description: Τα χαρισματικά παιδιά, καθώς και τα παιδιά με σύνδρομο Asperger, μεγαλώνουν χωρίς πολλές φορές να γίνει σωστή εκτίμηση της πραγματικής γνωστικής τους κατάστασης, με αποτέλεσμα να υπάρχουν λανθασμένες εντυπώσεις, τόσο από την πλευρά των γονέων, και των εκπαιδευτικών, όσο και των κλινικών ψυχολόγων. Γίνεται, επομένως κατανοητό ότι, η εστίαση στις λεπτές εκείνες γραμμές που διαχωρίζουν τις διαστάσεις χαρισματικότητας από τα χαρακτηριστικά του συνδρόμου Asperger, απαιτεί ακόμη περισσότερη προσοχή και συστηματική παρατήρηση, από μέρους των ατόμων που αλληλεπιδρούν με αυτήν την ειδική ομάδα μαθητών. Οποιαδήποτε λάθος εκτίμηση μπορεί να έχει αρνητικές συνέπειες στην γνωστική, κοινωνική, αλλά και συναισθηματική ανάπτυξη των παιδιών αυτών επηρεάζοντας την μετέπειτα ζωή τους, αλλά και αποκλείοντας τα από μια ενισχυτική παρέμβαση. Η γλώσσα, η οποία αποτελεί το σημαντικότερο μέσο έκφρασης, μπορεί στη περίπτωση αυτών των παιδιών, να αποτελέσει τροχοπέδη και να δυσχεράνει το έργο των ατόμων που ασχολούνται με αυτές τις ομάδες στο να εκτιμήσουν σωστά μια κατάσταση. Η πρώιμη και κατάλληλη παρέμβαση στο χώρο του σχολείου μπορεί να συμβάλλει θετικά στην ενίσχυση και καλλιέργεια των μηχανισμών εκείνων που θα βελτιώσουν την ποιότητα της καθημερινότητάς τους.Σκοπός της παρούσας εργασίας είναι η συγκέντρωση πληροφοριών σχετικά με τη συνύπαρξη χαρισματικότητας και συνδρόμου Asperger, μέσα από πρόσφατα δημοσιευμένες ερευνητικές μελέτες
description: Gifted children, as well as children with Asperger's syndrome, often grow to make a correct assessment of their actual cognitive status, resulting in false impressions from both parents, educators and clinical psychologists. It is therefore understandable that focusing on those subtle lines separating the giftedness dimensions from the characteristics of Asperger's syndrome requires even more attention and systematic observation on the part of those interacting with this special group of students.Any mistaken assessment may have a negative impact on the cognitive, social, and emotional development of these children by influencing their later life, but excluding them from a reinforcing intervention. Language, which is the most important means of expression, can, in the case of these children, hamper and hamper the work of those working with these groups to properly assess a situation. Early and appropriate intervention in school can contribute positively to strengthening and cultivating those mechanisms that will improve the quality of their everyday life. The purpose of this work is to gather informations on the coexistence of giftedness and Asperger syndrome, through recently published research studies

description: We have performed accurate calculations of the hyperfine structure of the $2\,^3\!P$ state in the $^9$Be atom with the help of highly optimized, explicitly correlated functions, accounting for the leading finite nuclear mass, radiative, nuclear structure and relativistic effects. By comparison with measurements, we have determined the $^9$Be nuclear quadrupole moment to be $Q_{\rm N} = 0.05350(14)$ barns, which is not only the most accurate result, but also disagrees with previous determinations.

