description: The class of ω regular languages provide a robust specification language in verification. Every ω-regular condition can be decomposed into a safety part and a liveness part. The liveness part ensures that something good happens “eventually.” Two main strengths of the classical, infinite-limit formulation of liveness are robustness (independence from the granularity of transitions) and simplicity (abstraction of complicated time bounds). However, the classical liveness formulation suffers from the drawback that the time until something good happens may be unbounded. A stronger formulation of liveness, so-called finitary liveness, overcomes this drawback, while still retaining robustness and simplicity. Finitary liveness requires that there exists an unknown, fixed bound b such that something good happens within b transitions. In this work we consider the finitary parity and Streett (fairness) conditions. We present the topological, automata-theoretic and logical characterization of finitary languages defined by finitary parity and Streett conditions. We (a) show that the finitary parity and Streett languages are Σ2-complete; (b) present a complete characterization of the expressive power of various classes of automata with finitary and infinitary conditions (in particular we show that non-deterministic finitary parity and Streett automata cannot be determinized to deterministic finitary parity or Streett automata); and (c) show that the languages defined by non-deterministic finitary parity automata exactly characterize the star-free fragment of ωB-regular languages.

description: A recent article (Khair and Kabarowski; Phys. Rev. Fluids 5, 033702) has studied the cross-streamline migration of electrophoretic particles in unbounded shear flows with weak inertia or viscoelasticity. That work compares their results with those reported in two of our previous studies (Choudhary et al.: J. Fluid Mech. 874; J. Fluid Mech. 898) and reports a disagreement in the derived analytical expressions. In this comment, we resolve this discrepancy. For viscoelastic flows, we show that Khair and Kabarowski have not accounted for a leading order surface integral of polymeric stress in their calculation of first-order viscoelastic lift. When this integral is included, the resulting migration velocity matches exactly with that reported in our work (J. Fluid Mech. 898). This qualitatively changes the migration direction that is reported by Khair and Kabarowski for viscoelastic flows. For inertial flows, we clarify that Khair and Kabarowski find the coefficient of lift to be 1.75$π$, compared to 2.35$ π$ in our previous work (J. Fluid Mech. 874). We show that this difference occurs because Khair and Kabarowski accurately include the effect of rapidly decaying $ \sim O(1/r^{4}) $ velocity field (a correction to the stresslet field $ \sim 1/r^{2} $), which was neglected in our previous work (J. Fluid Mech. 874).

description: We report the experimental observation of a "devil's staircase'' in a time dependent system considered as a paradigm for the transition to large scale chaos in the universality class of hamiltonian systems. A test electron beam is used to observe its non-self-consistent interaction with externally excited wave(s) in a Travelling Wave Tube (TWT). A trochoidal energy analyzer records the beam energy distribution at the output of the interaction line. An arbitrary waveform generator is used to launch a prescribed spectrum of waves along the slow wave structure (a 4 m long helix) of the TWT. The resonant velocity domain associated to a single wave is observed, as well as the transition to large scale chaos when the resonant domains of two waves and their secondary resonances overlap. This transition exhibits a "devil's staircase'' behavior for increasing excitation amplitude, due to the nonlinear forcing by the second wave on the pendulum-like motion of a charged particle in one electrostatic wave.

description: Boolean notions of correctness are formalized by preorders on systems. Quantitative measures of correctness can be formalized by real-valued distance functions between systems, where the distance between implementation and specification provides a measure of “fit” or “desirability.” We extend the simulation preorder to the quantitative setting, by making each player of a simulation game pay a certain price for her choices. We use the resulting games with quantitative objectives to define three different simulation distances. The correctness distance measures how much the specification must be changed in order to be satisfied by the implementation. The coverage distance measures how much the im- plementation restricts the degrees of freedom offered by the specification. The robustness distance measures how much a system can deviate from the implementation description without violating the specification. We consider these distances for safety as well as liveness specifications. The distances can be computed in polynomial time for safety specifications, and for liveness specifications given by weak fairness constraints. We show that the distance functions satisfy the triangle inequality, that the distance between two systems does not increase under parallel composition with a third system, and that the distance between two systems can be bounded from above and below by distances between abstractions of the two systems. These properties suggest that our simulation distances provide an appropriate basis for a quantitative theory of discrete systems. We also demonstrate how the robustness distance can be used to measure how many transmission errors are tolerated by error correcting codes.

