Calculation Formula of the stock transaction simulation part: L [start date Index]: [start date] index of the current day L [start date Index]: [start time] index of the current day L [total assets = balance + total market value] L [market value = cumulative quantity X closing price] calculated based on the maximum trading day close L [position = market value/total assets] calculated based on the maximum t

Terms: QPS = req/sec = number of requests/second [Method for Calculating PV and machines in QPS] QPS statistical method [http_load is generally used for Statistics]QPS = Total number of requests/(total number of processes * request time)QPS: Number of successful requests from a single process to the server per second PV computing per server per dayFormula 1: daily total Pv = QPS * 3600*6Formula 2: daily total Pv = QPS * 3600*8 Server ComputingNumber of servers = Ceil (total PV per day/tot

Tags: OS AR for SP art amp ad BS size The length of data that can be encrypted using RSA is determined primarily by the size of the key you're using. You appear to be using OAEP, so the maximum length is: keyLength - 2 - 2 * hashLength WhereKeylengthIs the length of the RSA modulus in bytes. You're using a 1024 bit key so: keyLength = 1024 / 8 = 128 And since you're using OAEP with SHA-1 hashLength = 20 So the maximum you can encrypt is: 128 - 2 - 2 * 20 = 86 Which is exactly what your

Calculation Formula of capacitor charge discharge time Set, V0 as the initial voltage value on the capacitor;V1 is the final charged or placed voltage value of the capacitor;VT is the voltage value of the capacitor at t time.Then,Vt = "V0" + (V1-V0) * [1-exp (-T/RC)]Or,T = rc * ln [(V1-V0)/(V1-Vt)] For example, a battery with a voltage of E is charged to a capacitor C with a initial value of 0 through

Android's definition of each resolutionHow to calculate when a picture is stored in a format argb_8888Memory consumption = picture length * Picture width/bytesPicture length = picture original long (Device dpi/folder dpi) Picture width = Picture original width (device dpi/folder dpi)Examples of validation are as follows:Picture size 200 * 320, device is red meter dpi is 320, belongs to xhdpi device.Verify that a picture is placed in hdpi and the following is the result of the code output:Dd/ma

Valve Game company Open source Gamenetworkingsockets[1], both support reliable data transmission, but also support unreliable data transmission, its data transmission is based on UDP, the implementation of TCP-friendly congestion control mechanism to ensure the fairness of bandwidth occupancy. [2] Its rate-control formula is based on a famous paper. Now, record its bandwidth calculation program here for a r

Tags: wireless communication db MW powerIn wireless communication, often hear such a device how many db, in fact, refers to the power, because the power is linear change, not easy to remember and calculate, then use the DB to represent, the complete unit is dbm, is multiplied.Calculation formulas for dbm and power1. The underlying values need to be remembered and then calculated based on this. Example: 0DBM=1MW,1W=1000MW2.DBM increases by 3, the power increases by 1 time times the need to multip
