Earth Hour Calls Attention to Climate Change
In 2007, the first Earth Hour occurred in Sydney, Australia with 2.2 million people turning off their lights in a show of support for efforts to fight climate change. Pittsburgh began participating the following year and in 2010, 128 countries took part in Earth Hour. That included 90 million Americans and iconic American landmarks, such as, Seattle’s Space Needle, the Las Vegas Strip, St Louis’ Gateway Arch, and the Brooklyn Bridge.
This evening Carlow, Carnegie Mellon, Chatham, Duquesne, Point Park and the University of Pittsburgh will all have buildings go dark for one hour.
Since 2008, Councilman William Peduto has led the effort to have Pittsburgh be a partner in this global event.
“I am proud of Pittsburgh’s continued environmental leadership. Pittsburgh’s universities have long been leaders of the region and it is only appropriate that they lead Pittsburgh’s Earth Hour efforts.”

"Watson" Goes for Win
The language-computing computer Watson will attempt to hold on to its lead tonight in the final episode of a three-part Jeopardy! series pitting the computer versus two of the shows greatest champions, Ken Jennings and Brad Rutter.
Carnegie Mellon University professor Eric Nyberg is a contributor in the creation of Watson, and says he will watch with excitement, though he already knows the result.
Nyberg along with CMU students Nico Schlaefer and Hideki Shima work with IBM on the development of the computer which has earnings of $35,734 after 2 rounds of Jeopardy compared to $10,400 for Rutter and $4,800 for Jennings. The 3 episodes were filmed last month, so Nyberg and other contributors to the computer’s creation know the results. Nyberg was surprised by Watson’s success on the second day.
“I think my expectation was really that it would be like what you saw on day one where it was sort of a neck and neck kind of thing where Watson did very well in some categories and didn’t really answer anything in some of the other categories,” Nyberg says. “That’s actually quite characteristic of Watson’s performance overall.”
The language computing computer processes the clues using a vast knowledge of the English language, programmed by people like Nyberg. Watson then calculates a confidence level for the answers it’s considering and buzzes in if it seems sure.
Nyberg says the research has been great for the field of language computing technology and he says CMU has already implemented improvements to the model idea.
“One of the things we’re working on at Carnegie Mellon is a technique that basically helps Watson to study for a particular topic,” Nyberg says. “You can give Watson documents that are on topics that you want him to learn about and then we have another tech that will go out and find other relevant texts that are available.”
However if Nyberg wants viewers to know anything, he jokes that Watson’s intelligence is nothing to fear.
“It’s not going to take over the world, it’s not dangerous and nobody’s going to give any launch codes to Watson when it thinks that grasshoppers eat kosher and Toronto is a U.S. city.”

Pittsburgh Moves Forward in Entertainment Tech Field
PET’s goal is to bring together all of the region’s entertainment technology companies under one banner.
“We’re going to hope to get all of the entertainment companies together, and all of the people interested in entertainment technology, film, and all the innovative things we’re trying to do together, in one room,” Organizer Kim Chestney Harvey said of the launch, which will be hosted at the Entertainment Technology Center by Don Marinelli.
Chestney Harvey says along with bringing all these people together as part of one group, creating a database for filmmakers who come to the region is another objective of the PET.
“We will put the contents of this database into a nationwide directory for the filmmakers to use and access,” Chestney Harvey says. “When they come here regionally to work they can look and see what assets they have here to choose from.”
The PET is a project put together by four groups including the Pittsburgh Technology Council, the Idea Foundry, the Pittsburgh Film Office, and Carnegie Mellon’s Entertainment Technology Center. Some of the technologies that the region’s companies have produced for filmmakers include music compostion, 3-D computer graphics and visual effects, and branded gaming among other things.
“We realize that we have a really robust culture and a lot of really interesting things happening here and we kind of wanted to show our support for that and come up with some way to support what all of our local companies are doing,” Chestney Harvey says.

