description: Abstract: Quality control consists of several multifaceted responsibilities and roles that are critical in measuring and testing to determine product quality. It requires statistical data to be recorded during the production process. Quality control uses specific research tools to accomplish fact-finding processes and conduct analyses. It is the role of a quality control professional to analyse these measures against some standards put in place to determine the quality of products. The standards depend on the quality management department, company policies, and industrial regulatory bodies. Based on this evidence-gathering, the quality control department will recommend changes. The role of administrators and managers in industries is to monitor the performance of employees effectively to ensure they are completing tasks according to company procedures. The department reviews data to identify and resolve risks to the organisation's quality standards. To provide training to employees on quality assurance principles and practices. The role of a quality assurance administrator is to create the documentation for the quality processes of an organisation. Their job is to collect and analyse data and create metrics to measure the results and efficiency of quality assurance procedures. With the rise of global competitiveness and the growing need for higher education institutions to meet international standards, QA frameworks have become essential. In developing countries, however, challenges arise from resource constraints, limited employee engagement, and often unstructured governance. The existing studies reveal that cognitive information is lacking hence there is a situation where university employees fail to significantly identify the roles of quality assurance directors in Ugandan universities. The findings contribute to improving higher education institutions' internal processes, policy formulation, and employee empowerment strategies, ensuring sustainable quality outcomes. This article further aims to share the roles and importance of the directorate of quality assurance in universities and other organisations.

description: The optical and UV variability of the majority of AGN may be related to the reprocessing of rapidly-changing X-ray emission from a more compact region near the central black hole. Such a reprocessing model would be characterised by lags between X-ray and optical/UV emission due to differences in light travel time. Observationally however, such lag features have been difficult to detect due to gaps in the lightcurves introduced through factors such as source visibility or limited telescope time. In this work, Gaussian process regression is employed to interpolate the gaps in the Swift X-ray and UV lightcurves of the narrow-line Seyfert 1 galaxy Mrk 335. In a simulation study of five commonly-employed analytic Gaussian process kernels, we conclude that the Matern 1/2 and rational quadratic kernels yield the most well-specified models for the X-ray and UVW2 bands of Mrk 335. In analysing the structure functions of the Gaussian process lightcurves, we obtain a broken power law with a break point at 125 days in the UVW2 band. In the X-ray band, the structure function of the Gaussian process lightcurve is consistent with a power law in the case of the rational quadratic kernel whilst a broken power law with a breakpoint at 66 days is obtained from the Matern 1/2 kernel. The subsequent cross-correlation analysis is consistent with previous studies and furthermore, shows tentative evidence for a broad X-ray-UV lag feature of up to 30 days in the lag-frequency spectrum where the significance of the lag depends on the choice of Gaussian process kernel.

description: The aim of the diploma thesis is to study the technologies of solar energy utilization. Initially the phenomenon of environmental pollution, the types of gaseous pollutants, the impacts they caused, and the different forms of renewable energy sources were examined. Solar energy was then analyzed, starting with its historical evolution, its use and exploitation in modern times and particularly in the domestic environment. At the same time, an explanation is given of the Greek investment environment, the possibilities of new investments in combination with the town planning, spatial and environmental conditions for the installation of photovoltaic systems. In addition, China's photovoltaic market, the European market and forecasts for the upcoming two years have been presented with particular emphasis on the role of solar energy in the European electricity system as well as the prospects for the development of this sector in a global level. Lastly, special reference was made to photovoltaic tariffs, presenting the advantages and disadvantages of different policies, while the different payment structures with particular emphasis on the fixed - price and premium - price models were analyzed

description: The work fluctuations of a harmonic oscillator in contact with a thermostat and driven out of equilibrium by an external force are studied experimentally. For the work both the transient and stationary state fluctuation theorems hold. The finite time corrections are very different from those of a first order Langevin equation. The heat and work fluctuations are studied when a periodic forcing is applied to the oscillator. The importance of the choice of the ''good work'' to compute the free energy from the Jarzinsky equality is discussed.

