description: The inversion layer (IL) of a clear-sky, buoyancy-driven convective boundary layer is investigated using large-eddy simulations covering a wide range of convective Richardson numbers. A new model of the IL is suggested and tested. The model performs better than previous first-order models of the entrainment and provides physical insights into the main controls of the mixed-layer and IL growths. A consistent prognostic equation of the IL growth is derived, with explicit dependence on the position of the minimum buoyancy flux, convective Richardson number and relative stratification across the inversion G. The IL model expresses the interrelationship between the position and magnitude of the minimum buoyancy flux and inversion layer depth. These relationships emphasize why zero-order–jump models of the convective boundary layer perform well under a strong inversion and show that these models miss the additional parameter, G, the relative stratification across the inversion to fully characterize the entrainment process under a weak inversion. Additionally, the position of the minimum buoyancy flux within the new IL model is shown to be a key component of convective boundary layer entrainment. The new IL model is sufficiently simple to be used in numerical weather prediction or general circulation models as a way to resolve the IL in a low vertical resolution model.
Motor Imagery in Perception and Performance of Sound and Music

Sound Perception

description: Jan Schacher asks what it is to imagine and initiate an action on a musical instrument. For Schacher, the body is the central element of listening and sound perception, and thus the body, in an embodied and enactive sense, becomes the focus for 'musicking' with both conventional instruments and digital instruments, where, in the latter case, bodily schemata are replaced by metaphors and instrumental representations. This last theme provides a significant topic of enquiry in the chapter, and it is explored from a number of angles, chief among which is a focus (through the lenses of motor imagery and imagination in music) on relations between inner and outer aspects of our ways and means of listening to and performing both music and sound. Ultimately, Schacher identifies a tension underlying digital musical performance brought about by the fracturing of the 'action-sound' bond, a bond that is the basis not only for our sonic perception of the natural world but also of the world of culturally defined musical performance.

Debussy as Storyteller: Narrative Expansion in the Trois Chansons de Bilitis
Creators: name: Gibbons, William
Publisher: name: Columbia University
Year: 2008
Subjects: Music

description: Every song cycle presents its audience with a narrative. Such an idea is hardly new; indeed the idea of an unfolding plot or unifying concept (textual or musical) is central to the concept of the song cycle as opposed to a collection of songs, at least after the mid-nineteenth century. A great deal of musicological literature devoted to song cycles is aimed at demonstrating that they are cohesive wholes, often connected both musically by means of key relationships, motivic recall, and similar techniques , and textually, by means of the creation of an overarching plot or concept. One type of narrative results from a poetic unit being set to music in its complete state, without alteration. In an effort to demonstrate the internally cohesive qualities of these song cycles, typical analyses assume that the narrative is contained entirely with the musical cycle itself- that is, that it makes no external references.

description: Efficient methods for describing non abelian charges in worldline approaches to QFT are useful to simplify calculations and address structural properties, as for example color/kinematics relations. Here we analyze in detail a method for treating arbitrary non abelian charges. We use Grassmann variables to take into account color degrees of freedom, which however are known to produce reducible representations of the color group. Then we couple them to a U(1) gauge field defined on the worldline, together with a Chern-Simons term, to achieve projection on an irreducible representation. Upon gauge fixing there remains a modulus, an angle parametrizing the U(1) Wilson loop, whose dependence is taken into account exactly in the propagator of the Grassmann variables. We test the method in simple examples, the scalar and spin 1/2 contribution to the gluon self energy, and suggest that it might simplify the analysis of more involved amplitudes.

