Ways of mattering and meeting student needs in alternative high school programs
Creators: name: Norton, David William
Publisher: name: University of British Columbia
Year: 2009

description: This study examined how students report the relationship between feelings of mattering at school and how their needs are being met while at school. The study included 134 students, in grades nine through twelve, in five alternative programs in Vancouver, B.C. The meeting of students needs and the measurement of perceptions of mattering were determined through the use of two questionnaires. The instrument measuring needs fulfilment employed scales relating to security, social, esteem and self actualization needs. The questionnaire measuring perceptions of mattering utilized scales measuring perceptions of importance, attention, dependence and ego - extension. The results showed strong correlations between the meeting of student needs and perceptions of mattering while in attendance at school.
Bound-to-continuum potential model for the $(p,γ)$ reactions of the CNO cycle

description: The study of CNO cycle involves the examination of the proton radiative capture, or the $(p,γ)$ reactions below 2 MeV. The astrophysical $\mathcal{S}$ factor characterizing the $(p,γ)$ reaction is usually reduced to the electric dipole transition $E1$ from the scattering state to the bound state. In this work, the partial scattering and the single-particle bound wave functions in the reduced matrix element of the transition are obtained from the single self-consistent mean-field potential deduced from the Skyrme Hartree-Fock calculation. The astrophysical $\mathcal{S}$ factors of the $(p,γ)$ reactions in the CNO cycle were successfully reproduced. The self-consistent Hartree-Fock calculation from the discrete to the continuum is a promising approach for the microscopic analysis of the nucleon-induced reactions in nuclear astrophysics.

description: This project explores the representation of Miss Havisham in Dickens’s Great Expectations and in cinematic adaptations of the 20th and 21st century through the gothic, sensationalist and melodramatic artistic modes. I will examine how the Victorian spinster is imagined by Dickens in the novel and how it was shaped by earlier writings. Moving on to Dickensian cinematic afterlives, I will explore how this image in transformed in films that reflect contemporary popular culture and our own perception of the Victorians. I refer to David Lean’s classic masterpiece Great Expectations (1946) as a brilliant example for all films that follow and I adopt a postmodern and neo-Victorian approach to examine the most recent adaptations: Brian Kirk’s Great Expectations (2011) and Mike Newell’s Great Expectations (2012); however, my interest in contemporary representations of grotesque jilted brides does not stop at films based on Dickens’s novel. I consider animation equally important and therefore I will also refer to Tim Burton’s Corpse Bride (2005) as another film that reflects on Miss Havisham in a dark and humorous way.
description: Η διατριβή αυτή διερευνά την αναπαράσταση της Μις Χάβισαμ στις Μεγάλες Προσδοκίες του Dickens και σε κινηματογραφικές προσαρμογές του 20ου και 21ου αιώνα μέσα από γκόθικ, αισθησιοκρατικές και μελοδραματικές καλλιτεχνικές προσεγγίσεις. Θα εξετάσω πώς παρουσιάζεται η βικτοριανή γεροντοκόρη που φαντάστηκε ο Dickens στο μυθιστόρημα καθώς και πώς διαμορφώθηκε από προηγούμενες γραφές. Προχωρώντας στις κινηματογραφικές αναπαραστάσεις στην μετά του Dickens εποχή, θα διερευνήσω το πώς αυτή η εικόνα μεταφέρεται σε ταινίες που απεικονίζουν τη σύγχρονη λαϊκή κουλτούρα και τη δική μας αντίληψη των Βικτωριανών. Αναφέρομαι στο κλασικό αριστούργημα Μεγάλες Προσδοκίες (1946) του David Lean ως ένα λαμπρό παράδειγμα για όλες τις ταινίες που ακολουθούν και υιοθετώ μια μεταμοντέρνα και νεο-βικτοριανή προσέγγιση για να εξετάσω τις πιο πρόσφατες προσαρμογές: Μεγάλες Προσδοκίες (2011) του Brian Kirk και Μεγάλες Προσδοκίες (2012) του Mike Newell. Ωστόσο, το ενδιαφέρον μου για τις σύγχρονες γκροτέσκο αναπαραστάσεις της προδομένης νύφης δεν σταματούν σε ταινίες βασισμένες στο μυθιστόρημα του Dickens. Θεωρώ τις ταινίες κινουμένων σχεδίων εξίσου σημαντικές και ως εκ τούτου θα αναφερθώ, επίσης, στο Corpse Bride (2005) του Tim Burton, ως μια ακόμα ταινία που αναπαριστά την Μις Χάβισαμ με ένα σκοτεινό και χιουμοριστικό τρόπο.

