This paper presents a compact broadband stepped bow-tie antenna for ambient RF energy harvesting (RFEH). The proposed consists of shapes wide bandwidth, making it possible to investigate in entire cellular bands. In addition, the is composed shape achieve compactness internet things (IoT) sensors. We explain design steps taken this analyzing surface current distributions with respect number thr...

This paper proposes a quasi-isotropic hybrid dielectric resonator antenna (DRA) and bow-tie patch with harmonics suppression. The suggested consists of DRA, patch, microstrip seventh-order Chebyshev low-pass filter. By loading on the designed pattern is realized. filter was applied to feed line, were reduced in section separate operating band remove generated by proposed antenna. simulated S11 ...

Bow-tie diagrams are emerging as a very useful tool to depict and maintain an up-to-date, real-time, working risk management system embedded in daily operations. They are a proven concept in the worldwide offshore industry. These diagrams provide a pictorial representation of the risk assessment process. This article introduces the bow-tie concept to the downstream and chemical process industri...

Exploring the structural topology of genome-based large-scale metabolic network is essential for investigating possible relations between structure and functionality. Visualization would be helpful for obtaining immediate information about structural organization. In this work, metabolic networks of 75 organisms were investigated from a topological point of view. A spread bow-tie model was prop...
