Icon avatars are created by passing an icon as children. The best practice is to pass the property theme to every component. Avatars are found throughout material design with uses in everything from tables to dialog. The properties theme, component and twoToneColor were added in 3.9.0. While you wait, you can use webpack plugin from the community to chunk the icon file. Launch GIMP and open your downloaded template file. ⚠️ Given the extra bundle size caused by all SVG icons imported in 3.9.0, we will provide a new API to allow developers to import icons as needed, you can track #12011 for updates. Prepare your photos: the movie picture or poster you want to make icon must be in 512x512 pixels in size, well, at least width must be 512 pixels and height is 320 pixels, cut, trim and resize into something like that 512w by 320h+ (i usually go 512w x 400h so i can shift around and trim) 2.

Timer Hack – improves FPS significantly.Under these settings, just check following two options: Just like performance settings, these settings play a very important role when it comes to smooth, and stable performance. Since we already setup with 2X rendering resolution, there is no need of using Textures scaling and filtering. Try to make your own settings by keeping on or off these settings. Let Retain changed textures (sometimes slower) unchecked while keeping Disable slower effects(speedup) and Hardware Tessellation(experimental) checked. Chose Display Resolution as mentioned in the above image.įurther, make sure to check Mipmapping, Hardward transform, Software skinning, Vertex Cache and Lazy texture caching (speedup). That should bring performance to its peak. Note: If your device is kind of low-specs or if you see low performance, then go for 1x Rendering resolution. It brings impressive graphics and supports stable gameplay too. If your device is powerful like OnePlus 3, equivalent or even more powerful (Galaxy Series), than high rendering resolution will work. We had many trails, and tests to bring these settings. Changes to these settings affect performance directly. Here comes the most important aspect that gonna boost the entire performance of PPSSPP Emulator. Next, enable the Immersive mode to get full-screen display. However to make graphics more smoother, one can choose “ Bloom” under Postprocessing shader (it may affect performance). We’ve seen good improvement in FPS using it on OnePlus 5, and hope that it will work on other devices as wel. Instead of keeping it off, or selecting any other shader, choose Vignette. We got little more deeper, and found a shader that improves the performance little bit more, instead of keeping it off as we did before. For better performance, we keep Postprocessing shader Off. There you several options to configure PPSSPP’s graphics appropriately. Check the Prevent FPS from exceeding 60 and put 0 values in alternative sped (in %, 0=unlimited). There are two more settings under this panel. That helps to ensure a smooth gaming experience. Keep off the Frameskipping option, and un-check the Auto frameskip. This should bring major performance spike in your PPSSPP gameplay. You just need to select Vulkan under Backend. So, going forward, we don’t have choose between such choices. It works for both, high-end, and low-end devices. The graphics rendering now supports Vulkan that works very fast, and smooth compare other reset of the shaders. Update 07-1-2018: There has been major change implemented in this emulator few days back. If you’ve a powerful handset such as OnePlus 3, Samsung Galaxy S6, 7 or 8 or somewhat like them, buffered rendering shall do wonderful work for you. Under Rendering mode, Tap on Mode and select buffered rendering. Since, the performance varies from device to device, it would be a good try out some changes on your own. In this section we cover some major settings that should bring good graphics, and smooth performance. In the past, we had a great time with Motorola phone, and now we’ve tested this emulator on OnePlus 3 in order to bring these updated settings.