Critical analysis of the spin-rotation constants of CF2 and CCl2: A theoretical investigation
2005
Quantum chemical ab initio calculations for the spin-rotation constants of difluorocarbene (CF2) and dichlorocarbene (CCl2) were carried out using coupled-cluster techniques with sequences of correlation-consistent basis sets. Theoretical best estimates were obtained using extrapolation to the complete basis-set limit and taking into account corrections for core correlation, additional diffuse functions and zero-point vibrational effects. It is demonstrated that such accurate theoretical estimates can be used either to support or to challenge the analysis of the experimental spectra and the reliability of the resulting data. 2005 Elsevier B.V.

The review of internet marketing use in Latvia's companies
2017
Development of new technologies and increasing competition require new solutions in business applications in internet marketing and advertising. The paper deals with issues related to advertising activities in internet marketing. There were presented both theoretical findings and empirical analysis of the survey conducted among Latvia's companies. The survey was carried out with the assistance of telemarketing company (telephone interviews) among companies selected from Register of Enterprises LURSOFT. The analysis of survey results compared companies responses depending on the company size and turnover changes during the last three years. Various statistical indicators were used for this a…
Hands On: incorporación de data sprints y digital methods en la docencia de marketing digital
2022
Este artículo recopila la experiencia acumulada durante 9 años en el diseño y ejecución de data sprints en el marco del Máster en Comunicación y Marketing Digital de la Universitat Autònoma de Barcelona. Con más de 90 proyectos distintos a sus espaldas, estas jornadas han sido un punto de encuentro para profesionales, académicos y estudiantes, posibilitando el intercambio de conocimiento y la transferencia de técnicas entre métodos de investigación del ámbito académico con la investigación aplicada al marketing digital. Al mismo tiempo, el formato data sprint facilita el conocimiento práctico y la adquisición de competencias comunicativas, organizativas y el proceso de resolución de problem…
Simulations of non-spherical particles suspended in a shear flow
2000
The lattice-Boltzmann method was used to investigate the effects of the shape and concentration of the particles on the rheological properties of non-Brownian suspensions for non-zero Reynolds numbers. Several case studies were analyzed and the methods used were found to give accurate predictions for these systems. The viscosity of suspensions of both spherical and non-spherical particles was determined as functions of shear rate and concentration of particles. It was shown that, for high shear rates, shear thickening appears. This phenomenon is particularly pronounced for particles of irregular shape.
Experimental and theoretical studies of Λ doublings and permanent electric dipoles in the low-lying Π1 states of NaCs
2006
We present experimental data on the electric permanent dipole moments d(v',J') and lambda splittings (q factors) in the quasidegenerate (3) 1pi(e/f) state of the NaCs molecule over a wide range of the vibrational (v') and rotational (J') quantum numbers by using the combination of dc Stark mixing and electric radio frequency-optical double resonance methods. Within the experimental (3) 1pi state v' ranged from v' = 0 to 34, q values exhibited a pronounced decrease from 7.91x10(-6) to 0.47x10(-6) cm(-1), while absolute value(d) values varied between 8.0 and 5.0 D. Experimental evaluation yielded small d values about 1 D for D2 1pi state v'3 levels. The experiment is supported by ab initio el…
Ab initio calculations for the far infrared collision induced absorption by N2 gas
2014
We present (far-infrared) Collision Induced Absorption (CIA) spectra calculations for pure gaseous N2 made for the first time, from first-principles. They were carried out using classical molecular dynamics simulations based on ab initio predictions of both the intermolecular potential and the induced-dipole moment. These calculations reproduce satisfactory well the experimental values (intensity and band profile) with agreement within 3% at 149 K. With respect to results obtained with only the long range (asymptotic) dipole moment (DM), including the short range overlap contribution improves the band intensity and profile at 149 K, but it deteriorates them at 296 K. The results show that t…
A model for managing and evaluating solar radiation for indoor thermal comfort
2007
Thermal comfort of people occupying indoor spaces depends, to a large extent, on the direct component of solar radiation incident on the human body. In turn, even the diffuse component of the solar radiation could affect the thermal sensations of people. Despite this evidence, at the present there is a lack in the availability of simple and reliable methods capable of taking into account the influence of the solar radiation on thermal balance in the human body. In this work a comprehensive method is presented for the computation of the mean radiant temperature of people in thermal moderate indoor environments in the presence of solar radiation. The effects produced on the amount of solar ra…
Triple solutions for nonlinear elliptic problems driven by a non-homogeneous operator
2020
Abstract Some multiplicity results for a parametric nonlinear Dirichlet problem involving a nonhomogeneous differential operator of p -Laplacian type are given. Via variational methods, the article furnishes new contributions and completes some previous results obtained for problems considering other types of differential operators and/or nonlinear terms satisfying different asymptotic conditions.
