Chip makers start joint venture for improving Linux distribution

first_img Citation: Chip makers start joint venture for improving Linux distribution (2010, June 7) retrieved 18 August 2019 from https://phys.org/news/2010-06-chip-makers-joint-venture-linux.html The aim of the joint venture is to give open-source developers the software and tools they need to accelerate and simplify development of Linux for portable devices using ARM-based system-on-a-chip (SoC) designs. The founders say they will release tools, kernel and middleware software for a variety of SoCs based on the ARM Cortex-A processors every six months, beginning in November 2010.At present consumer devices use a variety of operating systems such as Apple, Windows, Blackberry, Intel, Palm, and Nokia’s Symbian. Linux operating systems in mobile phones are growing, and there are already a number of Linux versions that run on ARM chips, including Ubuntu and Debian. There is also a Red Hat Fedora Linux version for ARM, but it is not yet commercially available.Linux is the most popular open-source operating system available, and is a direct rival of Microsoft on personal computers and the open-source Symbian on phones. Google’s Android and MeeGo, LiMo and webOS are among the Linux operating systems, and the establishment of Linaro should simplify the development of Linux versions and accelerate their uptake, by enabling developers to concentrate on the user interface rather than the kernel and middleware. The inclusion in Linaro’s plans of MeeGo, which was developed by Nokia and Intel, suggests Intel will be involved at some stage, but the initial focus of the group will be on ARM chips.The other two companies that have signed up to the non-profit foundation are ST-Ericsson and Freescale Semiconductor, but other companies are welcome to join the group. The companies have pledged tens of millions of dollars a year to fund the project, according to the interim CEO of Linaro, Tom Lantzsch. The foundation will work with Linux to align their core operating principles, and will contribute to a variety of open source projects.The formation of the Linaro foundation was announced in Taipei in Taiwan on June 3 at the Computex trade show. According to Ben Cade, co-CEO, the present growth is in always-on, always-connected devices powered by SoCs, and the joint venture is expected to increase the numbers of such devices using Linux distributions.

New device may make converting waste heat to electricity industrially competitive