īelow is the Best setting For PPSSPP Android, I’ve figured out with so many attempts, testing, and experiments to achieve high FPS as possible, I hope it will work for you as well.īest setting For PPSSPP Android 1# Graphics Just tuning the few options in PPSSPP, you’d be able to get the maximum performance to play games more smoothly and less lags, however, the performance of PPSSPP is entirely depends upon the power of the device, Motorola G is good enough to play most of the games and over the PPSSPP, it is giving an awesome performance. We’ve recompiled these settings, and re-published this tutorial. After being familiar with PPSSPP emulator, I tried multiple settings and tested over many games such DBZ series, GOW, some racing games, Final Fantasy, etc., and finally came up with settings which actually work not only to increase FPS but they also bring good graphic quality as well. However, at initial, it was a bit difficult to play it on my mobile because of low FPS and graphic glitches. We will help you with best settings for PPSSPP emulator for better performance and highest FPS. I’ve completed both the PlayStation 2 parts and already completed its PSP based version, God of War: Chains of Olympus, and the Ghost of Sparta on my Moto G Android phone (earlier) and on OnePlus 3. Since ever I’ve grown up, I always used to be a big fan of action-adventure video games and my most favorite series were God of War. Hello to all readers and of course games lovers. Here is the list of Best Setting for PPSSPP Android. Android Device Compatibility Best setting For PPSSPP Android – Highest FPS, Tested with God of War and more! Open your elf launching method and run off an elf on your internal hard drive. Remember you needed the PS 2 to be modded to run the elf files Enter the flash drive into your system and copy the BIOS DUMP folder to the USB flash drive. After the extraction, you will see a folder open, and there will be a couple of files. Once you get your hands on it, extract it. Today we will discuss th e elf files, so simply go and get the file in your system. Surprisingly you will also find the ISO version of it. Scroll down till you reach the Get PCSX2 section and then go down to the tools, and here you will find the BIOS Dumper. Method 2: From Bios Dumper Bios Dumper BIOSįirstly, you must go to. Thus, we recommend you get the BIOS file (SCPH39001) instead of the Japanese version. They will run the game, but there are some disadvantages. Many people will not suggest using the first Japanese version of the Best PS2 Bios (SCPH10000) as it will somehow affect the compatibility. When you move towards the URL we will share below, you will quickly notice that there are two possible Best PS2 Bios available on the platform, and they are as follows: Thus, getting the correct PS2 BIOS is not a tedious task. PCSX2 Simulator will not include the region locking. But those ROMs will not be able to PCSX2 to run as it requires Best PS2 Bios in many boot games. Let us consider you have the information about the ins and outs on the internet, and you will also agree that getting PS2 games are more straightforward. How to Get Best PS2 Bios or PCSX2 Bios ? Method 1: From Emurom Emurom PS2 Bios For instance, video cards require a faster rate of data flow to be effective. But in some examples, the BIOS and be used and arranged for data travel directly from the devices to the memory. Hypothetically the BIOS is always the mediator between the microprocessor and the Input/output device control information and the data flow. The primary purpose of Best PS2 Bios is to behave as a middleman between the Operating Systems (OSes) and the hardware on which they run. It also can manage the data flow which is taking place between the Operating System (OS) of the system and the connected devices, for example, the hard disk, video adapter, keyboard, video adapter, keyboard, mouse, and printer. Basically, it is an application, and the system’s microprocessor utilizes it to begin the system when you power it on. BIOS is a popular term that is used for the primary input and output system.

