In this manuscript, we describe a class of hybrid electrochromic materials utilizing polythiophenes and tin-doped indium oxide (ITO) nanoparticles that independently modulate visible and near-infrared (NIR) light. By altering the voltage applied across electrodes modified with these composite materials, the electrodes can be repeatedly switched between three distinct modes of operation. These “...

The development of innovative adaptive structures on UAVs (and UUVs), such as morphing wings, can potentially reduce system complexity by eliminating control surfaces and their auxiliary equipment. This technology has the potential of allowing a UAV to adapt to different mission requirements or executing a particular mission more effectively. The first part of the paper deals with a review of m...

Powder metallurgic giant magnetostrictive composite materials (GMM) which are special kind of metallic compounds have a wide range of application possibilities. These materials have a homogeneous structure, low internal stresses and low cost, which make them able to create magnetostrictive elements. Therefore, GMM can be used to develop positioning as well as vibration actuators with quick resp...

Structural health monitoring (SHM) using self-sensing cement-based materials has been reported before, where nano-fillers have incorporated in cementitious matrices as functional sensing elements. A percolation threshold is always required order for conductive modified concrete to be useful SHM. Nonetheless, the best pressure/strain sensitivity results achieved any matrix are <0.01 MPa−1. In th...

Abstract A significant efforts have been done by scientists and researchers in the last few years to develop many non-destructive techniques for damage recognition in a beam like dynamic structures. In this paper, theoretical, numerical, fuzzy logic methods employed for diagnosis of damage in the form of cracks of the cantilever composite beam with an aim to detect, quantify, and determine its ...

The provision of services in ubiquitous computing environments, or smart spaces, presents a number of unique management challenges. One of these challenges is to assure that the quality of service perceived by smart space users can be managed to meet user and provider goals. Such assurance will be complicated by the fact that many smart space services are composed, possibly dynamically, of a nu...

the aim of the paper is to analyze electro-thermo nonlinear vibration of a double-piezoelectric composite microplate-system (dpcmps) based on nonlocal piezoelasticity theory. the two microplates are assumed to be connected by an enclosing elastic medium which is simulated by pasternak foundation. both of smart composite microplates are made of poly-vinylidene fluoride (pvdf) reinforced by zigza...

The use of shape memory polymer composites is growing rapidly in smart structure applications. In this work, an active asymmetric composite called "controlled behavior composite material (CBCM)" is used as shape memory polymer composite. The programming and the corresponding initial fixity of the composite structure is obtained during a bending test, by heating CBCM above thermal glass transiti...
