A timing discriminator design for space flight delay line image systems is presented. This discriminator processes delay line signal pulses having a few ns width and recovers event timing centroids with an accuracy better than 100 ps full width at half maximum. For space flight use, it is important to minimize parts count and power consumption. Because it is difficult or impossible to adjust eq...

Tactical Data Link (TDL) is a communication system that utilizes particular message format and protocol to transmit data via wireless channels in an instant, automatic, secure way. So far, TDL has shown its excellence military applications. Current adopts distributed architecture enhance anti-destruction capacity. However, It still faces problem of inconsistency thus cannot well support coopera...

The present article describes a reverberation instrument which is based on cognitive categorization of reverberating spaces. Different techniques for artificial reverberation will be covered. A multidimensional scaling experiment was conducted on impulse responses in order to determine how humans acoustically perceive spatiality. This research seems to indicate that the perceptual dimensions ar...

El trastorno específico del lenguaje (TEL), también denominado como desarrollo (TDL), se presenta en la población a través de dificultades severas comprensión y/o expresión que afectan su calidad vida y suponen una barrera progresión académica el acceso laboral. reciente cambio conceptualización diagnóstico contexto anglosajón hacia concepto TDL2 (Bishop, Snowling, Thompson, Greenhalgh, Catalis...

A circuit is described which develops time-invariant pulses for large scintillation trigger counters. For a 8.56 ft long counter, a unit capable of f 22 nsec range is described; the constancy of delay of output for this unit over the full delay range is typically & 400 psec. * Work supported by the U. S. Atomic Energy Commission. (Submitted to Nucl. Instr . & Methods. ) 1 D Introduction One of ...

After intravenous injection into rats, both the attenuated strain R1Rv and the virulent strain H37Rv of Mycobacterium tuberculosis grow in the liver and spleen. However, the infected rats mount a specific immune response with great rapidity, giving a false impression of natural resistance to the tubercle bacillus. Adoptive immunity to tuberculosis was achieved by transferring thoracic duct cell...

In recent years, an increasing number of research projects investigated whether the central nervous system employs internal models in motor control. While inverse models in the control loop can be identified more readily in both motor behavior and the firing of single neurons, providing direct evidence for the existence of forward models is more complicated. In this paper, we will discuss such ...