Technology and change in national defense planning in the twentieth century
Creators: name: Carter, Tim
Publisher: name: University of British Columbia
Year: 2008

description: The national security policies of the great powers have changed dramatically since the turn of the century. These changes have had vast implications for the study of international relations. This thesis examines the role of technology in changing national security policies during the twentieth century. In order to do so, two issues are addressed. First, how is national security policy formed, and how does it change. Second, what role has technology played in this process, and how has this role changed over time. Three historical cases are developed to address these questions. Each case highlights a different period in time and in technological development. Together, the three cases incorporate most of the major technological changes of the twentieth century, as well as the main streams of thought regarding the importance of these changes to security planning. Three possible models for explaining the development of national security policy, and technology's role in it, are developed and applied across the appropriate cases. Each model provides insight into the nature of the national security policy at one particular point in time. Since the turn of the century, national security policy has been radically revised at every level of planning. The conceptual foundation upon which security policy was constructed has been fundamentally altered. Threats to the state have changed, as have responses to those threats. Traditional notions, such as the defense of the state, have been discarded in favor of security through deterrence. The concept of deterrence itself has changed, as traditional methods of deterring attacks no longer apply. In each case the extent of these changes is more apparent. Similarly, in each case the role of technology in creating these changes is more dominant. By 1960, the role of technology is the single most important factor in understanding national security policy. Technology shapes not only the methods by which a state may be secured, but also the conditions of its security problem. The penultimate technological development, nuclear weapons, has truly revolutionized national security and, therefore, national security policy.

description: The aim of this study is to probe the influence of water vapor environment on the microtribological properties of a forestlike vertically aligned carbon nanotube (VACNT) film, deposited on a silicon (001) substrate by chemical vapor deposition. Tribological experiments were performed using a gold tip under relative humidity varying from 0 to 100%. Very low adhesion forces and high friction coefficients of 0.6 to 1.3 resulted. The adhesion and friction forces were independent of humidity, due probably to the high hydrophobicity of VACNT. These tribological characteristics were compared to those of a diamond like carbon (DLC) sample.

description: For the Delta Scuti star 44 Tau 13 independent frequencies have been detected in previous studies. This star is unusual among the Delta Scuti stars because of its very low v sin i value of 2 +/- 1 km/s, indicating that it is either an extremely slow rotator or seen pole-on. 44 Tau shows unusually high amplitudes for a typical nonradially pulsating Delta Scuti star and is believed to be a connecting link between the high-amplitude Delta Scuti stars (HADS) and the low-amplitude Delta Scuti stars. We performed an asteroseimic study to find the appropriate theoretical model for this star. The fact that the radial fundamental and first overtone frequencies have been identified allows for reducing the number of possible solutions significantly. Standard post-main sequence models with inefficient convection in the envelope seem to be preferable in comparison with various models on the main sequence. They fit both observed global parameters of 44 Tau and most of identified radial and nonradial frequencies.

description: We present an inelastic neutron scattering study of the low energy crystal-field excitations in the lightly doped cobalt perovskite La_0.998Sr_0.002CoO_3. In contrast to the parent compound LaCoO_3 an inelastic peak at energy transfer ~0.75 meV was found at temperatures below 30 K. This excitation apparently corresponds to a transition between a ground state orbital singlet and a higher excited orbital doublet, originating from a high-spin triplet split by a small trigonal crystal field. Another inelastic peak at an energy transfer ~0.6 meV was found at intermediate temperatures starting from T > 30 K. This confirms the presence of a thermally induced spin-state transition from the low-spin Co^3+ to a magnetic high-spin state in the non-disturbed LaCoO_3 matrix. We suggest that hole doping of LaCoO_3 leads to the creation of a magnetic polaron and hence to the low-to-high spin state transition on the relevant Co sites.

description: The research study discusses the effectiveness of the EU’s Common Security and Defence Policy (CSDP) and identifying the challenges in the successful deployment of CSDP missions. It explores the historical overview of the EU’s CSDP, from the Treaty of Maastricht, 1992 to the establishment of Permanent Structured Cooperation (PESCO) and addresses to the interaction between CSDP and NATO. It is observed that the EU has been focused on strengthening CSDP to address defence and security-related challenges trying to rely less on NATO. However, it has encountered challenges with the member States as some of the EU members prioritise national interest over collective security and defence of the EU. Although the EU members have faced complex security threats, which emphasises on the growing need for a CSDP, there are certain challenges, including national priorities, economic crisis and Euroscepticism which are affecting and may also affect CSDP in future.

