    No full text
    This thesis is a study of the Gothic fiction of Sabine Baring-Gould (1834- 1924), with particular attention given to Baring-Gould’s roles as squire and parson. I have chosen to analyze two of Baring-Gould’s Gothic works, the novel Mehalah (1880) and the novella Margery of Quether (1884), both which allow a particularly profitable examination of the influence of Baring-Gould’s roles on his fiction. In studying these texts I apply my theory of Gothic fiction as a particularly modern genre built upon a "Gothic threshold," a meeting point of extreme opposites which ambivalently contrasts and merges the categories of the modern and the medieval. In the first chapter I describe how Baring-Gould’s unique Hegelian-influenced Tractarian philosophy influenced his creation of the dialectical setting of Mehalah. I argue that because of this influence Mehalah should be recognized as a significant contribution to the literature of the Oxford Movement. In the second chapter I argue that Mehalah’s historical setting in the time of the French Revolution and the influence of Wuthering Heights reinforce Mehalah’s use of the “Gothic threshold” structure and contribute to its theme of ambivalent progress. In the third chapter I discuss the influence of Baring-Gould’s sermon-writing on Mehalah and consider connections between Baring-Gould’s role as parson and the novel’s botched marriage theme. In the final chapter I discuss Margery of Quether as an innovation in the Gothic and vampire tradition as perhaps the only Gothic work that directly dramatizes the Land Law debate and presents that debate as a "Gothic" contest. I argue that Margery channels Baring-Gould’s tensions as a landowner. In the conclusion I argue that Mehalah and Margery display Baring-Gould’s technique of constructing miniature Gothic battles that relate to larger confrontations, and that the ultimate terror presented in these works is the conclusion of the battle between ancient and modern forces

    Design reuse, i.e. reuse of design artefacts of space missions is gaining more importance in the frame of cost efficiency improvement i.e. getting more science out of the limited funding in space systems development. This has found application in the Earth orbiting spacecraft sector, but may also be of interest for deep space scientific missons. This thesis contributes to the practice of design reuse with the development and demonstation of a method for a more systematic reuse approach as compared to the ad-hoc reuse widely common. Using a real life reuse case from an ESA phase A mission concept study, the process is described based on a developed general ontology of system design under consideration of the pecularities of a deep space scientific misson and uses Model-Based Systems Engineering methods. A Reuse Matrix has been proposed as a tool to analyse reuse effort a-priori based on individual delta development effort of components and the propagation of changes over the component borders. The latter are shown to be depending on aspects such as the number of interfaces and the number of constraints involved in the change propagation, as well as the extent of change of the latter. Three different case studies are presented: (1) a single reuse scenario, which develops a mission concept for a MASCOT-derived Phobos surface station using the presented method and derives the reuse matrix for this special case; (2) a platform based design-for-reuse analysis, which determines requirements and derives a platform approach for nanolander systems based on the MASCOT lander heritage and (3) a modular lunar infrastructure designed for a special case of reuse of the same system design for different use cases in one mission scenario. The three case studies prove the general applicability of the process and the usability of the Reuse Matrix, which benefits from the existence of a desciptive system model including system requirements, functional breakdown and physical allocation, as well as connected performance models which are fed with the information stored in the system model. The MASCOT lander system design has been demonstrated as very well suited for effective reuse and shows to be a good starting point for a platform-based family of nanolander for a broad variety of small and airless bodies

    This study looks at the numerous studies of Islamic theology conducted by Western nations since the early nineteenth century. They studied Muslim thinkers' writings and brought them to the West. Initially, the study of the manuscript was general in nature, but later thinkers narrowed it down to a specific study. Sabine Schmidtke is a modern Orientalist who specializes in manuscripts of Islamic theology, particularly Mu'tazilah theology. In this study, the author employs the library research method to examine Sabine Schmidtke's books and journals on the relationship between Jewish Karaites, Shia theology and Mu'tazilah theology. Based on the author's research, Sabine's comparative historical and textual studies have revealed that the Shia school of thought and the Jewish Karaites sect have adopted Mu'tazilah thought, specifically the thought of Abu al-Husayn al-Basri. They not only adopted ideas, but they also copied and preserved writings found in Yemen in the form of manuscripts. Keywords: Sabine Schmidtke, Jewish Karaites, Mu'tazilah

