Innovative underwater camera could transform future submarines’ sensors | Defense Update:
"Virtual
periscope" sees above-surface/airborne objects from underwater -
American Society for Technion-Israel Institute of Technology
“Stella Maris is a novel approach to a virtual periscope as it passively
measures water and waves by imaging the refracted sun.” Schechner
added, “When the water surface is wavy, sun-rays refract according to
the waves and project onto the solar image plane,” he explains. “With
the pinhole array, we obtain an array of tiny solar images on the
diffuser.” When all of the components work together, the Stella Maris
system acts as both a wave sensor to estimate the water surface, and a
viewing system to see the above surface image of interest through a
computerized, “reconstructed” surface. A proof of concept system
demonstrating the new method has already been tested in several lab and
field experiments. Another innovation introduced by Schechner Hybrid Imaging
Lab exploited natural “underwater flicker,” (rapid, random change of
underwater lighting, caused by the water surface wave motion) to create a
three-dimensional mapping of the sea floor.

Ethics for Self Guided Autos
The Mathematics of Murder: Should a Robot Sacrifice Your Life to Save Two? | Popular Science
In the absence of a universal standard for built-in, pre-collision ethics, superhuman cars could start to resemble supervillains, aiming for the elderly driver rather than the younger investment banker—the latter's family could potentially sue for considerably more lost wages. Or, less ghoulishly, the vehicle's designers could pick targets based solely on make and model of car. “Don’t steer towards the Lexus," says Cahill. “If you have to hit something, you could program it hit a cheaper car, since the driver is more likely to have less money.”
The greater good scenario is looking better and better. In fact, I’d argue that from a legal, moral, and ethical standpoint, it’s the only viable option. It’s terrifying to think that your robot chauffeur might not have your back, and that it would, without a moment’s hesitation, choose to launch you off that cliff. Or weirder still, concoct a plan among its fellow, networked bots, swerving your car into the path of a speeding truck, to deflect it away from a school bus. But if the robots develop that degree of power over life and death, shouldn’t they have to wield it responsibly?
“That’s one way to look at it, that the beauty of robots is that they don’t have relationships to anybody. They can make decisions that are better for everyone,” says Cahill. “But if you lived in that world, where robots made all the decisions, you might think it’s a dystopia."
Russians to exercise with Chinese in South China Sea
Pacific Fleet Warships Head to Shanghai for Russia-China Drills | Defense | RIA Novosti
VLADIVOSTOK, May 14 (RIA Novosti) – A Russian Pacific Fleet squadron, led by the guided-missile cruiser Varyag, sailed from Vladivostok on Wednesday to participate in the Russia-China exercises Naval Interaction-2014, a military spokesman told RIA Novosti.
The squadron, which also includes the large anti-submarine ship Admiral Panteleyev, the large amphibious ship Admiral Nevelskoy, the destroyer Bystry, the tanker Ilim and the sea-going tugboat Kalar, is heading to Shanghai, said Capt. 1st Rank Roman Martov.
“Upon arrival, sailors will take part in the joint Russia-China exercises in the South China Sea,” he said.

Kirwan to step down as university system chancellor
William E. Kirwan, Chancellor, University System of Maryland
Kirwan to step down as university system chancellor - baltimoresun.com
William E. Kirwan, who as chancellor of the University System of Maryland over the past dozen years helped oversee the rise of several of the state's public universities to national prominence, will step down from his position as soon as a successor is found, he said Tuesday.
Kirwan, 76, a gregarious leader who maintained good relations with state officials, university presidents, members of the Board of Regents, faculty, business leaders and students, said he hopes to remain active in higher education with work on expanding access for low-income students.
A former president of the University of Maryland, College Park, Kirwan said the state's public college system has made strides in national rankings, in redesigning courses to appeal to tech-savvy students and in narrowing the achievement gap between white and minority students.

