Computing closed form solutions of integrable connections

Proceedings of the 37th International Symposium on Symbolic and Algebraic Computation, 2012
We present algorithms for computing rational and hyperexponential solutions of linear D-finite partial differential systems written as integrable connections. We show that these types of solutions can be computed recursively by adapting existing algorithms handling ordinary linear differential systems.

Closed‐Form Heave Solutions for Expansive Soils

Journal of Geotechnical Engineering, 1988
During the past decade, the theory for heave prediction has developed within the context of unsaturated soil behavior and has become a valuable tool for geotechnical practice. The laboratory procedures for testing expansive soils have also been essentially standardized.

Closed-form solutions for vehicle traction problems

Proceedings of the Institution of Mechanical Engineers, Part D: Journal of Automobile Engineering, 2002
Conventional approaches to vehicle traction and propulsion analysis have used spread-sheets or numerical integrations owing to the difficulty in deriving closed-form solutions. This is inconvenient if a parameter is to be varied, and it is even more difficult when multiple parameters of a complex model are evaluated at the design ...

Closed-Form Solutions for Robust Inventory Management

Management Science, 2017
We propose and analyze robust optimization models of an inventory management problem, where cumulative purchase, inventory, and shortage costs over n periods are minimized for correlated nonidentically distributed demand. We assume that the means and covariance matrix of stochastic demand are known; the distributions are not needed.

Some Closed‐Form Solutions of Burgers’ Equation

Studies in Applied Mathematics, 1993
This paper shows how to use the method of quasisolutions to construct exact solutions to Burgers’ equation. A function υ=υ(x, y) is called a quasisolution of a PDE in case there exists a function φ (not a constant function) of one variable so that u(x, y)=φ(υ(x, y)) is a solution of the equation.

Closed-Form and Near Closed-Form Solutions for TDOA-Based Joint Source and Sensor Localization

IEEE Transactions on Signal Processing, 2016
In this paper, we derive closed-form and near closed-form solutions for joint source and sensor localization from time-difference-of-arrival (TDOA) measurements. In our previous works, we derived closed-form and near closed-form solutions for joint source and sensor localization from time-of-arrival (TOA) measurements. On the basis of these results,

Unbiased Closed-Form Solutions for Center of Rotation

2010
We present a fast closed form solution for estimating the exact joint locations inside the human body from motion capture data. The closed-form solution is robust, fast and unbiased. For example, the formulae are as much as 100 times faster than the traditional non-linear Maximum Likelihood Estimator and about 10 times faster than linear least squares ...

Alongwind Response Estimation: Closed Form Solution

Journal of the Structural Division, 1982
The problem of dynamic alongwind response of structures to forces induced by atmospheric turbulence is treated in this paper. Starting from the classical formulation, the study analyses the behaviour of two structural standard models, called point-like and threedimensional, respectively.

A closed form solution for ballistic vehicle motion

5th Atmospheric Flight Mechanics Conference for Future Space Systems, 1979
A closed-form solution is developed for the motion of a ballistic vehicle entering the atmosphere over a flat nonrotating Earth. The Alien and Eggers approach of using an exponential atmosphere is retained; however, the vehicle drag coefficient is expressed as a function of velocity instead of being considered a constant.

A Closed-form Solution for a Model of Precautionay Saving

The Review of Economic Studies, 1993
Summary: This paper analyses life-cycle consumption plans and distinguishes between temporal risk aversion and intertemporal substitution. The results assume that felicity functions are quadratic and that income follows a linear model with normally distributed errors.
