![]() What I meant was, how to mimic the crankshaft signal pattern on the simulator circuit that feeds the simulated waves into the CarDuino. While in traffic, you can only afford split second glances at your CarDuino screen anyway, so it does not add any value to have an rpm reading that is dead precise. 3163 rpm would show up on the TFT screen either as 3160 or 3150. Once my CarDuino can reliably calculate the revs, I was going to round off whatever figure it comes up with to the nearest multiple of ten, maybe even fifty, before displaying it on the screen. For simplicity's sake, it will definitely be the way forward to just count the rising edges as they happen, and simply assume that one crankshaft turn is 32 teeth/ 32 risings. No, I completely understand what you're saying. Is that an issue for a graphical user interface? Basically itd say 3000 RPM on the screen, but in reality it could be between 29 ish. So we know esentially, we are 1600 ticks +/- 4 ish (might be +/- 2.someone may clarify).īeing 4 rises/ticks out out of 1600 = 0.25% inaccuracy. Now we don't know where the crank ended on a cycle.might be in a "dip" bit where there is a gap or not.but there are only 4 in that last cycle. ![]() You'd also be using an interupt and a timer to time the time between 2 interupts on a pin.even more hardware and software usage with more complication.Įxample, while driving at 3000rpm, the crankshaft will turn from its current position 3000/60 times = 50 revolutions of the crankshaft in a second. You'd use an interrupt for what you want, which causes "some" code blocking. I think you are adding a lot of complication for the sake of say 0.3% accuracy in revs for a user's graphical user interface. Then reset the timers to 0 again (TCNT0 = 0 etc.) ready for the next loop round. You will just be incrementing them using an "external clock source".the crankshaft sensor/fuel injector sensors/ etc.Īll your main loop will then do, is every cycle of the loop() you will check the time gone by (millis() on a spare timer) and then get the values held in the timer registers (like TCNT0, TCNT1, TCNT2 etc.). ![]() The timers are hardware.you can only set one software variable for them, the "overflow".but you wont be doing that. You will be using timers to count pulses from the crankshaft. ![]()

![]() In real-world use, the actual sustained Wi-Fi speeds fluctuate a great deal and are generally much lower than the cap speeds. Note that these are the ceiling speeds of the respective standards. For existing Wireless-N (802.11n) clients, the devices also supports the top tier of this standard to deliver up to 450Mbps data speeds. This means it supports all existing Wi-Fi clients, regardless of their standards and platforms.Īs a high-end product, the new networking device supports the current top tier (three-stream) of the new 802.11ac standard, which is available only on the 5GHz band, to offer wireless data speeds of up to 1.3Gbps to 802.11ac-enabled clients. Seamless combination: A Wi-Fi router and a network storage serverĪt its core, the Time Capsule is a true dual-band router, offering Wi-Fi coverage on both 2.4GHz and 5GHz frequency bands at the same time. ![]() And finally, I'm also a little surprised and disappointed that there's no support for AirPlay, which is available in the AirPort Express that came out last year. It can also be used to archive the content stored on the internal drive to an external one, for data safety. This port can be used to host a printer or an external storage device to supplement the Time Capsule's internal drive. By now you'd think Apple could use the support for USB 3.0 on its AirPort devices. What's also disappointing is the USB 2.0 port. ![]() It's kind of disappointing that the Time Capsule doesn't offer more LAN ports, since there seems to be enough space to add more. All of these ports are Gigabit compatible, offering up to 1,000Mbps data speeds. On the back, stacking up in a vertical array, there are the usual three LAN ports (to connect wired clients, such as a Mac Pro), and one WAN port (to connect to an Internet source, such as a broadband modem). ![]() The light changes to amber or flashes to indicate that the device needs attention.

