Authors: Chuang Li Chin , Luo Chin Hsiang
Published: February 2011

Nanoindentation was used to measure the hardness and Young’s modulus of prepared-TiO2 films. The thickness and refractive index of the TiO2 films were measured using ellipsometry with a monochromator. Scanning electron microscopy was used to determine the micrography of the TiO2 films. Pure TiO2 films were prepared from sols made by 3 % (w/w) of prepared-TiO2 suspension solution coated onto silicon wafers. After the dip-coating was completed, the coatings were further treated by various procedures, natural air-drying, water-vapor exposure, and calcinations. The prepared-TiO2 films were smooth and free of macro cracking. The grain sizes of these films were uniform and in the range of 50–100 nm and the films were of rutile structure. The prepared-TiO2 coatings exhibited more favorable porosity in water-vapor exposure than those under other conditions. The T-H2SO4 coatings exhibited higher hardness and modulus than those with T-H2O and T-NH4OH coatings after high temperature calcination. The values of hardness and modulus for T-H2SO4 coatings were 11.93 GPa and 226.25 GPa, respectively. Curves of hardness and modulus as a function of depth (0–2200 nm) of the coatings under calcination conditions show a peak at shallow contact depth within 100 nm and then demonstrate being rather constant. The hardness and modulus curve obtained from T-H2SO4 coatings in water-vapor exposure are rather constant.

Published: February 2011

The TiO2 films were synthesized on Ti substrates by a novel method. Titanium metal was directly oxidized by hydrogen peroxide to generate a rough amorphous film and then hydrothermal process transformed the film to crystalline nanoflower TiO2 film. The obtained film can be modified by calcination with urea and the modified film can keep the nanoflower structure. According to the XPS data, the urea-induced modification is surface-modification rather than N-doping. Compared to the un-modified film, the response scope of the modified film extends to the visible light region. Photocatalytic activity of films were investigated by degrading methyl orange (MO) under visible light. As a result, 47% of MO was decomposed by modified film in 3 hours.

Authors: Zheng Shao Mei , Zhao Cheng
Published: February 2011

Plasma carburizing of AISI 316L austenitic stainless steel was carried out at low temperature to improve the surface hardness without degradation of its corrosion resistance. The microstructure, surface hardness, phase composition and corrosion property of the hardened layer were analyzed. The experimental results show that high-quality hardened layers can be produced at the carburizing temperatures between 673 K and 773 K, which have not only high surface hardness and wear resistance, but also good corrosion resistance. All of the hardened layers display a precipitation-free structure or Sc phase. The chromium carbides began to precipitate in the hardened layer as soon as the carburizing temperature is higher than 823 K. The precipitation of chromium carbides will lead to deterioration in corrosion resistance of the hardened stainless steel.

Published: February 2011

Research over the last decade has shown that composite floor structures can have a significantly greater fire resistance than is suggested by conventional tests on isolated elements, this is largely due to the interaction between the beams and floor slabs and beams-column connections in the fire compartment and the restraint afforded by the surrounding structure. This research was carried out to investigate the effect of fire on the behavior of reinforced concrete frames especially the connection between beam and column, where a special model for a fire furnace was designed in HBRC in order to investigate the aim of the current research. An experimental program consisted of thirteen statically independent two hinged reinforced concrete frames is designed to study the deformational behavior of RC frames subjected to fire under short term loading in terms of deflection and strain distribution, temperatures distribution along the critical cross sections at different limit states with the following variables: fire durations (1,2 and 3 hours), and fire temperatures (300,600 and 800°C) with concrete strength (250 and 600 kg/cm2). Modes of failure, ultimate capacity, deflection and strain of steel reinforcement and concrete at critical sections were examined experimentally and theoretically. The non-linear finite element analysis for reinforced concrete structure is largely dependant on the stress-strain relationships, failure criteria used, simulation of steel reinforcement and interaction between steel and concrete [1]. A model for predicting the behavior of reinforced concrete frames failure was developed based on experimental results obtained from the experimental program carried out by the authors. This model has been incorporated into a new reinforced concrete element for the non-linear analysis program, using ANSYS Ver.10 program. In this paper, a general description of the finite element method, theoretical modeling of concrete and reinforcement are presented. In order to verify the analytical model used in this research using test results of the experimental data of the experimental branch, the finite element analysis were performed then to be able to proposed a guide charts which can be used to predict the moment capacity of joint in beam-column connection in RC frames subjected to fire taking into consideration the different fire durations, fire temperature, and concrete strength.

