This letter presents a method to find convolutional codes with good translation properties by modifying the generator matrix of existing Codes and using a bit modifier.

We concentrate on those problems that we believe have shown, or will prove, to be useful quantitative paradigms of nonlinear systems.

Against the continuum of the low-frequency ambient sea noise that is due to ships and weather, there appear a variety of 'strange' noises, usually transient in nature.

N a modern communication system the leakance is generally quite small and can be neglected in making propagation computations.

A method has been developed for the measurement of the electrical properties of metal-loaded polystyrene foam artificial dielectrics in the hundred-megacycle frequency range, by the use of a number

T IS an inherent feature of the two-way television system that either user is continuously scanned as he views the image from the distant station.

Some periodic time-varying convolutional codes with free distance greater than the best known time-invariant code of the same rate and total encoder memory are presented.

Prussian blue and other transition metal hexacyanoferrates are known to undergo insertion reactions.

Some Physical Characteristics of Speech and Music * By HARVEY FLETCHER Kinematic and statistical descriptions of the physical aspects of speech and music are given in this paper.
