At present, the wiring harness detection systems require a great number of testing cables, meanwhile, bring a series of problems, such as high cost, poor compatibility and low efficiency. In order to solve above drawbacks, we present a novel system based on the wireless network communication which is used for aircraft wiring harnesses' conduction test, and describe it from two aspects of hardware and software. The proposed system also can be extended to other industrial fields. © 2016 IEEE.

One effect from an underwater explosion on ship hulls is the direct pressure, and the other is to create acceleration. Furthermore, the acceleration is not only created by ship hulls, but also by additional mass, which is also known as additional water mass, namely the explosion changes momentum and kinetic energy of ship hulls and additional mass at the same time. The research on a structure under an underwater explosion is very complex and has a huge quantity of calculation. For the purpose of selecting a composite hull structure, explosion loading is equivalent to static loading by means of an energy principle, the momentum principle and d'Alembert principle. According to the response of five different hull structures to equivalent loading, we select a hull structure. To the same molded lines of five different hull structure forms as longitudinal framing, transverse framing, a combined system, a hard-shell form and a sandwich form, the same loading and equal weight as a condition, the ship's response created by an equivalent underwater explosion loading need to be analyzed by the finite element method. With the analysis of ship's stress and displacement, we compare the strength, rigidity, section modulus and comprehensive performance of a ship to provide a numerical analysis reference for a structure selection. One structure form should be selected not only conforms to a structural performance, but also satisfies the use requirement.

Optical loss of fiber-optic connectors has a vital impact on fiber-optic-related systems. We analyze the contact loss caused by the endface geometry and the contact force. Based on analytical and simulated results, the analytical equations of the insertion loss (IL) and return loss (RL) as a function of the endface geometry and the contact force are derived. Then four fiber-optic connectors are experimentally tested. The experimental results are well consistent with the theoretical results, which show that there is an optimum relationship between the endface geometry and the contact force to ensure a low IL and a high RL. © 2016 Society of Photo-Optical Instrumentation Engineers (SPIE).

A high performance Al-Al2O3 metal and oxide composite carbon-free sliding gate was prepared under carbon burial at 1450°C for 6 h via a transient plastic phase process using tabular alumina, fused white corundum, α-Al2O3 fine powder and a fine Al powder as raw materials and phenolic resin as binder. The composite samples with Al content of 9% in mass had the optimum comprehensive physical properties. The apparent porosity, bulk density, cold crushing strength and hot bending strength of the samples heated at 1400°C for 30 min were 4.1%, 3.27 g/cm3, 410 MPa and 60.7 MPa, respectively. The performance of the composite sliding gate prepared via the control of chemical reaction and calcining atmosphere was superior. Al reacted with both C and CO mixed with N2 could form Al4C3 and AlN, and Al4C3 continuously reacted with Al2O3 to form Al4O4C, Al2OC reinforcement phase and the remaining free Al as a metal plastic phase. The Al-Al2O3 composite sliding gate had a high chemical stability and a low oxygen potentiality, without any free C and hydrated Al4C3, which could be applied to clean steel production process, and the secondary C, O, H and other impurities from the sliding gate could not appear during the operation.

The natural frequency equations of fluid-structure interaction in pipeline conveying fluid with both ends supported is investigated by a direct method, and the direct method is derived from Ferrari's method which is used to solve quartic equations. The dynamic equation of pipeline conveying fluid with two variables is obtained by Hamilton's variation principle based on Euler-Bernoulli Beam theory. By using the separation of variables method and the derived method from Ferrari's method, the natural frequency equations and the critical flow velocity equations of pipeline conveying fluid with both ends supported are obtained in mathematical decoupling. Each order natural frequencies and critical flow velocities can be obtained by using numerical method. The first five order dimensionless critical flow velocities are obtained, and the results indicate that clamped-simply supported is less stable than clamped-clamped supported and more stable than simply-simply supported. All the conclusions can be applied to nuclear installations and other engineering fields of improving the vibration. © 2012 Elsevier B.V. All rights reserved.