The majority of volcanic arcs can be found in the Ring of Fire, a horseshoe-shaped string of about 425 volcanoes that edges the Pacific Ocean. Over millions of years, the rising magma can create a series of volcanoes known as a volcanic arc. As the denser plate edge moves downward, the pressure and temperature surrounding it increases, which causes changes to the plate that melt the mantle above, and the melted rock rises through the plate, sometimes reaching its surface as part of a volcano. These subduction zones can create deep trenches. Oftentimes, this collision forces the denser plate edge to subduct, or sink beneath the plate edge that is less dense. Along this divergent plate boundary are volcanoes such as Mount Nyiragongo, in the Democratic Republic of Congo, and Mount Kilimanjaro, in Kenya.Īt a convergent plate boundary, tectonic plates move toward one another and collide. Along the Horn of Africa, the African plate is tearing itself into what is sometimes called the Nubian plate (to the west, including most of the current African plate) and the Somali plate (to the east, including the Horn of Africa and the western Indian Ocean). The East African Rift is an example of a single tectonic plate being ripped in two. Of course, divergent plate boundaries also exist on land. These eruptions were preceded by significant rifting and cracking on the ground surface, which are also emblematic of diverging plate movement. The diverging Eurasian and North American plates caused the eruptions of Eyjafjallajökull (in 2010) and Bardarbunga (in 2014). The island of Iceland is a part of the Mid-Atlantic Ridge. Some ocean ridges reach the ocean surface and create landforms. Most submarine volcanoes are found on ridges thousands of meters below the ocean surface. This submarine volcanic activity accounts for roughly 75 percent of the average annual volume of magma that reaches Earth’s crust. Vents and fractures (also called fissures) in these mid-ocean ridges allow magma and gases to escape into the ocean. These ridges are interconnected, forming a continuous volcanic mountain range nearly 60,000 kilometers (37,000 miles)-the longest in the world.Īnother divergent plate boundary is the East Pacific Rise, which separates the massive Pacific plate from the Nazca, Cocos, and North American plates. The upward movement and eventual cooling of this buoyant magma creates high ridges on the ocean floor. Along the Mid-Atlantic Ridge, hot magma swells upward and becomes part of the North American and Eurasian plates. Here, the North American and Eurasian tectonic plates are moving in opposite directions. The Atlantic Ocean is home to a divergent plate boundary, a place called the Mid-Atlantic Ridge. They never really separate because magma continuously moves up from the mantle into this boundary, building new plate material on both sides of the plate boundary. The two types of plate boundaries that are most likely to produce volcanic activity are divergent plate boundaries and convergent plate boundaries.Īt a divergent boundary, tectonic plates move apart from one another. Volcanoes are most common in these geologically active boundaries. Sometimes, the plates collide with one another or move apart. They move only a few centimeters per year. These plates are not fixed, but are constantly moving at a very slow rate. These plates are huge slabs of Earth’s crust and upper mantle, which fit together like pieces of a puzzle. Most volcanoes form at the boundaries of Earth’s tectonic plates. Volcanologists closely monitor volcanoes so they can better predict impending eruptions and prepare nearby populations for potential volcanic hazards that could endanger their safety. About 350 million people (or about one out of every 20 people in the world) live within the “danger range” of an active volcano. Eruptions can create new landforms, but can also destroy everything in their path. Volcanoes are incredibly powerful agents of change. Many others are dormant volcanoes, showing no current signs of exploding but likely to become active at some point in the future. About 1,900 volcanoes on Earth are considered active, meaning they show some level of occasional activity and are likely to erupt again. They are found throughout the world, forming ridges deep below the sea surface and mountains that are thousands of meters high. Volcanoes come in many different shapes and sizes but are most commonly cone-shaped hills or mountains. Along with lava, volcanoes also release gases, ash, and, solid rock. This molten rock is called magma when it is beneath the surface and lava when it erupts, or flows out, from a volcano. A volcano is a feature in Earth’s crust where molten rock is squeezed out onto the Earth’s surface.