Scientists Gather at CMU to Talk about Gigapixels
The technology has its roots in NASA labs when space exploration vehicles took hundreds of photos that were merged into massive panoramas. The technology has gained some fame recently with CMU’s GigaPan project. Nourbakhsh says the use of multiple high resolution images is starting to show up in a wide rang of disciplines. He says it is in use at the microscopic level where individual insects are being photographed hundreds of times, at the human scale with projects such as scans of fields of flowers where individual bees can be found doing their work, to the intergalactic scale being tackled by NASA scientists. Nourbakhsh says scientists are even using GigPan type technologies in time-lapse projects. “It lets the public visually understand science in ways that were not possible before and that means the public is better able to understand the future of the world and the way the public impacts the world,” says Nourbakhsh.
Nourbakhsh says he is excited by the fact that the event has drawn scientists from such a broad range of fields. Vertebrate paleontologists, for instance, will report at the conference on their use of gigapixel imaging to provide detailed documentation not only of the quarries where fossils were discovered but also of the fossils themselves. Entomologists will discuss how they used GigaPan to watch 3,200 cells in a beehive breeding frame over a period of 12 days as they searched for clues to Colony Collapse Disorder. “We’re still early in the evolution of this technology, but we hope that this conference will help us identify those areas where gigapixel imaging holds the most potential, whether as a research tool, an educational device or as a means of engaging the public at large,” says CMU scientist Randy Sargent.
Along with the scientific program, the conference will feature a juried gallery show at Carnegie Museum of Natural History in which eight images will be exhibited as prints measuring 4 feet high and up to 23 feet wide. The gallery prints will remain on display through the end of the year.

TechBridgeWorld Provides Technology to Underprivileged People
After growing up in Sri Lanka at the base of the economic pyramid and seeing how the lack of modern technologies can damage a society, Dias has not stopped trying to change things.
Dias has seen the organization founded in 2004 grow from one person to many student and volunteer researchers with the goal of providing modern technologies to those nations without any.
"Our primary goal is to innovate computing solutions or create new computing solutions that address the needs and are relevant to people in underprivileged communities,” Dias explains.
Dias provided an example of one of TechBridgeWorld’s most successful works that is still being used to teach today. In 2006, TechBridgeWorld began working with a blind school in India to create a program that helps students read and write Braille and offers the functions of correction and audio feedback. The tutor has since been expanded to blind schools in the United States, China, Bangladesh, and others.
The organization has focused on small projects since it’s inception but hopes to have the opportunity to work on large-scale projects with bigger communities.
"We’ve sort of focused on smaller scale projects, how do we scale this up given the knowledge that we have?” Dias asks.
Dias earned her undergraduate degree in computer science and physics from Hamilton College and then began a graduate study at Carnegie Mellon University. With a Ph.D. in robotics in hand, Dias applied for a research faculty position at CMU and began the organization TechBridgeWorld in 2004.
The organization receives funding from multiple sources including individual donations, financial grants, and corporate donations from sponsors like Google and Yahoo, but Dias knows funding is essential to the growth of the team and it’s ability to help communities.
“Additional funding will take TechBridgeWorld to an entirely different level,” Dias says. “We would be able to impact so many more students and communities around the world.”

Sky Art Floats Above Pittsburgh
A small airplane will use white smoke to write common advertising phrases like “SPACE AVAILABLE,” “ALL SALES FINAL,” and “EVERYTHING MUST GO” in the city sky as part of Carnegie Mellon University Professor of Art Kim Beck’s “The Sky is the Limit” project.
The block letters will be written one mile high, and Beck says people should be able to see them all across the city at 6 o’clock tonight and 10 a.m. Saturday.
Beck says she expects a variety of reactions.
“I think some people will be utterly confused by it. I think some people will think it’s actually advertising something but then not know what the advertisement’s for, and then I think some people will make the leap and have an environmentalist read on it. Maybe somebody will read ‘Everything Must Go’ and it’ll have kind of a personal resonance.”
After the ‘performance’ is finished, Beck will install large pictures of the skywriting in storefronts downtown. Beck says while the skywriting will fade in an hour or less, the pictures will be a permanent reminder of the impermanent – another theme she calls central to the work.
Beck says she got the idea to depict advertising phrases from the overabundance of them during the recent economic recession. She says while they often mean “good deals” on the consumer’s end, they also mean a lost job or a company closing at the seller’s end.

