This paper presents a shape matching framework based on a new shape decomposition approach. A new region-based shape descriptor is proposed to compute the best match between given 2D or 3D shapes. In order to find similar shapes in a database, we first split the interior of each shape into the adequate set of parts, classes, or ellipsoids, then find the corresponding parts between different sha...

introduction: controversy remains as to the advantages and disadvantages of pharyngeal packing during septorhinoplasty. our study investigated the effect of pharyngeal packing on postoperative nausea and vomiting and sore throat following this type of surgery or septorhinoplasty.   materials and methods: this clinical trial was performed on 90 american society of anesthesiologists (asa) i or ii...

brass ferrules have been used as packing in a laboratory- scale glass distillation column approaching pilot plant size because of their availability in all sizes and low cost. the available size range is such that these ferrules could also be used in industry and the results of this study could be scaled up. the performance of the new packing has been compared with the performance of glass pack...

Proteins are the main working molecules of a cell. Typical protein molecules contain thousands or more atoms and have complex shapes. Understanding how atoms in proteins pack and how they form intricate shape in three dimensional space is an important task, as it helps us to gain insight on how proteins fold and how they carry out biological functions. There exists a large body of work using ge...

The thermal model for transverse heat flow of having single filament in a unit cell is extended. In this model, we proposed that two circular filaments in a unit cell of square packing array and obtained the transverse thermal conductivity of an unidirectional material. I. Thermal Model Predicting equivalent thermal conductivity of transverse flow in unidirectional composite materials is of int...

The problems involved in the automated packing and nesting of irregular shapes are not only of theoretical importance, but have considerable industrial interest. The ability to manipulate objects under visual control is one of the key tasks in the successful implementation of robotic, automated assembly and adaptive material handling systems. Such systems must be capable of dealing with a wide ...

Using probabilistic ideas, we prove that if μ is a mean porous measure on R, then the packing dimension of μ is strictly smaller than n. Moreover, we give an explicit bound for the packing dimension, which is asymptotically sharp in the case of small porosity. This result was stated in [D. B. BELIAEV and S. K. SMIRNOV, “On dimension of porous measures”, Math. Ann. 323 (2002) 123-141], but the p...

Understanding disordered particle packings is of great significance from both theoretical and engineering perspectives. Establishing a quantitative relationship between nonspherical shape packing properties generally challenging, due to the complex geometry topology. Here we resolve this issue by numerically investigating jammed various frictional congruent particles, including superellipsoids ...

The paper described a generalized integrated glance to bin packing problems including a brief literature survey and some new problem formulations for the cases of multiset estimates of items. A new systemic viewpoint to bin packing problems is suggested: (a) basic element sets (item set, bin set, item subset assigned to bin), (b) binary relation over the sets: relation over item set as compatib...
