The community experiences both positive and negative consequences as a response of Qibla direction calibration, particularly in the ancient mosque, an ancestral heritage mosque whose authenticity must be preserved. One them is Air Tiris Great Mosque Kampar, which preserved from initial stages growth because it tourist destination item cultural heritage. This article aims to verify calibration o...

The subject matter of this paper concerns the numerical approximation of reduced Vlasov-Maxwell models by semi-Lagrangian schemes. Such reduced systems have been introduced recently in the literature for studying the laser-plasma interaction. We recall the main existence and uniqueness results on these topics, we present the semi-Lagrangian scheme and finally we establish the convergence of thi...

If L is the combinatorial Laplacian of a graph, exp(−L t) converges to a matrix with identical coefficients. The speed of convergence is measured by the maximal entropy distance. When the graph is the sum of a large number of components, a cut-off phenomenon may occur: before some instant the distance to equilibrium tends to infinity; after that instant it tends to 0. A sufficient condition for...

This document is intended to stimulate debate and discussion in preparation of the Escience Scoping Study Expert Seminar for archaeology and the historic environment. It is a tentative, partial and therefore controversial delineation of the challenges and opportunities which the E-science agenda presents archaeologists and the historic environment sector. It proposes areas of specific activity ...

This paper proposes a model for multilateral contracting, where contracts are written and renegotiated over time, and where contracts may impose externalities on other agents. Equilibria always exist and the equilibrium value function is linear and monotonically increasing on the contracts. If the grand coalition, or contracting among all agents, is inefficient we show that bargaining delays ar...
