The level of signal reflection at an intermediate frequency from SIS-mixer was calculated and experimentally measured. measurement performed for the mixer in operation, namely, it biased by voltage local oscillator applied. It is shown that power coefficient can vary -20 to -3 dB depending on operating point. An experimental method determining impedance supply line proposed tested. Keywords: su...

This paper describes new language resources designed to support research in speaker recognition. It begins with a brief overview of collections protocols, motivates the shift from the Switchboard protocol to the Mixer protocol, summarizes yields from the earliest phase of Mixer collection and then describes more recent phases, yields and expected yields and lessons learned.

drop size distribution in a mixer-settler is an essential design parameter, as obtaining drop size distribution will result in optimum performance of equipment. in this paper for obtaining drop size, several experiments have been performed with a single stage horizontal mixer-settler. a video technique has been used in order to measure the drop size in the mixer-settler with the help of a digit...

Endoderm specification in zebrafish is mediated by the zygotic transcription factors Bon/Mixer, Faust/Gata5, Casanova and Sox17, whose expression is induced by Nodal signalling. Bon/Mixer and Gata5 require Casanova in order to promote endoderm formation and all three factors act upstream of sox17, but it is not clear whether Casanova acts downstream of or in parallel to Bon/Mixer and Gata5. An ...

We present a design of a microfluidic mixer based on hydrodynamic focusing which is used to initiate the folding process (i.e., changes of the molecular structure) of a protein. The folding process is initiated by diluting (from 90% to 30%) the local denaturant concentration (initially 6 M GdCl solution) in a short time interval we refer to as mixing time. Our objective is to optimize this mixe...

We give an unified formulation for deterministic and stochastic global optimization algorithms via initial and boundary value problems for different first and second order dynamic systems. The ensemble is applied to the design of a fast-micro-mixer. The aim is to optimize a given mixer shape in order to reduce its mixing time. The algorithms are compared from their complexity and optimization e...

In this paper we present the design and analysis of a distributed regenerative frequency divider (DRFD) based on a novel distributed single-balanced mixer. Artificial transmission lines are incorporated in the distributed single balanced mixer to absorb the parasitic capacitances. The circuit is realized in a 0.18 μm standard CMOS process. It shows a division by two for an input frequency of 40...

This research aimed to redesign an appliance based on the biomechanical aspects in applied ergonomics. The product chosen for analysis was the household mixer, it is readily found in most homes of several families. The study enabled the identification of several potential risks and proposed biomechanical ergonomic solutions for each. Finally, it was possible to redesign the handle of the mixer,...
