Published: January 2014

Monitoring and tracking dangerous goods can represent a great improvement in security and safety when transporting hazardous goods by water road. In this paper we propose a complete monitoring and tracking system, which is able to check at the same time the position and real-time status of dangerous goods of the ship, as well as the conditions in the cargo bay. The system exploits battery-powered environmental sensors (temperature, humidity, pressure, gas concentration and liquid level), connected by a ZigBee-based Wireless Sensor Network, This approach guarantees flexibility, ease of deployment and low power consumption. Collected data is then sent from the ship to a fixed server via a GPRS link. The GPS positioning system is integrated by the use of Navigation System, which also guarantees a precise estimate of the position when the GPS signal is weak or temporarily lost. When dangerous goods of the ship start leaking, the system can develop a plan to solve the accident, according to the situation at that time.

Published: January 2014

The cloud computing offers dynamically scalable online resources provisioned as a service over the Internet cheaply. However, the security challenges it poses are equally striking. The reliable user authentication techniques are required to combat the rising security threat in cloud communications. Due to the non-denial requirements of remote user authentication scheme, it is most commonly achieved using some form of biometrics-based method. Fingerprint authentication is one of the popular and effective approaches to allow the only authorized users to access the cryptographic keys. While the critical issue in remote biometric cryptosystem is to protect the template of a user stored in a database. The biometric template is not secure and the stolen templates cannot be revoked, which is easy to leak user identity information. To overcome these shortcomings, in this paper, an indirect fingerprint authentication scheme is proposed. Further, we apply this secure scheme to the cloud system combing with PKI mechanism. At last, a comprehensive and detailed security analysis of the proposed scheme in cloud computing is provided.

Published: January 2014

As the world of semiconductor is moving towards smaller and high-end applications, the quality of the bonding adhesion for wire bonding is very critical. Although aluminium has been the metallization of choice in integrated circuits, it can be easily oxidized during high temperature and pressure. On the other hand, Platinum metallization layer has high thermal coefficient resistance and inert to oxygen. This paper reports the correlation between surface roughness and the wettability in the form of contact angle for Platinum deposited wafer etched using Inductively Couple Plasma-Reactive Ion Etching (ICP-RIE). Surface roughness was measured using AFM while contact angle was obtained via droplet test. The results clearly suggested that both surface roughness and wettabily, calculated by its contact angle value has the same trend. Surface roughness is directly proportional to the contact angle. This indicates that surface roughness have great influence on the surface wettability. Therefore, the adhesion for wire bonding process on platinum metallization which can be used in high end applications can be controlled by its surface roughness and wettability.

When two slender pipes were girthed weld, some of un-solidified solder liquid would ooze from the weld gap. Then the weld beading would be formed in the pipeline after solidification. It is difficult to be cleared away because of the higher hardness. Up to now, there was no effective method to solve this problem. So how to guarantee the pipeline quality was a big question, and it would influence the benefit of companies seriously. This paper presents a new cleaner to solve this problem. The cleaner was driven by direct current motor, and the cutting tool mechanism was driven by pneumatic motor which can carry different kinds of cutting tools. For the question of passing through the bend, the cleaner was designed to specified size after accurate analyzing. And another significant part was monitor, which was mainly composed of camera and video. In the end, we designed a model cleaner and manufactured it. The cleaner had been tested on spot and achieved the desired effect.

Pressure Difference for Moving Nitrogen Bubbles in a Waving Duct
Authors: Wang Zhan Xu
Published: January 2014

A duct with varying cross-sections can show some essential features of the motion of foam in porous media. In this paper, the effective viscosity of the bubbles train moving through cylindrical ducts with sinusoidal cross-section was experimentally measured. The test tube has total length of 1.14 m and has constrictions at interval of 0.0095 m. It is found that the foam effective viscosity is much higher than water viscosity and it is possible to extend the foam rheology correlations in constant cross section ducts to predict the flow differences in waving ducts.

Published: January 2014

Finite element analysis has been done to analyze pump bearing assembly in interference assembly condition by ANSYS software. The press-in assembly environment has been simulated, and the maximum stress and maximum deformation of inner race have been analyzed. Studies show that with the increase of bearing size, the change law of maximum stress and maximum deformation does not single unidirectionally increase or decrease simply. At the same time, the interference value also influences the change law. So, in the bearing assembly tolerance selection the influence of the interference must be considered fully. The finite element analysis can guide the selection of fit tolerance.