description: We demonstrate a high bit-rate quantum random number generator by interferometric detection of phase diffusion in a gain-switched DFB laser diode. Gain switching at few-GHz frequencies produces a train of bright pulses with nearly equal amplitudes and random phases. An unbalanced Mach-Zehnder interferometer is used to interfere subsequent pulses and thereby generate strong random-amplitude pulses, which are detected and digitized to produce a high-rate random bit string. Using established models of semiconductor laser field dynamics, we predict a regime of high visibility interference and nearly complete vacuum-fluctuation-induced phase diffusion between pulses. These are confirmed by measurement of pulse power statistics at the output of the interferometer. Using a 5.825 GHz excitation rate and 14-bit digitization, we observe 43 Gbps quantum randomness generation.
Review of Herbert Hochberg and Kevin Mulligan (eds.), Relations and Predicates [Frankfurt, Ontos Verlag, 2004]

subject: FOS: Philosophy, ethics and religion

description: As the title suggests, Relations and Predicates deals mainly with the problem of universals, with special reference to the issues raised by relational predication. Some of the essays explore aspects of the history of these issues while others take up a number of questions that feature prominently in the current debate, such as the prospects of trope theory, Bradley’s regress, or the problem of order in relational facts. The volume, however, also includes essays that are only marginally connected to these central issues (such as the transitivity of the part-whole relation) or completely off the point (the seeming paradoxicality of certain contingent analytic falsehoods, such as ‘I am not here’), so the overall collection is somewhat incohesive. As to quality, the heterogeneity is even more noticeable. There are some good contributions—and we’ll come to those in a moment; but there are also essays that deserve no place in a respectable collection. In spite of the heterogeneity and unevenness of the ten essays that it collects, the volume as a whole has more than enough good things to offer. With some editorial supervision, a solid introduction, and perhaps a contribution by the second editor—whose work on formal relations has helped shape the current debate on many a topic touched on by these essays—Relations and Predicates could have been a very good book.

description: Remaining liberties that GDPR provides to EU Member States, as well as remaining ambiguities on GDPR interpretation, continue to feed debates in the ethical and legal literature. Projects like CINECA, which is seeking to facilitate health data exchanges between cohorts in Europe, Canada and Africa, offer valuable experience and input on essential ethical and legal gaps between countries and cohorts on questions such as the ethical lawful basis for international health data sharing and secondary processing for research purposes. The focus of this deliverable will be on answering, both from a legal and an ethical point of view, two priority questions: How to choose a legal basis for CINECA’s data processing? And how should CINECA apprehend broad consent to further data processing? The goal will be to study how the CINECA project could be efficiently conducted (especially data sharing) while being legally compliant with relevant laws and regulations across all member states, and most of all, being compliant with established ethical guidelines and practices across three continents. To answer these questions we have conducted research which has consisted in reviewing GDPR provisions and their institutional sources of interpretation; the corresponding legal and ethical literature; the National laws relevant for the cohorts involved in CINECA as well as cohorts’ internal governance frameworks and privacy policies when available. We present the arguments surrounding the use of GDPR legal exemptions for data processing for scientific research purposes, why researchers are wary to use it for ethical reasons related to the absence of consent, and the practicalities of the use of broad consent for secondary data processing. We recommend using the research exemption as a lawful basis for secondary data processing; Add broad consent as an appropriate safeguard for data subjects’ rights; Restrict the use of the research exemption to research conducted in the “public interest” as defined by National laws. 
The structure and fate of white dwarf merger remnants

description: We present a large parameter study where we investigate the structure of white dwarf (WD) merger remnants after the dynamical phase. A wide range of WD masses and compositions are explored and we also probe the effect of different initial conditions. We investigated the degree of mixing between the WDs, the conditions for detonations as well as the amount of gas ejected. We find that systems with lower mass ratios have more total angular momentum and as a result more mass is flung out in a tidal tail. Nuclear burning can affect the amount of mass ejected. Many WD binaries that contain a helium-rich WD achieve the conditions to trigger a detonation. In contrast, for carbon-oxygen transferring systems only the most massive mergers with a total mass above ~2.1 solar masses detonate. Even systems with lower mass may detonate long after the merger if the remnant remains above the Chandrasekhar mass and carbon is ignited at the centre. Finally, our findings are discussed in the context of several possible observed astrophysical events and stellar systems, such as hot subdwarfs, R Coronae Borealis stars, single massive white dwarfs, supernovae of type Ia and other transient events. A large database containing 225 white dwarf merger remnants is made available via a dedicated web page.

