Data analysis expressions (DAX) is the formula language of Power Pivot. Learning the DAX language is key to empower Excel users so they can take advantage of these new Business Intelligence (BI) capabilities. This volume clearly explains the concepts of Power Pivot while at the same time offering hands-on practice to engage the reader and help new knowledge stick

VITA 62-2016 英文原版标准，带目录。 VITA 62 defines both the mechanical and electrical requirements for COTS modules intended for creating modular power supplies. The primary focus is to support [VITA 46.0] and [VITA 65] systems with off the shelf modules that are compatible with the VPX specifications. The embedded market has focused primarily on the need to standardize the use of COTS processing add-in modules as part of the VPX suite of standards. Before this standard system designers treated the power supply as a necessary evil, which is often an afterthought. Modular power supply suppliers provided ad hoc solutions that system developers must implement. Providing power for these systems had historically been left up the module vendor, requiring them to define what has, at times, been seen as a form of “black art.” This standard, however, defines a set of rules by which industry power supply vendors can build COTS products, for VPX systems, that will fit into VITA 62 compatible backplanes. Consequently, system developers can have multiple vendors for power supply modules. At this time the focus of this standard is to define modules for VPX systems. In the future this standard may also be extended into other form factors. As part of the work to create VITA 62, a new connector system has been defined, optimized for the needs of VITA 62. This connector mechanically fits within the envelope defined in [VITA 46.0] for 3U and 6U Plug-In modules. This will facilitate the production of backplanes and allow system designers to define where and how many power supply modules are to be used within any given system.

循序渐进学习Power Builder 6.0，这东西现在不好找了！

Power electronics, which is a rapidly growing area in terms of research and applications, uses modern electronics technology to convert electric power from one form to another, such as ac-dc, dc-dc, dc-ac, and ac-ac with a variable output magnitude and frequency. It has many applications in our every day life such as air-conditioners, electric cars, sub-way trains, motor drives, renewable energy sources and power supplies for computers. This book covers all aspects of switching devices, converter circuit topologies, control techniques, analytical methods and some examples of their applications.