Παρατηρείται ότι η ΕΕ έχει εστιάσει στην ενδυνάμωση της ΚΠΑΑ προκειμένου να αντιμετωπίσει αυτόνομα τα θέματα άμυνας και ασφάλειας της δείχνοντας ότι επιθυμεί την ανεξαρτητοποίηση της από το ΝΑΤΟ. Ωστόσο, στην προσπάθειά της αυτή έχει συναντήσει σημαντικές προκλήσεις με τα κράτη-μέλη της, καθώς κάποια από αυτά προωθούν το εθνικό τους συμφέρον εις βάρος της συλλογικής άμυνας και της ασφάλειας της ΕΕ και των ευρωπαϊκών συμφερόντων γενικότερα. Το γεγονός ότι τα κράτη-μέλη έχουν να αντιμετωπίσουν σύνθετες και σοβαρές απειλές για την ασφάλειά τους οδηγεί σε μία συνεχώς αυξανόμενη ανάγκη για μία κοινή πολιτική άμυνας εντός της ΕΕ. Ωστόσο υπάρχουν συγκεκριμένες προκλήσεις συμπεριλαμβανομένων των εθνικών προτεραιοτήτων, της οικονομικής κρίσης και του Ευρωσκεπτικισμού που επηρεάζουν και πιθανόν να βλάψουν την ΚΠΑΑ στο μέλλον.
The impact of royal commissions on public policy : worker’s compensation in British Columbia, 1941-1968
Creators: name: Chaklader, Anjan K.
Publisher: name: University of British Columbia
Year: 2008

description: During the years 1941 to 1968, issues relating to workers’ compensation in British Columbia were subjected to the unprecedented number of three royal commissions. An explanatory framework that evaluates the merits of the commissions and their recommendations, both perceived and otherwise, and the degree to which governments adopted the recommendations, is presented in this paper. The framework is designed to make use of the available relevant primary sources, particularly minutes of the commission proceedings, newspaper accounts and legislative statutes. All three of the Commissions were thorough, well-received exercises whose recommendations were almost wholly adopted by B.C. governments, though in differing time frames. The need for the second Commission, which was created a mere six years after the finish of the first, primarily arose because of rapid developments in the B.C. labour movement during the mid-1940’s. An infusion of leaders with communist ties caused it to harden demands for workers’ compensation benefits and reforms. The first Commission had been considered a success by all parties, but the context of its recommendations had changed due to the increase in labour’s militancy. This second Commission was also considered to be reasonably successful. However, dissatisfaction with a Workmen’s Compensation Board that had completely turned over shortly after the second Commission, led to demands, particularly by labour, to create another commission to review its work and procedures. Board members, at that time, were subject to long tenures and were without any formal mechanism with which to be reviewed. Critical to the success of the three Commissions was the independent, non-partisan nature of their proceedings and recommendations. Because of this, the credibility accorded to the recommendations, particularly by labour, caused the Commissions to supercede the traditional mode of cabinet or legislative committtee deliberation for public policy formation in this case. The series of Commissions ended because of satisfaction with the Workmen’s Compensation Act, a much higher turnover rate of the Board and increased strength of the provincial labour-backed New Democratic Party. Thus, the Commissions and the three B.C. Supreme Court Justices that served as the Commissioners, must go down in history has having played a significant role in the evolution of occupational safety and health policy in British Columbia.

