Ideology and Holy Landscape in the Baltic Crusades

This book examines how the military orders and the ideology of crusading gave rise to a new sacred landscape in the medieval Baltic region, an outpost of Latin Christianity. Drawing on a wide variety of sources and international scholarship, the book discusses the paganism of the landscape in written sources pre-dating the crusades, in addition to the narrative, legal, and visual evidence of the crusade period. It draws out the key sacralizing elements as expressed in those sources, which structure the definition of sacred landscape, particularly martyrdom, the manifestation of the sacred, and use of relics in battle. By analyzing these aspects with Geographical Information Systems (GIS), a map of the Baltic campaigns emerges that provides a fresh approach to studying contemporary views of holy war in a region with no initial links to the loca sancta of Jerusalem or Europe

A practical key management and distribution system for IPTV conditional access

Conditional Access (CA) is widely used by pay-television operators to restrict access to content to authorised subscribers. Commercial CA solutions are available for structured broadcast and Internet Protocol Television (IPTV) environments, as well as Internet-based video-on-demand services, however these solutions are mostly proprietary, often inefficient for use on IP networks, and frequently depend on smartcards for maintaining security. An efficient, exible, and open conditional access system that can be implemented practically by operators with large numbers of subscribers would be beneficial to those operators and Set-Top-Box manufacturers in terms of cost savings for royalties and production costs. Furthermore, organisations such as the South African Broadcasting Corporation that are transitioning to Digital-Terrestrial-Television could use an open Conditional Access System (CAS) to restrict content to viewing within national borders and to ensure that only valid TV licence holders are able to access content. To this end, a system was developed that draws from the area of group key management. Users are grouped according to their subscription selections and these groups are authorised for each selection's constituent services. Group keys are updated with a key-tree based approach that includes a novel method for growing full trees that outperforms the standard method. The relations that are created between key trees are used to establish a hierarchy of keys which allows exible selection of services whilst maintaining their cryptographic protection. Conditions for security without dependence on smartcards are defined, and the system is expandable to multi-home viewing scenarios. A prototype implementation was used to assess the proposed system. Total memory consumption of the key-server, bandwidth usage for transmission of key updates, and client processing and storage of keys were all demonstrated to be highly scalable with number of subscribers and number of services

Terra matris: crusading, the military orders, and sacred landscapes in the Baltic, 13th – 14th Centuries

Crusading and the military orders have, at their roots, a strong focus on place, namely the Holy Land and the shrines associated with the life of Christ on Earth. Both concepts spread to other frontiers in Europe (notably Spain and the Baltic) in a very quick fashion. Therefore, this thesis investigates the ways that this focus on place and landscape changed over time, when crusading and the military orders emerged in the Baltic region, a land with no Christian holy places. Taking this fact as a point of departure, the following thesis focuses on the crusades to the Baltic Sea Region during the thirteenth and fourteenth centuries. It considers the role of the military orders in the region (primarily the Order of the Teutonic Knights), and how their participation in the conversion-led crusading missions there helped to shape a distinct perception of the Baltic region as a new sacred (i.e. Christian) landscape. Structured around four chapters, the thesis discusses the emergence of a new sacred landscape thematically. Following an overview of the military orders and the role of sacred landscpaes in their ideology, and an overview of the historiographical debates on the Baltic crusades, it addresses the paganism of the landscape in the written sources predating the crusades, in addition to the narrative, legal, and visual evidence of the crusade period (Chapter 1). It then proceeds to a chapter-by-chapter analysis considering specific sacralising elements expressed in the sources, which structure the definition of sacred landscape used in this thesis (outlined in the Introduction). Chapter 2 considers the role martyrdom in sacralising the landscape, followed by a discussion of the role played by relics (Chapter 3), ritualization, and sacred space (Chapter 4). By incorporating Geographical Information Systems (GIS) into the analysis of the texts, a new spatial map of the Baltic campaigns emerges from the present study, providing a fresh approach to studying contemporary views of holy war in a region with no holy (i.e. Christian) shrines

An In-Memory XQuery/XPath Engine over a Compressed Structured Text Representation

We describe the architecture and main algorithmic design decisions for an XQuery/XPath processing engine over XML collections which will be represented using a self-indexing approach, that is, a compressed representation that will allow for basic searching and navigational operations in compressed form. The goal is a structure that occupies little space and thus permits manipulating large collections in main memory

Numerical and experimental investigations for insulation particle transport phenomena in water flow

The investigation of insulation debris generation, transport and sedimentation becomes more important with regard to reactor safety research for pressurized and boiling water reactors, when considering the long-term behaviour of emergency core coolant systems during all types of loss of coolant accidents (LOCA). The insulation debris released near the break during a LOCA incident consists of a mixture of a disparate particle population that varies with size, shape, consistency and other properties. Some fractions of the released insulation debris can be transported into the reactor sump, where it may perturb or impinge on the emergency core cooling systems. Open questions of generic interest are for example the particle load on strainers and corresponding pressure-drop, the sedimentation of the insulation debris in a water pool, its possible re-suspension and transport in the sump water flow. A joint research project on such questions is being performed in cooperation with the University of Applied Science Zittau/Görlitz and the Forschungszentrum Dresden-Rossendorf. The project deals with the experimental investigation and the development of computational fluid dynamic (CFD) models for the description of particle transport phenomena in coolant flow. While the experiments are performed at the University Zittau/Görlitz, the theoretical work is concentrated at Forschungszentrum Dresden-Rossendorf. In the present paper, the basic concepts for computational fluid dynamic (CFD) modelling are described and experimental results are presented. Further experiments are designed and feasibility studies were performed
