his paper discusses how to provide reliable broadcast communication for multiple entities in d s distributed systems by using unreliable broadcast communication services. In real distribute ystems, each process in some application group rather sends every message to only the subt f set than all the processes in the group, and each process receives only messages destined to i rom some process in...

Broadcast is an important application in wireless networks, e.g. for video streaming, file distribution, or event notification. Wireless nodes are battery powered, their network lifetime depends on the energy consumption. Thus, energy efficiency is an important metric when designing broadcast protocols in infrastructureless and all-wireless networks. In this paper, we apply game theory to solve...

Broadcast encryption is an interesting application of cryptography which allows one to broadcast a secret to a changing group of intended recipients in such a way that no one outside this group can view the secret. Interest in using broadcast encryption techniques has grown considerably in recent years and such techniques have been integrated in many applications and technologies such as virtua...

Information on weed distribution within the field is necessary to implement spatially variable herbicide application. Since hand labor is costly, an automated weed control system could be feasible. This paper deals with the development of an algorithm for real time specific weed recognition system based on Histogram Maxima with threshold of an image that is used for the weed classification. Thi...

Available research is reviewed on the interactions of application variables, herbicides, and species. Objectives of this review are to gain insights into why variation occurs with herbicide performance, how current knowledge might be applied to enhance efficacy and consistency, and research pathways that should foster integration of applicationefikacy models. A historical context is provided on...

in order to study the tolerance level of different wild barley (hordeum spontaneum) populations to clodinafop propargyl (topic®), a pot dose response experiment was conducted in a completely randomized design with three replications at ferdowsi university of mashhad greenhouse in 2009. cultivared barley (hordeum vulgare) and three wild barley populations (shiraz, boshroyeh, and torogh) were stu...
