The patterns of syllable duration in English

We report here some preliminary results from a large study of English speech rhythm. Adjective-noun phrases with three, four and five syllables (e.g., “bold design,” “poor bystander,” “electronic gear”) were spoken in meaningful sentences with the syllable “ma” substituted for each syllable of the phrase: for example, “bold design” was spoken as “MA maMA.“ The following aspects of the phrases were varied: (a) number of syllables, (b) stress pattern, (c) position of word boundary within the phrases, and (d) position of phrases within sentences. Preliminary results from three of eight talkers show how these variables influenced the “ma” syllable durations. The implications of the results for models of English speech rhythm, especially with regard to isochrony, will be discussed. The validity of the reiterant nonsense speech technique will also be discussed.

Increasing efficiency

As part of a research and development programme, the Royal Aircraft Establishment at Farnborough has been continuously testing components and materials for Concorde. To simulate the calculated extremes of heat, pressure and stress expected in flight from ground level to ten miles high, at twice the speed of sound, A.E.W. Ltd were asked to design and build special test ovens and electronic control gear. Specifying very close limits to tolerance on all aspects of design, the overriding stipulation called for reliability and continuous operation on programmes of 30,000hr (3½ year) duration.

Stroboscopic Shutter for Visually Studying Plasma Oscillations

A military surplus ``Snooperscope'' has been converted into a stroboscopic shutter for the study of plasma oscillations. Some modification of the surplus item plus the adaptation of commercially available electronic gear has given a device with which periodic fluctuations in the light output of a plasma in the frequency range 103 to 106 cps can be stroboscopically ``stopped'' and studied. The electric circuits permit a ``lock on'' to a reference signal obtained from the plasma. In this fashion, the stroboscopic shutter will operate even though the plasma oscillations have a frequency jitter greater than 10%. An example of how the device has been used in an investigation of moving striations is given. Other possible uses in the study of plasmas are suggested.

RADIOPULMONOGRAPHY: A METHOD FOR SIMULTANEOUS ESTIMATION OF REGIONAL LUNG VENTILATION BY TRANSMISSION OF X-RAYS.

In recent years, isotopic and electronic methods have been devised for the estimation of regional lung function (1-7). These methods do not readily lend themselves to routine clinical use since they employ either labeled inert gases (1-3) or complex, laboratory-assembled electronic gear, such as photomultiplier tubes for measuring light emitted by a crystal which is excited by passage of fairly heavy (4, 5) or moderate (6) x-ray dosage through the lungs or x-ray-sensitive cadmium cells (7). Details of instrumentation used in these procedures are scant, so that attempts to reproduce these methods are most difficult. Radiopulmonography utilizes readily available commercial apparatus (figure 1). The source of radiation is an inexpensive, portable, x-ray machine; and the detecting apparatus is a dual scintillation detection system consisting of two matched probes, dual ratemeters, and a dual recorder-equipment available in most clinical radioisotope laboratories. To the writers' knowledge, this type of appara.tus, designed for measuring gamma emission, has not previously been used for the measurement of x-ray emission.

Ultrahigh-temperature electronic transformers: I - Design considerations

Over the past 4 years, military groups have had under development components and accessory parts for electronic equipment destined for ultra-high-temperature and intense nuclear radiation applications. High-speed flight, an approach to miniaturization and reentry problems all promise ambient temperatures for electronic gear as high as 500 C (degrees centigrade). The anticipated launching of a nuclear-powered aircraft introduced the new environmental requirement, nuclear radiation. One of the component developments concerned is for 500 C electronic power transformers and has been sponsored by the Air Force under two contracts, AF33(616)-3623 and AF33(616)-5579. The purpose of this and a companion paper, Part II,1 is to summarize the outcome of this development in a form meaningful to design engineers. Design considerations, the subject of this paper, examines the basis for the selection of materials, their mechanical arrangement, and the calculation of coil temperature rise. Using these essential data, Part II1 then presents a digital computer optimization procedure that yields a minimum-weight transformer design.

Nuclear Radiation Electronic Gear (continued)

Nuclear Radiation Electronic Gear (continued)

Nuclear radiation electronic gear

A survey of the basic principles, characteristics, and limitations of important chemical instruments is reported. The emphasis is on commercially available equipment, and approximate prices are quoted to show the order of magnitude of costs of the various types of design and construction. ( P. C. H.)

