Ginzburg-Landau Polynomials and the Asymptotic Behavior of the Magnetization Near Critical and Tricritical Points

description: For the mean-field version of an important lattice-spin model due to Blume and Capel, we prove unexpected connections among the asymptotic behavior of the magnetization, the structure of the phase transitions, and a class of polynomials that we call the Ginzburg-Landau polynomials. The model depends on the parameters n, beta, and K, which represent, respectively, the number of spins, the inverse temperature, and the interaction strength. Our main focus is on the asymptotic behavior of the magnetization m(beta_n,K_n) for appropriate sequences (beta_n,K_n) that converge to a second-order point or to the tricritical point of the model and that lie inside various subsets of the phase-coexistence region. The main result states that as (beta_n,K_n) converges to one of these points (beta,K), m(beta_n,K_n) ~ c |beta - beta_n|^gamma --> 0. In this formula gamma is a positive constant, and c is the unique positive, global minimum point of a certain polynomial g that we call the Ginzburg-Landau polynomial. This polynomial arises as a limit of appropriately scaled free-energy functionals, the global minimum points of which define the phase-transition structure of the model. For each sequence (beta_n,K_n) under study, the structure of the global minimum points of the associated Ginzburg-Landau polynomial mirrors the structure of the global minimum points of the free-energy functional in the region through which (beta_n,K_n) passes and thus reflects the phase-transition structure of the model in that region. The properties of the Ginzburg-Landau polynomials make rigorous the predictions of the Ginzburg-Landau phenomenology of critical phenomena, and the asymptotic formula for m(beta_n,K_n) makes rigorous the heuristic scaling theory of the tricritical point.

description: We introduce a new framework for constructing tests of general semiparametric hypotheses which have nontrivial power on the $n^{-1/2}$ scale in every direction, and can be tailored to put substantial power on alternatives of importance. The approach is based on combining test statistics based on stochastic processes of score statistics with bootstrap critical values.

Women's perceptions of factors that enhance and inhibit adaptation to chronic hemodialysis when renal transplantation is not an option
Creators: name: Maxwell, Lynne
Publisher: name: University of British Columbia
Year: 2010

description: Factors Influencing Women's Adaptation to Hemodialysis When Renal Transplantation is not an Option The intent of this study was to explore and describe factors that influence adaptation from the perspective of women on hemodialysis for whom renal transplantation is not an option. Phenomenology was the research design selected for this study in order to understand the experience of these women clients. Data were collected during audio-taped interviews of eight women and were analyzed concurrently with data collection to identify common themes. Two central themes emerged: the adaptation process and the theme of connectedness. The adaptation process was described as a six-phase process. Connectedness was defined as being connected to others and/or sources of life's energy. Several key factors that either facilitated or interfered with adaptation were identified for each of these two themes. Key factors that facilitated adaptation throughout the adaptation process Included a first run on dialysis, experience with adversity, emotional and instrumental support, coping behaviors such as asserting control and reframing the situation, diversions, adequate rest and confidence in health-care professionals. Factors interfering with adaptation to hemodialysis throughout the adaptation process included the gradual and ambiguous nature of renal disease, increasing dependence, reduced energy, transportation to dialysis, compromised somatic health, difficulty with assertiveness, prolonged stressors and lack of confidence in health-care professionals. Specific factors that influenced connectedness were identified. The facilitating factors identified were satisfactory relationships, nurturing others, normalizing, a harmonious atmosphere on the hemodialysis unit and pleasurable activities. Key factors interfering with adaptation related to the connectedness theme were isolation from others, unsympathetic others, ineffective communication with health-care professionals, and exclusion from activities. The findings relative to the adaptation process were discussed in the light of the literature on adapting to illness and stress. Connectedness was discussed primarily in relation to the literature exploring the socialization of women. Implications for nursing practice, education and research arising from these findings were outlined.

description: Linear irreversible thermodynamics asserts that the instantaneous local spontaneous entropy production is always nonnegative. However for a viscoelastic fluid this is not always the case. Given the fundamental status of the Second Law, this presents a problem. We provide a new derivation of the Second Law, from first principles, which is valid for the appropriately time averaged entropy production allowing the instantaneous entropy production to be negative for short intervals of time. We show that time averages (rather than instantaneous values) of the entropy production are nonnegative. We illustrate this using molecular dynamics simulations of oscillatory shear.

