Design and Development of Compact Chipless RFID Tags with High Data Encoding Capacity

The main objective of this thesis is to develop a compact chipless RFID tag with high data encoding capacity. The design and development of chipless RFID tag based on multiresonator and multiscatterer methods are presented first. An RFID tag using using SIR capable of 79bits is proposed. The thesis also deals with some of the properties of SIR like harmonic separation, independent control on resonant modes and the capability to change the electrical length. A chipless RFID reader working in a frequency band of 2.36GHz to 2.54GHz has been designed to show the feasibility of the RFID system. For a practical system, a new approach based on UWB Impulse Radar (UWB IR) technology is employed and the decoding methods from noisy backscattered signal are successfully demonstrated. The thesis also proposes a simple calibration procedure, which is able to decode the backscattered signal up to a distance of 80cm with 1mW output power.

Seismic behavior of capacity designed masonry walls in low seismicity regions

Eurocode 8 representing a new generation of structural design codes in Europe defines ‎requirements for the design of buildings against earthquake action. In Central and ‎Western Europe, the newly defined earthquake zones and corresponding design ground ‎acceleration values, will lead in many cases to earthquake actions which are remarkably ‎higher than those defined so far by the design codes used until now in Central Europe. ‎ In many cases, the weak points of masonry structures during an earthquake are the corner ‎regions of the walls. Loading of masonry walls by earthquake action leads in most cases ‎to high shear forces. The corresponding bending moment in such a wall typically causes a ‎significant increase of the eccentricity of the normal force in the critical wall cross ‎section. This in turn leads ultimately to a reduction of the size of the compression zone in ‎unreinforced walls and a high concentration of normal stresses and shear stresses in the ‎corner regions. ‎ Corner-Gap-Elements, consisting of a bearing beam located underneath the wall and ‎made of a sufficiently strong material (such as reinforced concrete), reduce the effect of ‎the eccentricity of the normal force and thus restricts the pinching effect of the ‎compression zone. In fact, the deformation can be concentrated in the joint below the ‎bearing beam. According to the principles of the Capacity Design philosophy, the ‎masonry itself is protected from high stresses as a potential cause of brittle failure. ‎ Shaking table tests at the NTU Athens Earthquake Engineering Laboratory have proven ‎the effectiveness of the Corner-Gap-Element. The following presentation will cover the ‎evaluation of various experimental results as well as a numerical modeling of the ‎observed phenomena.‎

Berufsanforderungen und flexible Altersgrenze

In 1973 the government of the Federal Republic plans to introduce a flexible retirement age. According to this new law, old age pensions can be paid already to people who are 63 years of age instead of 65 as at present. The government thus hopes to do more justice to the difference in capacity for work of elderly insured people and to the lact that the decline of life of humans depends to a certain extent on the occupational requirements demanded of them. Based on social science and medical research results this essay shows that the flexible retirement age cannot master these problems. The essay mentions in particular general relationships between age and work as well as special relationships between practised work, illness, disability and age. The bibliography includes literature connected with other aspects of the flexible retirement age.

Möglichkeiten zur Verwaltungsentwicklung auf der Basis einer Prozessgestaltung im IT-Labor, untersucht am Beispiel der Implementierung von E-Government bei der hessischen Landeshauptstadt Wiesbaden

