Solar Plane to Fly Continuously Around Mars

first_imgSky-Sailor, the working dream of a solar-powered, autonomously-controlled microairplane, has exciting implications in two areas: one on the technological advances of unmanned air vehicles (UAVs); and another on exploring the lower atmosphere of Mars. Scientists André Noth, Walter Engel and Roland Siegwart of the Institute of Robotics and Intelligent Systems in Switzerland believe that Sky-Sailor will reach the inner orbit of Mars within a decade or two, depending on advancements in technology. Components of Sky-Sailor. Image credit: Noth, et al. Engineer André Noth with Sky-Sailor. Image credit: Alain Herzog – EPFL. While other solar airplanes have been developed since the late 1970s, the scientists have defined loftier goals for Sky-Sailor. The group plans to have the airplane fly continuously for at least several months, all by itself, and all on solar power.“Sky-Sailor is unique because it is designed to fly autonomously—not only during the day, but also during the entire night until the next morning, where a new cycle of charge and discharge of the battery can start,” Noth explained to The project began in late 2003 as part of a technology program for the European Space Agency to explore the gap between the areas covered by high-flying orbiters and land-rolling rovers. By early 2005, the scientists had built and tested an initial prototype, which was launched by hand and achieved a continuous flight time of five hours, with a 24-hour flight test planned for the summer of 2007. In a paper in IEEE Robotics and Automation Magazine, Noth, Engel and Siegwart reported on their most recent research.“The benefit of having a solar airplane on Mars would be the ability to cover an extended area in a short period of time and on each location on the red planet,” Noth said. “Rovers have poor area coverage and satellites a predefined path, i.e. their orbit. Airplanes could be a complementary help for ground mission, giving information to a rover about the best path to reach a point of interest, and avoiding stones and ravines where it could get stuck. Moreover, an airplane could study the atmosphere (e.g. composition, winds, weather) and the magnetic field, which are topics which we have very little information on so far.”In order for Sky-Sailor to navigate Mars, the group demonstrates, the plane must satisfy that planet’s flight conditions: a low atmospheric density, decreased solar energy, variable winds and below-freezing temperatures. At an altitude of 1500 m and an average velocity of 30 km/hr, Sky-Sailor’s top priorities include a low-weight structure to minimize energy needs, and a small enough volume to fit inside the shell which will transport the plane to Mars. According to these constraints, the scientists demonstrate an optimal wingspan of about 3 m. Weight is a bit trickier, especially with the current battery densities which mean the batteries currently account for almost half of the plane’s total mass of 2.6 kg. The scientists’ goals, therefore, rely on improved battery technology in the future.“Sky-Sailor was designed as a prototype flying on Earth to prove that continuous flight is feasible on Mars (by flying at altitude were air density is comparable, for example),” Noth explained. “In fact, many challenges remain, such as the fact that, at the very low temperature on Mars, the battery would have a highly reduced capacity if not heated and maintained at more than 0-10°C. Moreover, entry into the atmosphere of the red planet with the airplane folded in a shell would decelerate with the use of a parachute, which requires investigation. So whereas it is feasible now on Earth, it would require a huge amount of additional work to be sure that the airplane can safely travel all the distance to Mars, withstand the vibration during the entry in the Martian atmosphere, then deploy itself and work in an atmosphere where the temperature can decrease to -100°C.”The current plane prototype, which the scientists constructed by hand, is made of rigid, low-weight materials including balsa wood and carbon fiber. The 216 flexible solar cells, with a 17% efficiency, enable the plane to retrieve more than 80 watts at optimal sun conditions. To maintain a leveled flight, Sky-Sailor requires around 16.25 watts—the excess energy is stored in a lithium-ion polymer battery for night use. With the storage capability, the scientists say that the plane can fly all night, plus several more hours during cloudy or foggy conditions.For such a small, light-weight structure, the plane can do some high-tech things. Digital sensors can measure altitude and airspeed, allowing the plane to fly over targets such as coasts or canyons, while a CCD camera can image the ground. While the plane’s default is autopilot, a ground control station can also allow the scientists to monitor and give orders to the plane while in flight.Based on these abilities, the group suggests that Sky-Sailor might have uses closer to home, as well. Because of its low-cost, long flight times and simplicity, the scientists list applications such as border surveillance, weather research, media imaging, and forest fire prevention—where the latter alone costs billions of dollars in damage each year.“What is the most exciting is the global design methodology of such a system,” said Noth. “In fact, we are not developing new solar cells or new batteries for the prototype, but rather we are finding the best way to combine actual technologies in order to optimize characteristics like the autonomy, for example. For comparison, a good chef can cook you an exceptional meal with standard products, whereas an apprentice can miss it completely even using expensive products. The important knowledge lies in the recipe, and this is the same for the case of an engineer working on a multidisciplinary project.”Citation: Noth, André, Engel, Walter, Siegwart, Roland. “Flying Solo and Solar to Mars: Global Design of a Solar Autonomous Airplane for Sustainable Flight.” IEEE Robotics & Automation Magazine.

