The rate at which research ideas can be prototyped is significantly increased when re-useable software components are employed. A mission of the Computational Infrastructure for Operations Research (COIN-OR) initiative is to promote the development and use of reuseable open-source tools for operations research professionals. In this paper, we introduce the COIN-OR initiative and survey recent p...

This paper introduces a multiple rule engine agent architecture intended for prototyping heterogeneous agents. It also briefly describes how this same architecture might be used for concurrent and hierarchical goal processing. The proposed framework has an embedded main rule engine supporting goal processing as well as providing high level decision and control for the agent. It also possesses a...

in this research different types of al2o3 were used as supports to prepare catalysts for dehydrogenation of isobutane to isobutene. these supports were al2o3 from merck, axen and gamma al2o3 synthesized from al(oh)3. sn/pt/al2o3 catalysts were prepared by sequential impregnation, at first pt and then sn was deposited. characterization of catalysts was performed by x-ray powder diffraction (xrd)...

Using a middleware when designing a new distributed application allows portability across numerous software and hardware architectures, but introduces a new layer of potential incompatibilities due to the existence of various middleware standards. This paper presents the architecture of DROOPI (Distributed Reusable Object-Oriented Polymorphic Infrastructure). This project aims at defining and i...

In this work, biochar produced from Indonesian rice husks. Then used as adsorbent of Cr(VI) in aqueous solution. The XRD pattern showed the characterization at 23º (002) reflection, appearance silicate oxide, and carbon vibrations. surface area SEM morphologies confirmed that after pyrolysis treatment husk has changed. increased thermal treatment. adsorption study by demonstrate 2nd-order react...

Recent achievements in next-generation sequencing (NGS) technologies lead to a high demand for reuseable software components to easily compile customized analysis workflows for big genomics data. We present ViennaNGS, an integrated collection of Perl modules focused on building efficient pipelines for NGS data processing. It comes with functionality for extracting and converting features from c...

in this research na-y was synthesized by hydrothermal method and used as support for preparation of sn/pt/na-y catalysts using two different tin precursors, bu3sn(cl) and sncl2.2h2o, by sequential impregnation, in which the pt  was deposited first and in the next step sn was deposited. the catalysts were characterized by h2 chemisorption, transmission electron microscopy (tem), scanning electro...

catalysts with the formula of laco(1+x)o(3+δ), where 0 ≤ x ≤ 1, were studied for oxidation of co and c2h6 in a synthetic exhaust gas, comprising 6.0 % co and 0.2 % c2h6 in ar. ethane was selected as a model for hydrocarbons in the exhaust gas. the performance of catalysts is correlated to their properties, particularly their redox in oxidizing and reducing atmospheres. xrd patterns show perovsk...

the stereospecific polymerization of conjugated dienes began in 1954 with the first catalysts obtained by combining ticl4 or ticl3 with aluminum-alkyls, i.e. the catalytic systems previously employed for ethylene and propylene polymerizations. subsequently, many other catalytic systems were obtained and examined by a combination of transition metal or lanthanide compounds with appropriate alkyl...