description: We present a numerical study of electromagnetic wave transport in disordered quasi-one-dimensional waveguides at terahertz frequencies. Finite element method calculations of terahertz wave propagation within LiNbO$_{3}$ waveguides with randomly arranged air-filled circular scatterers exhibit an onset of Anderson localization at experimentally accessible length scales. Results for the average transmission as a function of waveguide length and scatterer density demonstrate a clear crossover from diffusive to localized transport regime. In addition, we find that transmission fluctuations grow dramatically when crossing into the localized regime. Our numerical results are in good quantitative agreement with theory over a wide range of experimentally accessible parameters both in the diffusive and localized regime opening the path towards experimental observation of terahertz wave localization.

description: The electron-phonon interaction is a major factor influencing the competition between collective instabilities in correlated-electron materials, but its role in driving high-temperature superconductivity in the cuprates remains poorly understood. We have used high-resolution inelastic x-ray scattering to monitor low-energy phonons in YBa$_2$Cu$_3$O$_{6.6}$ (superconducting $\bf T_c = 61$ K), which is close to a charge density wave (CDW) instability. Phonons in a narrow range of momentum space around the CDW ordering vector exhibit extremely large superconductivity-induced lineshape renormalizations. These results imply that the electron-phonon interaction has sufficient strength to generate various anomalies in electronic spectra, but does not contribute significantly to Cooper pairing. In addition, a quasi-elastic "central peak" due to CDW nanodomains is observed in a wide temperature range above and below $\bf T_c$, suggesting that the gradual onset of a spatially inhomogeneous CDW domain state with decreasing temperature is a generic feature of the underdoped cuprates.

In the first, we implement a spin-3/2 Majorana gravitino field, as in local supersymmetric models, and study gravitino and gluino pair-production. In the second, a spin-3/2 Dirac top-quark excitation, inspired from compositness models, is implemented. We then investigate both top-quark excitation and top-quark pair-production. In the third, a general effective operator for a spin-3/2 Dirac quark excitation is implemented, followed by a calculation of the angular distribution of the s-channel production mechanism.

On Classical Solvability for a Linear 1D Heat Equation with Constant Delay

Publisher: name: arXiv
Year: 2014
Subjects: subject: Analysis of PDEs (math.AP)

description: In this paper, we consider a linear heat equation with constant coefficients and a single constant delay. Such equations are commonly used to model and study various problems arising in ecology and population biology when describing the temporal evolution of human or animal populations accounting for migration, interaction with the environment and certain aftereffects caused by diseases or enviromental polution, etc. Whereas dynamical systems with lumped parameters have been addressed in numerous investigations, there still remain a lot of open questions for the case of systems with distributed parameters, especially when the delay effects are incorporated. Here, we consider a general non-homogeneous one-dimensional heat equation with delay in both higher and lower order terms subject to non-homogeneous initial and boundary conditions. For this, we prove the unique existence of a classical solution as well as its continuous dependence on the data.

description: This paper presents recent development of tunable microwave liquid crystal (LC) components in the lower millimeter wave (mmW) regime up to the W-band. With the utilization of increasing frequency, conventional metallic waveguide structures prove to be impractical for LC-based components. In particular, the integration of the electric bias network is extremely challenging. Therefore, dielectric waveguides are a promising alternative to conventional waveguides, since electrodes can be easily integrated in the open structure of dielectric waveguides. The numerous subcategories of dielectric waveguides offer a high degree of freedom in designing smart millimeter wave components such as tunable phase shifters, filters and steerable antennas. Recent research resulted in many different realizations, which are analyzed in this paper. The first demonstrators of phased array antennas with integrated LC-based phase shifters are reviewed and compared. In addition, beam steering with a single antenna type is shown. Furthermore, the possibility to realize tunable filters using LC-filled dielectric waveguides is demonstrated.