description: Submilliarcsecond astrometry and imaging of the black hole Sgr A* at the Galactic Center may become possible in the near future at infrared and submillimetre wavelengths. This resolution is sufficient to observe the silhouette the supermassive black hole in the Galactic center casts upon background emission. However, more exciting is the prospect of observing ``hot spots'' in the accretion flow. Here we discuss how such measurements may be used to test not only the consistency of General Relativity, but also the validity of the Kerr metric in particular.

description: Link prediction is a fundamental challenge in network science. Among various methods, similarity-based algorithms are popular for their simplicity, interpretability, high efficiency and good performance. In this paper, we show that the most elementary local similarity index Common Neighbor (CN) can be linearly decomposed by eigenvectors of the adjacency matrix of the target network, with each eigenvector's contribution being proportional to the square of the corresponding eigenvalue. As in many real networks, there is a huge gap between the largest eigenvalue and the second largest eigenvalue, the CN index is thus dominated by the leading eigenvector and much useful information contained in other eigenvectors may be overlooked. Accordingly, we propose a parameter-free algorithm that ensures the contributions of the leading eigenvector and the secondary eigenvector the same. Extensive experiments on real networks demonstrate that the prediction performance of the proposed algorithm is remarkably better than well-performed local similarity indices in the literature. A further proposed algorithm that can adjust the contribution of leading eigenvector shows the superiority over state-of-the-art algorithms with tunable parameters for its competitive accuracy and lower computational complexity.

description: The time-reversal symmetry of nonequilibrium fluctuations is experimentally investigated in two out-of-equilibrium systems namely, a Brownian particle in a trap moving at constant speed and an electric circuit with an imposed mean current. The dynamical randomness of their nonequilibrium fluctuations is characterized in terms of the standard and time-reversed entropies per unit time of dynamical systems theory. We present experimental results showing that their difference equals the thermodynamic entropy production in units of Boltzmann's constant.

description: We report tunable crossed Andreev reflection (CAR) in a superconductor sandwiched between two antiferromagnetic layers. We consider recent examples of two-dimensional magnets with hexagonal lattices, where gate voltages control the carrier type and density, and predict a robust signature of perfect CAR in the nonlocal differential conductance with one electron-doped and one hole-doped antiferromagnetic lead. The magnetic field-free and spin-degenerate CAR signal is electrically controlled and visible over a large voltage range, showing promise for solid-state quantum entanglement applications.

description: Nel 1985, affidando alle pagine delle Lezioni americane il suo 'testamento spirituale', Italo Calvino indicava nella leggerezza il tratto più caratteristico della propria avventura di scrittore. Partiva così un affascinante viaggio in cerca di esempi emblematici di levita, che da Ovidio e Lucrezio portava a Montale e Kundera passando per Cavalcanti, Shakespeare, Leopardi, Kafka... Il grande assente della rassegna calviniana è Friedrich Nietzsche; eppure il filosofo aveva a lungo riflettuto sulla leggerezza e ne aveva esaltato le qualità. Dal confronto tra l’idea nietzschiana di leggerezza e quella calviniana, emergono due visioni antitetiche e speculari; esse rappresentano i poli estremi di un discorso che va idealmente dal 1885 di Cos parl̀ Zarathustra, al 1985 delle Lezioni americane e prosegue fino ai nostri giorni, assumendo sfumature sempre differenti, ma muovendosi comunque all’interno del perimetro segnato da Nietzsche e Calvino, come dimostrano gli esempi qui analizzati di Antonio Moresco e Daniele Del Giudice.

description: Context: For the past 3 years we have been monitoring a sample of 62 K giant stars using precise stellar radial velocity measurements taken at the Thueringer Landessternwarte Tautenburg. Aims: To search for sub-stellar companions to giant stars and to understand the nature of the diverse radial velocity variations exhibited by K giant stars. Methods: We present precise stellar radial velocity measurements of the K1III giant star 4 UMa (HD 73108). These were obtained using the coude echelle spectrograph of 2-m Alfred Jensch Telescope. The wavelength reference for the radial velocity measurements was provided by an iodine absorption cell. Results: Our measurements reveal that the radial velocity of 4 UMa exhibits a periodic variation of 269.3 days with a semiamplitude K = 216.8 m/s. A Keplerian orbit with an eccentricity, e = 0.43 +/- 0.02 is the most reasonable explanation for the radial velocity variations. The orbit yields a mass function, f(m) = (2.05 +/- 0.24) x 10^(- 7) M_sun. From our high resolution spectra we calculate a metallicity of -0.25 +/- 0.05 and derive a stellar mass of 1.23 M_sun +/- 0.15 for the host star. Conclusions: The K giant star 4 UMa hosts a substellar companion with minimum mass m sin i = 7.1 +/- 1.6 M_Jupiter.

