Thus for integer dividers, the highest frequency we can pass in is 42 MHz (with divider 2). If you take a look at the function PWMC_ConfigureClocks in pwmc.c, you will see that the highest PWM frequency can be accommodated as the function input is 42 MHz, this is because inside the function it calls FindClockConfiguration which in turn ensures that the frequency parameter passed in is less than the MCK frequency. The hardware PWM related functions are in /arduino-1.5.7/hardware/arduino/sam/system/libsam/source/pwmc.c, and the power management controller code are in /arduino-1.5.7/hardware/arduino/sam/system/libsam/source/pmc.c. Since the master clock (MCK) frequency is derived as (MUL+1)/DIV multiplied by the PLL frequency the result of the master clock frequency is 12*(13+1)/2=84 Mhz. SYS_BOARD_PLLAR defines the PLLA clock with a multiplier of 0xd (13). #define SYS_BOARD_MCKR (PMC_MCKR_PRES_CLK_2 | PMC_MCKR_CSS_PLLA_CLK) #define SYS_BOARD_PLLAR (CKGR_PLLAR_ONE \ In /arduino-1.5.7/hardware/arduino/sam/system/CMSIS/Device/ATMEL/sam3xa/source/system_sam3xa.c you will find the following definitions: They source code and binaries are located under /arduino-1.5.7/hardware/arduino/sam/system/ with the Arduino IDE distribution. Under the hood, Arduino IDE uses Atmel’s CMSIS compliant libraries. But before doing that, let’s take a look at how the the 84 Mhz clock frequency is obtained on the Due. via PWM controller) to generate our waveform rather than big-banging with software. We can do even better if we use the dedicated hardware (e.g. G_APinDescription.pPort -> PIO_CODR = g_APinDescription.ulPin G_APinDescription.pPort -> PIO_SODR = g_APinDescription.ulPin This is a huge improvement over the meager 200.7 kHz with digitalWrite. If we replace the digitalWrite with the following code, we will get an output square wave on pin 8 of roughly 16.8 Mhz. Of course, we can improve the code efficiency above quite a bit by using direct port manipulation. If the while loop is removed, the output frequency will drop to 145.4 kHz which is a 30% degradation from 200.7 kHz! But on Arduino Due, this difference is much more drastic. This overhead is not very noticeable on ATmega328p (116.9 kHz without the while loop versus 126.2 kHz with the loop). So if we did not use the while loop, extra instructions would be executed after outputting a LOW, causing the duty cycle to change and lowering the overall waveform frequency. By the way, the reason a while loop is used inside the loop() function is that the loop function has some extra instructions for checking the serial port. The Arduino code base is not very efficient and this code is actually not much faster than the same code on an ATmega328p (126.2 kHz for comparison, compiled with Arduino 1.0.5). For example, the following code on Due generates a 200.7 kHz square wave on pin 8 (compiled with Arduino 1.5.7): pin toggling), the highest achievable output frequency is actually quite abysmal. For an ATmega328p, the highest achievable PWM frequency is 8Mhz (square wave), so we should be able to generate much higher frequency signals on an Arduino Due. The processor core runs at 84 MHz, which is significantly faster than its 8-bit AVR counterpart ATmega328p which runs at 16 MHz. Arduino Due is based on Atmel’s ATSAM3x8E 32-bit ARM Cortext-M3 processor. While they were released almost two years ago, I have not really got a chance to look at these until quite recently. I just got myself a couple of Arduino Due boards.

According to Evgeny Leontiev, out of more than 700 pizzerias that currently operate in the world, including in Russia, the institution in Apatity will be one of the most beautiful and spacious. Currently, a design project is being developed in the parent company "Dodo Pizza". The investor has already chosen a place to place the pizzeria – in the city center, in a residential building on Fersman Street. And we express our gratitude to the Corporation for the Development of the Far East and the Arctic for its support." – We will monitor and study their experience. "We are sincerely glad that our partners are participating in such programs, thereby contributing to the business development of a unique region – the Far East and the Arctic," says Ivan Tikhov, Managing Director of Dodo Pizza Eurasia. A big role in making the decision was played by tax benefits for the next 5 years, which we will receive as a resident of the Russian Arctic." Our northern customers will be satisfied. We will make every effort to ensure that the Dodo network development department and the brand founder Fyodor Ovchinnikov personally have no doubts. Our company already has experience and a great desire to work in this field: the pizzeria in Apatity is the sixth franchise, the rest work in Moscow and the Moscow region. – In fact, you are not just renting an already promoted trademark, but you must become, first of all, a partner who corresponds to the company's values: the most important thing is a satisfied customer. "It is known that getting a Dodo Pizza franchise is both simple and difficult at the same time," said Evgeny Leontiev, General Director of A – 1 LLC. The agreement on investment activities was concluded with a single development institute-the Corporation for the Development of the Far East and the Arctic, subordinate to the Ministry of Regional Development.

