The Crew-2 booster, which teams refer to as “flight proven,” last flew in November, and its sooty façade bears the markings of its previous journey into space. This is something we pay a lot of attention to.” “I know there’s a little boy out there whose mom is flying. “We ask ourselves all the time, would we be willing to fly our families on these vehicles?” Reed said. But that’s a tiny percentage of the total launch weight, and NASA and SpaceX decided that the overage didn’t pose a threat to the astronauts. During the process, they learned from teams at SpaceX’s Texas facility that the company has been routinely loading extra liquid oxygen fuel into Falcon 9 boosters-the equivalent of 2,500 to 3,000 pounds of fuel, Stich said. But before certifying the rocket and spacecraft for the Crew-2 flight, engineers scrutinized every aspect of the hardware, looking for any defects or surprises. The SpaceX crewed Dragon capsules are designed to fly at least five times each, with some refurbishment between journeys. “This business of human spaceflight is unforgiving,” Norm Knight, NASA’s deputy manager of flight operations, said at a pre-flight press event. That equation changes when humans are involved. SpaceX says that the latest iterations of its Falcon 9 boosters, known as Block 5, are designed to survive at least 10 launches-and Benji Reed, SpaceX’s senior director of human spaceflight programs, says the company intends to push that limit for uncrewed missions. Since then, it has achieved 80 rocket landings, both on land and on barges at sea, although the company’s boosters still occasionally miss their mark.Īmong roughly two dozen reused boosters in the company’s inventory, the most flown is booster B1051, which has so far survived nine uncrewed launches and recoveries. In December 2015, the company successfully returned a Falcon 9 rocket booster to its landing pad for the first time. The concept is not new for years, the space agency reused its small fleet of space shuttles, but reusable rockets weren’t a reality until SpaceX entered the scene. “Flight proven”īoth NASA and SpaceX contend that reusable spacecraft are crucial for making space travel more affordable. “There’s nothing like it, when you look out the window and see a spaceship getting prepared and realize that you’re going to be riding on it in a few days,” McArthur, who was rocking a pair of sparkly silver boots, told reporters after they arrived. Late last week, when the crew arrived at Kennedy Space Center, they were treated to a view of their rocket as their plane descended. More than 200 science experiments are also aboard, including several that will investigate human immune cell function. The four-person crew is made up of NASA’s Shane Kimbrough and Megan McArthur, European Space Agency (ESA) astronaut Thomas Pesquet, and Akihiko Hoshide of the Japan Aerospace and Exploration Agency (JAXA). Now the Crew-2 astronauts-all veteran space flyers-are settling in for their roughly 24-hour cruise to the station, where they’ll live for six months.

Total Run - The Total Run is the horizontal length of a stair stringer. The vertical rise should be not greater than 151 inches (3835 mm) between landings or floor levels. Total Rise - The total rise of a flight of stairs is the vertical rise between the bottom of the first step and the top of the finished landing. It is used to determine the length of 2x12 material required to build the stair stringer. The stringer length is the tip-to-tip length of the cut stringer. In a set of stairs 36 inches wide, there are typically three stringers (one on each end and one in the middle). They are cut from 2x12s or larger material - the uncut portion of the stringer should not be less than 5 inches (127 mm) (see diagrams below). Stringer - The stringer is the structural part of a set of stairs. If you have any questions, please Contact Us. The information below explains the stair calculator results in more detail and provides related **building code information. Stair Calculator Results and related Building Codes** Consider all of the possibilities and think them through, before cutting your first stringer. The top tread would either have a gap on the back side of the tread, or the nose of the tread would not have the same overhang as the other treads. Using the diagram below, picture the top step without the last riser installed. Depending on your design, you may need to adjust the depth of your stringer's top step.įor example, if you are not planning to add a riser to the last rise, up to your deck or landing, you may want to subtract the thickness of one riser from the calculated Tread Depth on the top step of the stringers. In most cases, a flight of stairs will require solid risers, unless the Total Rise is less than 30 inches (762 mm) OR the typical Step Height is less than 5 1/2 inches (140 mm) (see the Risers section below for related building code requirements).Īdding solid risers to your stairs will not change the results of the Stair Calculator, so long as you properly attach the risers before you add the treads, as shown in the Stairs with Solid Risers and 2x12 Treads diagram below.īefore cutting your stringers, double-check all of your measurements, and carefully plan how you are going to attach (or not attach) a solid riser at the upper connection point of your stringer.