description: We present a simple, experimentally realizable method to make coherent three-body interactions dominate the physics of an ultracold lattice gas. Our scheme employs either lattice modulation or laser-induced tunneling to reduce or turn off two-body interactions in a rotating frame, promoting three-body interactions arising from multi-orbital physics to leading-order processes. This approach provides a route to strongly-correlated phases of lattice gases that are beyond the reach of previously proposed dissipative three-body interactions. In particular, we study the mean-field phase diagram for spinless bosons with three- and two- body interactions, and provide a roadmap to dimer states of varying character in 1D. This new toolset should be immediately applicable in state-of-the-art cold atom experiments.

Moreover, we give an explicit representation of the control function steering the system into a given final state. Under certain decay properties for corresponding Fourier coefficients which can be interpreted as a sufficiently high Sobolev regularity of the data, both control function and the solution are proved to be regular in the classical sense both with respect to time and space variables.

Utility of the Weak Temperature Gradient Approximation for Earth-Like Tidally Locked Exoplanets

Year: 2013
Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)
subject: FOS: Physical sciences

description: Planets in M dwarf stars' habitable zones are likely to be tidally locked with orbital periods of order tens of days. This means that the effects of rotation on atmospheric dynamics will be relatively weak, which requires small horizontal temperature gradients above the boundary layer of terrestrial atmospheres. An analytically solvable and dynamically consistent model for planetary climate with only three free parameters can be constructed by making the weak temperature gradient (WTG) approximation, which assumes temperatures are horizontally uniform aloft. The extreme numerical efficiency of a WTG model compared to a 3D general circulation model (GCM) makes it an optimal tool for Monte Carlo fits to observables over parameter space. Additionally, such low-order models are critical for developing physical intuition and coupling atmospheric dynamics to models of other components of planetary climate. The objective of this paper is to determine whether a WTG model provides an adequate approximation of the effect of atmospheric dynamics on quantities likely to be observed over the next decade. To do this we first tune a WTG model to GCM output for an Earth-like tidally locked planet with a dry, 1 bar atmosphere, then generate and compare the expected phase curves of both models. We find that differences between the two models would be extremely difficult to detect from phase curves using JWST. This result demonstrates the usefulness of the WTG approximation when used in conjunction with GCMs as part of a modeling hierarchy to understand the climate of remote planets.

description: Network ecologists investigate the structure, function, and evolution of ecological systems using network models and analyses. For example, network techniques have been used to study community interactions (i.e., food-webs, mutualisms), gene flow across landscapes, and the sociality of individuals in populations. The work presented here uses a bibliographic and network approach to (1) document the rise of Network Ecology, (2) identify the diversity of topics addressed in the field, and (3) map the structure of scientific collaboration among contributing scientists. Our aim is to provide a broad overview of this emergent field that highlights its diversity and to provide a foundation for future advances. To do this, we searched the ISI Web of Science database for ecology publications between 1900 and 2012 using the search terms for research areas of Environmental Sciences & Ecology and Evolutionary Biology and the topic tag ecology. From these records we identified the Network Ecology publications using the topic terms network, graph theory, and web while controlling for the usage of misleading phrases. The resulting corpus entailed 29,513 publications between 1936 and 2012. We document the rapid rise in Network Ecology publications per year reaching a magnitude of over 5% of the ecological publications in 2012. Drawing topical information from the publication record content (titles, abstracts, keywords) and collaboration information from author listing, our analysis highlights the diversity and clustering of topics addressed within Network Ecology and reveals the highly collaborative approach of scientists publishing in this field. We conclude that Network Ecology is a large and rapidly growing area of ecology, and we expect continued growth of this research field.

