an efficient cluster head selection algorithm in wireless sensor networks is proposed in this paper. the implementation of the proposed algorithm can improve energy which allows the structured representation of a network topology. according to the residual energy, number of the neighbors, and the centrality of each node, the algorithm uses fuzzy inference systems to select cluster head. the alg...

the autotetraploidy was achieved in basil using tip meristem treatment of seedlings with various concentrations of colchicine solution (0, 0.05, 0.1, 0.2, 0.5 and 0.75% (w/v) ph = 6). a significant increase in the essential oil content was observed in tetraploids as they carry the potential of productivity of 69 % more oil over the diploids. a field experiment was conducted to investigate the e...

We present a semi-supervised clustering approach to induce script structure from crowdsourced descriptions of event sequences by grouping event descriptions into paraphrase sets (representing event types) and inducing their temporal order. Our model exploits semantic and positional similarity and allows for flexible event order, thus overcoming the rigidity of previous approaches. We incorporat...
