Received: December 28, 2017 Revised: February 23, 2018 Accepted: February 26, 2018 Abstract: Background: For centuries, steel rebar has been the primary reinforcement in concrete despite its major drawbacks, such as its heavy weight, high electrical conductivity, and corrosiveness. Thus, in response to the need for better alternatives, innovative Hybrid Composite (HC) reinforcements have been d...

A Bayesian technique is presented to evaluate the coupling characteristics of complex vibro-acoustic or structural dynamic systems. Although there is no restriction on the applicability of the method in the whole frequency range, any such coupled system may be considered to be a hybrid system in the sense that its components may behave in their low-, midor high-frequency regimes. Inexact measur...

The goal of life-extending control is to achieve high performance of complex dynamical systems (e.g., aircraft, spacecraft, and energy-conversion systems) without overstraining the mechanical structures and the potential bene"t is an increase in the service life of critical components with no signi"cant loss of performance. This paper presents a two-tier architecture and a design methodology of...

A major challenge of designing a bioregenerative life support system for Mars is the reduction of the mass, volume, power, thermal and crew-time requirements. Structural mass of the greenhouse could be saved by operating the greenhouse at low atmospheric pressure. This paper investigates the feasibility of this concept. The method of equivalent system mass is used to compare greenhouses operate...

Face recognition presents a challenging problem in the field of image analysis and computer vision. The security of information is becoming very significant and difficult. Security cameras are presently common in airports, Offices, University, ATM, Bank and in any locations with a security system. Face recognition is a biometric system used to identify or verify a person from a digital image. F...

In this work, we describe the insertion of a water-soluble bisadduct fulleropyrrolidine derivative into the interlayer space of three layered smectite clays. The composites were characterized by a combination of powder X-ray diffraction, transmission electron microscopy, X-ray photoemission and FTIR spectroscopies, and laser flash photolysis measurements. The experiments, complemented by comput...

In this article, the state-of-the-art multi-wave and hybrid imaging techniques in the field of nondestructive evaluation and structural health monitoring were comprehensively reviewed. A new direction for assessment and health monitoring of various structures by capitalizing the advantages of those imaging methods was discussed. Although sharing similar system configurations, the imaging physic...

This paper contributes to the theory of hybrid substructural logics, i.e. weak logics given by a Gentzen-style proof theory in which there is only a limited possibility to use structural rules. Following the literature, we use an operator to mark formulas to which the extra structural rules may be applied. New in our approach is that we do not see this ∇ as a modality, but rather as the meet of...

introduction saline wastewaters contain mineral salts which are often produced by industries such as seafood processing, cannery, vegetables, and tanning. they are imported into the sewage collection network. in coastal cities, saline water consumption seems indifferent in household parts and highlevels ofground water, leaksaltwater, precipitation duringdifferentseasons,and sea level are the ot...

An ideal scaffold material is one that closely mimics the natural environment in the tissue-specific extracellular matrix (ECM). Therefore, we have applied hyaluronic acid (HA), which is a main component of the cartilage ECM, to chitosan as a fundamental material for cartilage regeneration. To mimic the structural environment of cartilage ECM, the fundamental structure of a scaffold should be a...
