An efficient method to reduce CO2 concentration. Climate change is one of the most urgent subjects worldwide, with implications affecting the entire population of the planet. One of the major aspects influencing global warming is the emission of greenhouse gases to the atmosphere. Most of the greenh.....

A robust method of identifying moving or changing objects in a video sequence groups each pixel with other adjacent pixels according to either motion or intensity values. Pixels are then repeatedly regrouped into clusters in a hierarchical manner. As these clusters are regrouped, the motion pattern .....

Carrier Recovery (CR) is a critical component in modern digital signal processing (DSP) oriented coherent receivers for 100-400G transmission and beyond. Multiple carrier phase estimation (CPE) methods have been heretofore considered for Quadrature Phase-Shift Keying (QPSK) transmission. One of the .....

Laser frequency can be converted very efficiently nowadays using electrically field poled ferroelectric crystals, such as LiNbO3 or KTiOPO4. Unfortunately, these crystals are readily available only with relatively small aperture – up to 1 mm in the critical Z axis of the crystal – thereby severely l.....
