In this paper, a method based on binary-coded genetic algorithm is proposed to explore an optimization method, for obtaining an optimal elliptical tank. This optimization method enhances the rollover threshold of a tank vehicle, especially under partial filling conditions. Minimizing the overturning moment imposed on the vehicle due to c.g. height of the liquid load, lateral acceleration and ca...

Varian Medical Systems (Palo Alto, CA) has implemented the Monte Carlo electron dose calculation algorithm (eMC) in the Eclipse treatment planning system. Previous algorithms for electron treatment planning were limited in their calculation ability for small field depth doses and monitor units. An old rule of thumb to approximate the limiting cutout size for an electron field was determined by ...

This paper presents thermal buckling analysis of rectangular functionally graded plates (FG plates) with an eccentrically located elliptic cutout. The plate governing equations derived by the first order shear deformation theory (FSDT) and finite element formulation is developed to analyze the plate behavior subjected to a uniform temperature rise across plate thickness. It is assumed that the ...

This study explored the free vibration problem in relation to glass fiber reinforced polymer (GFRP) plates with central cutouts and free boundaries using theoretical, experimental, and numerical methods. The theoretical formulations were derived from the classical lamination plate theory. The rectangular cutout was mathematically modeled into the stiffness matrix of the plate by multiplying Hea...

Quasi-bound states in the continuum (QBICs) are Fano resonant with long optical lifetimes controlled by symmetry-breaking perturbations. While conventional responses limited to linear polarizations and do not support tailored phase control, here we introduce QBICs born of chiral perturbations that encode arbitrary elliptical polarization enable geometric engineering. We thereby design metasurfa...

This paper presents a system for an efficient image segmentation on mobile phones using multi-level graph cut. As the computational capacity of mobile devices is often limited, a fluent and smooth image segmentation is a challenging task with existing segmentation algorithms, increased in difficulty by mobile phone cameras continually upgraded to take photos of higher resolution. Our solution i...

Large C and C++ softwa¡e projects typically share common types, macros, and variables among modules via include files organized into hierarchies. Many of these hierarchies grow so complex that it is haed for programmers to figure out when a file must be included. Since including unused symbols is usually harmless, application code tends to include more files than required. Knowing when ñles are...

We present a stochastic Petri net model of a replicated file system in a distributed environment where replicated files reside on different hosts and a voting algorithm is used to maintain consistency. Witnesses, which simply record the status of the file but contain no data, may be used in addition to or in place of files to reduce overhead. We present a model sufficiently detailed to include ...

A modularization is a partitioning of a software system into components based on a variety of criteria, each depending on the clustering approach and desired level of abstraction. Source-header dependency graphs are bipartite graphs that are formed by flattening include file dependencies and enumerating source file to header file dependencies. In this paper, we describe an approach for identify...

The increasing trendof constructing componentsmade of composite laminates is due tothe flexibility intailoring their properties and high strength-to-weight ratio. Nevertheless, most practical components involve cutout features for fastening these cutouts could significantly reduce the strength laminate. Due to its importance, many studies were conducted study effect circular however, there lack...
