introduction: in this study, a computer analysis method based on a block matching algorithm is presented to extract the longitudinal movement of the carotid artery wall using consecutive ultrasonic images. a window (block) is selected as the reference block in the first frame and the most similar block to the reference one is found in the subsequent frames. material and methods: the program was...

OBJECTIVE A previous pilot series described a hybrid mastoidectomy technique, canal wall window (CWW), which substituted for the canal wall down (CWD) procedure and involved slitting the posterior canal wall. The current, larger series compares the results of the CWW procedure with conventional surgical techniques. STUDY DESIGN Retrospective analysis of 78 pediatric ears. SETTING Academic t...

The important objective of a building must be to provide comfortable environment for people. Heating, ventilation and air conditioning (HVAC) systems environment, but they are using high energy consumption, therefore, designing an energy-efficient that balances performance thermal comfort is necessary. To achieve this subject choose the effective parameters performance. This research aim produc...

With the high density point clouds obtained with terrestrial laser scanning, detailed building facade structures, such as windows, can be recovered. There are usually only a few laser points available for windows, because window frames are small parts on walls, and window glass reflects no laser beam. Insufficient raw laser information makes it very difficult to recover reliable geometry of a w...
