description: The flux of turbulent kinetic energy from large to small spatial scales is measured in a small domain B of varying size R. The probability distribution function of the flux is obtained using a time-local version of Kolmogorov's four-fifths law. The measurements, made at a moderate Reynolds number, show frequent events where the flux is backscattered from small to large scales, their frequency increasing as R is decreased. The observations are corroborated by a numerical simulation based on the motion of many particles and on an explicit form of the eddy damping.

description: We investigate the quantum superchemistry or Bose-enhanced atom-molecule conversions in a coherent output coupler of matter waves, as a simple generalization of the two-color photo-association. The stimulated effects of molecular output step and atomic revivals are exhibited by steering the rf output couplings. The quantum noise-induced molecular damping occurs near a total conversion in a levitation trap. This suggests a feasible two-trap scheme to make a stable coherent molecular beam.

title: Drag reduction in a lubricated turbulent channel
Creators: name: Pöllinger, Alexander Matthias
Publisher: name: TU Wien
Year: 2021
Subjects: subject: Drag Reduction
subject: Turbulence
subject: Simulations

description: Direct numerical simulation (DNS) was utilized to study the drag reduction in a lubricated channel, characterized by the injection of a lubricating fluid layer in the near wall region of a planar channel to favor the transportation of the core fluid. In the present work the fluids have equal density but different viscosity, allowing for the definition of a viscosity ratio λ = η1/η2. In the scope of this work both a lubricated channel with λ = 0.01 and a single phase reference case were considered to quantify the drag reduction enabled by the lubricating layer and observe flow dynamics at large viscosity ratios. All DNS were run with a constant power input (CPI) approach. This allows for the power injected into the flow to be constant across both cases considered by adjusting the pressure gradient according to the flow rate of the channel. This was accomplished here by extending the CPI approach to lubricated channel flow. The dynamics of the liquid-liquid interface is described by a phase-field method (PFM). The simulation results indicate a significant drag reduction for the lubricated case. The flow rate increase has been quantified to be ≃ 63%. An analysis of the mean and turbulent kinetic energy budgets gives insight into the drag reduction mechanisms of the lubricated channel. For the multi-phase case, turbulence is sustained in the lubricating layer due to the local increase in Reynolds number. The core flow experiences a laminarization due to the hindering of transfer of turbulent kinetic energy from the boundary layer to the core.

The effects of targets’ shyness on perceptions of their intelligence
Creators: name: Morgan, Kathy L.
Publisher: name: University of British Columbia
Year: 2009

description: The effects of a target's shyness on others' perceptions of his/her intelligence were investigated. Subjects met weekly for 7 weeks in discussions groups of 4 or 5 members. Subjects rated all group members, including self, on intelligence, creativity, and wisdom (collectly "mental abilities"). Despite no actual relation between measured IQ and shyness, shy subjects were judged both by themselves and by peers to be lower in mental abilities. This relation was stronger for the state shyness measure (i.e. self-rating of shyness in the group context) than for the dispositional measure of shyness. Thus the specific behavior of the target in the group appeared to determine the evaluation of ability. Quantity of participation in the group discussion appeared to be the primary link between shyness and perceived intelligence, for both self and peer ratings. It is also possible that shy subjects' negative affect in the social situation prevented them from performing at their intellectual capacity and thus lower ratings could be an accurate reflection of performance in the specific situation. Self presentation strategies are another possible explanation.

