WIDE VIEW DSA SYSTEM USING TABLE STEP SHIFT MECHANISM

A Wide-Angle View Endoscope System Using Wedge Prisms

We describe a novel robotic endoscope system. It can be used to observe a wide area without moving or bending the endoscope. The system consists of a laparoscope with zoom facility and two wedge prisms at the tip. This new concept produces excellent characteristics as follows. Firstly, it can change the field of view even in a small space. Secondly, it is safe because it avoids the possibility ...

Antivirus performance characterisation: system-wide view

Cyber security threats are still big concerns of the cyber world. Even though many defense techniques have been proposed and used so far, the antivirus (AV) software is very widely used and recommended for the end-usersPC community. Most effective AV products are commercial and thus competitive and it is not obvious for security researchers or system developers how exactly the AV works or how i...

Foveated, wide field-of-view imaging system using a liquid crystal spatial light modulator.

The field-of-view (FOV) of a simple imaging system can be dramatically improved using a liquid crystal spatial light modulator (SLM). A SLM can be used to correct the off-axis aberrations that often limit the useful FOV of an imaging system giving near diffraction-limited performance at much larger field angles than would otherwise be possible. Foveated imaging refers to the variation in spatia...

AdiosStMan: Parallelizing Casacore Table Data System Using Adaptive IO System

In this paper, we investigate the Casacore Table Data System (CTDS) used in the casacore and CASA libraries, and methods to parallelize it. CTDS provides a storage manager plugin mechanism for third-party developers to design and implement their own CTDS storage managers. Having this in mind, we looked into various storage backend techniques that can possibly enable parallel I/O for CTDS by imp...
