ALA's classic print publication, Guide to Reference Books, was replaced in 2009 with the online Guide to Reference. As the online introduction states, the web subscription version of the Guide to Reference serves as a gateway with interactive features that the former print guide never could have replicated. Indeed, because print publications are by their nature hampered by size limitations, the online guide simply can provide more cross referencing, offer more extensive comparative evaluations and annotations of sources, and become more global in coverage.

Abstract: The general report highlights the replies given to nine questions, by scholars from different legal systems. The problem of the fragmentation of international sources of law has been widely considered in the literature. It affects also the private law field. Judges and practitioners dealing with cross-border cases have to districate themselves between local rules on conflict of laws, international treaties on the law applicable to transnational relationships, conventions providing uniform material rules, and collections of principles by non-governmental organizations. The enquiry showed that the concern about the difficulty of districating this complex network of rules is mainly shown by academics. The supporting role of the executive (providing information about international obligations) is not everywhere reliable. Judges sometimes receive special training to tackle the increasing complexity of transnational law, but mostly in connection with EU law. The benefit that might be attached to a courts' specialization (in international commercial matters) is not as higly valued as to be implemented everywhere; the attitude of administrative, commercial, criminal courts is not perceived as highly diversified. In some countries the courts do adopt strategies to elude the difficulty (by a presumption of identity of the foreign sources with the local ones, by attaching a waiver of their rights to the parties' omission to plead the foreign law immediately, etc.). No definite suggestions on how to increase the awareness about the problem and how to face it seem easily available. Résumé: Le rapport général commente les réponses données par les rapporteurs nationaux à neuf questions concernant la complexité des sources transnationales. Le problème de la fragmentation des sources internationales du droit est discutée depuis de nombreuses années dans la littérature juridique: elle concerne aussi le droit privé. Les juges, les avocats, les praticiens du droit confrontés à des questions qui dépassent les frontières nationales doivent se débattre parmi les règles nationales de droit international privé, les traités internationaux concernant les conflits de lois, les conventions qui règlent de façon uniforme les rapports transnationaux, les innombrables principes issus d'organisations non gouvernementales. Les études entreprises dans ce secteur indiquent que le souci concernant la difficulté à s'orienter parmi cet ensemble inextricable de règles est exprimé principalement par le monde académique, tandis que le pouvoir exécutif (chargé d'informer les juristes sur les obligations internationals de l'Etat) ne joue pas toujours efficacement son rôle de support; une formation spéciale est offerte aux juges, mais surtout pour le droit de l'Union Européenne; l'avantage qui pourrait dériver d'une spécialisation des cours (en droit du commerce international) n'est pas considéré partout comme une nécessité; le comportement des tribunaux administratifs, criminels, commerciaux n'est pas perçu comme très différencié selon le sujet des sources transnationales. Les juges de certains pays mettent en oeuvre des stratégies pour contourner ces difficultés (en faisant recours à une presumption d'identité entre le droit étranger et le droit national, en présumant une renonciation à l'application du droit extra-national si les parties n'ont pas soulevé la question dès le début du procès, etc.). Il n'est pas aisé de formuler des suggestions sur la façon dont on pourrait augmenter la perception du problème ni sur la manière par laquelle on pourrait faire face à cette complexité croissante.

Annotation:
This thesis explores novel fibre-based coherent light source architectures and strategies for scaling output power. The research focuses on fibre-based amplified spontaneous emission (ASE) sources with broadband output in the ~1 μm spectral region and on internally-frequency-doubled fibre lasers emitting in the visible (green) wavelength range. In Part I: Spectrum-controllable fibre-based amplified spontaneous emission sources modelling, development and characterisation of a versatile ASE source based on Yb-doped fibre gain stages, using power-efficient means for spectrum control is presented. Experiments have culminated in a versatile seed source with polarized output and a reasonable degree of spectral control. In its final configuration, the ASE source was capable of producing either a broad spectrum in the 1-1.1 μm band with a full-width at half-maximum of 15-40 nm and output power > 1 W. Alternatively, single/multiple narrow lines with a full-width at half-maximum ranging from several nanometres to < 0.05 nm and output power spectral densities of up to 100 mW/nm could be generated. The output power was temporally stable with fluctuations at the level < 0.3-0.8% of the total output power. Very high spectral stability was obtained, which was limited mostly by the mechanical stability of the external cavity. The output beam was nearly diffraction limited with M2 ≈ 1.1. Part II: Efficient intracavity frequency doubling schemes for continuous-wave fibre lasers introduces a novel concept for resonant enhancement of the intracavity power in high power continuous-wave fibre lasers that is suitable for a wide range of applications. Using this concept, efficient frequency doubling in continuous-wave Yb-doped fibre lasers has been demonstrated and techniques for using it in devices based on both robustly single-mode and multi-mode fibres have been developed. Finally, this thesis presents wavelength tuning of continuous-wave Yb-doped fibre lasers over ~19 nm in the green spectral region and scaling the generated second harmonic power up to ~19 W with more than 21% pump to second harmonic conversion efficiency.

