Citation: Hi3G Access releases a video and still image sharing system for e-commerce (2011, April 12) retrieved 18 August 2019 from https://phys.org/news/2011-04-hi3g-access-video-image-e-commerce.html © 2010 PhysOrg.com Explore further University of Washington testing sign language video phones More information: www.b-reel.com/projects/3live-shop/ and www.tre.se/Privat/Ovriga-sidor/3LiveShop/ (in Swedish) (PhysOrg.com) — Hi3G Access, a Swedish-based phone company, has developed a video chat system that allows users to shuffle images on the screen with their hands. The system, which you can see in the video below, is known as 3LiveShop. 3LiveShop is a Flash-based multitouch system that is, at the current moment, being used as a sales tool for Hi3G Access. In order to create this tool Hi3G Access collaborated with a Stockholm-based production company known as B-Reel. The setup is very similar to a Skype chat, in which you are able to see a smaller image of yourself in the upper right-hand corner of the screen.The system is unique, because it allows for the video chat to be shown at a lower resolution, while still images can be shown at a higher resolution. This is achieved by the use of two different streams, one for the video and one for the still images.The system is even tied into an e-commerce system. After having a chat with the sales person online, the customer can see a bill and add then add their new mobile phone, the products that Hi3G Access sells, and pay for it right then and there. The entire system is coded in Adobe Flash, which may be a choice that was made with larger scale distribution in mind, as Flash is a fairly common program.The multitouch screens, which were also developed in conjunction with a company called Teenage Engineering, use a system of mirrors and high-end cameras to create the video feed for chat. There are currently only three of these workstations functioning in the world, but if the program is successful the company hopes to expand the program.This begs only one question. If most of us shop online in order to avoid sales clerks, why would you want to video chat with one? This document is subject to copyright.

With such a system, students can gain a deeper understanding of how land and water systems interact and see for themselves how changes to topography over time cause changes in the environment in a much more hands-on fashion than when building static models out of sand, dirt or clay. Pico projector used in eye based video gaming system Explore further © 2012 Phys.Org (Phys.org) — Most children at some point in their schooling are taught about the water table and many wind up being tasked with creating a model of some sort to represent how it all works. Some use clay, but many more likely use sand, as it’s far easier and faster than most anything else. Now researchers at UC Davis have taken that model to new extremes by building a sandbox system that is capable of automatically adding augmented reality real-time coloring to the sand to indicate altitude and moving water as changes are made to the terrain with a hand or small tool.

Mico Tatalovic in New Scientist said that “This exotic, praying-mantis-like cockroach that lived at the same time as dinosaurs was caught in amber about 100 million years ago. It is part of a new family of extinct predatory cockroaches that hunted at night.”Dragos Mitrica in ZME Science said the insect was found at a mine in Noije Bum, Myanmar. “The specimen was one of many found in the area, and is related to today’s praying mantises. Out of all the predatory cockroach lineages that evolved in the Cretaceous, only praying mantises survive today.”Big predatory dictyopterans are represented mostly by praying mantises (Mantodea), which can be derived from extinct cockroaches. The authors described “the holotype specimen of a new species belonging to a morphologically-deviant new family.”They said this species was probably a pursuit predator, “filling a niche previously not exploited by extinct cockroaches.”The specimen was collected in a quarry in the Hukawng valley. The cockroach was found trapped in amber.The specimen was studied with a Leica M80 stereo microscope. They observed a male cockroach with detached right mid and hind femora. Its elongated head and large eyes were protruding beyond the head outline. All the leg segments were described as “extremely elongated and covered with dense setation (short trichoid hairs – sensilla chaetica).”As for the body, they wrote that “the preserved body length is about 4.5 mm, width is difficult to measure, but the body is very wide as in standard cockroaches (over 2 mm), a little narrower basally, pale, with black lateral maculas.”In their discussion section, the authors said that they endorsed “a reclassification of Dictyoptera, in which the order Mantodea is phylogenetically subordinate within the Corydioidea (=Polyphagoidea) – a superfamily that includes diverse extant but also extinct cockroaches sometimes placed within Dictyoptera but outside the standard order of cockroaches.”They said that the absence of spines on the walking legs suggested that this species was an active runner and pursuit predator, which evolutionarily lost the passive protection of spines.The authors felt that “the erection of a new family” was well justified as a result of “the unique habitus with numerous autapomorphies along with several plesiomorphies.”Vrsansky is from the Geological Institute, Slovak Republic; Bechly is from the State Museum of Natural History in Stuttgart, Germany.Vrsansky said in New Scientist that the specimen was one of dozens of preserved insects found in the area, making it the most important site of dinosaur-age amber in the world. Tatalovic wrote, “Many large pieces of amber contained complete adult insects, which should help reconstruct the history of the animals and their ecosystem.” © 2015 Phys.org Citation: Dinosaur-times cockroach caught in amber, from Myanmar (2015, May 1) retrieved 18 August 2019 from https://phys.org/news/2015-05-dinosaur-times-cockroach-caught-amber-myanmar.html Explore further Manipulator modificaputis gen. et sp. n.

