Enfranchisement of women
British society in 19th century

description: Η παρούσα εργασία εκπονήθηκε στα πλαίσια του μεταπτυχιακού προγράμματος του τμήματος Φιλοσοφίας- Παιδαγωγικής. Αναφέρεται στην αντιπροσωπευτική δημοκρατία και τη θέση της γυναίκας στην Βρετανία τον 19ο αι. Σκοπός της εργασίας είναι να ερευνηθεί και να διαπιστωθεί αν η αντιπροσωπευτική δημοκρατία, όπως υποστηρίζει ο John Stuart Mill, είναι το ιδεώδες πολίτευμα για κάθε πολυπληθή κοινωνία. Ακόμη, οι γυναίκες ήταν πλήρως υποταγμένες στους συζύγους τους και δεν είχαν καθόλου δικαιώματα. Ο φιλόσοφος, εντούτοις, αποφαίνεται πως πρέπει να τις δοθούν δικαιώματα για να ολοκληρωθούν ως άνθρωποι, αλλά και προς όφελος της κοινωνίας. Εύλογα, λοιπόν, προκύπτουν τα ακόλουθα ερωτήματα. Είναι η αντιπροσωπευτική δημοκρατία το καταλληλότερο πολίτευμα και μπορεί να ανταποκριθεί στις ανάγκες και τις επιδιώξεις του συνόλου των πολιτών; Τέλος, μπορούν οι γυναίκες να θεωρηθούν ισάξιες με τους άντρες, να είναι ανεξάρτητες και αυτόνομες;
description: This paper was produced as part of the graduate program of School of Philosophy and Education department. It refers to representative democracy and the position of women in Britain in the 19th century. The aim of this study is to investigate and determine whether representative democracy, as John Stuart Mill, is the ideal form of government for any crowded society. Moreover, women were fully subservient to their husbands and had no rights. The philosopher, however, decides that rights have been given to them not only to be completed as humans, but also to avail society. Thus, understandably, the following questions arise. Is Representative democracy the best political system and can it meet the needs and aspirations of all citizens? Finally, can women be considered equal to men, to be independent and autonomous?

description: Pose-invariant face recognition refers to the problem of identifying or verifying a person by analyzing face images captured from different poses. This problem is challenging due to the large variation of pose, illumination and facial expression. A promising approach to deal with pose variation is to fulfill incomplete UV maps extracted from in-the-wild faces, then attach the completed UV map to a fitted 3D mesh and finally generate different 2D faces of arbitrary poses. The synthesized faces increase the pose variation for training deep face recognition models and reduce the pose discrepancy during the testing phase. In this paper, we propose a novel generative model called Attention ResCUNet-GAN to improve the UV map completion. We enhance the original UV-GAN by using a couple of U-Nets. Particularly, the skip connections within each U-Net are boosted by attention gates. Meanwhile, the features from two U-Nets are fused with trainable scalar weights. The experiments on the popular benchmarks, including Multi-PIE, LFW, CPLWF and CFP datasets, show that the proposed method yields superior performance compared to other existing methods.
Frequentist versus Bayesian analyses: Cross-correlation as an (approximate) sufficient statistic for LIGO-Virgo stochastic background searches

description: Sufficient statistics are combinations of data in terms of which the likelihood function can be rewritten without loss of information. Depending on the data volume reduction, the use of sufficient statistics as a preliminary step in a Bayesian analysis can lead to significant increases in efficiency when sampling from posterior distributions of model parameters. Here we show that the frequency integrand of the cross-correlation statistic and its variance are approximate sufficient statistics for ground-based searches for stochastic gravitational-wave backgrounds. The sufficient statistics are approximate because one works in the weak-signal approximation and uses measured estimates of the auto-correlated power in each detector. Using analytic and numerical calculations, we prove that LIGO-Virgo's hybrid frequentist-Bayesian parameter estimation analysis is equivalent to a fully Bayesian analysis. This work closes a gap in the LIGO-Virgo literature, and suggests directions for additional searches.

