The Beard-Maxwell reflection model is presented as a new local reflection model for use in realistic image synthesis. The model is important because there is a public domain database of surface reflection parameters, the Nonconventional Exploitation Factors Data System (NEFDS), that utilizes a modified form of the BeardMaxwell model. Additional surface reflection parameters for the database can...

Abundance calculations for the p-nuclei involve an extended network of about 20,000 nuclear reactions of almost 2,000 nuclei. These rates are calculated with the statistical Hauser Feshbach Model (HF-Model). Elastic scattering experimental data provides a test for the global parameterizations of optical potentials that are used in these statistical model calculations. Recent experiments suggest...

This paper presents a statistical approach to aggregating speed and phase (directional) information for vascular segmentation in phase contrast magnetic resonance angiograms (PC-MRA), and proposes a Maxwell-Gaussian finite mixture distribution to model the background noise distribution. In this paper, we extend our previous work [6] to the segmentation of phase-difference PC-MRA speed images. W...

Standard linguistic analysis of syntax uses the T-model. This model requires the ordering: D-structure > S-structure > LF, where D-structure is the sentences deep structure, S-structure is its surface structure, and LF is its logical form. Between each of these representations there is movement which alters the order of the constituent words; movement is achieved using the principles and parame...

Performing fast and accurate methods for modeling the electrical machines has been the subject of several studies and many authors proposed different procedures to attain this aim. Beside the accuracy, the speed of the method is of great concern. On the other hand, the capability of the method to be changed according to the need is another important issue. Finite Element method provides relativ...

one of the most important factors that affect tire friction is surface roughness, which determines the size of the real contact area, real pressure distribution on the contact interface, and scales of mechanical engagement between viscoelastic rubber and a rough substrate. the need to predict coefficient of friction (cof) for rubber on rough surfaces for applications such as traction of tires o...

introduction: diabetes is the most common disease related to metabolism disorders with long term complications. it needs lifelong specific self-care, as it causes a promotion in quality of life and decreases disease costs. the health belief model (hbm) is a psychological model that attempts to explain and predict health behaviors. this is done by focusing on the attitudes and beliefs of individ...

This paper presents an extended multicomponent lattice Boltzmann model for the simulation of electrolytes. It is derived by means of a finite discrete velocity model and its discretization. The model recovers momentum and mass transport according to the incompressible Navier-Stokes equation and Maxwell-Stefan formulation, respectively. It includes external driving forces (e.g., electric field) ...
