Spatial variations of rain intensity over a short length propagation for 5G links based on a rain gauge network
Millimeter-wave (mm-wave) frequency range is among operating bands
designated for terrestrial 5G networks. A critical challenge of link-budgeting
in mm-wave 5G networks is the precise estimation of rain attenuation for
short-path links. The…

Analytical determination of load resistance value for MQ-series gas sensors: MQ-6 as case study
The MQ-series gas sensors are attractive candidates in the area of gas
concentration sensing due to their high sensitivity and low cost. Even though
the sensor circuit sensitivity and sensor power dissipation level both depend
on load resistance,…

Aluminum based nanostructures for energy applications
The plasmonic material properties of aluminum allow active plasmon
resonances extending from the blue color in the visible range to the ultraviolet
(UV) region of the spectrum. Whereas Al is usually avoided for applications
of plasmonics due to…

Design of UWB microstrip patch antenna with variable band notched characteristics
Recently lower frequency band 4.5 − 5.5 GHz is proposed by the ASEAN
countries for 5G cellular application and therefore, it is essential of designing
an ultra-wideband (UWB) antenna for the particular band-notched
characteristics. In this…

Effects of humidity on sand and dust storm attenuation predictions based on 14 GHz measurement
Several models were proposed to predict the attenuation of microwave signals
due to sand and dust storms. Those models were developed based on
theoretical assumptions like Rayleigh approximation, Mie equations or
numerical methods. This paper…

Adopting explicit and implicit social relations by SVD++ for recommendation system improvement
Recommender systems suffer a set of drawbacks such as sparsity. Social
relations provide a useful source to overcome the sparsity problem. Previous
studies have utilized social relations or rating feedback sources. However, they
ignored…