description: In dieser Arbeit werden zwei Antriebsstrangprüfstände zur Ableitung von Konstruktionszielgrößen für Antriebssysteme handgehaltener Power-Tools entwickelt, verifiziert und beispielhafte Zielgrößen für die Konstruktion ermittelt. Durch physische Komponententests unter Einbindung in die Umgebungssysteme wird es möglich, Antriebskomponenten früh im Produktentwicklungsprozess zu untersuchen und aufeinander abzustimmen. Besondere Vorteile bietet dies in frühen Produktentwicklungsphasen, in denen noch nicht alle Komponenten der Maschine funktionsfähig vorliegen. Damit wird das Frontloading in der Produktentwicklung unterstützt und gefördert.

Die Arbeit beschreibt das Vorgehen zur Entwicklung zweier Antriebsstrangprüfstände für handgehaltene Power-Tools. Zunächst werden in manuellen Tests mit Hilfe von mit Messtechnik ausgestatteten Maschinen belastungsabhängige Systemgrößen experimentell erfasst und Erkenntnisse zum Systemverhalten in der Anwendung gewonnen. Es erfolgt die Entwicklung eines Prüfstands für Dynamikuntersuchungen an einem Winkelschleiferantriebsstrang und eines Prüfstands für die Untersuchung des Auslöseverhaltens von Überrastkupplungen in Akkubohrschraubern. Für beide Antriebsstrangprüfstände werden Lastmodelle aus den manuellen Tests generiert. Anhand der Anforderungen an die Antriebsstrangprüfstände werden diese verifiziert.

Die Ableitung von Konstruktionszielgrößen wird in Experimenten an den Antriebsstrangprüfständen durch beispielhafte Anwendungen gezeigt. Für den Lagersitz eines Winkelschleiferantriebs werden Bauteilvarianten, welche sich in ihrem Elastizitätswert unterscheiden, hinsichtlich dem Schwingungsverhalten des Triebstrangs untersucht und Konstruktionszielgrößen daraus abgeleitet. Für die Überrastkupplung eines Akkubohrschraubers werden Geometrievarianten hinsichtlich deren Einfluss auf das dynamische Verhalten des Triebstrangs untersucht und aus den Erkenntnissen Konstruktionszielgrößen abgeleitet.

description: The photo-luminescence features of Ge-oxygen defect centers in a 100nm thick Ge-doped silica film on a pure silica substrate were investigated by looking at the emission spectra and time decay detected under synchrotron radiation excitation in the 10-300 K temperature range. This center exhibits two luminescence bands centered at 4.3eV and 3.2eV associated with its de-excitation from singlet (S1) and triplet (T1) states, respectively, that are linked by an intersystem crossing process. The comparison with results obtained from a bulk Ge-doped silica sample evidences that the efficiency of the intersystem crossing rate depends on the properties of the matrix embedding the Ge-oxygen defect centers, being more effective in the film than in the bulk counterpart.

The Structural Cause of Gravity: A Foundational Science Perspective
Creators: name: Ruff, James
Publisher: name: Zenodo
Year: 2025

description: > This paper presents a structural model for gravity grounded in Foundational Science, reframing gravitational phenomena as a consequence of temporal current interacting with domain-specific pressure. By reinterpreting gravity not as an attractive force or a geometric distortion, but as a function of current modulation through resistance, we offer a coherent and causally complete explanation for observed gravitational effects. This model eliminates the need for dark matter and general relativity's spacetime curvature, replacing them with domain-consistent constructs: temporal current, temporal tide, and temporal pressure.

description: The Landau-Pollak uncertainty relation treats a pair of rank one projection valued measures and imposes a restriction on their probability distributions. It gives a nontrivial bound for summation of their maximum values. We give a generalization of this bound (weak version of the Landau-Pollak uncertainty relation). Our generalization covers a pair of positive operator valued measures. A nontrivial but slightly weak inequality that can treat an arbitrary number of positive operator valued measures is also presented.

description: We analyze static properties of nucleons in the two flavor holographic QCD model of Sakai and Sugimoto described effectively by a five-dimensional U(2) Yang-Mills theory with the Chern-Simons term on a curved background. The baryons are represented in this model as a soliton, which at a time slice is approximately the BPST instanton with a fixed size. First, we construct a chiral current in four dimensions from the Noether current of local gauge transformations which are non-vanishing on the boundaries of the extra dimension. We examine this chiral current for nucleons with quantized collective coordinates to compute their charge distribution, charge radii, magnetic moments and axial vector coupling. Most of the results are better close to the experimental values than in the Skyrme model. We discuss the problems of our chiral current; non-uniqueness of the local gauge transformation for defining the current, and its gauge-noninvariance.