The authors, Peter Vrsansky and Günter Bechly, from the Slovak Republic and Germany, respectively, said that “unique adaptations such as strongly elongated extremities and freely movable head on a long neck suggest that these animals were pursuit predators.”
Credit: CC0 Public Domain Once a year, honeybees, led by a queen, leave their nests in droves to find a new home. But because it takes some time to find a site and build a new nest, there is a period when they have no place to live. To protect themselves during this time, they congregate into masses that hang from tree branches—these clusters are made entirely of bees, each clinging to one another. In its most natural state, such clusters tend to form in the shape of a cone. But prior research has shown that the cone shape becomes flattened during inclement weather, such as when the wind blows. In this new effort, the researchers wondered how the honeybees knew what to do when adverse conditions arose. To find out, they gathered bees from the wild and put them in a container in their lab where they were allowed to form a cluster, dangling from a movable apparatus.Once a cluster formed, the researchers moved the apparatus to pull the cluster back and forth, simulating the impact of wind pushing the branch upon which they hung. As the researchers watched, the cluster slowly flattened, hugging the apparatus. A flatter shape, the researchers noted, would reduce pressure from the wind, just as it would for a person lying on the ground versus standing up. By studying slow-motion video of the bees and tracking the movement of those on the surface of the cluster, the researchers developed a theory—they believed that the bees, upon feeling pulled from the bees they were holding on to, moved themselves to a place of higher stress.To test this theory, the group created a computer simulation of the honeybees and their cluster and then gave those on the outer surface the ability to feel stress and to react to it by moving to a position of higher stress. They found the virtual bees changed the shape of their cluster in the same way as did those in the real one, offering strong evidence that their theory was correct.

In their paper published in the journal Nature Physics, the group describes their study of honeybee behavior in their lab and what the found. Journal information: Nature Physics More information: O.

Pink might not be the new black, but it surely is the colour of the season. October is internationally the breast cancer awareness month and Delhi is living it up to inform about this one disease that can be fully cured if detected early.Leading the pack was Hard Rock Cafe. Last year they had organised a session with well-known gynecologists from the city who spoke up to dispell the great cancer myth. While breast cancer has no specific risk, some facets can be kept in mind. Chances are high if she might be susceptible to the risk if she has a family history. The main precaution is not to ignore abnormalities if they arise and are detected, say doctors.

Organised by HRC this event- Pinktober, is one of their in month long series of events for their breast cancer awareness program. Geared up in white tees and banners in their hands all the participants gathered early morning at Gurgaon and walked till Hard Rock Cafe, Saket also there were a number of school students present to show their support.This is HRD’s 14th year of celebrating Pinktober. A tribute night was also arranged as a part of the series where participants had a lot of fun, choices to savour on from the especially created pink menu followed by live performances. People celebrated the courage of breast cancer survivors and their efforts to spread awareness. All the proceedings from these events will be donated to the charity Elle-Ogaan Cancer Foundation.
Kolkata: Housing Infrastructure Development Corporation (HIDCO) will observe the first-ever World Bicycle Day on Sunday in New Town. The United Nations has declared June 3 as World Bicycle Day this year and it will be celebrated globally. Bicycles are not only an eco-friendly mode of transport but also keeps the cyclists physically fit and mentally alert. It helps to reduce obesity and improves the cardiovascular system.In New Town, the celebration is more significant as it is the only place in India where the Cycle Sharing Scheme has been introduced and it has become extremely popular. Also Read – Heavy rain hits traffic, flightsHousing and Urban Development Corporation (HUDCO) under the ministry of Housing and Urban Affairs had awarded the scheme introduced by New Town Kolkata Development Authority (NKDA) in the Urban Transport category at a function in New Delhi in April.On Sunday, the World Bicycle Day will be celebrated with HIDCO keeping cycles in front of the golf course off Eco Park to be used by the enthusiasts. The ride is free and cycle lovers can take a ride to popularise cycling. Eco Park has a special zone where people come and do cycling and duo cycling as well and it is extremely popular among visitors.
