![]() ![]() Is Faster Better? A Study of Video Playback SpeedĪbstract: In this paper, we explore the relationship between video playback speed and student learning outcomes. 2: David Lang, Guanliang Chen, Kathy Mirzaei and Andreas Paepcke. Overall, these findings indicate that the personalized visualizations improved regulation of practice behavior, transfer of learning and changed the bias in relative monitoring accuracy. ![]() Finally, students in the personalized visualizations condition were more likely to under-estimate instead of over-estimate their performance. Learners in the PV condition showed better transfer on learning. This quasi-experimental pre-posttest study finds that learners in the personalized visualization condition improved the regulation of their practice behavior, as indicated by higher accuracy and less complex moment-by-moment learning curves compared to learners in the control group. The personalized visualizations are based on three pillars: grounding in SRL theory, the usage of trace data and the provision of clear actionable recommendations for learners to improve regulation. Our learning path app combines three Personalized Visualizations (PV) that are designed as an external reference to support learners’ internal regulation process. Personalized Visualizations to Promote Young Learners’ SRLĪbstract:This paper describes the design and evaluation of personalized visualizations to support young learners’ Self-Regulated Learning (SRL) in Adaptive Learning Technologies (ALTs). This leads me to believe the QuantLib dategenerationrule.hpp file (they did not include) that ORE is using is a modified version, as the mentioned rules are not inside the latest file.List of accepted papers Full papers 1: Inge Molenaar, Anne Horvers, Rick Dijkstra and Ryan Baker. Same thing for ThirdFriday, MondayAfterThirdFriday and TuesdayAfterThirdFriday, basically everything in that dategeneration.cpp The offline installer for VS2017 Community was failing for me on download so I ended up using this ISO and then adding the C needed features afterwards: Īnyhow on the testsuite the issues seem to be mostly around missing semicolons and then dategeneration.cpp has quite a few calendars that are not members of QuantLib::DateGeneration such as:ĮrrorĜ2039 'ThirdThursday': is not a member of 'QuantLib::DateGeneration' QuantExtTestSuite c:\engine\quantext\test\dategeneration.cppĘ3 If anyone wants to help with this, my repo is here: check the 1st commit there were various issues with the formatting using the code as is posted here on Windows 10, but now it compiles fine. Once the testsuite is done, it should be about ready to merge into QuantLib. ![]() Okay I started the port of QuantExt and resolved the errors on VS2017 Windows 10 with Boost 1.77.0 and QuantLib 1.23, using the Windows 8.1SDK and haven't finished the testsuite. I'll get the changes into my GitHub fork probably in the next week or so, once I get it compiling as a standalone library. But this would be SO MUCH FASTER if someone well versed in C was helping me do it. I suppose I'll see if I broke anything by running the QuantExt testsuite against it once I work through the errors. So some of the functions I'm potentially breaking but keeping a list for those that know C well so they can fix it properly if they need those functions (I personally don't), mostly by commenting out problematic code segment declarations in MSVC 14.1 (Visual Studio 2017 Community), or adding missing include files that have needed definitions imported. I'm attempting to port it over but I am not exactly a C expert. I see there was a session in 2018 where this was discussed, but haven't seen it done yet. I suppose the real question: is it OSR's desire to keep their extensions separate? If they were integrated into QuantLib, along with the test suite, then it would be maintained by QuantLib devs and updates would be automatically done on their side, freeing up the work that OSR devs would have to do with every incremental update of QuantLib. And likely reduce maintenance on the side of the OpenSourceRisk project team. I understand it is the work of the company in support of Open Source Risk, but this would potentially simplify the development ahead for both OSR and QuantLib. I'm just wondering why, I know it's not required by the BSD license, but is there a reason for leaving the QuantExt extensions outside of the QuantLib library itself? If it was pushed to the QuantLib library, there would be many more "eyes" on it from the open source community, and therefore likely more development upon its work.