Dench, M. „Structural vibration control using multiple synchronous sources“. Thesis, University of Southampton, 2012. https://eprints.soton.ac.uk/349006/.

Der volle Inhalt der Quelle
Annotation:
The advantages of isolating vibrating machinery from its supporting structure are that the chances of vibration induced fatigue failure of structural components are reduced, the structure becomes more inhabitable for people due to less vibration exposure and the sound radiated by the structure into the environment is reduced. This last point is especially important for machinery operating in a marine environment because low frequency sound propagates very well underwater, and the machinery induced sound radiated from a ship or submarine is a primary detection and classification mechanism for passive sonar systems. This thesis investigates the control of vibration from an elastic support structure upon which multiple vibrating systems are passively mounted. The excitations are assumed to occur at discrete frequencies with a finite number of harmonic components and the machines are all assumed to be supplied with power from the same electrical supply. Active vibration control may be achieved by adjusting the phase of the voltage supplied to one or more of the machines, so that a minimum value of a measurable cost function is obtained. Adjusting the phase of a machine with respect to a reference machine is known as synchrophasing and is a well established technique for controlling the sound in aircraft cabins and in ducts containing axial fans. However, the use of the technique for reducing the vibration of machinery mounted on elastic structures seems to have received very little attention in the literature and would appear to be a gap in the current knowledge. This thesis aims to address that gap by investigating theoretically and experimentally how synchrophasing can be implemented as an active structural vibration control technique.

This thesis performs probabilistic analyses of the depth of digital trees [tries and digital search trees (dst)] when they are built on words emitted by a general source. This study is related to compression algorithms of Lempel-Ziv type which are based on the use of digital trees (tries or dst). The complexity of algorithms which use these data structures are related to the shape of these trees, and we are here interested by the probabilistic behaviour of an important parameter, the typical depth, or depth. We introduce a new point of view on general sources, and we then focus on the model of dynamical sources. The source intervenes in the analysis via its tameness, and we define precise notions of tameness which are new. The thesis deals with methods in analytic combinatorics, and we introduce (Dirichlet) generating functions, which characterize the behaviour of the tree (trie or dst) when it is built on the source. As the source is a dynamical source, we perform a dynamical analysis, which mixes in an original setting method from analytic combinatorics and methods from dynamical system theory (namely transfer operators, and their spectral properties). We also use many objects and methods from classical analytic combinatorics, as Poisson, Laplace, and Mellin transforms, that we mix in a new way. We also provide an unified point of view on the analysis of the two types of digital trees (tries and dst), whereas the classical analyses are dedicated to one of the precise types of trees. Finally, we prove that, for the two types of digital trees, for a large class of sources, the typical depth follows an asymptiotic gaussian law, with an optimal speed of convergence

