Abstract

Abstract We give a silent self-stabilizing algorithm for the generalized minimal k-dominating set problem in a connected distributed network G. Given a positive integer k and two sets of processes R ⁎ ⊆ D ⁎ , the problem is to find a set D which is minimal subject to the conditions that R ⁎ ⊆ D ⊆ D ⁎ and that D is k -dominating relative to D ⁎ , meaning that every process within distance k of D ⁎ is also within distance k of D. The algorithm is order-invariant, requires O (log ⁡ N + log ⁡ k) space per process, works under the distributed unfair scheduler, and converges in O (N + k) rounds, where N is a given upper bound on the number of processes.

18. On probabilistic snap-stabilization.

Abstract

In this paper, we introduce probabilistic snap-stabilization . We relax the definition of deterministic snap-stabilization without compromising its safety guarantees. In an unsafe environment, a probabilistically snap-stabilizing algorithm satisfies its safety property immediately after the last fault; whereas its liveness property is only ensured with probability 1. We show that probabilistic snap-stabilization is more expressive than its deterministic counterpart. Indeed, we propose two probabilistic snap-stabilizing algorithms for a problem having no deterministic snap- or self-stabilizing solution: guaranteed service leader election in arbitrary anonymous networks. This problem consists in computing a correct answer to each process that initiates the question “Am I the leader of the network?,” i.e. , (1) processes always compute the same answer to that question and (2) exactly one process computes the answer true . Our solutions being probabilistically snap-stabilizing, the answers are only delivered within an almost surely finite time; however any delivered answer is correct, regardless the arbitrary initial configuration and provided the question has been properly started.

*SELF-stabilization (Computer science), *COMPUTER networks, *TOPOLOGICAL degree, *APPLICATION software, *DATA analysis
Abstract

In this paper, we give a distributed silent self-stabilizing algorithm, DISJ, for the disjunction problem in a connected network. In this problem, each process x has an input bit x . in , assigned by the application layer, and each process must compute the disjunction of the input bits of all processes. DISJ is uniform, and works in an anonymous network under the distributed unfair daemon. The stabilization time of DISJ is O ( n ) rounds, where n is the size of the network, and the memory requirement per process is O ( log ⁡ D + Δ ) where D and Δ are, respectively, the diameter, and the maximum degree of the network.

22. Certification of an exact worst-case self-stabilization time.

*DISTRIBUTED algorithms, *CERTIFICATION
Abstract

Unlike qualitative properties such as correctness (safety and liveness), quantitative properties of distributed algorithms have only been certified in very few studies. This work is the first attempt to certify time complexity bounds of a fault-tolerant distributed algorithm. Our case study consists in formally proving, using the Coq proof assistant, the time complexity of the first Dijkstra's self-stabilizing token ring algorithm. In more detail, we formally prove both the self-stabilization and exact worst-case stabilization time of this algorithm assuming asynchronous settings. This latter result is obtained in two main steps. First, we certify a non-trivial upper bound on the stabilization time, i.e. , every execution in an N -size ring contains at most 3 ⋅ N ⋅ (N − 1) 2 − N − 1 steps if N ≥ 4 , at most 3 steps if N = 3 ; and in remaining cases, the stabilization time is zero. Then, for each case, we exhibit a possible execution whose complexity exactly matches those upper bounds. Notice that the tight bounds for N = 3 and N ≥ 4 were unknown until now, even among self-stabilization researchers. • This work is the first attempt to certify the time complexity of a fault-tolerant distributed algorithm. • The case study consists in the worst case stabilization time in steps of the first self-stabilizing algorithm proposed by Dijkstra. • The complexity analysis is complete: we certify the exact worst case stabilization time in steps of the algorithm.

Abstract

YBCO coated conductors have very large critical current density and the field distribution in a transformer is favourable to obtain tapes with low ac losses. The objective of the READY European project is the construction of a transformer that uses first lengths of YBCO tapes produced by some of the partners. The secondary winding will use a YBCO conductor (limited length), the primary will use a PIT Bi2223 tape. We chose a cold magnetic circuit with low iron loss sheets. The cryostat is then very simple with metallic vessels and only one interface with the pulsed tube is required. Helium is the coolant fluid since a wide range of operating temperatures (40–80 K) is foreseen. The transformer design and optimisation will be presented as well as preliminary experiments (He cooling, ac loss measurements, inrush current PIT behaviour,…) to validate some chosen solutions and theoretical calculations.

