Optimization Of Real-Time Protocols For Wireless Packet-Switched Multimedia Networks Based On Partially Observed Multivariate Point Processes, William S. Hortos Aug 2001

Optimization Of Real-Time Protocols For Wireless Packet-Switched Multimedia Networks Based On Partially Observed Multivariate Point Processes, William S. Hortos

Electrical Engineering and Computer Science Faculty Publications

Next-generation wireless networks have been designed to transport integrated multimedia services based on a cellular extension of a packet-switched architecture using variants of the Internet protocol (IP). Each call, arriving to or active within the network, carries demand for one or more services in parallel, where each service type has a guaranteed quality of service (QoS). Admission of new calls to the wireless IP network (WIN) from the gateway of a wired network or from a mobile subscriber (MS) is allowed by call admission control (CAC) procedures. MS roaming among the nodes of the WIN is controlled by handoff procedures …

Uneven Anodic Dissolution Of Iron Induced By Magnetic Field, Zhan-Peng Lv, De-Lun Huang, Wu Yang Aug 2001

Uneven Anodic Dissolution Of Iron Induced By Magnetic Field, Zhan-Peng Lv, De-Lun Huang, Wu Yang

Journal of Electrochemistry

The effects of magnetic field on anodic dissolution of iron in sulfuric acid were studied by potentiostatic polarization measurements and scanning electron microscopy observation. Magnetic field would reduce the surface film coverage fraction on electrode by enhancing the film dissolution process, thus made the electrode prone to active dissolution state. With increasing the applied potentials, magnetic field would accelerate the anodic dissolution, change the oscillation state or passive state to active dissolution state, or maintain the passive state, respectively. Potential for onset of passivation moved in the noble direction when magnetic field was imposed. At specific anodic potentials, denting occurred …

Simultaneous Determination Of Gold(Ⅲ) And Copper(Ⅱ) With Two-Way Stripping Voltammetry, Rong-Zong Hu, Dong-Ping Wei, Guang Wei, Yue-Ying Liu Aug 2001

Simultaneous Determination Of Gold(Ⅲ) And Copper(Ⅱ) With Two-Way Stripping Voltammetry, Rong-Zong Hu, Dong-Ping Wei, Guang Wei, Yue-Ying Liu

Journal of Electrochemistry

A novel Two-way Stripping Voltammetry method for simultaneous determination of Au3+ and Cu2+ was reported in this paper. Because of the strongly electrostatic attraction of carbon paste electrode towards Au(Ⅲ) ion at positive potential and the biochemical contribution of Gram-positive bacteria strain DO1, the ion can be determined by cathodic stripping voltammetry. At the same time, Cu(Ⅱ) is reduced readily under the catalysis of ultra-fine gold particles, thereafter it can be determined by anode stripping voltammetry. There is no interference between the determination of Au3+ and Cu2+ . A perfect liner relationship between the concentrations of …

The Activation Mechanism Of Al Alloys With Tin And Gallium In Alkaline Electrolytes, Zhen-Ya Li, Ling Yi, Zhi-Hui Liu, Lin Yang, Jing-Xin Su, Yan-Ying Chen Aug 2001

The Activation Mechanism Of Al Alloys With Tin And Gallium In Alkaline Electrolytes, Zhen-Ya Li, Ling Yi, Zhi-Hui Liu, Lin Yang, Jing-Xin Su, Yan-Ying Chen

Journal of Electrochemistry

The major reason for Al-anode's activation is that Ga and Sn deposit on the aluminum surface and form activated points. The Al-Sn and Al-Ga binary alloys can't be activated in alkaline medium. During the dissolution of the Al-Sn-Ga ternary anode, Sn and Ga dissolve into the solution and transform into ions. After the Sn ions deposit on the surface of Al-anode, the Ga ions will deposit on Sn. The higher activation of the polynary alloy anode is caused by much more new activated points composed of Ga-Sn alloy being continually formed. Ga- Sn alloy with low melting point deposited on …

