in many autonomous mobile applications, robots must be capable of analyzing motion of moving objects in their environment. duringmovement of robot the quality of images is affected by quakes of camera which cause high errors in image processing outputs. in thispaper, we propose a novel method to effectively overcome this problem using neural networks and kalman filtering theory. thistechnique u...

People join peer-to-peer networks for economic and social reasons. From an economic perspective, people join peer-to-peer (P2P) networks based on the size of the networks. However, from a sociological perspective, when people adopt technologies, they create an alternative social network motivated by extrinsic and intrinsic rewards. In this study, we develop a conceptual framework for measuring ...

METHODS Data were drawn from a representative sample of adults aged 18 and older in Greater Beirut, Lebanon (N = 500). Multiple linear regression and multilevel models were conducted to examine main a...

Infants and adults learn new phonological varieties better when exposed to multiple rather than a single speaker. This article tests whether having a larger social network similarly facilitates phonological performance. Experiment 1 shows that people with larger social networks are better at vowel perception in noise, indicating that the benefit of laboratory exposure to multiple speakers exten...

The increasing ubiquity of web-based social networking services is a striking feature of modern human society. The degree to which individuals participate in these networks varies substantially for reasons that are unclear. Here, we show a biological basis for such variability by demonstrating that quantitative variation in the number of friends an individual declares on a web-based social netw...

abstract- the high production of orange fruit in iran calls for quality sorting of this product as a requirement for entering global markets. this study was devoted to the development of an automatic fruit sorter based on size. the hardware consisted of two units. an image acquisition apparatus equipped with a camera, a robotic arm and controller circuits. the second unit consisted of a robotic...

Networks and the relationships embedded in them are critical determinants of how people communicate, form beliefs, and behave. E-commerce platforms such as Amazon and eBay have made actions of “strangers” more observable to others. More recently, social media websites such as Facebook and Google Plus have created networks of “friends”, and the actions of these friends have become more visible t...

prefrontal cortex correlate with the size of social group in which individuals were housed. Remarkably, they were also able to demonstrate that, within social groups, there were correlations between the volumes of these same regions and the dominance ranks of individual monkeys. The Sallet et al. results are important for two reasons. First, they confirm that the findings reported for humans ap...
