A documenZ can be divided inio zones on the basia of ils content. For ezample, a zone can be either tezt or non-tezt. This paper describes an algorithm to classify each given document zone into one of nine diflerent classes. Features for each zone such as run length mean and variance, spatial mean and variance, fraction of the total number of black pizels in the zone, and the zone width ratio f...
wireless sensor networks (wsns) are one of the most interesting consequences of innovations in different areas of technology including wireless and mobile communications, networking, and sensor design. these networks are considered as a class of wireless networks which are constructed by a set of sensors. a large number of applications have been proposed for wsns. besides having numerous applic...
Evaluation of the Effect of Four Herbal Extracts on Growth of Streptococcus mutans and Lactobacillus
Background and aim: Reduction of oral pathogens is very important in the healing of oral ulcers and infections. The side effects of chemical drugs have attracted more attention to medicinal plants. The present study assessed the effect of clove, thyme, garlic, and cinnamon ethanolic extracts on the growth of Streptococcus mutans (S. mutans) and Lactobacillus by measuring the inhibition zone dia...
In this paper Semi-Markov models are used to forecast the triple dimensions of next earthquake occurrences. Each earthquake can be investigated in three dimensions including temporal, spatial and magnitude. Semi-Markov models can be used for earthquake forecasting in each arbitrary area and each area can be divided into several zones. In Semi-Markov models each zone can be considered as a sta...
This paper presents an overview of Feature Extraction techniques for off-line recognition of isolated Gurumukhi numerals/characters. Selection of Feature Extraction method is probably the single most important factor in achieving high performance in pattern recognition. Our paper presents Zone based hybrid approach which is the combination of image centroid zone and zone centroid zone of numera...
One of the applications of P460NH micro-alloy steel is its use in pressure vessel tanks. Electrode E8018-G can be used for welding this steel. In this study, to obtain the optimal welding parameters, the arc process based on ASME IX standard was used. Then, by sampling from the weld section, Vickers hardness test was performed and hardness profiles were drawn in different areas. Then the micro...

1.0 overview it seems that grammar plays a crucial role in the area of second and foreign language learning and widely has been acknowledged in grammar research. in other words, teaching grammar is an issue which has attracted much attention to itself, and a lot of teachers argue about the existence of grammar in language teaching and learning. this issue will remind us a famous sentence f...
introduction one of the most vulnerable water resources against contamination is ground water table. these resources are exposed to contamination in various forms. identifying and controlling contamination in these resources are more difficult and costly than surface waters. also because of the persistence of contamination in these resources, the best way to prevent their contamination is to id...
