This paper presents the results of experimental research and mathematical modelling in terms influence periodic dynamic instabilities have on condensation phase change R1234yf R1234ze refrigerants tubular minichannels. The main reason for this was fact that under Montreal Protocol (1986), as well Regulation No 517/2014 European Parliament Council 16 April 2014, F-gases such hydrofluorocarbons (...
The motivation behind the concept of Knowledge Federation resonates closely with the orientation of the Hypermedia Discourse project and the Knowledge Cartography focus of a forthcoming book. We are concerned with the co-evolution of new tools and practices for “bringing together” ideas, sharing the KF orientation that meaning is always contextualised, that truth is often contested, and that so...
although homotopy-based methods, namely homotopy analysis method andhomotopy perturbation method, have largely been used to solve functionalequations, there are still serious questions on the convergence issue of thesemethods. some authors have tried to prove convergence of these methods, butthe researchers in this article indicate that some of those discussions are faulty.here, after criticizi...

Tryptophol [2-(3-indolyl)-ethanol], a well-known constituent of terrestrial plants and microorganisms, has so far been isolated from tryptophan fermentations, plant seedlings, Aspergillus niger, Agrobacterium tumefaciens, Ceratocystis spp., and Rhizobium spp. (Buckingham, 1994). We have now isolated tryptophol from the marine sponge Ircinia spinulosa collected from the Aegean Sea. In addition t...
in this paper, we prove a common fixed point theorem for six mappings (two set valued and four single valued mappings) without assuming compatibility and continuity of any mapping on non complete metric spaces. to prove the theorem, we use a non compatible condition, that is, weak commutativity of type (kb). we show that completeness of the whole space is not necessary for the existence and uni...
The JISC-funded Memetic 2 project was designed as knowledge management and project memory support for teams meeting via the Access Grid environment (Buckingham Shum et al, 2006). This paper describes how these capabilities also enable it to serve as a novel distributed video analysis tool to support interaction analysis. Memetic technologies can be used to record, annotate and discuss sessions ...
This article presents an overview of the development and use of analytics in the context of education. Using Buckingham Shum's three levels of analytics, the authors present a critical analysis of current developments in the domain of learning analytics, and contrast the potential value of analytics research and development with real world educational implementation and practice. The article al...
