It is well known fact that computing introduces a set of solutions to many challenges that are faced by the current society. The computing applications proposed now are capable of operating in highly dynamic environments and placing minimal demands on users' work. Many newer applications now aim to meet these requirements by adapting to selected aspects of the context of use, such as the current location, time and user activities. In recent years, a variety of prototypical computing applications have appeared, ranging from small to large as well as complex ones.
The Journal, Progress in Computing Applications (PCA) is journal thus concentrate on applications rather than the presentation of theoretical aspects such as concepts, architectures and algorithms. The journal will publish all aspects of computing papers other than the theory and other related papers. In the wider sense, we are interested in investigating several aspects of the computing engineering process that remain poorly understood in relation to other domains. We believe that challenges related to testing, in particular, will need to be addressed further before the applications become live.
