This paper formulates and solves the problem of optimizing switching surfaces (SSs) in switching LPV (SLPV) controller design to further enhance the control performance. The conditions for the SLPV controller synthesis under fixed SSs are first presented, which involves a finite number of linear matrix inequalities. The SS design problem is then formulated as an optimization problem where the cost...
Device to Device (D2D) multicast communication is an effective method for local transmission. In this paper, a joint power and resource allocations scheme is proposed to maximize the number of accessed D2D groups while minimizing the total terminal transmission power for D2D underlay multicast communication. Since the derived optimization is a mixed integer nonlinear programming problem with high...
This paper proposes a novel Gain-Aware Uplink-Downlink(GAUD) jointly resource allocation scheme to maximize the Device-to-Device(D2D) throughput while guaranteeing Quality of Service (QoS) of cellular users. We formulate the global optimization problem as a mixed integer nonlinear programming problem and decompose it into three sub-problems. Firstly, a method of jointly uplink and downlink reuse mode...
With the ever-increasing demands for popular content sharing among humans, device-to-device (D2D) multicast communication, as a promising technology to support wireless services within a local area, is introduced in a 5G cellular network. However, the existing resource allocation approaches for D2D multicast communication usually consider only physical domain constraints but neglect social domain...
Fluorescence technique serves as a soft sensor with the ability to estimate the shape of emission and excitation spectrum and the information of concentrations of each fluorophore in multi-component fluorescent substances. Noise exist in each measurement inevitably. The impact of smoothing on parallel factor model of fluorescence emission excitation matrix is studied by compare nine methods. Smoothing...
This paper proposes an uncertainty modeling and robust controller design method for miniaturized 3 degrees-of-freedom OISs to deal with its product variabilities.

Crystalline Silicon solar cells that affected by potential induced degradation (PID) are investigated in recent years. PID has negative effects, especially power loss, on reliability and long-term performance of photovoltaic (PV) system. Then the law of modules with PID in the field is not published. In this paper, some significant conclusions were obtained through a large number of data analyzing...
A degradation of Si solar cells called PID has been confusing in recent years. This paper reveals that mechanism of PID occurs to Si solar cells at high bias voltage. ANSYS, a finite element software, is adopted to build a module model and the electric field distribution. Through derivation, interface leakage current between glass and EVA is given out. It is shown that sodium ions migrate to cells...
In this paper, a novel intent inference based dynamic obstacle avoidance method is described that is effective for both normal moving obstacles and maneuvering obstacles, therefore taking advantages of information from different sensors and electronic map. Unlike many of the methods discussed in literature our approach is based on inferring the intent of moving obstacles. It avoids the prediction...
In this paper, we deal with the problem of simultaneous design of state-feedback switching linear parameter-varying (LPV) controllers and switching surfaces for LPV plants to further improve the performance of the switching LPV controllers. The LPV plants that we consider have polynomially parameter-dependent state-space matrices. Using slack variable approach, we first propose a method to design...
This paper presents robust control of large-scale prototypes for miniaturized optical image stabilizers (OIS's) with product variations. Based on the conceptual design of a miniaturized lens-tilting OIS for mobile applications, large-scale 3-DOF prototypes are fabricated as a proof of concept. Variations in geometrical parameter of the lens platform are produced to mimic unavoidable product variations...
Pentaerythritol (PE) is a solid-solid phase change material with large latent heat. To improve its performance of thermal storage, nano-SiB6 particles were physically mixed into PE as nucleating agent with contents of 1 wt%, 3wt%, 5wt%, respectively. FTIR analysis was performed for pure PE, nano-SiB6 and the composites. The results show that there are no valence bonds between PE and nao-SiB6, and...
In this paper, a maneuver decision making method for autonomous vehicle in complex urban environment is studied. We decompose the decision making problem into three steps. The first step is for selecting the logical maneuvers, in the second step we remove the maneuvers which break the traffic rules. In the third step, Multiple Attribute Decision Making (MADM) methods such as Analytic Hierarchy Process...
