Plate impact experiments are a powerful tool in equation of state development, but are inherently limited by the range of impact velocities accessible to the facility. In an effort to dramatically increase the range of pressures which can be studied with available impact velocities, a new experimental technique is examined. The target plate is replaced by a composite assembly consisting of two ...

Target preheat is a significant concern in inertial confinement fusion experiments because, when the temperature of the target becomes too large, the areal density (density times radius) required for ignition cannot be attained. The majority of preheat comes from fast electrons produced when the laser interacts with the target. When these energetic electrons are slowed by collisions, they relea...

This paper proposes a scheme to produce realistic force reflection in a needle insertion problem. The target system is the spine needle biopsy simulator for tumor inspection by needle insertion. Simulated force is calculated using the 3D human tissue model, the orientation and position of the needle, and this force is produced through the PHANToM device. To generate realistic force reflection, ...

The paper discuses the effect of initial stresses on the reflection coefficients of plane waves in a dissipative medium. Basic governing equations are formulated in context of Biot's incremental deformation theory. These governing equations are solved analytically to obtain the dimensional phase velocities of plane waves propagating in plane of symmetry. Closed-form expressions for the reflecti...

There are two basic categories of reflection, according to where the learner reflects on. In self-reflection, the learner reflects on her/his own actions, while in comparative reflection the learner reflects on others’ actions. We propose an alternative reflection type, as a subcategory of the comparative reflection, the analogical reflection. In analogical reflection, students reflect on analo...

This qualitative case study explores perceptions of university tutors and student teachers involved in a Postgraduate Certificate in Education (PGCE) programme, at a UK university, regarding the connotation and implementation of reflection as a teacher education concept. Reflection has been a complex and at times elusive educational concept; however, in many educational programmes it is often a...

In this paper, the strong solutions (X,L) of multidimensional stochastic differential equations with reflecting boundary and possible anticipating initial random variables is established. The key is to obtain some substitution formula for Stratonovich integrals via a uniform convergence of the corresponding Riemann sums and to prove continuity of functionals of (X,L).