Theoretically, quantum dot displays could provide extremely high-resolution images and higher energy efficiencies than current TVs.

The researchers, Tae-Ho Kim and coauthors from various institutes in South Korea, have published their study on the first four-inch, full-color quantum dot display in a recent issue of Nature Photonics. The display consists of a film printed with trillions of the tiny quantum dots (an average of 3 trillion per cm2). The quantum dots emit light at a specific wavelength (color) that can be tuned by changing the size of the quantum dots. Previous attempts to make full-color quantum dot displays have faced challenges in that image quality tended to decrease with the size of the display. To overcome this challenge, the researchers in the current study used a different method for applying the quantum dots to the film’s surface. Instead of spraying the quantum dots onto the film, the researchers created an “ink stamp” out of a patterned silicon wafer. They used the stamp to pick up strips of size-selected quantum dots, and then stamp them onto the substrate. Unlike the spraying methods, this method does not require the use of a solvent, which previously reduced color brightness.As the results showed, the new quantum dot display has a greater density and uniformity of quantum dots, as well as a brighter picture and higher energy efficiency than previous quantum dot displays. The new display is also flexible, so applications could include roll-up portable displays or flexible lighting applications. The technology could also be used in photovoltaic devices, which would especially benefit from quantum dots’ high energy efficiency.

