Autom.ted im.ge system. to characterize aquatic organism. im.rove research and enable fast response to environm.ntal risk situations. In Novem.er 2015, a dam.in m.riana City-m. (Brazil) collapsed and led to the disposal of m.d tailings from.the m.ning process to the Doce River. The accident resulted in several casualties and incalculable dam.ge to surrounding com.unities and the environm.nt. The m.d increased water turbidity, an essential condition to the functioning of the im.ge analysis system., and directly affected the characterization of the organism., m.king it im.ossible to distinguish copepods in the m.d, due to the blurred outline. To get a quick response evaluating environm.ntal situations, this work aim.d to develop and test different algorithm. characterizing and classifying copepods by their size (length and area) using in situ im.ges acquired by the Lightfram. On-Sight Keyspecies Investigation device. Field tests were carried out under different turbidity levels throughout the gradient observed in the coastal zone adjacent to the Doce River. The best algorithm.reduced nearly 50% of the noise in som. im.ges when com.ared with m.nual treatm.nt and led to 96% accuracy in m.asurem.nt and counting. Sem.-autom.ted devices that perform.post-processing corrections are suitable for fast environm.ntal evaluation under high turbidity scenarios.

Hydrodynam.cs of the interceptor on a 2-D flat plate by CFD and experim.nts

引用

Journal of Hydrodynam.cs 2015年第6期27卷 919-933页

作者： m.NSOORI m. fernandes A.C. Departm.nt of Naval and Ocean Engineering Federal University of Rio de Janeiro

Nowadays, the use of interceptor by both partial and total dynam.c lift crafts is quite com.on. In this article, a lot of evidence is given regarding the effectiveness of interceptor. The interceptor, when placed at the stern region, changes the pressure distribution around the craft. Its presence affects drag force, lifting force and the position of pressure＇s center leading to a new trim. This study focuses on hydrodynam.c effects of interceptors on a 2-D fiat plate based on both com.utational fluid dynam.c （CFD） and experim.ntal approaches. The Reynolds average Navier-Stokes （RANS） equations are used to m.del the flow around a fixed flat plate with an interceptor at different heights and attack angles. Based on finite volum. m.thod and SIm.LE algorithm.which uses static structures, this m.del can be analyzed and the RANS results can be com.ared with the experim.ntal data obtained in the current channel of the laboratory of waves and current of COPPE/UFRJ （LOC in Portuguese acronym.. According to the results, the increase of pressure at the end of the flat plate was proportional to the interceptor height. In addition, the existence of interceptors can significantly increase the lift force coefficient at high angles of attack also proportional to the interceptor height. The presence of interceptor at the end of the fiat plate increased both the lift coefficient and the drag coefficient but hydrodynam.c drag did not grow as fast as the lift coefficient did. The lift coefficient increased m.ch m.re. Furtherm.re, the results showed that the interceptor effectiveness is proportional to the boundary layer thickness at the end of the fiat plate. As the interceptor was inside the boundary layer alterations of flow speed led to changes in boundary layer thickness, directly affecting interceptor＇s efficiency. Optim.m.choice of interceptor height had a great effect on its efficiency, and in choosing it the flow speed and length of the boat m.st be taken into consideration.

Effect of Noisy Fitness in Real-Tim. Strategy Gam.s Player Behaviour Optim.sation Using Evolutionary Algorithm.

Journal of Com.uter Science & Technology 2012年第5期27卷 1007-1023页

This paper investigates the perform.nce and the results of an evolutionary algorithm.（EA） specifically designed for evolving the decision engine of a program.（which, in this context, is called bot） that plays Planet Wars. This gam., which was chosen for the Google Artificial Intelligence Challenge in 2010, requires the bot to deal with m.ltiple target planets, while achieving a certain degree of adaptability in order to defeat different opponents in different scenarios. The decision engine of the bot is initially based on a set of rules that have been defined after an em.irical study, and a genetic algorithm.（GA） is used for tuning the set of constants, weights and probabilities that those rules include, and therefore, the general behaviour of the bot. Then, the bot is supplied with the evolved decision engine and the results obtained when com.eting with other bots （a bot offered by Google as a sparring partner, and a scripted bot with a pre-established behaviour） are thoroughly analysed. The evaluation of the candidate solutions is based on the result of non-determ.nistic battles （and environm.ntal interactions） against other bots, whose outcom. depends on random.draws as well as on the opponents＇ actions. Therefore, the proposed GA is dealing with a noisy fitness function. After analysing the effects of the noisy fitness, we conclude that tackling random.ess via repeated com.ats and reevaluations reduces this effect and m.kes the GA a highly valuable approach for solving this problem.

To the Editor： Xie et al, analyzed warfarin doses in pulm.nary em.olism.（PE） and its adverse effects in patients with obstructive sleep apnea hypopnea syndrom. （OSAHS）. The key findings were that OSAHS patients required a significantly higher dose of warfarin than their non-OSAHS counterparts （4.73 m. vs. 3.61 m., P 〈 0.001） and that PE recurrence was higher in OSAHS than in non-OSAHS groups after withdrawal ofwarfarin （21.43% vs. 6.78%, P = 0.047）.
