When first formulated in the early seventies, the laws of software evolution were, for a number of reasons, not widely accepted as relevant to software engineering practice. Over the years, they have gradually become recognised as providing useful inputs to understanding of the software process and have found their place in a number of software engineering curricula. Now eight in number, they h...

Aim: To determine the characteristics of emergency department (ED) presentations during Ramadan Feast and Sacrifice.Materials Methods: We compared patients that presented to ED public holiday for Sacrifice in 2018 2019.Results: During study periods, 37737 people ED. Compared non-holiday time, presenting increased by 14.4%, those 9.8% (p<0.001 both). While there was an increase hospitaliz...

This paper argues that quantitative process models must be considered essential to support sustained improvement of E-type software evolution processes and summarises some of the experiences gained in the FEAST projects to date. Modelling guidelines are provided.

In the article, using authentic Lithuanian material, celebration of St Martin’s Day in Lithuania Minor is analysed from a chronological point view (from first mention to present day), order show general stages development festival, and modern changes customs. The paper analyses feast late 19th 20th century, showing structural functional calendar feast. It also aims analyse customs festival (sin...

This paper describes one of the latest in a series of system dynamics models developed during the FEAST (Feedback, Evolution And Software Technology) investigation into software evolution processes. The intention of early models was to simulate real-world processes in order to increase understanding of such processes. The work resulted in a number of lessons learnt, in particular, with regard t...
