Bolted joints are among the most common structural elements in precision machinery. They are used because they are strong, serviceable and reliable. Yet, despite their prevalence, the moment stiffness ...

Abstract: In this paper, a composite anti-disturbance control method is proposed for electromechanical fin actuators with deflection angle constraints and multiple disturbances. Firstly, a ...

For the past few months, I’ve been introducing what’s probably a new concept to most people in the bending department: Using a 3D printer to make press brake tooling (see Figure 1). This month, let’s ...

The Supporting Information is available free of charge at https://pubs.acs.org/doi/10.1021/acs.cgd.5c01062. It includes FT-IR and 1 H NMR spectra of the hydrazones ...

Hamza is a gaming enthusiast and a Writing Specialist from Pakistan. A firm believer in Keyboard/Mouse supremacy, he will play Tekken with WASD if you let him. He has been writing about games since ...

In weak field limits, we compute the deflection angle of a gravitational decoupling extended black hole (BH) solution. We obtained the Gaussian optical curvature by examining the null geodesic ...

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 ...

Auburn, MA – The S-335 fast steering mirror (FSM) provides fast and high-resolution motion in two degrees of freedom. Based on solid-state piezo drives, it is well-suited for precise, high-speed laser ...

Active metadevices integrated with semiconductors. (a) Hybrid silicon-metallic resonators for all-optical ultrafast active metamaterials. (b) Broadband metamaterial frequency switch with femtosecond ...

These optical scanners comprise two separate, perpendicular planar mirrors that rotate independently. They are positioned in a manner wherein laser light bouncing off the first mirror (axis 1) ...
