Present study showed synthesis of novel type porous alkali niobate piezoelectric ceramics, and the formation domains photocatalytic activity for ceramics were investigated while comparing with dense to confirm enhancement domain orientation around pores. Porous Li0.06Na0.47K0.47NbO3 synthesized by a template method using polymethylmethacrylate as pore former agent. Uniform pores 6 µm in diamete...

Abstract. The increasing interest in software agents and multi-agent systems has recently led to the development of new methodologies based on agent concepts. The Tropos framework offers an approach to guide the development of agent-oriented systems by using concepts based on requirements engineering. In this paper, we concentrate on the detailed design and implementation phases of the Tropos a...

A novel protocol is proposed to address the problem of user authentication to smartcards using biometric authentication instead of the usual PIN. The protocol emulates expensive Match On Card (MOC) smartcards, which can compute a biometric match onboard, by using cheap Template on Card (TOC) smartcards, which only store a biometric template. The biometric match is performed by a module running ...

Three-dimensional cubic ordered mesoporous carbons with tunable pore sizes have been synthesized by using cubic Ia3d mesoporous KIT-6 silica as the hard template and boric acid as the pore expanding agent. The prepared ordered mesoporous carbons were characterized by powder X-ray diffraction, scanning electron microscopy, transmission electron microscopy, and nitrogen adsorption-desorption anal...

This paper proposed a WebGIS-based, template oriented and on-line group spatial decision support system for Investment Environment analysis. This system provides online mapping, online spatial and non-spatial information query and online multi-criteria evaluation through Internet by integration of WebGIS and analytical module. Template servers as the “smart agent” between user and system, it pr...

The creation of new ad-hoc methodologies through the Situational Method Engineering approach needs the process fragments to be defined and available. Thus, it is necessary to previously define and extract such fragments from the global development process. So, it is important to provide the means of documenting the whole process from which fragments will be obtained. This paper presents an expe...

Nitrogen and metal doped nanocarbons derived from polyaniline (PANI) have been widely explored as electrocatalysts for the oxygen reduction reaction (ORR) in fuel cells. In this work, we report surfactant-template synthesis of PANI nanostructures and the ORR electrocatalysts derived from them. By using cationic surfactant such as the cetyl trimethyl ammonium bromide (CTAB) as the template and t...

Of the many ways to make synthetic hosts, one of the most appealing involves molecular imprinting. In the commonest approach monomer units assemble around or are attached to a template (imprint) molecule and then linked together using a cross-linking agent. Template removal ideally leaves cavities within the molecularly imprinted polymer (MIP) that possess a shape and functional group complemen...

Antibiotic U-20,661 was shown to inhibit predominantly deoxyribonucleic acid (DNA)-directed ribonucleic acid (RNA) synthesis by binding to the double-stranded DNA template. Specific binding to DNA was verified by difference spectroscopy, reversal of the RNA polymerase inhibitory effect by increasing concentrations of DNA template, and by moderately increasing the melting temperature of double-s...

Today's application engineers are committed to the reuse of programs for perjormance and economic reasons. Moreover, they increasingly have to complement application programs with less information and in shorter time. The reuse of already implementedprograms is therefore fundamental. We have implemented a process automation specific framework that supports reuse of our domain specific visual la...