Abstract

Abstract: The purpose of this work was to describe and discuss the fundamental issues involved in reactive brazing of alumina to copper by CuAgTi alloys. The method used to bring the Ti to the CuAg braze enabled the Ti concentration in the braze to be varied to a large extent (from 0.8 to 6wt.%). It was then possible to study the effects of this parameter on the interfacial chemistry and joint microstructure, as well as on the mechanical performance of the brazing joints, characterized by tensile tests. The mechanical strength of metal/alumina joints processed by reactive brazing was also compared with data obtained using a standard metallization process. [Copyright &y& Elsevier]

Abstract

Abstract: Objectives. – Analysis of our experience and propositions on the diagnosis and treatment of congenital bronchopulmonary malformations (BPM). Population and methods. – Retrospective study of BPM diagnosed between 1997 and 2001. Analysis of clinical spectrum, diagnosis tools, treatment, and clinical outcome. Results. – Thirty-two cases of BPM have been investigated (11 cystic adenomatoid malformations, 7 pulmonary sequestrations, 7 bronchogenic cysts, 4 congenital lobar emphysema, and 3 complex emphysematous malformations). Nineteen patients had a prenatal diagnosis. For 9 others, symptoms occurred before 4 years of age. Evaluation included a CT-scan in all patients (BPM involution in one). Surgical treatment was performed in 30 patients (lobectomy in 18), with a mean age of 7 months for asymptomatic patients. During the follow-up (mean: 3 years), respiratory symptoms were reported in 10 cases, 3 of them were related to the BPM. Discussion. – Improvement in prenatal ultrasound diagnosis modified the management strategy. Considering the risk of pulmonary complications, surgical treatment is required during the first months of life. For congenital lobar emphysema, and some pulmonary sequestrations or small cystic adenomatoid malformations (<3 cm), conservative attitude may be preferred. BPM justify a multidisciplinary management. [Copyright &y& Elsevier]

Abstract

The φ-meson production cross section is measured for the first time at a sub-threshold energy of 1.93 A GeV in 58Ni+58Ni central collisions. The φ data were obtained within the acceptance of the CDC/Barrel subsystem of FOPI. For a sample of 4.7×106 central events, after background subtraction, 23 candidates were observed. Extensive GEANT simulations of the detector performance are shown in a thorough comparison to the real response, aiming at a good understanding of the apparatus and at a trustable determination of the efficiencies, production probability and possible systematic errors. A filter procedure is elaborated, which is meant to facilitate the comparison of any theoretical calculation or new data with the current ones. How to extrapolate the present value to a φ-meson cross section in 4π is also discussed. This result on pseudo-vector mesons can now be compared to existing experimental knowledge for the same reaction at the same incident energy for various outgoing channels, K+ and K− included. A significant fraction (at least 20%) of the K−-mesons is originating in the decay of the φ, supporting the statement that the two channels are strongly correlated. [Copyright &y& Elsevier]

Abstract

We present pulse height measurements in drift chambers operated with Xe,CO2 gas mixtures. We investigate the attachment of primary electrons on oxygen and SF6 contaminants in the detection gas. The measurements are compared with simulations of properties of drifting electrons. We present two methods to check the gas quality: gas chromatography and 55Fe pulse height measurements using monitor detectors. [Copyright &y& Elsevier]

34. Thermal effects in YBCO/metal bilayers at high current densities

Abstract

We report on the thermal aspects associated with the switching properties at high current densities of YBCO thin films shunted by a metallic layer. The role of the shunt is first detailed in a current ramp mode experiment under various conditions of temperature and magnetic field. We discuss specifically a regime associated with an almost total current diversion by the metallic layer, observed when the critical current density is reduced at temperatures close to the critical temperature Tc or under magnetic field. This regime is associated to a thermal anomaly, as seen in the temperature signal measured on the rear side of the substrate, which can explain the partial recovery of the superconductive state under magnetic field. Under current limitation conditions at 50 Hz, 77 K and self-field, the temperature reaches 260 K at the rear side of the sapphire substrate after 0.4 s without any damage to the superconducting device.
