In this paper, we consider the problem of vehicular positioning enhancement with emerging connected vehicles (CV) technologies. In order to actually describe the scenario, the Interacting Multiple Model (IMM) filter is used for depicting varies of observation models. A CV-enhanced IMM filtering approach is proposed to locate a vehicle by data fusion from both coarse GPS data and the Doppler frequency shifts (DFS) measured from dedicated short-range communications (DSRC) radio signals. Simulation results state the effectiveness of the proposed approach.

Considering the under-actuated characteristic of the carangiform robotic fish whose forward movement and turning are carried out by its single caudal fin, this paper investigates its shortest path planning problem subjected to the terminal constrains. First, a simplified kinematics model is proposed in view of its locomotion characteristic. With this model, the shortest path planning is transformed into the shortest time optimal control problem and the maximum principle is employed to obtain the necessary condition. Furthermore, based on the analysis on the relationship between the length of all feasible paths and the terminal condition, the sufficient and necessary conditions are derived for the shortest path under any terminal constrains. Finally, a program developed with Matlab verifies the effectiveness of the proposed results.

This paper proposes a novel transverse flux permanent magnet motor (TFPMM) with double-C stator hoops. The proposed TFPMM carries significantly increased power density due to higher coefficient of utilization of the volume compared with the traditional double-side counterparts. The topology, principle and parametric calculation of the TFPMM are described elaborately. The magnetic field and characteristics analysis are conducted by three-dimensional finite element method (3D FEM) including flux density, EMF and winding inductance, and cogging torque are obtained to verify the feasibility of proposed TFPMM design. The mechanism of cogging torque of the proposed double-C stator hoops TFPMM is also analyzed. The results of transient simulation of power density well align with the theoretical analysis, which confirm that the power density is significantly increased due to its higher volumetric utilization ratio. © 2014 IEEE.

The Z-source neutral point clamped (NPC) inverters can realize buck-boost energy conversion with all satisfying advantages of the three-level inverters. A significant problem related to this topology is the fluctuation of the neutral-point potential (NP). However, the previous modulation techniques for this topology cannot achieve the considerate stable voltage. In this paper, based on the analysis of the relationship among the shoot-through duty cycle and the NP voltage, the average NP current, switching frequency capacitor value, a new feed-forward compensator by modifying the shoot-through duty cycle which can improve to balance the NP voltage balancing is proposed. Meanwhile, in consideration of a low voltage gain caused by the NP voltage balance method, a new control method based on a maximum constant boost control method is proposed, which brings the benefits in both high voltage gain and low-frequency ripple. The considerate stable NP voltage and the high voltage gain have been proven in simulation and through experimental results from a prototype converter. © 2014 IEEE.

Hybrid systems with memory are dynamical systems exhibiting both hybrid and delay phenomena. We present a general modelling framework for such systems using hybrid functional inclusions, whose generalized solutions are defined on hybrid time domains and evolve in the phase space of hybrid memory arcs equipped with the graphical convergence topology. We prove a general existence result based on some basic conditions on the data of hybrid systems. We further establish sufficient conditions for the stability analysis of hybrid systems with memory using Lyapunov-Razumikhin (L-R) functions. We demonstrate the stability results on a general nonlinear system with switching dynamics and state jumps. © IFAC.

A cluster-based network topology enables the efficient utilization of the limited energy resources in network;based on multi-hop clustering model, the unequal routing protocol can lead to uniform energy dissipation among the cluster head and achieves some improvement on the network lifetime. However, the bottleneck zone, where the energy of the nodes closer to the Sink is depleted quickly, still limits the network lifetime in some cases;especially the collecting data can't be compressed. In this paper, a Hybrid transmitting protocol for Unequal Cluster-based Routing WSN(H-UCR) was proposed, which combined single-hop and multi-hop transmission is implemented to balance the energy dissipation among the entire network. Simulation results demonstrate that our proposed approach is effective in balancing the energy consumption and prolonging the network lifetime. © (2014) Trans Tech Publications, Switzerland.

A cluster-based network topology can increase the scalability and lifetime. However, the area around the Sink node forms a bottleneck zone due to heavy traffic-flow, which limits the network lifetime in WSN, the energy of the nodes closer to the sink node is depleted very quickly and the network die early, so it is important to ensure that the network energy dissipation is balanced. In this paper, an unequal fan-shaped clustering (UFC) model was proposed, which can lead to more uniform energy dissipation among the entire network, thus increasing network lifetime. The results show that UFC can lead to more uniform energy dissipation in a homogeneous network and prolong network lifetime. © (2014) Trans Tech Publications, Switzerland.

Continuous monitoring of variations in blood flow is vital in assessing the status of microvascular and macrovascular beds for a wide range of clinical and research scenarios. Although a variety of techniques exist, most require complete immobilization of the subject, thereby limiting their utility to hospital or clinical settings. Those that can be rendered in wearable formats suffer from limited accuracy, motion artifacts, and other shortcomings that follow from an inability to achieve intimate, noninvasive mechanical linkage of sensors with the surface of the skin. We introduce an ultrathin, soft, skin-conforming sensor technology that offers advanced capabilities in continuous and precise blood flow mapping. Systematic work establishes a set of experimental procedures and theoretical models for quantitative measurements and guidelines in design and operation. Experimental studies on human subjects, including validation with measurements performed using state-of-the-art clinical techniques, demonstrate sensitive and accurate assessment of both macrovascular and microvascular flow under a range of physiological conditions. Refined operational modes eliminate long-term drifts and reduce power consumption, thereby providing steps toward the use of this technology for continuous monitoring during daily activities. © 2015 The Authors, some rights reserved.
