The model simulates three phase inverter with symmetric PWM modulation in which reference is sampled at the positive peak of the carrier and is held constant till the next positive peak of the carrier appears. The model demonstrates symmetric regular sampling at positive peaks of carrier and... Platforms: Matlab

The self-contained script demonstrates excess, volatility driven growth, in a rebalanced portfolio.Based on the paper "Benchmarking and Rebalancing" by Gabay and Herlemont, yats.com, 19 Septembre 2007, this script reproduces example 1, showing the long-term rebalancing excess growth rate g*.There...

In semiconductors, it is possible to make actual potential wells by sandwiching a d-deDUwelld-deDt layer of one semiconductor material (such as InGaAs) between two d-deDUbarrierd-deDt layers of another semiconductor material (such as InP). In this structure, the electron has lower energy in the... Platforms: Matlab

Returns NMR properties of the isotopesEXAMPLEH = isotopes('1H'), T = isotopes('3H'), or if the atomic mass is not specified, i.e. I = isotopes('H'), the function returns array of structures with data for all isotopes of the specified element. Isotopes('n') returns NMR properties for neutron.... Platforms: Matlab

The advantages of vector control provide variety of control choices in the PMSM drives. The simplest control strategy is the Zero d_axis current control (Constant Torque Operation) which is implemented in this model. The transient responses of torque, speed and 3-phase motor current are simulated. Platforms: Matlab

We compare computed temperature distributions using both pdepe and analytical solutions for different geometries (slab, cylinder and sphere). Solids are kept initially at uniform temperature. For t>0, the boundary surface is kept at constant temperature. Results show excellent agreement.... Platforms: Matlab

There are two issues with the Pearson type IV distribution: (I) the complex gamma function entering the normalization constant in the probability density function (pdf) and (II) the complex Gauss hypergeometric function entering the cumulative distribution function (cdf). For the complex gamma... Platforms: Matlab

A reaction object contains parameters that describe a chemical reaction scheme in terms of reagents, reaction steps, rate constants and equilibrium constants. The reaction can be evaluated to provide concentrations of species as a function of time and starting concentration. The reaction can also... Platforms: Matlab

CVBars are volume dependent as opposed to time dependent candlesticks; the close of the candle occurs when some volume criteria is met, not some variable timescale (1m, 5m, etc.)This is my first attempt to code and would be grateful for feedback, assistance, and importantly check to make sure...
