in order to evaluate the interference effect natural population weeds and plant density, an experiment with randomized complete block design in factorial arrangement with 4 replications was conducted in 2006 in a field experiment at ramin agricultural and natural resources university, khouzestan. treatments included two factor, plant density of corn at three levels (4, 7 and 10 plants m-2) and ...

The throughput of a wireless network is often limited by interference caused by multiple concurrently active nodes. The conventional approach of using a “one-transmission-ata-time” MAC protocol to combat interference leads to a significant loss of achievable throughput compared to schemes such as interference cancellation that keep all transmitters active simultaneously. Unfortunately, interfer...

The concept of ad-hoc networks has first arisen in 1970s. Adhoc networks act differently than other wireless networks, for each node can act as a router. For that ad-hoc networks can be used in some interesting applications. However, if the network wasn’t well constructed, it would have an inefficient performance. Interference can be considered to be one of the worst problems, the network can s...

a field experiment was conducted in research farm of isfahan university of technology, isfahan, iran in 2011 . various weeding periods were investigated on growth and yield of potato under drip tape and furrow irrigation systems. a split plot arrangement was used in a randomized complete block design with three replications. irrigation treatments were included in main plots and periods of weed ...
