A signed graph is a graph where the edges are assigned either positive ornegative signs. Net degree of a signed graph is the dierence between the number ofpositive and negative edges incident with a vertex. It is said to be net-regular if all itsvertices have the same net-degree. Laplacian energy of a signed graph is defined asε(L(Σ)) =|γ_1-(2m)/n|+...+|γ_n-(2m)/n| where γ_1,...,γ_n are the ei...

the present study was an attempt to compare the effect of three vlss, namely word-part strategy, word-card strategy and context-clue strategy on immediate and delayed english vocabulary retention of iranian third grade high school students. to this end, 90 students, studying at three high schools in tabriz, in three intact groups, were considered as the participants of the study. in order to en...

Last month, The spider's web looked at the range of biological resources available on the net. This month there are more specific tips on how to get the most out of these tools, for the least effort, with an emphasis on tools for sequence analysis. As is true of almost any use of computers, getting something done on the net requires a lot of non-intuitive knowledge, and net knowledge becomes re...

As IP technologies providing both tremendous capacity and the ability to establish dynamic secure associations between endpoints emerge, Virtual Private Networks (VPNs) are going through dramatic growth. The number of endpoints per VPN is growing and the communication pattern between endpoints is becoming increasingly hard to forecast. Consequently , users are demanding dependable, dynamic con-...

abstract the word science has gone through semantic change in different historical periods and in relation to the cultural and social circumstances of the time and thus has been used in various senses. a semantic study of word in the pre- and post-islamic eras will reveal that the word has been used in different and even opposite senses. this means that, in the age of ignorance (pre-islamic era...

this study strives to investigate the importance of ‘education’ and ‘gender’, as two major sociolinguistic variables, in accepting or rejecting the words coined by the iranian academy of persian language and literature (apll). a total of 500 students from state universities in tehran were chosen as subjects and provided with a questionnaire consisting of 50 apll equivalents. the respondents’ ac...

We propose a novel automatic target recognition (ATR) system for classification of three types of ground vehicles in the MSTAR public release database. First, each image chip is pre-processed by extracting fine and raw feature sets, where raw features compensate for the target pose estimation error that corrupts fine image features. Then, the chips are classified by using the adaptive boosting ...