Green Building Process Scrutinized
Led by Pitt engineering professors Melissa Bilec and Amy Landis, the study aims to make sure green buildings are performing as well as they can.
Bilec says every new structure, including any green building, has an environmental footprint from the materials used to build it to the last day of its existence. That total environmental effect constitutes a building’s life-cycle assessment, or LCA.
Bilec says one of the goals is to expand the scope of LCAs to include the building’s effect on the people who live or work in it.
“[We’re] really trying to connect people with their buildings. Right now, 90% of our time is spent inside, but we really know very little about the environment that we occupy, from the air quality to the energy usage or the water usage. So that’s what we’re trying to do, is connect people with the indoor environment.”
Another component of the study is a survey of architects, contractors, and other people in the construction process to determine the weaknesses of the LCA.
Bilec says the team will ultimately submit new recommendations to the United States Green Building Council.

Take Part In Pittsburgh's Giant Panorama
Pittsburghers are invited to make signs, wear costumes and pose for the camera as it takes a massive high-resolution picture of our city. The picture will be accessible online before the end of October.
Carnegie Mellon's STUDIO for Creative Inquiry will broadcast updates every five minutes using Twitter and Facebook to help participants know where the GigaPan camera is pointing at the time they check.
Carnegie Mellon's David Bear began the project during a fellowship at CMU and has been financially supported by the Sprout Fund and the Heinz Endowments. The GigaPan Camera, and other tools used for todays project, were developed by the Create Lab at CMU's Robotics institute.

Open Contest Seeks Best Use of Elec. Car Batteries
The college’s electric car program, ChargeCar, announced its “ChargeCarPrize” contest last week. The person who comes up with the best system for distributing energy from electric car batteries wins an electric car.
Assistant Professor of Robotics Illah Nourbaksh says eight “secret drivers” will have driving habits like distance and altitude recorded by a GPS system.
“Every month, the data that has been accumulated for the past month of driving gets tested against the best open algorithms that have been submitted to us so far on the website. And so we see for the past month, if any of these drivers were driving an electric car and they were using the algorithms that have been submitted, how efficient would they have been? How little energy would they have been able to use and still get a great commute done?”
Nourbaksh says combined with new supercapicitor technology developed by CMU, the best algorithm will allow electric car batteries to shrink. Since batteries are the most expensive part of the cars, that means prices will shrink as well.
“When they’re $45,000, they’re just something for the elite. If we can get that cost down so a new electric car is fifteen- or twenty-thousand dollars, then we’re talking about a much bigger demographic.”
Nourbaksh says the contest is slated to take up to 18 months, but it could finish early if “some genius” comes up with a great algorithm sooner than that. In the meantime, the algorithm that performs the best by the end of each month earns its author a $250 gift card.
Details on ChargeCarPrize can be found at ChargeCar's website.

Shale Gas Regulations and Technology Discussed
Engineers are always racing to fill voids. In the case of Marcellus Shale gas drilling, they have spent a great deal of time looking for ways to lower the cost of cleaning water coming out of the wells after the hydrologic fracturing process to the standards set by state and federal regulators. Kelvin Gregory is an engineering professor at CMU and moderated the panel. He says one solution is finding ways to reuse the water that comes back out of the well to fracture another well. Typically 30%-40% of the water pumped underground comes back out of the well. When it does so, it is contaminated with salts known as total dissolved solids. Gregory says there are also ways to choose the source of the water wisely to lower the environmental impact. Water that flows out of abandon mines often fouls creeks and streams for miles. He says that water can be used in the fracturing process. Gregory says that will help clean up the impacted waterways and reduce the amount of clean water pulled from other water sources.
Gregory says it is not a question of “if” the salts can be removed but rather a question of “at what cost.” He says the process is very energy intensive but if engineers can find ways to reduce the cost it allows gas companies to operate profitably with tighter environmental regulations in place. Gregory believes that to make the regulatory and entrepreneurial process mesh, all sides need to be as transparent in the effort as possible and the public needs to be informed of all the issues at hand.
