Rough music, rough dance, rough play : misrule and Morris dance
… display of misrule by E.P. Thompson titled "Rough Music" (1993). Using the research that has emerged from the study of carnival behaviour by Mikhail Bakhtin and liminality by Victor Turner, the basic conditions of misrule are reviewed and illuminated. Then the symbols and behaviour of modern …

Rough Hewn
Rough Hewn is the culmination of my research into aesthetics and form. It is a reflection of my appreciation of the raw surface textures and shapes that can be captured in wood; the "How?" and "What If?" of the objects, materials, and processes that inform my creative development. As I compose my …

Rough volatility models
So-called rough stochastic volatility models constitute the latest advancement in option price modeling. In contrast to popular bivariate diffusion models such as Heston, here the driving noise of volatility is modeled by a fractional Brownian motion (fBM) with scaling in the rough regime of Hurst …

Rough Surface Scattering and Propagation over Rough Terrain in Ducting Environments
The problem of rough surface scattering and propagation over rough terrain in ducting environments has been receiving considerable attention in the literature. One popular method of modeling this problem is the parabolic wave equation (PWE) method. In this method, the Helmholtz wave equation is …

Structured Rough Set Approximations
Rough set theory is widely used in many areas, such as artificial intelligence, machine learning and data mining. Lower and upper approximations are two fundamental notions for concept analysis with rough set theory. In rough set theory, one can obtain two kinds of sets in an information table, …

Reducts and Rough Set Analysis
Rough set theory offers a mathematical approach to data analysis and data mining. It can be used to learn classification rules that define classes of a classi- fication based on some well defined concepts. The fundamental task of rough set data analysis is to precisely construct and interpret …

Turbulent Flow Over Rough Surfaces
… flow structure in repeated-rib geometry rough-walled surfaces in two size pipe systems as a function of the ratio of roughness height to spacing distance between the elements (P/K), the axial variation of the flow, and the flow rates. The variations in P/K geometries caused the flow …

Empirical analysis of rough set categorical clustering techniques based on rough purity and value set
… categorical data and handling uncertainty, the rough set theory has become well-established mechanism in a wide variety of applications including databases. The recent techniques such as Information-Theoretic Dependency Roughness (ITDR), Maximum Dependency Attribute (MDA) and Maximum …

Optimizing Rough Set Flow Graph Inference
… good elimination orderings in BN inference. Rough sets are another tool for managing uncertainty. The basic idea of rough set theory is to approximate an undefinable set by two definable sets, called upper and lower approximations. Rough set ow graphs (RSFGs), introduced by Pawlak, are a …

Asymptotics of the Rough Heston Model
The recent explosion of work on rough volatility and fractional Brownian motion has led to the development of a new generation of stochastic volatility models. Such models are able to capture a wide range of stylised facts that classical models simply do not. While these models have sound …

Sound from Rough Wall Boundary Layers
Turbulent flow over a rough surface produces sound that radiates outside the near wall region. This noise source is often at a lower level than the noise created by edges and bluff body flows, but for applications with large surface area to perimeter ratios at low Mach number, this noise source can …

Velocity distribution in steep rough channel
… in a steep rectangular channel with artificial roughness elements. Four shapes of roughness elements, rectangular, parallelogram, triangular, and semi-circular, were used. Effects on velocity distribution due to variations in discharge, flume slope and roughness geometry were studied for each …

Pneumonia Detection with Game-Theoretic Rough Sets
… we employ three-way classification, supported by rough sets, to interpret the doubtful X-ray images that lack complete information. The training set of X-ray images is divided into three distinct regions based on testing and test-treatment thresholds. This threshold pair determines the decision of …