description: Motivated by the electroweak hierarchy problem, we consider theories with two extra dimensions in which the four-dimensional scalar fields are components of gauge boson in full space. We explore the Nielsen-Olesen instability for SU(N) on a torus, in the presence of a magnetic background. A field theory approach is developed, computing explicitly the minimum of the complete effective potential, including tri-linear and quartic couplings and determining the symmetries of the stable vacua. We also develop appropriate gauge-fixing terms when both Kaluza-Klein and Landau levels are present and interacting, discussing the interplay between the possible six and four dimensional choices. The equivalence between coordinate dependent and constant Scherk-Schwarz boundary conditions -associated to either continuous or discrete Wilson lines- is analyzed.

Στα δίκτυα πληροφορίας οι παρούσες σχέσεις των κόμβων μπορεί να είναι του ίδιου τύπου ή διαφορετικού. Αυτός ο ετερογενής χαρακτήρας τους επιζητά ειδική προσέγγιση για την αποτελεσματική κατηγοριοποίηση των κόμβων τους, η οποία επιτυγχάνεται με την χρήση συλλογικών αλγορίθμων, δηλαδή αλγορίθμων που εκμεταλλεύονται όλες τις κρυφές και μη εξαρτήσεις των αντικειμένων ενός γράφου. Ενώ οι σχέσεις των κόμβων συχνά είναι άμεσα δηλωμένες, υπάρχουν και γράφοι οι οποίοι μπορούν να δημιουργηθούν από δεδομένα με έμμεσες σχέσεις. Στο πλαίσιο αυτής της εργασίας εξετάσαμε την βιβλιογραφία και ανακαλύψαμε τους γνωστότερους συλλογικούς αλγορίθμους, τους οποίους και υλοποιήσαμε. Στην συνέχεια εφαρμόσαμε αυτούς τους αλγορίθμους σε έναν αριθμό συνόλων δεδομένων χρησιμοποιώντας έναν υπονοούμενο γράφο που σχηματίζεται από την έννοια των κοντινότερων γειτόνων ενός κόμβου.

description: Data that is present in great quantities all over the web and in large databases tend to organize themselves in dynamic, time evolving structures that are frequently studied as graphs or information networks. The relational information that exists between this kind of data can present an important advantage for Knowledge Discovery procedures, with correct usage. In information networks, present relations can be of the same or different type. This heterogeneous characteristic needs special attention for the efficient classification of nodes, which can be achieved by using collective algorithms, namely algorithms that take advantage of all, hidden or not dependencies of graph objects. While relations in graphs are usually explicit, there are graphs that can be created by data with implicit relations. In this thesis, we studied related work and investigated the most well-known collective algorithms, which we developed. After that, we applied those algorithms to a number of datasets, using an implicit graph that forms out of each node’s nearest neighbors. This comparison against two known algorithms showed promising results for the usage of collective algorithms and graphs in classification.

description: We study the possibility to bind eight quarks in a molecular hadronic system composed of two nucleons and an antikaon, with the quantum numbers of a hexaquark flavour, in particular with strangeness -1, isospin 1/2, parity -, baryonic number 2 and two possible spins, 0 or 1. These exotic hadrons are motivated by the deuteron, a proton-neutron boundstate, and by the model of the Lambda(1405) as an antikaon proton boundstate. We discuss the possible production of this hadron in the experiments which are presently investigating hot topics like the Theta+ pentaquark or the K- deeply bound in nuclei. The K- N interactions and the coupling to other channels are computed microscopically from a confining and chiral invariant quark model resulting in local plus separable Gaussian potentials. The N N interactions used here are the state of the art Nijmegen potentials. The binding energy and the decay rate of the K- N and K- N N systems are computed with configuration space variational methods. The only systems that bind with our microscopic interaction are the K- N in the I=0 channel and the K- N N in the S=0 channel.

