Adaptive Stochastic Airline Seat Inventory Control under Parametric Uncertainty
2013
Airline seat inventory control is a very profitable tool in the airline industry. The problem of adaptive stochastic airline seat inventory control lies at the heart of airline revenue management. This problem concerns the allocation of the finite seat inventory to the stochastic customer demand that occurs over time before the flight is scheduled to depart. The objective is to find the right combination of customers of various fare classes on the flight such that revenue is maximized. In this paper, the static and dynamic policies of stochastic airline seat inventory control (airline booking) are developed under parametric uncertainty of underlying models, which are not necessarily alterna…
Method to Define User Interfaces in the Requirements Analysis Phase
2018
Many requirements for quality in use are elicited in the late development phase. However, if requirements are elicited in the late development phase, the development may return to the previous phase or some requirements cannot be realized due to costs and schedules. To reduce these cases, we propose a method to elicit the requirements in the requirements analysis phase. First, software developers analyze the user characteristics (UCs) of the target users and specify important quality characteristics (QCs) for quality in use and UI design items based on the relationships among UC, QC, and UI design items. Because UI design items are considerations to develop UIs, the specified UI design item…
Steiner systems and configurations of points
2020
AbstractThe aim of this paper is to make a connection between design theory and algebraic geometry/commutative algebra. In particular, given any Steiner SystemS(t, n, v) we associate two ideals, in a suitable polynomial ring, defining a Steiner configuration of points and its Complement. We focus on the latter, studying its homological invariants, such as Hilbert Function and Betti numbers. We also study symbolic and regular powers associated to the ideal defining a Complement of a Steiner configuration of points, finding its Waldschmidt constant, regularity, bounds on its resurgence and asymptotic resurgence. We also compute the parameters of linear codes associated to any Steiner configur…
Eye tracking and the translation process: reflections on the analysis and interpretation of eye-tracking data
2014
Eye tracking has become increasingly popular as a quantitative research method in translation research. This paper discusses some of the major methodological issues involved in the use of eye tracking in translation research. It focuses specifically on challenges in the analysis and interpretation of eye-tracking data as reflections of cognitive processes during translation. Four types of methodological issues are discussed in the paper. The first part discusses the preparatory steps that precede the actual recording of eye-tracking data. The second part examines critically the general assumptions linking eye movements to cognitive processing in the context of translation research. The thir…
Rhythmic and textural musical sequences differently influence syntax and semantic processing in children.
2020
International audience; Effects of music on language processing have been reported separately for syntax and for semantics. Previous studies have shown that regular musical rhythms can facilitate syntax processing and that semantic features of musical excerpts can inZluence semantic processing of words. It remains unclear whether musical parameters, such as rhythm and sound texture, may speciZically inZluence different components of linguistic processing. In the current study, two types of musical sequences (one focusing on rhythm and the other focusing on sound texture) were presented to children who were requested to perform a syntax or a semantic task thereafter. The results revealed tha…
The disclosure paradox: how persuasion knowledge mediates disclosure effects in sponsored media content
2020
Persuasion knowledge is an established construct in the explanation of recipients’ coping with persuasive communication. It gains particular importance when persuasion attempts are covert. This is ...

Field-induced slow relaxation of magnetisation in an anionic heterotetranuclear [ZnIIReIV3] system
2019
The compound (NBu4)4[ZnII{ReIVCl4(μ-ox)}3] (1) [NBu4+ = tetra-n-butylammonium cation and ox2− = oxalate dianion] is the first example of an oxalato-bridged ZnII system coordinated to a 5d metal ion that exhibits slow relaxation of magnetisation.
ELECTRON-PHONON COUPLING IN HEAVILY DOPED SILICON
2001
The coupling constant in electron-phonon interaction is a very important issue in nanoscale applications. We have measured this constant in heavily doped silicon. Electron-phonon interaction is proportional to T6 and the coupling constant is found to be 1.5 × 108 W/K5m³, which is about one tenth of the value in normal metals.
A fast heuristic for solving the D1EC coloring problem
2010
In this paper we propose an efficient heuristic for solving the Distance-1 Edge Coloring problem (D1EC) for the on-the-fly assignment of orthogonal wireless channels in wireless as soon as a topology change occurs. The coloring algorithm exploits the simulated annealing paradigm, i.e., a generalization of Monte Carlo methods for solving combinatorial problems. We show that the simulated annealing-based coloring converges fast to a sub optimal coloring scheme even for the case of dynamic channel allocation. However, a stateful implementation of the D1EC scheme is needed in order to speed-up the network coloring upon topology changes. In fact, a stateful D1EC reduces the algorithm’s convergen…
