Features in Interdigitated Electrode Array
The electrical double layer (EDL) and crucial parameters such as sensitivity, selectivity, specificity, and limit of detection (LOD) are prominent to determine the interdigitated electrode array (IDEA)-based electrochemical sensor. The design of IDEA focuses on controlling the width and gap measurements between the adjacent fingers and increases the IDEA’s height are crucial because all the design measurement and parameters affected the IDEA-based electrochemical sensor functionality according to the application usage.

Smart Glasses in Applied Sciences
Smart glasses are a type of wearable device that can be worn on the face, and they meet the original objective of enabling clearer vision in addition to functioning as a computer. Since Google released “Google Glass” in 2012, companies such as Sony, Microsoft, and Epson have launched their own smart glass products.

N747PA
N747PA, was the registration of a Boeing 747-121. Also known as Clipper Juan T. Trippe, it was the second 747 ever built. It was purchased by Pan Am in 1970. Following an accident in 1971, the aircraft continued service with Pan Am until its collapse in 1991. It served as a freighter until 1997 when it was used as a source of spare parts. In 2000 it was purchased by a South Korean couple and converted into a restaurant. After laying abandoned for years following the restaurant's failure in 2005, the aircraft was finally scrapped in 2010.

Single-Coil Eddy Current Sensors
The single-coil eddy current sensors (SCECS) constitute a separate and independent branch among the eddy current sensors. The SCECS sensing element is a single current loop that can be inserted into the measuring zone with harsh and extreme conditions. Such simplicity of the SCECS design ensures sensors’ functioning at high temperatures, reaching 1200 °C and more in gas turbines, high linear speeds of the monitored objects, contamination of the measuring medium by fuel combustion products, vibrations, etc. The main application of the SCECS related to the monitoring the dangerous states of the power plants. The sensors and their cluster compositions make it possible to evaluate a wide range of power plants diagnostic parameters, including radial clearances between the blade tips and the stator of the compressor and turbine of the gas-turbine engine, shaft displacements in the radial thrust bearings, the presence of wear particles of friction pairs in oil system, etc.

Sound Trap
A sound trap, also known as a duct silencer, sound attenuator, or muffler, is a special acoustical treatment of Heating Ventilating and Air-Conditioning (HVAC) ductwork designed to reduce transmission of noise through the ductwork, either from equipment into occupied spaces in a building, or between occupied spaces. In its simplest form, a sound trap consists of an baffle within the ductwork. These baffles often contain sound-absorbing materials. The physical dimensions and baffle configuration of sound traps are selected to attenuate a specific range of frequencies. Unlike conventional internally-lined ductwork, which is only effective at attenuating mid- and high-frequency noise, sound traps can achieve broader band attenuation in relatively short lengths. Certain types of sound traps are essentially a Helmholtz resonator used as a passive noise-control device.

Biography
William Friese-Greene
William Friese-Greene (born William Edward Green, 7 September 1855 – 5 May 1921) was a prolific English inventor and professional photographer. He is principally known as a pioneer in the field of motion pictures, creating a series of cameras in the period 1888–1891 with which he shot moving pictures in London. He went on to patent an early two-colour filming process in 1905. His inventions

Airport Service Quality and Overall Satisfaction
The novel coronavirus (COVID-19) outbreak has impacted the aviation industry worldwide. Several restrictions and regulations have been implemented to prevent the virus’s spread and maintain airport operations. To recover the trustworthiness of air travelers in the new normality, improving airport service quality (ASQ) is necessary, ultimately increasing passenger satisfaction in airports.