Consider the servers with below details are used for Demo.ĪWS Redshift – 172.19.12.116 (Database as a Service)Īs Redshift is a database as a service, We just have an endpoint to connect. Read & write access to an AWS S3 Bucket.Database name, Schema_name should be same as MySQL Database name of the tables to be replicated.Following MySQL configuration should be enabled on MySQL.All the tables to be replicated must have a primary key.So It’s mandatory that Binary log format on MySQL is ROW. Therefore Statement information is not supported for heterogeneous deployments. It stores transactional data from different data servers in a universal format using the replicator service acting as a master, That could then be processed Applier / Slave service.Īll the raw row-data recorded on the THL logs is re-assembled or constructed into another format such as JSON or BSON, or external CSV formats that enable the data to be loaded in bulk batches into a variety of different targets. The Transaction History Log (THL) acts as a translator between two different data sources. The extractor component reads data from MySQL’s binary log and writes that information into the Transaction History Log (THL). There are three major components in tungsten replicator Tungsten Replicator includes support for parallel replication, and advanced topologies such as fan-in and multi-master, and can be used efficiently in cross-site deployments. Tungsten Replicator is an open source replication engine supports data extract from MySQL, MySQL Variants such as RDS, Percona Server, MariaDB and Oracle and allows the data extracted to be applied on other data sources such as Vertica, Cassandra, Redshift etc. So, I take this opportunity to guide on how to replicate the specific set of tables from MySQL to AWS Redshift using Tungsten replicator. Out of which Amazon Redshift replication is a bit complicated as Amazon Redshift is a Database as a service (DBaaS) and the process is not straightforward. Our team provided solutions to replicate data from MySQL to Vertica, Amazon Redshift, Hadoop. In our work, We used to get a lot of requirements for replicating data from one data source to another. The measurement involves determining the velocity of the falling sphere. If the fluid has a low viscosity, it offers less resistance to flow, so the ball falls faster. This makes sense: if the fluid has a high viscosity it strongly resists flow, so the sphere falls slowly. The faster the sphere falls, the lower the viscosity. This exercise uses one of the oldest and easiest ways: we will simply see how fast a sphere falls through a fluid. There are many ways to measure viscosity, including attaching a torque wrench to a paddle and twisting it in a fluid, using a spring to push a rod into a fluid, and seeing how fast a fluid pours through a hole. As expected, hawaiian volcanoes erupt more fluid lavas (called basalt) than do the Cascade volcanoes, which erupt a lava called andesite. Thus, shield volcanoes like we have in Hawai'i have gentle slopes (less than 10 degrees), while stratovolcanoes like the Cascades in the northwestern mainland are much steeper (roughly 25 degrees). Also, the more viscous the magmas a volcano erupts, the steeper the volcano. The more viscous the magma, the fatter the lava flow. Viscosity also affects the shapes of lava flows and the mountains they erupt from. On the other hand, when more viscous (higher viscosity) lavas do erupt, they usually do so explosively. The more fluid a magma, the more likely it is to erupt. In fact, one of the major differences between styles of mashed potatoes is the viscosity of the starchy mass: some people like their potatoes running and teeming with milk and butter (they are fans of low-viscosity potatoes), while others like their potatoes drier and stickier, so they almost crack rather than flow (these people are devoted to high-viscosity potatoes). For example, pushing a spoon with a small force moves it easily through a bowl of water, but the same force moves mashed potatoes very slowly. Viscosity is an internal property of a fluid that offers resistance to flow. To determine how fluid a liquid really is by measuring its viscosity. These fluid lava flows can flow great distances from vents in either pāhoehoe and ‘a‘ā forms, although fissures sometimes erupt blocky lava flows.Teacher Page: Viscosity Hawai'i Space Grant Consortium, Hawai'i Institute of Geophysics and Planetology, University of Hawai'i, 1996 While lavas of any compositions may be erupted from fissures, basaltic lava flows are common.

The dike swarms that are the source of the Columbia River Basalts have a north-northwest orientation, with fissure lengths reaching as much as 110 miles (180 km).Ĭolumbia River Basalts are found in several NPS sites in the Northwest including Nez Perce National Historical Park, John Day Fossil Beds National Monument, Lake Roosevelt National Recreation Area, and Manhattan Project National Historical Park. They were erupted from fissures, mostly in eastern Oregon, southeastern Washington, and Idaho, and accumulations of lava flows up to 13,000 ft (4,000 m) thick filled much of the Columbia Basin, with lava flows traveling as far as the Oregon-Washington coast. They were erupted within a short time period, mostly between 16.7 and 15.5 million years ago. The Columbia River Basalts are flood basalts (or plateau basalts) meaning that they are thick accumulations of lava flows that were erupted within a short period of time and that cover a vast geographic area.Ĭolumbia River Basalts cover more than 81,000 square miles (210,000 square km), and have an estimated volume of 50,000 cubic miles (210,000 cubic km). The Columbia River Basalt Group is the product of the largest eruptions in North America’s history. Kīlauea and Mauna Loa are large shield volcanoes with extensive rift zones on their flanks where fissure eruptions can occur.
