Manning Publications, 2009年新书 Unit testing, done right, can mean the diff erence between a failed project and a successful one, between a maintainable code base and a code base that no one dares touch, and between getting home at 2 AM or getting hom

A wideband adaptive isolator for a UHF RFID reader with a minimum component count is introduced. The operation of the device is based on a reflection from a variable load, which is connected to a port of a hybrid coupler. The other ports are connecte
高清英文PDF版！.NET单元测试艺术（The Art of Unit Testing_with Examples in .NET）。《.NET单元测试艺术》针对这个重要主题展开讨论，引导读者从简单的测试开始，逐渐过渡到如何写出可维护、可读、可信赖的测试。同时，还涉及mock，stub和框架(如Typemock Isolator和Rhino Mocks)等高级主题，旨在帮助读者逐步掌握高级的测试模式和结构，高效地为遗留代码和甚至根本不可测试的代码编写测试。书中还讨论了测试数据库时需要的工具和其
Optocouplers have existed in various forms since the late 1960s and find use in many different applications. Because optocouplers suffer from a myriad of technical issues, the user community has been forced to remedy optocoupler quirks by adding ext
This guide will help you use Typemock Isolator. It is intended for coders who are familiar with NUnit or Visual Studio Unit Tests and Mock Objects in general. Typemock Isolator is a powerful tool that makes unit testing easy by isolating tested clas

A simplified ring cavity for achieving a unidirectional room temperature multi-wavelength erbium-doped fiber ring laser without optical isolator is demonstrated. The fiber ring cavity is built in such a way that the optical fields propagating in two
This paper presents the growth of cerium substituted YIG (CeiYIG) thin films on silica substrate.The large Faraday rotation coefficient and strong in-plane anisotropy were observed. The film is desirable for waveguide configuration isolator applicati
A waveguide optical isolator with a CeY2Fe5O12 guiding layer employing a nonreciprocal phase shift was studied. The isolation ratio of more than 12.2 dB was achieved at a wavelength of 1.55 μm.
Selective oxidation of an AlInAs layer was investigated for enhancement of magneto-optic effect in an optical isolator. Twelve times nonreciprocal phase shift enhancement was estimated from a measured AlInAs-oxide refractive index.
