Centric concerns

Dealing with concerns ask for an architecture-centric approach

It is becoming more and more clear that architectural design is a crucial step in building complex software. Architectural design involves the first and most crucial design decisions to meet the expected quality attributes [1]. Dealing with concerns that influence important quality attributes asks for an architecture-centric approach. In this paper we propose architectural concerns as basic con...

Centric connectivity index by shell matrices

Relative centricity RC values of vertices/atoms are calculated within the Distance Detour and Cluj-Distance criteria on their corresponding Shell transforms. The vertex RC distribution in a molecular graph gives atom equivalence classes, useful in interpretation of NMR spectra. Timed by vertex valences, RC provides a new index, called Centric Connectivity CC, which can be useful in the topologi...

The Six Concerns for Separation of Concerns

Despite a common agreement on the necessity of the application of the separation of concerns (SOC) principle, there is not yet a consensus for its key issues. The separation of the concerns is usually based on the adopted programming paradigm, the applied method or even the programming language. This paper presents the so-called six ‘C’ properties that can be applied as a guideline for defining...

From Process-Centric to Data Centric Replication

Mountain concerns

While global fears mount about the dwindling numbers of many amphibian species as a result of disease and other unknown factors, three separate teams of researchers have announced the discovery of several new species and other organisms in the mountain rainforests of Colombia, Tanzania and India. Scientists in Bogata carried out a ‘rapid assessment program’ expedition over three weeks in the mo...