    Published in print by Universitätsverlag der TU Berlin, ISBN 978-3-7983-2968-3 (ISSN 2512-5141)This thesis investigates a new concept for the flexible design and verification of an ADCS for a nanosatellite platform. In order to investigate guidelines for the design of a flexible ADCS, observations of the satellite market and missions are recorded. Following these observations, the author formulates design criteria which serve as a reference for the conceptual design of the flexible ADCS. The research of the thesis was carried out during the development of TU Berlin's nanosatellite platform TUBiX20 and its first two missions, TechnoSat and TUBIN. TUBiX20 targets modularity, reuse and dependability as main design goals. Based on the analysis of design criteria for a flexible ADCS, these key design considerations for the TUBiX20 platform were continued for the investigations carried out in this thesis. The resulting concept implements the ADCS as a distributed system of devices complemented by a hardware-independent core application for state determination and control. Drawing on the technique of component-based software engineering, the system is partitioned into self-contained modules which implement unified interfaces. These interfaces specify the state quantity of an input or output but also its unit and coordinate system, complemented by a mathematical symbol for unambiguous documentation. The design and verification process for the TUBiX20 ADCS was also elaborated during the course of this research. The approach targets the gradual development of the subsystem from a purely virtual satellite within a closed-loop simulation to the verification of the fully integrated system on an air-bearing testbed. Finally, the concurrent realization of the investigated concept within the TechnoSat and TUBIN missions is discussed. Starting with the individual ADCS requirements, the scalability of the approach is demonstrated in three stages: from a coarse, but cost- and energy-efficient configuration to realize a technology demonstration mission with moderate requirements (TechnoSat) to a high-performance configuration to support Earth observation missions (TUBIN).Diese Dissertation untersucht ein neues Konzept zur flexiblen Entwicklung und Verifikation eines Lageregelungssystems für eine Nanosatellitenplattform. Als Grundlage für die Erarbeitung eines Leitfadens für die Entwicklung werden zunächst Beobachtung des Satellitenmarkts sowie konkreter Missionen zusammengetragen. Darauf aufbauend formuliert der Autor Entwurfskriterien für die Konzipierung eines flexiblen Lageregelungssystems. Die Dissertation wurde im Rahmen der Entwicklung der TUBiX20 Nanosatellitenplattform und ihrer ersten beiden Missionen, TechnoSat und TUBIN, an der TU Berlin durchgeführt. TUBiX20 verfolgt Modularität, Wiederverwendung und Zuverlässigkeit als Entwicklungsziele. Diese werden unter der Verwendung der vom Autor hergeleiteten Entwurfskriterien in dieser Arbeit im Kontext des Lageregelungssystems verfeinert. Das resultierende Konzept setzt dieses als verteiltes System von Geräten und einem hardware-unabhängigen Software-Kern um. Der Software-Entwurfstechnik Component-based software engineering folgend ist das System in unabhängige Module unterteilt, welche wiederum einheitliche Schnittstellen implementieren. Diese Schnittstellen spezifizieren die Zustandsgrößen für die Ein- und Ausgänge der Module inklusive Einheit, Koordinatensystem und mathematischem Symbol für eine eindeutige Darstellung. Der Entwurfs- und Verifikationsprozess für das TUBiX20 Lageregelungssystem wurde vom Autor im Rahmen der Arbeit untersucht. Hier verfolgt der Ansatz einen schrittweisen übergang von einem virtuellen Satelliten als Simulationsmodell bis hin zur Verifikation des integrierten Systems auf einem Lageregelungsteststand. Abschließend diskutiert die Arbeit die Realisierung des untersuchten Konzepts im Rahmen der Missionen TechnoSat und TUBIN. Beginnend mit den jeweiligen Anforderungen wird die Skalierbarkeit des Ansatzes in drei Stufen demonstriert: von einer groben, aber kosten- und energieeffizienten Konfiguration für eine Technologieerprobungsmission mit moderaten Anforderungen (TechnoSat) bis hin zu einer Konfiguration für hochgenaue Lageregelung als Basis für Erdbeobachtungsmissionen (TUBIN)

    In the recent years satellite launches have increased signifi cantly. This trend is further pushed by big constellations and the new space movement. With the increasing amount of satellites, the data processing capabilities on ground need to grow accordingly. This thesis conquers the task of designing eff ective satellite payload ground processing networks using state of the art technologies. The focus is on separating the payload data processing algorithms from the underlying software architecture algorithms. With the resulting framework, a fl exible and scalable architecture is designed to host processing algorithms. The target user for the introduced handling system is seen in small institutions, universities and Small and Medium-sized Enterprises (SMEs). The thesis aims to build a knowledge base compared to the proprietary, closed source solutions on the market. This thesis describes payload data from satellite missions, data processing level used and sets the focus on image data, as they are a big driver for ground processing. The steps, necessary to process satellite payload data is illustrated. For the underlying software architecture to process satellite data, commercial processing pipelines are introduced. Next to software basics like data exchange formats, databases and software deployment, software architectures are described. As the Flying Laptop mission is used as an example for the payload datahandling, it is introduced with its optical and ship data receiving payloads. The Payload On-board Computer (PLOC) is characterized next to the ground segment, the payload handling is embedded into. The processing of data is defi ned with six requirements using the Flying Laptop mission as an example. They range from data assembly and data correction to calibration, demosaicing, georeferencing and AIS data decoding. These requirements are proven to be checked by the implemented payload handling. Raw payload products with its anomalies are illustrated in this thesis, while presenting implemented and possible solutions for these anomalies. This includes image readout anomalies as well as brightness anomalies, fi ltered out during calibration. For the AIS ship data of Flying Laptop, a performance analysis of the instrument is presented. Next to the payload data processing, the implemented software framework is described. Requirements, defi ning such a handling system implementation are listed. They include backup capabilities, automatic processing, accessibility with new processing steps and user access. In addition, decentralization, extensibility and usability for other missions is required. The concept of nodes is the central element of the payload data handling framework. A node represents an atomic unit, capable of receiving data, altering, and forwarding them. Diff erent node types to assemble, process and store the data are identifi ed. Used database concepts are described and how the data on diff erent level is stored within. To enable users to gain access to the data, a front end and an API solution is implemented. Both provide diff erent query options to fetch data according to needs. A possible deployment philosophy using system services on Ubuntu machines is introduced. With the payload handling pipeline implemented for the Flying Laptop mission, results are presented. Several thousand images and more than 1.35 million AIS messages are received and processed. The introduced payload handling concepts can streamline the payload processing and enable companies and institutions to focus on their core business and value chain
