This article presents robust control of the mobile inverted pendulum system(MIPS) whose structure is a combination of a wheeled mobile robot and an inverted pendulum with two arms. The MIPS navigates on the horizontal plane while balancing the pendulum. Control of the MIPS is difficult since the system is non-holonomic and nonlinear so that simple linear(More)
In a trust network, two users who are connected by a trust relationship tend to have similar interests. Based on this observation, existing trust-aware recommendation methods predict ratings for a target user on unseen items by referencing to ratings of those users who are reachable from the target user in the forward direction of trustor-trustee(More)
During T cell activation, mitochondrial content increases to meet the high energy demand of rapid cell proliferation. With this increase, the level of reactive oxygen species (ROS) also increases and causes the rapid apoptotic death of activated cells, thereby facilitating T cell homeostasis. Nicotinamide (NAM) has previously been shown to enhance(More)
This article presents the application of mobile inverted pendulum systems to design Boxingbots for robot boxing games. Intelligent control algorithms are applied to the Boxingbot whose structure is the mobile inverted pendulum robot with arms. The Boxingbot has the combined structure of a mobile robot and an inverted pendulum system. The reference(More)
In communication channel of a tele-operation control task, there always exists a time-delay problem which causes poor performance and even instability of the system. To overcome the time-delay problem, in this paper, the Smith predictor configuration is considered. The Smith predictor can stabilize the system by taking the time delay term out of the(More)
In this paper, we present a novel approach to computing link-based similarities among objects accurately. We discuss the problems with previous link-based similarity measures and propose a novel approach that does not suffer from these problems. In the proposed approach, each target object is represented by a vector. The elements of the vector denote all(More)
As PCB components become more complex and smaller, the conventional inspection method using traditional ICT and function test show their limitations in application. On the contrary, the automatic optical mspection(AOI) gradually becomes the alternative in the PCB assembly line. In Particular, the PCB inspection machines need more reliable and flexible(More)
