Since the current rate control schemes in H.264 do not present the capability of efficient GOP-level bit allocation, the video quality varies greatly for sequences with the scene change or the scene complexity varying from one GOP to another. To overcome the limitation, we propose a novel rate control scheme based on incremental PID algorithm. The incremental PID algorithm is introduced to minimize video quality variations in GOP-level bit allocation. Extensive simulation results show that the proposed rate control scheme, without expensive computational complexity added, decreases the average video quality variations by 15.07%.

There is growing interest in accessing, relating, and combining data from multiple sources on the Web. Today, web users access the web through two dominant interfaces: clicking on hyperlinks (browsing) and searching via keyword queries (crawling). This process is often time-consuming and unsatisfactory because of the many inaccurate and irrelevant results that are returned. Better support is needed for expressing one's information requirements and dealing in more structured and systematic ways with one's search results. This paper presents ALII, our proposal for providing this support. ALII is an Active Logic based framework for Information integration, which can utilize a compact context representation and constructs a hierarchy model of query and web pages. The ALII project aims developing methods and tools for a model based, semantic integration of information sources on web pages.

Signal via transition is inevitable in backplane multi-layer board for high density routing. And a significant simultaneous switching noise (SSN) coupling to a signal occurs through the signal via transition. In this paper, we present suppression method of the SSN noise coupling caused by via transition in multi-layer backplane board using electromagnetic bandgap (EBG) structure. EBG structures are vertically located around a signal via to provide the low power/ground impedance area. The low power/ground impedance area suppresses the noise propagation and reduces the SSN noise coupling. It is shown that, within the stopband, the power/ground impedance at the position of the signal via with EBG structures is free from the power/ground planes cavity resonance, and the SSN coupling in single-ended and differential signaling is suppressed.
The control parameters of the grid-forming (GFM) inverter-based resources (IBRs) directly impact power system dynamics. The primary control requires the GFM inverter to balance generation and load. It is also preferre...