Οι ποσότητες που χρησιμοποιήθηκαν για τη σύγκριση αντιστοιχούν στις μέσες ημερήσιες ολικές στήλες διοξειδίου του θείου για 44 επίγειους σταθμούς κατά την περίοδο 2004-2014. Η σύγκριση έχει τόσες πτυχές όσα και τα προϊόντα του οργάνου ΟΜΙ για το διοξείδιο του θείου. Τα συγκεκριμένα προϊόντα είναι τα PBL, TRL, TRM and STL αλλά το προϊόν που χρησιμοποιείται κυρίως είναι το PBL διότι βρίσκεται σε καλύτερη συμφωνία με τις επίγειες μετρήσεις. Αρχικά, οι χρονοσειρές του διοξειδίου του θείου για κάθε σταθμό εξετάστηκαν. Στη συνέχεια η έρευνα επικεντρώθηκε στη ηφαιστειακή δραστηριότητα της περιόδου μελέτης και οι ηφαιστειακές εκρήξεις που μελετήθηκαν ήταν Kasatochi (Αύγουστος 2008), Eyjafjallajokull (Μάιος 2010), Grimsvotn (Μάιος 2011), Nabro (Ιούνιος 2011) και Bardarbunga (Σεπτέμβριος 2014). Για κάθε ηφαιστειακή έκρηξη οι μηνιαίες χρονοσειρές (μήνας κατά τη διάρκεια του οποίου κάθε έκρηξη συνέβη) μελετήθηκαν. Τέλος, διαγράμματα διασποράς για κάθε ηφαιστειακή έκρηξη αναλύθηκαν προκειμένου να εξεταστούν οι τάσεις υποεκτίμησης ή υπερεκτίμησης του οργάνου ΟΜΙ.
description: In this master thesis, sulfur dioxide observations from OMI instrument onboard Aura satellite and relative ground-based Brewer spectrophotometer measurements were analyzed and examined in order to compare them. The quantities, used in the comparison, correspond to mean daily sulfur dioxide total columns for 44 stations during the decade 2004-2014. The comparison has as many aspects as the OMI sulfur dioxide products. These products are PBL, TRL, TRM and STL but mainly the PBL product is used because it has better agreement with the ground measurements. Firstly, the stations sulfur dioxide time series were examined. Afterwards the survey focused on the volcanic activity during the study period and the eruptive events examined were: Kasatochi (August 2008), Eyjafjallajokull (May 2010), Grimsvotn (May 2011), Nabro (June 2011) and Bardarbunga (September 2014). For each volcanic eruption the stations monthly time series (month during which the eruption had occurred) were examined. Finally, scatter diagrams for each volcanic eruption were analyzed in order to investigate OMI instrument underestimation or overestimation tendency.
Similar phenomena at different scales: Black Holes, the Sun, Gamma-ray Bursts, Supernovae, Galaxies and Galaxy Clusters

Publisher: name: arXiv
Year: 2007
Subjects: subject: Astrophysics (astro-ph)

description: Many similar phenomena occur in astrophysical systems with spatial and mass scales different by many orders of magnitudes. For examples, collimated outflows are produced from the Sun, proto-stellar systems, gamma-ray bursts, neutron star and black hole X-ray binaries, and supermassive black holes; various kinds of flares occur from the Sun, stellar coronae, X-ray binaries and active galactic nuclei; shocks and particle acceleration exist in supernova remnants, gamma-ray bursts, clusters of galaxies, etc. In this report I summarize briefly these phenomena and possible physical mechanisms responsible for them. I emphasize the importance of using the Sun as an astrophysical laboratory in studying these physical processes, especially the roles magnetic fields play in them; it is quite likely that magnetic activities dominate the fundamental physical processes in all of these systems. As a case study, I show that X-ray lightcurves from solar flares, black hole binaries and gamma-ray bursts exhibit a common scaling law of non-linear dynamical properties, over a dynamical range of several orders of magnitudes in intensities, implying that many basic X-ray emission nodes or elements are inter-connected over multi-scales. A future high timing and imaging resolution solar X-ray instrument, aimed at isolating and resolving the fundamental elements of solar X-ray lightcurves, may shed new lights onto the fundamental physical mechanisms, which are common in astrophysical systems with vastly different mass and spatial scales. Using the Sun as an astrophysical laboratory, "Applied Solar Astrophysics" will deepen our understanding of many important astrophysical problems.

Anomalous electronic structure of the positive muon in antimony : evidence for an isolated kondo impurity
Creators: name: Johnston, Thomas Michael Shaun
Publisher: name: University of British Columbia
Year: 2009