A New Method For Impregnating Nafion Solution Into The Electrode Of Pemfc, Qian Tang, Ming Han, Bao-Lian Yi, Zhi-Yin Lin Aug 2001

A New Method For Impregnating Nafion Solution Into The Electrode Of Pemfc, Qian Tang, Ming Han, Bao-Lian Yi, Zhi-Yin Lin

Journal of Electrochemistry

We have developed a new method for impregnating Nafion solution into the catalyst layer of homemade hydrophobic electrode using capillary process. Those electrodes show better performance and higher utilization of catalyst (detected by CV and TEM) than traditional spray method in PEMFC. According to the results of SEM photograph and linear-analysis of sulfur and platinum for the electrode cross-section, we can conclude that the resin is uniform in the catalyst layer and has almost same depth as catalyst in the impregnated electrode. While in traditional method resin is not uniform in the catalyst layer and penetrates into the diffusion layer, …

Simultaneous Projectile And Target Ionization In He⁺ + Ne Collisions, J. Fiol, Ronald E. Olson, A. C.F. Santos, G. M. Sigaud, E. C. Montenegro

Physics Faculty Research & Creative Works

Cross sections for single and multiple ionization of the target atom with simultaneous ionization of the projectile have been measured for 1-4 MeV collisions of He+ with Ne. The observations are interpreted using the n-body classical trajectory Monte Carlo method. The 11-body calculations include the L-shell electrons of the Ne and the K-shell electron on the He+. In this model, each electron interacts with both nuclei and with all the electrons belonging to the other centre. For single ionization from both centres, it is found that the dynamical electron-electron (e-e) interaction produces a clear signature in the …

The Coulostatic Method For Evaluating Corrosion In Reinforced Concrete, Yong-Tao Zhao, Jian-Hua Wu, Chang-Jiu Zhao Aug 2001

The Coulostatic Method For Evaluating Corrosion In Reinforced Concrete, Yong-Tao Zhao, Jian-Hua Wu, Chang-Jiu Zhao

Journal of Electrochemistry

In the present paper, the application of the coulostatic method to the corrosion of steel in concrete was reviewed. By comparing with other electrochemical techniques, the results obtained in the previous work reveal that the coulostatic method is an interesting alternative to the usual procedures for estimation of corrosion rate, and is better than them in some respects. The main advantages are as follows. The signal to be used can be instantaneous and as small as desired, so the electrode is minimally perturted during the measuring process. In addition, it is as rapid and quantitative, and at least as reliable …

Characterization And Electrochemical Investigation Of Boron-Doped Mesocarbon Microbeads Anode Materials For Lithium-Ion Battery, Mao-Hui Chen, Guo-Tao Wu, Guang-Ming Zhu, Jin-Kua You, Zu-Geng Lin

Journal of Electrochemistry

The anodic performances of boron doped and undoped mesocarbon microbeads(MCMBs) were comparatively studied and the structures were characterized by XPS, SEM, XRD and electrochemical measurements. It was found that boron doping samples greatly increased the degree of graphitization and the crystallite size, leading to quite different morphology. Electrochemical discharge/charge cycle tests indicate that lithium intercalation occurred at a little higher potential for the boron doped MCMBs, being attended by greater irreversible capacity loss.

The Dissolution Of Perfluorinated Proton Exchange Membrane And The Analysis On The Performance Of The Recast Membrane, Hong-Feng Xu, Xi-Qiang Yan, Xuan Li, Li Wan

Journal of Electrochemistry

Perfluorinated resin solution is useful in proton exchange membrane fuel cell. At 270～280 ℃ and protected with N2, the proton exchange membrane(Nafion 115) was dissolved in the dimethyl sulfoxide, and two kinds of membrane solutions were obtained. With those solutions, a recast membrane was prepared. The exchange capacity, rate of water content and conductivity of the recast membrane were measured. The results show that the properties of the recast membrane are lower than those of its mother membrane. This may be caused by that some sulfonic acid groups were destroyed in the dissolving process.