Συγκεκριμένα, αντικείμενο μελέτης και ανάλυσης υπήρξαν αποκλειστικά οι 27 ηθοποιίες που συνέθεσε. Στηριχτήκαμε σε δύο άξονες μελέτης, πάνω στους οποίους κινήθηκε η μεθοδολογική μας μελέτη και ειδικότερα στην παράδοση και την πρωτοτυπία του έργου του. Η παράδοση του ρητορικού είδους της ηθοποιίας υπήρξε μακραίωνη και για το λόγο αυτό κρίθηκε ως ιδιαιτέρως ενδιαφέρον να ερευνηθεί, αν και σε ποιο βαθμό ο Νικηφόρος Βασιλάκης θέλησε να μείνει πιστός στην προγενέστερη παράδοση. Το συμπέρασμα που προέκυψε ήταν ότι ο Βασιλάκης δε θέλησε σε μεγάλο βαθμό να μείνει πιστός στις αρχές του είδους και για τον λόγο αυτό προχώρησε σε διάφορες αλλαγές, οι οποίες θα μπορούσαν κάλλιστα να χαρακτηριστούν ως «καινοτομίες», εφόσον εντοπίστηκαν για πρώτη φορά στο δικό του έργο. Στην αρχή της εργασίας, υπάρχει μια σύντομη, αλλά περιεκτική εισαγωγή αναφορικά με το είδος της ηθοποιίας, ενώ στη συνέχεια παρατίθεται η βιογραφία του ρήτορα. Στο τέλος της εργασίας, ως παράρτημα, έχουν τεθεί οι μεταφράσεις των 27 ηθοποιιών του Βασιλάκη, οι οποίες μεταφράστηκαν σε μια προσπάθεια να γίνουν τα κείμενά του Νικηφόρου Βασιλάκη προσβάσιμα σε κάθε ενδιαφερόμενο.
description: This study attempts to contribute to the study of rhetorical work of Nikiforos Vassilakis, who was the orator of the 12th century AD. In particular, the object of study and analysis were exclusively 27 ethopoiiai he composed. The study was based on two axes, which were start points of our methodological study and particulary on tradition and originality of his work. The tradition of the rhetorical kind of acting was long and because of that it was considered to be particularly interesting to investigate whether and to which extent Nikiforos Vassilakis tried to stay faithful to the earlier tradition. The conclusion drawn was that Vassilakis did not want much to stay faithful to the principles and therefore proceeded to various changes, which could well be described as "innovations", because they were first found in his works. At the beginning of the study, there is a short but comprehensive introduction regarding the type of acting, and then the biography of the orator was presented. At the end of the work, as an appendix, the translations of the 27 ethopoiiai of Vassilakis are presented, which are translated in order to make the texts of Nikiforos Vassilakis accessible to anyone who may be interested in his work.

description: The present research intends to study the modern Greek vignette and more specifically, the readability of this kind on the Internet. As a representative sample (case study), there will be the column "Cynic" by the journalist Kosmas Vidos, which is hosted at the weekly magazine ΒΗΜagazino, and it is also included and uploaded on the electronic version of the newspaper: To Vima. Based on an extensive corpus of texts of the aforesaid journalist, our study attempts to: a) define the columnist type of vignette and highlight its features, characteristics and mixed nature since it is about a textual product which has been developed on the borderline between literature and journalism and b) investigate the readability of this type on the Internet, through posts / readers' comments and finally determine, under which circumstances the features of the Internet and the new ways of reading, have an impact on the editor’s relationship with his readers, the topics and the editor’s attitudes, as well as the redacting procedures in general.
Pentaquark, cusp and rescattering in single kaon photoproduction off deuterium
Creators: name: Laget, J. M.
Publisher: name: arXiv
Year: 2006
Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: In very well defined part of the phase space, $K N$ and $ΛN$ rescattering depend on on-shell elementary matrix elements and on the low momentum components of the deuteron wave function. This provides us with the unique opportunity to study details in the scattering amplitudes that may have escaped the analysis of reactions induced on a nucleon target by Kaon and Hyperon beams at low energies. When folded with a typical experimental mass resolution, a narrow state with a width of 1 MeV would contribute by no more than 10% to the $KN$ mass spectrum. On the contrary, a cusp would be easily detected near the $Σ$ production threshold in the $ΛN$ mass spectrum.
description: 7 pages; 7 figures Updated version after referees' review. Main changes: 1- The contribution of positive parity pentaquark has also been considered; 2- Figure 5 has been added. It shows the expected angular distributions of the contribution of a positive or negative parity pentaquark; 3- Units in Figure 4 and 7 have been updated; 4- The reference list has been updated

