Accumulating evidence suggests that a history of diabetes may be involved in the occurrence of various types of cancer. However, the association of diabetes with the risk of brain tumors remains unclear. We identified relevant studies by performing a literature search of PubMed and EMBASE (through to 24 May 2012) and by searching the reference lists of(More)
The circuit and corresponding steady state vectors' relationship of single-phase PWM rectifier using IGBTs (Insulated Gate Bipolar Transistors) is analyzed, and the mathematic model and controller structure are presented, the PI regulators of the current and voltage loops are designed respectively. The method based on the Matlab/Simulink Blocks is used to(More)
The composing of high-frequency power wave trapper were introduced in this article, and a new method based on traditional correlation theory is presented in the test system. Cross-correlation functions of the two measured signals are directly computed and some properties about correlation and sine function are adopted to separate the part noise and useful(More)
