downtime calculation formula

function from Matlab to verify: 1 CoV (mysample) Does the data we calculate be the same?Update: Suddenly discovered today, the original covariance matrix can also be computed, first let the sample matrix center, that is, each dimension minus the mean of the dimension, so that the average value of each dimension is 0, and then directly with the new sample matrix by its transpose, and then divided by (N-1). In fact, this method is also from the previous

Calculate the formula of compound interest: the annual profit is X %, and the profit after N years is (1 + x %) ^ n.Excel can be used for automatic calculation. The formula is: = power (1.08, n), 1.08 is 1 + year growth, and N is the number of years.Simple Estimation Method:72 rule-used to calculate how many years of investment is required to double the given ann

General MRP calculation formula: Net demand = gross demand + allocated volume + safety stock-plan in transit-actual in transit-available stockGross demand: the demand for inventory, manufacturing, and procurement is not considered, relative to the net demand. If it is an independent demand, then the gross demand = the main production plan demand/(1-The expected product is not enough ). For related requireme

center angle.Since R is determined, the arc AB length can be obtained as long as the angle θ between OA and OB is obtained. Arc AB = R * θ.Angle θ can be obtained through the vector formula: vector OA * vector OB = | OA | OB | cos θ.ThenCos θ = vector OA * vector OB/| OA | OB |= (Ax * Bx + Ay * By + Az * Bz)/R * R 4. Use latitude and longitude coordinates to represent three-dimensional Cartesian coordinates:Ax = R * cosAw * cosAjAy = R * cosAw * sinA

A wage calculation formula is usually defined in the wage system. For example, real-time = should be issued-should be deducted and so on. To calculate such an expression, the traditional method is to use a reverse polish expression to parse it. The following describes a simple method for computing. Use RPN. php In the pear library of PHP. Usage: Include 'include/pear/RPN. php ';// $ Expression = "(2 ^ 3) +

Today, a user wrote an email to me about the formula in the list calculation column when reading the SharePoint Portal Server 2003 deep guide, the book only states that "the calculated value formula also supports many functions. Readers can refer to the SharePoint help documentation for a deeper understanding." So the netizen asked me which functions can be used

there are too many characters in the number of vertices, The International Astronomical Federation adopted MJD in 1973, which was defined as MJD = JD-2400000.5. MJD starts at UTC, January 1, November 17, 1858. The calculation of the Confucian day = K-32075 + 1461 * (I + 4800 + (J-14)/12)/4 + 367 * (J-2-(J-14) /12*12)/12-3 * (I + 4900 + (J-14)/12)/100)/4 The calculation

There are 33pf filtering capacitors in the audio line, mainly filtering out MHz RF interference. How can this problem be calculated,Is the 217hz tdd_noise related to the filter capacitor? Or should I filter out series inductor or magnetic beads? 2 * pI * freq = SQRT (1/(L * C ))That is to say, This capacitive resonance point has the smallest impedance.You can check the encapsulation parameters of the resistance and capacitance of Murata.Generally, about 0402 of the encapsulation is about 0.5nh
