Among the various road repair technologies, overlay asphalt above crashed slab has been increasingly paid close attention by engineer. as the size of broken cement concrete slab is reduced in this repair methods, the shrinking displacement reduced greatly as temperature falls and Thus also reduces the overlay tensile stress, these reductions can effectively prevent and eliminate the reflection crack of overlay; Meanwhile, the deflection quantity and deflection sent of joints and fissures on both sides of the slab also reduced because of the lower plate size which can greatly improve pavement structure reliability and durability; However, the crushing also reduces the old cement concrete slab stiffness which make the characters of broken concrete layer between the flexible and semi-rigid, and so the graded properties and stability of the crashed layer is hard to control and its stress-strain characteristic is also different with general elastic layered pavement system[1-2].
Because of the above reasons, to correctly understand the material characteristics of crashed layer and its comprehensive mechanical response with overlay will conduct the designer to design reasonable overlay and builder to make scientific treatment.
Reliability analysis theory According to the definition of Unified standard of reliability design of highway engineering structures ,it takes the randomness and instability of influence factors such as traffic, material strength of structure layer, modulus, thickness, construction condition and climate into consideration which will affect the pavement structure design and evaluation and use the whole or part failure probability to measure the reliability of the asphalt pavement structure, that can reflects actual working condition of pavement structure more objectively[6].
This paper combined the existing traditional JC method with finite element program and take advantage of characteristic that modulus is expressed by explicit function in finite element program, and then embedded the basic formula of JC method into finite element constitutive equations in order to calculate the mechanical response index which can derive the gradient of pavement structure function and finally get reliability index in order.

By introducing the deviation factors such as seal strip reaction force and door’s dynamic deformation, the closed-loop relationship of size of the sliding-door system when it is in closed state is further established.
Multidisciplinary optimization (MDO) method was used in their study to establish the intersected feasible region for different constraints, and the sensitivity and the contribution of each respective feasible region have also been analyzed Fukumara et. al [2] used the finite element method to analyze and simulate the deformation defects of the car door panels, and obtained the explicit solution of the outer plate deformations simulation; Wagner [3] analyzed the three important performance factors in the study and design of the seal strip performance of car doors: mechanical and deformation characteristics, contact pressure distribution, and pressure difference; Zou et. al [4] developed an effective method for door system reliability analysis by using doors deviation characterization, and the higher efficiency and accuracy of this method were proved by numerical examples.
The dynamic performance of a sliding door system in closed state is affected by the characteristic of the seal strip itself and also the installation deviation.
With the aim to resolve this issue and find the factors that affect the overall dynamic performance of the sliding door in closed state, a flexible deviation model of the sliding doors is proposed in this paper on the basis of influence coefficient method, and the closed-loop size relationship of the door system in closed state is also established.

During mass production, one of the key factors in costs reduction is to enhance lifetime of the molding tools.
In this study, a novel material made of a nickel-phosphorus-polytetrafluoroethylene (Ni-P-PTFE) compound was plated electrolessly on experimental dies to study relevant properties.
Since Ni-P-PTFE exhibits strong anti-adhesion properties, it is noted to improve the lifetime of the dies.
In conclusion, the adhesion phenomenon is interpreted via hydrophobic contact angles showing that hydrophobic contact angle of Ni-P-PTFE surfaces is smaller when compared to Ni-P surfaces which infers the anti-adhesion properties of Ni-P-PTFE materials.
Finally, hydrophobic effects in term of contact angle measurement are used for demonstration of anti-adhesion properties of Ni-P-PTFE plated surface.

Location of the restoration, the type of support and the design of the restoration were assessed as possible factors influencing chipping rate.
Introduction During the recent years, zirconia-based restorations have gained great popularity. [1,2] These metal-free restorations are considered to offer esthetic biocompatibility, as they contain a zirconia framework that can come in multiple shades to provide a more biomimetic outcome.[3] They offer improved optical properties – the light transmission is better than that of metal-ceramic restorations, which are very opaque.
Several factors have been investigated in laboratory studies, among which: the thermal compatibility of the veneering ceramics and the zirconia frameworks [11], the surface treatment of the framework, the bond strength between the veneering ceramic and the zirconia framework and the flexural strength of the veneering ceramics [12].
Every complication affecting each unit of a restoration was documented as a separate incident.

Hypothermia and discomfort can be caused in cold climates due to perspiration and, along with rainfall, are factors that drastically reduce the insulation provided by the material used in the clothing [11].
However, the moisture transport properties can be more significant than the thermal insulation properties.
Thus, the thermal properties of fabrics are one of the most important characteristics of the textile materials [14].
If the ambient temperature is greater than the human body, the heat, through convective properties, is transferred to the soldier causing thermal stress, which can affect his health as well as his operational performance.

Introduction Orthotropic steel decks (OSDs) have been applied widely in modern large and medium span cable-braced bridges because of its prominent mechanical properties, and fast and convenient manufacturing.
According to statistical analysis of fatigue damage types, the trough splice joints as one of several kinds of major constructional details, which approximately accounted for 6.3 percent of total fracture cracks[3,4], was one of the key factors affecting the fatigue properties of OSDs.
The survey data showed that the unreasonable design of structure details and quality flaws of welded joints production were two major factors leading to the fatigue of OSDs.
