Fast and Power Reduced RNS-Based Image Filtering in Spatial Domain

This paper presents a fast and power reduced design for digital image filtering. Contrary to the typical designs for image processing, this one is based on a non-weighted number system, residue number system (RNS). The proposed structure applies a number of spatial filters on ...

Waffle MOS channel aspect ratio calculation with Schwarz-Christoffel transformation

The main goal of this work is to describe alternative way of effective channel width to length (W/L) ratio calculation for Waffle MOS structure. Due to non-conventional gate geometry of the Waffle MOS transistor compare to the fingers structure, the channel W/L ratio calc...

More Complex Polymorphic Circuits: A Way to Implementation of Smart Dependable Systems

Today, there are a lot of application areas, where a circuit, which is able to perform different functions in different situations, may be useful. Typically, polymorphic circuits provide very area-efficient implementation and have also embedded and distributed sensing of an environment state...

Comparison of Rosin Fluxes

This article will present results of activity testing of rosin fluxes. A good solderability of a component output and a soldering pad of PCB are important for the creation of a quality joint. Since it supports a melted solder wetting on a soldered surface, a flux has...

Substrate Preparation for Manufacturing of Aluminum Nitride Layers

Aluminum nitrides layers prepared on sapphire substrates are examined. The substrate surface was treated by dry plasma etching. The morphology of aluminum nitride thin films was studied by atomic force microscopy. Lateral force atomic force microscopy was used to study the morphology he...

Stability of galvanomagnetic properties of CdTe in the range 30-100%

The thermal stability of p-type CdTe crystals by using conductivity and Hall-effect measurements have been studied at room and slightly increased temperatures. Different types of thermal relaxation were observed for two p-type samples, which differed in the character and in the rate of&...