description: Young stars accrete material from their circumstellar disk through magnetically-controlled funnel flows. This so-called magnetospheric accretion process is central to the properties of young systems and not yet fully deciphered. We report here on an attempt to directly probe the star-disk interaction region a scale of less than 0.1 au in the young system DoAr 44, using with VLTI/GRAVITY in the K-band. We computed interferometric visibilities and phases in the continuum and in the Br$\gamma$ line in order to constrain the extent and geometry of the emitting regions. We resolve the continuum emission of the inner dusty disk and measure a half-flux radius of 0.14 au. We show that Br$\gamma$ emission arises from an even more compact region than the inner disk, with an upper limit of 0.047 au (∼5 R$_\star$). Differential phase measurements between the Br$\gamma$ line and the continuum allow us to measure the astrometric displacement of the Br$\gamma$ line-emitting region relative to the continuum on a scale of a few tens of microarcsec, corresponding to a fraction of the stellar radius. Our results can be accounted for by a simple geometric model where the Br$\gamma$ line emission arises from a compact region interior to the inner disk edge, on a scale of a few stellar radii, fully consistent with the concept of magnetospheric accretion process in low-mass young stellar systems.

description: In the Color Glass Condensate (CGC) effective field theory, colliding sheets of Colored Glass form a strongly interacting, non-equilibrium state called the Glasma. How Colored Glass shatters to form the Glasma, the properties of the Glasma, and how the Glasma thermalizes into a Quark Gluon Plasma(QGP) are questions of central interest in understanding the properties of the strongly interacting matter produced in heavy ion collisions. We argue that these questions can be addressed in the framework of field theories with strong time dependent external sources. Albeit such field theories are non-perturbative for arbitrarily weak coupling, moments of the multiplicity distribution can be computed systematically in powers of the coupling constant. We demonstrate that the average multiplicity can be (straightforwardly) computed to leading order in the coupling and (remarkably) to next-to-leading order as well. We relate our formalism to results from previous 2+1 and 3+1 dimensional numerical simulations of the Glasma fields. The expanding Glasma is unstable; small fluctuations in the initial conditions grow exponentially with the square root of the proper time. Whether this explosive growth leads to early thermalization in heavy ion collisions requires at present a better understanding of these fluctuations on the light cone. In the final lecture, motivated by recent work of Bialas and Jezabek, we discuss the widely observed phenomenon of limiting fragmentation in the CGC framework.

description: In situations of public display or high perceived importance of evaluation, fear of failure directs many students into adopting self-handicapping behaviors to protect their academic image. Drawing from Self-determination Theory, the aim of the present study was to examine the role of students’ motivation on the use of self-handicapping techniques during secondary school physical education lessons. The sample of the study consisted of 246 secondary school students (116 males and 130 females, M age = 14.11, SD=.91) attending six different typical coeducational schools in Western Greece. The results of the regression analyses indicated that controlled motivational climate, students’ basic psychological need thwarting, particularly competence thwarting, and extrinsic motivation positively predicted the use of self-handicapping strategies during physical education lessons. Furthermore, students’ psychological need satisfaction and identified regulation were negative predictors of the use of self-handicapping strategies. No significant gender differences in use of self-handicapping behaviors were found. The findings of the study support the basic tenets of the Self-determination theory and highlight the importance of physical education teacher initiated motivational climate.

description: A major advance in density-matrix renormalization group (DMRG) calculations has been achieved by the invention of highly efficient DMRG techniques for the simulation of real-time dynamics of strongly correlated quantum systems in one dimension. Starting from established linear-response techniques in DMRG and early attempts at real-time dynamics, we go on to review two current methods which both implement the idea of adapting the effective Hilbert space of DMRG to the quantum state evolving in time. We also give an outlook on extensions to finite temperature calculations.

