    Opis:
    The aim of this paper is to describe a split S-shaped composite meta atom which shows double negative characteristics at resonance frequency. The proposed meta-atom structure exhibits an almost 3.70 GHz bandwidth when the operating frequency from 8 to 14 GHz (X-band). In this study, the ring width, split width, size of substrate material, and the substrate material itself are varying to investigate their effect on the resonance frequencies. Metal strips of the outer resonator are the splits and the inner ring resonator is designed in a way that it forms a split S-shaped structure on the epoxy resin fibre (FR-4) substrate material. The CST Microwave Studio electromagnetic simulator software was used for the design and simulation purposes, and an Agilent N5227A vector network analyser was used for practical measurements.

    Opis:
    In this paper, an effective medium ratio obeying, negative refractive index, compact meta-atom was designed, manufactured and tested for operation in a multiband microwave regime. The proposed meta-atom structure obeyed better effective medium ratio. The results of the measurement were verified by the commercially available Computer Simulation Technology (CST) Studio Suite 2014 simulator. The effective medium ratio obeying meta-atom displayed multiband response, in conjunction with negative refractive index property over a certain frequency band in the microwave frequency span. Furthermore, a few parametric analyses were completed with the meta-atom, and the effective medium parameters were investigated. The sizes and complex scattering constitutive parameters of the proposed negative refractive index, compact meta-atom are applicable for multiband applications in microwave regime.

    Opis:
    Model-driven engineering (MDE) provides the available tools, concepts, and languages for creating and transforming models. One of the most important successes of MDE is model transformation; it permits the transformion of models that are used by one community to equivalent models that can be used by another one. Moreover, each community of developers has its own tools for verification, testing, and test-case generation. Hence, a developer of one community who moves to another community needs a transformation process from the second community to his/her own community and vice versa. Therefore, the target community can benefit from the expertise of the source one, and the developers do not begin from zero. In this context, we propose an automatic transformation in this paper for creating a bridge between the BPMN and UML communities. We propose an approach and a visual tool for the automatic transformation of BPMN models to UML activity diagrams (UML-AD). The proposed approach is based on meta-modeling and graph transformation and uses the AToM3 tool. Indeed, we were inspired by the OMG meta-models of BPMN and UML-AD and implemented versions of both meta-models using AToM3 . This latter one allows for the automatic generation of a visual-modeling tool for each proposed meta-model. Based on these two meta-models, we propose a graph grammar that is composed of 58 rules that perform the transformation process. The proposed approach is illustrated through three case studies.