Diabetes mellitus is among the four major non-communicable diseases warranting immediate attention. It associated with long term potential effect on almost all systems of body & leads to various complications. Diabetes is a multifactorial disease with both genetic & environmental influences as aetiology. Environmental factors like changing life style, urban migration, obesity has major role in diabetes manifestation. Its prevalence is continuously increasing especially in low and middle-income countries. Considering the Global Diabetes Compact, a new global initiative with a specific focus on assisting low and middle-income countries, was introduced by WHO in April 2021. Its goal is to achieve sustainable diabetes prevention and care. Ayurveda a Traditional system of Medicine primarily focuses on prevention of disease. Proper knowledge of etiological factors & various risk factors helps in both treatment as well as prevention of the disease. Objective: To assess predominant risk factors for Diabetes Mellitus (Madhumeha). Methodology: This is a descriptive cross-sectional study conducted at MGACH & RC, Salod (H), Wardha district. Total 100 diagnosed patients of type 2 diabetes selected by convenient sampling method were enrolled in the study. Patients were contacted & interviewed at medicine OPD of MGACH & RC, Salod (H) Wardha once a week with semi-structured questionnaire and data will be collected as per questionnaire. Conclusion: The present study generates reliable data regarding potential risk factors of type 2 diabetes in rural part of wardha district.

description: Literature analysing the interrelation of religion and economic performance suggests religion to explain differences in household income. Religious communities foster economically conducive attitudes and are important sources of social capital, particularly under weak economic structures. This paper targets at investigating effects of religiosity on rural household income using survey data from Greater Sekhukhune in the Limpopo Province of South Africa. Using insights from religious studies within a conceptual framework of rural household decision-making, the authors estimate an income equation that includes measures for religious affiliation. While church membership per se does not reveal a significant effect on household income, the results show a positive and robust relationship for membership in the Zion Christian Church and the practice of African traditional religion.
High Availability for Carrier-Grade SIP Infrastructure on Cloud Platforms

Subjects: Computer science

description: SIP infrastructure on cloud platforms has the potential to be both scalable and highly available. In our previous project, we focused on the scalability aspect of SIP services on cloud platforms; the focus of this project is on the high availability aspect. We investigated the effects of component fault on service availability with the goal of understanding how high availability can be guaranteed even in the face of component faults. The experiments were conducted empirically on a real system that runs on Amazon EC2. Our analysis shows that most component faults are masked with a simple automatic failover technique. However, we have also identified fundamental problems that cannot be addressed by simple failover techniques; a problem involving DNS cache in resolvers and a problem involving static failover configurations. Recommendations on how to solve these problems are included in the report.

The association between physical activity and colorectal adenoma is equivocal. This study was designed to assess the relationship between physical activity and colorectal adenoma recurrence.
Methods
Pooled analyses from two randomized, controlled trials included 1,730 participants who completed the Arizona Activity Frequency Questionnaire at baseline, had a colorectal adenoma removed within 6 months of study registration, and had a follow-up colonoscopy during the trial. Logistic regression modeling was employed to estimate the effect of sedentary behavior, light-intensity physical activity, and moderate-vigorous physical activity on colorectal adenoma recurrence.
Results
No statistically significant trends were found for any activity type and odds of colorectal adenoma recurrence in the pooled population. However, males with the highest levels of sedentary time experienced 47 % higher odds of adenoma recurrence. Compared to the lowest quartile of sedentary time, the ORs (95 % CIs) for the second, third, and fourth quartiles among men were 1.23 (0.88, 1.74), 1.41 (0.99, 2.01), and 1.47 (1.03, 2.11), respectively (p trend = 0.03). No similar association was observed for women.
Conclusions
This study suggests that sedentary behavior is associated with a higher risk of colorectal adenoma recurrence among men, providing evidence of detrimental effects of a sedentary lifestyle early in the carcinogenesis pathway.

