Some of Turnbull's recordings of Efé music were commercially released, and inspired more ethnomusicological study, such as by Simha Arom, a French-Israeli who recorded a kind of whistle called hindewhu, and by Luis Devin, an Italian ethnomusicologist who studied in depth the musical rituals and instruments of Baka Pygmies, also by taking part in their secret rite of initiation.

Some Great Western " autocoaches "— from where the driver operated the steam engine's regulator and brakes, when the engine was propelling one or more autocoaches — still had a whistle connection with the engine's brake whistle, although a gong ( much like a tram gong ) was fitted at the front of each autocoach and was operated by the driver using a foot treadle.

Some people even like the sound of the whistle, as it calls to mind a nostalgic era, as with the riverboats and their steam whistles and calliopes.

Some were composed of three whistle chimes.

Some whistle designers minimized this problem by building resonant chambers of a similar scale.

Some people love to crack tile and it's amazing what beautiful designs they come up with as a result of their cracking good time.

Some popular designs use the following types of ANOVA:

Some were little more than stopgap solutions, mounting an anti-tank gun on a tracked vehicle to give mobility, while others were more sophisticated designs.

Some smaller designs have been used as the basis for specialist fighters, such as night fighters, and a number of fighters, such as the Hawker Hurricane were used as ground attack aircraft bombers, replacing earlier conventional light bombers that proved unable to defend themselves and carry a reasonable bombload.

Some water clock designs were developed independently and some knowledge was transferred through the spread of trade.

Some designs had no explicit spring as such ; it was simply a compliant mechanism.

Some CPU designs compile the instruction set to a writable RAM or FLASH inside the CPU ( such as the Rekursiv processor and the Imsys Cjip ), or an FPGA ( reconfigurable computing ).

Some efficient designs for estimating several main effects simultaneously were found by Raj Chandra Bose and K. Kishen in 1940 at the Indian Statistical Institute, but remained little known until the Plackett-Burman designs were published in Biometrika in 1946.

Some important contributors to the field of experimental designs are C. S. Peirce, R. A. Fisher, F. Yates, C. R. Rao, R. C. Bose, J. N. Srivastava, Shrikhande S. S., D. Raghavarao, W. G. Cochran, O. Kempthorne, W. T. Federer, V. V. Fedorov, A. S. Hedayat, J.

Some aficionados who prefer class-A amplifiers also prefer the use of thermionic valve ( or " tube ") designs instead of transistors, especially in Single-ended triode output configurations for several claimed reasons:

Some of Cheney's motorcycle designs are now famous in their own right, such as the competition BSA Gold Stars of Jerry Scott and Keith Hickman and the John Banks replica which used a BSA B50 engine specially tuned by Cheney.

Some complex flag designs are not intended for through and through implementation, requiring separate obverse and reverse sides if made correctly.

* Some stained glass designs by Ford Madox Brown

Some older or high-end instruments have inlays made of mother of pearl, abalone, ivory, colored wood or other exotic materials and designs.

Some combination or hybrid bits combine direct pressure and leverage, such as the Kimblewick or Kimberwicke, which adds slight leverage to a two-rein design that resembles a snaffle ; and the four rein designs such as the single mouthpiece Pelham bit and the double bridle, which places a curb and a snaffle bit simultaneously in the horse's mouth.

Some later ram designs in the UK called compound rams were designed to pump treated water using an untreated drive water source, which overcomes some of the problems of having drinking water sourced from an open stream.

Some modern and experimental comb designs are complex in the way that they direct the air.

Some former Soviet scientists said they were actually hampered by Fuchs's data, because Beria insisted that their first bomb (" Joe 1 ") should resemble the American plutonium bomb (" Fat Man ") as much as possible, even though the scientists had discovered a number of improvements and different designs for a more efficient weapon.

Some of those designs proved a success, whilst others fared less well when practically tested.

Some designs of these scatterable mines require an electrical charge ( capacitor or battery ) to detonate.

Some well known designs that have this capability include JPEG 2000 for still images and H. 264 / MPEG-4 AVC based Scalable Video Coding for video.

Some small form factor computers and home theater PCs designed for quiet and energy-efficient operation boast fan-less designs.

Some of the latest designs ( such as the German Puma ) are intended to allow a light, basic model vehicle which is air-transportable to be fitted in the field with additional protection, thereby ensuring both strategic flexibility and survivability.

Some designs include general-purpose microprocessor cores, with one or more ROM, RAM, or I / O functions integrated onto the package.