Annotation:
This thesis reports on theoretical and experimental studies of wavelength-selective waveguide structures for high-power Nd3+- and Yb3+-doped fibre lasers. Cladding-pumped high-power fibre lasers based on these novel waveguide designs and operating at desired unconventional wavelengths were investigated through numerical simulations and fibre laser experiments. Rare earth doped fibres have typically multiple emission bands of different effective strengths. Stimulate emission from strong bands dominates over, and via a reduced population inversion normally even suppresses, emission from weaker bands in conventional step-index waveguides. For efficient emission and laser operation on the weaker emission bands, it is necessary to suppress unwanted stimulated emission on the strong transitions by preventing power from building up at the unwanted wavelengths. Discrete "bulk" (non-waveguide) devices at a single or a few points are ineffective, if the gain at unwanted wavelength is sufficiently high to generate high-power amplified spontaneous emission even between filters. In such cases, waveguide structures which reduce the gain at unwanted wavelengths and prevent build-up of unwanted emission can be considered. The fibre itself acts as a distributed wavelength-selective filter, and a compact all-fibre laser can be made. For short-wavelength operation when the gain at longer wavelengths needs to be suppressed, a helical core fibre is proposed. This induces a large bending loss at unwanted longer wavelengths while the bending loss at desired shorter wavelength remains relatively low. The required bending loss properties, for efficient operation at the desired shorter wavelength, can be achieved by designing the helix pitch and offset along with fibre core diameter and NA (numerical aperture). A Nd3+-doped helical fibre laser operating at 0.92 μm was investigated through computer simulations. Alternatively, there are fibres in which the fundamental mode can be cut off at a certain wavelength. I have studied fibres with a W-type refractive index profile and fibres with a hollow (air-filled) central region surrounded by a core and then a region with depressed refractive index, known as depressed-clad hollow fibre. With these fibre designs, the doped core guides the desired shorter wavelength but not the unwanted longer wavelengths. Nd3+-doped W-type fibre lasers operating at 0.92 μm were simulated and experimentally demonstrated. Also Yb3+-doped depressed-clad hollow fibre lasers operating at 0.98 μm were simulated and experimentally demonstrated. For long wavelength operation, with a suppressed gain at shorter wavelengths, modified W-type designs are proposed. By designing the refractive index profile and using ring-shaped gain regions, the net gain on an intrinsically weak long-wavelength transition may become larger than that on an intrinsically stronger short-wavelength transition. Adopting this technique, Nd3+-doped fibre amplifiers and lasers operating at 1.38 μm were simulated. While fibre lasers that generate a nearly diffraction-limited single-mode beam are normally targeted, a multimode output is often obtained, e.g., in development stages with nonideal fibres. Then it is important to characterise the modal properties of the beam. For this, two different modal power decomposition methods based on intensity measurements are proposed. The first method is based on a tomography technique that uses a Wigner function followed by an inverse Radon transform. The second method adopts a wavelength-sweeping optical source which induces beat patterns after propagation through a certain length of fibre. The feasibilities of the two proposed ideas were verified through numerical simulations.

Annotation:
Terahertz (THz) technology has been generating a lot of interest because of the potential applications for systems working in this frequency range. However, to fully achieve this potential, effective and efficient ways of generating controlled signals in the terahertz range are required. Devices that exhibit negative differential resistance (NDR) in a region of their current-voltage (I-V ) characteristics have been used in circuits for the generation of radio frequency signals. Of all of these NDR devices, resonant tunneling diode (RTD) oscillators, with their ability to oscillate in the THz range are considered as one of the most promising solid-state sources for terahertz signal generation at room temperature. There are however limitations and challenges with these devices, from inherent low output power usually in the range of micro-watts (uW) for RTD oscillators when milli-watts (mW) are desired. At device level, parasitic oscillations caused by the biasing line inductance when the device is biased in the NDR region prevent accurate device characterisation, which in turn prevents device modelling for computer simulations. This thesis describes work on I-V characterisation of tunnel diode (TD) and RTD (fabricated by Dr. Jue Wang) devices, and the radio frequency (RF) characterisation and small signal modelling of RTDs. The thesis also describes the design and measurement of hybrid TD oscillators for higher output power and the design and measurement of a planar Yagi antenna (fabricated by Khalid Alharbi) for THz applications. To enable oscillation free current-voltage characterisation of tunnel diodes, a commonly employed method is the use of a suitable resistor connected across the device to make the total differential resistance in the NDR region positive. However, this approach is not without problems as the value of the resistor has to satisfy certain conditions or else bias oscillations would still be present in the NDR region of the measured I-V characteristics. This method is difficult to use for RTDs which are fabricated on wafer due to the discrepancies in designed and actual resistance values of fabricated resistors using thin film technology. In this work, using pulsed DC rather than static DC measurements during device characterisation were shown to give accurate characteristics in the NDR region without the need for a stabilisation resistor. This approach allows for direct oscillation free characterisation for devices. Experimental results show that the I-V characterisation of tunnel diodes and RTD devices free of bias oscillations in the NDR region can be made. In this work, a new power-combining topology to address the limitations of low output power of TD and RTD oscillators is presented. The design employs the use of two oscillators biased separately, but with the combined output power from both collected at a single load. Compared to previous approaches, this method keeps the frequency of oscillation of the combined oscillators the same as for one of the oscillators. Experimental results with a hybrid circuit using two tunnel diode oscillators compared with a single oscillator design with similar values shows that the coupled oscillators produce double the output RF power of the single oscillator. This topology can be scaled for higher (up to terahertz) frequencies in the future by using RTD oscillators. Finally, a broadband Yagi antenna suitable for wireless communication at terahertz frequencies is presented in this thesis. The return loss of the antenna showed that the bandwidth is larger than the measured range (140-220 GHz). A new method was used to characterise the radiation pattern of the antenna in the E-plane. This was carried out on-wafer and the measured radiation pattern showed good agreement with the simulated pattern. In summary, this work makes important contributions to the accurate characterisation and modelling of TDs and RTDs, circuit-based techniques for power combining of high frequency TD or RTD oscillators, and to antennas suitable for on chip integration with high frequency oscillators.