description: The flow of segregated bidisperse assemblies of particles is of major importance for geophysical flows and bedload transport in particular. In the present paper, the mobility of bidisperse segregated particle beds was studied with a coupled fluid discrete element method. Large particles were initially placed above small ones and it was observed that, for the same flow conditions, the bedload transport rate is higher in the bidisperse configuration than in the monodisperse one. Depending on the Shields number and on the depth of the interface between small and large particles, different transport phenomenologies are observed, ranging from no influence of the small particles to small particles reaching the bed surface due to diffusive remixing. In cases where the small particles hardly mix with the overlying large particles and for the range of studied size ratios ($r<4$), it is shown that the increased mobility is not a bottom roughness effect, that would be due to the reduction of roughness of the underlying small particles, but a granular flow effect. This effect is analyzed within the framework of the $μ(I)$ rheology and it is demonstrated that the buried small particles are more mobile than larger particles and play the role of a "conveyor belt" for the large particles at the surface. Based on rheological arguments, a simple predictive model is proposed for the additional transport in the bidisperse case. It reproduces quantitatively the DEM results for a large range of Shields numbers and for size ratios smaller than 4. The results of the model are used to identify four different transport regimes of bidisperse mixtures, depending on the mechanism responsible for the mobility of the small particles. A phenomenological map is proposed for bidisperse bedload transport and, more generally, for any granular flow on an erodible bed.

The correlation between the distribution of galaxies and 21cm emission at high redshifts

description: Deep surveys have recently discovered galaxies at the tail end of the epoch of reionization. In the near future, these discoveries will be complemented by a new generation of low-frequency radio observatories that will map the distribution of neutral hydrogen in the intergalactic medium through its redshifted 21cm emission. In this paper we calculate the expected cross-correlation between the distribution of galaxies and intergalactic 21cm emission at high redshifts. We demonstrate using a simple model that overdense regions are expected to be ionized early as a result of their biased galaxy formation. This early phase leads to an anti-correlation between the 21cm emission and the overdensities in galaxies, matter, and neutral hydrogen. Existing Ly-alpha surveys probe galaxies that are highly clustered in overdense regions. By comparing 21cm emission from regions near observed galaxies to those away from observed galaxies, future observations will be able to test this generic prediction and calibrate the ionizing luminosity of high-redshift galaxies.

description: This paper presents an absolute X-ray photon energy measurement method that uses a Bond diffractometer. The proposed system enables the prompt and rapid in-situ measurement of photon energies in a wide energy range. The diffractometer uses a reference silicon single crystal plate and a highly accurate angle encoder called SelfA. We evaluate the performance of the system by repeatedly measuring the energy of the first excited state of the potassium-40 nuclide. The excitation energy is determined as 29829.39(6) eV. It is one order of magnitude more precise than the previous measurement. The estimated uncertainty of the photon energy measurement was 0.7 ppm as a standard deviation and the maximum observed deviation was 2 ppm.
Comparative Legal Perspectives on Cultural Land Trusts for Urban Spaces of Culture, Community, and Art: A Tool for Counteracting Displacement
Creators: name: Ross, Sara Gwendolyn
Publisher: name: Milan Law Review
Year: 2021

