The interplay between a mobile target and a dynamic multileaf collimator can compromise the accuracy of intensity-modulated radiation therapy (IMRT). Our goal in this study is to investigate the dosimetric effects caused by the respiratory motion during IMRT. A moving phantom was built to simulate the typical breathing motion. Different sizes of the gating windows were selected for gated delive...

In this paper, we propose a joint optical flow and principal component analysis (PCA) method for motion detection. PCA is used to analyze optical flows so that major optical flows corresponding to moving objects in a local window can be better extracted. This joint approach can efficiently detect moving objects and more successfully suppress small turbulence. It is particularly useful for motio...

Contrary to MON-tree index less than the temporal and spatial indexing methods based on road networks we proposed Improved-MON-tree. The index is divided into two levels and the quad tree grid index at the top of the road network, and the bottom of the two-dimensional Rtree index moving object moving information. In order to support the global trajectory of moving objects query, add a hash stru...

(Speotyto cuniculuria) to a moving object when the object did and did not cast a conspicuous shadow. We used a single Burrowing Owl for all tests. It was trapped about 5 km north of Davis, Yolo County, California. We chose this species because it is easily trapped and because it often feeds nocturnally upon terrestrial prey, including rodents, and therefore may exploit shadow cues (Thomsen, Con...

Rectification and reactive distillation columns are the main of all units in petrochemical refining industry. Soft sensors consist mathematical models that estimate quality an output product real time used for technological processes control. In general, changes composition raw materials, catalyst deactivation, etc. result inconsistency between obtained data current state process. sensor design...

This work presents a methodology that relies on the application of radial basis functions network (RBF)-based feedback control algorithms to pharmaceutical crystallization process. Within scope model-based evaluation proposed strategy, firstly strategies for data treatment, structure and training methods reflecting possible scenarios in industry (Moving Window, Growing Window Golden Batch strat...

In this research, we present an improved version of Bidirectional (BD) exact pattern matching (EPM) algorithm to solve the problem of exact pattern matching. Improved-Bidirectional (IBD) exact pattern matching algorithm introduced a new idea of scanning partial text window (PTW) as well with the pattern to take decision of moving pattern to the right of partial text window. IBD algorithm compar...

A growing number of studies in vision research employ analyses of how perturbations in visual stimuli influence behavior on single trials. Recently, we have developed a method along such lines to assess the time course over which object velocity information is extracted on a trial-by-trial basis in order to produce an accurate intercepting saccade to a moving target. Here, we present a simplifi...
