Optical coherence tomography (OCT) allows imaging dynamic structures and fluid flow within scattering tissue, such as the beating heart and blood flow in murine embryos. For any given system, the frame rate, spatial resolution, field-of-view (FOV), and signal-to-noise ratio (SNR) are interconnected: favoring one aspect limits at least one of the others due to optical, instrumentation, and softw...

urban design problems have become so complex that no single designer is able to consider all aspects of a design area simultaneously. lately the application of computerized and scientific methods have helped designers analyze complex problems. one of these new methods is space syntax. the purpose of this study is to first investigate the strengths and weaknesses of this method and then suggest ...

of “From Pixels to Layers: Joint Motion Estimation and Segmentation” by Deqing Sun, Brown University, May 2013 Estimating image motion, or optical flow, in scenes with multiple moving objects and segmenting the individual moving objects are two fundamental problems in computer vision and have applications in many fields, including medical imaging, image processing, graphics, and robotics. Motio...

The measurement of spatial segregation has often used measures such as the Neighborhood Sorting Index (NSI) or the Index of Dissimilarity (D) that do not take full account of space. We propose a Generalized Neighborhood Sorting Index (GNSI), an extension of NSI, in which each neighborhood is part of a broader community, the extent of which can be easily changed by increasing the order of contig...

Abstract The free surface at an air–water interface can provide information regarding bathymetric complexities, as well the subsurface flow. We present a comparison of performance two recent advances in light-based optical techniques for measurements, total internal reflection-deflectometry and moon-glade background-oriented schlieren, with more established method synthetic schlieren. make use ...

An extensive allozyme survey was conducted within a natural "meta" population of the native North American annual legume, Chamaecrista fasciculata (Leguminosae) to quantify genetic structure at different spatial scales. Gene flow was then estimated by a recently developed indirect method based on a continuous population model, using pairwise kinship coefficients between individuals. The indirec...

This paper presents a hybrid approach for developing radiation plans for high dose rate brachytherapy in cancer treatment. In order to take care of the computationally hard dose volume constraints, linear programming (LP) is alternated with heuristic neighborhood search which allows for a quick generation of multiple feasible treatment plans. The simulated annealing neighborhood search is guide...

Practical concept of velocity distribution of pressure flow in the bends is interesting and hence, the professional engineering design has been investigated in the current study. This paper shows that velocity distribution in the bends can be analyzed in terms of the probability distributions. The concept of entropy based on the probability is an applied and new approach to achieve velocity pro...
