Foley Catheter Characteristics: Predicting Problems

Journal of Endourology, 2009
To evaluate the physical properties of urethral catheters that are predictive of ease of placement and risk of urethral trauma: Stiffness, buckling, and friction forces.Eleven Bard Lubri-Sil and 10 Kendall Dover 16F Foley catheters were tested using a linear motion stage driven by a stepper motor with a resolution of 5 microns/step or by hand.

Asian Megacity Characteristics, Problems, and Policies

International Regional Science Review, 1989
Using ten Asian megacities as examples, this article discusses a range of megacity characteristics and problems, including population growth, economic structure, spatial strategies, land policy, urban service provision, institutional development, and managerial problems.

A Spectral Method of Characteristics for Hyperbolic Problems

SIAM Journal on Numerical Analysis, 1991
A spectral method is combined with a timestepping along the characteristics for numerical solution of first-order hyperbolic equations. Theorems about stability and convergence are proved. Numerical examples for one- and two-dimensional problems are given.

Solution of Characteristic Problems

2011
The main objective of the analysis presented in this chapter consists in finding solutions allowing calculating the factor of conjugation (FC), whose definition is given by (2.13)[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15]. After substitution of the equations for the temperature oscillations (2.9a), (2.9b) together with (2.11) for the THTC in ...

THE CHARACTERISTIC PROBLEM FOR THE EINSTEIN VACUUM EQUATIONS

Asymptotic Methods in Nonlinear Wave Phenomena, 2007
We show how to prescribe the initial data of a characteristic problem satisfying the costraints, the smallness, the regularity and the asymptotic decay suitable to prove a global existence result. In this paper, the firstof two, we show in detail the construction of the initial data and give a sketch of the existence result.

Diagnostic Characteristics and Problems

1981
This chapter attempts to diagnose or analyse those features or factors which have made it possible for the developed countries to become developed and then to show that, in spite of their power, prosperity and cultural leadership, they have not been able to escape entirely serious difficulties and national problems.

Use of characteristic modes in multiple-scattering problems

Journal of Physics D: Applied Physics, 1995
It is proposed that a convenient choice of basis functions for applying the moment method to the analysis of scattering and/or mutual coupling between metallic bodies impinged upon by an electromagnetic field is that of the characteristic modes of a single scatterer.

Characteristics of Dynamic Problems

1996
Abstract There are a variety of problems where the behaviour of soils in dynamic loading is of concern, but because of diversity in the areas and complexity in the conditions under which dynamic loads are applied, it is not easy to establish a hierarchy in the discipline and to put all problems in a proper perspective.

Characteristics of Problem Instances

1998
The requests on algorithms applicable in VLSI CAD differ from other areas. This also influences the design of EA based tools. For this, in this chapter some important aspects are highlighted that have to be considered.

Differential Inequalities and Characteristic Value Problems

SIAM Review, 1976
Sturm–Liouville problems are discussed under hypotheses too weak to guarantee uniqueness of solutions of the related initial value problems. The results include sharp upper and lower bounds for the nth characteristic value, a simple procedure for deducing existence of the nth characteristic function from its existence on subintervals for $n = 1$, a ...