Cross-cultural study of test-wiseness

Publisher: name: University of British Columbia

description: The objectives of this study were to investigate the cultural differences in test-wiseness between Chinese and Canadian students; to study the impact of test-wiseness on British Columbia Grade 12 provincial examination results among Chinese students in British Columbia; and to examine the relationship of test-wiseness, and four correlates (verbal ability, achievement motivation, length of residency in Canada, multiple choice experience) among the Chinese students. The Test of Test-wiseness and Student Survey questionnaire were administered to 41 Grade 12 foreign Chinese students who wrote the provincial examinations in January 1990. Completed test data were compared with the same data from Canadian and Chinese immigrant students who wrote the provincial examination in June 1989. The data were analyzed by a linear regression model. The results indicated that ethnicity accounted for a significant amount of variance in test-wiseness. Foreign Chinese students were significantly less test-wise than both Canadian and Chinese immigrant students. Foreign Chinese students scored significantly lower than the other two groups in absurd-options, different-options, stem-options link and guessing subtests in the Test of Test-wiseness. The results also showed that test-wiseness did not account for a significant amount of variance in provincial examination scores (English 12 and Algebra 12). The four correlates together accounted for very little variance in test-wiseness. None of them significantly correlated with test-wiseness, except that length of residency in Canada correlated positively with test-wiseness. Finally, the three ethnic groups showed no significant differences in achievement motivation but foreign Chinese students scored significantly lower than Chinese immigrant students who scored in turn lower than Canadian students in verbal ability. The findings imply that language plays a crucial part in test-taking situations. With inadequate English language skills, foreign Chinese students were unable to satisfactorily comprehend the test questions, and hence their test performance were very close to what would be expected from random guessing. It is suggested that these students require examination coaching skills as well as improvement in English language skills.

description: The prompt optical emission contemporaneous with the $γ$-rays from $γ$-ray bursts (GRBs) carries important information on the central engine and explosion mechanism. We study the time lag between prompt optical emission and $γ$-rays in GRB 990123 and GRB 041219a, which are the only two GRBs had been detected at optical wavelengths during the ascending burst phase. Assuming profiles of prompt optical light curves are the same as the prompt $γ$-rays, we simulate optical light curves with different time lags and compare them with the observed optical flux. Then the best fit time lag and its error are determined by chi-squared values. We find that time lags between prompt optical emission and $γ$-rays in GRB host galaxy rest-frames are consistent in the two GRBs, which is $5\sim7$ s for GRB 990123 and $1\sim5$ s for GRB 041219a. This result is consistent with a common origin of prompt optical and $γ$-ray emissions in the two GRBs. Based on synchrotron cooling model, we also derive the parameters for the two GRBs.

description: The Ginzburg-Landau Hamiltonian for incommensurate frustrated classical spin systems is analyzed. The coupling to phonons through the Dzyaloshinskii-Moriya interaction and/or the four-spin exchange interaction of the Coulomb origin under the egde-sharing network of magnetic and ligand ions drive chiral spin piarings, introducing two successive second-order phase transitions upon cooling. First, a vector spin-chiral order appears with an either parity, leaving an O(2) chiral spin liquid. Then, the O(2) symmetry is broken by the spin ordering into a helical magnetic state. Possible candidate materials are also discussed.

We construct Kahler potential of their effective action. In the large size limit Kahler metric is well approximated by kinetic energy of walls and junctions, which is understood in terms of tropical geometry. Kahler potential can be expressed in terms of hypergeometric functions which are useful to understand small size behavior. Even when the loop shrinks, the metric is regular with positive curvature. Moduli space of a single triangle loop has a geometry between a cone and a cigar.

