let g(v,e) be a graph with p vertices and q edges. a graph g is said to have an odd mean labeling if there exists a function f : v (g) → {0, 1, 2,...,2q - 1} satisfying f is 1 - 1 and the induced map f* : e(g) → {1, 3, 5,...,2q - 1} defi ned by f*(uv) = (f(u) + f(v))/2 if f(u) + f(v) is evenf*(uv) = (f(u) + f(v) + 1)/2 if f(u) + f(v) is odd is a bijection. a graph that admits an odd mean lab...

A four-quadrant CMOS analog multiplier is presented. The device is nominafly biased with +5-V supplies, has identicaf full-scafe single-ended x and y inputs of +4 V, and exhibits less than 0.5 percent Manuscript received March 1, 1987; revised July 18, 1987.

T latest release of Maple V has had little time to be installed on many University teaching networks, least of all my own! So this review is mainly a report on what the improvements and the new features may have the potential to offer for those contemplating making the upgrade from Release 4, or as a change of teaching software for those who use one of its competitors. For certain comparative p...

This paper describes the 5dpo-2000 team. The paper will be divided into three main sections, corresponding to three main blocks: the Global Level, the Local Level and the Interface. These Levels, their subsystems and some implementation details will be described next.

Of my own situation I wrote: “In one day I typically receive 5-10 pieces of regular junk mail, 15-25 regular letters, 5 pieces of campus mail, 5 reports or documents (not all technical), 5-10 incoming phone calls, 10-20 local electronic messages, and 10-20 external electronic messages. Although many of these messages are discarded or forwarded to others for handling, much of my time is required...

In this paper we study the spectrum of super–simple (v, 5, 2)– designs. We show that a super–simple (v, 5, 2)–design exists if and only if v ≡ 1 or 5 (mod 10), v 6= 5, 15, except possibly when v ∈ {75, 95, 115, 135, 195, 215, 231, 285, 365, 385, 515}.

In the present study, dormancy and germination requirements were investigated in seeds of Citrullus colocynthis (L.). Seeds were subjected to 10 pretreatments in the present study.  These pretreatments included hot water (100° C) followed by the seeds placed between double layered filter paper moistened with 5 ml of distilled water and kept at 28 - 30 °C, sulphuric acid (98% v/v), for 30 min fo...

Super-simple designs are useful in constructing codes and designs such as superimposed codes and perfect hash families. Recently, Gronau et al determined the existence of super-simple (v, 5, 2)-BIBDs with possible exceptions of v ∈ {75, 95, 115, 135, 195, 215, 231, 285, 365, 385, 515}. In this article, we investigate the existence of a super-simple (v, 5, 4)-BIBD and show that such a design exi...