Closed circuit television in electrocorticography

1. 1. The use of a closed circuit television unit in electrocorticography and brain stimulation is described. 2. 2. By this means the bulky electronic gear is kept out of the operating room, within easy access of the electroencephalographer. 3. 3. The surgeon has immediately visible an enlarged imaged of the continuous record with little distraction from the operative field, so that he may readily follow the stimulation responses or progress of the patient. 4. 4. The ideal system would include a second camera unit. This would provide the electroencephalographer with a detailed view of the operative field. 5. 5. The mobility of the unit and its adaptability provides controlled electrocorticography without the need of special construction or expensive structural alterations in an operating theatre.

Functional Circuits Through Acoustic Devices

In essence, the communication specialist in the field with his complex electronic gear and the native who beats a hollow log both perform the same function-communication over a distance. However, there is no gainsaying that the hollow log is undoubtedly the more reliable of the two communication equipments. The implication of this analogy is not as far fetched as it may appear. It has been found that considerable circuit simplification with a consequent increased reliability are attainable through the application to electronic circuits of the mechanical and acoustic properties of certain materials. Miniaturized, rugged, low cost, highly selective band-pass filters ranging from 100 cps to approximately 10 Mc are feasible. Power transformers without core or coil are definite possibilities. Stable delay media provide large delays in small simple packages. Hybrid structures of conventional parts and nonconventional resonators provide techniques for broadbanding and impedance transformation. A new element, it is expected, will soon be generated for use at low frequencies-a passive four-terminal nonreciprocal network.

Two Uses of Probability Paper in Scintillation Gamma-Ray Spectroscopy

Probability paper can greatly facilitate scintillation gamma spectroscopy because plots of reliable peaks on such paper, as percentage of toal counts vs. pulse height, show straight lines can be used (1) to measure the internal consistency of the performance of the spectrometer electronic gear and (2) to determine the photopeak width at half-maximum. The relative slope of the straight line is a measure of the apparent line width or percentage energy resolution of the spectrometer. An example of this method is given in which the Cs137 gamma spectrum as recorded by an NaI crystal is analyzed.

Special power and lighting systems on aircraft carriers

SINCE the introduction of aircraft carriers to the Fleet of the U. S. Navy their role has continually increased in scope as well as in importance. This has been due chiefly to advances made in aircraft and associated weapons and systems. These advances have had a direct effect on the electric power requirements of the ship service and emergency power system. Fig. 1 shows how ship service generating plants have continually grown, the CV4 in 1930 to the CVA(N) at the present time. The generating capacity of the CVA(N) is ten times greater than that of the CV4. Although this increased power demand has been necessitated by a number of factors such as higher ship's speeds, larger hulls, and more electronic gear, this discussion will cover only certain special power and lighting systems which are considered to be broad enough in scope to be treated individually.

Estimate of the Generation of Fluctuating Surface Pressures on Hypersonic Vehicles

The fluctuating surface-pressure coefficient, i.e., the ratio of root-mean-square pressure at the surface to local dynamic pressure outside the boundary layer, has been shown to be approximately equal to the usual skin friction coefficient. Extremely large fluctuating pressures will be encountered on many missiles and manned aircraft by virtue of the extremely large dynamic pressures associated with high velocities. The integrity of electronic and associated gear may well be jeopardized by such high levels. This paper provides a means of estimating the probable minimum fluctuating surface pressures which will be experienced and indicates the nature of the frequencies which would be expected by virtue of high forward velocity.

Parts vs. systems: The reliability dilemma

One branch of the Service found that it had spent some fifteen times the original cost on certain electronic gear. The total cost of military equipment to the Services must include the cost of spares, maintenance and repair, plus the changes found necessary after the equipment has been accepted for use. When you add to this the problem of getting and keeping competent technicians, the growing emphasis on reliability is not hard to understand.

Transients in Mechanical Systems

A study of the response of an electrical network or system to the input of transients in the form of short-duration pulses is an accepted method of analysis of the network. By comparing the input and the output, conclusions may be drawn as to the respective merit of the various components. Until recently similar procedures were only of academic interest with mechanical systems. However, the tests for mechanical ruggedness, which are required of electronic gear in order to pass specifications for the armed forces, are an example of the application of transients to a mechanical system. These tests are known as High Impact Shock Tests.