NASA satellite could reveal if primordial black holes are dark matter

Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. The scientists, Kim Griest and Agnieszka Cieplak of the University of California, San Diego; Bhuvnesh Jain of the University of Pennsylvania; and Matthew Lehner of the University of Pennsylvania and Academia Sinica in Taipei, Taiwan, have published their study on using the Kepler satellite to detect PBH dark matter in a recent issue of Physical Review Letters.“The nature of the dark matter is one of the biggest unsolved problems in all of science and so an answer would be extraordinary,” Griest told “If it turns out to be primordial black holes, that will be totally fascinating and everyone will want to understand what happened in the early universe to create them. If nothing is found, then we eliminate much of a major contender, but it is not as exciting.”As the scientists explain, PBHs have been considered as a candidate for dark matter since the 1970s. These black holes are thought to have formed during the early universe from density perturbations that may have resulted from a variety of factors, such as inflation, phase transitions, and possibly even the collapse of string loops. Because there is no single theory for how PBHs formed, scientists don’t know how massive they would be. However, previous experimental and theoretical work has eliminated most PBH masses, including almost the entire mass range from 10-18 to 1016 solar masses, the exception being the mass range between 10-13 and 10-7 solar masses. Scientists call these 5 orders of magnitude the “PBH dark matter window.”In the current study, Griest and his coauthors think that Kepler data could potentially rule out a significant portion of this window. Currently, Kepler’s photometer is measuring the light intensity of stars – about 150,000 different stars every 30 minutes. When analyzing the data, scientists look for specific fluctuations in star light, or stellar flux, since a decrease could signal an Earth-sized planet transiting in front of the star. Explore further In their study, the physicists have shown that Kepler’s photometer could also be used to detect small amounts of gravitational lensing, or “microlensing,” which is the bending of star light as it travels through nearby space. According to general relativity, the bending is due to the gravity of an invisible mass that acts like a “lens” and lies between the light source (star) and observer (satellite). This lens could be a PBH or another type of massive compact halo object (MACHO) as well as mini halos, all of which are dark matter candidates.“PBHs are really just one form of MACHOs,” Griest explained. “In the mass range we are sensitive to, I think PBHs are the most likely MACHO, but we won’t really be able to tell if they were instead, say, non-topological soliton objects, which are another form of MACHO.”According to the scientists’ calculations, Kepler could detect microlensing events caused by masses in the range between 5 x 10-10 and 10-4 solar masses, which means it could potentially rule out about 40% of the mass in the PBH dark matter window, if it doesn’t detect anything. If it does detect microlensing events, then of course the implications would be much more exciting: PBHs could be dark matter.“One never really expects to solve such a major problem that has defeated explanation for more than 50 years,” Griest said. “So my skeptical scientist side says, most likely we’ll rule out some parameter space. The searches for particle dark matter at LHC, etc., have so far come up empty handed, so I do think PBHs are becoming more likely as candidates.”Although other microlensing surveys have examined tens of millions of stars over periods of many years, the scientists explain that Kepler can, somewhat surprisingly, provide stronger limits on dark matter in this particular mass range than these earlier surveys. Kepler’s advantages arise from the extreme precision of its photometer, which allows very small magnifications to be detected.Griest and his coauthors have already begun looking at Kepler’s data, which is publicly available. Analyzing the data will not be that simple, since it requires an understanding of the complex light curve data, understanding false positives and background events (such as stellar flares), and using strict selection criteria. Could primordial black holes be dark matter? ( — The primary objective of NASA’s Kepler satellite, which was launched in March 2009 to orbit the Sun, is to search for Earth-like planets in a portion of the Milky Way galaxy. But now a team of physicists has proposed that Kepler could have a second appealing purpose: to either detect or rule out primordial black holes (PBHs) of a certain mass range as the primary constituent of dark matter.

Study shows lower ozone pollution in Sao Paulo when drivers switched from

first_img( —A study conducted by Alberto Salvo and Franz Geiger of the National University of Singapore and Northwestern University respectively, has revealed that when drivers switch from using ethanol to power their vehicles, to gasoline, ozone levels in the local atmosphere may drop. They offer details of their study in their paper published in the journal Nature Geoscience. Sasha Madronich of the U.S. National Center for Atmospheric Research offers a News & Views perspective on the duos work in the same journal issue. Explore further Ethanol—fuel derived mainly from plants—has been touted for several years as a much cleaner alternative to gasoline. When burned, ethanol doesn’t emit as much particulates or carbon monoxide, and more importantly perhaps, hydrocarbons such as CO2. But now it turns out, it may have a previously unknown downside as Salvo and Geiger have discovered burning ethanol in cars can cause higher levels of ozone to come about in the local atmosphere than does burning regular gasoline.Ozone comes about in the atmosphere due to interactions between volatile organic materials along with nitrogen oxides and sunlight. Combustion engines don’t produce ozone, but their emissions can lead to other interactions that do, thus it’s far more difficult to determine what impact vehicular traffic has in the generation of ozone, than it is to measure other pollutants such as carbon monoxide.This latest study actually came about partly by accident—the cost to consumers of ethanol began rising in São Paulo to the point that drivers soon began turning back to gasoline (Brazil is major producer of sugar cane produced ethanol). Coincidently, the city also maintains air pollution monitors throughout the area. To learn of the change in air quality, the researchers simply analyzed air pollution levels for the years 2009 through 2011—a period of steep price increases for ethanol. They were surprised to learn that moving back to gasoline, which did result in higher levels of carbon monoxide and nitrogen oxides along with hydrocarbons, also caused lower levels of ozone. They suggest this happens because ozone chemistry in São Paulo is restrained by high concentrations of nitrogen oxides and also the limited availability of volatile organic compounds. Thus, it appears the phenomenon they observed, might be unique to the area.Madronich isn’t as sure, suggesting that the results of the study in Brazil might be applicable in other places and perhaps should even serve as a “gold standard” for studying the impact of different types of fuel used in vehicles on air pollution. Prior studies she notes, have been limited to the lab, or by a lack of real world opportunities. Centro de São Paulo, Brasil.

