Through virtualization, a plurality of servers can be simulated on a single physical machine. The sharing of hardware resources of one physical machine by multiple virtual servers greatly improves resource utilization. The key to virtualization is how to handle the allocation and management of hardware resources among competing virtual machines. One type of hardware resource that has not been fully...
The traditional control theory is based on the assumption model. which leads to the subjectivity weaknesses in control process. In this paper, we introduced a model-free and data-driven control method — unfalsified control method and described its basic theory in details. This algorithm is applied to the straight line inverted pendulum system. It has simple controller and does not depend on the system...
We propose and demonstrate a wavelength re-modulated WDM-PON implemented by reflective semiconductor optical amplifiers (RSOAs) using 4B/5B and 4B/6B line codes, which have higher coding efficiency than Manchester code, for downstream modulation. The experimental results show that 4B/5B and 4B/6B line codes allow using unsaturated RSOAs as upstream re-modulator, thus improving power budget compared...
This paper presents a compact triple and wide band RF antenna with ultra-thin size based on PIFA structure, which covers the GSM/DCS/RFID/TD-SCDMA/WLAN services at the same time. The proposed RF antenna occupies a total volume of only 32×25×3.4mm3. A novel inverted “Z” shape slot structure is used for the first time in antenna design, it is proved to be more suitable for overall network matching of...
A viable and affordable real-time and online control technology named remote production dashboard (RPD) for discrete manufacturing process based on knowledge service is proposed. Firstly, the basic framework of RPD consisted of production environment layer, data process layer, knowledge service layer and man-machine interaction layer is constructed. Secondly, the principles of two key technologies...
This paper has investigated the approaches of automotive 3-D styling based on the hand sketching with Wacom?? Cintiq 21UX digital screen. By the analysis of curve modeling tools for the current CAD systems used broadly in automotive industry, the easier, more intuitive and more convenient 3-D styling approaches are discussed. The stylist can change the curves with modified strokes during the sketching...
