在本课中，我们要用一个按键来实现跑马灯的 10 级调速。这又会涉及到键的去抖的问 题。  本课的试验结果是，每按一次按键，跑马速度就降低一级，共 10 级。  这里我们又增加了一个变量 speedlever，来保存当前的速度档次。  在按键里的处理中，多了当前档次的延时值的设置。  请看程序：  ―― ...

LED 一般是恒流操作的，如何改变 LED 的亮度呢？答案就是 PWM 控制。在一定的 频率的方波中，调整高电平和低电平的占空比，即可实现。比如我们用低电平点亮一个 LED 灯，我们假设把一个频率周期分为 10 个时间等份，如果方波中的高低电平占空比是 9：1， 这是就是一个比较暗的亮度，如果方波中高低电平占空比是 10：0，这时 ...

Reconstruction- and example-based super-resolution (SR) methods are promising for restoring a high-resolution (HR) image from low-resolution (LR) image(s). Under large magnification, reconstruction-based methods usually fail to hallucinate visual details while example-based methods sometimes introdu ...

在微电网调度过程中综合考虑经济、环境、蓄电池的 循环电量，建立多目标优化数学模型。针对传统多目标粒子 群算法(multi-objective particle swarm optimization，MOPSO) 的不足，提出引入模糊聚类分析的多目标粒子群算法 (multi-objective particle swarm optimization algorithm based on fuzzy clustering，FCMOPSO)，在 ...

New applications such as video conferencing, video on demand, multi- media transcoders, Voice-over-IP (VoIP), intrusion detection, distributed collaboration, and intranet security require advanced functionality from networks beyond simple forwarding congestion control techniques. 

Emerging technologies such as WiFi and WiMAX are profoundly changing the landscape of wireless broadband.  As  we evolve into future generation wireless networks, a primary challenge is the support of high data rate, integrated multi- media type traffic over a unified platform. Due to its ...

Employing multiple transmit and receive antennas, namely using multi-input multi-output (MIMO) systems, has proven to be a major breakthrough in providing reliable wireless communication links. Since their invention in the mid-1990s, transmit diversity, achieved through space-time coding, and spatia ...

Today’s wireless services have come a long way since the roll out of the conventional voice-centric cellular systems. The demand for wireless access in voice and high rate data multi-media applications has been increasing. New generation wireless communication systems are aimed at accommodating thi ...
