A straightforward and computationally efficient Consecutive Cubic Spline (CCS) iterative algorithm is proposed for positioning the planar interface of unstructured geometrical Volume-of-Fluid method in arbitrarily-shaped cells. The CCS a two-point root-finding [1, chap. 2] , designed VOF problem, where volume fraction function has diminishing derivatives at ends search interval. As algorithm, r...

Neural prosthesis has been successfully applied to patients with motional or sensory disabilities for clinical purpose. To enhance the performance of the neural prosthetic device, the electrodes for the biosignal recording or electrical stimulation should be located in closer proximity to target neurons than they are now. Instead of revising the prior implanting surgery to improve the electrica...

This paper describes a new efficient approach for visualizing large hierarchical information. Our technique is based on the connection + enclosure visualization model [1] from which the area division is used for the recursive positioning of nodes, while a node-link diagram is still drawn to present the entire hierarchical structure. We inherit the advantages of Space-Optimized (SO) Tree techniq...

Introduction: Substantive amount of work has been done in modeling and analyzing the scintillation camera system processes including positioning and image formation. The goal of this work is to develop a framework for analyzing performance of nonlinear positioning methods upon construction of a mathematical model of the system. In this study, the photodetector array counts are ...

The spatial organization of cells depends on their ability to sense their own shape and size. Here, we investigate how cell shape affects the positioning of the nucleus, spindle and subsequent cell division plane. To manipulate geometrical parameters in a systematic manner, we place individual sea urchin eggs into microfabricated chambers of defined geometry (e.g., triangles, rectangles, and el...

Obstacle detection is a significant task that an Advanced Driving Assistance System (ADAS) has to perform for intelligent vehicles. In the past decade, many vision-based approaches have been proposed. The majority of them use color, structure and texture features as clues to group similar pixels. However, motion blur generated by the movement of obstacles during exposure is not taken into accou...

The term "robot" refers to a precision mechanical device that is accurately controlled by a computer using intelligent software. The term "robotic assistance" refers to the use of such a device to aid a surgeon in the optimal conduct of a procedure, particularly one requiring specified geometrical relationships. The authors have been exploring the application of robotic assistance in situations...

This letter presents a performance evaluation on the conventional normal distribution transform (NDT) map-based scan matching under presence of occlusion. The LiDAR localization method enables centimeter level accuracy positioning; however, state-of-the-art algorithms do not achieve same when excessive unexpected objects, such as pedestrians or dynamic vehicles, occlude field view LiDAR. Althou...

Abstract The paper presents the results of research on determination accuracy parameter for European Geostationary Navigation Overlay System (EGNOS) positioning a dual set on-board global navigation satellite system (GNSS) receivers. study focusses in particular presenting modified algorithm to determine EGNOS mixed model with measurement weights. mathematical considers weights as function squa...

Introduction: The use of panoramic radiography has shown a remarkable expansion over the past 20 years. Accurate positioning and preparation of patients is needed to avoid image distortion. The aim of this study was to evaluate the common errors on panoramic radiographs taken in the radiology department of Rasht dental school. Materials and Methods: The study sample included 390 digital panoram...
