Improve the Active Subspace Method by Partitioning the Parameter Space
The active subspace method is a powerful tool that can be applied in many fields such as uncertainty quantification, inverse problems and optimisation. However, the standard active subspace method constructs an active subspace over the whole parameter space, which makes the method only applicable …

Investigating the parameter space of viable models for f(R) gravity
The accelerated expansion of spacetime intuitively points to the existence of new, unknown energy fields pervading the universe, but it is has also spurred the growth of the research field of modified gravity theories. Of these, f(R) theories of gravity is the first and simplest modification to …

An Approach to 3D Building Model Reconstruction from Airborne Laser Scanner Data Using Parameter Space Analysis and Fusion of Primitives
… point cloud. For each triangle the orientation parameters in space (orientation, slope and perpendicular distance to the barycentre of the laser scanner point cloud) are determined and mapped into a parameter space. As buildings are composed of planar features, primitives, triangles representing …

Analysis of grey level weighted Hough transforms
… Factors which affect transform accuracy include parameter space resolution, image space quantizing errors, parameter space quantizing errors, and Hough space peak detection strategy. One way to improve the accuracy of the transform is to weight each pixel’s Hough space sinusoid by an amount which …

Dark Matter Production after Inflation and Constraints
… a model-independent approach, we explore the parameter space for dark matter with a mass of order MeV and above showing that only small regions of the parameter space for the popular freeze-out mechanism are still viable. Nevertheless, the regions of the parameter space corresponding to the …

Stability of nonlinear oscillatory systems with application to ship dynamics
… a single-degree-of-freedom system in a selected parameter space is developed. The procedure is based on the application of Floquet analysis to determine the stability of second-order perturbation approximations of the solutions of the system in the neighborhoods of specific resonances. As a …

Computational and Experimental Investigation of the Critical Behavior Observed in Cell Signaling Related to Electrically Perturbed Lipid Systems
… Moreover, different values of a PEF pulse parameter, for e.g. the pulse-widths of 100 μs and 100 ns, may have different effects on cell signaling. Thus, the challenge of answering the mechanistic questions is compounded by the large PEF parameter space consisting of different combinations …

Bifurcations in discrete-time neural networks : controlling complex network behaviour with inputs
… can be controlled and particularly which parameter sets cause a specific dynamics. The knowledge of these parameter sets allows to directly switch between different dynamical regimes. In this thesis we develop a general approach to analytically compute the bifurcation manifolds of a RNN, …

An Adjectival Interface for procedural content generation
… models are typically controlled by complex parameters and often require expert technical knowledge. Since people communicate with each other using language, an adjectival interface to the creation of procedural content is a natural step towards addressing the needs of non-technical and …

Nonperturbative quark mass and coupling renormalization in two flavor QCD.
… of Kogut-Susskind quarks is determined over the parameter space of existing lattice (spectrum) simulations from the existing spectrum data. This β function is combined with a series of finite temperature lattice simulations (N(t) = 4) to calculate the interaction measure, ε-3p, which together …

A study of stimulated Brillouin scattering in laser produced plasmas
… laws were developed governing the optimal parameter space for the laser pump beam, probe beam and the plasma amplifier in addition to the ability to control the final amplified pulse characteristics. Optimum regions of parameter space occurring at a density of 0.3nc with pump and seed laser …

Toric mirror symmetry and GIT windows
… of a lattice zonotope in the real character space of the torus. After identifying the ""FI parameter space"" of the B-model GLSM with the GKZ complex parameter space of the skeletal LG A-model, homological mirror symmetry in the quasi-symmetric case becomes two geometric incarnations of the …

A típustér fogalma és tulajdonságai = The Idea and the Features of Type Space
… Hars´anyi suggested the concept of the type space. Later Mertens & Zamir gave a construction of such a type space under topological assumptions imposed on the parameter space. The topological assumptions were weakened by Heifetz, and by Brandenburger & Dekel. In this paper we show that at …
