Role of Mobile App Analytics In-App Engagement Why IoT Apps are Eating Device Interfaces sarah perez Related Posts A recent report from Strategy Analytics stated that the Apple iPad lost a good bit of tablet market share to Android-based tablet computers, dropping from 96% to 75% in the fourth quarter. As it turned out, however, the numbers the analysts were basing their findings off of were incorrect.As revealed by Samsung VP Lee Young-hee on the company’s earnings call last Friday (and subsequently reported by The Wall St. Journal), the number of Samsung Galaxy Tab sales were not “2 million,” as the company had touted earlier this year – that was how many devices had been shipped to distributors. According to The WSJ, the full quote from Lee Young-hee is as follows, in responding to an analyst’s question about Galaxy Tab sales:“Well, your question was on sell-in and sell-out*. As you heard, our sell-in was quite aggressive and this first quarterly result was quite, you know, fourth-quarter unit [figure] was around two million. Then, in terms of sell-out, we also believe it was quite smooth. We believe, as the introduction of new device, it was required to have consumers invest in the device. So therefore, even though sell-out wasn’t as fast as we expected, we still believe sell-out was quite OK.”*Sell-in means sales to distributors, while sell-out means sales to customers.iPad Market Share Not Eroding as Fast as Previously Reported The news regarding Galaxy Tab sales is important because this particular Android tablet was supposedly one of the more popular non-iPad devices on the market, given the figures Samsung was happily releasing in previous months. In December 2010, for example, Samsung had announced that Galaxy Tab sales had reached 1 million. In January, they had hit 2 million, Samsung had said. The assumption, of course, was that these were sales to customers since that’s what’s generally reported, not sales to distributors.But Samsung had been fudging the numbers a little. By reporting these “sell-in” figures (sales to distributors) without clarifying that was the case, the manufacturer was making it sound as if the device was far more popular than it actually was.The same scenario holds true for the Windows Phone 7 sales figures also recently announced – in December, Microsoft revealed that its partner handset manufacturers have sold over 1.5 million devices to carriers and retailers. Again, this wasn’t handsets sold to customers, but it was a big number and it sounded good to report. The difference is that in Microsoft’s case, the company was clear about the nature of these sales, while Samsung has been less upfront. The details were only revealed thanks to an analyst pressing the Samsung exec for more information on the earnings call.That’s not to say that these numbers – both Microsoft’s and Samsung’s – don’t have at least some merit. It does mean that there’s industry interest in these new devices, and faith from retailers and distributors that the devices will sell.The numbers don’t tell you anything about market share, though. And that means that the analyst report detailing iPad’s rapidly declining market share has been invalidated. The iPad, for now, is still doing just fine – 7.3 million iPads were sold last quarter, Apple reported in January. And almost 15 million were sold through the first three quarters, the company said. Too Early for Android Tablet vs. iPad Comparisons?Frankly, we think it’s a bit premature to start comparing Android tablet sales to iPad sales, since the tablet-ready of the Android operating system (Android OS 3.0, code-named “Honeycomb”) has not even left beta at this point. Google plans to show off more of Honeycomb’s features this week at a special press event, and will probably provide a solid launch date for Honeycomb at that time. At present, however, the Honeycomb mobile OS is not available on any devices in the retail sector, and therefore, is not in consumers’ hands yet.Until consumers are using the first tablet-optimized version of Android, it’s unfair to position the iPad vs. these newer Android competitors. The version of the Android OS running on the Galaxy Tab, for instance, was not designed for tablets and is likely a factor in the device’s return rate of 16% (compared to the Verizon iPad return rate of 2%).When Honeycomb actually debuts on devices consumers can purchase at their local Best Buy or other retail outlets, it will then be time to reevaluate the tablet OS market share figures.Correction: The WSJ said that it had initially misquoted Samsung. Sales were “smooth,” not “small.” This has been removed from the article.

