The "decision-making support for power supply-side quotations and economic operation management system" originally planned by the company, under the influence of the national macro-control policy, as well as the current constraints on coal, electricity, oil, and transportation shortage, as a result, many power plant power generation costs have risen, and various power companies have doubts about whether to launch bidding in the electricity market, so

Project Background Shaoxing county is the first pilot city of Digital Urban Management in Zhejiang Province and the first county-level city in China. As the economy develops rapidly, the pace of urbanization accelerates, and the scale of the city expands and the degree of modernization continues to increase, the underground pipelines of the city, as an important urban infrastructure, are becoming increasingly large and intensive, the types of pipelines are becoming more and more complex. The pi

Introduction: In the Windows Phone 7.5 era, it is impossible for developers to obtain device power information due to API limitations. Fortunately, WP8 SDK has added support for this, in this way, we can get the percentage of remaining power in the application, and the remaining time. 1. What namespaces are required? What events are handled? Which attribute values are obtained? Two attributes are used: Battery. RemainingChargePercent: gets the percentage of remaining power from the phone. Batt

BatteryPower Supply Module knowledge point 1. Notice on lithium battery charging curve; 2. Combined with code understanding, the state machine transformation process in the charging process; 3. What is the voltage of the low-voltage prompt; 4. What are the boot voltage and boot current respectively, and the V of the low-power shutdown voltage; 5. The full grid voltage is divided into several grids, and the corresponding voltage range of each grid is a

Inflation is caused by the excessive amount of currency in circulation. From this perspective, the most intuitive indicator is M1 (money supply in narrow sense ). M1 includes cash in circulation and deposits of non-financial companies, which are money that may enter the circulation field at any time. M1 data is regularly published by the Central Bank and can be obtained by any investor through multiple channels. M1 is measured based on its growth rate

State transition equation: Set OPT (V', I) to indicate that CI is the maximum number of I-to n-1 drinks, calculate the maximum value of satisfaction in the total number of V' programs. The recursive formula should be: Opt (V', I) = max {K * Hi + OPT (V '-

The following is my summary of the basis of the mos and MOS driving circuit. I have referred to some materials, not all original. This includes the introduction, features, drivers, and application circuits of MOS tubes. When using MOS to design a switching power supply or motor drive circuit, most people will consider the mos on-resistance, maximum voltage, maximum current, and so on. Many people only consider these factors. Such a circuit may work, b

~ 1. Digital, analog, and power supply on the Board: From this figure, we can see that the analog and digital locations are completely separated, and finally each point is connected to the power source, which can prevent the mutual Crosstalk of the ground signal from affecting some sensitive components, as we all know, digital components have a higher Interference tolerance than analog components, while the noise on the digital ground is ge

Network Management technicians are both supply and demand in terms of market performance. Taking the weekly statistical results of Hongkou vocational Research Institute as an example, 22 Network Management technicians were recruited, with more than 240 candidates. The annual salary of Network Management technicians was 100,000, there are more and more people interested in this job. Chen, a recent college graduate, is very interested in this. He majore

5G technology, the power consumption and cost problems of far-reaching optical power supply are enough for it to drink a pot, 5g a pot 5G is getting closer and closer, but not all places have it, and it will not be abrupt. The first version that comes to people's eyes is not the fastest version of the technology. In reality, 5G is the first to show in a densely populated metropolis. Since 2020 or 2021, 5g has gradually become popular in the next ten
