In nowadays network community, (P2P) networks are flourishing as a fine can didate for resource sharing over internet. In unstructured network, overlay is constructed freely without any strict constraints on top of the internet infrastructure leads to major confront in P2P searching with efficient resource discovery. In the existing unstructured Peer-to-Peer (P2P) searching scheme supporls the file name or keyword based limited search techniques. Therefore, efficient search is a challenging task in unstructured networks. Mainly, the major basic issues in P2P networks are i) how to locate the peers efficiently to provide response for requested query. The novel decentralized P2P construction algorithm is proposed to enhance the searching process in unstructured overlay P2P networks. The main aspect is to restructure and optimize the unstructured p2p overlay based on properties such as high clustering among similar peers, low diameter among the distinct peers to rapidly propagate the query message between them and overlay links must be very progressive. This approach constructs the optimized overlay in a decentralized manner by exploiting the similarity ofparlicipating peers. Therefore, it does not need centralized servers to perform query searching therefore it can reach the destination peer by progressively and effectively exploiting peer similarity on search path. This approach exhibits file sharing pattern based on property ofpower-Iaw that leads to achieve precise performance guarantees in terms of the less routing hop count an d th e flourishing qu ery ratio.Index Termspeer-to-peer systems, semantic overlay networks, search -informational retrieval.
Pesticides are widely used in agriculture for the management of pests (weeds, insects or pathogens). They are generally applied as a spray to cover the target (e.g. an insect, leaf surfaces or part of a plant) with pesticide-laden droplets. Spray may, however, be lost to non- target areas within a crop through deposition on to the soil or on non-target plant surfaces. The plant architecture of the crop and weed species can influence the distribution of the spray droplets. The action of wind may also result in spray moving away from the spray area. By selecting and using spray equipment and techniques that maximise deposition of pesticides onto the target, it is possible to both maximise the effectiveness of the pesticide application and reduce the amount of off-target deposition and damage. Hence, it is necessary to measure the distribution of spray deposits in the leaves of different crop canopies in relation to droplet size, droplet trajectory, spray application volume and canopy structure. A study on the deposition of spray chemicals on cotton crop was conducted using three methods namely i) Gravimetry method ii) Leaf Area Index and iii) QuEChERS (Quick, Easy, Cheap, Effective, Rugged and Safe) method and the efficiency of the methods on the requirement of effective volume of spray chemicals for unit cropped area was determined.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
