Concerning the ability of the IRIP method to detect sections of the transportation network susceptible to be impacted by surface runoff, the evaluation tests show promising probabilities of detection (73–90%) but also high false alarm ratios (77–92%). The evaluation shows that the susceptibility map of surface runoff accumulation is able to identify the concentrated surface runoff flows and that the susceptibility map of transfer is able to identify areas that are susceptible to soil erosion. Comparison tests are performed using a standard verification method for dichotomous forecasting along with five verification indicators: accuracy, bias, success ratio, probability of detection, and false alarm ratio. The method is applied in the Lézarde catchment (210 km 2, northern France) and the susceptibility maps are evaluated by comparison with two risk regulatory zonings of surface runoff and soil erosion, and two databases of surface runoff impacts on roads and railways. In a second part, the paper focuses on the evaluation of the surface runoff susceptibility maps. The method aims to be simple to implement and robust for any type of study area, with no requirement for calibration or specific input format. The method input data are the topography, the land use and the soil type. The method, called IRIP (Indicator of Intense Pluvial Runoff, French acronym), uses a combination of landscape factors to create three maps representing the susceptibility (1) to generate, (2) to transfer, and (3) to accumulate surface runoff. This paper presents a method to create maps of surface runoff susceptibility. Surface runoff is the hydrological process at the origin of phenomena such as soil erosion, floods out of rivers, mudflows, debris flows and can generate major damage.

Perhaps he is not someone who engages comfortably in physical contact with people he does not know well. Perhaps he doesn’t want to touch the strangers constantly approaching him for photos for mysterious hygiene reasons of his own. As is standard in internet culture, a variety of intense opinions followed from commenters, with many celebrating Reeves for respecting his female fans, and others saying that his choice of pose was directly influenced by #MeToo proof that male celebrities need to engage in this sort of behaviour in order to avoid potential accusations of sexual misconduct and expensive law suits.īoth these interpretations are possible, as is the idea that Reeves, who is enjoying a career high and moment as the universally beloved golden good guy of Hollywood, has always seemed unique and even a little awkward. In the photos, Reeves is doing the usual "arm around the person's waist" celebrity photo pose, but his hand is blatantly hovering behind the women in the photos – he is very deliberately refraining from touching them. I thought about my friend last week when images of actor Keanu Reeves posing with female fans circulated online. I have got used to his physical brand of friendliness, which he expresses the same way with everyone, but I sometimes wonder if someone won’t misread his intent at some point, or just tell him right to his face to keep his hands to himself. His mixed gender siblings are the same, so it appears that this is just how they were raised – he is a hugger, even when meeting friends of friends, and will place his hand on someone’s shoulder (rather than the perfunctory shoulder tap) when politely asking them to let him by on the bus. I have a friend who touches everyone he talks to. However, some people are just more touch-led than others. It should go without saying that the sort of groping physical contact that is the sole remit of career perverts is also deeply unwelcome. The odd arm touch from a colleague I don’t know all that well during a lively conversation is fine, but lingering touches? No. Personally, I don’t like it when strangers put their hands on me. He says, “I like to help.Most of us, female and male, have experience of being touched – not necessarily in a sexual manner – when we would prefer not to be. Today, with his heart wide open and his career going full-throttle, Keanu Reeves remains humble and always ready to reach out to those in need. They collaborated on a book called Ode to Happiness with Keanu writing its text.Įventually, their friendship blossomed into love. They eventually met in person and went on to develop a decade-long friendship. After watching his sister go through so much pain before finally beating leukemia, he now donates seventy percent of his earnings to cancer research.Īlexandra Grant, a Los Angeles-based visual fine artist and philanthropist, heard about a poem Reeves had written.