description: The anomalous electronic structure of a positive muon in the semimetal antimony wasinvestigated by the μSR (Muon Spin Rotation/Relaxation) technique. Precise measurements of the giant muon Knight shift (Kμ=+1.4%) were made as a function of temperature (2-20 K) and magnetic field (18-21 kG) with the applied magnetic field parallel to the c-axis of the antimony single crystal. No de Haas-van Alphen oscillations were observed at a temperature of 3 K, which indicates the electron spin density on the muon does not scale simply with the magnetic susceptibility of the conduction electrons. An upper limit of 0.2% of Kμ can be placed on the amplitude of the Kμ de Haas-van Alphen oscillations. The measured Kμ varies weakly with temperature below 10 K. The data were fit in three different ways. The best fit is to the form Kμ = 1/(a + bT² + cT4) with parameters a=7.167(3) x 10⁻³ b=6.4(7) x 1O⁻⁷K⁻²,and c=1.8(2) x 10⁻¹⁰K⁻⁴. A fit to an Arrhenius Law of the form 1— Ae^(Ea/kBT) yields a pre-exponential of 0.47(4) and an activation temperature Ea/kB of 40(2) K. If one fits to an expression for the Kondo susceptibility of the form Kμ = a(1/2πTK — 0.433T²/T³k) at low temperatures (2-10 K) one obtains a parameter a=14.0(0.3) K and a Kondo temperature TK=160(3) K. Together with existing measurements of Kμ at higher temperatures (90-180 K) we ob serve a crossover from a weakly temperature dependent Pauli paramagnetic behaviour below 10 K to a Curie-like behaviour above 90 K. This crossover is characteristic of a Kondo impurity indicating the anomalous electronic structure of a positive muon in antimony may be due to muonium formation, in which a local moment is centered on or near the muon. Within context of this model estimates of the hyperfine parameters (A=259.7(4) MHz and A±=129.9(2) MHz) for muonium in antimony are similar to those for Mu* in covalent semiconductor. The large anisotropy suggests a large spin density resides on the nearest neighbour antimony atom(s). Since the μSR technique only permits one muon in the sample at a time, the anomalous electronic structure of a muon in antimony may be a unique example of a truly isolated Kondo impurity in so far as other magnetic impurities in the sample can be neglected. A large Korringa-like relaxation of the muon in antimony was observed in longitudinal field implying the spin dynamics of a muon in antimony are also anomalous when compared to normal metals. The Korringa constant S/(K² μ T₁T) is temperature independent as expected for a Kondo impurity for T << TK. Above a temperature of 100 K, which is comparable to TK, a breakdown of the Korringa law is seen. In particular a peak in T₁⁻¹ at a temperature of 75 K is observed.

description: Τhis diploma thesis exposes the full adder circuit using a memristor crossbar structure. The term "memristor" comes from the combination of the terms "memory" and "resistor" and is a passive element that can change its resistance depending on the value and the direction of current that passes through it. Every memristor has at the same time a highly calculating dynamic and a capacity of memorizing in a nanoscale level. This element -with the help of crossbar structures- is being used as a switch in order to implement the full adder circuit. The first chapter describes memristor’s operation and simulations of it -by using Vteam model- in order to be better understood by the readers. The second chapter describes the magic logic which has been used to design gateways –some of them can be incorporated within a crossbar-. The third chapter exposes in detail the process of registering and reading of a crossbar. It also contains the design of full adder’s circuit. The last chapter refers to an algorithm that implements a full adder using magic gates and can be incorporated- in an appropriate way- within a conventional memory.

