background: malocclusion, as a worldwide issue, can cause a lot of problems for patients. panoramic (pr) and lateral cephalometric (lcr) radiographs are both usually indicated for orthodontic treatments. the aim of this study was to analyze vertical and sagittal parameters of both jaws on prs and to compare them on lcrs. materials and methods: in this cross sectional study, 61 samples from all ...

let r be a right gf-closed ring with finite left and right gorenstein global dimension. we prove that if i is an ideal of r such that r/i is a semi-simple ring, then the gorensntein flat dimensnion of r/i as a right r-module and the gorensntein injective dimensnnion of r/i as a left r-module are identical. in particular, we show that for a simple module s over a commutative gorensntein ring r, ...

We propose a computational theory of internal-state estimation for others, which is the basis of information processing in human communication. To estimate internal states of the other equivalent to the self, we have to deal with two substantial difficulties, restriction of the estimator’s parameter dimension and conversion between objective and subjective information. The proposed computationa...

The recent years have seen a considerable increase in the number of cluster systems. These systems provide a very good performance-cost ratio. However, in order to meet the requirements for ever-increasing computing power of present day applications, several SMP cluster systems have emerged. By deploying two or more processors per workstation can increase the performance of a cluster significan...

In this paper, we propose visualization for mass information in the social network with a holistic view, which focused on representing the effect of user communication. With the Rapid Expansion of social network, it is necessary to provide a holistic view to the users and researchers to understand the effect of information communicated in the network. The social network users will be visualized...

this study focused on the effect of teaching collocations on the awareness of two affective dimensions, evaluation and potency dimensions, of deep vocabulary knowledge as well as the general vocabulary knowledge of efl students. sixty intermediate efl female adult learners participated in this study; they were chosen among 90 students through the pet and a general vocabulary knowledge test. the...

The application of the principles of quantum mechanics to cryptography has led to a respectable new dimension in confidential communication. As a result of these developments, it is now possible to construct cryptographic communication systems which detect unauthorized eavesdropping should it occur, and which give a incontestable guarantee of no eavesdropping should it not occur. Here several p...

There has been relatively little research on consumer usage of text messages and Instant Messenger, whilst mobile phones and email usage have been more widely addressed. This study compares consumer usage of four communication channels: Instant Messenger, text messages, mobile phones and email, with the focus on consumer choice of communication medium. This research used grounded theory and foc...

Let $G$ be a simple connected graph. In this paper, Szeged dimension and PI$_v$ dimension of graph $G$ are introduced. It is proved that if $G$ is a graph of Szeged dimension $1$ then line graph of $G$ is 2-connected. The dimensions of five composite graphs: sum, corona, composition, disjunction and symmetric difference with strongly regular components is computed. Also explicit formulas of Sze...
