This paper describes the methodology used to transform the 2001 Swiss SAM devised at ETH Zürich and align it to the requirements of the GEMINI-E3 model which is based on the GTAP database. ...
Understanding stakeholders’ needs is necessary to design requirements for organizations and IT systems. We present a systemic modeling method to identify and categorize stakeholders within value networks, to analyze the relationships between these value ne ...
Intelligent Transportation Systems (ITS) can only operate successfully if selection and training of personnel is carried out in a systematic, theoretically sound way. Given the increasing responsibility of operators working in the control room, a scientifi ...
The effect of substrate permittivity on UWB antenna radiation is studied. Microstrip and CPW-fed UWB monopoles are designed using substrates with different dielectric constants. The radiation patterns are measured. The transfer function of a two identical ...

We experimentally investigate the out-of-plane radiation losses of photonic crystal coupled-cavity waveguides. We observe a strong variation in the losses along the dispersion curve and show that such variation is closely linked with the specific far-field ...
This paper is intended for teachers and students dealing with antenna engineering. Graphical tools have historically been used for illustrating many basic features of radiation patterns, such as the position and number of secondary lobes, null angles, and ...

Spatial filtering is the fundamental characteristic of microphone array based signal acquisition which plays an important role in applications such as speech enhancement and distant speech recognition. In the array processing literature, this property is f ...
An antenna exhibiting a very wide bandwidth with reconfigurable rejection within the band is presented. The proposed topology is versatile in terms of the number of available antenna states and location of the rejection frequencies, and also allows the ope ...

Motivated by the fabrication potential of multi-walled carbon nanotube structures, we numerically investigated a paired structure consisting of two metallic spheres each grown on one end of a multi-walled nanotube. The paired two-segmented structure is cap ...
This paper presents the design and implementation of a circularly polarized stacked patch antenna element for Ka-band applications. The printed element has been developed to be used in a LEO satellite antenna array. Two circular stacked patches, with air g ...
