In the context of the Markovian dynamical evolution in a nonstationary thermal bath, we construct a family of fluctuation relations for the entropy production that are not verified by the work performed on the system. We exhibit fluctuation relations, which are global versions either of the generalized fluctuation-dissipation theorem around a nonequilibrium diffusion or of the usual fluctuation...

Observing the evolution of a pathology in medical images, or of soil occupation in remote sensing, detecting changes in video sequences, updating a spatial information system are examples that can all benefit from quantification and comparison of spatial relations between objects in the observed scenes. In this paper, we propose two approaches to compare spatial relations represented as fuzzy s...

This research presents a brief review of the different definitions of Web 2.0 and presents the most important Web 2.0 Technologies that underlie the evolution of the Web. We map these Web 2.0 technologies to the Social Computing Principles and describe the different relations and patterns that occur. We argue that creating insight into the relations between Web 2.0 Technologies and Principles w...

Database evolution can be considered a combination of schema evolution, in which the structure evolves with the addition and deletion of attributes and relations, together with domain evolution in which an attribute’s specification, semantics and/or range of allowable values changes. We present a model in which mesodata – an additional domain definition layer containing domain structure and int...

Most software systems evolve, with time, in response to changing functional and non-function requirements. This evolution aaects both the dynamic behavior of the system as well as the form of the static software ar-tifacts (e.g., source code, user documentation, requirements speciications, design diagrams, test scripts) that comprise the system. A major challenge facing software practitioners i...

Using Spitzer archival data from the SAGE (Surveying the Agents of a Galaxy’s Evolution) program, we derive the Cepheid period-luminosity (P-L) relation at 3.6, 4.5, 5.8 and 8.0 microns for Large Magellanic Cloud (LMC) Cepheids. These P-L relations can be used, for example, in future extragalactic distance scale studies carried out with the James Webb Space Telescope. We also derive Cepheid per...

Abstract One of the pressing issues in philosophy technology is role human creativity human-technology relations. We first observe that a techno-centric orientation leaves open and contribution technological evolution, while an anthropocentric technical milieu evolution. Subsequently, we develop concept creation as deviation responsiveness response to affordances environment, inspired by afford...

Metamorphic testing enables the generation of test cases in the absence of an oracle by exploiting relations among different executions of the program under test, called metamorphic relations. In a recent survey, we observed a great variability in the way metamorphic relations are described, typically in an informal manner using natural language. We noticed that the lack of a standard mechanism...

Nested relations are an important subclass of object-relational systems that are now being widely used in industry. Also, a subclass of nested relations, partitioned normal form (PNF) relations, is important because the semantics and manipulation of these relations are more transparent than general nested relations. In this paper we address the question of determining when every PNF relation st...
