Multiple cylinder UTD solution

Electronics Letters, 2005
The uniform theory of diffraction (UTD) is extended to multiple cylinder structures by introducing a new formulation of the UTD diffraction coefficients in cooperation with a slope diffraction term for maximum accuracy in the electromagnetic modelling. The solution is, then, applicable to radiowave paths where mountains, hills or other rounded objects ...

Finding Multiple Solutions in Nonlinear Integer Programming with Algebraic Test-Sets [PDF]

, 2018
We explain how to compute all the solutions of a nonlinear integer problem using the algebraic test-sets associated to a suitable linear subproblem. These test-sets are obtained using Gröbner bases. The main advantage of this method, compared to other

Incidence and Outcome of Infants With Cancer in Canada: A Report From Cancer in Young People in Canada Database

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Purpose Infants with cancer are rare and face unique challenges. Our study aims to describe the incidence of infantile cancers in Canada and to compare treatment‐related mortality (TRM) and their outcomes with those of older children. Methods We conducted a retrospective cohort study using the Cancer in Young People in Canada database ...

On Different Type Solutions of Boundary Value Problems

Mathematical Modelling and Analysis, 2016
We consider boundary value problems of the type x'' = f(t, x, x'), (∗) x(a) = A, x(b) = B. A solution ξ(t) of the above BVP is said to be of type i if a solution y(t) of the respective equation of variations y'' = fx(t, ξ(t), ξ' (t))y + fx' (t, ξ(t), ξ' (

Multiple solutions for a class of BVPs of fractional discontinuous differential equations with impulses

AIMS Mathematics, 2023
In this paper, we mainly study the following boundary value problems of fractional discontinuous differential equations with impulses: $ \hskip 3mm \left\{ \begin{array}{lll} _{t}^{C} \mathcal {D}^{\mathfrak{R}}_{0^{+}}\Lambda(t) = \mathcal {E}(t ...

Safety and Efficacy of Anticoagulation Therapy in Paediatric Patients With Solid Tumours or Lymphomas at Risk of Thrombocytopenia: A Retrospective Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Patients with solid tumours or lymphomas have an increased risk of thromboembolism (TE) and thrombocytopenia. Evidence‐based strategies for anticoagulation therapy (ACT) for patients with thrombocytopenia are limited. We examined the impact of thrombocytopenia on ACT administration and bleeding incidence in children with solid ...

Multiple solutions to a class of inclusion problems with operator involving p(x)-Laplacian

Electronic Journal of Qualitative Theory of Differential Equations, 2013
In this paper, we prove the existence of at least two nontrivial solutions for a nonlinear elliptic problem involving p(x)-Laplacian-like operator and nonsmooth potentials.

Coupled KdV equations derived from atmospherical dynamics

, 2005
Some types of coupled Korteweg de-Vries (KdV) equations are derived from an atmospheric dynamical system. In the derivation procedure, an unreasonable $y$-average trick (which is usually adopted in literature) is removed.

Multiple positive solutions of parabolic systems with nonlinear, nonlocal initial conditions [PDF]

, 2016
In this paper we study the existence, localization and multiplicity of positive solutions for parabolic systems with nonlocal initial conditions. In order to do this, we extend an abstract theory that was recently developed by the authors jointly with ...
