2/28/2023 0 Comments Cgi stands forWhat does CGI stand for in English?Ĭomputer-generated images computer-generated imagery: digital graphics used in visual media, often in the form of 3D animation. Marvel Cinematic Universe (MCU) films are some of the most CGI heavy movies in the history of filmmaking and each release features only the latest in CGI technologies. What is CGI in Marvel?ĬGI animation is an incredibly painstaking process that’s why movie outfits spend millions of dollars on special effects. That means the average cost per minute to use CGI in a feature film is around $570,000. To start off with, production costs over the past decade range between $34 million and $79 million for CGI alone. 30 hours per frame as opposed to 1/30 of a second per frame in any modern video game, that’s a difference of about 3.24 million times of rendering time unless my math is wrong. Its complexity required 30 hours to render each frame, with 4,000 computers rendering one frame at a time. How long does it take to make a CGI movie? The longest film ever made was the 85 hour The Cure for Insomnia (USA 1987), directed by John Henry Timmis IV and premiered in its entirety at The School of the Art Institute of Chicago, USA from 31 January to 3 February 1987. CGI is instrumental in the making of movies and television shows and serves as the primary method for creating 3D-computer graphics for video games. What was the first sound movie? Why is CGI used in movies?ĬGI is a subcategory of visual effects (VFX), imagery filmmakers create or manipulate that does not exist in the physical environment being captured on film or video. 2/28/2023 0 Comments Timi risk score for nstemiThis study suggests that these other scores may be potentially useful and should be further researched.Ĭopyright © 2012 Elsevier Inc. There are other potentially useful ACS risk scores available however these have not undergone rigorous validation. TIMI and GRACE are the risk scores that up until now have been most extensively investigated, with GRACE performing better. For STEMI, 15 studies with 134,557 patients with derivation scores, and 17 validation studies with 187,619 patients showed a pooled c-statistic of 0.77 (95% CI = 0.71-0.83) and 0.77 (95% CI = 0.72-0.85) for TIMI at short and long term, and a pooled c-statistic of 0.82 (95% CI = 0.81-0.83) and 0.81 (95% CI = 0.80-0.82) for GRACE at short and long terms respectively.

More on the “trojan horse analog problem” here. Do not accept anything less than a ‘purely electro-mechanical analog meter with no electronic components.’ Be aware that some utilities have been installing meters that appear to be analogs but in fact are fully activated ‘smart’ meters. They also use switch mode power supplies, linked to dirty electricity and health problems.īottom line: A ‘smart’ meter is any utility meter that contains electronic components. “Radio Off” Digital Meters can still act as a surveillance device. Though this is a wired system, ‘dirty electricity’ used to send the signal also radiates into living spaces from unshielded wiring. PLC (Power Line Communication) uses the power lines to transmit utility usage data. Includes ‘bubble up’ meters that transmit all the time, and ‘wake up’ systems that transmit when they receive a signal. Enables remote shut off & control of appliances.ĪMR (Automatic Meter Reading- or ERT) meters are typically wireless one-way meters that report usage to utility personnel in a vehicle with a handheld device. ALL of the meter types below are ‘smart’ and are associated with health and safety problems:ĪMI (Advanced Metering Infrastructure) enables two-way wireless communication between the utility and the meter. Many insist that their meters aren’t the ‘smart’ meters that have been causing all the problems. Utilities use a dizzying list of acronyms and technical terms to describe their ‘smart’ grid systems. There are a very few mechanical meters which have a wireless-transmitting capability, which can only be identified by measuring RF emissions. Recent “smart” meters often have the word “smart” on the front, but absence of this label is no guarantee it isn’t transmitting. “Smart” meters have digital displays and plastic casings which you cannot see into. Non-transmitting analog (mechanical) electric meters typically have 5 small clock-like dials and a glass casing which allows you to see the spinning dial inside. See these photos of “smart” meters and these photos of analog meters, and compare to your own. Q: How do I know if I have a “smart” meter or not? Local utility companies in many states have been approved to install “smart” meters but this does NOT mean you have to accept them on your home or business. However, in that Act, there was NO mandate to force all residential customers to accept installation of “smart” meters–only that they would be offered. “Smart” meter planning in the United States is related to the Energy Act of 2005 and administered by the US Dept of Energy, the FCC, and each state’s public utilities commission (PUC). Wireless water meters are also being installed in many regions. Electric smart meters are replacing older analog style meters, while gas “smart” meters are generally small devices attached to existing gas meters. Smart Meters are part of a larger plan to change the electricity grid to a “smart” grid–though there is controversy about whether the customer meter is actually crucial to that change. Some meters (AMI mesh networks) also contain other capabilities, such as remote shut-off. “Smart” Meters are digital utility meters that send customers’ detailed usage information to the utility using a radio-frequency transmitter (or over the power lines in the case of Powerline Carrier (PLC) systems.

