Abstract:
The increased interest in vacuum tube audio amplifiers led to an increased interest in mathematical modelling of such kind of amplifiers. The main purpose of this paper is to develop a novel global numerical approach in calculation of the harmonic distortion (HD) and intermodulation distortion (IM) of vacuum-triode audio amplifiers, suitable for applications using brute-force of modern computers. Since the 3/2 power law gives only the transcharacteristic inverse of a vacuum triode amplifier, unknown plate currents are determined in this paper iteratively using Newton’s method.

Abstract:
High-voltage insulation space-components are critical to the reliability of traveling wave tube amplifiers on satellite. Unlike in atmosphere, high-voltage components working in space can easily discharge due to insulation molding defects, which will lead to failure of amplifiers. We can solve these problems through adopting epoxy resin matrix composites as filler and applying vacuum-pressure injection molding technology for insulated molding process.

The past century has seen the ongoing development of amplifiers for different electrophysiological signals to study the work of the heart. Since the vacuum tube era, engineers and designers of bioamplifiers for recording electrophysiological signals have been trying to achieve similar objectives: increasing the input impedance and common-mode rejection ratio, as well as reducing power consumption and the size of the bioamplifier.

Vacuum tube amplifiers present sonic characteristics frequently coveted by musicians, that are often due to the distinct nonlinearities of their circuits, and accurately modelling such effects can be a challenging task. A recent rise in machine learning methods has lead to the ubiquity of neural networks in all fields of study including virtual analog modelling. This has lead to the appearance of a variety of architectures tailored to this task.

Abstract:
An experimental, field replaceable travelling wave tube (TWT) with low profile, TEM transitions has been developed with the aim of combining the cost advantages of field replaceable TWTs with the bandwidth advantages of TEM transitions. Field replaceable TWTs are cheaper because their periodic permanent magnet (PPM) stacks (which are expensive) are easier to produce and can be reused. Standard TEM transitions have a high profile and prevent TWTs from being plugged into PPM stacks. The stacks of packaged TWTs are therefore built onto the tubes, using split ring magnets, before the tubes are pot

Abstract:
During the first half of the twentieth century, before the availability of computerized literature searches, scientists who were working independently often discovered similar measures, phenomena, or relationships. The electrogastrogram (EGG) was discovered independently by at least three investigators: Walter Alvarez, a gastroenterologist; I. Harrison Tumpeer, a pediatrician; and R. C. Davis, a psychophysiologist. On October 14, 1921, after considerable experimentation with rabbits at the University of California in San Francisco, Walter Alvarez recorded the first human EGG. Figure 1.1 shows this EGG, which was recorded from an elderly woman with an abdominal wall hernia. The woman was so thin that Alvarez could observe gastric contractions of 3 min in the upper abdomen that corresponded to the 3cycles/min (cpm) electrical waves that are clearly seen in the EGG recording. Alvarez did not publish additional studies with the EGG during his long and productive career, probably because of the technical difficulties inherent in recording such a weak signal before the development of good vacuum tube amplifiers. I. Harrison Tumpeer, a pediatrician working at Michael Reese Hospital in Chicago, reported in 1926 that while he was attempting to record the EGG, “Alvarez of California published his results.” In a subsequent publication, Tumpeer successfully recorded the EGG from a 5-week-old child who had pyloric stenosis. Tumpeer and his coworkers selected this particular subject because they could observe gastric contractions by simply watching the surface of the skin over the abdomen. Figure 1.2 shows a portion of this EGG. Tumpeer described the EGG as looking like an electrocardiogram (EGG) with a slowly changing baseline. Tumpeer mentioned that cardiologists in 1926 often noted a changing baseline in EGG recordings that they could not explain. Thus, the EGG had been recorded, but perhaps not recognized as such, since the time of the first EGG at the turn of the twentieth century. Tumpeer used limb leads to record his EGG (not abdominal leads) because of his concern that each gastric contraction caused physical displacement of the skin over the child's abdomen. Subsequent studies showed that simultaneous recordings from limbs and abdomen are similar except that the amplitude of the EGG is greatly reduced from recordings from the limb leads.

Abstract:
I remember with some precision when I began believing that there is nothing so complex that a reasonably intelligent person cannot comprehend it. It was a summer day, when I was 15 or 16, and my best friend, Ron Light, and I decided that we wanted to understand how a guitar amplifier works. We both played in a mediocre I96os-era garage band. While Ron went on to become a fairly accomplished guitarist, I was slowly learning that any talent I had didn't lie within the realm of music. Already the aspiring little scientist, I was able to learn enough of the logic of basic harmony theory to execute the mindlessly simple algorithms called bass riffs, and if pressed I could even fire off a bass solo, the dread of concertgoers everywhere. But my approach to the performance was purely intellectual. I didn't have rhythm, or maybe soul. Poring over the symbols on the circuit diagram of Ron's Fender Deluxe Reverb amplifier seemed infinitely more interesting than trying to read music. I wanted to know what that impressively convoluted blueprint really meant, how electricity flowing through the labyrinth of wires and components could cause the tiny vibration of a guitar string to be multiplied so many times that it rocked the walls of the living room, inciting the neighbors to call the police. This was still the era of the vacuum tube, before those glowing glass envelopes were replaced by coldly efficient transistors and microchips. Electronics was pretty simple to understand. I had already learned some basics from The Boys' Second Book of Radio and Electronics and the guide for the Boy Scout electricity merit badge (the colorful embroidered patch was decorated with a human fist clutching zigzag lightning bolts). In a typical circuit, there were resistors that, true to their calling, resisted electricity, pinching the flow of electrons. There were capacitors, also aptly named, that stored electrical charges. There were tightly wound coils of copper wire called inductors that would hold energy in the form of electromagnetic fields. Finally, there were the vacuum tubes themselves, mysterious pockets of illuminated nothingness inside of which the actual amplification took place.