Learn more about HUAWEI eKit and the channel opportunities here.A Printer Driver supporting solution Menu Ex is not Installed With a wide range of innovative distribution products and solutions tailored to the unique needs of SMEs, Huawei is well-positioned to drive digital transformation across various industries.Īs the digitalisation of SMEs continues to gain momentum, Huawei's dedication to its distribution partners and its comprehensive product portfolio will play a pivotal role in ensuring the success of SMEs in the evolving digital landscape. Huawei's strategic move into the distribution business, guided by the principles of HUAWEI eKit, demonstrates the company's commitment to empowering SMEs on their digitalisation journey. Most beneficial of all for the SME is that it requires no technical skills to deploy. It is being pitched as an ideal solution for boundless collaboration and communication to fit everything from regular meeting rooms, executive offices, and open office areas. This device is equipped with Bring Your Own Meeting (BYOM), HD immersive meeting quality, Wi-Fi 6 for direct projection, and ultra-low writing latency, easily adapting to mainstream cloud meeting apps. Distributors can bring the IdeaHub S2-75 to their channel and the eventual end customer. HUAWEI eKit in ActionĪ good example of the potential of HUAWEI eKit can be seen with the IdeaHub interactive display, one of the solutions available to the channel through the platform. At Huawei Connect 2023, the company launched another 17, including eKitEngine S220 and S310 series, L2 and 元 switches that support full 10GE uplink and Perpetual PoE, eKitEngine AP160, a wall plate AP that is 8 mm thin and supports the unique DVFS technology and other new products that support SAN/NAS hybrid storage.īy the end of the year, HUAWEI eKit will have more than 50 products with similar transformative potential available to distributors. HUAWEI eKit features a wide range of products across many product categories into this sub-brand, including intelligent collaboration, wired and wireless networks, IP + optical access networks, storage, and IT platforms. Across the first half of 2023, there were 31 products released within HUAWEI eKit. ![]() ![]() It’s the “one stop shop” approach, which is increasingly valued among small businesses that are constrained across both resources and capabilities, and really need IT to be a matter of set-and-forget. It allows those smaller to adopt a broad transformation agenda, without requiring enterprise IT capabilities to deploy and maintain.įor those in the channel, HUAWEI eKit is an opportunity to present solutions that are easy to buy, sell, install, maintain, and manage. This has been built off the back of over 30 years of experience by Huawei in digital transformation, and is a pure channel play, giving distributors the tools that they need to help those lower-level resellers and integrators effectively bring Huawei technology to their customers.Įssentially, it’s a sub-brand of Huawei that is specifically designed for the distribution market, that integrates policies, products, solutions, services, and digital tool platforms to build end-to-end enterprise digital solutions. The concept behind HUAWEI eKit was developed to better support SMEs by providing versatile products and solutions that specifically meets their needs. How HUAWEI eKit supports innovation for SMEs Developing such tailored solutions can be resource-intensive for IT vendors, however distributors, integrators, managed services providers and other channel supports are often the only pathway SMEs have to the kind of tailored solutions they need. Providing Tailored Solutions: Though they are resource-limited, SMEs often require customised IT solutions that cater to their specific business processes.However, the channel specialises in building these kinds of relationships, and for this reason channel organisations are always looking for vendor partners that can support their abilities to deliver seamless experiences to SMEs. This is an area that large vendors typically struggle with, because they cannot provide a direct level of service that the SME is looking for. Building Relationships: SMEs often prefer to work with suppliers who understand their business and can provide personalised service. ![]() However, understanding these needs can be difficult for the IT channel due to the lack of standardised IT infrastructure and processes in SMEs. They require IT solutions that are flexible, scalable, and easy to use. Understanding Needs: SMEs often have unique and diverse needs compared to larger enterprises.SMEs can struggle with accessing technology from major vendors for several reasons, and consequently this can make adopting innovative technology challenging for them. ![]() ![]() ![]() The viscosity of an aqueous