A mid-course correction (MCC) policy has been shown as a practical approach to compensate the effects of the new disturbances on the final particle size distribution (PSD) in the emulsion polymerization process. However, the development of control model remains immature in the practical sense. In this paper, a control strategy to control the bi-modal particle size distribution in an emulsion co...

Online reviews play a crucial role in helping consumers evaluate and compare products and services. This critical importance of reviews also incentivizes fraudsters (or spammers) to write fake or spam reviews to secretly promote or demote some target products and services. Existing approaches to detecting spam reviews and reviewers employed review contents, reviewer behaviors, star rating patte...

In order to facilitate and improve collaboration among co-authors, working in the Web environment, documents must be made seamlessly available to them. Web documents may contain multimedia resources, whose management raises important issues due to the constraints and limits imposed by Web technology. This paper proposes an adaptive support for distributing shared Web documents and multimedia re...

co-training can learn from datasets having a small number of labelled examples and a large number of unlabelled ones. It is an iterative algorithm where examples labelled in previous iterations are used to improve the classification of examples from the unlabelled set. However, as the number of initial labelled examples is often small we do not have reliable estimates regarding the underlying p...

the contamination of riverbed sediments by heavy metals has assumedserious problems due to their toxicity and accumulative behavior. the present studyinvestigated the concentrations of heavy metals from the bottom sediments of shitalakhyariver to understand the level of contamination and their distribution. the averageconcentrations of heavy metals al, k, ca, mg, fe, as, cu, co, cr, and zn are ...

We study the influence of economic inequality on co-operation and aid distribution in community-based development schemes. For this, we organized a field experiment in which community members contributed to a collective effort to attract aid. We find that devolving aid distribution to community representatives increases the aid attracted, but that this benefits community representatives only. A...

We present an analysis of the excitation conditions of the molecular gas in the streamers and the outflow of M 82 based on observations obtained at the IRAM 30 m telescope. Our analysis of J=1→0 and J=2→1 transitions of CO and 13 CO and the CO(J=3→2) line in 13 regions outside the central starburst disk shows that the gas density within the streamer/outflow system is about an order of magnitude...

This analytical electron microscopy study was performed to understand better the microstructure of CoCrPt:SiO2 media. The topology of the magnetic Co alloy grains and the distribution of the elements in the thin films were of special interest. High angle annular dark field images revealed that many grains in the range 5–8 nm have a cavity in their center, observed by low mass-thickness contrast...
