W-doped TiO2 with nanoporous structure was synthesized by a one-step low temperature hydrothermal method using TiOSO4 and (NH4)6H2W12O40•xH2O as titanium and tungsten sources. Structure, morphology, specific surface area and chemical state of samples were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM) and X-ray photoelectron spectroscopy (XPS). W-doped nanoporo...

In the application of multi-agent systems to real-world problems, agents often suffer from bounded rationality where agent reasoning is limited by 1) a lack of knowledge about choices, and 2) a lack of resources required for reasoning. To overcome the former, the agent uses sensing to refine its knowledge. However, sensing can also require limited resources, leading to inaccurate environment mo...

This paper focuses on the tracking and synchronization problems of hyperchaotic systems based on active backstepping method. The method consists of a recursive approach that interlaces the choice of a Lyapunov function with the design of feedback control. First, a nonlinear recursive active backstepping control vector is designed to track any desired trajectory in hyperchaotic Wang system. Furt...

Wireless monitoring has emerged in recent years as a promising technology that could greatly impact the field of structural monitoring and infrastructure asset management. This paper is a summary of research efforts that have resulted in the design of numerous wireless sensing unit prototypes explicitly intended for implementation in civil structures. Wireless sensing units integrate wireless c...

We provide the theoretical basis of calorimetry for a class active particles subject to thermal noise. Simulating AC-calorimetry, we numerically evaluate heat capacity run-and-tumble in double-well and periodic potentials, systems with flashing potential. Low-temperature Schottky-like peaks show role activity indicate shape transitions, while regimes negative appear at higher propulsion speeds....

Structural sensing, monitoring and control can benefit from wireless communication and embedded computing technologies in terms of installation cost and time. Our prior research has developed low-cost wireless sensing systems for structural monitoring. By incorporating an actuation signal generation module, the functionalities of wireless sensors can be extended to support structural actuation ...

A mobile robot system will typically have associated with it a number of sensing subsystems. If these sensing subsystems are \active", that is, using motion to aid in the sensing process 1, 2, 8, 9, 14], they will each be issuing motor requests related to the sensory processing algorithm that they are performing. In addition, the manipulatory portions of the robot system (i.e. those which uses ...