description: We perform a consistent comparison of the mass and mass profiles of massive ($M_\star > 10^{11.4}M_{\odot}$) central galaxies at z~0.4 from deep Hyper Suprime-Cam (HSC) observations and from the Illustris, TNG100, and Ponos simulations. Weak lensing measurements from HSC enable measurements at fixed halo mass and provide constraints on the strength and impact of feedback at different halo mass scales. We compare the stellar mass function (SMF) and the Stellar-to-Halo Mass Relation (SHMR) at various radii and show that the radius at which the comparison is performed is important. In general, Illustris and TNG100 display steeper values of $α$ where $M_{\star}\propto M_{\rm vir}^α$. These differences are more pronounced for Illustris than for TNG100 and in the inner rather than outer regions of galaxies. Differences in the inner regions may suggest that TNG100 is too efficient at quenching in-situ star formation at $M_{\rm vir}\simeq10^{13} M_{\odot}$ but not efficient enough at $M_{\rm vir}\simeq10^{14} M_{\odot}$. The outer stellar masses are in excellent agreement with our observations at $M_{\rm vir}\simeq10^{13} M_{\odot}$, but both Illustris and TNG100 display excess outer mass as $M_{\rm vir}\simeq10^{14} M_{\odot}$ (by ~0.25 and ~0.12 dex, respectively). We argue that reducing stellar growth at early times in $M_\star \sim 10^{9-10} M_{\odot}$ galaxies would help to prevent excess ex-situ growth at this mass scale. The Ponos simulations do not implement AGN feedback and display an excess mass of ~0.5 dex at $r<30$ kpc compared to HSC which is indicative of over-cooling and excess star formation in the central regions. Joint comparisons between weak lensing and galaxy stellar profiles are a direct test of whether simulations build and deposit galaxy mass in the correct dark matter halos and thereby provide powerful constraints on the physics of feedback and galaxy growth.

description: We determine the optimal method of discriminating and comparing quantum states from a certain class of multimode Gaussian states and their mixtures when arbitrary global Gaussian operations and general Gaussian measurements are allowed. We consider the so-called constant-$\hat{p}$ displaced states which include mixtures of multimode coherent states arbitrarily displaced along a common axis. We first show that no global or local Gaussian transformations or generalized Gaussian measurements can lead to a better discrimination method than simple homodyne measurements applied to each mode separately and classical postprocessing of the results. This result is applied to binary state comparison problems. We show that homodyne measurements, separately performed on each mode, are the best Gaussian measurement for binary state comparison. We further compare the performance of the optimal Gaussian strategy for binary coherent states comparison with these of non-Gaussian strategies using photon detections.

Here, we present key indicative research questions under four research themes. We identified and prioritised these themes by analysing data from workshops and interviews with key educational stakeholders who are working in the context of Myanmar. We encourage readers to consult the full research agenda report, in which we provide an extensive discussion of the methodology, description of the context, and detailed sub-questions that could be relevant to researchers. We reviewed education evidence to identify gaps in knowledge about education during Myanmar’s conflict (Rinehart et al, 2024a). We used these findings to inform our research agenda.We intend for the research agenda to build a stronger foundation of evidence for understanding how diverse actors design and deliver education for ethnic, refugee and migrant children. The research agenda uses the ERICC conceptual framework (Kim et al, 2024) to situate the research themes and aims. This ensures that the research is intentionally organised within a theoretical understanding of education within conflict and crisis settings.

description: The established techniques for legal-for-trade registration of weight values meet the legal requirements, but in praxis they show serious disadvantages. We report on the first implementation of intrinsically legal-for-trade objects, namely weight values signed by the scale, that is accepted by the approval authority. The strict requirements from both the approval- and the verification-authority as well as the limitations due to the hardware of the scale were a special challenge. The presented solution fulfills all legal requirements and eliminates the existing practical disadvantages.