However, the predicted effect of various gasoline/ethanol blends on the concentration of atmospheric pollutants such as ozone varies between model and laboratory studies, including those that seek to simulate the same environmental conditions. Here, we report the consequences of a real-world shift in fuel use in the subtropical megacity of São Paulo, Brazil, brought on by large-scale fluctuations in the price of ethanol relative to gasoline between 2009 and 2011. We use highly spatially and temporally resolved observations of road traffic levels, meteorology and pollutant concentrations, together with a consumer demand model, to show that ambient ozone concentrations fell by about 20% as the share of bi-fuel vehicles burning gasoline rose from 14 to 76%. In contrast, nitric oxide and carbon monoxide concentrations increased. We caution that although gasoline use seems to lower ozone levels in the São Paulo metropolitan area relative to ethanol use, strategies to reduce ozone pollution require knowledge of the local chemistry and consideration of other pollutants, particularly fine particles.Press release © 2014 Journal information: Nature Geoscience Citation: Study shows lower ozone pollution in Sao Paulo when drivers switched from ethanol to gasoline (2014, April 28) retrieved 18 August 2019 from read more

Study shows winning causes people to be more likely to cheat the

first_imgCredit: George Hodan/ public domain Common sense might suggest that if one person beats another in a competition, they would be less likely to cheat on a second go round—but the study conducted by the pair in Israel suggests the opposite is true, and that the reason is likely because winners experience a sense of entitlement.One of the experiments began with the researchers asking 86 volunteer college students to pair up and compete against one another in an estimation game—each was shown a certain number of objects on a computer screen for just two and a half seconds, not enough time to count them. The volunteers were then asked to make an estimate on how many had been there and were told that whichever of the two volunteers was closest to the right number would win a prize.That experiment was followed by another where the same volunteers were asked to play a dice and cups game and were told that they would receive a monetary payment that matched the combined numbers on the dice. In this scenario, the payoff was fixed, which meant that only a certain amount of money would be doled out to the two participants. Also, the volunteers were allowed to report their numbers, thus making it easy for them to lie. In looking at the results, the researchers found that those people that won in the first experiment were more likely to lie in the second, which meant they essentially cheated their opponent out of cash winnings.The researchers also ran identical experiments with the exception that both of the players thought the outcome was random in the first part, thus no one actually beat the other. The people who wound up with more money in those experiments did not cheat more than the losers when the second stage was run.To better understand why people might cheat after winning, the researchers conducted a survey asking participants to imagine a winning scenario and then to put down a number describing their feeling of entitlement—those peopled scored 16 percent higher in how entitled they felt compared to those that thought of something else. This, the researchers suggest, explains the results of their earlier experiments—winners felt more entitled to winnings and thus were more willing to cheat to win. More information: Amos Schurr et al. Winning a competition predicts dishonest behavior, Proceedings of the National Academy of Sciences (2016). DOI: 10.1073/pnas.1515102113AbstractWinning a competition engenders subsequent unrelated unethical behavior. Five studies reveal that after a competition has taken place winners behave more dishonestly than competition losers. Studies 1 and 2 demonstrate that winning a competition increases the likelihood of winners to steal money from their counterparts in a subsequent unrelated task. Studies 3a and 3b demonstrate that the effect holds only when winning means performing better than others (i.e., determined in reference to others) but not when success is determined by chance or in reference to a personal goal. Finally, study 4 demonstrates that a possible mechanism underlying the effect is an enhanced sense of entitlement among competition winners. © 2016 This document is subject to copyright.