Weeks later, this tragedy would destroy Reeves’s and Syme’s relationship, so they went their separate ways. But at eight months pregnant, Syme gave birth to their stillborn daughter, Ava Archer. In the late ’90s, Keanu Reeves was in love with actress Jennifer Syme. Hopefully, by setting such a good example, he taught onlookers a thing or two about helping someone in need. When the people sitting at their cafe tables recognized Keanu Reeves, a number of them got up, crossed the street, and helped push the car to the curb so they could rub shoulders with this kindhearted celebrity. He insisted Octavia slip behind the steering wheel while he did the pushing. Octavia started walking toward the trunk, ready to push while Keanu steered.īut Reeves wasn’t about to let that happen. They decided to push the car to the side of the street and out of the traffic. It was Keanu Reeves asking if he could help. Then her night in shining armor appeared on a motorcycle. Not one person got up and offered to help. She could see people seated at cafe tables across the street watching, maybe enjoying her dilemma. She was blocking the flow of traffic, and they were forced to slow down and navigate around her car-but no one stopped for her. On the way home, her car broke down in the middle of the street in a posh area of Beverly Hills.Īs she stood on the side of the street, she was stressed out by a stream of drivers angrily beeping their horns at her.

Fire can also spread so long as there’s debris nearby, which means the whole map might quickly go up if you’re not careful.įuzz testing /KuFdXd3Pl4- Tyler Glaiel January 26, 2022 But grass is flammable, so if you’re attacked with a fire spell, that cat will be set ablaze. On the surface, this all feels pretty typical for the genre, but McMillen and Glaiel are creating something far more complex and variable.Ī simple example: You can send one cat to hide in grass and it’ll increase their dodge chance. At the end of each battle you’ll level up one cat and select a new ability that pairs with their current loadout. You’re managing mana and equipping gear that will give each cat an edge in battle. Each of the cats has different stats and abilities, so one might be great at backstabs with a high movement speed, while another hangs back and casts spells. You start with a squad of four cats with traditional role-playing classes like hunter, mage, and healer (among others). The first part is the tactical combat game, which should feel familiar to anyone who has played Dungeons & Dragons or Into the Breach. It’s easiest to think of Mewgenics in two parts. It’s one of the most ambitious and bizarre strategy games I’ve ever played. But this isn’t just a Fire Emblem knockoff. In early 2020, after several iterations, the team landed on the idea of a turn-based tactical strategy game (with cats), and that’s what stuck. “It’s also not as tight as a brawler,” explains Glaiel, “so you can’t dodge abilities, because you’d have to click the cat and move it out of the way. Not again.”Īfter the brawler idea, the team attempted to make a real-time strategy game (with cats), which Glaiel describes as “too chaotic,” requiring you to keep track of too many things at once. And I didn’t really want to deal with that. As a brawler, it would have to be multiplayer. McMillen and Glaiel never figured out a way to make that work, though: “We knew that we wanted groups of cats,” says Glaiel, “and we couldn’t quite figure out how to work that into the brawler version of the game, because you can’t control four cats. This footage shows what the game might have looked like had it not switched to turn-based combat. Early prototype: When attempting to reboot Mewgenics, McMillen and Glaiel explored the RTS genre. At one point, the new Mewgenics was a Castle Crashers-style side-scrolling brawler (with cats). McMillen is now co-creating the game with Tyler Glaiel - another successful indie developer who last teamed with McMillen on The End Is Nigh - who started working on prototypes for what a new Mewgenics game could look like in 2018. While it’s always been about breeding cats to some extent, this new version of Mewgenics has gone through several iterations. McMillen, meanwhile, retained the rights to The Binding of Isaac, and would later secure the rights to make his own version of Mewgenics. But part of the arrangement handed the rights of Super Meat Boy over to Refenes and his team (who would go on to make Super Meat Boy Forever). In a tweet from earlier this year, McMillen wrote, “I never wanted to cancel Mewgenics way back when, but I had no control over it.” Speaking with Polygon, McMillen was unwilling to go into specifics regarding the split between him and fellow Super Meat Boy developer Tommy Refenes. Mewgenics was even shown at PAX 2013, but, according to McMillen, the project was canceled shortly after that showing. At the time it was being developed as a Team Meat game, and was intended to be the follow-up to the wildly popular Super Meat Boy. Ten years ago, Edmund McMillen, the creator of The Binding of Isaac, announced Mewgenics, a cat-breeding life sim with Pokémon-style combat. I like that the process remains simple either way, but my inner security paranoia does worry about the lack of pin code. If you want to use your Magic Keyboard with your iPad, iPhone, or Apple TV, you still have to pair over Bluetooth. There's a notification confirming the pairing, but you don't