the current study examined iranian undergraduate efl students’ willingness to communicate with regard to their vocabulary knowledge. in general, participants were somewhat willing to communicate in english. the total mean score of 730 university students’ perception of willing to communicate was 83.53 out of 135. results, regarding four parts of willingness to communicate, revealed that part...
this study attempted to explore if teaching english collocations through two different modes of awareness-raising and input flooding has any possible differential effect on immediate retention as well as retention in a delayed assessment. it also compared the possible differential effect of teaching english collocations implicitly and explicitly on actively using the items in writing. m...
We consider the problem of inferring the underlying graph using samples from a Markov random field defined on the graph. In particular, we consider the special but interesting case when the underlying graph comes from a distribution on sparse graphs. We provide matching upper and lower bounds for the sample-complexity of learning the underlying graph of a hard-core model, when the underlying gr...
to test for “randomness” in spatial point patterns, we propose two test statistics that are obtained by “reducing” two-dimensional point patterns to the one-dimensional one. also the exact and asymptotic distribution of these statistics are drawn.
background: the main threats to human health from heavy metals are associated with exposure to plumb (pb), cadmium, mercury, and arsenic. some hazards that threat human health are the results of environmental factors and the relevant pollutions. some important categories of diseases including (cancers) have considerable differences in various places, as observed in their spatial prevalence and ...
Automatic generation of distribution system diagrams is an important aid for the distribution system planner and operator alike for easy visualization of the system. Since a Radial distribution system has a tree structure, what we need to develop is essentially a tree drawing algorithm. In addition,we aim to generate a distribution system graph that is aesthetically pleasing. We define a new se...
The structure of public spaces, particularly, the religious sites of Iran in the Islamic era follow the teachings and principles of Islam. Hosseinieh buildings are among the most significant of this type of public spaces whose function is related to one of the most significant religious communal rituals, i.e., mourning for the Third Shi‘a Imam. The main purpose of this study is to identify func...
Given a distribution G over labeled bipartite (multi) graphs, G = (W; M; E) where jWj = jMj = n, let L(n) denote the size of the largest planar matching of G (here W and M are posets drawn on the plane as two ordered rows of nodes, an upper and a lower one, and a (w; m) edge is drawn as a straight line between w and m). The main focus of this work is to understand the asymptotic (in n) behavior...
An outerplanar (also called circular, convex, one-page) drawing of an n-vertex graph G is a drawing in which the vertices are placed on a circle and each edge is drawn using one straight-line segment. We derive exact results for the minimal number of crossings in any outerplanar drawings of the following classes of graphs: 3-row meshes, Halin graphs and complete p−partite graphs with equal size...
