Starting with the Navier-Stokes equations, a system of equations is obtained to describe quasi-one-dimensional behavior of fluid in a compliant tube. The nonlinear terms which cannot be shown to be small in the original equations are retained, and the resulting equations are nonlinear. A functional pressure-area relationship is postulated and the final set of equations are quasi-linear and hyperbolic, with two independent and two dependent variables. A method of numerical solution of the set of equations is indicated, and the application to cases of interest is discussed.

One of the fundamental problems of theoretical electrocardiology is to determine the potential distribution on the surface of the torso due to the time-varying dipolar heart source. In this paper we present a rigorous derivation of the integro-differential equations for the potential, containing, for the first time, the effects of the time dependence of the source and the dielectric properties of the medium. These equations provide a general and rigorous basis from which to attack the problem numerically on a computer and permit the use of a detailed model of the thorax as a multiple region volume of different dielectric and conducting properties.

Software project management probably is a sector that has witnessed the highest rate of project failure in the world. This is not the case with project management concerned with other disciplines due to better management of their inherent strengths and weaknesses.Hard skills, often described as a science and comprising processes, tools and techniques applied to projects are the main focus of many project management methodologies. Extensive research has been carried out in the project management domain with greater focus on hard skills. Soft skills described as an art, are very often ignored during software project management. Such skills, acquired through experience, are concerned with managing and working with people, ensuring customer satisfaction and creating a conducive environment for the project team to deliver high quality products within budget and on time and exceeding stakeholder expectations. This paper summarizes the soft skills that can possibly improve the success rate of software projects. These projects, if not managed properly can lead to escalation of budget and time schedules beyond expectations. Deterioration of quality may be inevitable while deploying efforts to deal with cost overrun and schedule extension.Research in the field of soft skills required has been carried out at the University of Arkansas. The results show that IT organizations are conscious of the need for soft skills. Furthermore, a number of organizations, like Polaris, Sun Microsystems and Mastek have found it necessary to include soft skills in their training agenda.
