When the density current smashes into the lower dense fluid mass a plunge region will occur. Since the plunge depth bounds between density current and ambient fluid, determining of this point is important. In this research, the hydraulic parameters of density current and bed slope of stagnant fluid were investigated. To achieve the purpose of this research a physical model was built in the hydraulic laboratory of Shahid Chamran University (SCU) and various experiments were performed. In the experiments, the plunge depth at the different discharge of density current and density difference 6, 9, 13 and 16 kg/m3 at three slopes 8, 12 and 16% was measured. Then using Flow-3D under RNG turbulence model, plunge depth was simulated for the same experimental condition. The comparison of results obtained showed that the predicted plunge depth with Flow-3D under RNG turbulence model had a high and satisfactory accuracy. Finding showed that for the 8% bed slope, the results of RNG turbulence model 14% was more than experimental data. While, for the entire slope, the results of RNG turbulence model was predicted 10.5% in average more than measured data. Generally, the statistical investigations showed that the RNG turbulence model with satisfactory precision estimated the plunge point depth.

A Control Chart can be designed based on heuristic, statistical, economic or economic statistical assumptions. When a control chart such as multivariate cumulative sum (MCUSUM) control chart is employed to monitor a production process, three parameters should be determined; subgroup size, sampling frequency and the control limits. This paper provides an algorithm for economic-statistical designing the PPCUSUM control charts parameters based on simulation approach. Finally, example and sensivity analysis are presented.

Today, countries’ power projection, along with tangible and intangible elements of power, is considered as one of the indicators of national power which through them, a country fulfills its demands by using consequences of power elements. Depending on the amount of this power, the scope and the range of countries’ power projection differs from each other. Although, many international scholars pay attention to the U.S. and Russia’s elements of strength and power projection as the world's greatest military powers, however, the prospect of China’s continuous and increasing economic growth considers the country’s likely increase of power projection.Thus, by viewing the concept of power projection, in this article, we will examine its elements in relation with China and then, with a comparative look, we study China’s power projection at regional and international level.

In this paper, we introduce the notion of normalized distance Laplacian matrices for signed graphs corresponding to the two signed distances defined for signed graphs. We characterize balance in signed graphs using these matrices and compare the normalized distance Laplacian spectral radius of signed graphs with that of all-negative signed graphs. Also we characterize the signed graphs having maximum normalized distance Laplacian spectral radius.

Let $G$ be a simple connected graph of order $n$ with $m$ edges. Denote by $% \gamma _{1}^{+}\geq \gamma _{2}^{+}\geq \cdots \geq \gamma _{n}^{+}\geq 0$ the normalized signless Laplacian eigenvalues of $G$. In this work, we define the normalized signless Laplacian Estrada index of $G$ as $NSEE\left(G\right) =\sum_{i=1}^{n}e^{\gamma _{i}^{+}}.$ Some lower bounds on $%NSEE\left( G\right) $ are also established.

Personification is one of the most important figures of speech that are manifested in poetry in several forms. Personification usually accompanies figures of speech such as ambiguity, pun, simile etc. Personification as a kind of metaphor or simile has got two bases; 'person' and 'thing', i.e. inanimate object. Whenever we attribute a human attribute or activity to or project a spiritual state and human activity into inanimate objects, the result is personification. Personification is one of the most important dimensions of beauty in Hafiz's poetry. Hafiz personified in different ways and in numerous forms and, in fact, his skill in doing so was excellent. The most important devices in Hafiz's personification include simile, metaphor, and ambiguity that occur in the ground of metaphor.

projection and rationalization are among the major problems that people encounter often in daily relationships as common defense mechanisms. The extent of which this problem exists is an indication of certain unpleasant mentality. It is due to undesirable behaviors like denying responsibility, escaping reality, deception and immaculate presentation of oneself; the characteristics which usually take place unconsciously. Since the folklore is the presentation of traditions and social behavior and cultural values, therefore, in this article the attempt is made to trace the indications and instances of these concepts in Iranian folklore and in its subaltern cultures. The instances were found in the folk stories, proverbs and wise sayings. For this purpose first these psychological concepts were defined and explained, and then the instances extracted from the sources were presented. It is necessary to remember that at times certain instances carry both meanings of the projection and rationalization in them simultaneously.