solution can either increase or decrease with concentration depending on the solute and the range of concentration. This is also the reason oils tend to be highly viscous, since they are usually composed of long-chain hydrocarbons. More dramatically, a long-chain hydrocarbon like squalene (C 30H 62) has a viscosity an order of magnitude larger than the shorter n-alkanes (roughly 31 mPa This effect can be observed for the n-alkanes and 1-chloroalkanes tabulated below. Substances composed of longer molecules tend to have larger viscosities due to the increased contact of molecules across layers of flow. One of the key predictions of the theory is the following relationship between viscosity μ For this reason, measured viscosities of the noble gases serve as important tests of the kinetic-molecular theory of transport processes in gases (see Chapman–Enskog theory). The simple structure of noble gas molecules makes them amenable to accurate theoretical treatment. By contrast, pressure is omitted since gaseous viscosity depends only weakly on it. The temperatures corresponding to each data point are stated explicitly. Where data points are unavailable for 25 ☌ or 1 atmosphere, values are given at a nearby temperature/pressure. Here "standard conditions" refers to temperatures of 25 ☌ and pressures of 1 atmosphere. Viscosities at or near standard conditions Consequently, its kinematic viscosity is around 2 to 40 centiStokes. ![]() The density is usually on the order of 0.5 to 5 kg/m^3. Consequently, if a liquid has dynamic viscosity of n centiPoise, and its density is not too different from that of water, then its kinematic viscosity is around n centiStokes.įor gas, the dynamic viscosity is usually in the range of 10 to 20 microPascal-seconds, or 0.01 to 0.02 centiPoise. The density is usually on the order of 1000 kg/m^3, i.e. In engineering, the unit is usually Stoke or centiStoke, with 1 Stoke = 0.0001 m^2/s, and 1 centiStoke = 0.01 Stoke.įor liquid, the dynamic viscosity is usually in the range of 0.001 to 1 Pascal-second, or 1 to 1000 centiPoise. In engineering, the unit is usually Poise or centiPoise, with 1 Poise = 0.1 Pascal-second, and 1 centiPoise = 0.01 Poise.įor kinematic viscosity, the SI unit is m^2/s. ![]() This page lists only dynamic viscosity.įor dynamic viscosity, the SI unit is Pascal-second. Kinematic viscosity is dynamic viscosity divided by fluid density. The values listed in this article are representative estimates only, as they do not account for measurement uncertainties, variability in material definitions, or non-Newtonian behavior. Of all fluids, gases have the lowest viscosities, and thick liquids have the highest. Viscosity is measured using a viscometer. For instance, honey hasĪ much higher viscosity than water. It corresponds roughly to the intuitive notion of a fluid's 'thickness'. Dynamic viscosity is a material property which describes the resistance of a fluid to shearing flows. ![]() ![]() ![]() It Also Includes Word Problems Involving Multiplication.

![]() ![]() In that case, the engineer was probably trying to make aesthetically pleasing contours that don’t reflect the actual CAD model that s/he created. Suppose you see nice-looking curving contours that don’t hit any of your spot elevations or that cause flags in your breaklines. If you ever see jagged or zigzagging contours, that means that the engineer probably used a poor-quality surface to generate the contours. This method can be good or bad depending on the quality of the surface they made. Some engineers build the DSM and then generate contours that directly trace that surface. CONTOUR LINES TO DETERMINE BREAKLINES?Ĭontour lines can be molded differently in CAD, depending on the engineer. Breaklines are critical to creating an accurate surface model because it is not enough to have just the data alone it is the interpolation of that data that gives you the model's shape. This line data forces the surface to create triangles that connect the vertices on the breakline. They are lines used to connect data representing a specific surface, such as the centerline of a road, a ridgeline, or a ditch's flowline. For example, spot elevation points tell you the elevation of various drainage features and give you the top and bottom of retaining walls, among other things.īreaklines are a way of manipulating the surface triangles. These points are critical for construction because they provide you with specific locations above or below their surroundings. Spot elevations tell you the actual elevation of a particular point, both existing and proposed, which can be used for planning purposes and for creating 3D models. ![]() Precise grading plans will provide you with better drainage management, accurate building foundation depths, and they will also account for the various landscaping features.