Performance, emissions and combustion characteristics of natural gas fueling of diesel engines
Creators: name: Douville, Brad
Publisher: name: University of British Columbia
Year: 2009

description: The performance, emissions and combustion characteristics of natural gas fueling of diesel engines have been investigated. The natural gas fueling system employs electronically-controlled late-cycle direct injection of high pressure natural gas with a small amount of diesel fuel (diesel pilot). Since the temperature in the combustion chamber at the end of compression is below the autoignition temperature of natural gas, the diesel pilot is required for ignition. Diesel engine performance and emissions have been measured using both natural-gas and conventional diesel fueling, over a wide range of operating conditions. The combustion process in diesel engines has been modeled based on measured cylinder pressure to learn about the formation rates of oxides of nitrogen and fuel burning rates. This combustion model has been developed to deal specifically with the non-uniformities and pollutant formation associated with stratified-charge combustion in diesel engines. The test results demonstrate that the thermal efficiencies for both natural gas and conventional diesel fueling at low and medium engine loads, are almost identical. The thermal efficiencies at high loads for natural gas fueling are greater than for conventional diesel fueling. Upon optimization of the natural gas and diesel pilot injection, lower pollutant exhaust emissions will be produced over the entire engine load range, while obtaining higher peak engine load capabilities than with conventional diesel fueling.

description: We report on the magnetic properties of thoroughly characterized Zn1-xCoxO epitaxial thin films, with low Co concentration, x=0.003-0.005. Magnetic and EPR measurements, combined with crystal field theory, reveal that isolated Co2+ ions in ZnO possess a strong single ion anisotropy which leads to an "easy plane" ferromagnetic state when the ferromagnetic Co-Co interaction is considered. We suggest that the peculiarities of the magnetization process of this state can be viewed as a signature of intrinsic ferromagnetism in ZnO:Co materials.

description: In a previous paper, we showed nonvaninishing of the universal index elements in the K-theory of the maximal C*-algebras of the fundamental groups of enlargeable spin manifolds. The underlying notion of enlargeability was the one from the first relevant paper of Gromov and Lawson, involving contracting maps defined on finite covers of the given manifolds. In the paper at hand, we weaken this assumption to the one in the second paper of Gromov and Lawson, where infinite covers are allowed. The new idea is the construction of a geometrically given C*-algebra with trace which encodes the information given by these infinite covers; along the way we obtain an easy proof of a relative index theorem relevant in this context.

description: We find new explicit solutions describing closed strings spinning with equal angular momentum in two independent planes in the $AdS_5$ black hole spacetime. These are $2n$ folded strings in the radial direction and also winding $m$ times around an angular direction. We especially consider these solutions in the long string and high temperature limit, where it is shown that there is a logarithmic correction to the scaling between energy and spin. This is similar to the one-spin case. The strings are spinning, or actually orbiting around the black hole of the $AdS_5$ black hole spacetime, similarly to solutions previously found in black hole spacetimes.

description: In the present paper we construct an algorithmic tool for Semi-Markov modeling in the Matlab enviroment (v. 2015a). The algorithms refer to discrete homogeneous Semi-Markov Models. The purpose of this work is to create programs that will provide the user the ability to extract automatically the desired results in a minimum time. We initially study the distributions of the holding times using the maximum likelihood estimator, the Newton-Rapson method and Akaike information criterion (AIC). In the present we apply distributions for the holding times for the Semi-Markov Models as follows: the geometric distribution, the discrete Weibull distribution, the discrete Rayleigh distribution, the discrete Burr distribution and discrete Pareto distribution. Then we create the appropriate programs in the matlab enviroment so that the user can extract the desired results. Finally, by finishing our work, we implement our programs on meteorological data for the city of Athens and Thessaloniki.