description: As cities redevelop and previously less desirable or marginalized portions of the city space are “retaken” by a city, areas that have provided affordable performance, rehearsal, and live/work space for the arts and culture sector are becoming increasingly less available for these uses. Focusing predominantly on the Canadian Civil Law and Common Law context with passing reference to other jurisdictions such as the US, Scotland, and the UK, this article explores techniques for managing the increased pressure on and increasingly rapid displacement of spaces of arts, culture, and community cultural wealth that is taking place in cities. To this end, in assessing newly adopted municipal and provincial cultural strategies that are intended to amplify and promote these same spaces that are being displaced as well as even more recent COVID-19 recovery plans for art and culture in cities, this article will narrow in on the potential application of the community-led cultural land trust structure.

description: TeV gamma-rays may provide significant information about high energy astrophysical accelerators. Such gamma-rays can result from the photo-de-excitation of PeV nuclei after their parents have undergone photo-disintegration in an environment of ultraviolet photons. This process is proposed as a candidate explanation of the recently discovered HEGRA source at the edge of the Cygnus OB2 association. The Lyman-alpha background is provided by the rich O and B stellar environment. It is found that (1) the HEGRA flux can be obtained if there is efficient acceleration at the source of lower energy nuclei; (2) the requirement that the Lorentz-boosted ultraviolet photons can excite the Giant Dipole resonance implies a strong suppression of the gamma-ray spectrum compared to an E_γ^{-2} behavior at energies \alt 1 TeV (some of these energies will be probed by the upcoming GLAST mission); (3) a TeV neutrino counterpart from neutron decay following helium photo-disintegration will be observed at IceCube only if a major proportion of the kinetic energy budget of the Cygnus OB2 association is expended in accelerating nuclei.

description: By analyzing the Chandra ACIS S3 data we studied the X-ray properties of the low-mass and high-mass X-ray binary populations in the nearby spiral galaxy NGC 5055. A total of 43 X-ray point sources were detected within the 2 effective radii, with 31 sources located on the disk and the rest 12 sources in the bulge. The resolved point sources dominate the total X-ray emission of the galaxy by accounting for about 80% of the total counts in 0.3--10 keV. By carrying out the spectral fittings we calculated the 0.3--10.0 keV luminosities of all the detected X-ray point sources and found that they span a wide range from a few 10^{37} erg s^{-1} to over 10^{39} erg s^{-1}. After compensating for the incompleteness at the low luminosity end, we find that the corrected XLF of the bulge population is well fitted with a broken power-law model with a break at 1.57^{+0.21}_{-0.20}\times 10^{38} erg s^{-1}, while the profile of the disk population's XLF agrees with a single power-law distribution with a slope of 0.93^{+0.07}_{-0.06}. The disk population is significantly richer at {}^{>}_{\sim}2\times10^{38} erg s^{-1} than the bulge population, inferring that the disk may have undergone relatively recent, strong starbursts that significantly increased the HMXB population, although ongoing starbursts are also observed in the nuclear region. Similar XLF profiles of the bulge and disk populations were found in M81. However, in most other spiral galaxies different patterns of the spatial variation of the XLF profiles from the bulge to the disk have been observed, indicating that the star formation and evolution history may be more complex than we have expected.

description: We discuss resonance properties in three-body systems, with examples on $^{12}{\rm C}$ and $^{24}{\rm Mg}$. We use a microscopic cluster model, where the generator coordinate is defined in the hyperspherical formalism. The $^{12}{\rm C}$ nucleus is described by an $α+α+α$ structure, whereas $^{24}{\rm Mg}$ is considered as an $^{16}{\rm O}+α+α$ system. We essentially pay attention to resonances. We review various techniques which may extend variational methods to resonances. We consider $0^+$ and $2^+$ states in $^{12}{\rm C}$ and $^{24}{\rm Mg}$. We show that the r.m.s. radius of a resonance is strongly sensitive to the variational basis. This has consequences for the Hoyle state ($0^+_2$ state in $^{12}{\rm C}$) whose radius has been calculated or measured in several works. In $^{24}{\rm Mg}$, we identify two $0^+$ resonances slightly below the three-body threshold.

