Modem computer systems possess two main characteristics: their ever- growing complexity and the increasing number and range of abnormal situa- tions they have to cope with successfully in order to deliver the service. Developing such systems is ademanding task requiring discipline and cIear thinking, which are best ensured by the right design mechanisms aiming at both appropriate system structuring and a disciplined provision of fault toler- ance. The groundlaying research of the 60s and 70s created a solid basis in this area by developing a number of fundamental mechanisms, such as ACID (atomicity, consistency, isolation and durability) transactions, atomic actions (Brain Randell's conversations) and exception handling. Later on, a number of advanced techniques were proposed to overcome some of the limitations and rigidity of these mechanisms and to allow system developers to effec- tively deal with specific characteristics of a particular application, an applica- tion domain, design paradigm and execution environment. These incIude a variety of advanced transactional schemes and a number of novel exception handling techniques.In the last years, there has been a surge of interest in developing more advanced mechanisms combining properties of several fundamental mecha- nisms to make it easier for system developers to cope, in a more flexible and efficient fashion, with complexity, distribution and heterogeneity of emerging applications as weil as with an increasing variety of possible faults.

This book presents a comprehensive documentation of the scientific outcome of satellite events held at the 14th International Conference on Model-Driven Engineering, Languages and Systems, MODELS 2011, held in Wellington, New Zealand, in October 2011. In addition to 3 contributions each of the doctoral symposium and the educators' symposium, papers from the following workshops are included: variability for you; multi-paradigm modeling; experiences and empirical studies in software modelling; models@run.time; model-driven engineering, verification and validation; comparing modeling approaches; models and evoluation; and model-based architecting and construction of embedded systems.

The LNCS journal Transactions on Aspect-Oriented Software Development is devoted to all facets of aspect-oriented software development (AOSD) techniques in the context of all phases of the software life cycle, from requirements and design to implementation, maintenance and evolution. The focus of the journal is on approaches for systematic identification, modularization, representation and composition of crosscutting concerns, i.e., the aspects and evaluation of such approaches and their impact on improving quality attributes of software systems. This volume, the 11th in the Transactions on Aspect-Oriented Software Development series, consists of two parts. The first part focuses on runtime verification and analysis, highlighting runtime verification as a "killer" application of aspect-orientation. The second part contains revised and extended versions of the five best papers submitted to Modularity:aosd 2013, presenting current research related to modularity and covering topics such as formal methods and type systems, static analysis approaches for software architectures, model-driven engineering and model composition, aspect-oriented programming, event-driven programming and reactive programming.
