Graphical languages such as dataflow diagrams, entity-relationship diagrams or organization charts are used to describe various aspects of organizations. These languages have their origins in the field of software-engineering and organizational theory. Looking at organizations regarding Grochlas sociotechnical systems [Grochla, 1978, p. 10] these languages describe the rules, which have to be f...

Explanations in the life sciences frequently involve presenting a model of the mechanism taken to be responsible for a given phenomenon. Such explanations depart in numerous ways from nomological explanations commonly presented in philosophy of science. This paper focuses on three sorts of differences. First, scientists who develop mechanistic explanations are not limited to linguistic represen...

Abstract The way from the path integral to Feynman diagrams is sketched. emphasis put on decrease of complexity in this process, infinite-dimensional integrals down apparent simplicity child’s play. On other hand, also subsequent increase when using make realistic physical predictions described, thus illustrating dialectic between and clarity diagrams, their practical applications.

We study alternating strand diagrams on the disk with an orbifold point. These are quotients by rotation of Postnikov disk, and we call them diagrams. associate a quiver potential to each diagram, in such way that its Jacobian algebra one associated covering diagram related skew-group construction. moreover realise this as endomorphism certain explicit cluster-tilting object. This is similar (a...

In software development a system is often viewed by various models at different levels of abstraction. It is very difficult to maintain the consistency between them for both structural and behavioral semantics. This paper focuses on a formal foundation for presenting scenarios and reasoning the synchronization between them. We represent such a synchronization using a transition system, where a ...

The electric dipole moment of the muon (dμ) is evaluated in a two Higgs doublet model with a softly broken discrete symmetry. For tan β ≡ |v2|/|v1| ∼ 1, contributions from two loop diagrams involving the t quark and the W boson dominate; while for tan β ∼ > 10, contributions from two loop diagrams involving the b quark and the τ lepton are dominant. For 8 ∼ > tan β ∼ > 4, significant cancellati...

Cognitive disabilities are the least understood and the least discussed type of disability among web developers [1]. Some work has explained how developers should create web contents that could be accessible to people with cognitive disabilities [1-4]. While these guidelines are definitely a valuable first step toward making the web more accessible to people with disabilities, the task of creat...