description: Grapevine virus A (GVA), Grapevine virus B (GVB) and Grapevine rupestris stem pitting associated virus (GRSPaV), are considered to have a worldwide distribution and are closelyassociated with the Rugose wood (RW) complex. Their serological and molecular identification is unreliable due to their high genetic variability. The aim of this study was to develop reliable methods for their detection and also to estimate their frequency in Greek vineyards. Furthermore,the genetic variability of Greek GVA and GRSPaV isolates was studied. For each virus a method of reverse transcription - polymerase chain reaction (RT-PCR) wasdeveloped using degenerate primers that target the capsid protein (CP)gene.The developed RT-PCRs exhibit a wide detection range and they were further applied for the study of the occurrence of GVA, GVB and GRSPaV in rootstocks, own-rooted and grafted grapevine varieties. Finally, sequence comparison among 13 Greek isolates of GVA and isolates available in the databases, showed high nucleotide variability ranging between 1-27%. Likewise, sequence comparison among 14 Greek isolates of GRSPaV and isolates available in the databases, revealed nucleotide variability ranging between 1-21%.

Democratic experimentalism in comparative constitutional social rights remedies
Creators: name: Mukherjee, Gaurav
Publisher: name: Milan Law Review
Year: 2021

description: Arguments in favor of democratic experimentalism in the adjudication of social rights focus on its ability to foster democratic engagement through deliberation and learning about party preferences in litigation, while also decentering the court and permitting the representation of a broader range of stakeholders and interests in the judicial process. However, experimentalist processes can be normatively weak, reinforce deliberative inequalities between parties, and can expose the limits to localized solutions. The academic literature on experimentalism in social rights cases has focused on discrete, but related strands of the adjudicative process, focusing on forms of dialogic remedies, catalytic remedial practices, and empowered participatory jurisprudence. In this article, I locate recent adjudicative practice by the judiciaries in India and South Africa within the democratic experimentalist framework. Part I of the article lays out the general theoretical framework to understand democratic experimentalist practices which helps us spot what is - and is not - judicial practice that adheres to such a framework, while also laying out the strengths and weaknesses of such approaches. I claim that a democratic experimentalist framework is an analytic, rather than a descriptive category of judicial approaches. Part II offers a novel framework to understand democratic experimentalist approaches to the adjudicative enterprise by suggesting that they are best understood as: a) ways of arriving at a remedy in social rights litigation (experimentalist remedial design), b) ways of following up, monitoring, and evaluating compliance with the judgments and orders of a court (experimentalist remedial oversight). Parts III and IV use the framework developed in Part II to describe two cases each from South Africa and India, which used, with varying degrees of success, democratic experimentalist approaches to adjudication. I conclude by reading the tealeaves and sketching the prospects for such an approach in future cases in these two courts, as well as courts around the world – when adjudicating social rights. Keywords: Democratic experimentalism – Socioeconomic rights – Judicial review –Separation of powers – Comparative constitutional studies

description: The schooner Lucy, of Portmadoc Capt. Roberts, when making for this bar on Sunday morning last, about 7 a.m., grounded, when it afterwards came to blow very fresh from S. W. the vessel still continuing aground and unmanageable, and although every effort was made to save the ship and cargo, it became a total wreck. She was bound from Newcastle for Portmadoc, with coals. Her rigging, spars, sails, andc., were sold by auction, and the remainder of the vessel has since disappeared. We are glad that the vessel and cargo were insured.

description: This Comment suggests that technological field electron emission (FE) papers, such as the paper under discussion [P. Serbun et al.,, Rev. Sci. Instrum. 91, 083906 (2020)], should use FE theory based on the 1956 work of Murphy and Good (MG), rather than a simplified version of FE theory based on the original 1928 work of Fowler and Nordheim (FN). Use of the 1928 theory is common practice in technological FE literature, but the MG treatment is known to be better physics than the FN treatment, which contains identifiable errors. The MG treatment predicts significantly higher emission current densities and currents for emitters than does the FN treatment. From the viewpoint of the research and development of electron sources, it is counterproductive (and unhelpful for non-experts) for the technological FE literature to use theory that undervalues the performance of field electron emitters.

