A team at the University of Portsmouth has already developed software which enables cameras to spot visual clues to anything from violent crime to vandalism, by looking for tell-tale signs such as someone raising their arm suddenly or even a snapped car aerial.

Now the artificial intelligence software is being taught to recognise sounds which are associated with crimes, including breaking glass, shouted obscenities and car alarms going off. Cameras which ‘hear’ the sounds will automatically swivel to the direction they have come from, and will alert the person monitoring the system to a possible crime in progress.

Dr David Brown, who is leading the team at the university’s Institute of Industrial Research, said: “We have already developed visual recognition software, but the next stage is to develop audio recognition software to listen for particular sounds.

“We can teach the cameras to listen out for things like a swear word being shouted in an aggressive way, or for other words which might signify a crime taking place. The camera will be able to swivel to the direction of the sound at the same speed someone turns their head when they hear a scream, or about 300 milliseconds.

“People monitoring CCTV images have banks of screens in front of them, and this system helps them by alerting them to something the system has spotted. The person looking at the screen can then quickly identify if it is a crime taking place, or whether the camera has simply picked up on something innocent, like a child screaming, and act on it accordingly.”

Justice Secretary Jack Straw said there was a real need for some witnesses to have their identities protected.

Mr Straw told BBC Radio 4’s Today programme that the law will be changed “as quickly as possible”.

The ruling quashed the murder conviction of a man who was convicted with the aid of anonymous evidence.

Police have warned that serious criminals could walk free as a result.

“I am looking at this very urgently indeed,” Mr Straw said of the ruling, which applies to criminal cases in England, Wales and Northern Ireland.

He said the reality of violence and intimidation in some criminal circles means accommodations must be made within the rules of evidence.

Testifying to the House Energy and Commerce Committee, Michael Masters of Masters Capital Management said that the price of oil would quickly drop closer to its marginal cost of around $65 to $75 a barrel, about half the current $135.

Fadel Gheit of Oppenheimer & Co., Edward Krapels of Energy Security Analysis and Roger Diwan of PFC Energy Consultants agreed with Masters’ assessment at a hearing on proposed legislation to limit speculation in futures markets.

Krapels said that it wouldn’t even take 30 days to drive prices lower, as fund managers quickly liquidated their positions in futures markets.

“Record oil prices are inflated by speculation and not justified by market fundamentals,” according to Gheit. “Based on supply and demand fundamentals, crude-oil prices should not be above $60 per barrel.”

Futures trading in London has not been a major factor in rising oil prices, testified Sir Bob Reid, chairman of the Chairman of London-based ICE Futures Europe. Rising prices are largely a function of fundamental supply and demand, not manipulation or speculation, he said.

“Energy speculation has become a growth industry and it is time for the government to intervene,” said Rep. John Dingell, D-Mich., chairman of the full committee. “We need to consider a full range of options to counter this rapacious speculation.” It was Dingell’s strongest statement yet on the role of speculators.

Dingell introduced a bill on June 11 that would ask the Energy Department to gather the facts on energy prices, including the role played by speculators.

There are two kinds of speculators in the futures markets, Masters said. Traditional speculators are those who need to hedge because they actually take physical possession of the commodities. Index speculators, on the other hand, are merely allocating a portion of their portfolio to commodity futures.
Index speculation damages price-discovery mechanisms provided by futures markets, Masters added
The committee will likely consider legislation that would rein in index speculation by imposing higher-margin requirements; setting position limits for speculators; requiring more disclosure of positions; and preventing pension funds and investment banks from owning commodities.

Both major presidential candidates have supported closing loopholes that encourage speculation in the energy markets. Read more on Election Blog.

However, other witnesses said that pure speculators have had little impact on energy prices, which have doubled in the past year to about $135 per barrel. Both Treasury Secretary Henry Paulson and Energy Secretary Samuel Bodman have dismissed the impact of speculators on prices paid by consumers.

Speculators now account for about 70% of all benchmark crude trading on the New York Mercantile Exchange, up from 37% in 2000, said Rep. Bart Stupak, D-Mich., chairman of the investigations subcommittee. Stupak introduced a bill on Friday that would limit index speculation.

There has been much discussion recently about how big a role speculators have been playing in the sharp rise in energy prices, though no consensus has emerged on this point.

Congress, however, has grown increasingly concerned over speculative investors’ role in the energy market in comparison with those buying futures contracts to hedge against risk from price changes. Lawmakers are expected to consider legislation to set strict limits — or in some cases, an outright ban — on speculative trading in energy futures in some markets.