The smuggling of illicit goods poses a significant threat to the safety, security and economy of all nations. Undeclared black market goods, illegal narcotics and weapons are all threats that could ideally be prevented from crossing national borders. At present cargo interrogation is primarily performed using X-rays, which can be defeated by effective shielding and disguising of objects. Neutron interrogation offers an additional line of defence against smuggling, and there are a number of techniques available, which are discussed in this thesis. In this thesis a review of the limitations of current cargo interrogation technology is given. Current technology has limitations, and these are considered. In preparation of this thesis Monte-Carlo transport codes MCNPX and Geant4 were used as well as nuclear inventory code EASY-II, and a description of their key features is given. The possible methods of interrogating cargo with neutrons is discussed. Cargo can be interrogated with a range of neutron spectra, and either the neutrons or the produced gammas can be used. The use of techniques based on detecting neutrons or gammas is discussed, and simulations of gamma production by fast inelastic neutron scattering are presented. This is followed by a review of the principles of compound nucleus based neutron sources. The produced neutron spectra and the decay isotopes are both important considerations, and the results of possible combinations of target and projectile are given. Use of deuterons to produce neutrons through compound nucleus reactions has potential, due to the high Q of some reactions. If deuterons are used there is also a possibility of dissociation, if kinetic energies above the binding energy are used. At present deuteron dissociation cannot be simulated in Geant4 or MCNPX. Two new models of deuteron dissociation, one high and one low precision, have been developed for inclusion in Geant4. The physics and operation of these models is discussed and comparison with experimental data is presented. When interrogating cargo with neutrons it is unavoidable that some level of activation will occur. In particular the activation of food is of significant concern due to the exposure caused by ingestion. To date there has been little investigation of the activation of cargo under neutron interrogation. By using up to date nuclear data libraries and numerical techniques it was possible to extend early work in this field. In addition it is claimed in literature that 24N a is the only isotope of concern, this is shown to only be valid for certain combinations of food composition and irradiating energy.

Annotation:
The proliferation of mobile technologies in the general population offers new opportunities for survey research, but also introduces new sources of error to the data collection process. This thesis studies two potential sources of error in mobile survey data collection: measurement error and nonresponse. Chapter 1 examines how the diagonal screen size of a mobile device affects measurement error. Using data from a non-mobile-optimised web survey, I compare data quality between screen size groups. Results suggest that data quality mainly differs between small smartphones with a screen size of below 4.0 inches and larger mobile devices. Respondents using small smartphones are more likely to break off during the survey, to provide shorter answers to open-ended questions, and to select fewer items in check-all-that-apply questions than respondents using devices with larger screens. Due to the portability of mobile devices, mobile web respondents are more likely to be in distracting environments where other people are present. Chapter 2 explores how distractions during web survey completion influence measurement error. I conducted a laboratory experiment where participants were randomly assigned to devices (PC or tablet) and to one of three distraction conditions (presence of other people who have a loud conversation, presence of music, or no distraction). Although respondents felt more distracted in the two distraction conditions, I did not find significant effects of distraction on data quality. Chapter 3 investigates correlates of nonresponse to data collection using mobile technologies. We asked members of a probability household panel about their willingness to participate in various data collection tasks on their mobile device. We find that willingness varies considerably by the type of activity involved, to some extent by device, and by respondent: those who report higher security concerns and who use their device less intensively are less willing to participate in mobile data collection.