Electron spin resonance measurements performed ex situ a few hours after the end of exposure permit to complete the information acquired by optical absorption by detection of the paramagnetic Ge(1) and Ge-E' centers laser-induced in the samples.

description: We consider decays of four intersecting fluxbranes which are obtained by considering a higher dimensional Kerr blackhole with four angular momentum parameters, which is the maximum number of angular momentum parameters in string/M-theory. As a result of the intersection, we get lower dimensional fluxbranes. Since generic magnetic fields break all supersymmetries, the resulting fluxbranes are unstable and will decay. Just as a single fluxbrane decays into the nucleation of spherical D6-branes; the intersecting ones decay into the nucleation of lower dimensional spherical branes. Contrary to a single fluxbrane case, the decay of four intersecting fluxbranes has additional decay channels. We also calculate the corresponding Euclidean action to obtain the decay rates. Although the action cannot be explicitly and simply written in terms of the magnetic parameters, we can extract some interesting results by taking various limits of the magnetic parameters.

description: We determine the existence of critical lines in dimerized quantum spin ladders in their phase diagram of coupling constants using the finite-size DMRG algorithm. We consider both staggered and columnar dimerization patterns, and antiferromagnetic and ferromagnetic inter-leg couplings. The existence of critical phases depends on the precise combination of these patterns. The nature of the massive phases separating the critical lines are characterized with generalized string order parameters that determine their valence bond solid (VBS) content.

description: An energy for the homogeneous cosmological models is presented. More specifically, using an appropriate natural prescription, we find the energy within any region with any gravitational source for a large class of gravity theories--namely those with a tetrad description--for all 9 Bianchi types. Our energy is given by the value of the Hamiltonian with homogeneous boundary conditions; this value vanishes for all regions in all Bianchi class A models, and it does not vanish for any class B model. This is so not only for Einstein's general relativity but, moreover, for the whole 3-parameter class of tetrad-teleparallel theories. For the physically favored one parameter subclass, which includes the teleparallel equivalent of Einstein's theory as an important special case, the energy for all class B models is, contrary to expectation, negative.

Needs of family members of critically ill brain-injured patients during the ICU experience
Creators: name: FitzGerald, Patricia Anne
Publisher: name: University of British Columbia
Year: 2010

description: This descriptive exploratory study was designed to determine the perceived importance of selected needs of family members of critically ill brain-injured patients. In addition, the personal/demographic factors which may have influenced the needs of these family members were investigated, as well as the reasons family members perceived these needs as important or unimportant. A convenience sample of one family member for each of 15 critically ill brain-injured patients was selected from two tertiary care hospitals and the community. Family members were interviewed using a pre-determined interview guide and asked to verbally rate 20 need statements on a four-point Likert-type scale. Generally, family members perceived all 20 needs to be important. However, the importance of each need was influenced by the family members' personal/demographic factors. No significant statistical relationship was found between personal/demographic factors and the family members' perceptions of the importance of selected needs. However, the findings of the study suggest that family members relate their needs to their present experience, and thus individual assessment of family members' needs is crucial.

description: Bei der Analyse von höherdimensionalen Daten kann deren Gestalt wichtige Informationen über den Datensatz liefern. Bei einer gegebenen Punktwolke, die aus einem unbekannten topologischen Raum ausgewählt wurde, versucht die Topologische Datenanalyse (TDA) den ursprünglichen Raum zu rekonstruieren. Dieser Beitrag soll eine Einführung in die Topologische Datenanalyse geben und konzentriert sich dabei auf zwei wichtige Aspekte: die Persistente Homologie und den Mapper. Dabei werden zuerst die notwendigen theoretischen Grundlagen vorgestellt und anschließend wird die Methodik bei der Visualisierung von Daten eingesetzt.
Die Persistente Homologie ist eines der Standardwerkzeuge in der TDA. Sie findet ihre Anwendung beispielsweise in den Bereichen Formerkennung und -beschreibung. Der Mapper als zweites wichtiges Konzept der TDA wandelt umfangreiche, höherdimensionale Datensätze in Simplizialkomplexe um und kann dadurch geometrische und topologische Eigenschaften der Daten bestimmen. Des Weiteren ist die Mapper-Methode ein brauchbares Werkzeug zur Visualisierungen von mehrdimensionalen Daten, woran statistische Verfahren scheitern.
description: In the analysis of higher-dimensional data their shape can provide important information about the dataset. Given a point cloud sampled from an unknown topological space, topological data analysis tries to reconstruct the original space. This paper provides an introduction into topological data analysis (TDA) and focuses on two important aspects: Persistent Homology and Mapper. First, the theoretical basics are introduced and then the methodology is applied to visualize data.
Persistent Homology represents a standard tools in the TDA. This approach is used, for example, in shape recognition and description. The Mapper is a second important concept of the TDA and converts wide, higher-dimensional datasets into simplicial complexes. By that it can determine geometric and topological properties of the data. Furthermore, the Mapper method is a useful tool for the visualization of multi-dimensional data, where statistical methods fail.