We want to celebrate the best in photography!ĥ00px is proud to announce the launch of our first annual Global Photography Awards. Its edges are straight lines which connect the outermost points. The convex hull of points in 2D is the smallest convex polygon that encloses all the points. Polygons: convex hulls The convex hull of a set of points. This is the main reason the number of tests for the polygon algorithm is much higher. 2Īnother issue is that it is harder to account for all cases.Įdge cases can be isolated directly in the mathematics for ellipses, but for polygons it requires actually testing each case. This means operations require looping through all the edges and so are of order $O(n)$ or higher, such as finding the area, the perimeter or whether or not a point lies within the polygon.Ĭompare this to ellipses which are defined by a single equation, so all the previous operations can be found directly via formulas in $O(1)$ time. This method returns an IoU of 0 for any distribution that does not intersect it so we have no information about the third distribution.Īnother difficulty with the polygon method is that polygons are described by $n$ edges. For example, in the following image is distribution 2 or distribution 3 more similar to distribution 1? While further statistical techniques can be applied to mitigate the outlier problem, a fundamental issue is that it does not balance the contributions of means and variance well. It has a time complexity $O(nh)$ for $n$ points and $h$ points on each convex hull.Ĭalculating the intersections once they are found is much faster: $O(h_1 h_2)$.Ī problem with this approach is that outliers can have a dramatic effect: The outlier on the top left greatly reduces the IoU while the outlier on the far right greatly increases it. This gives a value that varies between 0 and 1.įinding the convex hulls is the bottleneck in this algorithm. The widget above allows you to adjust these five variables to create many variants of this distribution.Ī bivariate normal distribution with correlation $\rho$ can be constructed from two normal distributions $Z_1$ and $Z_2$ as follows: The correlation $\rho$ between the $x$ and $y$ direction.The standard deviations $\sigma_x$ and $\sigma_y$ in the $x$ and $y$ directions respectively.The means $\mu_x$ and $\mu_y$ in the $x$ and $y$ directions respectively.This is a very common type of distribution that arises naturally in many different situation thanks to the central limit theorem.Ī bivariate (2D) normal distribution is described by five variables: The data that I was working with was normally distributed. There are many different kinds of 2D distributions. Preliminaries Bivariate normal distributions If one bases the effort solely on LOC, the original polygon method required more than 30× the effort to the Wasserstein metric.Ī more detailed breakdown is available at the end in the Code analysis section.įor those who just want to compare scatter plots the right way, jump to How to compare scatter plots. The above table shows where the code can be viewed, the time complexity and the approximate number lines of code (LOC). Gnimuc/Hungarian.jl, /LiorSinai/AssignmentProblem.jl Instead I provide a high level overview and references are given for further information. There are too many algorithms to go into proper detail for each one. This post is the outcome of that investigation. We also brainstormed using circles and ellipses. How much more difficult was it to do the polygon method? Later in my own capacity I challenged myself to try the other methods. (Users weren’t shown the scores just similar plots.) Thankfully the client was open to my suggestions and we did implement the Wasserstein metric. However the other two points remain valid. I’ve crossed out the third point because the convex hull method can be made fast. The convex hull method would be much slower than the Wasserstein metric.It would take too much development time and this was only one of many tasks.For example, it does not handle outliers well. The statistical properties of the polygon method are not adequate.A comparison of different similarity metrics for 2D scatter plots. In more technical terms, they wanted to find convex hulls of the points and then calculate the areas of intersection between them. They wanted to enclose the points in shapes and then calculate the overlap of those shapes. Unfortunately for me, the client came with a solution in mind already. This is the “statistical distance” in the widget. I was drawn to the Wasserstein metric which is used in the popular Fréchet Inception Distance (FID) in machine learning. ( Source code.)įurthermore, there are standard statistical techniques for this sort of problem. The above is a demo of the problem at hand. It is an unusual request but not unheard of - see this question or this one. A while back I was given an intriguing task: rank scatter plots by similarity. Beale later renamed the imprint to Arkhaven Comics.īeale also runs YouTube channels which, according to The Daily Dot, have jointly more than 49,500 subscribers. The use of this name drew backlash from Ethan Van Sciver and other Comicsgate activists, who variously objected to being associated with white supremacists or to the name being commercialized. In September 2018, Beale announced Comicsgate Comics as a "100% SJW-free" comic book publishing imprint. It has been described by Wired and The Washington Post as a version of Wikipedia targeted to alt-right readers. The site was a fork of the contents of English Wikipedia which could be gradually edited to remove the influence of what Beale described as "the left-wing thought police who administer ". In 2017, Beale launched Infogalactic, an English-language wiki encyclopedia.
The device uses wired or wireless controller. The timing of when these modifications are made is based on how long you hold down a button, or in some cases where they’re not needed so much- also determined by vibration from controllers. The programmers used electrical frequency changes and even the conventional rumble function to make it possible for this modification that can compensate recoil. Technology has advanced so that you don’t need good accuracy anymore. One of the main goals of playing action games is to have quick reflexes.

