Solving the Sequential Travel Forecasting Procedure with Feedback 16th PTV Vision User Group Meeting 2006 David Boyce, Northwestern University Hillel Bar-Gera, Ben-Gurion University of the Negev Since the outset of urban transportation planning in the USA during the 1950s, travel forecasting has been characterized by the solution of a sequence of models: trip generation, trip distribution, mode...

Many effective automatic surface simplification algorithms have been developed. These automatic algorithms create very plausible results in many cases, but at very low levels of detail they do not preserve the visual appearance of the original model very well. This could be improved if surface simplification algorithms were able to make use of semantic or high-level meaning of models. The idea ...

background esophageal, stomach, and colorectal cancers are commonly lethal gastrointestinal tract (git) neoplasms, causing almost two million deaths worldwide each year. some environmental risk factors are acknowledged; however, genetic defects can significantly contribute to predisposition to git cancers. accordingly, recent works have shown that single-nucleotide polymorphisms (snps) within m...

One of the most debilitating disorders is adductor spasmodic dysphonia (ADSD), a voice disorder caused by involuntary movements of the muscles of the larynx (voice box). For treating ADSD, botulinum toxin (BT) injections turned out to be very useful. However, the effects of BT are highly variable, so at present, there is no objective criterion of when such a BT treatment is necessary. It is the...

Internet Small Computer Systems Interface (iSCSI) is a Small Computer Systems Interface (SCSI) transport protocol designed to run on top of TCP. The iSCSI session abstraction is equivalent to the classic SCSI "I_T nexus", which represents the logical relationship between an Initiator and a Target (I and T) required in order to communicate via the SCSI family of protocols. The iSCSI session prov...

AIMS To review the Batra Hospital and Medical Research Centre experience of using compensator-based intensity-modulated radiotherapy (IMRT) to treat head and neck cancer. MATERIALS AND METHODS Between October 2003 and August 2004, 18 patients underwent IMRT for head and neck cancer at our institution. IMRT was delivered using partial transmission high-resolution compensator blocks. RESULTS ...

background: in radiation treatment of moving targets located in thorax region of patient body, the delivered dose does not match with the planned treatment, resulting in some over and under dosage in the tumor volume, as a function of motion magnitude and frequency. several efforts have been done to investigate the target motion effects on dose distribution in the target and surrounding normal ...
