I. ABSTRACT Price differences exist in people’s daily life. The availability of real-time price information through mobile phone offers consumer benefits, which provide incentive for user contributions. For such schemes to be adopted, the cost of contribution must be more than offset by the benefit of the information. However, even in this high tech society, we have to accept the fact that such...

In this paper, we introduce a modified interpretation of the water activity presented in Springer et al. [T.E. Springer, T.A. Zawodzinski, S. ottesfeld, Polymer electrolyte fuel cell model, J. Electrochem. Soc. 138 (8) (1991) 2334–2342]. The modification directly affects the membrane ater transport between the anode and the cathode (two electrodes) of the polymer electrolyte membrane (PEM) fuel...

To study the formation of air pollutants and soot precursors (e.g., acetylene, 1,3-butadiene, benzene, and higher aromatics) from aliphatic and aromatic fractions of gasoline fuels, the Utah Surrogate Mechanisms is extended to include submechanisms of gasoline surrogate compounds using a set of mechanism generation techniques. The mechanism yields very good predictions of species concentrations...

To carry out the investigation, a cylinder pressure model was developed based on the position of the crankshaft, engine load, engine speed, and fuel injection time. This model takes into account the maximum number of parameters involved. The accuracy of the model was verified by experimental results. The average error of the cylinder pressure, the average radical of the square of the error of t...

This paper describes the approach towards signal processing characteristics for temperature fluctuations from a fast thermocouple located above fuel subassemblies of fast reactor. Simulated temperature profile denoting various power levels was fed to the FPGA and the RMS value at each power level was calculated in real time. The technique mentioned in the paper helps in the analysis of reactor ...

A proton conducting metallogel [FNPA; ferric nitrate (FN)-phytic acid (PA)] is synthesized by immobilizing a protogenic ligand (phytic acid) using iron(iii) nitrate in DMF. The xerogel shows high proton conductivity of 2.4 × 10-2 S cm-1 at 120 °C, the best value known among all metal organic materials (MOMs). Marking the first such attempt in MOMs, an electrode made using the xerogel showed a p...

One factor limiting solid oxide fuel cell (SOFC) performance is the degradation of chromium containing, ferritic stainless steel, interconnects during operation. When chromium-containing steels are used as interconnect materials a chromium oxide layer forms on the surface. Under SOFC operating conditions (Cathode gas 800oC and 2.5-3.1% H2O) chromium ions are vaporized by the cathode gas and red...

A simple and rapid spectrophotometric method has been developed for the determination of Pu in highly radioactive liquid waste. This method uses Nd(III) as an internal standard, which enables us to determine the concentration of Pu and to authenticate the whole analytical scheme as well. A Nd(III) standard mixed with a sample solution and Pu was quantitatively oxidized to Pu(VI) with Ce(IV) in ...