Ī spot elevation is a point on a map that identifies the height above mean sea level. Some reasons for this are: it will help you get your permits easier, and it allows your earthwork contractors to provide you with better estimates. When it comes to grading plans, the quality of the plan is the key factor. For this reason, topographic maps are made up of different line types, colors, and shadings, which give you a visual of the changes in elevation and terrain shape. ![]() These models are used for creating topographic maps.Ĭreating, or even reading, topographic maps can be overwhelming because we live in a 3D world, and it's not necessarily easy to represent it all on a 2D map. The difference between the DSM and the DTM is that the DSM includes all objects on the earth's surface, whereas a DTM represents only the bare ground. These models provide a 3D representation of terrain elevation data. A Triangulated Irregular Networks (TIN) is a representation of a continuous surface consisting entirely of triangular facets. A Digital Elevation Model (DEM) is often used as a generic term for Digital Surface Models (DSMs) and Digital Terrain Models (DTMs). So, we will start with defining DEMs, DSMs, DTMs and TINs. We can't jump right into answering that question without providing you with some terms related to this topic that are important for you to know. We are often confronted with that question and are here to help you figure it out. Are you having trouble deciding when to use spot elevations versus contour lines to determine your breaklines? Well, don't worry because you're not alone. ![]() ![]() It's a violation of the flag code that prohibits altering of the flag in this manner & an affront to the #BlackLivesMatter protests that I & others were a part of. Gabriel Acevero (D-Montgomery) backed Elrich's move, writing on Twitter: "This is not the American flag. "Under my administration, we are committed to improving police relations with the community and will immediately address any action that stands against our mission."Įlrich's decision drew decidedly mixed responses from the public. "The flag provides a symbol of support to some but it is a symbol of dismissiveness to others," he said in a statement. Two days after police announced the flag would be displayed on station property, Montgomery County Executive Marc Elrich said the flag would not be on view to the public. ![]() The flag has been used in association with the Blue Lives Matter movement, a pro-police group formed in response to Black Lives Matter and its protests against police violence toward black people. The announcement prompted immediate pushback from residents who said the flag excuses police violence against black residents, and who pointed out that the flag was seen alongside Confederate flags at the deadly white supremacist rally in Charlottesville in 2017.

In these cases, the canton may be called simply the union. Following the practice of British ensigns, a canton sometimes contains a symbol of national unity such as the blue field and white stars of the U.S. For instance, British ensigns have the Union Jack as their canton, as do their derivatives such as the national flags of Australia and New Zealand. The canton of a flag may be a flag in its own right. Main article: Canton (flag) National flag of the Republic of China (Taiwan) National flag of the United StatesĪ canton in a flag is a rectangular area at the top hoist corner of a flag, occupying up to a quarter of the flag's area. The aspect ratio is usually defined around 1:1. Togo: The golden ratio which is roughly 1.618035 Aspect ratio of 2:3.23607 or ~ 8:13. ![]() Switzerland: (Square-shaped) Aspect ratio of 1:1.Qatar: The largest aspect ratio of any national flag, the flag's width 2.545 times as large as the height.Nepal: The only national flag that is not rectangular, being made with 5 sides.* Most common aspect ratio is 2:3, followed by 1:2. Sets of flags in this list within the same category may represent countries' shared connections, or the design similarity may be a coincidence. Many countries with shared history, culture, ethnicity, or religion have similarities in their flags that represent this connection. Sometimes these flags are used to represent languages. Common design elements of flags include shapes such as stars, stripes, and crosses, layout elements such as including a canton (a rectangle with a distinct design, such as another national flag), and the overall shape of a flag, such as the aspect ratio of a rectangular flag (whether the flag is square or rectangle, and how wide it is) or the choice of a non-rectangular flag. Flags come in many shapes and designs, which often represent something about the country or people that the flag represents. A national flag is a flag that represents and symbolizes a country. ![]() ![]() ![]()
