Engaging and motivating students is always a challenge particularly when teaching subjects that do not have a high practical content. In this situation it was also necessary to present an overview of the subject to be studied while at the same time introduce new members to the existing class. The XP Game is a simple and interactive set of activities that simulates the eXtreme Programming (XP) d...

We present a Simplex-type algorithm, that is, an algorithm that moves from one extreme point of the infinite-dimensional feasible region to another not necessarily adjacent extreme point, for solving a class of linear programs with countably infinite variables and constraints. Each iteration of this method can be implemented in finite time, while the solution values converge to the optimal valu...

The Extreme Programming software development methodology relies heavily on the colocation of the team members. Outsourcing and teleworking is becoming more common nowadays, meaning that XP practitioners need to adapt their daily XP practices for a distributed setting. In most cases the distributed teams use (existing) tools that is a direct translation of a practice without thinking about inter...

an increase, even moderate, in global temperature is expected to result in a change in frequency of extreme weather events like drought, heavy rainfall and storms. the study of extreme events is difficult due to the fact that it is difficult to find long-term homogeneous data series. also the delimitation of extreme events is not univocal since a parameter value that would be defined as an extr...

in present paper, a numerical analysis for a rectangular cavity filled with a anisotropic porous media has been studied. it is assumed that the horizontal walls are adiabatic and impermeable, while the side walls of the cavity are maintained at constant temperatures and concentrations. the buoyancy force that induced the fluid motion are assumed to be cooperative. in the two extreme cases of he...