Simulation shows nuclear pasta 10 billion times harder to break than steel

first_imgNeutron star. Credit: NASA A better way to model stellar explosions More information: Elasticity of nuclear pasta, Physical Review Letters (2018). … release Explore further Prior research has shown that when stars reach a certain age, they explode and collapse into a mass of neutrons; hence the name neutron star. And because they lose their neutrinos, neutron stars become extremely densely packed. Prior research has also found evidence that suggests the surface of such stars is so dense that the material would be incredibly strong. In this new effort, the researchers report evidence suggesting that the material just below the surface is even stronger.Astrophysicists have theorized that as a neutron star settles into its new configuration, densely packed neutrons are pushed and pulled in different ways, resulting in formation of various shapes below the surface. Many of the theorized shapes take on the names of pasta, because of the similarities. Some have been named gnocchi, for example, others spaghetti or lasagna. Caplan, Schneider and Horowitz wondered about the density of these formations—would they be denser and thus stronger even than material on the crust? To find out, they created some computer simulations.The simulations showed that the nuclear pasta was, indeed, stronger than the material on the crust. The simulations also showed that such formations are likely the strongest material in the entire universe. They showed, for example, that they are 10 billion times stronger than steel. But that is not the end of the story. The simulations also backed up another theory that suggests neutron stars could be generating ripples in the fabric of spacetime due to their strong gravitational pull. The theorized rippling effect is due to the irregular formation of the nuclear pasta. This means that neutron stars could be emitting gravitational waves that could someday be observed by super-sensitive equipment here on Earth. A trio of researchers affiliated with several institutions in the U.S. and Canada has found evidence that suggests nuclear material beneath the surface of neutron stars may be the strongest material in the universe. In their paper published in the journal Physical Review Letters, M. E. Caplan, A. S. Schneider, and C. J. Horowitz describe their neutron star simulation and what it showed.center_img This document is subject to copyright.

Denied justice, insufficient compensation and acceptance in society are just a few to be mentioned.  Stop Acid Attacks is a campaign against acid violence, founded by Alok Dixit. They work as a bridge between survivors and the society. The campaign was brought up, as most of the victims of this brutal crime, have isolated themselves after losing their face. ‘Due to ignorance of the government and civil society, most survivors find no hope and stay like an outcast, in solitude,’ says Dixit. Stop Acid Attack aims to research and track acid attack cases and compile a data to get the actual situation of survivors.In the last two years, Dixit has built a campaign across the country. His organisation, made up mainly of acid attack victims, makes it a point to visit the victims and help them in whatever way possible. It is our hope that more and more such organisations come up to help fellow humans and citizens.

JU Arts students gherao VC senior officials over admission test row

first_imgKolkata: The stalemate over admission tests in Arts subjects at Jadavpur University continued on Tuesday with Vice-Chancellor Suranjan Das and some senior officials of the university remained gheraoed by a section of students of humanities since Monday night.The agitation started off after the university temporarily postponed the admission process of Arts by withdrawing the dates for admission tests that were scheduled to be held from July 3 to 5. Also Read – Heavy rain hits traffic, flightsAn emergency Executive Committee meeting has been called on Wednesday with the aim to resolve the impasse.State Education minister Partha Chatterjee when questioned about such unrest in the varsity said: “These students should decide what they actually want to do.

They do everything other than studies. 99 percent of the institutions abstain from such activities but in a few institutions like these, such things have been continuing.” Also Read – Speeding Jaguar crashes into Merc, 2 B’deshi bystanders killedChatterjee was also critical in respect to the roles played by a section of teachers of the varsity.”Often, the students do not have proper understanding of the situation.