Stellar ages, masses and bolometric luminosities were derived from internal structure models. Without taking into account for the effects of gravity darkening, we notice the occurrence of the Be phenomenon in later stages of main sequence phase.

description: We investigate the source detection problem in epidemiology, which is one of the most important issues for control of epidemics. Mathematically, we reformulate the problem as one of identifying the relevant component in a multivariate Gaussian mixture model. Focusing on the study of cholera and diseases with similar modes of transmission, we calibrate the parameters of our mixture model using human mobility networks within a stochastic, spatially explicit epidemiological model for waterborne disease. Furthermore, we adopt a Bayesian perspective, so that prior information on source location can be incorporated (e.g., reflecting the impact of local conditions). Posterior-based inference is performed, which permits estimates in the form of either individual locations or regions. Importantly, our estimator only requires first-arrival times of the epidemic by putative observers, typically located only at a small proportion of nodes. The proposed method is demonstrated within the context of the 2000-2002 cholera outbreak in the KwaZulu-Natal province of South Africa.

description: The combination of phase, intensity, and contrast effects during electrooptic modulation is theoretically and exper- imentally investigated. One consequence of this combination is the modification of the amplitude of the single-frequency signals which are commonly used as working points for electrooptic mod- ulators and for the measurements of the electrooptic coefficients. Another consequence of direct intensity modulation is to shift the double-frequency points of the transfer function from the positions they normally occupy at the intensity extrema. They can even make them disappear if the direct intensity modulation is stronger than the phase modulation. Such phenomena are expected with any ferroelectric material in which a significant part of the incident light is deflected or scattered by domain walls or grain boundaries. They can lead to considerable mistakes in the determination of the electrooptic coefficients. Appropriate procedures to extract the different contributions are explained. Experimental results in rubidium hydrogen selenate are given, and consequences of the working of electrooptic modulators are discussed.
On Polyhedral Realization with Isosceles Triangles

description: Answering a question posed by Joseph Malkevitch, we prove that there exists a polyhedral graph, with triangular faces, such that every realization of it as the graph of a convex polyhedron includes at least one face that is a scalene triangle. Our construction is based on Kleetopes, and shows that there exists an integer $i$ such that all convex $i$-iterated Kleetopes have a scalene face. However, we also show that all Kleetopes of triangulated polyhedral graphs have non-convex non-self-crossing realizations in which all faces are isosceles. We answer another question of Malkevitch by observing that a spherical tiling of Dawson (2005) leads to a fourth infinite family of convex polyhedra in which all faces are congruent isosceles triangles, adding one to the three families previously known to Malkevitch. We prove that the graphs of convex polyhedra with congruent isosceles faces have bounded diameter and have dominating sets of bounded size.

description: We have studied the Fano effect in a few-electron quantum dot side-coupled to a quantum wire. The conductance of the wire, which shows an ordinal staircase-like quantization without the dot, is modified through the interference (the Fano effect) and the charging effects. These effects are utilized to verify the exhaustion of electrons in the dot. The "addition energy spectrum" of the dot shows a shell structure, indicating that the electron confinement potential is fairly circular. A rapid sign inversion of the Fano parameter on the first conductance plateau with the change of the wire gate voltage has been observed, and explained by introducing a finite width of dot-wire coupling.

description: Context. In order to understand the evolution of molecular clouds it is important to identify the departures from self-similarity associated with the scales of self-gravity and the driving of turbulence. Aims. A method is described based on structure functions for determining whether a region of gas, such as a molecular cloud, is fractal or contains structure with characteristic scale sizes. Methods. Using artificial data containing structure it is shown that derivatives of higher order structure functions provide a powerful way to detect the presence of characteristic scales should any be present and to estimate the size of such structures. The method is applied to observations of hot H2 in the Kleinman-Low nebula, north of the Trapezium stars in the Orion Molecular Cloud, including both brightness and velocity data. The method is compared with other techniques such as Fourier transform and histogram techniques. Results. It is found that the density structure, represented by H2 emission brightness in the K-band (2-2.5micron), exhibits mean characteristic sizes of 110, 550, 1700 and 2700AU. The velocity data show the presence of structure at 140, 1500 and 3500AU. Compared with other techniques such as Fourier transform or histogram, the method appears both more sensitive to characteristic scales and easier to interpret.