even have to acknowledge it. If you buy a Magic Keyboard for a Mac you already own, however, all you have to do is take the Lightning cable it comes with, plug the Lightning end into the keyboard and the USB end into the Mac, and you're paired. If you buy a new Mac that comes with the Magic Keyboard, it'll also come pre-paired. But with the Magic Keyboard, like the other new Magic accessories, Apple has made it even simpler on the Mac. Magic Keyboard Functionalityīluetooth pairing has gotten much simpler. If the MacBook Pro were to get something closer to the Magic Keyboard in terms of stability and feel, I'd be thrilled. That said, I like the direction Apple is going with keyboards. I think that's partly because the MacBook Pro still has the older arrow key layout, so I never really unlearn it. Context is important but all other things being equal, consistency is a user benefit.įor example, I still occasionally trip up on the arrow keys on both the Magic Keyboard and the new MacBook, and for the same reason-the new spacing eliminates tactile awareness. But it does mean I notice whenever I change from one to the other. Right now the Magic Keyboard is somewhere between the MacBook Pro keyboard and the new MacBook Keyboard, which makes sense given the switch. That would be consistent and, frankly, badass. Aesthetically, I'd love for the keys to be black. In fact, I find myself wishing the Magic Keyboard was even more like the MacBook keyboard. Blame the fading memory of the former set against the increasingly popularity of the latter. The Magic Keyboard has moved far from the old typewriter and early personal computer keyboards and now has much more in common with laptop keyboards. Apple won't win over any Extended Keyboard II fans with this design, of course.

For the 1932 season, the park operated only Wednesday through Sunday, and in 1933 it closed. The Wall Street Crash of 1929 took its toll on the park and by 1931 it had gone into foreclosure. A third coaster, Whirlwind Racer, was added in 1928. The original Giant Dip coaster was replaced in 1920 by a new, more thrilling coaster that was twice the size of the Giant and was eventually named Lightning. Under Perkins' ownership, the park continued to prosper and additional amusements were added, including a 300-foot-diameter pool that became known as Lake Takadip. He built the park's first roller coaster, The Giant Dip, in 1912, which proved to be so popular that another coaster, The Greyhound, was added in 1915. Perkins who transformed the park from a picnic grove to an amusement park. The park was purchased in 1911 by Henry J. In the early 1900s, a few mechanical rides and a carousel were added. The Springfield Street Railway extended its line to the park in 1900 and, although Riverside was at the end of the Springfield Street Railway, it was not owned by the railway and is, therefore, not considered a trolley park, contrary to published reports. Prior to 1900, most of the park's patrons arrived via steamship. It was briefly changed to Riverside Grove, and then eventually Riverside Park in 1912. It began as a picnic grove in 1870 named Gallup's Grove. Throughout much of the 20th century, the park was known as Riverside Park. Superman The Ride is among the park's most notable rides, having appeared as a highly ranked roller coaster in the annual Golden Ticket Awards from Amusement Today since the ride opened in 2000. Opening in the late 19th century, it is the oldest amusement park in the Six Flags chain, acquired by Premier Parks in 1996 and rebranded Six Flags New England in 2000.

The blades offer a universal fit, but an adapter may be needed for installation on some models. Affixed to a vented bridge, the Anco 31-Series blade uses the company's exclusive KwikConnect system for easy installation. The blade is made of a proprietary rubber compound, which provides a streak-free wipe with conventional washer fluid on most windshields and is coated in a no-wax solution to prevent degradation. Its 31-Series rubber blade line is a top performer and available at a competitively affordable price compared to other traditional-style wiper blades. Specializing only in the manufacturing of wiper blades and related parts, Anco has been offering premium blades for nearly a century. The blades even stay flush at highway wiper arm speeds, which isn't always the case for other wipers. And because of the spring design, pressure is applied equally across the blades so there's no skips or smearing. Nevertheless, if there's plenty of rain and snow where you live, this Bosch wiper blade works wonders in keeping your windshield clear. There is a catch, however: An adapter (disappointingly not included) is required to make the Bosch blade fit with hook system wipers found on most vehicles, unless they're German luxury cars for which Bosch is considered OEM equipment. And thanks to a double-lock connector, the Bosch Icon beam blade is easy to install on the wiper arm. This set of Bosch rubber blade wipers is also one of the better performing ones compared to more expensive blade competitors.Īccording to Bosch, its Icon wiper blade with ClearMax 365 holds up against cracking up to 40% longer than competitors, which makes it even more appealing to the value-minded shopper. For the purposes of this best windshield wipers list, we've included pricing for 24-inch blades that are common applications among a wide variety of sedans, SUVs and crossovers.