Hall effect
When an electric metal or semiconductor wafer is placed vertically in a magnetic field, the two ends of the wafer produce a potential difference, which is called Hall effect. The potential difference between the two ends is called Hall potential, and its expression isUH = K · Ia · B/d
K is the
. If you have a master's degree in work for five or six years, each has an annual salary of about. Marvell, this semiconductor company has developed too fast over the past few years. It has acquired an Intel hardware department and a wireless chip Department of UT. By the way, the founder of Marvell is a Chinese Indonesian girl and a Shanghai girl, a strong man. They really give a long face to the Chinese. The businesses inside can be queried on the
improve the performance of parallel computer systems in the application of the processor. At this time, Illinois University and Burroughs began to implement the Illiac IV program to develop a 64-cpu simd host system, it involves many research topics including hardware technology, architecture, I/O devices, operating systems, programming languages, and applications. However, when a scaled-down prototype system (with only 16 CPUs) was launched in 1975, the entire computer industry had changed dra

output power, which cannot meet the processing needs. With the development of more reliable semiconductor pump solid technology and more reliable third-harmonic mechanism, the situation has changed. The new third-harmonic semiconductor pumped solid-state laser has become a competitor of the laser. The energy density level is equivalent, but the repetition frequency is higher, and the beam quality is better
Since the invention of the transistor in human 1947span> years, more than 50 years of semiconductor technology experienced silicon transistors, integrated circuits, VLSI, very large scale integrated circuits and other generations, the rapid development of other industries are not. Semiconductor technology has a wide impact on society as a whole, so it is called "the seed of industry". CPU refers to the comp
... Please let Mr. Huang share the story with us.
Huang Renxun: Graphics chips can also be applied to all compute-intensive applications, from the computational fluid dynamics that people try to simulate how air flows through cars, to the molecular dynamics that attempt to simulate a virus. Therefore, the application of GPUs (graphic processing unit) Parallel operation Architecture is absolutely amazing.
Forbes: At present, the graphics business has accounted for the Nvida company's revenue s
Matrix Revolution-Understanding matricesThe linear algebra course, whether you start from the determinant or directly from the matrix, is riddled with inexplicable beginnings. For example, in the national General Engineering Department of teaching the most widely used in Tongji linear algebra textbook (now to the fourth edition), one to introduce the reverse number of this "unprecedented, no one," the eccentric concept, and then use the reverse number

On the Internet to see an article, looked after the feeling quite deep. He tells the nature of linear algebra, and intuitively describes linear spaces, vectors, and matrices. The linear algebra course, whether you start from the determinant or directly from the matrix, is riddled with inexplicable beginnings. For example, in the national General Engineering Department of teaching the most widely used in Tongji linear algebra textbook (now to the four

Problems encountered and solutions:
The problem is that the code on the
current activity is paused and the previous activity is recovering, the suspended activity will no longer receive input from the user or execute any code and calls
onStop(): This callback method is called when activity is no longer a visual state
onDestroy(): This method is called before the activity is destroyed by the system
