Dynamic evolution and adaptation of workflow models due to process (re)engineering activities and dynamic changing situations of the real process is one of the most important challenges in workflow management. In this paper, we present an approach for the management of evolving workflow specifications which copes with the evolution of a workflow schema and the dynamic modification of workflow i...

The isolation of a computing environment is an integral part of a digital forensic process. Isolation helps prevent evidence contamination and possible tampering. This paper focuses on the process of isolating instances in cloud computing systems. Several conditions are specified to serve as a guide for the successful isolation of cloud instances. Also, the complications that can arise during a...

1. Current situation and state of the art. As surveys [RRD04a, SMR08] and books [RW12] show, flexibility and evolution in PAIS cover several dimensions ranging from design time flexibility (by underspecification or based on declarative models), runtime flexibility where we can distinguish between “foreseen” exceptions (to be dealt with by compensation or rollback) and “unforeseen” exceptions (d...

Generalisations of geometry have emerged in various forms the study field theory and quantization. This mini-review focuses on role higher three selected physical applications. After motivating describing some basic aspects algebroid structures bundles (differential graded) Q-manifolds, we briefly discuss their relation to $$(\alpha )$$ Batalin–Vilkovisky quantization topological sigma models, ...

Most valid rules that are learned from very large and high dimensional data sets are not interesting, but are already known to the users. The dominant model of the overall data set may well suppress the interesting local patterns. The search for interesting local patterns can be implemented by a two step learning approach which rst acquires the global models before it focuses on the rest in ord...

The first Waste Framework Directive issued by the European Union dates back to seventies but was drastically amended in last decade reduce environmental impacts of waste encouraging reuse, recycling and remanufacturing. Product recovery starts with disassembly which results high labor costs. Disassembly supports environmentally conscious choices like replacement defective parts extend life span...