Description of spin transport and precession in spin-orbit coupling systems and a general equation of continuity

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: By generalizing the usual current density to a matrix with respect to spin variables, a general equation of continuity satisfied by the density matrix and current density matrix has been derived. This equation holds in arbitrary spin-orbit coupling systems as long as its Hamiltonian can be expressed in terms of a power series in momentum. Thereby, the expressions of the current density matrix and a torque density matrix are obtained. The current density matrix completely describes both the usual current and spin current as well; while the torque density matrix describes the spin precession caused by a total effective magnetic field, which may include a realistic and an effective one due to the spin-orbit coupling. In contrast to the conventional definition of spin current, this expression contains an additional term if the Hamiltonian includes nonlinear spin-orbit couplings. Moreover, if the degree of the full Hamiltonian $\geq3$, then the particle current must also be modified in order to satisfy the local conservation law of number.

description: Current analyses of VLT/UVES quasar spectra disagree with the Keck/HIRES evidence for a varying fine-structure constant, alpha. To investigate this we introduce a simple method for calculating the minimum possible uncertainty on Delta(alpha)/alpha for a given quasar absorber. For many absorbers in Chand et al. (2004) and for the single-absorber constraint of Levshakov et al. (2006) the quoted uncertainties are smaller than the minimum allowed by the UVES data. Failure of this basic consistency test prevents reliable comparison of the UVES and HIRES results.

description: The goal of this paper is to increase the membership list of the Chamaeleon star forming region and the $ε$ Cha moving group, in particular for low-mass stars and substellar objects. We extended the search region significantly beyond the dark clouds. Our sample has been selected based on proper motions and colours obtained from Gaia and 2MASS. We present and discuss the optical spectroscopic follow-up of 18 low-mass stellar objects in Cha I and $ε$ Cha. We characterize the properties of objects by deriving their physical parameters, both from spectroscopy and photometry. We add three more low-mass members to the list of Cha I, and increase the census of known $ε$ Cha members by more than 40%, confirming spectroscopically 13 new members and relying on X-ray emission as youth indicator for 2 more. In most cases the best-fitting spectral template is from objects in the TW Hya association, indicating that $ε$ Cha has a similar age. The first estimate of the slope of the initial mass function in $ε$ Cha down to the sub-stellar regime is consistent with that of other young clusters. We estimate our IMF to be complete down to $\approx 0.03$M$_{\odot}$. The IMF can be represented by two power laws: for M $$ 0.5 M$_{\odot}$ $α= 1.44 \pm 0.12$. We find similarities between $ε$ Cha and the southernmost part of Lower Centaurus Crux (LCC A0), both lying at similar distances and sharing the same proper motions. This suggests that $ε$ Cha and LCC A0 may have been born during the same star formation event

A measurement of the strong coupling constant using two jet event rates at 91 Gev
Creators: name: Jones, Matthew
Publisher: name: University of British Columbia
Year: 2009

description: An analysis of hadronic Z° decays observed in the OPAL detector at LEP is presented. The analysis involves the selection of hadronic Z° decays from the set of OPAL data and the selection of well resolved charged tracks and electromagnetic energy clusters observed in each event. These are then used to determine the relative rates of events with 2-, 3-, 4- and 5-jets using a number of different jet definition schemes. These rates are then compared with theoretical predictions, computed perturbatively to second order in the coupling constant as using the theory of Quantum Chromodynamics. By fitting the theoretical predictions to the data, the QCD parameters Λ and µ are determined and a value of the strong coupling constant is obtained for each jet definition scheme. In the analysis, the experimental uncertainties in the measured n-jet event rate distributions are estimated. A particular emphasis is placed on the description of the techniques used to correct the measured distributions for the limited acceptance and response of the detector and for the unknown process of hadronization. The applicability of the corrections for detector acceptance and response are justified and an examination of the uncertainties in the measured values of αs due to the unknown level of virtuality of the primary partons is presented. It is found that the measured values of αs are consisted with other measurements made at LEP energies and that the values determined in each jet definition scheme are consistent with each other.

