We have designed and constructed a Fourier Transform Spectrometer (FTS) for the study of submillimeter-wave mixers and optical components. The FTS has a large aperture (up to 25.4 cm) and small focal ratio (as fast as f/2.5) to achieve a large throughput. It operates in the 100-3750 GHz (3.3-125 cm ?1) frequency range with a resolution of up to 75 MHz (0.0025 cm ?1). Here we discuss the design ...

A Bit-Mixer is a function of fixed size input and output, which computes uncorrelated output from correlated input values, and its behavior is altered by parameters, called keys. Several bit-mixer constructions have been published with very fast, power efficient implementations in electronic hardware, having very little side channel leakage. In this paper a dozen cryptographic applications are ...

The flotation circuit in Sungun copper plant consists of two column flotation cells as cleaner, having fixed-spargers system. To achieve the expected aims in flotation step, there are serious operational challenges such as: fast choking of the static mixers, boiling problem, burping phenomena and pulp overflow to concentrate lander, maintenance and control problems. An attempt was exerted by im...

This review article revisits the role of static mixers in process industry nowadays and summarizes most relevant developments literature available on this type handling liquid-phase systems. In particular, seeks to discuss depth progress that has been made hydrodynamic understanding immiscible liquid–liquid dispersions emulsion formation using motionless types mixers, both through experimental ...

The balanced mixer is fabricated on a 2 x 1 mm quartz substrate which contains an RF quadrature hybrid and two SIS mixers. These components are realized in capacitively-loaded coplanar waveguide, which minimizes stray coupling between adjacent components and coupling to undesired modes in the thick quartz substrate. Signal and LO waveguides are coupled to separate ports of the main substrate vi...

A novel approach toward the needs of a versatile chip-based microfluidic system with unique properties and functionality is reviewed. Like for microarrays and in contrast to many existing technologies, the fluid handling is performed on the flat surface of a programmable chip, where fluidic tracks and functional blocks such as valves, dispensers, mixers, and sensing elements are chemically defi...

Efficient models based on behavioural modelling techniques are needed for RF and microwave mixers in order to check the performances of communication systems. Here, we propose a model consisting on the cascade connection of an input equivalent filter, characterising the linear transmission and reflection memory effects, and an ideal nonlinear mixer model, providing the frequency translation and...
