Virtual Machine technology applies the concept of virtualization to an entire machine, circumventing real machine compatibility constraints and hardware resource constraints to enable a higher degree of software portability and flexibility. Virtual machines are rapidly becoming an essential element in computer system design. They provide system security, flexibility, cross-plat...(展开全部)

Many scientists and inventors contributed to the understanding of robotics and their development in the modern age. Modern Robotics presents succinct biographies of the men and women who were and are the leaders in bringing about this change through research and new technologies. From Jacques de Vaucanson to Grey Walter to Joseph Engelberger, here is a lively introduction to th...(展开全部)

While compilers for high-level programming languages are large complex software systems, they have particular characteristics that differentiate them from other software systems. Their functionality is almost completely well-defined – ideally there exist complete precise descriptions of the source and target languages, while additional descriptions of the interfaces to the oper...(展开全部)

This best-selling book employs a theoretical, practical, multidisciplinary approach to provide introductory users with a broad understanding of modern electric power. The scope of the book reflects the rapid changes that have occurred in power technology over the past few years–allowing the entrance of power electronics into every facet of industrial drives, and expanding the f...(展开全部)

在准备本书第6版时，我想将一些对电力系统有较大影响的新内容介绍给大家，其中有以下5部分内容。 第13章、12.23～12.26节介绍了双馈感应电机的原理与特性。该电机的调速可通过在定子加固定频率交流电，而在转子通入可变频率交流电来实现，故名为“双馈”。双馈电机原来用作变速电动机来驱动大型水泵等负载，现在，该电机在风力发电中作为双馈发电动机使用。由于风力发电的重要性，有必要在本书中介绍这种特殊的电机。 第21章、21.45～21.51节对PWM的相关内容作了重要的修改，增加了新的内容及图片。 第23章介绍了几种电动机调速的电子控制方法。23.31～23.40节特别介绍了直接转矩控制（DTC）方法，与应用PWM及矢量控制方法不用，DTC使用了砰砰控制法，其对速度及转矩的控制与其他方法不同，该章根据感应电机原理，对此做了直观的分析。 第24章、24...(展开全部)