description: The aim of this diploma thesis was the evaluation, synthesis and presentation of data on the safety and efficacy of the drug eltrombopag in children and adults with immune thrombocytopenia (ITP). This was made possible through a systematic and in-depth review of the online and gray literature, finding the most appropriate studies for qualitative synthesis and finally statistical data synthesis from the individual studies. We concluded after our search seven randomized and double blind studies that were included in our qualitative and quantitative-statistical synthesis. Using tables and diagrams, we presented that the drug eltrombopag is safe and effective in immune thrombocytopenia in children and adults. However, more studies are needed, with a larger sample of patients on the efficacy of the drug, and more studies that compare eltrombopag with other therapeutic regimens

description: For a long time, investigation into the weak interactions of quarks has guided us toward understanding the Standard Model we know today. Now in the era of high precision, these studies are still one of the most promising avenues for peering beyond the Standard Model. This is a large-scale endeavour with many tales and many protagonists. In these pages I follow a few threads of a complex story, those passing through the realm of lattice gauge theory.

description: Το παρόν πόνημα εξετάζει κυρίως τη ζωή, τη δράση και το μαρτύριο του μητροπολίτου Κορυτσάς Φωτίου. Επιπλέον εξετάζει πολλές πτυχές και πολλά πρόσωπα (εν συντομία) του Μακεδονικού Αγώνα. Στο πρώτο μέρος εξετάζουμε την γενικότερη κατάσταση που επικρατούσε στην Κορυτσά επί ποιμαντορίας του Φωτίου Καλπίδη. Επιπλέον αναφερόμαστε στις διάφορες εθνικιστικές προπαγάνδες που ελάμβαναν χώρα στην ευρύτερη περιοχή και που είχαν στόχο να πλήξουν τον Μητροπολίτη Φώτιο και τον ελληνισμό γενικότερα. Στο δεύτερο μέρος αναφερόμαστε στο γεγονός της έναρξης του Μακεδονικού αγώνα το 1904 και ειδικότερα στον αγώνα που διεξαγόταν στην περιοχή της Κορυτσάς. Στο τρίτο μέρος ασχολούμαστε με τον βίο και την πολιτεία του Φωτίου. Στο τέταρτο και τελευταίο μέρος αναλύουμε κυρίως, τα τραγικά γεγονότα που συνέβησαν στο Μητροπολίτη το έτος 1906, δηλαδή στον λιθοβολισμό του και στην δολοφονία του
description: This essay deals mainly with the life, action and martyrdom of the metropolitan Korytsas Photios. It also examines many aspects and many faces (briefly) of the Macedonian Struggle. In the first part we examine the general situation prevailing in Koritsa on the pastoral work of Photios Kalpides. We also refer to the various nationalist propaganda that took place in the wider region and which were intended to attack Metropolitan Photios and Hellenism in general. In the second part we refer to the fact of the beginning of the Macedonian struggle in 1904 and especially to the struggle that took place in the region of Korytsa. In the third part we deal with the life and the state of Photios. In the fourth and final part we mainly analyze the tragic events that happened to the Metropolitan in 1906, namely his stoning and murder

description: In this paper we study the description of the Universe based on the low energy superstring theory modified by the Loop Quantum Gravity effects.This approach was proposed by De Risi et al. in the Phys. Rev. D {\bf 76} (2007) 103531. We show that in the contrast with the string motivated pre-Big Bang scenario, the cosmological realisation of the $t$-duality transformation is not necessary to avoid an initial singularity. In the model considered the universe starts its evolution in the vacuum phase at time $t\to - \infty$. In this phase the scale factor $a\to 0$, energy density $ρ\to 0$ and coupling of the interactions $g^2_s \to 0$. After this stage the universe evolves to the non-singular hot Big Bang phase $ρ\to ρ_{\text{max}} < \infty$. Then the standard classical universe emerges. During the whole evolution the scale factor increases monotonically. We solve this model analytically. We also propose and solve numerically the model with an additional dilaton potential in which the universe starts the evolution from the asymptotically free vacuum phase $g^2_s \to 0$ and then evolves non-singularly to the emerging dark energy dominated phase with the saturated coupling constant $g^2_s \to \text{const}$.

