Acoustic Performance-Based Design
Current development in digital design, combined with the growing awareness of the importance of building performance, had drawn attention to performance-based design (PBD) in architecture. PBD benefits both design workflow and outcome, allowing one to control the performance of the design proposal since early design phases.

Acoustic Technology in Food Processing
Acoustic technology is characterized as environmentally friendly and is considered an alternative method due to its sustainability and economic efficiency. This technology provides advantages such as the intensification of processes, increasing the efficiency of processes and eliminating inefficient ones, improving product quality, maintaining the product’s texture, organoleptic properties, and nutritional value, and ensuring the microbiological safety of the product.

Acrylic Bone Cements
Acrylic bone cements (ABC) are widely used in orthopedics for joint fixation, antibiotic release, and bone defect filling, among others. Most of the commercial ABCs available today consist of two components, one solid, based mainly on poly(methyl methacrylate) (PMMA), and one liquid, based on methyl methacrylate (MMA), which are mixed and, through the polymerization reaction of the monomer, transformed into a hardened cement paste.

Active Aerodynamic Systems for Road Vehicles
Comfort, safety, high travel speeds, and low fuel consumption are expected characteristics of modern cars. Some of these are in conflict with one other. A solution to this conflict may be time-varying body geometry realized by moving aerodynamic elements and appropriate systems for controlling their motion.

Active Design
Active Design is a set of building and planning principles that promote physical activity. Active design in a building, landscape or city design integrates physical activity into the occupants' everyday routines, such as walking to the store or making a photocopy. Active design involves urban planners, architects, transportation engineers, public health professionals, community leaders and other professionals in building places that encourage physical activity as an integral part of life. While not an inherent part of active design, most designers employing "active design" are also concerned with the productive life of their buildings and their building's ecological footprint.

Active Design Approach Affect the Environmental Psychology
The growing urban population has increased environmental demands and affects human health due to the rise of chronic diseases caused by populations’ inactivity. A new design trend introduced by scientists and researchers for solving this issue is the active design approach. Built environments that were expressly designed to improve physical activity correlated to higher rates of physical activity, which in turn, positively affects health.

Active Distribution Networks with Fault Current Limiters
To cope with the increasing energy demand, power systems, especially distribution networks, face many challenges. These networks have become complex and large, and their stability and reliability are not easy to be handled. The integration of renewable energy resources and at the same time limiting their accompanied high fault currents is one of the approvable suggestions. Many solutions have appeared to restrict the fault currents, but fault current limiters (FCLs) arise as an efficient and promising solution to whether to interrupt or limit the fault currents to allowable limits.

Active Front-End Rectifiers in EV DC Charging Applications
Active Front-End (AFE) rectifiers have regained momentum as the demand for highpower Electric Vehicle (EV) charging infrastructure increases exponentially. AFE rectifiers have high efficiency and reliability, and they minimize the disturbances that could be generated due to the operation of the EV charging systems by reducing harmonic distortion and operating close to the Unity Power Factor (UPF).

Active Noise Control Technology
Reducing noise radiation via passive control may have adverse effects on the aerodynamic performance. Therefore, an alternative approach is to design the vehicle with some passive control built-in the design, which should be optimized for regular flight operations then engage active noise control (ANC) only in particular situations when the noise temporarily increases above the allowable level as in the vicinity of vertiport.