description: In the physics of the Fractional Quantum Hall (FQH) effect, a zoo of Abelian topological phases can be obtained by varying the magnetic field. Aiming to reach the same phenomenology in spin-like systems, we propose a family of SU($N$)-symmetric models in the fundamental representation, on the square lattice with short-range interactions restricted to triangular units, a natural generalization for arbitrary $N$ of an SU($3$) model studied previously where time-reversal symmetry is broken explicitly. Guided by the recent discovery of SU($2$)$_1$ and SU($3$)$_1$ chiral spin liquids (CSL) on similar models we search for topological SU($N$)$_1$ CSL in some range of the Hamiltonian parameters via a combination of complementary numerical methods such as exact diagonalizations (ED), infinite density matrix renormalization group (iDMRG) and infinite Projected Entangled Pair State (iPEPS). Extensive ED on small (periodic and open) clusters up to $N=10$ and an innovative SU($N$)-symmetric version of iDMRG to compute entanglement spectra on (infinitely-long) cylinders in all topological sectors provide unambiguous signatures of the SU($N$)$_1$ character of the chiral liquids. An SU($4$)-symmetric chiral PEPS, constructed in a manner similar to its SU($2$) and SU($3$) analogs, is shown to give a good variational ansatz of the $N=4$ ground state, with chiral edge modes originating from the PEPS holographic bulk-edge correspondence. Finally, we discuss the possible observation of such Abelian CSL in ultracold atom setups where the possibility of varying $N$ provides a tuning parameter similar to the magnetic field in the physics of the FQH effect.

The power of multifractal analysis lies in its connection to higher order moments, in that it not only probes clustering on different scales but also different densities. Therefore any incompleteness issues must be correctly addressed before blindly applying this technique to real survey data.

In contrast to the extensively studied Ru4+ oxides, this compound possesses a novel Ru5+ valence state, corresponding to a half-filled t_2g_3 electron configuration. Hg2Ru2O7 exhibits a first order metal-insulator transition at 107 K, accompanied by a structural transition from cubic to lower symmetry. The behavior of the magnetic susceptibility suggests the possible formation of a spin singlet in the insulating low temperature state.

A constructive theory of shape

description: We formulate a theory of shape valid for objects of arbitrary dimension whose contours are path connected. We apply this theory to the design and modeling of viable trajectories of complex dynamical systems. Infinite families of qualitatively similar shapes are constructed giving as input a finite ordered set of characteristic points (landmarks) and the value of a continuous parameter $κ\in (0,\infty)$. We prove that all shapes belonging to the same family are located within the convex hull of the landmarks. The theory is constructive in the sense that it provides a systematic means to build a mathematical model for any shape taken from the physical world. We illustrate this with a variety of examples: (chaotic) time series, plane curves, space filling curves, knots and strange attractors.

Protons and anti-protons are less suppressed than $π^{\pm}$, in the range 1.5 $< p_{T} $ 5 GeV/c. The results at high $p_T$ indicate that the partonic sources of $π^{\pm}$, $p$ and $\bar{p}$ have similar energy loss when traversing the nuclear medium.

description: Το cloud computing είναι σχετικά νέα τεχνολογία διαχείρισης δεδομένων και αποτελεί αναπόσπαστο κομμάτι της Τεχνολογίας Πληροφοριών. Η χρήση του βασίζεται σε υπολογιστικά συστήματα τα οποία μεταφέρουν και αξιοποιούν τις πληροφορίες στο Διαδίκτυο. Το cloud ως οντότητα προσφέρει εργαλεία και δυνατότητες και μπορεί να αξιοποιηθεί από πολλούς διαθέσιμους χρήστες (επιχειρήσεις, οργανισμοί κλπ.). Ένας από αυτούς είναι και η Δασική Υπηρεσία. Η πλατφόρμα αυτή (ως ένα πολλά υποσχόμενο σύστημα) μπορεί να αναβαθμίσει τις δυνατότητες της Υπηρεσίας και να βελτιώσει τη λειτουργία της. Ο στόχος αυτής της έρευνας είναι η ανάδειξη του ζητήματος, η διεξοδική θεωρητική κάλυψή του και η πρόταση ενός μοντέλου cloud διαμορφωμένου για χρήση προς το σκοπό αυτό. Το προτεινόμενο μοντέλο μεταφέρει τις δυνατότητες της τεχνολογίας και σχηματίζει πρόσφορο έδαφος για περαιτέρω εμβάθυνση προς την κατεύθυνση αυτή.
description: Cloud computing is roughly a new data management technology and an important part of Information Technology as well. Its use is based on these computing systems that are used for information transportation and data usage on the Internet. The cloud as an entire system offers tools and capabilities and can be utilized by many available users (businesses, organizations, etc.). One of them is the Forest Service. This platform (a promising system as it is) can upgrade the Service's capabilities and improve its operation. The aim of this paper is to highlight that issue, coverage it theoretically and thoroughly and to suggest the usage of a cloud model configured for this purpose. The proposed model expresses the potential of technology and makes space for further and deeper research in this section.

