Mortgage valuation: a quasi-closed-form solution [PDF]
Quantitative Finance, 2012 Contingent claims mortgage valuation models tend to assume that the main drivers for the value of these financial assets are the risks of prepayment and default.

Polyaxial strength criterion and closed-form solution for squeezing rock conditions
Journal of Rock Mechanics and Geotechnical Engineering, 2020 In this paper, a nonlinear strength criterion is proposed using the average of intermediate (σ2) and minor (σ3) principal stresses in place of σ3 in Ramamurthy (1994)'s strength criterion.

A New Single-Logarithmic Approximation of Carson’s Ground-Return Impedances—Part 1
IEEE Access, 2021 Distributed energy resources with unbalanced phases increase the power imbalance in a grid, and compensating for the imbalance requires accurate knowledge of the impedance of the transmission and distribution lines.

A CLOSED-FORM SOLUTION FOR THE HEALTH CAPITAL MODEL [PDF]
Journal of Demographic Economics, 2014 Abstract:This paper provides a closed-form solution for the health capital model of health demand. The results are exploited in order to prove analytically the comparative dynamics of the model. Results are derived for the so-called pure investment model, the pure consumption model and a combination of both types of models.

Self-Collaborative Unsupervised Hashing for Large-Scale Image Retrieval
IEEE Access, 2022 Learning based hashing approaches have achieved considerable success in large-scale image retrieval due to the query effectiveness and efficiency. However, most studies highly rely on supervised knowledge like data labels, thus might fail in unsupervised

Closed-form shock solutions [PDF]
Journal of Fluid Mechanics, 2014 AbstractIt is shown here that a subset of the implicit analytical shock solutions discovered by Becker and by Johnson can be inverted, yielding several exact closed-form solutions of the one-dimensional compressible Navier–Stokes equations for an ideal gas. For a constant dynamic viscosity and thermal conductivity, and at particular values of the shock

A closed form solution for ac electo-kinetic-driven flow in a microchannel
Journal of Thermal Engineering, 2015 The electro-osmotic fully-developed flow in a circular microchannel was studied under an alternative electric field. An analytical approach based on the linearized poisson-Boltzmann equation was selected to obtain an exact solution of the electrical ...
