Abstract: As an important part of the spaceborne radar system design, the beam position design has a great impact on subsequent ship detection performance in a spaceborne marine moving target ...

When Mazda debuted the compact Mazda3 in the early 2000s as a replacement for the Protege, the car quickly earned praise for being one of the best-handling, most driver-focused cars in its class, and ...

For the first few decades of the 20th century, pickup trucks were pretty primitive machines. Spartan cabs with little in the way of creature comforts, simple, torquey drivetrains, and solid axle front ...

The digit portions were mapped to steel, while the remaining portions were mapped to concrete. Figure illustrates the relationship between the proportion of steel in the cross-section and the strength ...

Abstract: For high-speed train (HST) millimeter wave (mmWave) communications, the use of narrow beams with small beam coverage needs frequent beam switching, while wider beams with small beam gain ...

CompoTech PLUS (Sušice, Czech Republic) uses its proprietary advanced fiber laying (AFL) and winding technologies to replace steel and aluminum with lightweight carbon fiber-reinforced polymer (CFRP) ...

This paper describes the application of metal Big Area Additive Manufacturing (mBAAM) to the fabrication of a machine tool cross beam. The replacement of a traditional box design weldment with a new ...

Physik Instrumente’s S-335 two-axis fast steering mirrors with PICMA piezo actuators aim to be the benchmark for laser beam steering in high-speed applications. Ceramic encapsulated PICMA piezo ...

First, the payload requirements and problems faced by traditional multi-beam antenna are described. The user beam of the VHTS payload system mainly uses Ka-band multi-beam antenna for a large range of ...
