In the last two years, OpenMP has been gaining popularity as a standard for developing portable shared memory parallel programs. With the improvements in centralized shared memory technologies and the emergence of distributed shared memory (DSM) architectures, several medium-to-large physical and logical shared memory con gurations are now available. Thus, OpenMP stands to be a promising medium...

In this paper, in terms of the concentration of an aqueous solution of a surfactant, we investigate the self-assembly behavior of a porphyrin, 5, 10, 15, 20-tetra(4-pyridyl)-21H, 23H-porphine [H2TPyP], by using an oil/water system as the medium. We find that when a chloroform solution of H2TPyP is dropwise added into an aqueous solution of cetyltrimethylammonium bromide [CTAB] with a lower conc...

1. Abstract Topology optimization yields an overall layout of a structure in the form of discrete density (e.g., SIMP) or continuous boundary geometry (e.g., level-set method). One of important drawbacks, however, is that it leads to a geometry with zigzag boundaries and/or irregular shapes, which is difficult to be interpreted for manufacturability, as well as to be utilized in subsequent appl...

In the present paper we study the geometric properties of the multivalued solutions to the eikonal equation and we give the appropriate classification theorems. Our motivation stems from geometrical optics for approximating high frequency waves in stratified media. We consider the case of a fixed Hamiltonian imposed by the medium, and we present the geometric framework that describes the geomet...

The authors present a case of a neuroendocrine carcinoma in an asymptomatic 75-year-old woman, detected in routine breast screening. The lesion was visible at mammography as a well circumscribed, medium density nodule, with no associated microcalcifications, and at ultrasonography as a hypoechoic nodule, with irregular shape and ill-defined margins. Magnetic resonance imaging revealed findings ...

In this paper, we propose a B-Spline Offset Feature (BSOF) for feature-driven topology optimization. The feature is inspired from the geometric morphology of worms characterized by an elongated cylindrical, bilaterally symmetric, and well-segmented body along highly deformable directrix. B-spline used to define directrix with its outward inward offsets outlining BSOF. This definition endows BSO...

3D object classification has attracted appealing attentions in academic researches and industrial applications. However, most existing methods need to access the training data of past classes when facing common real-world scenario: new objects arrive a sequence. Moreover, performance advanced approaches degrades dramatically for learned (i.e., catastrophic forgetting), due irregular redundant g...