Drone Crashes Into Building In St. Louis
FBI Investigating Drone Crash On 30th Floor of St. Louis’ Tallest Building (Video) | The Gateway Pundit
Police are investigating whose drone crashed into the Metropolitan Square Building in downtown St. Louis Monday afternoon.Drone found on 30th floor balcony of Metropolitan Square Building | FOX2now.com
Authorities say someone found a DJI Phantom Two Quadcopter drone on the balcony of the building's 30th floor around 4 p.m.
Police believe someone crashed the drone into the building before it landed on the balcony. The model of drone is controlled by someone on the ground through Wi-Fi and features a high-definition camera. It retails for about $1,300.
The Federal Aviation Administration requires civilian drone operators to remain within sight of their drones and fly no higher than 400 feet above ground. Commercial drone use is banned by the FAA, which is investigating the incident

Inmarsat Chief Exec Blasts Iridium Plans in Maritime Safety, Air Navigation | SpaceNews.com
Rupert Pearce said Iridium’s current network is incapable of providing the minimum reliability required by the International Maritime Organization, and that Iridium has yet to demonstrate it can fully finance and deploy its second-generation constellation.
...
“While we obviously welcome competition and innovation around GMDSS and safety services generally, the most important thing is that the standards of quality for safety services are maintained, if not enhanced,” Pearce said.
“Fundamental to that is 99.99 percent availability on your network. We do not believe that Iridium even comes close to that level of performance. As such, it is utterly inappropriate that they should even apply, let alone be granted accreditation.
“Lives will be lost if people install that equipment and it’s not available when they need it. In the context of a safety service, as opposed to a commercial service, the consequences are ghastly to think about.

Eric Larsen Reports Reaching North Pole Across Arctic Ocean using Iridium

Polar Adventurer Eric Larsen Successfully Reaches North Pole After 480-Mile Unsupported Traverse... -- BOULDER, Colo., May 7, 2014 /PRNewswire-iReach/ --
Larsen, an accomplished polar adventurer who
in 2010 was the first person in history to successfully complete
expeditions to the South Pole, North Pole and the summit of Mount
Everest in a continuous 365-day period, described it as "one of the most
difficult expeditions" he has undertaken. Larsen and Waters travelled
across the 480-mile stretch of shifting sea ice using skis, snowshoes,
and at times, swimming through open water sections.
"You
know an expedition is tough when getting stalked by polar bears – who
are known to actively seek humans and attack them when hungry – is the
least of your worries," Larsen said by way of an Iridium satellite
phone, just minutes after reaching the Pole.
The duo did not receive any
outside assistance or supplies during their 53-day journey, hauling all
of their food and equipment in lightweight Kevlar sleds - which weighed
325 pounds at the start - that were 'rafted' together for larger open
water crossings. On one occasion, Larsen and Waters were followed by two
polar bears that came within 15 feet of their sleds. The team also
dealt with unusually thin ice, soft slush-like snow, severe windstorms,
pressure ridges, and moving ice that pushed them backwards.

For my own amusement, I've prepared a self paced web based guide to the San Diego Air & Space Museum. While going through the museum and looking at the exhibits, you can click and find out more information, as well as see videos of the planes in flight.San Diego contributions to aviation and space are emphasized in this museum, which is affiliated with the Smithsonian. A lot of effort has been spent in recovering from the 1978 fire. There is a lot of information on the museum website, but I decided to build my own web based guide. I recently purchased a Balboa Park explorer pass which gives general admission to all the major Balboa Park museums for a year, so I will be spending some time here.
Some pictures from my visit to the San Diego Air and Space Museum on May 8, 2014. The museum is located at the south end of Balboa Park in a circular building laid out as shown above, which is a scan of the map you get as you enter through the rotunda. Below is the view from the parking lot entry area.
There are a few dynamic, interactive, and multimedia exhibits, but most of the volume is taken up with static displays of memorabilia, some actual working aircraft, and scale models, replicas, and mockups. I've added links to supplementary material. There is good wi-fi in the museum area, so if you have a tablet or smartphone, you can use it to supplement the exhibits.
