The software industry increasingly turns to Model-Driven Engineering (MDE) to mitigate complexity by automating model creation and transformation. Many organisations are pursuing Integrated Development Platforms (IDPs) to enhance automation in ...

Existing programming models tend to tightly interleave algorithm and optimization in HPC simulation codes. This requires scientists to become experts in both the simulated domain and the optimization process and makes the code difficult to maintain ...$\mathrm{}\mathrm{}\mathrm{}$${\mathrm{}\mathrm{}\mathrm{}}_{\mathsf{}}$${\mathrm{}\mathrm{}\mathrm{}}_{\mathsf{}}$${\mathrm{}\mathrm{}\mathrm{}}_{\mathsf{}}$${\mathrm{}\mathrm{}\mathrm{}}_{\mathsf{}}$${\mathrm{}\mathrm{}\mathrm{}}_{\mathsf{}\mathsf{}}$${\mathrm{}\mathrm{}\mathrm{}}_{\mathsf{}\mathsf{}}$${\mathrm{}\mathrm{}\mathrm{}}_{\mathsf{}\mathsf{}}$${\mathrm{}\mathrm{}\mathrm{}}_{\mathsf{}}$

This paper describes LFRic: the new weather and climate modelling system being developed by the UK Met Office to replace the existing Unified Model in preparation for exascale computing in the 2020s. LFRic uses the GungHo dynamical ...

• A new dynamical core and software infrastructure for weather and climate modelling.

The growing use of models for separating concerns in complex systems has lead to a proliferation of model composition operators. These composition operators have traditionally been defined from scratch following various approaches differing in formality,...

Developers spend a substantial amount of their time with program comprehension. To improve their comprehension and refresh their memory, developers need to communicate with other developers, read the documentation, and analyze the source code. Many ...

We describe the synergies gained by enabling variants for product lines, or features, to be modeled in the same master syntax as design models (class diagrams, state diagrams, composite structure) and traditional source code. Our approach, using a ...

Business Process Management is a powerful approach for the automation of collaborative business processes. Recently concepts have been introduced to allow batch processing in business processes addressing the needs of different industries. The ...

Human use of land increasingly alters the structure and the functioning of the environment. To ex-ante understand and anticipate these changes there is an increased need for readily available and operational land use change models. One ...

• iCLUE is a new member of the commonly used CLUE land use change model family.
• ...

Existing programming models tend to tightly interleave algorithm and optimization in HPC simulation codes. This requires scientists to become experts in both the simulated domain and the optimization process and makes the code difficult to ...

Since its inception in 1996, aspect-oriented programming (AOP) has been believed to reduce the effort required to maintain software systems by replacing cross-cutting code with aspects. However, little convincing empirical evidence exists to support ...

Until recently decisions were mostly modelled within the process. Such an approach was shown to impair the maintainability, scalability, and flexibility of both processes and decisions. Lately, literature is moving towards a separation of concerns ...

In data-centric crowdsourcing, the output data are sensitive to the incentive structure connected to the workers' behavior. This paper proposes to use a declarative language to explicitly handle both data computation and the incentive structure. The ...

Developers base selection of a User Interface (UI) development approach on functionality, development and maintenance costs, usability, responsiveness, etc. User expectations continue to grow for greater functionality and continuous interactivity, ...

When considering distributed enterprise applications interacting with data, one can rarely omit its security concerns that must enforce data integrity and prevent users from disallowed actions. Current trends of application design tend to deal with ...

Modeling and simulation have been heavily used in epidemiology, for instance to study the transmission of infectious diseases, their pathogenicity and their propagation. A major hindrance to modeling in epidemiology is the mixing of concerns that ought ...

The complexity of user interface (UI) design grows quickly with the number of application concerns. Such complexity compounds with additional requirement of contextual-awareness (i.e., adapt to user location, skill level, etc.) and support of ...

The development of efficient data flow analyses is a complicated task. As requirements change and special cases have to be considered, implementations may get hard to maintain, test and reuse. We propose to design these analyses regarding the principle ...

A large proportion of the requirements on embedded real-time systems stems from the extra-functional dimensions of time and space determinism, dependability, safety and security, and it is addressed at the software level. The adoption of a sound ...

The focus of this paper is on identification of typical graphical user interface (GUI) programming concerns. As opposed to some other proposals available in the literature that indicate GUI programming concerns by simple intuition, we have conducted a ...

The flexibility offered by dynamically typed programming languages has been appropriately used to develop specific scenarios where dynamic adaptability is an important issue. This has made some existing statically typed languages gradually incorporate ...