description: We present PANDA, an open-source tool that has
been purpose-built to support whole system reverse engineering.
It is built upon the QEMU whole system emulator, and so analyses
have access to all code executing in the guest and all data.
PANDA adds the ability to record and replay executions, enabling
iterative, deep, whole system analyses. Further, the replay log files
are compact and shareable, allowing for repeatable experiments.
A nine billion instruction boot of FreeBSD, e.g., is represented
by only a few hundred MB. Further, PANDA leverages QEMU's
support of thirteen different CPU architectures to make analyses
of those diverse instruction sets possible within the LLVM IR. In
this way, PANDA can have a single dynamic taint analysis, for
example, that precisely supports many CPUs. PANDA analyses
are written in a simple plugin architecture which includes a
mechanism to share functionality between plugins, increasing
analysis code re-use and simplifying complex analysis development.
We demonstrate PANDA's effectiveness via a number of
use cases, including enabling an old but legitimate version of
Starcraft to run despite a lost CD key, in-depth diagnosis of an
Internet Explorer crash, and uncovering the censorship activities
and mechanisms of a Chinese IM client.

description: Reasoning and talking about time is to a great extent reasoning and talking about what actually happens or might happen at some time or another. This is perhaps not crucial if our concern is with abstract temporal reasoners or planners intended for specific applications, but it arguably matters for the prospects of knowledge representation and natural language semantics. The variety of the world is the variety of the things that happen, and we can’t deal with it without taking events at face value (just as we cannot deal with physical bodies or masses by confining ourselves to their spatial coordinates).  The purpose of this paper is to expand on this by further investigating the subtle connections between time and events. After a brief review, in the first part we shall generalize the notion of an event structure to that of a refinement structure, where various degrees of temporal granularity are accommodated. In the second part we shall then investigate how these structures can account for the context-dependence of temporal structures in natural language semantics.
The Filth and the Fury: An Essay on Punk Rock Heavy Metal Karaoke

Subjects: Music

description: Musical voices cross and enunciate thresholds. Along these lines, I have attempted to map some of the thresholds that are crossed and enunciated by singers and other participants at PMK. These thresholds are diverse, with boundaries negotiated between and around musical genres, gender roles, ontological notions of subjectivity, and shifting geographic significances in New York City. To examine these boundary negotiations, I chose abjection as an interpretive frame for a number of reasons. First, the event is grounded in two performative lexicons- the genre of punk and the practice of karaoke- that are already discursively situated in terms of the abject. Also, given that abjection, as theorized by Kristeva, is centrally concerned with the body, and especially with horrific and sexualized experiences with the body, it provides a useful lens for analyzing the vocal and bodily display, and the bawdy humor and horrific imagery, found in abundance at PMK. Finally, and most importantly, the regular participants utilize the terms of the abject in their own speech and in their own interpretations of the event.
Musical Meaning for the Few: Instances of Private Reception in the Music of Brahms

Subjects: Music

description: The received view of Brahms as a champion of "absolute" music has dominated the scholarly reception of his compositional output for over a century, and with good reason. Except in a few early works, Brahms rarely published his instrumental music with any of the suggestive clues that his contemporaries used in their program music, while his preference for the apparently more classical genres, forms, and procedures seems to distance him from the overtly progressive tendencies of Romanticism that eschewed reliance on classical conventions. What transpired in purely musical terms also was evident in the written word, both that of Brahms and of others. In what follows, I steer a middle ground by arguing that Brahms's music has a double reception history: within his circle of intimates, Brahms often transmitted suggestive, even programmatic, clues but in the public sphere, he refrained from stipulating any such clues whatsoever, thereby distancing the same music from the more openly specified extramusical associations that characterized program music in the latter half of the nineteenth century. What emerges in this compromise is a hitherto unacknowledged species of music that exists simultaneously in two contrary ways: as program music for those to whom Brahms stipulated suggestive titles, poetic mottoes, or actual literary texts; as "abstract" or "absolute" music for everyone else.

