Resonator based switching technique between ultra wide band (Uwb) and single/dual continuously tunable-notch behaviors in uwb radar for wireless vital signs monitoring
( MDPI AG , 2018 , Article)This paper presents a novel resonator that can switch and create three important behaviors within the same antenna using miniaturized capacitors. The resonator was integrated into conventional Ultra-Wide Band (UWB) antenna ... -
Rheological and mechanical behavior of silk fibroin reinforced waterborne polyurethane
( MDPI AG , 2016 , Article)Waterborne polyurethane (WPU) is a versatile and environment-friendly material with growing applications in both industry and academia. Silk fibroin (SF) is an attractive material known for its structural, biological and ... -
Road users' behavior at marked Crosswalks on channelized right-turn lanes at intersections in the state of Qatar
( MDPI AG , 2019 , Article)At non-signalized marked crosswalks, pedestrian priority is neither well-defined nor well acknowledged by drivers. This paper presents the findings of an investigation on both driver and pedestrian behavior at non-signalized ... -
Rupture of an industrial gfrp composite mitered elbow pipe
( MDPI AG , 2021 , Article)This paper examines the immature rupture of glass fiber reinforced plastic composite (GFRP) mitered elbow pipes. The GFRP composite mitered elbow pipe’s lifespan was twenty-five years; however, the pipes in question ... -
Sandwich structures for energy absorption applications: A review
( MDPI AG , 2021 , Article)It is crucial that proper engineering structures are designed as energy absorbers for high dynamic loading situations, such as accidents, blasts, or impacts. The role of such structures is to absorb the high kinetic energy ... -
Study of mild steel sandwich structure energy absorption performance subjected to localized impulsive loading
( MDPI AG , 2020 , Article)Extensive research focus had been given to sacrificial sandwich panels to mitigate the effects of blast loads. This is due to their ability to distribute the load and absorb a significant portion of the blast energy. This ... -
Surface alloying in silver-cobalt through a second wave solution combustion synthesis technique
( MDPI AG , 2018 , Article)Herein, we report the synthesis of silver-cobalt nanopowders using three different modes of solution combustion synthesis, and we present the effects of the synthesis conditions on particle morphology. The synthesized ... -
The design of green supply chains under carbon policies: A literature review of quantitative models
( MDPI AG , 2019 , Article Review)Carbon footprinting of products and services is getting increasing attention due to the growing emphasis on carbon related policies in many countries. As a result, many enterprises are focusing on the design of green supply ... -
Wearable real-time heart attack detection and warning system to reduce road accidents
( MDPI AG , 2019 , Article)Heart attack is one of the leading causes of human death worldwide. Every year, about 610,000 people die of heart attack in the United States alone—that is one in every four deaths—but there are well understood early ...
