With the rise of the new generation of data center construction, with the increasing density of servers in the enterprise room, the amount of power consumption and heat dissipation is becoming the focus of enterprise IT administrators, the power consumed by the data center and the power consumption to cool these converted into heat have reached an increasing level. The huge consumption of electricity brings about all kinds of serious problems, the huge cost of electricity will increase the overa
Energy Saving Click to open the topic Time limit: Ms | Memory limit: 65535 KB Difficulty: 5 description Dr.kong designed robots are getting smarter. Recently, the municipal company handed over a task to the city, starting 5:00 every day, it was responsible for shutting down all the street lights on the right side of ZK Avenue. Every 5:00, he will be next to a street lamp on ZK Avenue, then he starts to turn off the light. Each lamp has a certain pow
Title Description Description On Mars planet, each Mars person carries a string of energy necklaces. There are n energy beads on the necklace. The energy bead is a bead with a head mark and a tail marker, which corresponds to a positive integer. Also, for two adjacent beads, the tail mark of the previous bead must be equal to the head mark of the latter bead. Bec
The first thought of trembling people in the cold wave was heating, but the cost of heating forced the less wealthy people to adopt a "green" heating method. This is exactly the energy-saving and money-saving skills that Mr. Weaver, executive director of the New York State Cornell society, taught to local people in poor conditions at his recent workshops. Heating and air conditioners account for 42% of household e
1-3-2. Calculation of energy storage inductance of inverted series Switching Power SupplyThe calculation method of the energy storage inductance of the inverted series switching power supply is basically the same as that of the previous "calculation of the energy storage filter inductance of the tandem Switching Power Supply". The value of the

As long as you put different energy crystals in a specific way, you can generate a huge amount of energy. The cube of
Energy efficiency has recently received a great deal of attention. Some people think this is a good "green" thing. Some people understand that this can achieve great financial benefits. But this is a more urgent thing for people in the storage and network industries. We are on the verge of an energy crisis. This crisis will fundamentally affect the lives of our professionals. Consider these questions: • A
Do not be with the people who consume you, because the future is not belong to the rich people do not belong to no money, is a positive energy people!To love a person who gives you positive energy. Everyone's life is the same, in a closer look is a fragment, far from the long river of time looking for happiness, looking for all things that can make themselves happy: health, calm, material, honor, achievemen
TheArticleIt refers to the ability of people to resist the temptation of food. The basic argument is that people's mental energy is similar to physical fitness, and there is a limit that will be consumed. If you continue to watch food when you are hungry and your willpower (mental energy) is exhausted, you will surrender. However, from experience, the mental energy
With the rapid development of information, data center as the core node of the network, strong support for the operation of the network, data center construction has greatly increased the attention. Data center in the construction process encountered in the energy consumption, green and other issues gradually by IT managers and the solution provider's attention. With the rapid development of network demand, many investors do not hesitate to build more
The broadband access network in China is developing very rapidly. So I have studied the detailed solutions for the broadband access network, and I will share them with you here, hoping to help you. The design of the network emission reduction scheme should be combined with the evaluation of Total Cost of Ownership. The Cost reduction scheme with high economic feasibility is the preferred solution. From the perspective of carbon emissions in the life cycle of communication products, Huawei has ma
Because the energy of the voice signal changes over time, the Energy Difference Between the voice and the voiced voice is quite significant. Therefore, the short-term energy and short-term average amplitude can be analyzed to describe the speech feature transformation. Defines the short-term average energy E of a voice
1-2-3. Calculation of energy storage filter inductance of tandem Switching Power SupplyFrom the above analysis, we can see that the output voltage of the tandem switch power supply is related to the duty cycle D of the control switch and the energy storage inductance L, because the energy storage inductance L determines the current rise rate (DI/dt), that is, the
Bkjia.com comprehensive report: energy saving and consumption reduction have always been the goal of the IT industry. This article describes the "package-by-package Power Control" Method Used in wlan ap products to achieve energy conservation and emission reduction goals and other benefits. 1. Analysis of "wireless packet transmission" In WLAN and Other Wireless RF systems, various information and packets a
Document directory Introduction Time management problems Energy Management Practical solutions Introduction I have known time management for a long time. It was probably because I used to read "Seven Habits of high-performance people" and "how to control my time and Life", but I started to think about it. Unfortunately, after graduation, I have never had the necessary skills, and I am working very efficiently. However, I feel that I am tired o
From June 1 onwards, China's network security work has a basic legal framework, for the network also has more legal constraints, China's information security industry into a new era. "The People's Republic of China Network security Law" further improve the personal information protection rules, in the future, the two strong competition, uncompromising embarrassing situation or can be avoided. Data center modularity: Taking into account safety and energy
PrefaceIn the 802.11 major releases, a total of four energy-saving models were defined, and in the previous document we introduced the most basic PSM mode and some details on how it works. Since PSM was designed under the initial 802.11 protocol, it was designed with a more conservative design to ensure the most stable operational requirements. In the later 802.11 new releases, there were other energy-savin
I have made many attempts to learn more about how to test the energy efficiency of switches in the LAN. Can not clearly handle their own needs, so in the following article, there should be a satisfactory harvest. Many network equipment manufacturers today promise that their networks and switching devices are energy-saving, but few vendors can prove their actual use. Therefore, enterprise users must test the
