Fused Filament Printing Process
Additive manufacturing technologies are used in various high-tech industries. Additive methods for the production of prostheses, implants and other products of complex geometric shapes made of polymer materials are being actively studied and introduced. A large number of studies are associated with the use of polylactide (PLA), polyether ether ketone (PEEK), polyamides and other biocompatible materials when printing using fused filament/granular fabrication (FFF/FGF).

Fusil Automatique Modèle 1917
The Fusil Automatique Modèle 1917 (English: Model 1917 Automatic Rifle) (also called the RSC M1917 ) was a gas-operated, semi-automatic rifle that the French Army placed in service during the latter part (1917) of World War I. It was chambered in then-standard 8mm Lebel, the rimmed cartridge used in other French Army infantry weapons of the time. Altogether, the French National Armories (primarily MAS (Manufacture d'Armes de St Etienne) and MAT (Manufacture d'Armes de Tulle) had manufactured 86,000 RSC M1917 rifles when their production run ended in late November 1918. However very few have survived in fully functional, semi-automatic condition and those have become highly sought-after collectibles.

Fusion of 3D Ultrasound Hand-Geometry and Palmprint
Multimodal biometric systems are often used in a wide variety of applications where high security is required. Such systems show several merits in terms of universality and recognition rate compared to unimodal systems. Among several acquisition technologies, ultrasound bears great potential in high secure access applications because it allows the acquisition of 3D information about the human body and is able to verify liveness of the sample.

Fusion of Knowledge Graphs into Cognitive Modular Production
Modular production has been recognized as a pivotal approach for enhancing productivity and cost reduction within the industrialized building industry. In the pursuit of further optimization of production processes, the concept of cognitive modular production (CMP) has been proposed, aiming to integrate digital twins (DTs), artificial intelligence (AI), and Internet of Things (IoT) technologies into modular production systems. This fusion would imbue these systems with perception and decision-making capabilities, enabling autonomous operations. However, the efficacy of this approach critically hinges upon the ability to comprehend the production process and its variations, as well as the utilization of IoT and cognitive functionalities. Knowledge graphs (KGs) represent a type of graph database that organizes data into interconnected nodes (entities) and edges (relationships), thereby providing a visual and intuitive representation of intricate systems.

Fuzzy Algorithms in Multi-Motor Systems
Multi-motor systems are strong coupled multiple-input–multiple-output systems with independent or mechanically interconnected motors. The main objective in multi-motor drive control is to achieve synchronized operation of all motors in the system. In this paper, multi-motor systems are classified in accordance with their control demands. The review of recent research literature indicates that fuzzy algorithms are widely used in multi-motor control.

Fuzzy-Based Efficient Healthcare Data Collection in the IoMT
The Internet of Things (IoT) is an advanced technology that comprises numerous devices with carrying sensors to collect, send, and receive data. Due to its vast popularity and efficiency, it is employed in collecting crucial data for the health sector. As the sensors generate huge amounts of data, it is better for the data to be aggregated before being transmitting the data further. These sensors generate redundant data frequently and transmit the same values again and again unless there is no variation in the data.

FYFT A-Series Unmanned Blimp
FYFT A-series unmanned blimps are Chinese UAVs developed by Qingdao Fei-Yu (meaning Flying Universe) Aviation Science and Technology Co., Ltd. (FYFT, 青岛飞宇有限公司), and these unmanned blimps are named after their respective length. For example: if an A1 series blimp is 11 meter long, then it is named A1-1100, because 11 meters is equal to 1100 centimeters.