In der vorliegenden Arbeit wird nach Wegen zur Steigerung der Effektivität von Implementationsprozessen umfassender IT-Anwendungen in großen Kommunalverwaltungen gesucht, da nach vorliegenden Schätzungen allenfalls 10 % der großen IT-Projekte der öffentlichen Verwaltungen zielkonform und erfolgreich umgesetzt werden. Analysen zeigen, dass die in solchen Prozessen auftretenden Interdependenzen von Technologie, Organisation und Mensch oft nicht angemessen berücksichtigt wurden. Die zentrale Fragestellung der vorliegenden Untersuchung lautet daher, ob ein IT-Labor mit einer vorgelagerten ablauforganisatorischen Prozessoptimierung im Sinne eines funktionalen Wirksamkeitstests mit einer ganzheitlichen Betrachtung von technologischen, organisatorischen und sozial-humanen Wirkungsfaktoren bei intensiver Einbeziehung von eigenem Personal der Anwendungsorganisation den Implementierungserfolg größerer IT-Vorhaben erhöhen kann. Als methodischer Ansatz wurde eine Fallstudie gewählt (Implementierung von eAkten und SOA). Der Implementierungsverlauf ist methodisch in eine vorgelagerte ablauforganisatorische Prozessoptimierung und in eine nachgelagerte informationstechnologische Umsetzungsphase (sog. IT-Labor) gegliedert. Die Fallstudie legt den Schluss nahe, dass ein IT-Labor mit einer vorgelagerten ablauforganisatorischen Prozessanalyse zum Erfolg der Implementation wesentlich beitragen kann. Zudem zeigte sich, dass eine serviceorientierte Architektur zur prozessorientierten ganzheitlichen technologischen Systemgestaltung die Integration vorhandener IT-Anwendungen fördern kann. Die beschriebene IT-Laborstrategie kann im Ergebnis als ein erprobter Weg zur erfolgreichen Implementierung komplexer IT-Vorhaben empfohlen werden. Aufgrund der Analyse können einige kritische Erfolgsfaktoren für einen späteren Produktivbetrieb identifiziert werden: - Eigene Personalressourcen mit den zugehörigen Lernprozessen sind unverzichtbar, - In diesem Kontext sind auch die zugehörigen organisatorischen und technologischen Voraussetzungen zu schaffen, - Eventuell auftretende Qualifikationsdefizite der Anwender können in Zusammenarbeit mit externen Unternehmen und IT-Dienstleistern im Verbund mit den eigenen Projektmitgliedern zeitnah kompensiert werden. Die angewandte Implementierungs-Methodik ist auf solche Fälle übertragbar, in denen eine Gebietskörperschaft ab der Aufgabenstruktur einer großen kreisfreien Stadt mit heterogenen und dezentralen IT- und Organisationsstrukturen unterschiedliche Fachverfahren in einem komplexen Verwaltungssystem ganzheitlich und prozessorientiert zusammenführen möchte. Grenzen können sich somit aus der Größe einer Gebietskörperschaft, dem konkreten Aufgabenprofil sowie der finanziellen Leistungsfähigkeit ergeben. Eine Transferfähigkeit unter sozialen Gesichtspunkten setzt voraus, dass neben externem Personal qualifiziertes internes Personal mit Fachwissen und Querschnitts-Know-How bereitgestellt wird. Räumlich und zeitlich setzt die Verallgemeinerungsfähigkeit eine analoge politische und administrative Struktur mit einem entsprechenden Entwicklungsstand voraus. Mit den Ergebnissen der vorliegenden Untersuchung können Behördenleiter, IT-Verantwortliche und Beratungsunternehmen künftig in vergleichbaren Fällen eine effektivere Implementierungsmethode wählen. In der weiteren verwaltungswissenschaftlichen Forschung auf diesem Gebiet können auf der Basis der vorgenommenen Untersuchung konkrete Erfahrungen zur IT-Implementierung erhoben und bewertet werden, um weitere Effektivitätsreserven zu identifizieren.

Evaluation of water retention capacity and flood control function of the forest catchment

This research quantitatively evaluates the water retention capacity and flood control function of the forest catchments by using hydrological data of the large flood events which happened after the serious droughts. The objective sites are the Oodo Dam and the Sameura Dam catchments in Japan. The kinematic wave model, which considers saturated and unsaturated sub-surface soil zones, is used for the rainfall-runoff analysis. The result shows that possible storage volume of the Oodo Dam catchment is 162.26 MCM in 2005, while that of Samerua is 102.83 MCM in 2005 and 102.64 MCM in 2007. Flood control function of the Oodo Dam catchment is 173 mm in water depth in 2005, while the Sameura Dam catchment 114 mm in 2005 and 126 mm in 2007. This indicates that the Oodo Dam catchment has more than twice as big water capacity as its capacity (78.4 mm), while the Sameura Dam catchment has about one-fifth of the its storage capacity (693 mm).

India’s Carbon Governance: The Clean Development Mechanism

Carbon Governance systems – institutional arrangements in place for mitigating greenhouse gas emissions – are different in emerging countries. Indeed, carbon is the same everywhere but Carbon Governance isn’t: in Brazil, the financial community is actively interested in carbon trading, but Chinese banks have hardly any interest in it; and while the Chinese government takes an active interest in providing capacity to project developers, the Brazilian authorities see their role uniquely as guarantors of environmental integrity of emissions reductions projects. In the case of India, carbon governance offers specific features of patterns and interactions mostly because India strongly developed the Clean Development Mechanism and its market. This article proposes a study to the research and understanding of how exactly carbon governance works in the Indian case, knowing that India is the second largest host of CDM projects.