first_imgThe proposed thermoelectric device consists of many parallel nanowires with an external gate voltage that can be tuned to optimize the efficiency and power output for different temperature differences between the leads and different loads. Credit: Muttalib and Hershfield. ©2015 American Physical Society (Phys.org)—Currently, up to 75% of the energy generated by a car’s engine is lost as waste heat. In theory, some of this waste heat can be converted into electricity using thermoelectric devices, although so far the efficiency of these devices has been too low to enable widespread commercialization. More information: K. A. Muttalib and Selman Hershfield. “Nonlinear Thermoelectricity in Disordered Nanowires.” Physical Review Applied. DOI: 10.1103/PhysRevApplied.3.054003 Although the physicists’ theoretical analysis suggests that the proposed device could have significant performance advantages over current devices, they caution that it’s too early to make any definite estimates.”Any estimate at this point is going to be unreliable because there are so many ways to lose heat in any practical device that our theoretical proposal does not take into account,” Muttalib told Phys.org. “Even then, we gave a very crude estimate in our paper where both the efficiency and power output can be tuned (with a gate voltage) to be significantly larger than any commercial device currently available. Note that there are other theoretical proposals with large efficiency but without sufficient power, and therefore not practically usable.”Most importantly, the physicists hope that the new ideas presented here may inspire new ways of thinking about thermoelectric technology.”Perhaps the greatest significance is a possible shift in paradigm in the design of thermoelectric devices,” Muttalib said. “Currently, the focus of the community is overwhelmingly in the so-called ‘linear response’ regime (where the temperature and the voltage gradients across the material connecting the hot and the cold leads are small); the performance of such devices depends solely on the properties of the connecting material. This has kept the current efforts limited to finding or designing a ‘good’ thermoelectric material. Our work suggests that, in the ‘non-linear’ regime, the performance of the device also depends crucially on the parameters of the leads and the loads; the optimization of performance in such cases has many more interesting possibilities to be explored.”Although this work offers many new possible directions for future research, Muttalib and Hershfield hope that it will be other scientists who move the technology forward.”We are both theoretical physicists doing research in basic sciences, and in particular we are not experts in device technology,” Muttalib said. “We stumbled upon the current idea while trying to understand the effects of non-linear response on electron transport in nano systems. We hope that experimentalists and device engineers will find our work interesting and will pursue it to build an actual device. Our next plan in this general area is to understand, again at a very fundamental theoretical level, the effects of phonons or lattice vibrations in nano systems in general; these effects are known to be important for thermoelectric devices as well.”The nanowire-based thermoelectric device isn’t the only new thermoelectric design to appear recently. In the same issue of Physical Review Applied, Riccardo Bosisio, et al., at Service de Physique de l’Etat Condensé in France have developed a thermoelectric device in which the electrons travel through the nanowires by “phonon-assisted hopping,” where the phonons are vibrations that carry heat. Explore further Company developing commercial tech to convert heat to electricitycenter_img Now in a new study, physicists have demonstrated that a thermoelectric device made of nanowires may achieve a high enough efficiency to be industrially competitive, potentially leading to improvements in fuel economy and other applications.The scientists, Khandker A. Muttalib and Selman Hershfield, both physics professors at the University of Florida in Gainesville, have published a paper on the new thermoelectric device in a recent issue of Physical Review Applied.In addition to recovering energy from the waste heat in combustion engines in vehicles, thermoelectric devices could also perform similar functions in the engines of ships, as well as in power plants, manufacturing refineries, and other places that produce large amounts of waste heat.In their paper, the scientists explain that using bulk materials in thermoelectric devices has turned out to be inherently inefficient, but nanoengineered materials appear to be more promising. The new device consists simply of two large leads at different temperatures connected by several noninteracting, very thin nanowires. Each nanowire transmits current from the hotter lead to the colder lead, and many nanowires in parallel can scale the power up to high levels.One of the biggest challenges facing thermoelectric devices is that the conditions that optimize a device’s efficiency and power output are different for different temperature gradients between the two leads as well as for different electrical loads (how much power is being consumed at a given moment). Because of this complexity, the optimum device for a particular temperature gradient and load may not work nearly as well for a different temperature gradient or load.The researchers here found a way around this issue by applying a voltage to the nanowires, which allows power to be transmitted along the nanowires only at energies above a certain value. This value depends on the temperature gradient and the load, which vary, but the applied voltage can also be varied in order to tune the power transmission and simultaneously optimize the device’s power and efficiency. Using nanowires to connect the leads also has a practical advantage compared to using other materials. While many other candidate materials are difficult to manufacture reliably, nanowires can be manufactured reliably and controllably, which is important for realizing the precise optimum dimensions.