description: Στην παρούσα διπλωματική εργασία μελετήθηκαν οι οπτικές ιδιότητες αιωρούμενων σωματιδίων ερήμου σε 15 περιοχές περιμετρικά της Μεσογείου. Για τις 15 περιοχές μελέτης, ο αισθητήρας MODIS παρείχε καθημερινές μετρήσεις για το χρονικό διάστημα Ιανουαρίου του 2000 έως και τον Δεκέμβριο του 2010. Ο MODIS παρείχε μετρήσεις που συμπεριλαμβανόταν το οπτικό βάθος ΑOT 550(nm), o Fine Mode Ratio 550(nm), ο συντελεστής Angstrom Ocean (550/865nm) και ο συντελεστής Angstrom Land (470/660nm) . Θέτοντας κριτήρια στις μετρήσεις, τα οποία βρέθηκαν από διεθνή βιβλιογραφία, έγινε μια προσπάθεια στατιστικής ανάλυσης για τον εντοπισμό των πιθανότερων τιμών των οπτικών ιδιοτήτων που προαναφέρθηκαν στις ημέρες επεισοδίων σκόνης από Σαχάρα. Χρησιμοποιήθηκε το μοντέλο HYSPLIT για την παρατήρηση των ανάδρομων τροχιών των σωματιδίων και για την επαλήθευση της πηγής προέλευσης. Στο τελικό στάδιο, έγινε συσχέτιση των μετρήσεων με δεδομένα και από το δίκτυο επίγειων μετρήσεων AERONET της NASA.
description: The aim of this thesis was the study of aerosol optical properties in 15 Mediterranean cities. Moderate Resolution Imaging Spectroradiometer (MODIS) provided daily measurements from January 2000 to December 2010. MODIS measurements included optical depth AOD 550(nm), Fine Mode Ratio 550(nm), Angstrom Coefficient/Οcean (550/865nm) and Angstrom Coefficient/Land (470/660nm). By setting limits to measurements, from national bibliography, an effort was made to estimate the most common rates for optical properties and statistical analysis for Sahara desert dust episodes. HYSPLIT model was used to observed backward trajectory direction and verify the source. In the end, a correlation took place to compare satellite data to ground based measurements from AERONET/NASA.

description: In the past few decades, to reduce the risk of X-ray in computed tomography (CT), low-dose CT image denoising has attracted extensive attention from researchers, which has become an important research issue in the field of medical images. In recent years, with the rapid development of deep learning technology, many algorithms have emerged to apply convolutional neural networks to this task, achieving promising results. However, there are still some problems such as low denoising efficiency, over-smoothed result, etc. In this paper, we propose the Edge enhancement based Densely connected Convolutional Neural Network (EDCNN). In our network, we design an edge enhancement module using the proposed novel trainable Sobel convolution. Based on this module, we construct a model with dense connections to fuse the extracted edge information and realize end-to-end image denoising. Besides, when training the model, we introduce a compound loss that combines MSE loss and multi-scales perceptual loss to solve the over-smoothed problem and attain a marked improvement in image quality after denoising. Compared with the existing low-dose CT image denoising algorithms, our proposed model has a better performance in preserving details and suppressing noise.

Tension dynamics in semiflexible polymers. Part I: Coarse-grained equations of motion

description: Based on the wormlike chain model, a coarse-grained description of the nonlinear dynamics of a weakly bending semiflexible polymer is developed. By means of a multiple scale perturbation analysis, a length-scale separation inherent to the weakly-bending limit is exploited to reveal the deterministic nature of the spatio-temporal relaxation of the backbone tension and to deduce the corresponding coarse-grained equation of motion. From this partial integro-differential equation, some detailed analytical predictions for the non-linear response of a weakly bending polymer are derived in an accompanying paper (Part II, cond-mat/0609638).