description: Το αντικείμενο αυτής της Μεταπτυχιακής Διπλωματικής Εργασίας είναι η σχεδίαση δικτυακών ασκήσεων με τον προσομοιωτή δικτύων GNS3 To GNS3 μπορεί να εξομοιώσει πραγματικό δικτυακό software χάρη στο Dynamips, ένα software ειδικό να εξομοιώνει images από Routers της Cisco. Σημαντικό ρόλο επίσης στο GNS3 παίζει η υποστήριξη του για virtual machines και το QEmu, έτσι ώστε να μπορούμε να προσομοιώσουμε Linux PC, Windows XP PC, routers της Juniper, Cisco VIRL images και διάφορα άλλα. Το GNS3 δεν έχει προ εγκατεστημένα images από κανένα εξάρτημα, οπότε είναι δική μας ευθύνη να βρούμε. Κατέχοντας τις βασικές γνώσεις περί δικτύων κι έχοντας παραμετροποιήσει κατάλληλά το GNS3 προβαίνουμε στην μελέτη 10 ασκήσεων. Οι ασκήσεις αυτές είναι: Subnetting και Βασικό Configuration, Layer 2 VLAN, Inter VLAN Routing, Στατικό και Δυναμικό Routing, OSPF Routing, EIGRP Routing, DHCP, Access Control Lists, HSRP και NAT. Ασκήσεις οι οποίες είναι ικανές να καλύψουν ένα μεγάλο μέρος της ύλης του CCNA
description: The purpose of this Master Thesis is to design networking courses using the GNS3 networking simulator. GNS3 can emulate real networking software using Dynamips, a software specially designed for running Cisco router images. An important feature of GNS3 is the support for virtual machines and QEmu, so that we can simulate Linux PC, Windows XP PC, Juniper routers, Cisco VIRL images and much more. GNS3 has no preinstalled images for any components, so it is our responsibility to obtain them. Mastering the basic networking elements and having configured the GNS3 properly, we proceed to study 10 networking courses. These courses are: Subnetting and Basic Configuration, Layer 2 VLAN, Inter VLAN Routing, Static and Dynamic Routing, OSPF Routing, EIGRP Routing, DHCP, Access Control Lists, HSRP and NAT. Such courses are enough to cover an essentially large part of the CCNA study

description: Classical scaling relationships for rheological quantities such as the $μ(J)$-rheology have become increasingly popular for closures of two-phase flow modeling. However, these frameworks have been derived for monodisperse particles. We aim to extend these considerations to sediment transport modeling by using a more realistic sediment composition. We investigate the rheological behavior of sheared sediment beds composed of polydisperse spherical particles in a laminar Couette-type shear flow. The sediment beds consist of particles with a diameter size ratio of up to ten, which corresponds to grains ranging from fine to coarse sand. The data was generated using fully coupled, grain resolved direct numerical simulations using a combined lattice Boltzmann - discrete element method. These highly-resolved data yield detailed depth-resolved profiles of the relevant physical quantities that determine the rheology, i.e., the local shear rate of the fluid, particle volume fraction, total shear, and granular pressure. A comparison against experimental data shows excellent agreement for the monodisperse case. We improve upon the parameterization of the $μ(J)$-rheology by expressing its empirically derived parameters as a function of the maximum particle volume fraction. Furthermore, we extend these considerations by exploring the creeping regime for viscous numbers much lower than used by previous studies to calibrate these correlations. Considering the low viscous numbers of our data, we found that the friction coefficient governing the quasi-static state in the creeping regime tends to a finite value for vanishing shear, which decreases the critical friction coefficient by a factor of three for all cases investigated.
Adaptation of responses to prolonged stimulation in single neurons in area 17 of the cat
Creators: name: Marlin, Stuart Graham
Publisher: name: University of British Columbia
Year: 2008