description: The system of several (N) quantum dots coupled in parallel to the same single-mode conduction channel can be modelled as a single-channel N-impurity Anderson model. Using the generalized Schrieffer-Wolff transformation we show that near the particle-hole symmetric point, the effective Hamiltonian in the local moment regime is the N-impurity S=1/2 Kondo model. The conduction-band-mediated RKKY exchange interaction between the dots is ferromagnetic and at intermediate temperatures locks the moments into a maximal spin S=N/2 ground state. We provide an analytical estimate for the RKKY interaction. At low temperatures the spin is partially screened by the conduction electrons to N/2-1/2 due to the Kondo effect. By comparing accurate numerical renormalization group results for magnetic susceptibility of the N-impuriy Anderson model to the exact Bethe-Ansatz results of a S=N/2 SU(2) Kondo system we show, that at low-temperature the quantum dots can be described by the effective S=N/2 Kondo model. Moreover, the Kondo temperature is independent of the number of impurities N. We demonstrate the robustness of the spin N/2 ground state as well as of the associated S=N/2 Kondo effect by studying the stability of the system with respect to various experimentally relevant perturbations. We finally explore various quantum phase transitions driven by these perturbations.

description: In an era where both international and regional tensions are escalating perilously and the established status quo and current world order are challenged in multiple levels by both dominant and developing powers, this paper aims to shed some light to the profound processes that lead the global system into restructuring or even transformation. The choice of Turkey as the structural axis of the analysis is not without merit. As we follow the evolution of the Turkish foreign policy since the end of the bipolar world and up until the developing events of the Arab Spring, we come across a multitude of shifts in both the stance and the role of the country in the regional and global geopolitical arena. In the following analysis I seek to underline the renewed role of Turkey as well as the rest of the developing powers in the formation of the correlations that determine and define the geopolitical reality of the early 21st century

description: The current thesis concerns three different aspects of seismology, seismicity, seismic hazard assessment and strong ground motion simulation for the island of Lesvos. In the first and introductory chapter the island’s geology, tectonics, historical earthquakes and the seismic sequence of June 2017 are discussed. In Chapter 2 some theoretical concepts regarding time independent seismicity are mentioned, which are later applied into two separate catalogs which extend over the time intervals 1995-2017 and 1911-2016. Chapter 3 deals with probabilistic seismic hazard assessment. The method’s basic principles are described in detail, and then the method is applied for the island of Lesvos using the logic tree approach .Finally, chapter 4 deals with strong ground motion simulation, initially retrospectively using existing records, and then for the location of Vrisa, which was hit the hardest by the Mw=6.3 earthquake. The basic theoretical concepts of the method are also mentioned. The fifth and final chapter discusses the results of this work and outlines the conclusions that can be drawn from them

Πιο συγκεκριμένα, οι ερωτηθέντες ήταν μέλη ενός Προγράμματος του ΚΕΘΕΑ στο πλαίσιο του σωφρονιστικού συστήματος στη Βόρεια Ελλάδα (ΚΕΘΕΑ ΠΡΟΜΗΘΕΑΣ). Συλλέχθηκαν 113 ερωτηματολόγια, εκ των οποίων τα 85 αντιστοιχούν σε άτομα που παρακολουθούν το Πρόγραμμα εντός των καταστημάτων κράτησης - είτε σε στάδιο συμβουλευτικής, είτε σε στάδιο κύριας θεραπείας - και τα 28 σε αποφυλακισμένα άτομα στη φάση της υποδοχής και κοινωνικής επανένταξης. Τα ευρήματα έδειξαν ότι οι τρείς σημαντικότεροι θεραπευτικοί παράγοντες καθ’ όλη τη διάρκεια της θεραπείας αναδείχθηκαν οι: ενστάλαξη της ελπίδας, συνεκτικότητα της ομάδας, υπαρξιακοί παράγοντες. Αντίθετα, λιγότερο σημαντικοί θεραπευτικοί παράγοντες σημειώθηκαν οι: ταύτιση, αλτρουισμός, καθοδήγηση. Στην παρούσα μελέτη καταγράφονται οι μεταβλητές που επηρεάζουν και μεταβάλλουν τη σημαντικότητα των θεραπευτικών παραγόντων. Τα αποτελέσματα της έρευνας επιβεβαιώνουν το σημαντικό ρόλο των παραγόντων αυτών στη θεραπεία των εξαρτήσεων και ιδιαίτερα στον πληθυσμό των σωφρονιστικών καταστημάτων κράτησης
description: The goal of the present quantitative research is the study of therapeutic factors witch, according to Yalom (2006), effect on changes in therapeutic procedure. The evaluation of the influence in the twelve factors has been done by the members in drug treatment Program. This Program of KETHEA (therapeutic center for independent individuals) take place in Northern Greece and trade in the correction system (KETHEA- PROMITHEAS). The sable included 113 clients. Prisoners- members in therapeutic unit was 85 and the rest 28 was individuals who was re-incarcerated and are members of the social re-integration unit. The results shows that the three most valued therapeutic factors were the instillation of hope, the cohesiveness and the existential factors. From the other hand, the three less value therapeutic factors was identification, altruism and guidance. In the present study also reported the variables that effects on valuation of factors. The results confirm the importance role of those twelve factors in drug treatment program, especially in prisoner’s drug addicts

