(PhysOrg.com) — Nokia is showing off a prototype that location enthusiasts consider the next step in indoor mapping. Nokia has built a Location Extension Protocol on top of the Bluetooth 4.0 specification, which enables a phone user to see what Nokia says are highly accurate 3-D maps of indoor environments. While that kind of function may seem pointless when moving around in a small apartment, it is far more important for what Nokia has in mind. “We want to take what’s been done in navigation outdoors and bring it inside,” said Nokia’s Fabio Belloni, principal researcher at the Nokia Research Center. The Bluetooth tags on the device were controlled by a Nokia N9 smartphone, in a room with four sensors that were mounted on the ceiling. Another screen showed the helicopter being tracked in realtime on all three axes. While the Tuesday demo was for gaming purposes, the possibilities for use of an indoor 3-D mapping system are far-ranging. An attractive and obvious phone-service feature would be in navigating one’s way through exhibit halls or any other large buildings where mapping support can help users locate what they need to locate easily.The Nokia technology is a concept for now but Nokia plans to take the technology further. Nokia has plans to get this technology standardized with the Bluetooth SIG so that it can be put into consumer products by 2013. The Bluetooth Special Interest Group is the body that oversees the development of Bluetooth standards and technology licensing to manufacturers.

Retail analytics is another area that might make use of the indoor mapping system. Nokia’s prototype involves Bluetooth 4.0 on the phone or on a tag, along with locator equipment installed in ceilings to create 3D maps that are said to be accurate up to 21cm.Nokia on Tuesday gathered an audience of 30, both chip makers and service providers, at its Sunnyvale, California, site to demo the prototype. Nokia put a Bluetooth tag on a Parrot Drone. (Parrot is the company known for wireless Bluetooth devices. Its Drone is a helicopter device that connects to phones in a way that users can pilot the device using onscreen controls.) The room had Bluetooth Low Energy antenna arrays mounted on the ceiling to triangulate the drone’s location realtime.

Citation: Xerox to offer ‘Ignite’ software upgrade for copiers to let them grade school papers (2013, May 9) retrieved 18 August 2019 from https://phys.org/news/2013-05-xerox-ignite-software-copiers-grade.html Teacher influence persists in early grades Most everyone is familiar with standardized test forms—bubbles are filled in to indicate answers and a machine grades them by reading the bubbles. This new software from Xerox takes that concept to a whole new level by allowing a copy machine to grade non-standardized test forms. Tests and quizzes are given and students write down their answers using numbers, words, etc., all in their own handwriting. Those papers are then fed into the copy machine which automatically grades them all and sends both reports and grades to the teacher via a website. The idea is to reduce the amount of time teachers spend grading tests so they can spend more time in direct instruction. (Phys.org) —Xerox, the copy-machine giant, has announced that it will be selling a software upgrade for its copiers that will turn many of them into test grading machines. Called Ignite, the software not only grades papers, it analyses the results and produces reports for the teacher. © 2013 Phys.org Impressively, the new software can be used on virtually any kind of test: math, science, history, even essays. To do that, it works differently on different types of tasks. It can do normal grading for example, when there are clear answers, such as a single number answer to a math problem. For essays, it works more like a word processor, highlighting spelling and punctuation problems.What’s perhaps most revolutionary about the new system, however, is its ability to highlight certain types of data. If every child is having problems with a certain class of math problems, for example, the software can highlight that for the teacher so he or she can review those concepts in a new way. The software can also highlight problem trends for individual students too, setting up a scenario whereby teachers can assign customized homework—an idea that has long been little more than a dream for teachers.The system has already been extensively tested in many schools throughout the United States and Canada, and by all accounts is thus far a hit with teachers and students alike. Xerox plans to roll out the software to any interested school for the 2013-2014 school year. Explore further read more

It was during a drinks break of the Vijay Hazare Trophy match between Tamil Nadu and Karnataka on Monday that KL Rahul got the news of his selection in the Indian Test team for the tour of Australia but he said he was only concerned about winning the ongoing match at that time. ‘We were fielding when the substitute fielder came at the drinks break to inform me about my selection,’ Rahul said on Monday. ‘If I have got results this season, it was because of the hardwork put in during off-season with my coach Samuel Jayaraj. Once I am back in Bangalore, I am planning to practise against the wet tennis balls from 18 yards and also with plastic ball on concrete pitches to reduce my reaction time for strokes,’ said Rahul.

