts been affected by specific economic, political, or social contexts? Based on extensive fieldwork, the study operates with a nested, multi-dimensional, and multi-layered methodological concept which combines qualitative and quantitative methods. Major findings are that church-based peace activities do matter, that they have higher approval rates than state projects, and that they have fostered interreligious understanding.
Through innovative analysis, this book fills a lacuna in the study of ethno-religious conflicts. Informed by the novel Comparative Area Studies (CAS) approach, this book is strictly comparative, includes in-case and cross-case comparisons, and bridges disciplinary research with Area Studies. It will be of interest to academics in the fields of conflict and peacebuilding studies, interreligious dialogue, Southeast Asian Studies, and Asian Politics.
This document presents an algorithm for a non-obtrusive recognition of Sleep/Wake states using signals derived from ECG, respiration, and body movement captured while lying in a bed. As a core mathematical base of system data analytics, multinomial logistic regression techniques were chosen. Derived parameters of the three signals are used as the input for the proposed method. The overall achieved accuracy rate is 84% for Wake/Sleep stages, with Cohen’s kappa value 0.46. The presented algorithm should support experts in analyzing sleep quality in more detail. The results confirm the potential of this method and disclose several ways for its improvement.