Family owned since 1972, Elderly Instruments is a music store specializing in new, used & vintage guitars, banjos, mandolins, ukuleles and more. One of the oldest instruments found in civilizations across the world like the lyre in Greece or the banhu in China, the modern string section is the largest component of an orchestra. The modern variation has 16 strings, and there are 37 keys that slide. Lyre Harp is a string instrument known for its use in Greek classical antiquity. Immediately recognizable in both appearance and sound, stringed instruments are a cornerstone of our musical heritage. Researchers have recovered and studied archaeological evidence of an ancient stringed musical instrument crafted from deer antler in southern Vietnam. In addition to profound knowledge in the work of the old master makers, there is much handcrafting skill, extensive experience, and sensitivity and intuition which is required in order to fashion acoustic refinements. The Nyckelharpa, or keyed fiddle, is a 600 year old traditional Swedish instrument. I work entirely by hand-down to the finest detail. Many of these splendid pieces of wood are from the inventory of past violin makers and can be up to a hundred years old. Take a plastic tube, drill a set of holes in it, plug in a water pump, insert several pipes with electronic pickups attached to each and, you’ve got the weirdest water-powered musical instrument the world has ever seen. For my instruments, I use none other than acoustic wood seasoned for decades and of the highest quality. This is thanks to famous sitar players like Ravi Shankar and Anoushka Shankar as well as bands like The Doors, the Rolling Stones, and The Beatles, who all used it in some of their music in the 1950s and 1960s. It is my endeavour to shape and consummate that sound, and to make of each instrument not only a visual, but also a true acoustic happening.Īt the beginning of the procedure: the selection of the wood. The Sitar is probably the most famous traditional Indian stringed instrument in the West. The Lyres in this collection are the oldest surviving string instruments in the world. Each instrument is incomparable, having its very own character, its distinctive sound. You must have access to vector-based programs in order to edit the native files. While a vector image file has many advantages, there are compatibility issues when shared. This comes in handy when there are restrictions to file sizes or image storage. Image via NataliaKo.Ī vector image’s formulaic makeup keeps file sizes to a minimum in comparison to its raster counterparts. Elements like fonts render the same way-when sized up or down, they retain their quality. They’re made of paths and curves dictated by mathematical formulas. These paths and curves are produced exclusively through design softwares designed for vectors, like Adobe Illustrator or Sketch.ĭue to their algorithmic makeup, vectors are infinitely scalable, and remain smooth and crisp even when sized up to massive dimensions.Įven when scaled to substantial proportions, this pattern below remains clean and exact. Vectors use a different approach to image renderings. Some files take up additional data and use higher resolutions, while others take up less storage, but tend to be lower in resolution and quality. While all of these display pixels, each file format has its own distinct display settings. Raster files are saved in various formats: Avoid using them to design logos and icons. To edit these images, you need access to raster-based programs like Adobe Photoshop or Shutterstock Editor. For design work, it’s best to use these programs for photography and imagery only. And, when these images are uploaded online, the end result is a raster image. When you take a picture with a phone or a camera, the image is recorded as pixel data. Raster images are used in photography and digital applications. Tip: You can quickly cut down file size by reducing the resolution to 72 PPI for online images. An illustration with higher DPI (dots per inch) or PPI (pixels per inch) will be larger in size and data, which can be worrisome when there are limits to image storage or restrictions on uploaded file sizes. Image via NataliaKo.ĭue to the abundance of pixels in a raster image, the file sizes can be substantial. As a rule of thumb, it’s best to only downsize a raster image to avoid heavy pixelation. Obvious pixels make an image look unprofessional and unsightly. This is a key indicator of a raster-based image. Notice how the edges of the tropical pattern below become pixelated and jagged when magnified. When you zoom in on an image, the pixels become more apparent while the details of the image become blurry. The more pixels in an image the higher the quality, and vice versa. These pixels contain bits of color and, when combined, they build images. If you surf the web, chances are you’ve seen a raster image. Raster, or bitmap, images consist of tiny squares called pixels. Do you use raster or vector images? Raster images are made up of pixels, while vector images are formed by mathematical curves and paths.