Comments Now playing: Watch this: TVs Video Games 1:55 The dazzling LG B8 55-inch OLED TV has never been priced this low. Sarah Tew/CNET Cheeps! If you happen to live in the vicinity of White Lake, MI, come on out to the White Lake Township Library tonight at 6:30 p.m. I’ll be there talking about some of my favorite money-saving tips and tricks (including something I’ve never discussed here). Everyone who shows up gets a cool prize, and some folks will win even cooler prizes in a raffle. Hope to see you there!You know me: I’m all about the cheap TVs. I prize low prices over picture quality, especially when the latter is “good enough.”But there’s a whole other category of people (including many of my esteemed CNET colleagues) who lean the other way: They want the best possible image quality, period. Price be damned.Thankfully, it doesn’t always have to be. Today only, and while supplies last, Newegg has the LG B8 55-inch OLED 4K TV for $1,098.88 — the lowest price to date and a savings of at least $400 over other stores. (Amazon and Best Buy are both currently at around $1,600.) Forget damned; more like “damn!”See it at NeweggOne important thing to note: This deal comes from Newegg proper. If the inventory runs out, that link will still work, but you’ll likely end up seeing a slightly different price from a third-party seller. Does that matter? It might. Newegg is an authorized LG dealer. If you buy from an unauthorized dealer, LG may not honor warranty claims.The B8 is, according to CNET’s resident expert, David Katzmaier, “the best high-end value TV.” In other words, even though it was still pretty pricey when he reviewed it, overall image quality was second only to LG’s even-pricier models.It features a super-slim design, four HDMI inputs, built-in Google Assistant and all the other advanced goodies you’d expect.The B8 is super popular with owners, too. It has a 4.6-star average at Amazon and a 4.7 at Best Buy. Now, will I still argue that most folks will be just as happy with, say, a 55-inch TCL Roku TV in the $400 range? Absolutely. But if you want the best, at least here you can get it for a lot less than just a few months ago.Your thoughts? Share your voice Walmart LG Titanfall 2 deal: Just $5!Game time! Titanfall 2 was released in late 2016 to mostly glowing reviews. Price then: $60, the same as pretty much every new videogame release.For a limited time, and while supplies last, Walmart has Titanfall 2 for Xbox One for $5. Yep: Five. Bucks. And that’s for a boxed copy, not a download.See it at WalmartFear not, PS4 owners: Walmart also has Titanfall 2 for PS4 for $7. Regular price on both editions: $20. (That’s also proof-positive that you should never buy a videogame when it’s first released.)See it at WalmartShipping isn’t free unless you hit at least $35 in your shopping cart. If you don’t have more to buy, choose in-store pickup to bypass the shipping charge.This is a seriously good game deal.

The physicists, Anthony Bartolotta, a graduate student at Caltech, and Sebastian Deffner, Physics Professor at the University of Maryland Baltimore County, have written a paper on the Jarzynski equality for quantum field theories that will be published in an upcoming issue of Physical Review X.The work address one of the biggest challenges in fundamental physics, which is to determine how the laws of classical thermodynamics can be extended to the quantum scale. Understanding work and heat flow at the level of subatomic particles would benefit a wide range of areas, from designing nanoscale materials to understanding the evolution of the early universe.As Bartolotta and Deffner explain in their paper, in contrast to the large leaps made in the “microscopic theories” of classical and quantum mechanics during the past century, the development of thermodynamics has been rather stagnant over that time. Although thermodynamics was originally developed to describe the relation between energy and work, the theory traditionally applies only to systems that change infinitely slowly. In 1997, physicist Christopher Jarzynski at the University of Maryland College Park introduced a way to extend thermodynamics to systems in which heat and energy transfer processes occur at any rate. The fluctuation theorems, the most prominent of which is now called the Jarzynski equality, have made it possible to understand the thermodynamics of a wider range of smaller, yet still classical, systems.”Thermodynamics is a phenomenological theory to describe the average behavior of heat and work,” Deffner told Phys.org. “Originally designed to improve big, stinky heat engines, it was not capable of describing small systems and systems that operate far from equilibrium. The Jarzynski equality dramatically broadened the scope of thermodynamics and laid the groundwork for stochastic thermodynamics, which is a new and very active branch of research.” Thermodynamic laws that describe heat and energy are being extended to the quantum scale.

Photograph by Paweł Kadysz Stochastic thermodynamics deals with classical thermodynamic concepts such as work, heat, and entropy, but on the level of fluctuating trajectories of atoms and molecules. This more detailed picture is particularly important for understanding thermodynamics in small-scale systems, which is also the realm of various emerging applications.It wasn’t for another decade, however, until the Jarzynski equality and other fluctuation theorems were extended to the quantum scale, at least up to a point. In 2007, researchers determined how quantum effects modify the usual interpretation of work. However, many questions still remain and overall, the area of quantum stochastic thermodynamics is still incomplete. Against this backdrop, the results of the new study represent a significant advance.”Now, in 2018 we have taken the next big step forward,” Deffner said. “We have generalized stochastic thermodynamics to quantum field theories (QFT). In a certain sense we have extended stochastic thermodynamics to its ultimate range of validity, since QFT is designed to be the most fundamental theory in physics.”One of the keys to the achievement was to develop a completely novel graph theoretic approach, which allowed the researchers to classify and combine the Feynman diagrams used to describe particle behavior in a new way. More specifically, the approach makes it possible to precisely calculate infinite sums of all the possible permutations (or arrangements) of disconnected subdiagrams describing the particle trajectories.”The quantity we were interested in, the work, is different than the quantities usually calculated by particle theorists and thus required a different approach,” Bartolotta said.The physicists expect that the results will allow other scientists to apply the fluctuation theorems to a wide variety of problems at the forefront of physics, such as in particle physics, cosmology, and condensed matter physics. This includes studying things like quantum engines, the thermodynamic properties of graphene, and the quark gluon plasma produced in heavy ion colliders—some of the most extreme conditions found in nature.In the future, the physicists plan to generalize their approach to a wider variety of quantum field theories, which will open up even further possibilities.
