A summary of the technical advances that are incorporated in fourth major release Q-Chem quantum chemistry program is provided, covering approximately last seven years. These include developments density functional theory methods and algorithms, nuclear magnetic resonance (NMR) property evaluation, coupled cluster perturbation theories, for electronically excited open-shell species, tools treating extended environments, algorithms walking on potential surfaces, analysis tools, energy...
This article summarizes technical advances contained in the fifth major release of Q-Chem quantum chemistry program package, covering developments since 2015. A comprehensive library exchange-correlation functionals, along with a suite correlated many-body methods, continues to be hallmark software. The methods include novel variants both coupled-cluster and configuration-interaction approaches based on algebraic diagrammatic construction variational reduced density-matrix methods. Methods...
We report an implementation of the spin-flip (SF) variant time-dependent density functional theory (TD-DFT) within Tamm-Dancoff approximation and non-collinear (NC) formalism for local, generalized gradient approximation, hybrid, range-separated functionals.

A consistently good observed Perdew-Burke-Ernzerhof (PBE) family,...
Abstract This paper provides an overview of the formal transformation between two complementary languages: OMG SysML™ and Modelica. SysML is a standardized general purpose graphical modeling language for capturing complex system descriptions in terms their structure, behavior, properties, requirements. Modelica systems analyzing continuous discrete time dynamics differential algebraic equations. Integrating descriptive power models with analytic computational capability that significantly...
In this paper, the operation principles of a traveling wave piezoelectric beam robot are presented. A prototype consisting an aluminum structure, with two non-collocated patches bonded on its surface, was fabricated and tested to demonstrate generation based one mode excitation for propulsion. numerical model developed used study optimize generated motion robot. Experimental characterization types has been carried out, comparison between them is made results given in paper.

The TWDPPR consists an aluminum structure with four noncollocated patches bonded on its surface. A two-dimensional modeling thin structures developed and validated in previous work used paper to model the based “two modes excitation” method propulsion. preliminary presented then verify generation 2-D motion. prototype fabricated forward, backward, steering motions...
A method to model dynamic hysteresis is proposed. The proposed based on an inverse Preisach with the magnetic flux density and its rate as inputs, field output. Assuming that hysteretic behavior does not depend history of this rate, distribution function expressed in terms rate. As a consequence, classical utilization rules triangle can be applied, thus making implementation very easy efficient. has been experimentally validated compared static model. Since inputs are easily implemented...

For given dimension, finite element model developed in previous work for structure verified experimentally here and then used determine optimal position. has been found that locating near ends will lead best performance,...
Giant magnetostrictive materials (GMM) can be integrated in actuator or sensor applications. The design of these systems is optimized based on a good knowledge the material properties and conditions use. Terfenol-D exhibits greatest room temperature strain among commercially available GMM, however, its magneto-elastic behavior very sensitive to pre-stress level. In this work, an experimental setup dedicated characterization GMM magneto-mechanical under constant stress described. A major...
Abstract In this paper we show how the Property‐Based Requirements (PBR) theory can be used to fully integrate Engineering (RE) into a Model‐Based Systems (MBSE) method using OMG UML and its SysML profile. The objective is avoid “in‐parallel” management of two distinct expressions same specification (or design): once in set textual requirements model, which must maintained consistent. This achieved by identification, common modeling concepts, Requirement Tracker Artifacts (RTA) that match...
Gradient-dependent approximations to the functional of kinetic energy non-interacting electrons (Ts[ρ]), which reflect various properties exact functional, are considered. For specially constructed pairs electron densities, for analytic expression differences Ts[ρ] is known, it shown that accuracy quantities derivable from a given approximation Ts[ρ]: and their derivatives, does not itself. The comparisons between values in such cases proposed as an independent condition/criterion appraisal Ts[ρ].
Composting is a natural dynamic biological process used to valorise putrescible organic matter. The composting can involve vigorous movements of waste material piles, which release high concentrations bioaerosols into the surrounding environment. There lack knowledge concerning dispersal airborne microorganisms emitted by plants (CP) as well potential occupational exposure workers. aim this study was investigate workers during working activities in three different types facilities (domestic,...

Based Kirchhoff-Love hypothesis, linear constitutive relations, plane stress formulation Hamilton principle, we have developed a 2D model for using the finite element method. It is not standard model, since calculation performed that does symmetries allow such easy assumptions. originality work use concept neutral to asymmetric 2D....
The dot intracule D(x) of a system gives the Wigner quasi-probability finding two its electrons with u·v = x, where u and v are interelectronic distance vectors in position momentum space, respectively. In this paper, we discuss show that Fourier transform d(k) can be obtained closed form for any whose wavefunction is expanded Gaussian basis set. We then invoke Parseval's theorem to our intracule-based correlation energy method into d(k)-based model requires, at most, one-dimensional quadrature.