This way you can spawn less Static Meshes but maintaining good visuals with less performance hit. Tip: I found that if you increase the Scale of the spawned grass, you can decrease Grass Density. Align to Surface: whether Static Meshes align to surface normals of the terrain or they do not (enable it for grass, flowers and rocks but disable it for trees)įor spawning grass Static Mesh, here are my properties I defined:.Random Rotation: Random rotation (enabled) or same rotation (disabled).Scale X, Y and Z Min and Max: size variation of Static Meshes.End Cull Distance: where the Static Meshes stop spawning beyond this distance (set in Unreal Units).Start Cull Distance: where do you want to start culling, only is used if you have PerInstanceFadeAmount node in the Material (I did not used this in the tutorial).Grass Density: amount of Static Meshes spawning.As soon as you assign a Static Mesh to spawn, you will see it on the landscape, on the grass texture layer.If you can't see grass spawning, make sure you have Real-Time enabled (Ctrl + R). I am using the free SM_FieldGrass_01 from Open-World Kite Demo from UE4 Marketplace. Under Grass Mesh, assign a Static Mesh you want to spawn: Click on the Plus icon to create the first element: Back in Content Browser, double click on the Landscape Grass Type to open its properties. Now we need to assign which Static Meshes to spawn. Then back in the Material Editor and with Grass Output Node selected, assign the Landscape Grass Type as Grass Type: In Content Browser, Add New then Foliage and create Landscape Grass Type: For this we need to create Landscape Grass Type actor. Nothing will happen because we have to define which Static Meshes to spawn. Then connect Layer Sample GrassTexture output into the Grass input: In my case I will start with GrassTexture: Parameter name has to be the same name as one of the texture layers in the Layer Blend node. To define which texture layer to spawn Static Meshes on using the Grass Output Node, you have to use LandscapeLayerSample: We have two texture layers GrassTexture and DirtTexture defined using the Layer Blend node: Where do you want to spawn Static Meshes?.But the name can be changed to anything you want. I rarely change this folder location:īack in the Material Editor, Right-Click in empty space and insert LandscapeGrassOutput node:įirst input element will be named Grass by default. UE4 will create a folder with the map name and save Layer Info's into this folder. ![]() When the menu pops up for saving the Layer Info, click OK. Switch to Landscape Mode (Shift + 3 if using UE4.25 or later Shift + 2 if using UE4.24 and earlier):Ĭlick on the Plus icon for each layer and choose Weight Blended Layer (Normal) for both texture layers: To fix this we need to create Landscape Layer Info. Landscape will turn black and this is normal. Select the landscape in perspective viewport or World Outliner and then in Details panel under Landscape Material, assign the Material: With the Material created we can now apply it to the landscape. This one node is connected into UV input for all terrain textures so they all tile the same.Ĭonstant1Vectors is used for Metallic, Specular and Roughness. I am also using Landscape Layer Coords node for controlling texture tiling. ![]() I duplicated the Landscape Layer Blend for Normal Map setup: I also used Landscape Layer Blend node with 2 layers: Quixel Bridge contains a lot of great landscape textures to use. I am using Started Content textures but you can use any terrain texture you want. If you need detailed explanation how to create this, watch the video above and also see this tutorial UE4: Step-by-Step to Your First Landscape Material (2 Texture Paint Layers). It is a 2 texture material with Specular, Roughness and Metallic inputs controlled by Constant1Vectors.Ĭlick on the image to see larger size (opens in a new tab) I also increased the Directional Light Intensity to 5 to make it brighter. I imported the heightmap into UE4 and reduced the Z Scale to 50, creating the smooth field plains. The size of the heightmap is 2017x2017 (2 square km). The terrain heightmap was created in Photoshop using Clouds filter with few adjustments. I have Post Process Volume inserted with the following properties changed: I am using TimeOfDayTemplate available from File > New: I already have a map setup and terrain ready to go. ![]() However, when we export our screens to image files like PNGs, these vectors get “rasterized”, which means they get saved as pixel data. Ordinarily, when we’re working in Figma, we see sharp, vector-based shapes and text no matter how far we zoom in. Related to the pixel grid is “Pixel preview”. To toggle the Pixel grid on and off, hit ⌘ ' (Mac), or Ctrl ' (PC).This becomes visible when you zoom in close to a frame, and allows you to see where elements are sitting in relation to individual pixels. In addition to any other grids you’ve set up within individual frames, you can also turn on the “Pixel grid” for the whole