A new cosmological model provides solutions for the flatness, smoothness, monopole, and classical singularity problems, with no adjustment of parameters. The prediction of a scale factor R (t) which is proportional to t (rather than t) yields a comfortably large age for the universe, and also implies that the deceleration parameter q0 is exactly zero.

A novel, automatic tertiary classifier is proposed for identifying vegetation, building and non-building objects from a single nadir aerial image. The method is unsupervised, that is, no parameter adjustment is done during the algorithm’s execution. The only assumption the algorithm makes about the building structures is that they have convex rooftop sections. Results are provided for two diffe...

In this paper, a new adjustment to the damping parameter of the Levenberg-Marquardt algorithm is proposed to save training time and to reduce error oscillations. The damping parameter of the Levenberg-Marquardt algorithm switches between a gradient descent method and the Gauss-Newton method. It also affects training speed and induces error oscillations when a decay rate is fixed. Therefore, our...

This paper proposes a mixed integer programming model to solve a non-identical parallel machine (NIPM) scheduling with sequence-dependent set-up times and human resiliency engineering. The presented mathematical model is formulated to consider human factors including Learning, Teamwork and Awareness. Moreover, processing time of jobs are assumed to be non-deterministic and dependent to their st...

In volume visualization interfaces, renderingrelated parameters are often manually editable through various controls and interface elements. Most of the time however, these offer little or no beforehand information on the resulting effects that would occur for certain parameter values or across the whole value domain. This makes parameter adjustment a trial and error process. We have developed ...

SUMMARY Adjustment of a certain parameter in the course of performing a trajectory task such as drawing or gesturing is a common manipulation in pen-based interaction. Since pen tip information is confined to x-y coordinate data, such concurrent parameter adjustment is not easily accomplished in devices using only a pen tip. This paper comparatively investigates the performance of inherent pen ...

An adjustment scheme for the relaxation parameter of interior point approaches to the numerical solution of pointwise state constrained elliptic optimal control problems is introduced. The method is based on error estimates of an associated finite element discretization of the relaxed problems and optimally selects the relaxation parameter in dependence on the mesh size of discretization. The f...

During a medical radioscopic examination, the X-ray dose needs to be adjusted continuously to the body region examined. In current systems, this adjustment is based on the mean grayvalue of the central part of the current image. Basing the control of the X-ray dose on this parameter alone leads to incorrect exposure, if direct radiation enters the central part of the image. We present the appli...

Aiming at the parameter optimization of least square support vector machine (LS-SVM), an improved quantum-behaved particle swarm optimization (IQPSO) algorithm for LS-SVM parameter selection was proposed. Based on QPSO, the algorithm optimizes particle initializing positions and improves solving speed and precision by sampling and linearizing methods. IQPSO LSSVM model was test by test function...