description: The atmospheres of close-in extrasolar planets absorb most of the incident stellar radiation, advect this energy, then reradiate photons in preferential directions. Those photons carry away momentum, applying a force on the planet. Here we evaluate the resulting secular changes to the orbit, known as the Yarkovsky effect. For known transiting planets, typical fractional changes in semi-major axis are about 1% over their lifetime, but could be up to ~5% for close-in planets like OGLE-TR-56b or inflated planets like TrES-4. We discuss the origin of the correlation between semi-major axis and surface gravity of transiting planets in terms of various physical processes, finding that radiative thrusters are too weak by about a factor of 10 to establish the lower boundary that causes the correlation.

description: The forgetting of the initial distribution for discrete Hidden Markov Models (HMM) is addressed: a new set of conditions is proposed, to establish the forgetting property of the filter, at a polynomial and geometric rate. Both a pathwise-type convergence of the total variation distance of the filter started from two different initial distributions, and a convergence in expectation are considered. The results are illustrated using different HMM of interest: the dynamic tobit model, the non-linear state space model and the stochastic volatility model.

description: A method is introduced for solving Einstein's equations using two distinct coordinate systems. The coordinate basis vectors associated with one system are used to project out components of the metric and other fields, in analogy with the way fields are projected onto an orthonormal tetrad basis. These field components are then determined as functions of a second independent coordinate system. The transformation to the second coordinate system can be thought of as a mapping from the original ``inertial'' coordinate system to the computational domain. This dual-coordinate method is used to perform stable numerical evolutions of a black-hole spacetime using the generalized harmonic form of Einstein's equations in coordinates that rotate with respect to the inertial frame at infinity; such evolutions are found to be generically unstable using a single rotating coordinate frame. The dual-coordinate method is also used here to evolve binary black-hole spacetimes for several orbits. The great flexibility of this method allows comoving coordinates to be adjusted with a feedback control system that keeps the excision boundaries of the holes within their respective apparent horizons.

Bounded rationality in concurrent parity games

Publisher: name: IST Austria
Year: 2011
Subjects: 000 Computer science, knowledge & general works

description: We consider 2-player games played on a finite state space for an infinite number of rounds. The games are concurrent: in each round, the two players (player 1 and player 2) choose their moves independently and simultaneously; the current state and the two moves determine the successor state. We study concurrent games with ω-regular winning conditions specified as parity objectives. We consider the qualitative analysis problems: the computation of the almost-sure and limit-sure winning set of states, where player 1 can ensure to win with probability 1 and with probability arbitrarily close to 1, respectively. In general the almost-sure and limit-sure winning strategies require both infinite-memory as well as infinite-precision (to describe probabilities). We study the bounded-rationality problem for qualitative analysis of concurrent parity games, where the strategy set for player 1 is restricted to bounded-resource strategies. In terms of precision, strategies can be deterministic, uniform, finite-precision or infinite-precision; and in terms of memory, strategies can be memoryless, finite-memory or infinite-memory. We present a precise and complete characterization of the qualitative winning sets for all combinations of classes of strategies. In particular, we show that uniform memoryless strategies are as powerful as finite-precision infinite-memory strategies, and infinite-precision memoryless strategies are as powerful as infinite-precision finite-memory strategies. We show that the winning sets can be computed in O(n2d+3) time, where n is the size of the game structure and 2d is the number of priorities (or colors), and our algorithms are symbolic. The membership problem of whether a state belongs to a winning set can be decided in NP ∩ coNP. While this complexity is the same as for the simpler class of turn-based parity games, where in each state only one of the two players has a choice of moves, our algorithms,that are obtained by characterization of the winning sets as μ-calculus formulas, are considerably more involved than those for turn-based games.