Change nahi hai madam, toffee le lo,” (We don’t have change, take some candies) is often the well-versed suggestion shopkeepers give when you are unable to pay them the exact amount. Now to make the most of your money you are forced to buy a couple of toffees which get dumped and forgotten inside your bag until that rare day when you decide to de-clutter it!Is the availability of change so rare that they always keep a jar or two handy to stuff some colourful wrappers into your hands with a smile? At times there may be crisis of the jingles but there are also situations when some vendors willingly or lazily hand over little somethings to round off the bill. Also Read – ‘Playing Jojo was emotionally exhausting’Where do all the coins go? Have they stopped making coins in the mints or are there some voracious coin collectors who desperately grab them all and never let them go? Who are the members of this chillar party?As a child, I remember being extremely happy when a shopkeeper used to be generous enough to give me candies rather than unnecessary coins which always used to slip off the gap of fingers and made me hover around over and after the rolling metals. Similarly, when children are sent to shops to collect some items they come back with some more. Also Read – Leslie doing new comedy special with NetflixSuddenly the other day I discovered that the child within me craves for these candies! As the man behind the counter gave me some unknown candy I demanded to know whether he had the ones I liked. He stared at me for a while as if to confirm that it was me who enquired, the same way some websites need you to type irrelevant codes to clarify you are not a machine! Then he went around looking for the one I had asked for and finally came with a shameful smile declaring that he does not have it. Exactly at that time from the hindsight I saw it deep inside a jar full of miscellaneous candies and I pointed it out with great enthusiasm. To this, he looked both defeated and relieved, and struggled to get it out from the jar for me. It somehow felt special, as if choosing the forced gift was a right to be enjoyed by one and all. If they are making you buy one, you better get the best of the lot, uncompromisingly. Yet again, it is not worth it, since you have to remember to have them or they would just rot somewhere in a corner.There are also some firm customers who stick to what they need and come up with a no-nonsense face declaring that they won’t accept unimportant titbits. That is when the hidden treasure comes jingling its way out. Another and very frequently practiced custom is to remember or note down the amount to be received by either parties, and eventually rounding it off on the next purchase. But this practice is only viable when you have developed a cordial relation with the shop attendant. This menace of ‘demanding change’ is not new and is not restricted to shopkeepers alone. In cities like Kolkata where travelling short distances is easy via autos the auto drivers create a pandemonium in case you are unable to pay him the exact amount. Similar cases happen in Delhi with customers and regular office goers when the vendors and rickshaw pullers complain of not having enough change. Either you keep losing Rs 5 everyday or you argue and find a way out (which usually nobody does, due to lack of time).With this menace dancing around the country, it is time to get a ‘change’ and control the change crisis before it gets too late and we are left to suffer the ill balanced eco(nomic)-system with the extinction of coins. read more
KOLKATA: The Bengal government has a plan to introduce merchant mining in the state for which it may seek the Centre’s approval, State Industry, Commerce and Enterprises Minister Amit Mitra said on Wednesday.He was speaking at the ‘Global Mining Summit 2018’ organised by the Confederation of Indian Industry (CII) at Eco Park. Mitra said the state government will consider if merchant mining could be done at Deocha Pachami — the largest coal block in Asia and the world’s second largest reserve with 2,102 MT. Also Read – Rain batters Kolkata, cripples normal life”We think the amount of coal reserve Deocha Pachami has is not meant only for capital plants to generate power. A small proportion of the reserve will be used for power generation while the rest will be available for non-captive use. We have to consider merchant mining for future and see if the quantum of coal raised from this mine is greater than what the power companies will require,” Mitra said. He further said the state government will talk to the Centre in this regard for its approval. Once the government starts using Deocha Pachami for merchant mining, the private sectors will be roped in. Deocha Pachami has been allocated to the state government by the Centre and it is fully-owned by West Bengal Power Development Corporation Limited (WBPDCL). Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killedThere will be a direct investment of Rs 12,000 crore at Deocha Pachami, while the indirect investments would be five times higher. There will be an employment of 1,10,000 people (more than 1 lakh people). Currently, the state government has 228 mines in Ranigunj and Asansol region. Deocha Pachami will be used for Sagardighi phase II and phase III and Santaldih as captive mines, Mitra maintained. The minister added that Bengal has 35 billion tonne of coal reserve, consisting of high value coal with low sulphur and low ash content. Bengal is among the few states to have Coal Bed Methane (CBM). Various international collaborations are taking place in the state, he said. Bengal also has plans to set up a logistic hub in the state as it has an access to countries like Nepal, Bhutan, Bangladesh and ASEAN. “The amount of revenue collected from minor and major minerals in the state stands at Rs 2,264 crore – Rs 574 crore from minor minerals and Rs 1,690 crore from major minerals. When we came to office, the revenue from minor mineral was only Rs 88.6 crore. The amount has increased because of the transparency and the integrity that have been incorporated into the system. The revenues have been lent to social and physical infrastructure. We have been given 5 exploration proposals through mineral exploration coverage. We are working on it,” Mitra said. Bengal government is keen on setting up an equipment manufacturing hub. It’s one of the visions of this government. The matter has already been discussed with the state government, Mitra further maintained. read more
