　JMS是用于和面向消息的中间件相互通信的应用程序接口。它既支持点对点(point-to-point)的域，又支持发布/订阅(publish/subscribe)类型的域，并且提供对下列类型的支持：经认可的消息传递,事务型消息的传递，一致性消息和具有持久性的订阅者支持。JMS还提供了另一种方式来对您的应用与旧的后台系统相集成。 ...

This book is about multipoint cooperative communication, a key technology to overcome the long-standing problem of limited transmission rate caused by inter- point interference. However, the multipoint cooperative communication is not an isolated technology. Instead, it covers a vast range of resear ...

逆变器作为光伏阵列和电网接口的主要设备，它的性能决定着整个光伏发电系统的性能。为了将光伏阵列产生的电能最大限度地馈入电网，并提高其运行的稳定度、可靠性和精确度，必须对并网逆变器的主电路拓扑选择、滤波器参数设计及其控制策略选取等进行深入研究。 论文首先分析了光伏发电的国内外发展现状和应用前景，对光伏并 ...

Many CAD users dismiss schematic capture as a necessary evil in the process of creating\r\nPCB layout but we have always disputed this point of view. With PCB layout now offering\r\nautomation of both component placement and track routing, getting the des

Abstract: IC switches and multiplexers are proliferating, thanks to near-continual progress in lowering the supply voltage,incorporating fault-protected inputs, clamping the output voltage, and reducing the switch resistances. The latest of these advancesis the inclusion of precision resistors to ...

This paper presents a space vector modulation(SVM)-based switching strategy for a three-level neutral point clamped (NPC) converter that is adapted as a STATCOM.

  The MAX2691 low-noise amplifier (LNA) is designed forGPS L2 applications. Designed in Maxim’s advancedSiGe process, the device achieves high gain andlow noise figure while maximizing the input-referred 1dBcompression point and the 3rd-order intercept point. TheMAX2691 provides a hig ...

  Sensors for pressure, load, temperature, acceleration andmany other physical quantities often take the form of aWheatstone bridge. These sensors can be extremely linearand stable over time and temperature. However, mostthings in nature are only linear if you don’t bend them toomuch. ...
