Dependable LQNS is a software tool for modeling and evaluating performability of fault-tolerant layered distributed applications that use a separate architecture for failure detection and reconfiguration. It takes into account the effects of management architecture, application software architecture, failure of management and application components in the dependability computation. It uses a co...

A novel layered graphene-based architecture is achieved via an ordered self-assembly process. Amphipathic graphene nanosheets are joined horizontally into large sheets via edge splicing, and a cross-linking agent of poly(vinyl alcohol) bridges them into integrated three-dimensional monoliths with tunable interlayer spacing. This layered architecture possesses highly ordered and favorable microc...

In this paper we present an approach to implementing behaviour-based control using a three-layered architecture. In this way we intend to combine the advantages of both approaches: exibility of behaviour-based control speciication with formal analysis and software generation tools developped for the layered architecture.

Separation of concerns is a determining factor of the quality of object-oriented software development. Done well, it can provide substantial benefits such as additive rather than invasive change and improved adaptability, customizability, and reuse. In this paper we propose a software architecture that integrates concepts from business process modeling with concepts of object-oriented systems d...

I this essay, we argue that pervasive digitization gives birth to a new type of product architecture: the layered modular architecture. The layered modular architecture extends the modular architecture of physical products by incorporating four loosely coupled layers of devices, networks, services, and contents created by digital technology. We posit that this new architecture instigates profou...

E-readiness is one of the major prerequisites for effective implementation of e-government. For the correct implementation of e-government, it is needed to accurately assess the state of e-readiness in desired community. In this regard, there are models to assess, but the correct choice of model is one of the most important challenges in this area. The process of evaluating and selecting the ap...

Wireless networks initially inherited the traditional layered architecture from wired networks. Nevertheless, as third and fourth generation wireless communications and networking begin to proliferate in the area of communication networks, the suitability of the layered architecture is coming under close scrutiny from the research community. It is repeatedly argued that although layered archite...

Architectural styles and patterns play an important role in software engineering. One of the most known ones is the layered architecture style. However, this style is usually only stated informally, which may cause problems such as ambiguity, wrong conclusions, and difficulty when checking the conformance of a system to the style. We address these problems by providing a formal, denotational se...