Ultrasensitive magnetometer proposed based on compass needle

first_img © 2016 Phys.org Citation: Ultrasensitive magnetometer proposed based on compass needle (2016, May 18) retrieved 18 August 2019 from https://phys.org/news/2016-05-ultrasensitive-magnetometer-based-compass-needle.html Current magnetometers are very sensitive, able to detect levels of magnetism that are approximately a trillion times less than that of the Earth’s magnetic field. They achieve this feat by taking advantage of the wobble that occurs when an atom is placed in a magnetic field—such magnetometers are made by placing cells of atomic gas in a magnetic field, the wobbles of the atoms are averaged to arrive at a single measurement. In this new effort, the researchers suggest that a new way to measure magnetic fields could be perhaps as much as 1000 times more sensitive.The idea behind the still theoretically magnetometer comes from the way a compass needle works—instead of wobbling when exposed to a magnetic field, it simply lines up—at least when viewed from a distance. The researchers have shown that such needles do actually wobble like atoms, when they are very small and placed in a very weak magnetic field. They envision a very tiny needle made of cobalt with all of its atoms aligned in a single direction. When the needed is placed in a weak magnetic field, the angular momentum of the rotation of the needle would be a lot smaller than its intrinsic spin angular momentum, which means it would precess, very much like single atoms do. Measuring the precess then would offer a means of measuring the level of magnetism.Constructing such a magnetometer they acknowledge, would be challenging. The team believes their needle would be approximately 10 micrometers long, with a radius of 1 micrometer. The trick would be in isolating such a needle from external noise. It would have to be held at a very low temperature, somehow protected from detecting the Earth’s magnetic field, and be held without being touched, perhaps levitated by a superconductor. Measuring the precess would be tricky was well, likely requiring a super-conducting quantum interference device, which would likely also be the limiting factor in the final product. , arXiv (Phys.org)—A team of researchers with members from several institutions in the U.S. and one in Germany has proposed the idea of using an extremely small compass needle to build an ultrasensitive magnetometer. In their paper published in Physical Review Letters, the team describes their idea and the possibility of such a device actually being built. Explore further Journal information: Physical Review Letters More information: Derek F. Jackson Kimball et al. Precessing Ferromagnetic Needle Magnetometer, Physical Review Letters (2016). DOI: 10.1103/PhysRevLett.116.190801 , On Arxiv: http://arxiv.org/abs/1602.02818ABSTRACTA ferromagnetic needle is predicted to precess about the magnetic field axis at a Larmor frequency Ω under conditions where its intrinsic spin dominates over its rotational angular momentum, Nℏ≫IΩ (I is the moment of inertia of the needle about the precession axis and N is the number of polarized spins in the needle). In this regime the needle behaves as a gyroscope with spin Nℏ maintained along the easy axis of the needle by the crystalline and shape anisotropy. A precessing ferromagnetic needle is a correlated system of N spins which can be used to measure magnetic fields for long times. In principle, by taking advantage of rapid averaging of quantum uncertainty, the sensitivity of a precessing needle magnetometer can far surpass that of magnetometers based on spin precession of atoms in the gas phase. Under conditions where noise from coupling to the environment is subdominant, the scaling with measurement time t of the quantum- and detection-limited magnetometric sensitivity is t−3/2. The phenomenon of ferromagnetic needle precession may be of particular interest for precision measurements testing fundamental physics. A ferromagnetic needle with spin S = N~ along its long axis precesses at a frequency Ω in a magnetic field B ≪ B∗.

Researchers report microCT scan of a mouse embryo at unprecedented resolution

first_img Explore further Tomographic imaging of a 14.5-dpc mouse embryo. (A–D) Single X-ray projections (A and B) and sagittal slices from 3D reconstruction (C and D). A and C were acquired with the laser-betatron source and B and D with a commercial microfocus scanner. Credit: Proceedings of the National Academy of Sciences https://doi.org/10.1073/pnas.1802314115 The advent of micro-CT was like the sudden acquisition of a superpower, allowing researchers to image the insides of objects and organisms noninvasively for the first time. The information gathered by micro-CT systems is compiled into slice-by-slice information, providing a look at any cross-section of a sample.Basically, the technology is an advanced X-ray transmission technique. A generator emits X-rays that travel through a sample and hit a detector on the opposite side. The sample is rotated and imaged by a fraction of degree repeatedly through 180 or 360 degrees, resulting in a complete 3-D radiograph. Researchers are constantly seeking to reduce acquisition times while increasing resolution in order to acquire imagery of in vivo processes that current technology is too slow to capture. An international collaborative of engineers and researchers now reports on the development of a laboratory-scale micro-CT system using a compact laser-plasma-based X-ray light source, which they used to scan a mouse embryo, a centimeter-scale target, at high resolution. They have reported their results in the Proceedings of the National Academy of Sciences.Plasma acceleration is a technique for accelerating charged particles using high-gradient plasma structures. In this case, the radiation was generated by the betatron motion of electrons inside a dilute, transient plasma, which overcame the limitations of previous micro-CT radiation sources using conventional solid or liquid anodes. “We show that with the laser-betatron source, we obtain embryo images of quality equivalent to that of the benchtop scanner but with a single laser pulse rather than the multi-second exposure required with the X-ray tube,” the authors write.They report that their device has a higher photon energy than that used to demonstrate phase-contrast tomography of insect samples. They have increased the X-ray penetration depth and improved the signal-to-noise ratio, resulting in images of higher quality than those produced by commercial microfocus scanners.Producing such high-resolution, submicrometer-level details has been a major objective in micro-CT development, but the researchers emphasize that they’ll need to continue refining their technology before it’s ready for commercial production. One drawback is a lower X-ray to optical conversion efficiency, resulting in the necessity for multiple-shot exposures and longer scan times. Because of the low laser repetition rate, their scan of the mouse embryo took several hours. “This can be resolved by upgrading the laser system driving the accelerator,” they write. But they believe their technique will result in compact X-ray sources for rapid imaging of soft biological samples with unprecedented resolution. This document is subject to copyright.

