Common fixed points of generalized almost nonexpansive mappings

Abstract: The concept of a generalized almost nonexpansive mappings is introduced and the existence of common fixed points for this new class of mappings is proved. As an application, an invariant approximation result is obtained.

FPGA Design for Statistics-Inspired Approximate Sum-of-Squared-Error Computation in Multimedia Applications

Abstract: This brief introduces a low-cost hardware design for approximate squaring functions which preserve maximum information content of the signals in template-matching applications. Analysis of signal statistics for two example applications, i.e., motion estimation and disparity estimation, is presented. This information is then specifically incorporated in the hardware design process to develop approximate squarers which outperform existing designs in hardware resource savings and performance while processing real-world data. Specifically, the proposed architectures make distinction between low- and high-entropy portions of the input data to intelligently trade off bit precision with hardware complexity. Mathematical and experimental results show mean-relative-error figures to be as low as 1.2% and the performance to be as good as conventional full-precision processing scenarios. Implementation results for current-generation six-input look up table (LUT) and four-input LUT FPGAs have been discussed in relation to the proposed design flow.

Kyrgyzstan’s Dordoi and Kara-Suu Bazaars: Mobility, Globalization and Survival in Two Central Asian Markets

Abstract: Despite modest economic indicators, Kyrgyzstan boasts two of Eurasia’s largest bazaars: Dordoi bazaar in the capital city Bishkek, and Kara-Suu bazaar in southern Kyrgyzstan. Combined, the 2 bazaars provide employment to approximately 75,000 people and serve as entrepots for foreign merchandise into Central Asia and Russia. This paper makes three arguments: (i) mobility of people, merchandise, capital, and information became a defining feature of the two bazaars after the collapse of the Soviet Union; (ii) Dordoi and Kara-Suu are not static institutions, as bazaars were frequently considered by post-war social sciences. Instead, Dordoi and Kara-Suu are illustrative of Kyrgyzstan’s adaptation to globalization through a transnational commercial web extending between Dubai, Guangzhou, Istanbul, Moscow, Urumchi, and smaller localities in between, making the bazaars uniquely globalized spaces; and (iii) bazaar-based trade was, and remains a critical survival mechanism given the dearth of other vocation...

A Study of the Attitudes and Motivational Orientations of Pakistani Learners Toward the Learning of English as a Second Language

Abstract: In Pakistan where different languages co-exist, and where English has a high status as a second language (L2), the learners’ attitudes toward English plays an important role in formulating effectiv...