A Comparative Study of the Political Question Doctrine in the Context of Political-System Failures: The United States and the United Kingdom
Creators: name: Lawrence, Hayley N.
Publisher: name: Milan Law Review
Year: 2021

description: In 2019, the Supreme Courts of both the United States and the United Kingdom decided cases involving the political question doctrine. In Rucho v. Common Cause, the U.S. Supreme Court held that partisan gerrymandering claims raise inherently political questions because the Court was unable to discern judicially manageable standards for determining when a partisan gerrymander had gone “too far.” Whereas, in R v. The Prime Minister (“Miller”), the United Kingdom Supreme Court adopted a narrower view of the political question doctrine, unanimously ruling that although the case involved political actors and the royal prerogative, it did not present a political question. The Court then proceeded to decide the case on the merits, holding that the Prime Minister exceeded his authority in prorogating Parliament before the Brexit deadline. The response of the judiciary—whether to abdicate or to intervene—presents a study in stark contrasts. This paper evaluates Rucho by comparing the United States’ and United Kingdom’s respective political question doctrines through the lens of John Hart Ely’s representation-reinforcement theory of judicial review. According to Ely, the judiciary is uniquely competent to intervene like referees when one side gets an unfair advantage—not when the “wrong side” scores. Translated into legal theory, that means that when the political processes are undeserving of trust, either because certain groups are denied access or because representatives are operating in flagrant disregard of constituents’ interests, courts are fully capable of determining when the political branches have gone “too far.” Both cases illustrate why the Court’s duty to protect from state infringement individual liberties related to democratic participation is at its zenith when system failures denigrate the political process. In Rucho, the Court ignored this calling, abdicating its duty to intervene. Examining Miller reveals where the Court erred in Rucho: (1) Miller is an exemplar of the representation-reinforcement theory of judicial review, (2) Miller offers critical insights to contrast the Court’s approach in Rucho, and (3) Miller offers an example of “judicially manageable standards” for determining when a branch has exceeded the constitutional boundaries of its powers—a standard that the majority in Rucho so desperately seeks. At bottom, Rucho got it wrong—and Miller can help us see why.

description: The LUTHER was a wooden snow or brig (sources differ) built by the Dundee Shipbuilding Company in 1856. Technical and configuration specifications are given as 249gt, 214nt; 100ft 3in length x 23ft 3in breadth x 15ft 3in depth; sheathed in felt and yellow metal, partly fastened with iron bolts. At time of loss on 24 January 1884, the vessel was owned by J White of Dundee and was carrying coal or beer, stout, and Scotch whisky in 40-60 gallon barrels (sources differ) from Troon to St John Newfoundland. The vessel was manned by 9 crew members, including the master John Duncan or D Stewart (sources differ) and the master's son. The LUTHER was caught in a northwesterly force 11 gale and blown ashore near Porth Oer. At about 2 o'clock in the morning of 25 January 1884 , two of the crewmen arrived at a farm called Ty Mawr, saying that they had left another two crewmen on the road. A search was made, and the men brought safely to the house. Those that were saved included an old man, the cook and two able-seamen, Gilbert Ross and John Jeness. The captain's body was found at Clyanng, 20 miles away. Another man reached the shore by clinging to the ship's biscuit tin.