Proceedings of the National Academy of Sciences doi.org/10.1073/pnas.1802314115AbstractIn the field of X-ray microcomputed tomography (μCT) there is a growing need to reduce acquisition times at high spatial resolution (approximate micrometers) to facilitate in vivo and high-throughput operations. The state of the art represented by synchrotron light sources is not practical for certain applications, and therefore the development of high-brightness laboratory-scale sources is crucial. We present here imaging of a fixed embryonic mouse sample using a compact laser–plasma-based X-ray light source and compare the results to images obtained using a commercial X-ray μCT scanner. The radiation is generated by the betatron motion of electrons inside a dilute and transient plasma, which circumvents the flux limitations imposed by the solid or liquid anodes used in conventional electron-impact X-ray tubes. This X-ray source is pulsed (duration <30 fs), bright (>1010 photons per pulse), small (diameter <1 μm), and has a critical energy >15 keV. Stable X-ray performance enabled tomographic imaging of equivalent quality to that of the μCT scanner, an important confirmation of the suitability of the laser-driven source for applications. The X-ray flux achievable with this approach scales with the laser repetition rate without compromising the source size, which will allow the recording of high-resolution μCT scans in minutes.center_img Journal information: Proceedings of the National Academy of Sciences Could a particle accelerator using laser-driven implosion become a reality? © 2018 Medical Xpress One of the most vital research paths in genetics is the relationship between genes and embryonic growth. Noninvasive, whole-body 3-D imaging of embryos is highly important for establishing these relationships in order to determine the impact of specific genes on development.

HIDCO measuring steps for plantation programme to focus on avenue plantation on

first_imgKolkata: West Bengal Housing and Infrastructure Development Corporation (HIDCO) is taking a planned approach in its new plantation programme, that will start soon with a focus on avenue plantation on all major roads.”We had thought of this plantation much earlier. However, construction work for the Airport-Garia Metro project was going on in a number of stretches. Work is still on in the station area, however, a number of stretches have been opened for traffic, as per original road alignment. We would be planting trees at these places,” a senior HIDCO official said. Also Read – Heavy rain hits traffic, flightsIt has been decided that trees for this plantation will be sourced mostly from the Tall Tree Nursery that has come up on a 5 acre area at Action Area 1D, not far from Tata Medical Centre. It may be mentioned that this nursery is a joint initiative of HIDCO and Forest department’s Wasteland Development Corporation. Quality saplings up to 4-5 feet are available in the nursery.”We would concentrate on slender trees that do not spread out in a canopy when grown, because these would obstruct street lights and vision of drivers. Pine trees, ‘debdaru’, ‘sonajhuri’, Asian Cherry Blossoms, palm trees and coconut trees are on our radar,” the official said. Also Read – Speeding Jaguar crashes into Merc, 2 B’deshi bystanders killedThe species of the trees will be finalised only after consultation with experts. The soil would be tested for suitability. “We want to ensure that the trees we plant have a minimum chance of uprooting, even during squalls. In a recent thunderstorm, when many trees fell down in the city, New Town was also not an exception,” the official maintained.It may be mentioned that for the tea garden at Eco Park, Andrew Yule had sourced earth from their North Bengal tea gardens, as the existing soil was not suitable for tea bushes. There will be a sea change in the plantation strategy adopted by HIDCO. “Earlier, we concentrated on large areas of plantation, whenever space for greening was available. This included broad road medians near Eco Space, near Eco Urban Village and also other planned green areas in all nooks and corners. Now, we will concentrate on replacement of saplings on existing green zones, which have not survived. A survey is being done by the Forest directorate at our request, to find out the extent (10-15% as per preliminary estimate) of replacement necessary. Mending of bamboo fences will also receive a focus,” the official added.Last year, during monsoons, HIDCO had planted 65,000 trees, while 50,000 trees were planted in the year 2016.last_img read more