file. You can then make any edits you want to all those elements at the same time. Figma will select all matching layers in the file.Go to the hamburger menu, then Edit, then select the option you want (e.g.Select an element with the property you want to find (e.g.This enables you both to locate those elements and, if desired, to change all of them at once. For example, you could select all elements in a file with the same font. ![]() Select all with same…Īn extremely useful feature in Figma is the ability to select all layers within a file that share some property. Any hidden layer will be displayed in the Layers list as greyed out, and with a little eye icon next to it. To toggle a layer’s visibility on and off, hit ⌘ Shift ⇧ H (Mac), or Ctrl Shift ⇧ H (PC). The show/hide command works in much the same way as lock/unlock, but determines whether an element is visible within a frame. You can also access the Lock/Unlock commands by right-clicking (Mac/PC) or Ctrl-clicking (Mac) on a layer or its name in the Layers list. To unlock an element, make sure it’s selected in the Layers list, and repeat the same keyboard shortcut. ![]() To do this, select any object and hit ⌘ Shift ⇧ L (Mac) or Ctrl Shift ⇧ L (PC). Particularly when you’re working in files with lots of layers, it can be useful to lock some of them to prevent accidental selection and edits. The keyboard shortcut is ⌘ Shift ⇧ V on Mac, or Ctrl Shift ⇧ V on PC. For this, you can use the “Paste over selection” command. This is useful if you need to paste an element into another frame, and ensure it’s in a consistent place.īut sometimes you need to paste an element exactly where the current selection is. Figma’s standard “Paste” command is the equivalent of the “Paste in place” command in Adobe software: when you paste an element, Figma will position it in the same place as the original. This distinction will be familiar to Adobe users.

Two massive feature race wins at Monza and Sochi played a huge part in him taking the championship.Ī 14-point margin to Ilott in P2 was the gap at the end of a thrilling season. Stunning starts, excellent racecraft and strong tyre management allowed him to overhaul his rivals. From rounds 10 to 23, he finished outside the top 6 just once across the feature and sprint races as he took command of the title battle. His main title rivals Ilott and Tsunoda (in the end) scored nine poles between them, earning 20 and 16 points respectively for doing that.ĭespite that, he overcame all the difficulties to take the championship. The 21-year-old's best qualifying position was P3 on two occasions. ![]() Some mistakes, qualifying struggles and bad luck at the start of the season left him 45 points adrift of Callum Ilott after ten races.Īs a team, Prema struggled in general on a Friday and it left Schumacher with a mountain to climb in feature races. It was far from an easy season for Schumacher. Promotion to Formula 2 followed and Schumacher repeated the pattern from his time in the FIA F3 European Championship: 12 th in his first year in F1’s feeder series, followed by championship glory last year. The German was the second season specialist during his time in junior categories.įinishing 12 th in the FIA Formula 3 European Championship in 2017, he became champion the following year as the beat the likes of future F2 rivals Dan Ticktum, Robert Shwartzman and Marcus Armstrong to the title. Mick Schumacher has earned his spot on the grid for 2021 it would be completely wrong to suggest he only got it because of his surname. With the sizeable car performance advantage he has compared to Schumacher and Mazepin, Tsunoda’s got to be the rookie with the most points at the end of 2021. If he did beat Gasly or pushed him very close – and Perez struggles at Red Bull Racing – a 2022 drive for the senior team isn’t out of the question. If he can start to really challenge his French stablemate on a regular basis from France onwards and score points consistently, that’ll be a great maiden season for him. Nonetheless, Tsunoda would be wise to take things steady and learn a lot in pre-season testing and the first few events. Gasly’s renaissance since his demotion back to the junior team means the Japanese driver is certainly facing a tough competitor in the same car during the upcoming season. In 2020, the Frenchman won his maiden Grand Prix and 2021 is going to be his fourth full season in the sport. Tsunoda goes up against Pierre Gasly at AlphaTauri this year. What would be a successful season for him? The 20-year-old also collected the Anthoine Hubert award for his exceptional rookie campaign in Formula 2. He finished 3 rd, just 15 points behind champion and fellow F1 graduate Mick Schumacher and was arguably the driver of the season as Schumacher and Ilott had already completed a season in F2 in 2019. One of the strong points shown by the Japanese driver was his impressive ability to be quite gentle on the tyres in races and it allowed him to gain places in the closing stages.