description: Η αξιοποίηση του memristor (αντίσταση με μνήμη), μιας ιδέας που είχε προταθεί σε θεωρητικό επίπεδο πριν από 40 χρόνια, δείχνει τώρα να έρχεται πιο κοντά στην εμπορική αξιοποίηση. To memristor, ένα πρωτοποριακό τσιπ μνήμης λειτουργεί ταχύτερα, αποδοτικότερα και το κυριότερο, χωρίς να σβήνει όταν κλείνει το ρεύμα. Συνιστά το τέταρτο θεμελιώδες δομικό στοιχείο των ηλεκτρονικών κυκλωμάτων έπειτα από τον πυκνωτή, την αντίσταση και τον επαγωγέα. Τα τελευταία χρόνια η αξιοποίηση του memristor σε κυκλωματικές διατάξεις αποτελεί στόχο των ερευνητών. Αντικείμενο της εργασίας αυτής είναι η δημιουργία κυκλωμάτων που θα αξιοποιήσουν όχι τόσο την ιδιότητα μνήμης των memristor αλλά την ικανότητα τους να μεταβάλλουν την αντίσταση τους μεταξύ δύο καταστάσεων. Οι καταστάσεις αυτές προσαρμόζονται σύμφωνα με τα εκάστοτε σήματα εισόδου, δίνοντας έτσι τη δυνατότητα υλοποίησης ψηφιακών λογικών πυλών και κυκλωμάτων. Στην παρούσα εργασία, υλοποιήθηκαν οι βασικές λογικές πύλες με σκοπό την οργάνωση τους σε μία δομή για την παραγωγή ενός κυκλώματος full adder. Τέλος, το κύκλωμα αυτό συγκρίνεται με μία δομή full adder με cmos για την αξιολόγηση της κυκλωματικής δομής που υλοποιήθηκε με memristor.
description: The usage of memristor (resistance with memory), an idea that was proposed theoretically 40 years ago, is now getting closer to commercial production. Memristor is a pioneer memory chip which works faster and better, but the most important feature is that it doesn’t shut down when there is no electricity. It is the fourth basic fundamental element of circuits after capacitor, resistor and conductor. During the last years more and more researchers has set a goal to use memristor in circuits. The objective purpose of this thesis is to create circuits which will be able to use the capability of the memristor to alternate the resistance between two states. These states can be alternated in proportion of the inputs giving the chance of creating digital logic gates and circuits. In this thesis were made basic logic gates with the purpose of combining them to make a full adder circuit. Finally, this circuit is being compared with another full adder circuit which is made in cmos logic to give us a better review.

description: High-transition-temperature (high-Tc) superconductivity develops near antiferromagnetic phases, and it is possible that magnetic excitations contribute to the superconducting pairing mechanism. To assess the role of antiferromagnetism, it is essential to understand the doping and temperature dependence of the two-dimensional antiferromagnetic spin correlations. The phase diagram is asymmetric with respect to electron and hole doping, and for the comparatively less-studied electron-doped materials, the antiferromagnetic phase extends much further with doping [1, 2] and appears to overlap with the superconducting phase. The archetypical electron-doped compound Nd{2-x}Ce{x}CuO{4\pmδ} (NCCO) shows bulk superconductivity above x \approx 0.13 [3, 4], while evidence for antiferromagnetic order has been found up to x \approx 0.17 [2, 5, 6]. Here we report inelastic magnetic neutron-scattering measurements that point to the distinct possibility that genuine long-range antiferromagnetism and superconductivity do not coexist. The data reveal a magnetic quantum critical point where superconductivity first appears, consistent with an exotic quantum phase transition between the two phases [7]. We also demonstrate that the pseudogap phenomenon in the electron-doped materials, which is associated with pronounced charge anomalies [8-11], arises from a build-up of spin correlations, in agreement with recent theoretical proposals [12, 13].

description: The discovery of optical jets immersed in the strong UV radiation field of the Rosette Nebula sheds new light on, but meanwhile poses challenges to, the study of externally irradiated jets. The jet systems in the Rosette are found to have a high state of ionization and show unique features. In this paper, we investigate the evolutionary status of the jet driving sources for young solar-like stars. To our surprise, these jet sources indicate unexpected near infrared properties with no excess emission. They are bathed in harsh external UV radiation such that evaporation leads to a fast dissipation of their circumstellar material. This could represent a transient phase of evolution of young solar-like stars between classical and weak lined T Tauri stars. Naked T Tauri stars formed in this way have indistinguishable evolutionary ages from those of classical T Tauri stars resulting from the same episode of star formation. However, it would be hard for such sources to be identified if they are not driving an irradiated jet in a photoionized medium.

