1. Updating the role of matrix metalloproteinases in mineralized tissue and related diseases
Abstract Bone development and healing processes involve a complex cascade of biological events requiring well-orchestrated synergism with bone cells, growth factors, and other trophic signaling molecules and cellular structures. Beyond health processes, MMPs play several key roles in the installation of heart and blood vessel related diseases and cancer, ran

2. Modular modeling approach for FDM printed structures and piezo disks for metamaterial design
Abstract Research in metamaterials has recently gained interest in the field of noise and vibration control. The ability of creating band gap zones with minimum added mass is the main feature behind its success. In addition, the use of 3D printed parts, particularly the Fused Deposition Modeling (FDM), offers a practical solution for manufacturing parts with

3. Insights on Structuration of Peroxotungstic Acid in Aqueous Media
Recent studies on tungsten oxide preparation are mainly motivated by its applications in smart windows, energy harvesting and, recently, in cancer therapy. Peroxotungstic acid (PTA) is an important precursor to obtain tungsten oxide in an environmentally-friendly way, through the colloidal synthesis in aqueous media. Despite giving chemically pure products,

4. CYBER SECURITY GOVERNANCE AND MANAGEMENT FOR SMART GRIDS IN BRAZILIAN ENERGY UTILITIES
ABSTRACT The event of cyber security in critical infrastructures has aroused the interest and the worry of energy utilities, government, regulatory agencies, and consumers as well as of the academic and research institutions. If on one hand it is prominent the vulnerability of the cyberspace, which augments the risk of attacks in the organizational environme

5. Robust Optimal Control Applied to a Composite Laminated Beam
ABSTRACT: This paper proposes an active vibration control technique, which is based on linear matrix inequalities, that is applied to a piezoelectric actuator bonded to a composite structure, forming a so-called smart composite structure. Serendipity-type finite element, based on first-order shear deformation theory with rectangular shape, eight nodes, five

6. Vertical force calibration of smart force platform using artificial neural networks
INTRODUCTION: The human body may interact with the structures and these interactions are developed through the application of contact forces, for instance due to walking movement. A structure may undergo changes in the dynamic behaviour when subjected to loads and human bodies. The aim of this paper is to propose a methodology using Artificial Neural Network

7. A Numerical Study on Smart Material Selection for Flapped and Twisted Morphing Wing Configurations
ABSTRACT: The developments of innovative adaptive structures on Unmanned Aerial Vehicles (UAVs), such as morphing wings, can potentially reduce system complexities by eliminating control surfaces and their auxiliary equipment. This technology has the potential of allowing a UAV to adapt to different mission requirements or to execute a particular mission mor

8. A technique to package Fiber Bragg Grating Sensors for Strain and Temperature Measurements
This paper reports an effective method of packaging a fiber Bragg grating (FBG) for the simultaneous measurement of temperature and strain. The technique consists of embedding two fiber Bragg grating sensors inside a polymeric material with different geometrical characteristics. The mechanical and thermal characterizations of the optical transducer were perf

9. Micromechanical modeling and effective properties of the smart grid-reinforced composites
Smart composite structures reinforced with a periodic grid of generally orthotropic cylindrical reinforcements that also exhibit piezoelectric behavior are analyzed using the asymptotic homogenization method. The analytical expressions for the effective elastic and piezoelectric coefficients are derived. In particular, the smart orthotropic composite structu

10. The use of smart structures in the realization of effective semi-active Control systems for vibration reduction
The realization of semi-active actuators by smart structures is discussed. Semi-active actuators have the advantage of consuming much less power than direct-active actuators and are appropriate for the utilization in vibration problems encountered in aeronautical applications, where the loads are in general too high for direct-active actuators to perform.

12. Estudio de usabilidad de visualización molecular educativa en un teléfono inteligente
Chemistry students have difficulty understanding molecular structures and their functions. To aide their comprehension, molecular visualization software has been developed to run on smart phones, but in order to positively influence learning it must have a high degree of usability (usability measures how software is used in terms of efficiency, efficacy and
