Orthogonal-Based Second Order Hybrid Initial Value Problem Solver
This work focuses on development of an initial value problem solver by employing a new class of orthogonal polynomial, the basis function. We present the recursive formula of the class of polynomials constructed and adopt collocation technique to ...

Initial-value problems and signature change [PDF]
We make a rigorous study of classical field equations on a 2-dimensional signature changing spacetime using the techniques of operator theory. Boundary conditions at the surface of signature change are determined by forming self-adjoint extensions of the Schr dinger Hamiltonian.

Runge–Kutta Embedded Methods of Orders 8(7) for Use in Quadruple Precision Computations
High algebraic order Runge–Kutta embedded methods are commonly used when stringent tolerances are demanded. Traditionally, various criteria are satisfied while constructing these methods for application in double precision arithmetic.

Initial value problem for magnetic fields in heavy ion collisions [PDF]
When quark-gluon plasma emerges in the wake of a heavy-ion collision, magnetic field created by the valence charges has already permitted the entire interaction region.

The initial-boundary value problem for the biharmonic Schrödinger equation on the half-line [PDF]
We study the local and global wellposedness of the initial-boundary value problem for the biharmonic Schr\"odinger equation on the half-line with inhomogeneous Dirichlet-Neumann boundary data. First, we obtain a representation formula for the solution of

Fuzzy initial value problem [PDF]
In this paper, we present the fuzzy solution concept of the initial value problem. After introducing a metric between two fuzzy vectors, we prove that the system of fuzzy equations has unique solution under some condition.

Multiple sclerosis clinical decision support system based on projection to reference datasets
Abstract Objective Multiple sclerosis (MS) is a multifactorial disease with increasingly complicated management. Our objective is to use on‐demand computational power to address the challenges of dynamically managing MS. Methods A phase 3 clinical trial data (NCT00906399) were used to contextualize the medication efficacy of peg‐interferon beta‐1a vs ...
