Abstract: Modern identification technologies such as radio-frequency identification, or RFID, have become increasingly important for streamlining production and logistics operations in almost every industry. In steel industrial enterprise, there is many logistic information which is still collected manually. It brings out many disadvantages such as inaccurate logistics information, irregular logistics, be lasted feedback and so on. In this paper, presents the feasibility of deploying RFID for the steel industry as a tool to reduce the production costs. Steel industry that is applicable to RFID-based tracking management system is proposed. And basically small and medium-sized steel industries, reflecting the characteristics of the building systems and by allowing for faster application time, while minimizing the capital investment.
Abstract: The work aims to describe the issue of the approach related to structural problems, both for valuable and minor manufacts existing in the Italian historical town centers. The heterogeneity shown by these constructive typologies should coincide with some heterogeneity of the structural approach, but this is not always feasible, so computational processes and a strict application of the norms are often used in automatically. A representative case, as an example of the above-mentioned kinds of buildings (which are valuable, but not so much as to require a tailored intervention that takes into account the whole constructive history and the changes over the time), is shown. Ricciardelli palace (or Palazzo Ricciardelli) presents a great difficulty as to the structural intervention, but the approach used was a "classical engineer approach", formulated on the basis of the new computing tools and the new constructive norms. The restoration and the consolidation of this artifact have been well conducted by technicians, but the result is an invasive intervention that doesn't respect the original structural configuration of the construction. So the paper explains and discusses some investigation methodologies, alternative to an elastic analysis, which could be used in these cases, with the awareness that they are not completely exhaustive and far far away from the determination of a general formulation for a “unique model”, which can be representative of the masonry material, as well as from a definition that catalogues all its several features.
Abstract: In this study, a new inverse analysis framework for estimation of myocardium constitutive parameters is established. In this framework, by using cardiac magnetic resonance image of realistic human left ventricular, a more realistic, finite element analysis model for analyzing the deformation of left ventricle during diastole is introduced. The anisotropic nonlinear Holzapfel-Ogden constitutive model is used to describe the material behavior of myocardium. Estimating the parameters as for the inverse problem of left ventricle deformation, a novel hybrid simplex and particle swarm optimization algorithm is proposed to estimate the parameters of myocardium’s constitutive model. Numerical examples presents that finite element analysis results and the estimated parameters are in good agreement with the experimental data reported in literature, comparing with current optimization algorithm, the presented hybrid optimal algorithm can estimate the constitutive parameters more efficient. The efficiency and validity of the proposed parameter estimation framework is demonstrated.

Abstract: This paper presents the use of Three-Dimensional Finite Element Method (3D-FEM) for biomechanical analysis on dental implant prosthetics. This research focuses on three patents of threads of dental implant systems from United States Patent and Trademark Office (USPTO) and two new conceptual design models. The three-dimensional finite element analysis is performed on dental implant models, with compressive forces of 50, 100, and 150 N, and a shear force of 20 N with the force angle of 60 degrees with the normal line respectively. The Stress and displacement analysis is conducted at four different areas (abutment, implant, cortical bone, and cancellous bone). Findings from this research provide guidelines for new product design of dental implant prosthetics with stress distribution and displacement characteristics.
Abstract: Controlling chaotic dual-ring erbium-doped fiber laser and the produced dynamics are studied by modulating or shifting the laser loss while the control model is presented to pressure behavior of the laser to a periodic state or multi-periodic states by a periodic signal perturbing or shifting the loss. When the loss of one ring of the laser is modulated via a sinusoidal signal, chaotic behaviors of the dual-ring can be pressured in two single-periodic states while two rings emit cyclic pulses. It indicates that chaotic dual-ring erbium-doped fiber laser is effectively controlled. When another sinusoidal signal is taken to perform on the loss, the laser can be educe to present a period-2 or period-3 state. When the loss is shifted between two different levels, the dual-ring can be deduced to a period-4, a period-6 and other multi-periodic state. The results indicate that controlling chaotic dual-ring erbium-doped fiber laser can be realized via the chaos-control method.
Abstract: In this work, we proposed and demonstrated an efficient optoelectronic system capable to detect 1 gram of salt per liter of water (0.1% salinity) in real time employing optical fiber technology as sensing medium and embedded systems of National Instruments Company to get an accurate instrumentation process. In addition, the sensitivity of this salinity sensor can be enhanced by reducing the diameter of the optical fiber sensor structure ( by employing a controlled tapering process. More specifically, the sensitivity of this device has been raised from 141.933 nm/Refractive Index Unit (RIU) for an un-tapered sensor structure to 352.915 nm/RIU for a tapered sensor structure . In fact, considering that the tapered sensor structure provides an approximately linear response with a maximum sensitivity of 0.6624 nm / % salt, the percentage of salt is easily identified by monitoring the peak wavelength response.
Abstract: Regardless of fire heat or short circuit high temperature melting, the residual traces which represent the environmental characteristics can be found in copper and aluminum wires. The primary short circuited melted mark identification must be scientific and objective for physical evidence of the electricity fire during detecting, and the conclusions are related to the fire survey process. Currently, identification method of electricity fire, including macroscopic method and metallographic method, is very general and lacking of standard reference map and detailed description. According to the macro and micro characteristics and formation mechanism of various fire wire melted marks and the characteristics of metallographic organization of primary short circuited melted mark, two actual cases were analyzed in detail so as to distinguish the relationship between the melting reason and fire cause and to confirm that these two fires are caused by primary short circuit.
