- Volatile organic compounds (VOCs) represent a very important class of pollutants that causes serious health effects. There is an urgent requirement to establish efficient technologies that can reduce and control VOCs. Non-thermal plasma (NTP) is an emerging technology that can decompose low concentration VOCs. However, the low efficiency and high power cost are major hindrances in its commercialization. In this work, Co-Cu with TiO2 support catalysts are prepared by using the deposition precipitation method and utilized in post-plasma catalysis for the efficient degradation of toluene selected as a model VOC. The synergistic effect of Co-Cu/TiO(2)with different Co/Cu molar ratios along with pure Co/TiO2 and Cu/TiO2 catalysts are studied for their catalytic activity. Results showed that the degradation efficiency of toluene for the control experiments (plasma-alone) increased from 10 to 85% with the increase in input power from 11 to 44 W. In comparison, a significant improvement in the degradation efficiency is achieved with post-plasma catalysis owing to better physicochemical properties such as particle surface area and microstructures of the Co-Cu/TiO(2)catalysts. The Co-50-Cu-50/TiO2 exhibited highest degradation efficiency of toluene, i.e. 55% being 5.5 times higher than control at lowest input power of 11 W while 96% at the highest input power of 44 W, attributed to interaction of Co and Cu species, adsorbed oxygen content, and redox properties by exchange of pairs Co+3/Co+2 and Cu+2/Co+3. In summary, the post-plasma catalysis integrated with Co-50-Cu-50/TiO2 catalyst rendered optimal outcomes in terms of power consumption and degradation of VOCs, envisioning commercial viability.

A tool for automatic enterprise architecture modeling
- 2011
-
In: Proceedings of the CAiSE Forum 2011. ; , s. 25-32
-
Conference paper (peer-reviewed)abstract
- Enterprise architecture is an approach which aim to provide decision support based on organization-wide models. The creation of these models is however cumbersome as multiple aspects of an organization need to be considered. The Enterprise Architecture approach would be significantly less demanding if data used to create the models could be collected automatically. This paper illustrates how a vulnerability scanner can be utilized for data collection in order to automatically create enterprise architecture models. We show how this approach can be realized by extending an earlier presented Enterprise Architecture tool. An example is provided through a case study applying the tool on a real network.

The Enterprise Architecture approach would be significantly less demanding if data used to create the models could be collected automatically. This paper illustrates how a vulnerability scanner can be utilized for data collection in order to automatically create Enterprise Architecture models, especially covering infrastructure aspects. We show how this approach can be realized by extending an earlier presented Enterprise Architecture tool. An example is provided through a case study applying the tool on a real network.

The Enterprise Architecture Analysis Tool–Support for the Predictive, Probabilistic Architecture Modeling Framework

Conference paper (peer-reviewed)abstract
- The business of contemporary organizations is heavily dependent on information systems. Business processes and IT are interwoven and numerous technologies are in use. How the involved systems affect each other or impact the organizations' business domain is often uncertain, thus decision-making regarding information technology is challenging. Enterprise architecture (EA) is a holistic, model-based management approach. Many of the available EA software tools focus on documenting and have limited analysis capabilities. In this article, a tool for EA analysis is presented, supporting the analysis of properties such as business fit, security, and interoperability. The tool is implemented to support the Predictive, Probabilistic Architecture Modeling Framework to specify and apply assessment frameworks for performing property analysis on EA models.
