Sparsity-aware multiple relay selection in large multi-hop decode-and-forward relay networks
2016
In this paper, we propose and investigate two novel techniques to perform multiple relay selection in large multi-hop decode-and-forward relay networks. The two proposed techniques exploit sparse signal recovery theory to select multiple relays using the orthogonal matching pursuit algorithm and outperform state-of-the-art techniques in terms of outage probability and computation complexity. To reduce the amount of collected channel state information (CSI), we propose a limited-feedback scheme where only a limited number of relays feedback their CSI. Furthermore, a detailed performance-complexity tradeoff investigation is conducted for the different studied techniques and verified by Monte …

Wola mocy w architekturze. Inspiracje Nietzscheańskie
2021
Po przedstawieniu swej interpretacji greckiej tragedii, w której współdziałają apollińskość i dionizyjskość, Nietzsche koncypował całościową teorię sztuki, w której zasadniczą rolę odgrywa wola mocy. Coraz bardziej pociągała go też idea architektury jako sztuki tworzonej z woli mocy i obejmującej najwyższe dążenia człowieka. Można przyjąć, że w przestrzeni architektonicznej apollińskość jest pięknem, a dionizyjskość jest wzniosłością. Oba żywioły dialektycznie syntetyzują się w postaci woli mocy będącej najpotężniejszą formą żywiołowości. Właśnie ona powołuje do życia wielką sztukę, która wspiera człowieka w jego przeobrażaniu się w nadczłowieka. Aby ta przemiana ontologiczna doszła do skut…
Representations of the Life-giving Spring feast in Romanian iconography
2021
This article explores the development of the theme of the Life-giving Spring in Byzantine iconography. The path towards its establishment was initiated at the moment when a representation rule, an original convention was set. Thereafter, because of its diffusion in time and space, the theme became enriched by particular mentalities and sensibilities of the epochs and the communities that adopted it as a form of devotion for the Virgin Theotokos. As a result, the representations we have known so far are extremely varied. Contribution: The final purpose of this approach, as well as its contribution, is to highlight the diverse unity of the iconographic tradition and illustrate both the evolut…
Modelli lignei e architettura in Sicilia tra XV e XVI secolo
2020
La realizzazione di modelli lignei nel processo di creazione di opere architettoniche in Sicilia è documentata a partire dalla fine del XV secolo. Oltre ad alcune testimonianze nel campo dell’architettura militare, si tratta principalmente di edifici chiesastici, nei quali una articolata committenza svolge un ruolo propositivo. Nell’ambito delle comunità benedettine, in particolare, trova riscontro l’esistenza di un modus operandi che include la realizzazione di modelli lignei. Da tale modalità operativa, tuttavia, non rimane esclusa l’architettura civile. Questo contributo analizza le testimonianze relative a tale casistica, valutando l’attendibilità per il contesto in esame dei parametri …
Los paisajes de la globalización, la elección de la ciudad-expo 2008. ¿Qué pasa con la gobernanza urbana frente a las estrategias económicas y espaci…
2005
Am 16. Dezember 2004 wählte das Bureau international des expositions (B.I.E.) Spanien und seine Kandidatenstadt, die Metropole Saragossa, als Organisationsland für die nächste internationale Ausstellung „International Exhibition of Zaragoza Spain 2008: Water and Sustainable Development“. Wir analysieren zunächst die Entwicklung "der Wege" der Kandidaturen zur Wahl der Gastgeberstadt der Internationalen Ausstellung 2008, dann greifen wir in einem zweiten Mal den gesamten Vorgang der Ausarbeitung, Begründung und Durchführung der Internationalen Ausstellung 2008 in Saragossa auf im Kontext der Globalisierung neue städtische Formen und Formen des Regierens hervorbringen, indem alle finanziellen…
Enterprise Architecture : A Perspective on How Far We Have Come, and Directions for the Future
2019
Enterprise Architecture (EA) appears to retain the attention of both practitioners and researchers, as the technological complexity of organizations grows. Several researchers have noted that research on EA has been diversifying over time, leading to inconsistent use of terminologies. Further, the benefit claims and other results, rather frequently, are not based on empirical evidence. These shortfalls in research on EA impede EA from maturing as a discipline and from demonstrating its benefit claims. Although there are reasons to believe that the research on EA has progressed, the extent of the progress and the directions for future research are not evident. This study draws on a meta-revi…
Towards a Contingency Framework for Engineering an Enterprise Architecture Planning Method
2007
Enterprise architecture (EA) has a key role in managing and relating business strategies and processes, information systems, and IC technologies. EA planning devises an EA plan with development steps to make necessary enhancements to the current state of the affairs in EA. Accomplishing EA planning in a systematic and efficient manner requires the availability of frameworks and methods suitable to the situation at hand. The selection and adaptation of these methodical artifacts for the use of EA planning is often quite challenging in practice. We argue that the contingency approach can help in these activities of method engineering (ME), and present a contingency framework (named here EACon…
Technology Architecture as a Driver for Business Cooperation: Case Study - Public Sector Cooperation in Finland
2019
The current premise in the enterprise architecture (EA) literature is that business architecture defines all other EA architecture layers; information architecture, information systems architecture, and technology architecture. In this paper, we will study the ICT-cooperation between eight small and mid-sized municipalities and cities in Southern Finland. Our case demonstrates that the ICT-cooperation is possible without business cooperation and that ICT-cooperation can be a driver for future business cooperation. The findings challenge the current premise of the guiding force of the business architecture and encourage organisations’ ICT-functions to seek daringly cooperation with other org…
Systems Approaches in the Enterprise Architecture Field of Research: A Systematic Literature Review
2018
This study explores the use of the systems approaches (systems thinking and systems theories) as the theoretical underpinnings for Enterprise Architecture (EA) research. Both the academic and the practitioner communities have maintained an interest in EA due to its potential benefits, promising for the recent technological and business advances. EA as a research area is, however, characterized by diversified views depicted in different definitions of the concept, and no acknowledged common theoretical foundation. A number of prior studies have noticed this gap in the EA field of research, and called for a strengthening of the theory of EA. Variegated systems approaches have been suggested a…