Annotation:
This doctoral study discusses how to control fluctuating renewable energy sources at converter, unit, and system layers to deliver smoothed power output to the grid. This is particularly relevant to renewable power generation since the output power of many kinds of renewable energy sources have huge fluctuations (e.g. solar, wind and wave) that needs to be properly treated for grid integration. In this research, the energy quality is developed to describe the friendliness and compatibility of power flows/waveforms to the grid, by contrast with the well-known concept of power quality which is used to assess the voltage and current waveforms. In Chapter 1 & 2, a background introduction and a literature review of studied subjects are presented, respectively. In Chapter 3, the problem of determining the PI parameters in dq decoupling control of voltage source converter (VSC) is studied based on a state-space model. The problems of the conventional method when there is insufficient interface resistance are addressed. New methods are proposed to overcome these drawbacks. In Chapter 4 & 5, energy quality and the energy filters (EFs) are proposed as tools to assess and manage power fluctuations of renewable energy sources. The proposed EFs are energy storage control systems that could be implemented on a variety of energy storage hardware. EFs behave like low-pass filters to the power flows. Finally, in Chapter 6, as an application example of renewable power plant with energy filter control and smoothed power output, a master-slave wave farm system is proposed. The wave farm system uses enlarged rotor inertia of electric machines as self-energy storage devices.

Alexander, David Alisdair. „The sources of committee influence in the European Parliament“. Thesis, University of Glasgow, 2016. http://theses.gla.ac.uk/8281/.

Der volle Inhalt der Quelle
Annotation:
The European Parliament (EP) has evolved into a powerful legislative actor over the past 40 years. In order to exercise its hard won legislative competencies in an efficient and effective manner the EP has developed an extensive and influential committee system. The Treaty of Lisbon (ToL) recognised its equal status as co-legislator with the Council of the EU and introduced the Ordinary Legislative Procedure (OLP) as the default EU legislative procedure. Despite the fact that after the introduction of the OLP all EP committees formally operate under the same legal procedure, disparities remain in the levels of influence that each committee commands. This state of affairs demonstrates that if we are to understand what drives committee influence we need to explore the informal sources of influence that committees draw on in addition to the formal rules. This project addresses the lack of understanding of how the committees establish legislative influence by identifying and testing the different resources which committees may be utilising to establish their influence. The thesis puts forward four hypotheses concerning the factors that can account for how committees establish influence. These are developed and tested within three case studies. The case studies comprise the highly influential committees on, firstly, the Environment, Public Health and Food Safety Committee, secondly, the Budget Committee and, thirdly, the International Trade Committee. The research project adopts a qualitative approach to complement and create a different perspective from the quantitative studies which dominate the field. It draws on extensive primary material from thirty semi-structured interviews held with MEPs, advisers, EP staff and party officials active in the 7th legislative term (2009-2014). A number of the current conventions concerning the way in which expertise, partisan dynamics, and policy outputs affect how committees establish legislative influence are challenged and new insights regarding their relative importance are offered. Overall, these original findings, contained within this dissertation, have highly significant implications, not only with regard to the committee system of the EP but, also, for the wider field of legislative politics.

Balasiny, Basema Kasem. „Regulation and sources of nitric oxide in Escherichia coli“. Thesis, University of Birmingham, 2016. http://etheses.bham.ac.uk//id/eprint/6748/.

