From the 4 major laws of thermodynamics, the following facts can be drawn:1) class 1th and category 2nd perpetual motive cannot exist; (1th, 2nd Law)2) Non-equilibrium, the total existence of energy exchange between non-isolated systems; (No. 0 law)We can think of life as a system a, and the surrounding environment can be seen as another system E. There are the following facts:1) A and e are connected, there is a heat exchange between A and E;2) The t

Of course, after years of frenzied growth, the industry is now mired in a stalemate to shuffle the trap. In this dilemma, there must be many enterprises affected by this impact and the vitality of the big injury, or even bankruptcy, of course, there will be many enterprises to get out of the h

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

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

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

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
A wireless sensor network is a multi-hop self-organizing network system formed by a large number of low-cost micro-sensor nodes deployed in the monitoring area through wireless communication, the purpose is to collaboratively perceive, collect, and process event information in the coverage area and send it to the observer. Due to limited node energy and difficult to supplement, the primary design goal of wireless sensor networks is the efficient use o

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
