THE GENERATIONS` PREFERENCES FOR ONLINE TRAVEL BOOKING SYSTEMS AND TOOLS

Considering the changes brought by the development of mobile technologies and devices, both in the behavior and the preferences of individuals, as well as aspects related to the demographic evolution and the generational classification of the world population, a study was conducted to identify the generational preferences of tourists for the systems and tools used in the online travel booking; it was also considered that tourism is recognized as an adopting industry of all new mobile technologies and ITC solutions, but also being permanently adapted to the behavioral changes of tourists; this article contains, in the first part, a statistical picture on aspects related to the behavioral preferences of tourists according to their generation, and in the second part, the results of the study carried out; We believe the results obtained can provide important insights to the tourism industry, but also those in related industries and obviously for tourists

The Stabilizing Effect of Noise on the Dynamics of a Boolean Network

In this paper, we explore both numerically and analytically the robustness of a synchronous Boolean network governed by rule 126 of cellular automata. In particular, we explore whether or not the introduction of noise into the system has any discernable effect on the evolution of the system. This noise is introduced by changing the states of a given number of nodes in the system according to certain rules. New mathematical models are developed for this purpose. We use MATLAB to run the numerical simulations including iterations of the real system and the model, computation of Lyapunov exponents, and generation of bifurcation diagrams. We provide a more in-depth fixed-point analysis through analytic computations paired with a focus on bifurcations and delay plots to identify the possible attractors. We show that it is possible either to attenuate or to suppress entirely chaos through the introduction of noise and that the perturbed system may exhibit very different long-term behavior than that of the unperturbed system

8-(Diphenyl­phosphan­yl)quinoline

The title compound, C21H16NP, is a known P—N chelator and various crystal structures of its metal complexes have been reported. However, no crystallographic evidence of the free ligand has been given to date. The phenyl rings are almost orthogonal to one another [dihedral angle = 88.9 (1)°], and they are twisted from the mean plane of the quinoline by 80.5 (1) and 76.3 (1)°

Parameter Inference in the Pulmonary Circulation of Mice

This study focuses on parameter inference in a pulmonary blood cir- culation model for mice. It utilises a fluid dynamics network model that takes selected parameter values and aims to mimic features of the pulmonary haemody- namics under normal physiological and pathological conditions. This is of medical relevance as it allows monitoring of the progression of pulmonary hypertension. Constraint nonlinear optimization is successfully used to learn the parameter values

N 1,N 2-Bis­(2,6-di­methyl­phen­yl)-N 1-hydroxyformamidine N,N′-bis­(2,6-dimethyl­phen­yl)-N-oxidoformamidinium dichloro­methane solvate

The title compound, 2C17H20N2O·CH2Cl2, was obtained by N-oxidation of the parent formamidine with m-chloro-peroxy­benzoic acid (m-CPBA). This is the first use of the above-mentioned synthetic route for the preparation of hydroxy­amidines. The title compound crystallizes as a cyclic dimer resulting from the presence of O—H⋯O and N—H⋯N hydrogen bonds