description: This study evaluates the postsecondary and labor market outcomes of students who attended for-profit colleges. The evaluation complements a similar study by Deming, Goldin, and Katz (2012) that found significant differences in outcomes between students in for-profit colleges and those in other sectors. In this study, the authors use the Education Longitudinal Study of 2002, a nationally representative survey monitoring the transitions of young people who were 10th graders in 2002, and compare outcomes during the college years and up to age 26.
In accord with Deming et al., the authors find adverse levels of borrowing and some evidence of wage penalties for students who attended a for-profit college. Paradoxically, however, these results are not associated with lower attainment levels, and there is little evidence that for-profit students were less satisfied with their college experience. These results hold even with detailed controls for ability, for alternative comparison groups, for selection into the for-profit sector, and for alternative designations of for-profit college enrollment. However, the combined effect of higher borrowing and lower earnings for students at for-profit colleges is substantial, such that the average returns to community college dominate those at for-profit colleges.
A Note on the Transitivity of Parthood

description: That parthood is a transitive relation is among the most basic principles of classical mereology. Alas, it is also very controversial. In a recent paper, Ingvar Johansson has put forward a novel diagnosis of the problem, along with a corresponding solution. The diagnosis is on the right track, I argue, but the solution is misleading. And once the pieces are properly put together, we end up with a reinforcement of the standard defense of transitivity on behalf of classical mereology.

description: Reliable condition monitoring (CM) can be an effective means to significantly reduce wind turbine (WT) downtime, operations and maintenance costs and plan preventative maintenance in advance. The WT generator voltage and current output, if sampled at a sufficiently high rate (kHz range), can provide a rich source of data for CM. However, the electrical output of the WT generator is frequently shown to be complex and noisy in nature due to the varying and turbulent nature of the wind. Thus, a fully satisfactory technique that is capable to provide accurate interpretation of the WT electrical output has not been achieved to date. The objective of the research described in this thesis is to develop reliable WT CM using advanced signal processing techniques so that fast analysis of non-stationary current measurements with high diagnostic accuracy is achieved. The diagnostic accuracy and reliability of the proposed techniques have been evaluated using data from a laboratory test rig where experiments are performed under two levels of rotor electrical asymmetry faults. The experimental test rig was run under fixed and variable speed driving conditions to investigate the kind of results expected under such conditions. An effective extended Kalman filter (EKF) based method is proposed to iteratively track the characteristic fault frequencies in WT CM signals as the WT speed varies. The EKF performance was compared with some of the leading WT CM techniques to establish its pros and cons. The reported experimental findings demonstrate clear and significant gains in both the computational efficiency and the diagnostic accuracy using the proposed technique. In addition, a novel frequency tracking technique is proposed in this thesis to analyse the non-stationary current signals by improving the capability of a continuous wavelet transform (CWT). Simulations and experiments have been performed to verify the proposed method for detecting early abnormalities in WT generators. The improved CWT is finally applied for developing a new real-time CM technique dedicated to detect early abnormalities in a commercial WT. The results presented highlight the advantages of the improved CWT over the conventional CWT to identify frequency components of interest and cope with the non-linear and non-stationary fault features in the current signal, and go on to indicate its potential and suitability for WT CM.

description: Il primo genaio del 1892 Ellis Island divenne ufficialmente stazione federale per l'imigrazione, solo un anno dopo che il governo federale si era il totale controllo e la piena autorità sulla gestinoe degli immigrati negli Stati Uniti. Il dato probabilmente più eclantante è che tra il 1892 e il 1954 (anno della sua chiusura) Ellis Island processò circa dodici milioni di immigrati. Altrettanto impressionante il numbero di visitatori che, in media, hanno visitato il museao da quando esso fu inaugurato nel 1990: circa dodicimila visitatori al giorno, più o meno quante persone venivano esasminate in quello stesso luogo, nei primi anni del novecento, daoi funzionari per l'immigrazione.