description: Η ποιότητα ενός προϊόντος είναι το μέτρο της εμπιστοσύνης, ότι το προϊόν πληροί τις προδιαγραφές. Εξίσου σημαντική προϋπόθεση είναι η αξιοπιστία, η οποία εξαρτάται από την συνέπεια στην παράδοση του προϊόντος, δηλαδή είναι εξαρτημένη από το χρόνο. Και τα δύο έχουν άμεση σχέση με το κόστος. Στην παρούσα διπλωματική εργασία, λοιπόν, εξετάζουμε μαθηματικά μοντέλα για την βελτιστοποίηση της αξιοπιστίας συστημάτων πολλαπλών αποκρίσεων που εξαρτώνται από το χρόνο, προτείνοντας μια μέθοδο και συγκρίνοντας την με τις υπόλοιπες. Η μεθοδολογία αυτή χρησιμοποιείται και στο σχεδιασμό του κόστους του κύκλου ζωής ενός προϊόντος, με σκοπό τη μείωση του κόστους αλλά και με σεβασμό στην ποιότητα. Το κλειδί για την προσέγγιση της προτεινόμενης μεθόδου, είναι ο υπολογισμός της αθροιστικής πιθανότητας αποτυχίας του συστήματος. Για αυτό, χρησιμοποιείται μια ισοδύναμη χρονικά αναλλοίωτη σύνθετη οριακή κατάσταση και ένας αλγόριθμος niching με μια τεμπέλικη μάθηση μεταμοντελισμού. Στο τέλος της εργασίας παρατίθεται ένα παράδειγμα ταλαντευόμενου συστήματος δύο σωμάτων και ένα παράδειγμα κυλινδρικού συμπλέκτη από το χώρο της αυτοκίνησης, που επιδεικνύουν τον υπολογισμό της αθροιστικής πιθανότητας αποτυχίας και το σχεδιασμό του κόστους στον κύκλο ζωής του προϊόντος.
description: Quality is a measure of confidence that the product conforms to specifications. Reliability, which depends on the consistent delivery of the product, therefore on the time, is an important requirement too. Both of them are related to cost. So, in the present master thesis, we study mathematical models which optimize the reliability of time-dependent multiresponse systems, proposing one method and comparing it with others. This method is used in the design of lifecycle cost of a product, aiming to reduce costs without reducing quality. The key of the proposed method, is the calculation of the system cumulative probability of failure. For that, an equivalent time invariant composite limit state and a niching genetic algorithm with lazy learning metamodeling are used. In the end of this study, a two-mass vibratory system example and an automotive roller clutch example are given, to demonstrate the calculation of the cumulative probability of failure and the design of lifecycle cost.

description: Main subject of this project is Job Scheduling in distributed systems as mentioned above. Six scenarios were implemented based mainly on two of them: Minimum Load is the first scenario and Probabilities is the second one. There were two variation on the above scenarios based on the service of the tasks that composed each job. At first, we examined only the parallel service of the tasks and as a variation of the scenarios we used a fixed probability (20%, 30%) of both parallel and serial service. The project is structured into chapters as follows: In Chapter 1, we present the necessity of efficient job scheduling algorithms in order to perform better simulation strategies in distributed systems. In Chapter 2, we refer to the basic elements of Simulation. In Chapter 3, there is a brief presentation of Grid systems. In Chapter 4, we refer to key elements of performance analysis, factors that characterize a system as well as performance metrics. In Chapter 5, we have an analysis of the system as well as brief analysis of the system implementation. Finally, the last chapter presents the results of experiments with various parameters used along with bar charts, tables and graphs with the analytical values of the extracts files.

description: Exact eigenstates for a set of two or more interacting electronic orbits in a magnetic field are studied for a class of factorized Hamiltonians with coupled Fermi surfaces. We study the condition for the existence of annihilation-creation operators that allows for the construction of eigenstates. For the case of two interacting cyclotronic orbits, we consider the oscillations of the overlap function and the transfer of charge density between the orbits as function of the inverse field. The expressions of the Fourier frequencies are given in the semiclassical regime and they depend on the geometrical structure of the electronic bands. A generalization of this construction is provided for a chain of several interacting orbits with exact eigenfunctions.