Creators: name: Addo, Akosua Obuo
Publisher: name: University of British Columbia
Year: 2010

description: Changes occurring in the educational system of Ghana since independence in 1957 have been many and varied. The recent inclusion of the Cultural Studies program as part of the compulsory core curriculum is an example of such a change. The Cultural Studies program was designed to nurture cultural awareness and appreciation in the Ghanaian school child through music, drama, religion and social systems. The focus of this study was Music in the Cultural Studies program. The approach of the music teacher to music teaching and learning determines the successful realization of the curriculum. Music teaching strategies employed in Ghanaian elementary schools are many and varied. The content of the curriculum the teacher has to work with also enhances the realization of the program objectives. The purpose of this study was to identify and describe music teaching strategies and their degree of use in Ghanaian elementary schools and also offer suggestions for improving music instruction drawing on Ghanaian indigenous methods of music education, the Orff-Schulwerk, and Kodály pedagogy. In a survey involving fifty-six music teachers from five of the ten regions of Ghana, the researcher drew the following conclusions: a) the most frequently used teaching strategies included singing games, vocables, solfege, speech and poetry, movement and dance. b) there was evidence to suggest that the music teaching strategies of teachers are not related to their regional location, district, gender, teaching experience, or academic qualifications. c) It is feasible to combine the approaches of the Kodály pedagogy, the Orff-Schulwerk, and Ghanaian indigenous forms of music education in the development of a curriculum framework aimed at improving music instructional methodology in Ghanaian elementary schools.

E-business curriculum

description: This script is part of the process of defining the curriculum of a e-business master course that opened in 2018 in the Business School of the Polytechnic of Porto (ISCAP), Portugal.

With the aim of designing a course that corresponded as much as possible to the needs of the labour market and incorporating the expectations and concerns of potential employers and future students, the authors carried out 1) an inquiry, doing interviews to potential employers, and 2) a survey, applying a questionnaire to ISCAP final year students of some after working hours degrees, and to graduate students who are already in the labour market.

description: Parameters from the literature, such as positions, photoelectric absorption (nH), spin and orbital periods, and distances or redshifts, were collected for all ~500 sources detected by INTEGRAL-ISGRI so far. We investigate where new and previously-known sources detected by ISGRI fit in the parameter space of high-energy objects, and we use the parameters to test correlations expected from theoretical predictions. For example, the influence of the local absorbing matter on periodic modulations is studied for Galactic High-Mass X-ray Binaries (HMXBs) with OB supergiant and Be companions. We examine the spatial distribution of different types of sources in the Milky Way using various projections of the Galactic plane, in order to highlight signatures of stellar evolution and to speculate on the origin of the group of sources whose classifications are still uncertain. ISGRI has detected similar numbers of X-ray Binaries and Active Galactic Nuclei (AGN). The former group contains new members of the class of HMXBs with supergiant stellar companions. Thanks to these additional systems, we are able to show that HMXBs are generally segregated in plots of intrinsic nH versus the orbital period of the system and versus the spin period of the pulsar, based on whether the companion is a Be or an OB supergiant star. We also find a tentative but expected anti-correlation between nH and the orbital period, and a possible and unexpected correlation between the nH and the spin period. While only a handful of new Low-Mass X-ray Binaries (LMXBs) have been discovered, there are many sources that remain unclassified and they appear to follow a spatial distribution typical of Galactic sources (especially LMXBs) rather than extragalactic sources.

