The Importance of Graphs in Undergraduate Physics then a mistake has been made and should be corrected. This is a good reason for graphing as the data are being taken. To discover that there is no correlation between the plotted quantities may be an important result in a research project. At the introductory level, it might occur if a student plots the wrong variables or even performs the wrong...

One of the psychological variables which may have a long-lasting effect on our life is labeling, and students’ accomplishments might be severely undermined through the teacher’s labeling. In spite of this issue, few studies have been carried out on the ramifications of labeling in the educational contexts, in general, and EFL classrooms, in particular. The current study is an attempt to investi...

background: the purpose of study was to evaluate and compare chemical quality of iranian bottled drinking water reported on manufacturer's labeling and standards. methods: this study was a cross-sectional descriptive study and done during july to december 2008. the bottled mineral water collected from shops randomly were analyzed for all parameters address on manufacturer's labeling and the res...

let g=(v,e) be a simple graph. an edge labeling f:e to {0,1} induces a vertex labeling f^+:v to z_2 defined by $f^+(v)equiv sumlimits_{uvin e} f(uv)pmod{2}$ for each $v in v$, where z_2={0,1} is the additive group of order 2. for $iin{0,1}$, let e_f(i)=|f^{-1}(i)| and v_f(i)=|(f^+)^{-1}(i)|. a labeling f is called edge-friendly if $|e_f(1)-e_f(0)|le 1$. i_f(g)=v_f(1)-v_f(0) is called the edge-f...

In this paper we define a new labeling called skolem odd difference mean labeling and investigate skolem odd difference meanness of some standard graphs. Let G = (V,E) be a graph with p vertices and q edges. G is said be skolem odd difference mean if there exists a function f : V (G) → {0, 1, 2, 3, . . . , p + 3q − 3} satisfying f is 1−1 and the induced map f : E(G) → {1, 3, 5, . . . , 2q−1} de...

The Measure Components feature of the MSA (Transmission mode, menu AnalysisMeasure Components) is intended for measuring values of resistors, capacitors and inductors. The MSA automatically chooses an appropriate frequency between 100 kHz and 40 MHz for the measurement. This is not as complete or precise as graphing the component value in Reflection mode, which can show the behavior of the com...

High-level Petri nets are a graphical language for the modeling of distributed information systems. Petri nets can be validated by simulation. In this paper, a technique is proposed which generates test cases for the simulation of high-level Petri nets in a systematic way. The approach is called cause-effect-net-concept and is derived from a program code testing concept, the so-called cause-eff...
