In this paper, a novel approach for robust automatic optimization of analog circuits with bipolar transistors is presented. It includes additional formal parameters into the device model cards, which sweep the model parameters smoothly between the different device types. In this way, not only the sizing, but also the choice of the device type is committed to the optimization tool, thus improvin...

One of the major challenges in petroleum industry is producing residual oil from underground. One of the major techniques for enhancing oil recovery (EOR) is using gas injection. However, gas has poor volumetric sweep efficiency, this is attributed to its high mobility which considers to be higher compared with oil and water mobility. Several techniques are proposed and applied for reducing gas...

We present a sweep-based approach to modeling and deformation of three-dimensional objects. We approximate the deformable parts of an object using sweep surfaces. The vertices on the object boundary are bound to the sweep surfaces and then follow their deformation. For practical applications, we apply this approach to 3D human body modeling and deformation, and then extend it to the freeform de...

The main aim of this paper is to examine the effectiveness one of the two-stage iterative method known as Half-Sweep Arithmetic Mean (HSAM) method in solving the dense linear systems generated from the discretization of the first and second kinds of linear Fredholm integral equations. In addition, the formulation and implementation of the HSAM iterative method are also presented. Some illustrat...

For solving systems of linear algebraic equations with blockfivediagonal matrices arising in geoelectrics and diffusion problems, the parallel matrix square root method, conjugate gradient method with preconditioner, conjugate gradient method with regularization, and parallel matrix sweep algorithm are proposed and some of them are implemented numerically on multi-core CPU Intel. Investigation ...

This paper investigates the application of the Red-Black Half-Sweep Gauss-Seidel (HSGS-RB) method by using the half-sweep triangle finite element approximation equation based on the Galerkin scheme to solve two-dimensional Poisson equations. Formulations of the full-sweep and half-sweep triangle finite element approaches in using this scheme are also derived. Some numerical experiments are cond...

The interval join is a basic operation that finds application in temporal, spatial, and uncertain databases. Although a number of centralized and distributed algorithms have been proposed for the efficient evaluation of interval joins, classic plane sweep approaches have not been considered at their full potential. A recent piece of related work proposes an optimized approach based on plane swe...

In this study, the aerodynamic performance of flapping wings using a parallel motion was investigated and compared with insect-like “fan-sweep” motion, effect adding slit to analyzed. First, numerical simulations were performed analyze wing aerodynamics two motions equivalent stroke amplitudes over range pitching angles based on computational fluid dynamics (CFD).
