A method is presented for automated segmentation of vessels in two-dimensional color images of the retina. This method can be used in computer analyses of retinal images, e.g., in automated screening ...

Photovoltaic (PV) energy has grown at an average annual rate of 60% in the last five years, surpassing one third of the cumulative wind energy installed capacity, and is quickly becoming an important ...

We report a novel three-segmented fiber-collimator using self-assembled fluorinated polymer lens and a beam expanding coreless silica fiber of 200-μm diameter spliced to single-mode optical fiber.

A multilayer radar-absorbing structure with plasma- and radar-absorbing material (RAM) is established to investigate the stealth mechanisms of the multilayer absorber. The method of impedance ...

The performance of copper indium gallium diselenide (CIGS) thin film solar cell has been numerically simulated with different buffer and absorber layers thickness. The cell structure based on CIGS ...

String matching has sparked renewed research interest due to its usefulness for deep packet inspection in applications such as intrusion detection, virus scanning, and Internet content filtering.

This article presents a four-level pulse-amplitude modulation (PAM4) quarter-rate clock and data recovery circuit (CDR). A quarter-rate linear phase detector (QLPD) is proposed to reduce the recovered ...

In this paper a strong Lyapunov function is obtained, for the first time, for the super twisting algorithm, an important class of second order sliding modes (SOSM). This algorithm is widely used in ...

A wheeled-type pipe inspection robot designed to work in 300 to 500 mm diameter pipe with multiple elbows is introduced in this paper. The robot consists of two modules-active module and passive ...

Book Abstract: This advanced text and reference covers the design and implementation of integrated circuits for analog-to-digital and digital-to-analog conversion. It begins with basic concepts and ...

Besides attracting a billion dollar economy, Bitcoin revolutionized the field of digital currencies and influenced many adjacent areas. This also induced significant scientific interest. In this ...

Network-on-Chips (NoCs) are becoming integral parts of modern microprocessors as the number of cores and modules integrated on a single chip continues to increase. Research and development of future ...
