Boom Technology Overture
The Boom Technology Overture is a Mach 2.2 (1,300 kn; 2,300 km/h), 55-passenger supersonic transport with 4,500 nmi (8,300 km) of range, which is proposed to be introduced in 2025–2027 by Boom Technology. With 500 viable routes, there could be a market for 1,000 supersonic airliners with business class fares. It had gathered 76 commitments by December 2017. It would keep the delta wing configuration of Concorde but would be built with composite materials. It would be powered by three dry 15,000–20,000 lbf (67–89 kN) turbofans, a derivative or a clean-sheet design were to be selected in 2019.

Bose Wave System
Bose Corporation's Wave Music Systems are table top audio systems which were first released in 1984. Various Wave systems comprise CD players, DAB tuners and inputs for computer sources, and in addition most models contain an AM/FM tuner. Wave systems use a folded waveguide (a series of passages from the speaker driver to the speaker grill), in an attempt to replicate sound from larger systems in a compact design. Bose claims the waveguide "produces full, clear stereo sound from a small enclosure by guiding air through two 26” folded wave guides". In 1987, Amar G. Bose and William R. Short won the Intellectual Property Owners Education Foundation's Inventor of the Year award for the waveguide loudspeaker system.

Bottom Ash Waste Management in Building Industry
MSWIBA development fits into the European Green Deal, Sustainable Development Goals (SDGs), and the Circular Economy (CE). The combustion of MSW in incineration plants generates more than 30% of secondary waste concerning the inlet stream. The main residue is MSW incineration bottom ash (MSWIBA), which accounts for ca. 90% of MSW incineration solid residues.

Bounding Box Based Perception Modules
Perception modules use raw data streams obtained from sensors mounted on car like camera, radar or lidar devices to recognize and interpret the surroundings. Raw data collected by sensors must be properly interpreted and processed to be understood by computer. This type of analysis is carried out by algorithms supported mainly by many trained neural networks (detectors). Most perception modules based on computer vision systems use bounding boxes to mark the recognized objects in each separate frame of the video stream.

Bowdoin (Arctic Schooner)
The schooner Bowdoin /ˈboʊdɪn/ was designed by William H. Hand, Jr., and built in 1921, in East Boothbay, Maine, at the Hodgdon Brothers Shipyard now known as Hodgdon Yachts. She is the only American schooner built specifically for Arctic exploration, and was designed under the direction of explorer Donald B. MacMillan. She has made 29 trips above the Arctic Circle in her life, three since she was acquired by the Maine Maritime Academy in 1988. She is currently owned by the Maine Maritime Academy, located in Castine, Maine, and is used for their sail training curriculum. She is named for Bowdoin College.

Brackish Water Reverse Osmosis Desalination
Brackish water desalination, using the reverse osmosis (BWRO) process, has become common in global regions, where vast reserves of brackish groundwater are found (e.g., the United States, North Africa).

Braid Hollow Fiber Membranes
Hollow fiber membranes (HFMs) are a good candidate for the membrane separation process due to desirable properties such as high permeability and surface area, good filtration efficiency, small footprint, etc. However, they are often possible to break during the high-pressure cleaning and aeration process. Tubular braids a supported is proposed to improve the mechanical strength of HFMs due to high tensile strength.

Brain Stroke Monitoring
Stroke is a medical disease that affects millions of people worldwide per year, which leads to permanent disabilities or even death. It occurs when the regular flow of rich-oxygen blood through a brain vessel is interrupted due to a clot or a burst of it, triggering the death of brain cells and requiring prompt diagnosis and intervention after its onset to improve the prognosis significantly. The two main types of stroke are hemorrhagic and ischemic ones.

Brain-Inspired Robot Control
Multifunctional control in real time is a critical target in intelligent robotics. Combined with behavioral flexibility, such control enables real-time robot navigation and adaption to complex, often changing environments. Multifunctionality is observed across a wide range of living species and behaviors. As made clear above, even seemingly simple organisms such as invertebrates demonstrate multifunctional control. Living systems rely on the ability to shift from one behavior to another, and to vary a specific behavior for successful action under changing environmental conditions. Truly multifunctional control is a major challenge in robotics. A plausible approach is to develop a methodology that maps multifunctional biological system properties onto simulations to potentiate rapid prototyping and real-time simulation of solutions (control architectures).
