Although games is famous for its high interactivity, but in some special area of applications, such as educational games [1], the interactivity of games is still not enough. For example, the 3D objects in game scene cannot be cut off in real. This paper proposes a real-time 3D objects cutting technology in games, which can cut any arbitrary 3D objects at any angle into two parts. Applying with this...
Since the voltage blocking capability of a single insulated gate bipolar transistor (IGBT) is limited, series-connected IGBTs are used in power electronic converters to satisfy the requirements of high-power and high-voltage applications. However, due to the parameter differences of the series-connected IGBTs, it is difficult to ensure an equal voltage sharing between the devices during both transient...
Since Volker Strassen proposed a recursive matrix multiplication algorithm reducing the time complexity to n2.81 in 1968, many scholars have done a lot of research on this basis. In recent years, researchers have proposed using computer algorithms to solve fast matrix multiplication problem. They have found Strassen's algorithm or other algorithms that have the same time complexity as Strassen algorithm...
Wafer level packaging is an important development trend for IC package design. The fan-out wafer level package discussed here has the flip chip form which uses thin-film redistribute then uses solder bump to connect the package to the printed wiring board directly. Liquid compound was used for the encapsulation process. Comparing with wire-bond BGA, the fan-out wafer level package has better electric...
Aiming at a complicated coupling and non-linear brushless DC motor (BLDCM) servo system, the conventional algorithms have many disadvantages, such as less precision, lower speed response. Taking the mechanical characteristics of BLDCM into consideration, an improved particle swarm optimization algorithm is presented in this paper, which is applied in the speed control of the Brushless DC Motor (BLDCM)...
In this paper, an observer-based robust adaptive fuzzy sliding mode controller (RAFSMC) for an unknown nonlinear dynamical system with dead-zone input is presented. First, the fuzzy models are used to estimate the unknown function of the nonlinear dynamical system. Next, an observer is employed to estimate the tracking error. By the strictly-positive-real (SPR) Lyapunov stability theorem, it is shown...