The role of institutions as actors influencing Uganda’s cassava sector

We aim at mapping out a detailed framework that reveals the proportionate flow of cassava and its products along the value chain (VC). Furthermore, we aim at establishing the role of institutions and the linkages between institutions and other VC actors that influence the cassava VC in Uganda. We use both primary and secondary data obtained from four regions in Uganda. Results show that farmers, processors, transporters, traders, consumers and institutions are the major actors. There are four categories of institutions, viz, government, non-government, community based organisations and international agencies. Roles performed by institutions include: development and enforcement of policies, Research and Development (R&D), capacity building, and creation of market access linkages for cassava and its products. Findings reveal that there is no clear nexus and no coordination among farmers/producers, processors, traders, transporters and consumers. However, institutions are well coordinated and play various roles along the VC to influence the dynamics of actors. Policy-wise it is important to establish strong private-public partnerships to bridge the impaired linkages between the actors (farmers/producers, processors, traders, transporters, and consumers) and institutions. Strong partnerships are envisaged to reduce the associated transaction costs amongst the actors.

A Government-Binding Based Parser for Warlpiri, a Free-Word Order Language

Free-word order languages have long posed significant problems for standard parsing algorithms. This thesis presents an implemented parser, based on Government-Binding (GB) theory, for a particular free-word order language, Warlpiri, an aboriginal language of central Australia. The words in a sentence of a free-word order language may swap about relatively freely with little effect on meaning: the permutations of a sentence mean essentially the same thing. It is assumed that this similarity in meaning is directly reflected in the syntax. The parser presented here properly processes free word order because it assigns the same syntactic structure to the permutations of a single sentence. The parser also handles fixed word order, as well as other phenomena. On the view presented here, there is no such thing as a "configurational" or "non-configurational" language. Rather, there is a spectrum of languages that are more or less ordered. The operation of this parsing system is quite different in character from that of more traditional rule-based parsing systems, e.g., context-free parsers. In this system, parsing is carried out via the construction of two different structures, one encoding precedence information and one encoding hierarchical information. This bipartite representation is the key to handling both free- and fixed-order phenomena. This thesis first presents an overview of the portion of Warlpiri that can be parsed. Following this is a description of the linguistic theory on which the parser is based. The chapter after that describes the representations and algorithms of the parser. In conclusion, the parser is compared to related work. The appendix contains a substantial list of test cases ??th grammatical and ungrammatical ??at the parser has actually processed.

Benefits of Implementing Lean Practices and the Impact of the Lean Aerospace Initiative in the Defense Aerospace Industry and Government Agencies

In the 1980’s, many United States industrial organizations started developing new production processes to improve quality, reduce cost, and better respond to customer needs and the pressures of global competition. This new paradigm was coined Lean Production (or simply “Lean”) in the book The Machine That Changed The World published in 1990 by researchers from MIT’s International Motor Vehicle Program. In 1993, a consortium of US defense aerospace firms and the USAF Aeronautical Systems Center, together with the AFRL Materials and Manufacturing Directorate, started the Lean Aircraft Initiative (LAI) at MIT. With expansion in 1998 to include government space products, the program was renamed the Lean Aerospace Initiative. LAI’s vision is to “Significantly reduce the cost and cycle time for military aerospace products throughout the entire value chain while continuing to improve product performance.” By late 1998, 23 industry and 13 government organizations with paying memberships, along with MIT and the UAW were participating in the LAI.

Personnel Practices in Japanese Government

This paper examines key aspects of Japanese Government personnel practices, and draws comparisons with the practices in the U.S. civil service and, as appropriate, with other U.S. models. Particular reference is made to the practices of two major agencies in Japan, the Ministry of International Trade and Industry (MITI) and the Ministry of Posts and Telecommunications (MPT). As appropriate, selected government businesses practices other than personnel practices are noted.

Posibilidades de un proceso de paz en Colombia de conformidad con los principios de verdad, justicia y reparación : el caso de las AUC

Los países que salen de conflictos armados internos deben afrontar el reto de lograr el equilibrio entre los acuerdos para establecer la paz de un lado y la búsqueda de la justicia y la reconciliación de otro. En realidad, los procesos de justicia y reconciliación están bajo la influencia de numerosos factores entre los cuales se cuentan el impacto del conflicto, los recursos disponibles, el grado de voluntad política, la capacidad institucional, las normas legales, entre otros. En este contexto, la justicia transicional, la reparación, las reformas institucionales, la cooperación con la comunidad internacional y la búsqueda de una paz sostenible son temas importantes. Esta monografía se centra en el dilema entre el derecho de las víctimas a la justicia y el derecho a vivir en paz en un régimen democrático con base en el proceso que adelanta el Gobierno con grupos paramilitares.
