Developed by Ansoft in 1990, the High Frequency Structure Simulator (HFSS) has become the simulator of choice for the electromagnetics design of complex threedimensional microwave devices. HFSS has been used to design thousands of microwave devices more quickly and reliably than is possible with prototypes alone. This broad use has generated considerable user feedback and customer requests for ...

The Range Limited Antenna (RLA) is a device, which accurately estimates the range of incoming signals and rejects those that arrive from outside a certain, pre-determined range. This task is accomplished by using two multi-element arrays and applying direction finding (DF) algorithms on each of them. Rectangular, single-layer, coax-fed patch antennas are used as array elements for the specific ...

Thus far, the adoption of hydrogen fuel cell vehicles (HCEVs) has been hampered by lack fueling infrastructure. This study aimed to determine optimal location and prioritization stations (HFSs) in Seoul utilizing a multi-standard decision-making approach optimization method. HFS candidate sites were evaluated with respect relevant laws regulations. Key factors such as safety, economy, convenien...

The objective of this study was to explore the impact of different advertising messages on adults' snack choice. Eighty participants (18-24 years old) were offered the choice between two snack packs following exposure to one of three advertising conditions. The snack packs contained either healthy or high fat, sugar or salt (HFSS) foods. Participants were exposed to commercials containing eithe...

The representation of spatially moving entities is commonly achieved using publish/subscribe communication (PSC) supported by some frameworks, like the High Level Architecture (HLA). PSC, however, can become complex and inefficient since it requires the definition of regions of interest and/or it generates false positive messages that need to be filtered and discarded, impacting negatively simu...

A 3D full-wave approach, based on the Foldy-Lax multiple scattering equations, is successfully extended to model massivelycoupled multiple vias using differential signaling and shared antipad in high speed vertical interconnects. For the first time, this method has been used and tested on via-pair with shared antipad in multilayered structure. The magnetic frill current source on the port is ca...

Moreover, Zhu et al. [11], developed dual hesitant fuzzy sets (DHFSs) as a new extension of HFSs. The DHFS is a comprehensive set encompassing several existing fuzzy sets with certain conditions, whose membership and nonmembership are represented by a set of possible values respectively. In particular cases, DHFSs can reduce to some existing fuzzy sets, such as FSs, IFSs, HFSs and FMSs. From a ...