Dingell is looking into any legal loopholes that may have contributed to speculation in energy markets. In 1991, according to documents provided by the Commodity Futures Trading Commission to the committee’s investigators, the agency authorized the first exemption from position limits for swap dealers with no physical commodity exposure. This began what Dingell said was “a process that has enabled investment banks to accumulate enormous positions in commodity markets.”

Is Congress barking up the wrong tree?

Neal Ryan, manager at Ryan Oil & Gas Partners, said that if Congress develops regulations to cut back speculative trading, speculation will just find a new home.

“Speculation is the root of capitalism,” he said. “If the speculation is forced out of the U.S. exchanges, it’ll simply show up on other exchanges that are OTC like the ICE, or new exchanges will pop up to allow for the spec trades to continue functioning.”

Ryan said he does see a reason for Congress to look at eliminating aspects such as allowing West Texas intermediate crude oil futures to trade on foreign markets and the “Enron loophole,” but “these exchanges are currently functioning as they are supposed to in a free marketplace.”

Heavy rains this spring came when the soil was most vulnerable to erosion – when the soil has been tilled for planting, but before plants’ root systems grow to hold it in place, he said.

It isn’t known yet how much damage was done to soil conservation structures, Northey said, but he expects the state Legislature will need to provide a fresh infusion of money to repair the damage.

All protocol was dropped as the man’s body fell from a high vantage point and a shot rang out. Mr Sarkozy and Ms Bruni were surrounded by their secret service agents and hastily bundled aboard their plane.

Security guards for Ehud Olmert pulled out their handguns and hustled the Israeli Prime Minister and his entourage into waiting bullet-proof limousines.

When the incident ended, however, Mr Olmert and Shimon Peres, the Israeli President, boarded the Sarkozy plane to say a proper goodbye.

Israel Radio said that the officer who died was about 100m away from the Sarkozy plane as it waited on the runway at Ben Gurion, Israel’s largest international airport. Two women soldiers who witnessed the incident fainted and were treated by medics.

The policeman apparently fell from a vantage point on a high building, where he had been guarding the event. Reports suggest the policeman shot himself in the head. “This was in no way an assassination attempt,” said Micky Rosenfeld, a police spokesman. “A border policeman … committed suicide during the farewell ceremony.”

According to Mr Rosenfeld, the guard who shot himself was a paramilitary policeman and had been assigned to a security patrol at the airport.

She is living out of her shabby 1978 RV, and every night she has to look for a place to park where she won’t get hassled by the cops or insulted by residents.

“I’m not a piece of trash,” the former home health-care aide said as she stroked one of five dogs in her cramped quarters parked in the waterfront community of Marina del Rey.

Amid the foreclosure crisis and the shaky economy, some California cities are seeing an increase in the number of people living out of their cars, vans or RVs.

Acting on complaints from homeowners, the Los Angeles City Council got tough earlier this year by forbidding nearly all overnight parking in residential neighborhoods such as South Brentwood.

Slowly, he turned that wooden plank before a series of mirrors that had been placed inside an aluminum frame, until the wood caught fire.

That was quite a moment, recalled Matthew Ritter, one of the onlookers.

“Let’s just say it was a small combustion for wood materials, but a giant explosion of solar energy,” he said.

Ahrens, Ritter and the other people who helped create the solar-powered dish that harnessed the sunlight that eventually burned the wood say they’ve just created the world’s most cost-efficient solar power system.

They also say these dishes may revolutionize global energy production.

“You can stick these things wherever there is a piece of sunlight, and power a home or an industrial plant,” said Ahrens, who just received his master’s degree from MIT.

Since January, he’s been working with Ritter, an Olin College student; Micah Sze, a recent graduate of MIT’s Sloan School of Management; University of California-Berkeley graduate and Broad Institute engineer Eva Markiewicz and MIT materials science student Anna Bershteyn.

Together, they built a 12-foot wide solar panel by piecing together lightweight aluminum tubes to make the frame. Inside, they arranged a series of mirrors and then attached a water-filled coil at the bottom of the frame.

When the frame is properly positioned, the mirrors will direct concentrated sunlight toward the coil.

As the water heats up, it is converted to steam, and that steam, the creators say, can be used to generate electricity to heat and cool homes and power machines.

They now say its design is so simple, it can be built and placed just about anywhere the sun shines.

“We made it by hand and transported the parts by car or by bike,” Ritter said.

The crew spent about $5,000 to build the dish, and according to MIT Sloan School of Management lecturer David Pelly, it is the cheapest way he’s seen to harness that much sun power.

“I’ve looked for years at a variety of solar approaches, and this is the cheapest I’ve seen,” he said.