Casual attributions and the search for a sense of purpose in women with inflammatory arthritis
Creators: name: Miller, Vaughan
Publisher: name: University of British Columbia
Year: 2009

description: This study sought to understand the ways in which women with inflammatory arthritis, including rheumatoid arthritis (RA), juvenile rheumatoid arthritis (JRA), and psoriatic arthritis(PA), developed their own causal models over the course of their illness, and the ways in which the elements of these causal models influenced the way they live their lives. By asking patients "why do you think you got arthritis ? " and by tracing the route these patients took in arriving at their causal conclusions, the world views of the coinvestigators were revealed, to some extent, as were the ways in which these world views had been modified in order to make sense of chronic illness. This study included 12 co-investigators, and took a qualitative approach. Repeated in-depth, open-ended interviews were conducted with each co-investigator, and data is presented here in the form of life schemes. Data analysis involved an examination of similarities and differences across stories, and a determination of the kinds of events that influence the formation of causal conclusions. This study found that the causal models of the coinvestigators developed in a fairly typical manner, starting first with physical causes, then expanding to incorporate psychological causes, then expanding further to a consideration of existential explanations. A general story was written to synthesize the information, and to show the overall pattern of development of the causal models. Within the general story differences across causal models are highlighted, as are the different meanings assigned to the same causal attribution by different co-investigators.

description: We analyze the quantum consistency of anomalous abelian models and of their effective field theories, rendered anomaly-free by a Wess-Zumino term, in the case of multiple abelian symmetries. These models involve the combined Higgs-Stuckelberg mechanism and predict a pseudoscalar axion-like field that mixes with the goldstones of the ordinary Higgs sector. We focus our study on the issue of unitarity of these models both before and after spontaneous symmetry breaking and detail the set of Ward identities and the organization of the loop expansion in the effective theory. The analysis is performed on simple models where we show, in general, the emergence of new effective vertices determined by certain anomalous interactions.

description: We prove that the Waldhausen Nil-group associated to a virtually cyclic groups that surjects onto the infinite dihedral group vanishes if and only if the corresponding Farrell Nil-group associated to the canonical index two subgroup is trivial. The proof uses the transfer map to establish one direction, and uses controlled pseudo-isotopy techniques of Farrell-Jones to establish the reverse implication.

description: The purpose of the present chapter is to bind together and extend some recent developments regarding data-driven non-smooth regularization techniques in image processing through the means of a bilevel minimization scheme. The scheme, considered in function space, takes advantage of a dualization framework and it is designed to produce spatially varying regularization parameters adapted to the data for well-known regularizers, e.g. Total Variation and Total Generalized variation, leading to automated (monolithic), image reconstruction workflows. An inclusion of the theory of bilevel optimization and the theoretical background of the dualization framework, as well as a brief review of the aforementioned regularizers and their parameterization, makes this chapter a self-contained one. Aspects of the numerical implementation of the scheme are discussed and numerical examples are provided.

description: We characterized the S14160-3050HS Multi-Pixel Photon Counter (MPPC), a high efficiency, single channel silicon photomultiplier manufactured by Hamamatsu Photonics K.K. All measurements were performed at a room temperature of (23.0 $\pm$ 0.3) $^{\circ}$C. We obtained an I-V curve and used relative derivatives to find a breakdown voltage of 38.88 V. At a 3 V over voltage, we find a dark count rate of 1.08 MHz, crosstalk probability of 21 $\%$, photon detection efficiency of 55 $\%$ at 450 nm, and saturation at 1.0x10$^{11}$ photons per second. The S14160-3050HS MPPC is a candidate detector for the Ultra-Fast Astronomy (UFA) telescope which will characterize the optical (320 nm - 650 nm) sky in the millisecond to sub-microsecond timescales using two photon counting arrays operated in coincidence on the 0.7 meter Nazarbayev University Transient Telescope at the Assy-Turgen Astrophysical Observatory (NUTTelA-TAO) located near Almaty, Kazakhstan. We discuss advantages and disadvantages of using the S14160-3050HS MPPC for the UFA telescope and future ground-based telescopes in sub-second time domain astrophysics.