Īlthough beam wiper style blades are pretty set in terms of design (rubber blade attached to a concealed bracket frame), the Bosch Icon wiper blade line is one of the cleanest in terms of simplicity and our pick for the best overall windshield wiper blade out there. We've based our recommendations on hands-on experience and customer satisfaction ratings at popular shopping sites. We've compiled a list of the best windshield wipers in a variety of categories based on your budget, type, insert material and how you'll use them. If choosing the best windshield wipers for your needs has suddenly become more complicated than you first thought, don't fret. There are also weather-specific options designed specifically to perform and operate in certain conditions such as ice and snow. While most blades on the market have inserts molded from rubber, silicone examples are also available that are said to offer better durability and performance in the long run. Outside of the different styles, there are other variables to consider when shopping for windshield wiper replacement. There's a lot more to wiper blades than you think. And the attached beam-style blade provides even pressure and contact distribution. An aerodynamic plastic casing conceals portions of the hinge while maintaining openings for debris to pass through. This type of blade features elements from both traditional and beam styles. Although the beam wiper's design applies pressure more evenly, which improves performance, a downside is substances like sand might get clogged due to the wiper assembly's solid shape.
Sometimes this condition can be confirmed from the definition of. The definition requires the positivity of the quadratic form. For example, the matrixĪ sufficient condition for a symmetric matrix to be positive definite is that it has positive diagonal elements and is diagonally dominant, that is, for all. Satisfying these inequalities is not sufficient for positive definiteness. Bhatia's writing style has always been concise, clear, and illuminating.A real matrix is symmetric positive definite if it is symmetric ( is equal to its transpose, ) andīy making particular choices of in this definition we can derive the inequalities There are many beautiful results, useful techniques, and ingenious ideas here. Bhatia presents some important material in several topics related to positive definite matrices including positive linear maps, completely positive maps, matrix means, positive definite functions, and geometry of positive definite matrices. "I believe that every expert in matrix analysis can find something new in this book. There are many wonderful insights in a first-rate exposition of important ideas not easily extracted from other sources. Like the author's distinguished book, Matrix Analysis, it will be a convenient and much-quoted reference source. "This is a monograph for mathematicians interested in an important realm of matrix-analytic ideas. Its exposition is both concise and leisurely at the same time." -Jaspal Singh Aujla, Zentralblatt MATH Readers who admired his Matrix Analysis will no doubt appreciate this latest book of Rajendra Bhatia." -Douglas Farenick, Image Beautifully written and intelligently organised, Positive Definite Matrices is a welcome addition to the literature. "There is no obvious competitor for Bhatia's book, due in part to its focus, but also because it contains some very recent material drawn from research articles. Cobzas, Studia Universitatis Babes-Bolyai, Mathematica The book can be used for graduate courses in linear algebra, or as supplementary material for courses in operator theory, and as a reference book by engineers and researchers working in the applied field of quantum information." -S. "Written by an expert in the area, the book presents in an accessible manner a lot of important results from the realm of positive matrices and of their applications. The numerous exercises and notes at the end of each chapter also make it the ideal textbook for graduate-level courses. Positive Definite Matrices is an informative and useful reference book for mathematicians and other researchers and practitioners. He guides the reader through the differential geometry of the manifold of positive definite matrices, and explains recent work on the geometric mean of several matrices. He examines matrix means and their applications, and shows how to use positive definite functions to derive operator inequalities that he and others proved in recent years. He discusses positive and completely positive linear maps, and presents major theorems with simple and direct proofs. Through detailed explanations and an authoritative and inspiring writing style, Rajendra Bhatia carefully develops general techniques that have wide applications in the study of such matrices.īhatia introduces several key topics in functional analysis, operator theory, harmonic analysis, and differential geometry - all built around the central theme of positive definite matrices. They have theoretical and computational uses across a broad spectrum of disciplines, including calculus, electrical engineering, statistics, physics, numerical analysis, quantum information theory, and geometry. These matrices play the same role in noncommutative analysis as positive real numbers do in classical analysis. This book represents the first synthesis of the considerable body of new research into positive definite matrices. |