![]() One thing I appreciate about Modafinil is that I get hungry like normal and will be motivated to eat. Modafinil simply delivers a clear head and loads of motivation you won't feel like dancing and your hands won't shake. One of the major subjective differences is the lack of twitchiness or buzz, after years of taking ADHD medications I'm intimately familiar with the edgy, cracked-out feeling they deliver, indeed I had grown to enjoy it. These findings demonstrate that the alertness-promoting effects of modafinil and d-amphetamine involve distinct EEG activities and do not reside on the same vigilance regulatory processes. There's a common misperception that Modafinil utilizes a similar mechanism of action to ADHD drugs, but a French study of 33 humans found a distinct difference between Modafinil and the amphetamine-powered stimulants: Since they are focus-promoting pharmaceuticals a lot of comparisons get made between Modafinil and popular ADHD medication. As a veteran Modafinil user, Armo is my preferred form but I'll typically split the pill and take a half dose as it is very potent stuff. This would suggest that Armodafinil is the stronger version, at least when it comes to wakefulness. To quote a 2009 study comparing the two:ĭespite similar half-lives, plasma concentrations following armodafinil administration are higher late in the day than those following modafinil administration on a milligram-to-milligram basis. Modafinil is comprised of an R-isomer and an S-isomer whereas Armodafinil is just the R-isomer. For those who wish to stay on the right side of the law without bothering a doctor for a prescription, Adrafinil is the clear choice. Although Modafinil can be acquired via numerous sources online, varying from shady silk road wannabes to more credible supplement retailers, there's still a legality issue for US citizens. The biggest difference between the two is that Adrafinil is, currently, unregulated in the United States. Adrafinil is technically a prodrug of Modafinil, meaning that it converts or metabolizes into Modafinil in the liver. Adrafinil vs ModafinilĪdrafinil is the non-prescription version of Modafinil and a search for it on Pubmed yields +25 results. Modafinil is an effective and safe medication in the treatment of. The sleep diaries showed increases in feeling refreshed in the morning the diurnal diaries showed significant improvement of performance and of exhaustion. To quote a 2014 randomized, double-blind, placebo-controlled study done by the Department of Neurology in Marburg, Germany: Modafinil is a hardcore wakefulness hack. The French air force includes them in the ejection seat survival packages of fighter jets. In a 2004 study of 10 F-117 pilots, Modafinil attenuated flight performance for up to 37 hours of continuous wakefulness. Army Aeromedical Research Laboratory found that Modafinil was a veritable solution for maintaining acceptable levels of mood and performance during sleep deprivation in periods of sustained wakefulness for up to 40 hours. Launched in the US as Provigil in 1998, it's a relatively younger smart drug.Ī 2012 study of 18 helicopter pilots by the Warfighter Health Division of U.S. Officially a wakefulness-promoting drug, Modafinil is FDA approved for treating narcolepsy and shift work sleep disorder, and in many countries, a prescription is required. With almost 200 human clinical studies in the past 10 years, Modafinil is one of the most studied and renowned pharmaceutical smart drugs on the market. I would describe it as being very much like Adderall, but without the speediness."
