Video streaming over HTTP is becoming the de facto dominating paradigm for today's video applications. HTTP as an over-the-top (OTT) protocol has been leveraged for quality video traversal over the Internet. High user-received quality-of-experience (QoE) is driven not only by the new technology, but also by a wide range of user demands. Given the limitation of a traditional TCP/IP network for supporting...
Aiming at the agile turn of over-the-shoulder launched air-to-air missile based on aerodynamic/direct force, this paper establishes the mathematical model of attitude control, designs the agile turn attitude control law based on second-order sliding mode control in the pitching plane and uses Matlab software for simulation. Compared with the conventional sliding mode control law, results show that...
Instantaneous low delay on-demand video streaming with a very low start up and channel switching delay is highly desirable for users. The dominant over-the-top (OTT) solutions like DASH, which is based on HTTP and/or WebSocket, suffer from a slow start of the underlying TCP transport while the typical coding structure of the DASH content introduces additional delays. In this work, we address these...
This paper presents a wide tuning rang mm-wave VCO (voltage controlled oscillator) fabricated in IBM 90-nm CMOS technology. The VCO can be tuned from 31.4 GHz to 42.2 GHz and utilizes a differential tuning mechanism based on varactors and switched capacitors. A switched current source is used to improve the performance of the VCO when an MIM (metal-insulated-metal) capacitor is switched in the LC...
A sliding-mode variable structure control algorithm with integral compensation was presented for the electromechanical servo tracking system. It contains the disturbance and the plant parameter variation. To obtain the optimal sliding mode, the switching function is determined by reaching condition. The integral gain and control function are obtained by quadratic optimization. An asymptotic state...
