Computer aided scheduling and routing of vehicle-carrier fleet—a case study

2016

This paper presents a case study of development of an information system for a large enterprise from vehicle-transport industry. A novel optimization model and algorithms developed to solve scheduling and routing of vehicle-carrier fleet are presented and discussed. Carried out qualitative experiments confirmed the usability of developed user-guided search paradigm and high performance of autonomous algorithmic solution search methods.

Time - frequency analysis in an open - air theater

2005

Acoustics measurements have been carried out along the steps of an ancient open-air theater. Source positions were fixed in several points in the orchestra while microphones, radially placed, were rotated sector by sector, spatially sampling the cavea. Measurements analysis allowed some speech and music sound quality index calculation for each source-microphone couple. Moving from the observation of acoustic quality indexes a time-frequency analysis of impulse response is presented in this paper. Timefrequency analysis of impulse response gives hints for new considerations about the sound field in this peculiar environment.

Le renouvellement du contrôle juridictionnel de l’administration au moyen du recours pour excès de pouvoir

2017

The role of the administrative judge (the excess of power) has evolved due to the implementation of the various texts adopted recently as well as the developments in the case-law in recent years. In many areas, its role now goes beyond the mere confrontation of an administrative act with the rule of law. At the heart of the annulment decision is a statement and an assessment of the facts, apart from the interpretation of the law, which were usually separated by the principle of separation between the administration and its judge.Some jurisprudence which has become very classical, as well as others more recent, can be considered as characteristic manifestations of this new tendency of the ju…

A Time-Non-Homogeneous Double-Ended Queue with Failures and Repairs and Its Continuous Approximation

2018

We consider a time-non-homogeneous double-ended queue subject to catastrophes and repairs. The catastrophes occur according to a non-homogeneous Poisson process and lead the system into a state of failure. Instantaneously, the system is put under repair, such that repair time is governed by a time-varying intensity function. We analyze the transient and the asymptotic behavior of the queueing system. Moreover, we derive a heavy-traffic approximation that allows approximating the state of the systems by a time-non-homogeneous Wiener process subject to jumps to a spurious state (due to catastrophes) and random returns to the zero state (due to repairs). Special attention is devoted to the cas…

Structural distortions in homoleptic (RE)4A (E = O, S, Se; A = C, Si, Ge, Sn): Implications for the CVD of tin sulfides

2001

The structures of Sn(SBut)4 and Sn(SCy)4 have been determined and adopt S4 and D2 conformations respectively; the anion [(PhS)Sn3]−, as its Ph4P+ salt, has a structure approaching Cs symmetry. In all three compounds, there are large variations in the ∠S–Sn–S within the same molecule, which have been rationalised in terms of the C–S–Sn–S–C conformations. For Sn(SR)4, the ∠S–Sn–S increases as the conformations change from trans, trans to trans, gauche and gauche, gauche, as the number of eclipsed lone pairs decreases and this rationale is shown to be applicable to a variety of A(ER)4 (A = C, Si, Ge, Sn; E = O, S, Se) and related [Mo(SR)4, Ga(SR)4−] systems. AM1 calculations have been used to …

Sémiotique du goût et de la sensibilité alimentaire

2021

L'alimentation en général et le goût, en particulier, bénéficient d'une large couverture disciplinaire. Sans parler des sciences expérimentales, les sciences humaines et sociales ont exploré, sous toutes les facettes,le capital de signification de ce domaine si intimement lié au vivant, à l'existence,à l'expérience. La sémiotique, au plus près des signes et des significations, ne pouvait manquer un terrain aussi riche et complexe pour se mettre à l'épreuve.La sémiosphère alimentaire est abordée à travers l'articulation de ses différents plans d'analyse, comme autant d'espaces figuratifs en communication : auto (saveurs et sensations) ; micro (commensalité et convivialité) ; méso (régimes mé…

Burnout syndrome assessment among Spanish oral surgery consultants: A two populations comparative pilot study.

2021

Background The professional Burnout Syndrome (BOS) or Burnout is considered a professional disease made up of three interrelated dimensions (emotional exhaustion, depersonalization and lack of personal fulfillment). BOS has been documented to most severely affect the healthcare professions, especially dentists. On the other hand, its appearance has been documented at an early age, during dental training. However, there are no studies that analyze its incidence in professionals dedicated to Oral Surgery and Implantology, determining the age of onset and related factors. Material and Methods The modified Maslach questionnaire was carried out anonymously among the professors and students of th…