īeing comfortable with the ins and outs of both formats and how they translate when exported is an essential skill for every designer. With so many images to choose from online, it can be overwhelming to determine which file formats to begin with. Do you know the difference between a raster and vector file? This quick overview will help you differentiate for an improved design workflow. This outflow of air originating from within the downdraft undercuts and lifts the warm, moist air rising into the storm upwards. These form because cold air from the downdraft of a storm spreads horizontally when it hits the surface. Shelf clouds are ominous, wedge-shaped clouds that form on the leading edge of a thunderstorm. Shelf cloud over Enschede, The Netherlands. Often times, the damage in tornadic storms is higher from these straight-line winds than the tornado itself. After they hit the ground, they spread horizontally in all directions. They are very dangerous to airplanes because of the extreme turbulence, and since airplane pilots generally encounter them in the lower atmosphere where they are taking off or preparing to land, the stakes are even higher. Downbursts are rapidly falling parcels of air that can cause massive destruction over an area they impact. In some cases, this characteristic can be deadly. To make matters even more frigid, the air can be cooled further by hail falling through the downdraft and the sublimation of ice crystals into water vapor.īecause this air is cool, it is more dense than the surrounding atmosphere. Remember, it takes an unstable atmosphere with a sharp decrease in temperature with height to form a cumulonimbus cloud, so the tops of these clouds are often exceptionally cold. One would think that the temperature under a downdraft would be warm due to adiabatic warming associated with sinking air, but the temperatures under downdrafts are quite cool, especially when the storm is strong. A mature cumulonimbus has not only an updraft to continue supplying fresh air to the storm but a downdraft through which precipitation in the form of rain, hail, and even snow falls. The towering cumulus cloud was formed solely by updrafts. We’ve gone over the towering cumulus/ cumulus congestus/cauliflower cumulus clouds, so let’s go over the mature cumulonimbus cloud.ĭiagram of a typical thunderstorm. It’s these cauliflower clouds that lead to cumulonimbus clouds.īelow are the three stages of cumulonimbus development: a rising cumulus congestus cloud, a mature cumulonimbus with updrafts and downdrafts, and a dissipating storm with the updraft choked off. With cauliflower clouds, the atmosphere is unstable and has a high environmental adiabatic lapse rate (it cools sharply with elevation), so parcels of air near the ground are quite buoyant and tend to rise. See how the tops do not rise very high? This is because the air is fairly stable and does not allow cloud-producing updrafts to rise very high into the atmosphere. Cotton-ball cumulus are an indicator of fair weather. I like to refer to these clouds as cotton-ball and cauliflower clouds, respectively. The top one is humilis, and the bottom is congestus. Taken at Cahokia Mounds Museum and Interpretive Center. Notice how much more unstable the congestus skew-T is. The one on the left is for humilis, and the one on the right is for congestus. Take a look at the two skew-T plots below. The atmosphere above their LCL (lifting condensation level) is much more unstable, as as a result, the air parcel visibly denoted by the cumulus congestus cloud is a lot more buoyant. Just because a cloud is a cumulonimbus does not mean that it is producing lightning. Some people will tell you that cumulonimbus and thunderhead are synonymous, but this is not true. Smack these two words together, and BAM! you got a heapish cloud that rains. Humilis are known as “fair-weather cumulus,” because they are pretty short and fluffy due to a stable atmosphere overhead preventing them from growing them much further.Ĭumulus congestus, on the other hand, are the cumulus that have the potential to grow into cumulonimbus clouds that have the potential to produce vivid lightning, large hail, and even tornadoes. Cumulonimbus is a conglomerate of the Latin words cumulus (heap or pile) nimbus (water). For now, let’s just talk about humilis and congestus. Humulis are small and harmless, mediocris are slightly larger, congestus (also known as ‘towering cumulus’) reach high into the sky, and fractus are cloud fragments that have broken off from other clouds. There are four types of cumulus clouds: Humilis, mediocris, congestus, and fractus. Convective clouds are clouds that are formed by convection, which is simply the process of warmer air rising since it is less dense than the surrounding atmosphere. First, we’ll learn about some basic convective clouds known as cumulus clouds, and then we’ll learn about cumulonimbus clouds and thunderstorms.

However, we aren’t the only mammals who require the presence of leaves in their life. They return oxygen after taking carbon dioxide from the air, which humans need to breathe in. To thrive, leaves require carbon dioxide, which people and animals exhale. The Japanese red maple does contain chlorophyll, but it does also contain a red pigment called anthocyanin, which gives the leaves their color.Īnother interesting thing to teach children as they paint these fall leaves coloring pages is that eaves are the ones we have to thank for the air we breathe. There are other plants, such as the Japanese red maple, which have colored leaves all year. Evergreen trees, for example, are species that keep their leaves green year-round.