The exponent applies only to the number that it is next to. The expression 10 3 is called the exponential expression.ġ0 3 is read as “10 to the third power” or “10 cubed.” It means 10 Ĩ 2 is read as “8 to the second power” or “8 squared.” It means 8 ĥ 4 is read as “5 to the fourth power.” It means 5 ī 5 is read as “ b to the fifth power.” It means b *in American English, 1 x 10 12 = one thousand million in British English.Įxamples of simple math using scientific notation AdditionWe use exponential notation to write repeated multiplication, such as 10 Its value is 70 times the value of the blue digit. Its value is 10 times greater than the value of the blue digit. Examples of Scientific Notation, Metric Prefixes, and Symbols Word Which statement is true about the red digit in the following number. So it's 1 times 10 times 10 times 10 times 10 times 10. Well, 10 to the fifth power is the same thing as taking a 1 and multiplying it by 10 five times. Using a pocket calculator with an exponent key, usually labeled EX or EE or EX, the number: 4.3 x 10 5 is entered as 4.3 EX 5. We are asked what is 10 to the fifth power equivalent to. Here are some alternate forms of notation for the same numerical values: 3.2 x 10 8 Note that the negative sign in the exponent means the value is less than one. For example, the size of an atom is on the order (or about) a few Ångströms (Å) which is defined as: Not only can one use scientific notation to express large numbers but also very small numbers. Note that 2.0 is the coefficient and 30 is the exponent. For example, the distance from the Earth to the Sun is referred to as the Astronomical Unit (AU) and is: 1 AUĪnother dimension to illustrate this kind of notation is the mass of the Sun expressed in units of kilograms (kg): Mass of the Sun Consequently, scientific notation has been introduced to deal with such quantities. Microscopy is the subject of very small numbers. Scientific Notation:Īstronomy is the subject of very large numbers. Thus we can now proudly state that 1 nm = 10 -3 m. Description 5.NBT.2 Explain patterns in the number of zeros of the product when multiplying a number by powers of 10, and explain. For example, milli- always means one thousandth. For the names of larger numbers, or numbers that are not a power of 10. In the third worksheet, students are given numbers and asked to rewrite them as powers of ten. English names of the first 10000 powers of 10. The second worksheet evaluates expressions with single digit numbers multiplied by powers of ten. They multiply the unit by some power of 10. The first worksheet ask students to evaluate simple powers of ten up to 10 8. There is a method to the prefixes centi-, milli-, etc. (This is a convenient unit for high-power microscopes, with which one can look at objects as small as a few micrometers. (This unit is often used because a typical atom is a few Ångströms in size.) The wavelength of yellow light in a vacuum may be called 5750 Å or 575 mµ or 575 nm or 0.575 µm. Unfortunately, many different names are used. This much is fine for everyday lengths, but for light we have to use even smaller units of length because its wavelength is so small. Positive exponents a number greater than 1 exponent of 10 is a positive whole number value of the exponent number of places the decimal point must be moved so. It is easier to use the metric system where everything goes by powers of 10: 1 meterġ0 -3 m ~ 1/25 inch (width of lead in pencil) That gets messy if we want to convert from miles to inches. But there are 12 inches in a foot, 5280 feet in a mile and so on. You can multiply any number by itself as many times as you want using this notation (see Exponents), but powers of 10 have a special use. For people's heights we use feet and inches. No one gives the distance between cities in inches we use miles. Later on, introduce students to the exponent form as they will already know how to multiply or divide with powers of ten and can focus on learning the relationship between the exponents and the number of zeros they need to work with. We also have some worksheets with the power of ten in which math learners. People find it cumbersome to speak of units of measurement like "one ten thousandth of a billionth" of an inch, or even "ten to the minus thirteenth" (10-13) inches so they devise different names.