Determination of stress intensity factors for laboratory test specimens using numerical methods
Creators: name: Ge, Baolai
Publisher: name: University of British Columbia
Year: 2009

description: Using the Airy stress function, plane bnear elasticity problems reduce to solving a biharmonic problem of the first type. Analytic solutions to the biharmonic problems of the first type in a domain with a re-entrant sharp corner are discussed in this thesis. General solutions to the biharmonic equation in the vicinity of the sharp corner are given in terms of a series of some special eigenfunctions, which are obtained from two auxiliary eigenvalue problems corresponding to symmetric and anti-symmetric stress states. In the case of a line crack, the leading term in each series contains the singularity in stresses near the crack tip, and its coefficient determines the stress intensity factor of Mode I or Mode II loading. In this thesis, stress intensity factors are evaluated with the specimens of two simple geometries - circular disc and rectangle - that are subjected to three types of loadings: uniformly distributed forces, concentrated forces and those yielding pure bending. Stress fields are found using the series stress functions with the boundary collocation method. The least squares approach is applied to the system of linear equations arising from the boundary collocation procedure. Compared to other sophisticated methods, the present approach employing the technique of boundary collocation is straightforward and relatively efficient in numerical computation. Numerical values of stress intensity factors are compared to the results obtained using other less efficient methods. A sound and overall agreement is found in most cases. The approach presented in this thesis along with the results may be used as an auxiliary tool to determine the fracture toughness of laboratory test specimens.
Regularization of the Factorization Method applied to diffuse optical tomography
Creators: name: Harris, Isaac
Publisher: name: arXiv
Year: 2021
Subjects: subject: Analysis of PDEs (math.AP)
subject: FOS: Mathematics

description: In this paper, we develop a new regularized version of the Factorization Method for positive operators mapping a complex Hilbert Space into it's dual space. The Factorization Method uses Picard's Criteria to define an indicator function to image an unknown region. In most applications, the data operator is compact which gives that the singular values can tend to zero rapidly which can cause numerical instabilities. The regularization of the Factorization Method presented here seeks to avoid the numerical instabilities in applying Picard's Criteria. This method allows one to image the interior structure of an object with little a priori information in a computationally simple and analytically rigorous way. Here we will focus on an application of this method to diffuse optical tomography where will prove that this method can be used to recover an unknown subregion from the Dirichlet-to-Neumann mapping. Numerical examples will be presented in two dimensions.
Josephson junctions and dark energy

description: In a recent paper Beck and Mackey [astro-ph/0603397] argue that the argument we gave in our paper [Phys. Lett. B 606, 77 (2005)] to disprove their claim that dark energy can be discovered in the Lab through noise measurements of Josephson junctions is incorrect. In particular, they emphasize that the measured noise spectrum in Josephson junctions is a consequence of the fluctuation dissipation theorem, while our argument was based on equilibrium statistical mechanics. In this note we show that the fluctuation dissipation relation does not depend upon any shift of vacuum (zero-point) energies, and therefore, as already concluded in our previous paper, dark energy has nothing to do with the proposed measurements.