description: Τα παιδιά με δυσκολίες στην κινητική μάθηση συναντούν εμπόδια στην κατάκτηση και εκτέλεση των αντιληπτικο-κινητικών δεξιοτήτων. Σχετικές μελέτες έχουν αναδείξει τη συνύπαρξη αυτών των διαταραχών με μαθησιακές δυσκολίες. Η έρευνα αυτή εξετάζει τη συχνότητα εμφάνισης των δυσκολιών στην κινητική μάθηση, καθώς και την πιθανότητα συνύπαρξης των δυσκολιών αυτών με προβλήματα στη συμπεριφορά και στο λόγο. Για το σκοπό αυτό, διενεργήθηκε σύγκριση μεταξύ παιδιών προσχολικής ηλικίας με και χωρίς τις εν λόγω δυσκολίες. Τα αποτελέσματα έδειξαν πως τα παιδιά με δυσκολίες εμφάνισαν υψηλότερα ποσοστά στη συχνότητα εμφάνισης των δυσκολιών σε σχέση με τα παιδιά χωρίς δυσκολίες. Επίσης, βρέθηκε μεγάλο ποσοστό συχνότητας συνύπαρξης δυσκολιών στη λεπτή κινητικότητα, και κυρίως στις δεξιότητες γραφής, με προβλήματα στη συμπεριφορά και στο λόγο. Συμπερασματικά, οι δυσκολίες αυτές υποθάλπουν αντιληπτικο-κινητικές δυσλειτουργίες, που μπορούν να προβλέψουν μαθησιακές δυσκολίες στην κατάκτηση όχι μόνο της γραφής, αλλά και σε άλλους τομείς της μάθησης.
description: Children with motor disorders have difficulties in learning and performing perceptual-motor skills. Research has found comorbidity of motor disorders and learning difficulties. This study examined the existence frequency of motor disorders and the comorbidity with language and behavior difficulties. For this purpose, we compared preschool children with and without difficulties. The results showed that the group with difficulties performed higher rates of difficulties compared to children without difficulties. Also, great comorbidity frequency rate in fine motor difficulties was found, especially in writing ability, with language impairment and behavioral problems. In conclusion, these difficulties underlie perceptual-motor dysfunctions that could predict learning difficulties in writing and in other areas of learning.

description: It is presented a critical review that encompasses the new approaches in the perception and interpretation of the gamma-glutamyl cycle. Literature data are consistent with the hypothesis that it plays an important role in glutathione homeostasis in the cell, fulfilling and the requirements of an amino acid transport system. Despite this, a rethink of the cycle has never been undertaken, and this fact has led to the perpetuation of similar errors.

description: In this paper a general approach to reconstruct three dimensional field solutions in particle accelerator magnets from distributed magnetic measurements is presented. To exploit the locality of the measurement operation a special discretization of the Laplace equation is used. Extracting the coefficients of the field representations yields an inverse problem which is solved by Bayesian inversion. This allows not only to pave the way for uncertainty quantification, but also to derive a suitable regularization. The approach is applied to rotating coil measurements and can be extended to any other measurement procedure.

description: In the framework of the Gross-Pitaevskii mean field approach it is shown that the supersonic flow of a Bose-Einstein condensate can support a new type of pattern--an oblique dark soliton. The corresponding exact solution of the Gross-Pitaevskii equation is obtained. It is demonstrated by numerical simulations that oblique solitons can be generated by an obstacle inserted into the flow.

description: The article examines new approaches to providing psychotherapeutic assistance to adolescents with type 1 diabetes. At the initial stage, adolescents were tested for emotional changes using psychometric scales. During the study of the psycho-emotional background, 96.6% of the examined adolescents showed signs of depressive disorder of the neurotic register. Various types of active group work were used to conduct psychological and pedagogical assistance: functional training for the development of skills and self-confidence, communication training, music therapy, body-oriented and dance-movement therapy, cognitive training. All adolescents who received combined integrative psychological and pedagogical help in the surveyed group showed an improvement in their general condition, emotional background, and intra-family relationships.

Mechanobiology of shear-induced platelet aggregation leading to occlusive arterial thrombosis: a multiscale in silico analysis

description: Occlusive thrombosis in arteries causes heart attacks and strokes. The rapid growth of thrombus at elevated shear rates (~10,000 1/s) relies on shear-induced platelet aggregation (SIPA) thought to come about from the entanglement of von Willebrand factor (VWF) molecules. The mechanism for SIPA is not yet understood in terms of cell- and molecule-level dynamics in fast-flowing bloodstreams. Towards this end, we develop a multiscale computational model to recreate SIPA in silico, where the suspension dynamics and interactions of individual platelets and VWF multimers are resolved directly. The platelet-VWF interaction via GP1b-A1 bonds is prescribed with intrinsic binding rates theoretically derived and informed by single-molecule measurements. The model is validated against existing microfluidic SIPA experiments, showing good agreement with the in vitro observations in terms of the morphology, traveling distance, and capture time of the platelet aggregates. Particularly, the capture of aggregates can occur in a few milliseconds, comparable to the platelet transit time through pathologic arterial stenotic sections and much shorter than the time for shear-induced platelet activation. The multiscale SIPA simulator provides a cross-scale tool for exploring the biophysical mechanisms of SIPA in silico that are difficult to access with single-molecule measurements or micro-/macro-fluidic assays only.

