This paper presents a value-based software process framework that has been derived from the 4+1 theory of value-based software engineering (VBSE). The value-based process framework integrates the four component theories – dependency, utility, decision, and control, to the central theory W, and orients itself as a 7-step process guide to practice value-based software engineering. We also illustr...

A digraph G is called primitive if for some positive integer k, there is a walk of length exactly k from each vertex u to each vertex v (possibly u again). If G is primitive, the smallest such k is called the exponent of G, denoted by exp(G). A digraph G is said to be r-regular if each vertex in G has outdegree and indegree exactly r. It is proved that if G is a primitive 2-regular digraph with...

We consider oriented bond percolation on Zd × N, at the critical occupation density pc, for d > 4. The model is a “spread-out” model having long range parameterised by L. We consider configurations in which the cluster of the origin survives to time n, and scale space by n1/2. We prove that for L sufficiently large all the moment measures converge, as n →∞, to those of the canonical measure of ...

In this paper we construct an information-theoretic model of architectural drawings. This model is then used to quantify and measure the complexities and similarities of drawings. The approach is applied within a linear qualitative shape representation but can be generalized to other types of representation. The descriptive and analytic power of the proposed methods are demonstrated by studying...

When thinking about traditional Iranian architecture, one imagines extensive ornamental patterns that adorn almost every surface of mosques and other prominent buildings. Yet, many theories of architecture since the beginning of twentieth century have considered ornamentation a superficial and superfluous layer. But, are these ornamental surfaces superficial and can they be removed so easily? T...

The mutual experience of European architecture during the transmission phase of Romanesque (around 11th and 12th centuries) to Gothic style simultaneous with Mongol invasions and political revolution from Seljuk empire to Ilkhanids have been assumed as a turning point through Iranian and European architecture. Thus, clarifying its mutual properties is one of the controversial discussion topics ...