Der volle Inhalt der Quelle
Annotation:
The enteric bacterium \(Escherichia\) \(coli\) is exposed to nitric oxide (NO) in its oxygen-limited environment. Various transcription factors regulate gene expression to provide protection against nitrosative stress, but their respective roles remain controversial. Key questions answered in this thesis were whether S-nitrosylated OxyR directly regulates the expression of NO-regulated genes; whether NsrR is required for the synthesis of an important protective system; and whether FNR is a physiologically relevant sensor of environmental NO. Transcription from the NO-activated \(hcp\) promoter was almost totally dependent upon a functional FNR protein, which is inactivated by oxidative stress, but unaffected by deletion of the \(oxyR\) gene. This indicated that the effects of an \(oxyR\) mutation on resistance to nitrosative stress are indirectly due to inactivation of FNR rather than to direct activation of \(hcp\) transcription by S-nitrosylated OxyR. The NO-sensitive repressor, NsrR, is not essential for protection against nitrosative stress. Nitric oxide produced during nitrite reduction had no effect on the ability of FNR to activate or repress gene expression, which is primarily due to NO sensing by NsrR, not by FNR. Some NO accumulates in the \(E. coli\) cytoplasm even in mutants that lack known sources of NO. The source of most of this residual NO is the NsrR-regulated protein, YtfE. Contrary to the proposal by others that YtfE repairs iron-sulfur centres by replacing iron atoms released during nitrosative stress, it is proposed that YtfE releases NO from nitrosylated iron-sulfur proteins, and that Hcp reduces this NO to the less toxic N2O.

Annotation:
This paper describes a novel, dynamic, forward-looking applied general equilibrium model of Saudi Arabia that represents interactions between the energy sectors and the rest of the economy. This model serves to produce long-term scenarios that describe possible energy transition trajectories in terms of policies, emissions, and economic impacts. This model covers all the sources of greenhouse gas emissions and features several emission reduction technologies and a representation of hydrogen supply and demand. We explain the overall structure of the model and how the different energy demand technologies are represented. We also describe the linkages with the rest of the world through trade in energy commodities.

The following pages describe initial findings from the first of four surveys administered in a state of the field study as part of the Modeling Zoos and Aquariums as Inclusive Communities of Science (MoZAICS) for Autistic Individuals project. This study was designed to look across the Association of Zoos and Aquariums (AZA) field to understand what inclusive practices zoos and aquariums are currently using to support autistic individuals across the full zoo/aquarium experience (e.g., general visit, programs, events, design of learning experiences, volunteering, internships and employment). In the first survey, zoo and aquarium employees responded to open- and closed-ended prompts that asked respondents to reflect on their organization’s current practices for supporting the inclusion of autistic individuals across four areas: the general visit; spaces for exhibiting, learning or working; human resources; and leadership. Additional questions asked respondents about their site’s partnerships with autism-related communities (e.g., autistic self-advocates, community-based advocacy groups).

Annotation:
CGE models are utilized for the evaluation of trade policy reforms, yet they are typically highly aggregated, limiting their usefulness to trade negotiators interested in impacts at the tariff line. Partial Equilibrium (PE) models used for disaggregate analysis lack the benefits of an economy-wide analysis required to examine the overall impact of trade policy reforms. This suggests the need for a PE-GE, nested modeling framework to support trade policy analysis. In this paper, we develop a PE model that captures international trade, domestic consumption and output, using CET and CES structures, market clearing conditions and price linkages, nested within the standard GTAP Model. In addition, we extend the welfare decomposition of Huff and Hertel (2001) to this PE-GE model to contrast the sources of welfare gain among models. To illustrate the value-added of this model, we examine the impact of multi-lateral tariff liberalization on the Indian economy, with special focus on the auto sector, using PE, GE and PE-GE models. The PE model does not predict the change in overall size and price level for the industry well, while the GE model underestimates the aggregate welfare gain due to tariff averaging. It also fails to account for the change in industry composition resulting from trade reform. These findings are robust to wide variation in model parameters. We conclude that the linked model is superior to both the GE and PE counterparts.

Annotation:
Computable General Equilibrium (CGE) models have been widely used for quantitative analysis of global economic issues. However, CGE models are frequently criticized for resting on weak empirical foundations. This paper builds on recent work in macro-econometric estimation, developing an approach to parameter estimation for a widely employed global CGE model, the Global Trade Analysis Project (GTAP) model. An approximate likelihood function is developed and the set of optimum elasticity values is obtained by maximizing this approximate likelihood function in the context of a back casting exercise. In addition, two statistical tests are performed. The first of these tests compares the standard GTAP elasticity vector with the estimated trade elasticity vector. It rejects the null hypothesis of equality between the two sets of trade elasticities. The second test examines the widely maintained hypothesis known as the “rule of two”, by which the elasticity of substitution across imports by sources is set equal to twice the elasticity of substitution between domestic goods and imports. We fail to reject this common rule of thumb. We conclude that there is much to be gained by nesting CGE models within an estimation framework as this opens the way for formal evaluation of model performance and parameterization.