description: Tο Παζάρ χαμάμ ή αλλιώς Γιαχουντί χαμάμ της Θεσσαλονίκης ,θα πρέπει να οικοδομήθηκε στις αρχές του 16ου αιώνα, ενώ ιδρυτής του ήταν ο Χαλίλ Αγά. Το Yahudi hamami έχει τη χαρακτηριστική διάρθρωση χώρου των οθωμανικών λουτρών της κλασικής περιόδου, και είναι χτισμένο από πέτρα και πλίνθους, εξωτερικά με πλινθοπερίκλειστο τρόπο δόμησης, που μιμείται το βυζαντινό. Αντικείμενο της παρούσας μεταπτυχιακής διατριβής είναι η τρισδιάστατη αποτύπωση με σαρωτή laser στο Παζάρ Χαμάμ. Αρχικά γίνεται μια σύντομη αναφορά στους τύπους και τη λειτουργία των οθωμανικών λουτρών γενικότερα, προκειμένου να γίνει κατανοητή η ανάλυση των αρχιτεκτονικών στοιχείων του λουτρού. Έπειτα, παρουσιάζονται οι μέθοδοι γεωμετρικής τεκμηρίωσης των μνημείων με έμφαση σε αυτή της τρισδιάστατης αποτύπωσης που εφαρμόστηκε και αναλύονται οι αρχές λειτουργίας των οργάνων και η διαδικασία επεξεργασίας ως το τελικό αποτέλεσμα. Μέσα από το τελικό αποτέλεσμα, που είναι τα σχέδια κατόψεων, όψεων, άνοψης και τομών του μνημείου, εξάγονται κάποια συμπεράσματα για την επιλογή της κατάλληλης μεθόδου. Τέλος, παρουσιάζεται ένα βίντεο περιήγησης μέσα από το πρόγραμμα στο οποίο έγινε η επεξεργασία, για το εν λόγω μνημείο, στο οποίο η αδυναμία πρόσβασης σήμερα καθιστά δύσκολη τη γνωριμία του με το κοινό.
description: Bazaar Hamam (Yahudi) of Thessaloniki was built in the early 16th century and the founder was Khalil Agha. Yahudi hamami has the characteristic structure of the classical period’s Ottoman baths, and is built of stone and brick, with cloisonne exterior construction method that mimics the Byzantine method. The object of this master thesis is the three-dimensional mapping with laser scanner of Bazaar Hamam. In the beginning was made a brief reference to the types and operation of Ottoman baths in general, in order to understand the analysis of the architectural elements of the bathroom. Then, a presentation takes place of the geometric documentation of monuments with emphasis on three-dimensional method that was applied. Furthermore, the operating principles of the instrument and the process of the data are being analyzed. Through the final results, which are the floor plans, sides, bottom and sections of the monument, the appropriate method is chosen. Finally, a video tour was made through the used program, in order to make it easier for the public to see the inside of the monument.

description: A new method is presented, that can help a person become aware of his or her unconscious preferences, and convey them to others in the form of verbal explanation. The method combines the concepts of reflection, visualization, and verbalization. The method was tested in an experiment where the unconscious preferences of the subjects for various artworks were investigated. In the experiment, two lessons were learned. The first is that it helps the subjects become aware of their unconscious preferences to verbalize weak preferences as compared with strong preferences through discussion over preference diagrams. The second is that it is effective to introduce an adjustable factor into visualization to adapt to the differences in the subjects and to foster their mutual understanding.

description: The manifesto of the current article is to investigate the compact anisotropic matter profiles in the context of one of the modified gravitational theories, known as $f(\mathcal{R}, \mathcal{T})$ gravity, where $\mathcal{R}$ is a Ricci Scalar and $\mathcal{T}$ is the trace of the energy-momentum tensor. To achieve the desired goal, we capitalized on the spherical symmetric space-time and utilized the embedding class-1 solution via Karmarkar's condition in modeling the matter profiles. To calculate the unidentified constraints, Schwarzschild exterior solution along with experimental statistics of three different stars LMC X-4, Cen X-3, and EXO 1785-248 are taken under consideration. For the evaluation of the dynamical equations, a unique model $f(\mathcal{R}, \mathcal{T})=\mathcal{R}+β\mathcal{R}^2+λ\mathcal{T}$ has been considered, with $β$ and $λ$ being the real constants. Different physical aspects have been exploited with the help of modified dynamical equations. Conclusively, all the stars under observations are realistic, stable, and are free from all singularities.