To be sure, for some Minnesotans, the novelty of Walz may have worn off.Īnd even if you admire Walz’s leadership, he’s governed through some of Minnesota’s worst moments, from police killings to riots and the pandemic. The pitch is that Midwesterners cherish minding their own damned business when it comes to their neighbors’ health care or what they do in their own homes (e.g., smoke pot and read banned books if that’s your thing).Ĭonsider Walz’s appeal at a rally-the-troops dinner like he’s doing in Indiana tonight: He can show them a glimmer of light at the end of the cherry red tunnel, especially if Donald Trump is the Republican nominee. He can also sell Minnesota to America as a refuge from the bonkers - to borrow a word local Republicans are using about Minnesota - politics of red states, which are busy outlawing abortion and gender-affirming care.Ī Walz theme during this national outreach is freedom.

Walz and his team are trying to do a few things: I talked to DFL operatives with ties to Walz about why he’s raising his national profile, and the short answer is that there’s plenty of good reasons to do it, and no real downside. He is raising his national profile, however, and with it, Minnesota’s. Throw in some national media appearances, and an viral drone video of him signing the most significant legislation in memory, and you’ve got a lot of folks in Minnesota politics with raised eyebrows.

The massive blast consists mostly of big green explosions which deal 12-24 damage each. Each green bullet deals 2 damage on contact.ĭeath Phase Upon death, the Throne explodes into multiple small explosions and then one large explosion. In total, it fires 48 large bullets in the general direction of the player and will often repeat this attack, each time changing its direction. Tri-shot phase The Throne fires a triple bullet shot from 2 mounted turrets. Large orbs will break the Throne Statues which spawn Guardians. The large orbs cause 12 damage on contact. Large orbs instantly spawn the small orbs upon hit. Each smaller orb deals 5 damage on contact. The large orbs have a high chance to drop mini ammo/health pickups. This is the main attack of the Throne, and is fired toward the player. Orb Phase The Throne fires 2 large green orbs which, in turn, explode into 7 lines of 4 smaller orbs each. Each statue spawns a Guardian that will try to kill your character. As it comes in contact with the Throne Statue props, it will break them.
