We discuss the application of diffraction theory to the reshaping of freely propagating terahertz pulses by narrow apertures. This is accomplished by using two separate electrooptic sampling detectors. The first contains a narrow electrode geometry that does not modify the frequency content of the incident terahertz field, while the second contains a narrow gap between two large electrodes. The...

We experimentally demonstrate the direct measurement of net group and reshaping delays for arbitrary optical pulses in dispersive media, verifying the earlier prediction of Peatross et al. [Phys. Rev. Lett. 84, 2370 (2000)]. Incoherent pulse propagation in an absorptionless system is well described by net group delay; even the medium causes a great deal of deformation in the transmitted pulse. ...

More and more often, we face the necessity of extracting appropriately reshaped knowledge from an integrated representation of the information space. Be such a global representation a central database, a global view of several ones or an ontological representation of an information domain, we face the need to define personalised views for the knowledge stakeholders: single users, companies or a...

OBJECTIVES This study describes the process of tissue electroforming and how shape changes in cartilage can be produced by the application of direct current (DC). The dependence of shape change on voltage and application time is explored. STUDY DESIGN Basic investigation using ex vivo porcine septal cartilage grafts and electromechanical cartilage deformation focused on development of a new s...

Two technologies are currently reshaping Accounting Information Systems: In-Memory Technology and Mobile Technology. It is not only a matter of generic increase of performances, as it usually occurs in the IT field, but a dramatic improvement that is affecting hardware and software architecture and even the organization of the actual systems. We are facing a new generation of BI tools that will...

Anchored Large Woody Debris (LWD) is increasingly being used as one of several nature-based coastal protection strategies along the north-western coasts Canada and US. As an alternative to conventional hard armoring (e.g., seawalls), its usage widely considered be less harmful ecosystem while maintaining ability protect beaches against wave attack erosion. The effects seawalls on have been exte...
