Requirements engineering is a core practice within eXtreme Programming. Practising teams learn to not abandon any of the interconnected core practices. The continuous feedback teaches the team that they will develop at a faster and more reliable pace with the full set of practices. This paper shares an experience of how teams could accelerate development out of necessity, while maintaining thei...

This paper presents an early empirical study on Extreme Programming practices employing a qualitative action research method. The study was conducted on university students doing real commercial development projects to gain an insight into the problems faced by the new developers in adopting these agile practices. The aim of the study was to investigate the effects of the XP practices on the qu...

It is shown that three-dimensional charged black holes can approach the extreme state at nonzero temperature. Unlike even dimensional cases, the entropy for the extreme three-dimensional charged black hole is uniquely described by the BekensteinHawking formula, regardless of different treatments of preparing the extreme black hole, namely, Hawking’s treatment and Zaslavskii’s treatment. PACS nu...

This paper presents a single case study reporting the experiences of introducing extreme programming (XP) in a small development project at Online Telemarketing in Lund, Sweden. The project was a success despite the fact that the customer had a poor idea of the system required at the start of the development. This success is partly due to the introduction of practically all of the XP practices....

In order to estimate the minimum volume set of a probability very close to zero, a plug-in estimator of density level set is built based on the adaptive splitting technique, a rare event dedicated probability technique. This algorithm is the main novelty of this paper. It is applied on the realistic estimation of a booster fallout zone.
