Precise localization of the third molars in relation to the inferior alveolar nerve canal is critical from a clinical point of view and strongly affects the surgical treatment outcome. Recently, by using three-dimensional modeling software, the relationship of third molar root apices and inferior alveolar nerve canal can be better understood. In this study, the spatial relationship of two surgi...

A new three-dimensional unit cell model has been developed for modeling three constituent phases including inclusion, interphase and matrix. The total elastic modulus of nano-composite is evaluated.  Numerical results are in good agreement with the previous proposed theoretical modeling. Higher matrix and inclusion elastic modulus both can dramatically influence the total elastic modulus.

Shape matching plays an important role in many application fields. In this paper, we propose a novel rotation invariant 3D shape descriptor based on Hadamard transform and spherical harmonic transform. In our method, a 3D model is represented as a collection of spherical functions to preserve shape information as much as possible, and the shape similarity is directly defined by the difference o...

90 LLE Review, Volume 82 Introduction To achieve ignition and gain in inertial confinement fusion (ICF), a spherical target must be compressed with a highly uniform drive mechanism.1–3 Perturbations in the drive can lead to a distorted fuel core as well as hydrodynamic instabilities, which cause the colder ablator material to mix with the fuel in the central hot spot, effectively quenching the ...

Direct manipulation is the operation in which users' operations directly invoke the reaction of the system (Shneiderman 1986). We apply the direct manipulation technique to operate a three-dimensional object. Some works on editing a three-dimensional object by using the direct manipulation technique have been proposed. But they require a special input device. We think it is beneficial to make u...

Mining subsidence associated with longwall extractions beneath significant natural features such as rivers and streams in the Southern Coalfield of New South Wales has posed risks to the natural environment. In this paper, a case study is presented showing the methodology in two-dimensional UDEC (Itasca 2006) modeling for mining induced subsidence around river valley, taking advantage of the di...

This paper describes a database of 11 dependency treebanks which were unified by means of a two-dimensional graph format. The format was evaluated with respect to storage-complexity on the one hand, and efficiency of data access on the other hand. An example of how the treebanks can be integrated within a unique interface is given by means of the DTDB interface.

In this paper we try to clarify the confusions that lie around the widely used terms “analysis model” and “design model” in software engineering. In our experience, these confusions are the root of some difficulties that practitioners encounter in system modeling, and sometimes lead to bad engineering practices. Our approach consists of placing the duality of analysis and design within a three-...

There is a striking increase in the availability of statistical data in the Linked Open Data (LOD) cloud, and the Cube vocabulary has become the de facto standard for the description of multi-dimensional data. However, the reuse of a standard vocabulary needs to pair with modeling strategies that make it easy to locate, consume and integrate information. In this paper, we developed a quantitati...
