HAVANA Cheap Ecco Sandals Mens Ireland , June 1 (Xinhua) -- Cuban Eugenio George, chosen by the International Volleyball Federation (FIVB) as the best coach in the 20th century, died at 81 in Havana due to a "long and painful illness", local media reported on Sunday.

Local radio station Radio Reloj said that George died on Saturday night and his body was to be mourned in a funeral home in Havana so people will pay tribute.

George led the Cuban women's team to three Olympic gold medals in Barcelona 1992, Atlanta 1996 and Sidney 2000.

He also led the team to win the world championships in Leningrad 1978, Brazil 1994 and Japan 1998.

SAN FRANCISCO Cheap Ecco Sandals Ireland , July 19 (Xinhua) -- Two researchers at Oregon State University have built a framework for autonomous underwater vehicles, or AUVs, to plan energy-efficient trajectories through disturbances that are strong and uncertain, like ocean currents and wind fields.

AUVs such as underwater gliders are valuable research tools limited primarily by their energy budget, meaning every bit of battery power wasted via inefficient trajectories cuts into the time they can spend working. And greater energy efficiency means the AUVs can gather data longer and better.

"Historically, a lot of oceanography data sets and sampling came from using ships Cheap Ecco Boots Ireland , which are expensive and can only really be out for a few days at a time," noted Dylan Jones, a Ph.D. student in OSU's robotics program and lead author on the study published in IEEE Robotics and Automation Letters. "With autonomous underwater vehicles, you can get months-long monitoring. And a way to extend those vehicles' missions is through smarter planning for how they get from one point of interest to another."

Built by Jones and Ph.D. advisor Geoff Hollinger, assistant professor of mechanical engineering in OSU's College of Engineering, the framework involves an algorithm that samples alternate paths , and comparison metrics that let a vehicle decide when it makes sense to switch paths based on new information collected about environmental disturbances.

They tested the framework in a simulated environment, namely a data set of currents from the Regional Ocean Modeling System, and also on a windy lake with an autonomous boat. The results show that the algorithm can plan vehicle paths that are more energy efficient than ones planned by existing methods, that it is robust enough to deal with environments for which not much data is available, and that three of the framework's five path comparison metrics can be used to plan more efficient routes compared to planning based solely on the ocean current forecast.

"These are under-actuated vehicles - they don't go fast in relation to the strong ocean currents, so one way to get them to travel more efficiently is to go with the flow Cheap Ecco Shoes Ireland Clearance , to coast and not use energy," Jones said, noting that overcoming strong disturbances is a critical component of putting any kind of robot in a real-life environment, and past planning algorithms haven't always considered the dynamics of the vehicle they were planning for.

"We're building more intelligence into these vehicles so they can more reliably accomplish their missions," he was quoted as saying in a news release from OSU in the U.S. Pacific Northwest on Wednesday.

Future research will also deal with "informative path planning," namely gathering information about the environment and disturbances that the algorithm can use later to plan energy-efficient routes. "How do we combine these two ideas - planning a path for energy efficiency while also trying to gather information that will inform efficient path planning?" Jones said. "There will be tradeoffs and it might come down to Cheap Ecco Shoes Ireland Online , do I pay five hours now to save six hours later on?"

PARIS, March 10 (Xinhua) -- China became the world's leading exporters of cultural goods in 2013, outpacing the United States Cheap Ecco Shoes Ireland Sale , a UNESCO report showed on Thursday.

A new report by the UNESCO Institute for Statistics (UIS) pointed out that the total value of China's cultural exports stood at 60.1 billion U.S. dollars, more than double that of the United States' 27.9 billion dollars.

"Trade in cultural goods totaled 212.8 billion U.S. dollars in 2013, nearly double the amount in 2004. This is further evidence of the critical role cultural industries play in today's global economy," said Silvia Montoya, director of the UIS.

With advanced countries were still dominating imports of cultural goods, emerging markets bolstered their exports of cultural products with Turkey and India strengthened their position in recent years Cheap Ecco Shoes Ireland , joining the world's top 10 exporters of such goods.

Art and crafts were among the 10 most traded cultural goods. Statues, statuettes and paintings also gained ground with their share of the trade in art and crafts was worth 19 billion dollars in 2013, the report showed.

As to gold jewelry, widely considered as "safe harbor in uncertain times," its sales totaled 100 billion dollars over the period.

However, trade in movies shrunk by 88 percent from 2004 to 2013 and traded musical goods also suffered a setback over the period. Meanwhile Cheap Men's ECCO Cool 2.0 Leather GTX DARK SHADOW Ireland , audio-visual services as a whole steadily gained ground, the report said.
