In the Order-Maintenance Problem, the objective is to maintain a total order subject to insertions, deletions, and precedence queries. Known optimal solutions, due to Dietz and Sleator, are complicated. We present new algorithms that match the bounds of Dietz and Sleator. Our solutions are simple, and we present experimental evidence that suggests that they are superior in practice.

Reflective journals have been used widely in teacher education programs to promote reflective thinking (Freidus, 1998; Carter & Francis, 2000; Yost, Senter & ForlenzoBailey, 2000). Smyth (1992) advocated that posing a series of questions to be answered in written journals could enhance reflective thinking. It was for this reason that reflective responses to directed questions were introduced in...

Surface physico-chemical and thermodynamic properties of non ionic surfactants (Tween 20 and Tween 80) with diblock copolymer poly (oxyethylene/oxybutylene) (E39B19) at 298 K have been investigated by surface tension and conductivity techniques. The surface tensiometery were used to study the critical micelle concentration (CMC), surface excess concentration (Г), minimum area per molecule (A), ...

A simple and efficient method for quantum Monte Carlo simulation is presented, based on discretization of the action in the path integral, and a Gaussian averaging of the potential, which works well e.g. with the Coulomb potential. Non-integrable hard core potentials can not be averaged in the same way.

In India, a dramatic increase in the burden of ischemic heart disease (IHD) has been accompanied by expanded use coronary catheterization and percutaneous intervention (PCI). This growth occurred during period dynamic change within Indian healthcare system, characterized substantial investments infrastructure, introduction national health insurance – Prime Minister’s Jan Arogya Yojana (PM-JAY) ...

We discuss the problem of interpolating C Hermite data on the sphere (two points with associated first derivative vectors) by spherical rational curves. With the help of the generalized stereographic projection (Dietz et al., 1993), we construct a two– parameter family of spherical quartics solving this problem. We study the shape of these solutions and derive criteria which guarantee solutions...
