In the cloud computing model, a cluster of physical computers hosts an environment that provides shared services and offers the flexibility to easily add, remove, and expand virtual servers and applications. Cloud options range from public services,
Abstruct-A phase-lock loop occasionally will take a long time to settle to equilibrium. Phase dwells at a large error for a prolonged in- terval. This phenomenon has been dubbed “hangup.” The periodic nature of phase detectors is responsible fo r ha
An 840-GHz Schottky diode detector is integrated with an analog lock-in amplifier in 130-nm bulk CMOS. The integrated lock-in amplifier can support a modulation frequency of up to 10MHz with a gain of 54dB, a dynamic range of 42dB, and an input refe

Summary Linux in Action is a task-based tutorial that will give you the skills and deep understanding you need to administer a Linux-based system. This hands-on book guides you through 12 real-world projects so you can practice as you learn. Each ch
关于阻塞主线程
join的错误用法
Thread.join() 作用为阻塞主线程,即在子线程未返回的时候,主线程等待其返回然后再继续执行.
join不能与start在循环里连用
以下为错误代码,代码创建了5个线程,然后用一个循环激活线程,激活之后令其阻塞主线程.
threads = [Thread() for i in range(5)]
for thread in threads:
thread.start()
thread.join()
执行过程:
1. 第一次循环中,主线程通过
We report experimental progress in weakening the frequency difference lock-in phenomenon in a Y-shaped cavity dual-frequency laser. A cube coil pair is chosen to provide a uniform magnetic field for tunability and uniformity of magnetic field strengt
In this paper, an optical system for in-plane remote displacement measurement is brought forward. The remarkable characteristic of this optical system is to use a big aperture lens to focus the waists of two Gauss beams on a scatter which have been e
In ring laser gyros (RLGs), dynamic lock-in, which results from information loss in the lock-in region, occurs when a constant sine bias is introduced. However, sampling some signals in the lock-in region for a particular duration allows the retrieva
