This paper is an extended version of the Credo Methodology [16]. Credo offers tools and techniques to model and analyze highly reconfigurable distributed systems. In a previous version we presented an integrated methodology to use the Credo tool suite. Following a compositional, component-based approach to model and analyze distributed systems, we presented a separation of the system into components and the network. A high-level, abstract representation of the dataflow level on the network was given in terms of behavioral interface automata and a detailed model of the components in terms of Creol models. Here we extend the methodology with a detailed model of the network connecting these components. The Vereofy tool set is used to model and analyze the dataflow of the network in detail. The behavioral automata connect the detailed model of the network and the detailed model of the components. We apply the extended methodology to our running example, a peer-to-peer file-sharing system.

In this paper we discuss and elaborate on the conceptual requirements as well as the tools of the General AMIGO Model for group communication. The special features of the model are examined with particular reference to the social and ethical implications in the communication process. The applicability of the AMIGO Model is demonstrated by examples, and we give indications of further work to refine and advance the model.

In this paper we use HI-Maude to model and analyze the human thermoregulatory system and the effect of extreme heat exposure on the human body. This work is motivated by the 2010 Sauna World Championships, which ended in a tragedy when the last two finalists were severely burnt in surprisingly short time (one of them died the next day). HI-Maude is a recent rewriting-logic-based formal modeling language and analysis tool for complex hybrid systems whose components influence each others' continuous dynamics. One distinguishing feature of HI-Maude is that the user only needs to describe the continuous dynamics of single components and interactions, instead of having to explicitly define the continuous dynamics of the entire system. HI-Maude analyses are based on numerical approximations of the system's continuous behaviors. Our detailed models of human thermoregulation and the sauna used in the world championships allow us to use HI-Maude to formally analyze how long the human body can survive when experiencing extreme conditions, as well as analyzing possible explanations for the still unsolved tragedy at the 2010 Sauna World Championships.

The HATS project aims at developing a model-centric methodology for the design, implementation and verification of highly configurable systems, such as software product lines, centred around the Abstract Behavioural Specification (ABS) modelling Language. This article describes the variability modelling features of the ABS Modelling framework. It consists of four languages, namely, μTVL for describing feature models at a high level of abstraction, the Delta Modelling Language DML for describing variability of the ??code' base in terms of delta modules, the Product Line Configuration Language CL for linking feature models and delta modules together and the Product Selection Language PSL for describing a specific product to extract from a product line. Both formal semantics and examples of each language are presented.

We present a description and analysis of the data access challenge in the Siemens Energy. We advocate for Ontology Based Data Access (OBDA) as a suitable Semantic Web driven technology to address the challenge. We derive requirements for applying OBDA in Siemens, review existing OBDA systems and discuss their limitations with respect to the Siemens requirements. We then introduce the Optique platform as a suitable OBDA solution for Siemens. Finally, we describe our preliminary installation and evaluation of the platform in Siemens.

This paper presents a timed CTL model checker for Real-Time Maude and its semantic foundations. In particular, we give a timed CTL model checking procedure for that is sound and complete for closed-bound formulas under a continuous semantics for a fairly large class of systems. An important benefit of our model checker is that it also automatically provides a timed CTL model checker for subsets of modeling languages, like Ptolemy II and (Synchronous) AADL, which have Real-Time Maude model checking integrated into their tool environments.