description: The aim of the present thesis is the study, characterization and evaluation of artificial aged and overaged composite materials aluminum alloy matrix 2024 reinforced with particulate silicon carbide (SiCp) of about 40 μm in size after natural aging of more than 15 years. The composite materials tested in this work are aluminum alloy matrix 2024 with a volume fraction of 0, 8, 14, 19 and 24 in SiCp. The composites were manufactured by stir- casting in the semi- solid state of the alloy AA2024. For comparison reasons unreinforced AA2024 alloy has been manufactured as well. After manufacturing all materials, reinforced and unreinforced, were artificially aged at 177 C for periods of 14 and 100 hours. Furthermore, all materials were naturally aged for more than 15 years. To achieve the aim of the thesis microhardness measurements using Vickers method were occurred in matrix alloy as well metallographic testing in all materials.
PHYSICAL FEATURES OF BRANCHED CIRCUITS WITH CONTACT POTENTIAL DIFFERENCES. (NEW ABOUT BIPOLAR TRANSISIOR)
Creators: name: Parthentiev, N.
name: Partfenteva, N.
Publisher: name: Sciences of Europe
Year: 2021
Subjects: branched chain
contact phenomena
bipolar transistor.

description: Conditions are formulated under which the contact differences of potentials in a branched chain can be neglected. 1) A relatively small current value at which the Peltier and Zeeman effects can be neglected. 2) Constant current in all elements of loop current. 3) The constancy of the energy spectrum of current carriers. A detailed analysis of contact phenomena in a bipolar transistor is carried out. It is shown that an abrupt increase in the input voltage upon the appearance of a collector voltage is associated with disturbances in the energy balance, when the electron energy spent on the metal-emitter barrier transition cannot be compensated for in the base-metal transition. The balance is disturbed due to the different energy spectra of electrons in the transitions of the transistor. The conventional interpretation of this phenomenon, which assumes feedback between collector and input voltage, is erroneous. The adopted concept, together with the constructive solution of the semiconductor device, the properties of the metals used to actually connect the transistors. Development of this concept to build more accurate transistor models, free from errors associated with inaccurate physical representation of the operation of the transistor.
The comprehension of the relational terms because and so by preschool children
Creators: name: Welsh, Elizabeth Therese
Publisher: name: University of British Columbia
Year: 2009

description: The comprehension of the relational terms because and so was investigated in preschoolers aged 3;3 - 5;8. The children were told short stories and then were asked to complete sentences that dealt with story content and contained these words. The experiment was designed to see whether age, familiarity with story content, the use of pictures, or the particular term (because vs. so) would affect children’s answers. The results indicated that increasing age and familiarity of story content significantly improved performance. Three year olds provided correct answers only for the stories with familiar content, while five year olds were beginning to succeed even when the story content was new. There was also evidence that pictorial cues had a different effect for the two different relational terms, and that pictorial cues interacted with content familiarity in a characteristic manner at different ages. Findings from this st.udy provide support for a model of lexical development in which the first uses of relational terms are context dependent. This could indicate that early lexical representations are incomplete or that the processing of complex sentential relationships can exceed children’ s attentional resources.

description: To survive a learning management system (LMS) implementation an understanding of the needs of the various stakeholders is necessary. The goal of every LMS implementation is to ensure the use of the system by instructors and students to enhance teaching and communication thereby enhancing learning outcomes of the students. If the teachers and students do not use the system, the system is useless. This research is motivated by the importance of identifying and understanding various stakeholders involved in the LMS implementation process in order to anticipate possible challenges and identify critical success factors essential for the effective implementation and adoption of a new LMS system. To this end, we define the term stakeholder. We conducted a stakeholder analysis to identify the key stakeholders in an LMS implementation process. We then analyze their goals and needs, and how they collaborate in the implementation process. The findings of this work will provide institutions of higher learning an overview of the implementation process and useful insights into the needs of the stakeholders, which will in turn ensure an increase in the level of success achieved when implementing a LMS.
