The efficiency and economical performance of sewer systems is an essential issue in urban drainage. The need for sewers to carry sediment has been recognized for many years. One of the main problems in designing sewerage systems is the sediment deposition. Sedimentation in sewers occurs regularly according to the alternating natural flow. The present study investigates the hydraulic characteris...

Traditional planning method for orthognathic surgery has limitations of cephalometric analysis, especially for patients with asymmetry. The aim of this study was to assess surgical plan modification after 3-demensional (3D) simulation. The procedures were to perform traditional surgical planning, construction of 3D model for the initial surgical plan (P1), 3D model of altered surgical plan afte...

Feature-scale simulation of sputter etching has been coupled to equipment parameters by means of transferring angular distributions of ions as provided by equipment simulation to our simulation code. Etching is modeled by performing ion flux integration for all node positions on a discretized 3D surface, taking into account shadowing by the geometry, the angular distribution of ions, and the sp...

PURPOSE To evaluate the effect of the simulation method on recurrence among the patients who received radiotherapy after breast-conserving surgery (BCS) for early breast carcinoma. MATERIALS AND METHODS Between 1995 and 2000, 70 patients with stage I-II breast carcinoma underwent breast-conserving surgery and adjuvant radiotherapy. Twenty nine patients (41.4%) were simulated with the 2D conto...

State of the art 3D simulation applications like virtual testbeds for space robotics, industrial automation or even forest inventory require a highly flexible but still real-time capable data management system. For this, we combine a high-performance internal simulation database with external object-oriented databases into a new real-time capable data management architecture for database-driven...

Displaying facial motions such as crying or laughing is difficult to achieve in real-time simulations and games. Not only because of the complicated simulation of the physical characteristics such as muscle motions or fluid simulations, but also because one needs to know how to control these motions on a higher level. In this thesis, we propose a method that is an extension of the MPEG-4 Facial...

A 3-dimensional particle simulation code is developed to study the photoelectron cloud in positron rings. The effects of the various magnetic fields in KEKB LER are presented. The distribution and evolution of the electron-cloud are simulated.

-The digital creation of cloud is important for many applications in computer graphics, including outdoor simulations and the digital rendering of atmospheric effects. Unfortunately, it is still difficult to simulate realistic cloud with interactive frame rates due to its peculiar microstructures and complex physical process of formation. Realistic simulation of cloud turns to be one of the mos...
