English to Thai: New tech could mean 3D movies with no glasses General field: Tech/Engineering
Source text - English Watching 3-D movies generally means suffering through two things: crappy plotlines that favor spectacle over substance and the need to wear some annoying, dorky glasses. Scientists may have solved one of these frustrations. (You might be able to guess which.)
Researchers in South Korea have created a new method that would allow moviegoers to simply sit down and start watching a 3-D movie with no extra gear necessary. The research was published Monday in Optics Express.
"This is essentially the next step that was required for 3-D display technology without glasses," said physicist John Koshel, who studies optical science at the University of Arizona and was not associated with the new work.
We see the world in three dimensions because our eyes are spaced slightly apart, each looking out at a different angle. Your brain combines the information from both eyes, determining where each object in your field of view is to generate depth perception.
To achieve 3-D movies or television, the trick is to send a slightly different, offset picture to each eye. Special glasses handle this task for most modern 3-D blockbuster movies, with each lens only letting in one polarization of light. Polarization describes the direction in which the electromagnetic waves in light oscillate, either up-down, left-right, or something in between.
When you sit down to watch something like "Avatar," two projectors are displaying two images on the same screen, with the light from one polarized left-right and the other up-down. This is why the screen looks kind of blurry when you take the glasses off -- there are two movies playing on it at the same time. The 3-D glasses correct the situation by separating these images, allowing the left-projector movie to go to your left eye and the right-projector movie into your right.
But needing two projectors perfectly synced in a theater is awkward and expensive. There are some glasses-free methods around, where a special filter covering the screen sends some of the light to your right eye and some to your left, creating a 3-D image. This is the technology in Nintendo's 3DS gaming system and several smart phone displays, such as the HTC Evo 3D. In a movie theater, this glasses-free 3-D technique would require the projector to sit behind the screen, but most theaters are not designed for this.
The new method would allow movie theaters to keep their projectors where they've always been, behind the audience, and uses fairly simple optical technology. A special array sits in front of the projector and polarizes its light. A filter covering the screen then obscures different vertical regions of the screen, like the slats of venetian blinds. Each of your eyes, sitting at a slightly different angle, has some of the screen blocked and some of the screen visible. The movie has the right-eye and left-eye images interleaved in vertical columns with one another. The trick then is to have the light visible to your left eye contain the left-eye pixels and vice versa for the right eye.
The new method is less cumbersome than both the current two-projector and the behind-the-screen-projector methods. But because it blocks some of the light to your different eyes, the current image resolution is fairly low. Koshel expects that 3-D movie companies will be interested in upgrading the method's abilities and resolution to bring glasses-free 3-D to the masses.
"This technology is still in its infancy, but it's a new step that was hidden for a long time," Koshel said.
English to Thai: Democrat duo testify to rally deaths probe General field: Other Detailed field: Government / Politics
Source text - English Democrat leader Abhisit Vejjajiva and the party's MP for Surat Thani Suthep Thaugsuban Monday testified to the Department of Special Investigation over the crackdown on the red-shirt rallies.
They were both confident they demonstrated that they had acted legally.
The two men, who were in charge of directing state measures against the demonstrators, are accused by the red shirts of involvement in the 91 deaths of protesters and soldiers, most of which took place during clashes at the Khok Wua and Ratchaprasong intersections in April and May 2010.
Mr Abhisit recalled the events Monday while he was questioned by DSI investigators for up to seven hours, as the officers wanted him to check his testimony.
"I based my clarification on facts," Mr Abhisit said.
The former prime minister, who arrived with documents relating the events in chronological order, explained what his government did from its initial responses to the protesters to its decision to crack down on them.
"There's no worry at this stage," he said, referring to the DSI's ongoing investigation into the deaths.
The fatalities occurred once the rally turned more violent, with shooting and arson attacks later taking place both in Bangkok and upcountry.
On April 6, 2010, during the lead-up to the violence, Mr Abhisit, then the prime minister, addressed the public through a TV broadcast that his government would stick to the country's laws and policies of tolerance in dealing with the red-shirt demonstrators.
Among its first measures, the government sent officers to the rally venue to tell protesters the gathering was illegal, Mr Abhisit said.
However, the demonstrators, under the leadership of the pro-Thaksin United Front for Democracy against Dictatorship which demanded the Abhisit administration dissolve the House for new elections, continued rallying and brought about disorder, he said.
Some red-shirt co-leaders violated the emergency decree to break into the parliament compound while some supporters caused the evacuation of patients at Chulalongkorn Hospital during their raid to search for soldiers believed to be hiding there, he said.
Mr Suthep, then deputy prime minister and director of the Centre for the Resolution of the Emergency Situation (CRES), helped Mr Abhisit handle the rally, but was later viewed by some people as a "plaintiff" in the event.
However, looking back at the CRES measures against the protesters, Mr Suthep is confident the actions were considered carefully by CRES members.
"I'll tell only the truth," Mr Suthep said before testifying to DSI investigators yesterday.
"I think I have an advantage because I took note of what everyone said and argued in each meeting," he said.
DSI chief Tarit Pengdith was asked by reporters whether he also needs to provide his account of events to investigators because he was also a CRES member.
He said he did not as he was only a state official who "never joined the [CRES] meeting on strategic planning".
Mr Suthep submitted 200 pages of documents and CRES minutes to the DSI as evidence yesterday.
He chose to reserve his opinion when asked whether he is confident about the outcome of the probe and about his response to Mr Tarit's claim, except to say that "Mr Tarit stayed with me then and gave useful suggestions".
My name is Peerapol Chongchirasiri from Thailand, my native country. I have skills in both Thai and English language. Because I graduate in bachelor degree in Industrial Engineering, I have knowledge in Engineering such as mechanic, electric, and industry. After I received diploma, I was immediately working at CP Food Manufacturing, the biggest food industry in Thailand. During working there, I worked as Engineer and Purchasing Supervisor, and I learned about food quality control and industrial management such as HACCP, GMP, ISO9001, and Food Hygine. Unfortunately, after working with enthusiasm for two years, I decided to resign from my work because I want to study in further education.
When I have free time, I usually look into computer technology, softwares, and reading international news. Moreover, not only am I professional in using Microsoft Office, but also I often practice in using CAD programs such as SolidWorks and AutoCAD.
Nowadays, I apply to study in Master's Degree at Business in UK. Finally, I wish with my knowledge and work experience will can help others who have problem in understanding between English and Thai language.