description: Σκοπός της παρούσας έρευνας ήταν να αξιολογηθεί η επίδραση ενός προγράμματος παρέμβασης Yoga, στην ευλυγισία, τη σταθερότητα του κορμού και τον κινητικό συντονισμό εφήβων με και χωρίς κινητικές δυσκολίες. Στην έρευνα συμμετείχαν 70 μαθητές/τριες γυμνασίου, και αξιολογήθηκαν αρχικά, με το M-ABC-ΙΙ ώστε να δημιουργηθούν οι τέσσερις ομάδες. Η πειραματική ομάδα (yoga) με άτυπη ΑΔΚΣ (α-ΑΔΚΣ), (Ν = 8), η πειραματική ομάδα (yoga) τυπικού κινητικού συντονισμού (ΤΚΣ), (Ν = 8) και οι δύο ομάδες ελέγχου με α-ΑΔΚΣ (Ν = 8) και ΤΚΣ (Ν = 8). Το πρόγραμμα παρέμβασης διήρκησε 8 εβδομάδες και πραγματοποιούνταν 2 συνεδρίες Yoga την βδομάδα για 45 λεπτά. Πριν και μετά τις 8 εβδομάδες, όλοι οι μαθητές μετρήθηκαν στην δοκιμασία ‘sit and reach’ και ‘sit up test’ και μόνο οι ομάδες με α-ΑΔΚΣ αξιολογήθηκαν και με το Μ-ABC-II. Τα αποτελέσματα έδειξαν ότι το πρόγραμμα παρέμβασης δεν βελτίωσε τις κινητικές δυσκολίες των παιδιών με α-ΑΔΚΣ ( p> .05), αλλά βελτίωσε στατιστικά σημαντικά ( p < .05), τη δυναμη των κοιλιακών και την ευλυγισια και στις δύο πειραματικές ομάδες (α-ΑΔΚΣ και ΤΚΣ ). Συμπερασματικά, η Yoga φάνηκε να είναι μία μορφή άσκησης κατά την οποία, οι έφηβοι/ες με διαφορετικό επίπεδο κινητικού συντονισμού μπορούν να βελτιώσουν δείκτες φυσικής κατάστασης, όπως η δύναμη του κορμού και η ευλυγισία, σε περιβάλλον σχολείου, οδηγώντας ειδικά τους/τις εφήβους με α-ΑΔΚΣ να απεμπλακούν από το φαύλο κύκλο αποφυγής της φυσικής δραστηριότητας, και να βοηθήσει γενικά, όλους/ες τους/τις εφήβους, ανεξάρτητα από τις κινητικές δυσκολίες, να αποκτήσουν ένα δραστήριο τρόπο ζωής, με όλα τα οφέλη στην υγεία τους
description: The purpose of the present study was to evaluate the effect of a yoga intervention program on flexibility, trunk stability and motor coordination, in adolescents with or without motor difficulties. Seventy middle school students participated in the study and they were, firstly, evaluated with M-ABC-II test in order to be assigned in four groups. The yoga-experimental group with probable Developmental Coordination Disorder (p-DCD Yoga), (N=8), the yoga experimental group with typical motor coordination (TMC Yoga), (N=8) and the two control groups with p-DCD (N=8) and TMC (N=8). The intervention program lasted for 8 weeks and yoga sessions were held twice a week for 45 minutes each. Before and after these 8 weeks the students were tested with the ‘Sit and reach ‘ test and ‘Sit up test’ and only the p-DCD groups were evaluated with M-ABC-II test. The results of the present research showed that the intervention program had no statistically significant effect on the motor coordination of the adolescents with p-DCD (p>.05), but it had statistically significant (p