description: The locus and mechanisms of adaptation of neurons in Area 17 of the cat were investigated with extracellular unit recording techniques. Following prolonged visual stimulation, the responses of cells in Area 17 were reduced. The adaptation-induced changes in the responsivity of neurons could be restricted to small regions of the cell's receptive field and could show adaptation effects which spread asymmetrically across the receptive field. Prolonged unidirectional motion resulted in changes in the excitatory and inhibitory interactions between receptive field positions. These changes are thought to underlie the adaptation-induced changes in direction selectivity in cortical cells. The adaptation was not reduced by pharmacological agents which block the inhibitory neurotransmitter gamma-aminobutyric acid. Neurons in the lateral geniculate nucleus did not show adaptation at rates of stimulation which were optimal for inducing adaptation in cortical neurons. These experiments demonstrate that the adaptation of responses observed in visual cortical cells is not due to a general process which affects the responsivity of the cell, nor is adaptation the product of a GABAergic inhibitory input onto the cell. Rather adaptation must be a process occuring locally in either the pre or postsynaptic terminal or distal dendrites.

description: We present deep Hubble Space Telescope Advanced Camera for Surveys / High Resolution Channel U, narrow-V, and I images of nine "ultracompact" blue dwarf galaxies (UCBDs) selected from the Sloan Digital Sky Survey. We define UCBDs as local (z < 0.01) star-forming galaxies having angular diameters < 6" and physical sizes < 1 kpc. They are also among the most metal-poor galaxies known, and are found to reside within voids. Both the HST images and the objects' optical spectra reveal that they are composites of young (~1 Myr) populations that dominate their light, and older (~10 Gyr) populations that dominate their stellar masses, which we estimate to be ~10^7 - 10^8 Msol. An intermediate-age population is also indicated in most cases. The objects are not as dynamically disturbed as the prototype UCBD, POX 186, but the structure of several of them suggests that their current starbursts have been triggered by the collisions/mergers of smaller clumps of stars. In one case, HS 0822+3542, the ACS/HRC images resolve the object into two small (~100 pc) components which appear to have recently collided, supporting this interpretation. In six of the objects much of their star formation is concentrated in Young Massive Star clusters. The evidence that the galaxies consist mainly of ~10 Gyr old stars establishes that they are not protogalaxies; their low metallicities are more likely to be the result of the escape of supernova ejecta, as opposed to youth. These results are consistent with recent galaxy formation simulations which predict that cosmic re-ionization at z ~ 6 significantly limited the subsequent star formation of dwarf galaxies in voids due to the photo-evaporation of baryons from their cold dark matter halos (Abridged).

description: I sistemi sanitari di tutti i paesi occidentali stanno traversando un periodo di profonda trasformazione. I cambiamenti socio economici ed epidemiologici hanno contribuito a mostrare i limiti delle attuali politiche sanitarie ed hanno l’urgenza di porre i servizi territoriali al centro. Questo processo richiede una rivisitazione delle forme organizzative territoriali, delle identità e dei ruoli degli operatori del settore. Questo libro affronta il dibattito su questo processo di cambiamento con particolare attenzione al ruolo dei medici specialisti che operano nel SSN a livello territoriale

Accurate quadratic-response approximation for the self-consistent pseudopotential of semiconductor nanostructures

Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: Quadratic-response theory is shown to provide a conceptually simple but accurate approximation for the self-consistent one-electron potential of semiconductor nanostructures. Numerical examples are presented for GaAs/AlAs and InGaAs/InP (001) superlattices using the local-density approximation to density-functional theory and norm-conserving pseudopotentials without spin-orbit coupling. When the reference crystal is chosen to be the virtual-crystal average of the two bulk constituents, the absolute error in the quadratic-response potential for Gamma(15) valence electrons is about 2 meV for GaAs/AlAs and 5 meV for InGaAs/InP. Low-order multipole expansions of the electron density and potential response are shown to be accurate throughout a small neighborhood of each reciprocal lattice vector, thus providing a further simplification that is confirmed to be valid for slowly varying envelope functions. Although the linear response is about an order of magnitude larger than the quadratic response, the quadratic terms are important both quantitatively (if an accuracy of better than a few tens of meV is desired) and qualitatively (due to their different symmetry and long-range dipole effects).
