Internal clock synchronization has been investigated, or employed, for quite a number of years, under the requirement of good upper bounds for the deviation, or accuracy, between a predefined master node M and slaves S1, S2, etc. It has been tacitly assumed that the accuracy range between slaves S1 and S2 was just the same as for the master/ slave. In extensive experimental studies of unicast-b...

Analysis of work of art may be treated as some sort of classification of information: does the work is really artistic or not. This article is an attempt to introduce some classification criteria, though the author understands that the problem is extremely delicate and complicated. Attractiveness of work of art is determined by its proportions. The screen of a computer by itself is a mechanism ...

The present study was conducted to identify nutritional value of Rumex obtusifolius in three phenological stages (vegetative growth, flowering, and maturity). Samples were randomly taken in pastures of Saravan in Rasht, Iran in 2015. After drying and grinding, the chemical compositions of Crude Protein (CP), Crude Fiber (CF), Ether Extract (EE), Total Ash (ASH), Neutral Detergent Fiber (NDF), a...

Purpose – To describe the design methodology and human-centre functionality of the whole arm manipulator (WAM) developed originally at MIT and brought to commercial fruition by Barrett Technology. Design/methodology/approach – The WAM arm is driven by cable-and-cylinder transmissions, which uniquely exhibits zero backlash with low friction and low inertia, endowing the WAM with good open-loop “...

Let G be a simple graph and (G) denote the maximum degree of G. A harmonious colouring of G is a proper vertex colouring such that each pair of colours appears together on at most one edge. The harmonious chromatic number h(G) is the least number of colours in such a colouring. In this paper it is shown that if T is a tree of order n and (T ) n2 , then there exists a harmonious colouring of T w...

The harmonious development of China state-owned enterprise and employees is the essential approach to develop state-owned enterprise. The development of enterprise is the premise of employees’ developments, and only harmonious enterprise can ensure employees’ complete development and bring up better employees. At the same time, employee’s quality decides the development level of enterprise, and...

A graph G(p, q) is said to be odd harmonious if there exists an injection f : V (G) → {0, 1, 2, · · · , 2q − 1} such that the induced function f∗ : E(G) → {1, 3, · · · , 2q − 1} defined by f∗(uv) = f(u) + f(v) is a bijection. A graph that admits odd harmonious labeling is called odd harmonious graph. In this paper, we prove that shadow and splitting of graph K2,n, Cn for n ≡ 0 (mod 4), the grap...
