electricfoxy Electrical Engineering and Computer Science | 6.004 Computation Structures, Spring 2009 Table of mathematical symbols When reading the list, it is important to recognize that a mathematical concept is independent of the symbol chosen to represent it. For many of the symbols below, the symbol is usually synonymous with the corresponding concept (ultimately an arbitrary choice made as a result of the cumulative history of mathematics), but in some situations a different convention may be used. For example, depending on context, the triple bar "≡" may represent congruence or a definition. Further, in mathematical logic, numerical equality is sometimes represented by "≡" instead of "=", with the latter representing equality of well-formed formulas. In short, convention dictates the meaning. Each symbol is shown both in HTML, whose display depends on the browser's access to an appropriate font installed on the particular device, and in TeX, as an image. Guide This list is organized by symbol type and is intended to facilitate finding an unfamiliar symbol by its visual appearance. Basic symbols
Life long experimenter - It can be done Electronic Circuits on Circuit Exchange International (CXI) Q&A: Open Source Electronics Pioneer Limor Fried on the DIY Revolution | Magazine Limor Fried— building the DIY revolution one resistor at a time. Photo: Andrew Tingle Limor Fried is a maker’s maker. Sure, she’s got prime geek credentials: She earned an electrical engineering degree from MIT, invented several delightfully nerdy things to do with Altoid tins, and reverse-engineered the legendary Roland TB-303 synthesizer. Now she runs Adafruit Industries, a New York City company that makes open source electronics kits and components for the growing tide of DIYers who are inventing the future. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. At Adafruit's New York headquarters, where accelerometers and tiny OLED displays count as office supplies, even plastic cups are put to inventive use.Photo: Andrew Tingle Chris Anderson: We’ve had the notion of garages, workshops, sheds, and DIY tinkering for a long time. Limor Fried: One of the things about doing projects is that documenting them and sharing them with people used to be really difficult. Limor Fried: Exactly! 3-D Printers
M.C.S. home page - Мозилин фајерфокс (Mozilla Firefox) Capacitor Voltage Change This curve fitted equation can then be used in LTSpice to model the Y5U capacitor, with its capacitance versus voltage relationship. To model a non-linear capacitance in LTSpice, it's necessary to write an equation relating charge (in Coulombs) versus bias voltage. This mathmatical relationship is written into the value of the capacitor (instead of so many uF or pF) as Q=f(x) where X is the pre-defined variable in LTspice representing the instantaneous voltage across the capacitor. More generally, the charge Q stored in a capacitor is: C(V) is the relationship between capacitance and applied voltage, in this case, as determined by our 7th order polynomial fitted to the measured C versus V data: In a theoretically perfect capacitor of constant value, of course, the relationship between charge and voltage is simple; Q=CV where Q is the charge in Coulombs, C is the capacitance in Farads and V is the voltage in Volts.