description: Understanding maternal immune tolerance is crucial for the development of therapeutics for immunological pregnancy complications. Decidual regulatory T cells (Tregs) play a pivotal role in the maintenance of maternal immune tolerance. Using a murine allogeneic pregnancy model in the current study, we identified the up-regulation of gonadotropin-releasing hormone receptor (GnRHR) in decidual T cell subsets including CD4+ conventional T cells, CD8+ T cells, and CD4+Foxp3+ Tregs. Using a lentivirus-mediated GnRHR overexpression system and a GnRHR agonist, we found that GnRHR activation decreased the expression of Treg functional molecules such as IL10 (IL-10), IL-35 subunit EBI3 (Ebi3), IL2RA (CD25), TNFRSF18 (GITR), ICOS, and Treg master regulator FOXP3. The functional analysis indicated that GnRHR activation impairs the ability of Tregs to inhibit conventional T cell proliferation. We also revealed that GnRHR activation suppressed the mechanistic target of rapamycin (mTOR) signaling in GnRHR-overexpressing splenic Tregs (Wild type C57BL/6 J background) and decidual Tregs. MHY1485, a potent mTOR activator, effectively abolished the effect of the GnRHR agonist and promoted the immunosuppressive capability of Tregs. Furthermore, in an adoptive transfer model, Treg-specific GnRHR knockdown increased Foxp3 expression in decidual Tregs while decreasing the production of IFN-γ and IL-17 in decidual effector CD4+ T cells and reducing the production of IFN-γ in decidual effector CD8+ T cells. Taken together, the present study unveils a novel mechanism by which the immunosuppressive function of decidual Tregs is modulated, and deepens our understanding of maternal immune tolerance.
Spherically Symmetric Gravitational Collapse of General Fluids

description: We express Einstein's field equations for a spherically symmetric ball of general fluid such that they are conducive to an initial value problem. We show how the equations reduce to the Vaidya spacetime in a non-null coordinate frame, simply by designating specific equations of state. Furthermore, this reduces to the Schwarzschild spacetime when all matter variables vanish. We then describe the formulation of an initial value problem, whereby a general fluid ball with vacuum exterior is established on an initial spacelike slice. As the system evolves, the fluid ball collapses and emanates null radiation such that a region of Vaidya spacetime develops. Therefore, on any subsequent spacelike slice there exists three regions; general fluid, Vaidya and Schwarzschild, all expressed in a single coordinate patch with two free-boundaries determined by the equations. This implies complicated matching schemes are not required at the interfaces between the regions, instead, one simply requires the matter variables tend to the appropriate equations of state. We also show the reduction of the system of equations to the static cases, and show staticity necessarily implies zero ``heat flux''. Furthermore, the static equations include a generalization of the Tolman-Oppenheimer-Volkoff equations for hydrostatic equilibrium to include anisotropic stresses in general coordinates.

description: We investigate propagating fronts in disordered media that belong to the universality class of wetting contact lines and planar tensile crack fronts. We derive from first principles their nonlinear equations of motion, using the generalized Griffith criterion for crack fronts and three standard mobility laws for contact lines. Then we study their roughness using the self-consistent expansion. When neglecting the irreversibility of fracture and wetting processes, we find a possible dynamic rough phase with a roughness exponent of $ζ=1/2$ and a dynamic exponent of z=2. When including the irreversibility, we conclude that the front propagation can become history dependent, and thus we consider the value $ζ=1/2$ as a lower bound for the roughness exponent. Interestingly, for propagating contact line in wetting, where irreversibility is weaker than in fracture, the experimental results are close to 0.5, while for fracture the reported values of 0.55--0.65 are higher.

A method for long-term corrected probabilistic Vref estimation
Creators: name: Winterfeldt, Jörg

Publisher: name: Zenodo
Year: 2022

description: Accurate estimation of the 50-year return extreme wind speed (Vref) based on sufficiently long duration wind data is important for accurate characterization of wind turbine storm loads. Often times though there is only a limited amount of site measurement data available, typically in the order of one year of data, leading to unsatisfactory levels of accuracy in the estimated Vref. GE developed a new method to overcome this problem by combining on-site wind speed measurements in combination with more long-term regional wind data in a Bayesian framework. Two inputs are used for the new Bayesian Vref estimation method:
 1.A Vref distribution using wind velocity measurements from the actual site.
 2.Prior belief: Vref distribution derived from longer duration data for a nearby site which is climatologically similar to the one under investigation. This dataset will serve as long-term correction. The Bayesian algorithm combines both inputs and computes the posterior Vref distribution at the site, a long-term corrected probabilistic determination of Vref. Results show that the method reduces the uncertainties in Vref estimation which in turn reduces uncertainty in the wind turbine site suitability assessment.
