Coding and ordering of fonts based on RHA information language – method. We propose a method for coding and ordering of Roman-type fonts after the distinguished "characteristic" letter H as satisfying the requirements of graphic expression for the ratio of face and proportions of different fonts. The following defining characteristics are highlighted: total area of vertical lines (face strokes), inner free space, horizontal bar area, and outer letter space in a fontwindow. Letter code: a sequence of characters of listed areas by decrease of their shares in a fontwindow, complexity of areas ratio (after C. Shannon) and degree of smallness of small areas (after T. Petrov). Codes are taken for alphanumeric words that are ordered on a special alphabet with automatically obtained hierarchical coding system. This results in a database with a linear ordering of codes and automatic grouping of identical and close ones.

A Free Lunch Proof for Gray versus Binary Encodings

July 1999

Darrell Whitley

A measure of complexity is proposed that counts the number of local minima in any given problem representation. A special class of functions with the maximum possible number of optima is also defined. A proof is given showing that reflected Gray code induce more optima than Binary over this special class of functions; by the No Free Lunch principle, reflected Gray codes therefore induces fewer ... [Show full abstract] optima over all other remaining functions. 1 INTRODUCTION Over all possible functions, Gray codes and Standard Binary codes are equal in that they both cover the set of all possible bit representations [4]. In spite of this No Free Lunch result [5], applications oriented researchers have often argued for the use of Gray codes [1]. The debate as to whether Gray coding is better than Binary representations has been a classic example of where theory and practice clash. The results in this paper bring theory and practice closer together and yields new insights into the role of representati...

Gauge conditions for binary black hole puncture data based on an approximate helical Killing vector

July 2003 · Physical Review D

We show that puncture data for quasicircular binary black hole orbits allow a special gauge choice that realizes some of the necessary conditions for the existence of an approximate helical Killing vector field. Introducing free parameters for the lapse at the punctures we can satisfy the condition that the Komar and ADM mass agree at spatial infinity. Several other conditions for an approximate ... [Show full abstract] Killing vector are then automatically satisfied, and the 3-metric evolves on a timescale smaller than the orbital timescale. The time derivative of the extrinsic curvature however remains significant. Nevertheless, quasicircular puncture data are not as far from possessing a helical Killing vector as one might have expected.

Understanding PoliticalIncentives and Behavior

June 2011

Reviews the types of political actors typically involved in decentralization and focuses on the four most important types of incentive structures that politicians face: electoral, partisan, institutional, and coalitional. Different incentive structures are more or less salient in a particular country depending on regime type. In the growing set of countries where relatively free and fair ... [Show full abstract] elections determine who gains access to decision-making positions within the state, development partners would benefit from paying attention to the electoral dynamics of decentralization. Two dynamics have received special attention: the increasingly common selection of subnational officials via election rather than appointment, and the strategic calculationsthat ambitious politicians make about the likelihood of winning nationalversus subnational elections. Partisan incentives must take into account intra-party dynamics and inter-party dynamics, and institutional incentives are salientdespite differences in regime type. Coalitional incentives may be more difficult to uncover and assess in part because they are less visible than elections, party organizations, and institutions.

Eect of Noise Reduction Using Rough

December 2001

Access to the clinical information content of free text is one of the major challenges facing medical informatics today. In this study we address the problems of automatic classi#cation of chest radiograph reports. For a number of independent categories we assess the e#ectiveness of a K#NN classi#er, and the improvement gained by prior attribute reduction using a technique grounded in rough set ... [Show full abstract] theory. The results suggest that noise reduction using rough set theory can improve the accuracy of classi#cation for some classi#cation categories.