Published: February 2011

Bioprocesses are appreciated as difficult to control because their dynamic behavior is highly nonlinear and time varying, in particular, when they are operating in fed batch mode. For this kind of bioprocess where the mathematical model contains many structured and unstructured uncertainties, we try to combine different intelligent techniques based on natural syllogisms of these techniques. In order to obtain a high bioprocess productivity it is essential to accord the benefits of the classical control strategy (i.e. the analytical determination of the optimum) with the subjective bioprocess characterization (due to the human expert) in order to diminish the on line information scarcity. The research objective of this study was to develop an appropriate control method for a new complex bioprocess and to implement it on a laboratory plant. Hence, an intelligent control structure has been designed in order to produce biomass and to maximize the specific growth rate.

Published: February 2011

This paper proposes and implements a comprehensive software system based on agents and mobile agents techniques, which firstly deals with the network admission control and authorization, adopting the traditional password authentication schema and an intelligent, flexible sensor whose kernel is the NDIS-hooking driver. Agent Message Protocol over UDP/TCP is proposed to secure and encrypt the communication data among stationary agents and server components, which eradicates malicious codes embedded or spread in the internal network. In order to avoid the above software agents mangled or destroyed, the proactive method of Grid Scanning model based on the Agent Message Protocol and Address Resolution Protocol can detect and spoof those clients whose agents are mangled; and if the users forge the logon info, this system can prevent the clients escaping from the control with the dual verification mechanism. Finally, the mobile agent infrastructure with flexible and effortless integration with this security system is introduced and implemented, which supports security access to resources on the controllable clients. Such solution in the internal network satisfies the security-related requirements of availability, expansibility, responsibility, and self-defense, as well as the non-security-related requirements of real-time, veracity, stability and flexibility.

The growing of P2P applications enriched the resources sharing by network, but it also brought many problems such as occupying network bandwidth, security of personal information. Therefore, the monitor of P2P applications is very important, and P2P protocol identification is the key point. So far since the P2P appeared, new P2P applications and data encryption made the traditional port-based and application layer protocol signature recognition useless. To overcome the shortcomings of current methods, a new P2P identification algorithm is proposed which uses DFI (Deep Flow Inspection) by extracting the various properties of P2P data stream characteristics, and then the data flows are divided into TCP and UDP data sets, finally the support vector machine optimized by particle swarm optimization is used to assort the network data streams, Experimental results of the P2P and non-P2P applications show that this algorithm can identify the HTTP applications 100% and for a variety of P2P applications, the accuracy of classification can also reach to 95%.

Reliability Assessment of Control Systems
Authors: Distefano Salvatore
Published: February 2011

Actually modern systems have to ensure higher and higher operating standards, thus including monitoring and control subsystems for their achievement. In safety critical systems control is a crucial task in order to satisfy strict reliability requirements. But it is also necessary that the control system is itself reliable. As a consequence, adequate techniques are necessary in order to perform reliability evaluation of both the controlled and the control systems. Techniques that therefore should avoid over-simplistic assumptions and/or approximations that, for example, are usually introduced when dependencies, interferences and other dynamic reliability aspects are not taken into the right consideration. In this paper, a technique for carefully evaluating the reliability of such systems, also considering dynamic aspects and behaviors, is proposed. Firstly the technique is detailed through the specification of the dynamic reliability block diagrams notation, and therefore in order to demonstrate its effectiveness, it is applied to an example of a computing-based control system taken from literature, thus providing guidelines for the reliability representation and evaluation through DRBD.
