Sales and procurement business foreign currency exchange rate handling

The multi-currency feature of SAP is a major selling point. The SAP butcher has written several articles about the exchange rate. Unfortunately, I am not a financial engineer. I don't know much about it. The following only lists the exchange rate issues I have encountered about the mm and SD modules. 1. Currency:Local currency, company code currency, account currency, price currency, document currency, post

Refers to the signal is modulated after the change in the unit time, that is, the number of times the carrier parameter changes in the unit time, such as 240 characters per second, and each character format contains 10 bits (a starting bit, 1 stop bit, 8 data bits), the baud

Frame rate, code stream and resolution

Http://blog.chinaunix.net/uid-22848040-id-1767590.html One, frame rate, code flow and resolution Frame rate Concept A frame is a static picture, a continuous frame to form an animation, such as TV images. We usually say that the number of frames, in short, is how many pictures are transmitted in 1 seconds, and it can be understood that the graphics processor can refresh several times per second, usually exp

Video bitrate, frame rate and resolution and H264 introduction

Video bitrate, frame rate and resolution exactly which one affects the sharpness of the movie Code rate: affect the volume, proportional to the volume: the larger the rate, the larger the volume, the smaller the rate, the smaller the volume. The bitrate is the number of data bits transmitted per unit of time when data

Use Rate-limit to limit traffic

1. Enable CEF in global mode: Router (config) # IP CEF 2. Define the standard or extended access list: Router (config) # access-List 2 permit 192.168.6.0 0.0.255 3. Perform rate-limit on the port to be restricted: Rounter (config-If) # rate-limit output access-group 2 128000 16000 16000 conform-Action transmit exceed-Action drop Rate-limit command format: #

Song Xing: the bounce rate may not be lower, the better.

People believe that the lower the bouncerate, the better, but as the old saying goes, the lower the bouncerate may not be as good as we expected. BounceRate is one of the basic metrics of website analysis. I believe everyone is familiar with it. Bouncerate seems to represent People believe that the lower the bounce rate, the better, but as the old saying goes, the lower the bounce rate may not be as good as

Video bitrate, which is linked to the difference between frame rate and resolution

Video bit rate, which frame rate and resolution affects the transparency of the filmRate: The amount, and proportional to the volume: a larger rate. Large size. A smaller speed. A smaller volume.The rate is the transmission of data bits per unit of time, in general, we use thousands per second in units Kbps. Sampling

Calculation method of Ethernet packet rate

We know that a gigabit port's wire-speed packet forwarding rate is 1.4881MPPS, The speed packet forwarding rate of the gigabit port is 0.14881MPPS, which is the international standard, but how is it obtained? The specific packets in the transmission process will be preceded by each package 64 (leader) preamble is a 64-byte packet, originally only 512 bit, but in the transmission process will actually have 5

What is the mouse refresh rate?

Mouse refresh rate is also called the mouse sampling frequency, refers to the mouse can collect and process the number of images per second. Refresh rate is also one of the important performance indicators of the mouse, that is, the mouse every second can be collected image data, generally "fps/s (frame/sec)" as a unit.   The significance of the concept of mouse refresh

Introduction of x264 Code Rate control method

Transferred from: http://www.bubuko.com/infodetail-471698.html1. X264 explicit support for a pass-rate control method is: ABR, CQP, CRF. The default method is CRF. The priority of these three methods is ABR > CQP > CRF.if (bitrate) Rc_method = ABR;else if (QP | | qp_constant) Rc_method = CQP;else Rc_method = CRF;Bitrate and QP do not have default values, once set they indicate to follow the corresponding code rate

accuracy (accuracy), accuracy (Precision), recall rate (Recall) and F1-measure

selected.As the evaluator you need to evaluate (evaluation) under his work First we can calculate the accuracy rate (accuracy), which is defined as: for a given test data set, the classifier correctly classifies the ratio of the number of samples to the total number of samples. That is, the loss function is a 0-1 loss when the accuracy rate on the test data set [1].This sounds a bit abstract, simply p

Website Optimization results Test experience from the analysis of site conversion rate of departure

How to judge if optimization is good or not? How to identify if the optimization is in place? Today I come to talk about my website optimization experience, in my opinion, site optimization is not only to see a site rankings and traffic, but should focus on the core of optimization, why do we want to optimize the site? Because we need to improve the conversion rate of the website, So is your site optimized to now improve the conversion

51 baud rate

The serial port of 51 chips can work in several different working modes. The working mode is set to use the scon register. The specific definitions of its bits are as follows:Sm0 SM1 SM2 Ren tb8 rb8 Ti riSm0 and SM1 are bits in the working mode of the serial port, so that the two can be set in four modes. Set the working mode of the serial port. When using the serial port for communication, a very important parameter is the baud rate. normal communic
