It is common in shallow seismic studies for the compressional-wave velocity in unconsolidated sediments to increase by a factor of four or more at the transition from dry or partial water saturation to full saturation. Under these conditions, conventional NMO velocity analysis fails and leads to large depth and layer thickness estimates if the Dix equation is assumed valid. Prestack depth migra...

Frameworks such as activity theory, distributed cognition and structuration theory, amongst others, have shown that detailed study of contextual settings where users work (or live) could help the design of interactive systems. However, these frameworks do not adequately focus on accounting for the materiality (and embodiment) of the contextual settings. Within the IST-EU funded AMIDA project (A...

Executive Summary There are many sources of data integrity errors within storage networks and devices. The T10 (SCSI) standards committee developed the Data Integrity Field specification (DIF) to provide protection within storage disks by extending the size of disk sectors by 8 bytes, which contain protection information, including a 16 bit CRC. This integrity metadata enables corrupted write a...

UNLABELLED Benign Paroxysmal Positional Vertigo (BPPV) is one of the most frequent diseases of the vestibular system and it is characterized by episodes of recurrent vertigo triggered by head movements or position changes. There are several approaches for treatment, but efficacy is still being discussed. AIM To asses the effectiveness of the specific maneuvers available to the treatment of BP...
