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
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
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

Leakage of PLC Ethernet modules of Mitsubishi Q Series added to the Energy Management System of Japan's North Ocean University
For the safety analysis of the Mitsubishi Q series PLC, refer to the previous article. This is a real case of the control device running on the public network. It is also a case that can be confirmed based on the title.In theory, if the PLC does not set a password, it can implement remote management operations through programm

Yehuda Shinar is a winning research expert. after 18 years of scientific research and practical experience, after studying more than cases from different cultures and backgrounds, he found a very meaningful common law-the mode of thinking. Sina was inspired by the Demand Class theory (hierarchy of needs) of the famous psychologist Abraham Maslow, and further developed a set of universally applicable pyramid-based "winner model 」.
His positive thinking rules have won praise from all walks of life
Microsoft has repeatedly declared that the upgrade of Windows 7 will save a lot of resources for enterprises. Today, green and environmental protection have become the focus of enterprises' attention, and energy conservation has to be considered. Recently, Mindteck, an embedded software development and consulting company, tested the power consumption of Windows 7 and XP in sleep, low usage, and high usage on multiple computers.
From the test results,
Android Bluetooth Low Energy (Android Low-power Bluetooth)
Android 4.3 (API Level 18) has introduced core functions of Bluetooth Low Energy (BLE, Low-power Bluetooth) and provided relevant APIs through which applications can scan devices and query services, characteristics (attribute feature) of a read/write device ). Compared with traditional Bluetooth, BLE can significantly reduce power consumption. This
Recently, when the ZigBee protocol was simulated in NS2. after the energy model was added, it was found that all nodes were green, and the changes in node color in the program were ineffective, you cannot add tags to a node. After carefully observing the source code, we found that the following two lines of the void mac802_15_4mac.cc line 919th: Recv (packet * P, Handler * h) function are in the p802_15_4mac.cc file:

"Potential Energy" Cultivation of project managers
I have heard that, as a project manager, I have to work in the company for at least two years and be at least thirty years old. I was still young and did not bother with these two points. But now, I understand it very well. It is difficult to coordinate resources horizontally because the company has a short working time and is not familiar with the personnel. If it is too old, it is not calm and prac