Clicking pictures may enhance visual memory

first_imgClicking pictures may help recall the details of what you see, say scientists who found that having camera can help enhance visual memory. Researchers, including those from University of Pennsylvania in the US, conducted two experiments. In the first they had 294 participants tour a real-life museum exhibit of Etruscan artefacts.As the participants toured the exhibit, they listened to an accompanying audio guide. At the end of the tour, they answered multiple-choice questions asking them to identify objects they had seen or complete factual statements from the audio guide. The results showed that those who took photos visually recognised more of the objects compared with those who did not have a camera. However, they also remembered less auditory information than their camera-less peers.

Participants navigated through the gallery on screen as they would in real life and some were able to take pictures of what they saw on screen by clicking an on-screen button.Again, participants who were able to take pictures were better at recognising what they saw and worse at remembering what they heard, compared to those who could not take pictures. Researchers found that participants who were able to take pictures performed better on visual memory tasks regardless of whether the objects in question were the most or least photographed.

These findings suggest that having a camera changes how people approach an experience in a fundamental way, researchers said. “Even when people don’t take a photo of a particular object, like a sculpture, but have a camera with them and the intention to take photos, they remember that sculpture better than people who did not have a camera with them,” researchers said.last_img read more

User ratings for medical apps may be misleading

first_imgHigh “star rating” of medical apps does not necessarily reflect accuracy or value, say scientists who warn users to not trust such platforms just based on reviewsResearchers from Johns Hopkins University in the US screened 250 user reviews and comments for a once popular – but proven inaccurate – mobile app that claims to change your smartphone into a blood pressure monitor.”People tend to trust user reviews when shopping online and use them to decide which products to purchase, but that doesn’t cut it for medical apps,” said Timothy Plante, a former fellow at the Johns Hopkins. Also Read – Add new books to your shelf”There are certain thresholds of accuracy that need to be maintained, and a five-star rating doesn’t replace clinical validation studies and FDA review,” said Plante, who is now an assistant professor at the University of Vermont in the US.The researchers said that unregulated mobile health app use could give people a false sense of security, which could lead to dire health consequences.In the study, published in the Journal of the American Medical Informatics Association, the physicians call for medical professionals to be more sceptical of apps that do not have scientific studies backing them. Also Read – Over 2 hours screen time daily will make your kids impulsiveThe researchers analysed 261 user ratings and reviews from the app store before the it was taken off the market for reasons that were not made public.The average star rating of the latest version of the app was four out of five stars, and 59 per cent of the reviews assigned the app five stars. Commentary praising the accuracy of the app based on anecdotal experience comprised 42 per cent of the reviews, and 10 per cent of the reviews mention inaccuracy. Yet, 24 reviews – 10 per cent – claimed to use the app for medical purposes, with 11 people using it to manage their high blood pressure treatments, one person using it to manage kidney disease and another person using it to monitor blood pressure after a heart transplant.”The data showed that disclaimers aren’t a complete solution. Consumers will continue to use these devices to manage their health care, which could be dangerous if they are substituting the app for medical care with a professional,” said Seth Martin, assistant professor at the Johns Hopkins University.last_img read more
