jachymski [ proc. amer. math. soc., 136 (2008), 1359-1373] gave modified version of a banach fixed point theorem on a metric space endowed with a graph. in the present paper, (g, φ)-graphic contractions have been de ned by using a comparison function and studied the existence of fixed points. also, hardy-rogers g-contraction have been introduced and some fixed point theorems have been proved. s...

The Kuratowski and Ryll-Nardzewski selection theorem is a classical of measure theory that gives sufficient condition for multifunction to have measurable selection. aim this paper show some generalizations result.

Abstract  In his paper a new current-controlled conveyor (CCCII) in CMOS technology is presented. It features, low supply voltage (±0.7), low power consumption, low circuit complexity, rail to rail operation and wide range parasitic resistance ( ). The circuit has been successfully employed in a multifunction biquad filter. Simulation results by HSPICE show high performance of the circuit and c...

A new type of thesaurus for word processing is proposed. It comprises 7 semantic and 8 syntagmatic types of links between Russian words and collocations. The original version now includes ca. 76,000 basic dictionary entries, 660,000 semantic and 292,000 syntagmatic links, English interface, and communication with any text editor. Methods of delivery enriching are used based on generic and synon...
