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 ...

The processes to form the compositions of loose materials in centrifugal mixers continuous action have been considered. Based on method discrete elements, a mathematical model movement particles rotor mixer was built, taking into consideration their geometric and physical-mechanical parameters. To assess extent influence these parameters nature particle movement, well-known system differential ...

The use of macrocapsules in self-healing applications offers a potential benefit by carrying larger amount healing agent comparison with microcapsules. However, the application is still limited to paste and mortar levels on lab-scale. This due concern that most capsules might be broken when mixed concrete components. In this study, cementitious tubular were used they considered as partial repla...

Vinyl ester resins are widely used as matrix materials in particle and fiber reinforced composites. Nowadays, particles also preferred micron-sized microstructures to increase the mechanical properties of polymer In this work, vinyl composites with aluminum oxide 1-3 micron dimensions were produced. Mechanical such tensile, 3 point bending, hardness, impact wear specimens prepared investigated....

A study was carried out to evaluate the effect of natural fillers on mechanical properties virgin and waste low density polyethylene. Samples disposable sachet bags were obtained blended with varying percentages polylactic acid, starch, charcoal maleic anhydride (M.A) in a 2 roll-mill mixer compression molded form composites using two-roll mix molding machine for compounding. cut according ASTM...
