Mathematica Bohemica, 1994 Summary: The problem of integrating factor for ordinary differential equations is investigated. Conditions are given which guarantee that each solution of \(\partial_ 1 F(x,y) + y'\partial_ 2 F(x,y) = 0\) is also a solution of \(M(x,y)+ y' N(x, y)= 0\) where \(\partial_ 1 F= \mu M\) and \(\partial_ 2 F= \mu N\).

Darboux integrability and the inverse integrating factor
Journal of Differential Equations, 2003 Consider planar (real or complex) polynomial vector fields \(X=P(x,y)\partial_x+Q(x,y)\partial_y\) having a Darboux first integral of the form \[ H= f_1^{\lambda_1}\cdots f_p^{\lambda_p} \left( \exp\left( {h_1}\over {g_1} \right) \right)^{\mu_1} \cdots \left( \exp\left({h_q}\over{g_q} \right) \right)^{\mu_q}, \] where \(f_i, g_i\) and \(h_i\) are ...

Analytic Methods for Solving Higher Order Ordinary Differential Equations
Mathematics, 2019 In this work, an analytic approach for solving higher order ordinary differential equations (ODEs) is developed. The techniques offer analytic flexibility in many research areas such as physics, engineering, and applied sciences and are effective for ...

The Poincaré map of degenerate monodromic singularities with Puiseux inverse integrating factor
Advances in Nonlinear Analysis, 2023 We consider analytic families of planar vector fields depending analytically on the parameters in Λ\Lambda that guarantee the existence of a (may be degenerate and with characteristic directions) monodromic singularity.

Automatic Rate and Rate-Integrating Mode-Switchable Axisymmetric Gyroscope
Sensors, 2022 This paper describes a novel rate and rate-integrating mode-switchable axisymmetric gyroscope. A precession angle tracking algorithm is developed to enable the gyro to switch automatically between rate and rate-integrating modes at preset rate points ...

The Social Justice as Factor, Integrating Migrants into Local Community
Социологическая наука и социальная практика, 2016 Not only has social justice retained its relevance in the eyes of modern Russians, but it has also become one of their key personal values. The general notion of social justice creates a feeling of solidarity in the community, while also fostering an ...

Piecemeal Versus Precipitous Factor Market Integration [PDF]
International Economic Review, 1995 Summary: The effects of the speed of international factor markets integration are studied within a general equilibrium, two country model. It is shown that even in the absence of economic frictions there can be no theoretical presumption regarding the ``optimal'' speed of integration.

Computing Bayes Factors Using Thermodynamic Integration [PDF]
Systematic Biology, 2006 In the Bayesian paradigm, a common method for comparing two models is to compute the Bayes factor, defined as the ratio of their respective marginal likelihoods. In recent phylogenetic works, the numerical evaluation of marginal likelihoods has often been performed using the harmonic mean estimation procedure.