Ατομική ποινική ευθύνη μελών μυστικών υπηρεσιών για παραβιάσεις διεθνούς δικαίου: μυστικές φυλακές και βασανιστήρια

description: Η παρούσα διπλωματική εργασία επιχειρεί να αναδείξει τις δυσκολίες απόδοσης ατομικής ποινικής ευθύνης στα μέλη μυστικών υπηρεσιών, όταν τα τελευταία, ενεργώντας υπό την επίσημη ιδιότητά τους κατ’ εντολή του κράτους τους, προβαίνουν στην παραβίαση κανόνων του διεθνούς δικαίου. Η ανάλυση επικεντρώνεται στις μυστικές κρατήσεις και στην τέλεση βασανιστηρίων εις βάρος υπόπτων για τρομοκρατία από μέλη, κατά κύριο λόγο, της CIA, σε συνεργασία, ορισμένες φορές, με μέλη μυστικών υπηρεσιών άλλων χωρών. Ιδιαίτερη αναφορά γίνεται στο πρόγραμμα των «extraordinary renditions» των ΗΠΑ, στο πλαίσιο του οποίου συντελούνται οι ανωτέρω παραβιάσεις. Παρά την κρισιμότητα του ζητήματος, το διεθνές δίκαιο είναι εξαιρετικά φειδωλό στις προβλέψεις του, ενώ ακόμα και οι υπάρχοντες κανόνες δυσκολεύονται να βρουν εφαρμογή, αφού πρώτον δεν θεμελιώνουν πρωτογενώς ατομική ευθύνη και δεύτερον εξαντλούνται στο να προβλέψουν την υποχρέωση των κρατών για τη δίωξη και την επιβολή ποινής στους δράστες. Τέλος, η συνδρομή των ασυλιών ratione materiae στο πρόσωπο των μελών των μυστικών υπηρεσιών, καθώς και η επίκληση από τα κράτη του «state secrets privilege» θέτει επιπρόσθετα εμπόδια στον καταλογισμό ευθύνης.
description: The purpose of the present thesis is to highlight the difficulties emmerging from the attempt to attribute individual criminal responsibility to secret agents, in cases where the latter, acting under their official capacity and following state orders, violate international law. The analysis is based on secret detentions and torture of suspected terrorists by members, mainly of the CIA, in collaboration, sometimes with members of other countries' intelligence services. Particular reference is made to the «extraordinary renditions» US program, whereby the above violations occur. Despite the seriousness of the matter, international law is too limited to projections, and even the existing rules are hardly applied since firstly they do not establish primary individual responsibility and second they are limited to providing the obligation of States to prosecute and impose punishment for the perpetrators. Finally, the assistance of immunity ratione materiae in the face of the members of the secret service, and the invocation of the states of «state secrets privilege» poses additional obstacles to the attribution of responsibility.

description: We show that finitely subgraded Lie algebras of compact operators have invariant subspaces when conditions of quasinilpotence are imposed on certain components of the subgrading. This allows us to obtain some useful information about the structure of such algebras. As an application, we prove a number of results on the existence of invariant subspaces for algebraic structures of compact operators. Along the way we obtain new criteria for the triangularizability of a Lie algebra of compact operators.

description: We present a simple two-dimensional model of a $p_x+ip_y$ superfluid in which the mass flow that gives rise to the intrinsic angular momentum is easily calculated by numerical diagonalization of the Bogoliubov-de Gennes operator. We find that, at zero temperature and for constant director $\bf l$, the mass flow closely follows the Ishikawa-Mermin-Muzikar formula ${\bf j}_{\rm mass}= \frac 12 {\rm curl} (ρ\hbar {\bf l}/2)$.

Coherent synchrotron emission from cosmic ray air showers
Creators: name: Luo, Qinghuan
Publisher: name: arXiv
Year: 2006
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Coherent synchrotron emission by particles moving along semi-infinite tracks is discussed, with a specific application to radio emission from air showers induced by high-energy cosmic rays. It is shown that in general, radiation from a particle moving along a semi-infinite orbit consists of usual synchrotron emission and modified impulsive bremsstrahlung. The latter component is due to the instantaneous onset of the curved trajectory of the emitting particle at its creation. Inclusion of the bremsstrahlung leads to broadening of the radiation pattern and a slower decay of the spectrum at the cut-off frequency than the conventional synchrotron emission. Possible implications of these features for air shower radio emission are discussed.
