"Jin pa/Chuang Fu Hui" is a combination of men's and entrepreneurial black Horse in China's first attention to create rich micro-strength organization, is currently the only one to focus on the Tao, tuition, doubts, the reform of the idea of collision platform and guide many entrepreneurs lighthouse.

It is not hard to tell from the extensive publicity of canon that the story of Canon began in 1933, precisely because it was founded in November 1933 by the "Institute of precision optics ...... In that year, as the "camera country" of the world, Germany had two major brands-Leica/Leica and Conway's/contax. Both companies are producing 35mm focal plane shutter cameras that represent the highest technical level at that time. In the early 1930 s, Le

An important and typical feature of this is that it is a shared broadcast medium. Packets sent or received will be uploaded or downloaded to each user of the same channel.FTTH (Fiber to the home) fiber to the householdEach user has a ont (optical network Terminator), and multiple users (typically less than 100) are connected to the same upper splitter (optical spli

Reference Price: Undecided Eyecam (eye camera) from eyeborg company sounds more like a technology than a real product, but it may provide some reference for the future development of smart glasses. It's actually a prosthetic eye with a wireless camera device, or a real "digital eye" that can send a photo video to a smartphone or computer. So, it gets the content of the angle is very similar to Google glasses, but the limitations are greater because the average user does not instal

The University of California, Santa Barbara (UCSB) has built a new research centre that could turn this idea into reality, according to a network of American physicists, which will work with the university's Gigabit Optical Ethernet Research Center (TOEC) to develop the technologies necessary for the next generation of Ethernet. Compared with today's most advanced networks, the next generation of Ethernet data transmission speed 1000 times times faster, and more efficient. The researchers hope t

of the Gbit. We have to use them in the 1-4X1 Gbit Ethernet pool (the performance of multiple network cards is aggregated into a single virtual network card). In the end, we have some newer sr2600 i7 Intel architecture servers that achieve a non-performance loss of up to ten Gbps bandwidth through fiber optics. The results of all of the above summaries are calculated based on such hardware conditions. English Original: GERGELY KALMAN, compile: @ old

-platform system. Up to now, it can support twenty or thirty kinds of CPUs. And the performance is stable, the cutting is very good, development and use are very easy. Many CPUs including the home appliance industry chip, have started to do the Linux platform transplant work. Porting is much faster than the Java development environment. That is, if you are developing a product with a Linux environment today, you will not have trouble changing CPUs in the future. At the same time, the structure o

Therefore, there is a metric representation between each of the sma

Convenient communication tools: Each drawing result can be modified and saved by the user according to their own intention, so it is particularly suitable for geometric communication, research and discussion. People call it the "dynamic Blackboard", which is the ideal tool for teachers to decorate t

Topological structure of the network Network topology unreasonable also can affect the speed. It includes the network cable erection is too long, networks redundant circuit. First, check the physical distance between the two network devices. Now enterprises, Internet cafes and other local area networks are mostly used in five types of twisted pair, while the effective dis

For:XDSL technology is to use digital technology to transform the existing analog telephone subscriber line, so that it can carry the broadband service. Low cost, easy to achieve, but the bandwidth and quality of the large difference.The biggest advantage of HFC networks is its wide frequency band and the ability to take advantage of cable

However, this is only part of the complete Picture: Spring is unique in using the IOC container as a complete solution to all architectural layers.Spring provides a unique data access abstraction, including a simple and efficient JDBC framework, which greatly i

Aplanatic point of single spherical refraction Recently, looking at the "Modern Optics Foundation" edited by Mr. Zhong Xihua, the first chapter introduces the aplanatic point and gives an example, which is the aplanatic point of the single spherical refraction that is to be discussed today. The position of the aplanatic point is given in the book, but the derivation process is not given. I tried to deduce it and put it here to make a note.Ziming (apl

today. As reading progresses, we will show you how virtual machines can help solve these important problems, so that you understand why virtual opportunities are an important part of modern computers. When we try to explain the concept of virtual machines, we must first understand the concept of "virtual". The word "virtual" is originally derived from optics, used to understand objects in a mirror. The object in the mirror is an actual physical ima

We've mapped out a right-angled triangle in the last blog post, although we are relative to the coordinates, we set the right triangle of the two waist is equal, but the actual display is not so, although by calculation, we can calculate the two waist of the triangle, so that they are in the coordinates of the scale, but the reality comes out equal , but when the graphics are more complicated, the workload is too big for us. So how do we do it? The answer is to use the transform matrix to give t

product may require the following key technologies and performance: high reliability, high-end port density, service quality assurance and other functions. The Fibre-optic Ethernet business is more cost-effective than other broadband access, but so far it has been used only in office buildings or in buildings where fibre optics have been laid. The strategic value of this new method of using Ethernet is not limited to cheap access. It can be used bo
