The aim of this study is to investigate the effect of boundary conditions on the accuracy and stability of the numerical solution of fluid flows in the context of single relaxation time Lattice Boltzmann method (SRT-LBM). The fluid flows are simulated using regularized, no-slip, Zou-He and bounce back boundary conditions for straight surfaces in a lid driven cavity and the two-dimensional flow ...

wetlands as water resources have a special place in the semi-arid plateau of iran and boundary determination is necessary for their effective conservation and conflict resolution among stakeholders that are dependent on these resources. determination of the wetland boundaries should be commensurate with environmental features affecting on it which normally extend beyond water extent. ecological...

The paper analyses the development of organised markets for the trading of stock options and focuses on the role that risk management techniques played in the evolution of these markets. The paper’s main claim is that financial risk management turned into a boundary object in options markets – a set of instructions and practices that served as a common ground and as a basis for discussion and o...

A variety of privacy mechanisms have been designed for the online environment but they have not been effective in ensuring end-users’ privacy. In this study, we analyse existing privacy theories devised from offline sociopsychological studies and discuss which of those could be useful in the design of usable online privacy. We found that the Communication Privacy Management framework which prov...

It is not a trivial job to maintain clusters in a highly mobile ad hoc scenario where changes in node activity status cause frequent and unpredictable topological changes. It requires continuous and efficient management protocol for frequent up-dation and re-clustering which are costly in a resource-poor environment. In this context, we describe a convenient cluster management protocol that inc...

Scrum has gained surprising momentum as an agile IS project management approach. An obvious question is why Scrum is so useful? To answer that question we carried out a longitudinal study of a distributed project using Scrum. We analyzed the data using coding and categorisation and three carefully selected theoretical frameworks. Our conclusion in this paper is that Scrum is so useful because i...

Previous research on the determinants of effectiveness in knowledge systems seeking to support sustainable development has highlighted the importance of "boundary work" through which research communities organize their relations with new science, other sources of knowledge, and the worlds of action and policymaking. A growing body of scholarship postulates specific attributes of boundary work t...
