Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Circular, Vol. 107: January 12, 1909 This species was introduced into the United States some time prior to 1879, in which year, on the authority of Mr. Jacob Doll, a living moth was captured in a spider's web at Hoboken, N. J In 1884 Dr. E. B. Southwick, then entomologist of the public parks of New York City, recognized the destructive Work of this species in Central Park. In 1887 it was seen at Newark, N. J but was not actually recorded as occurring in this country until the following year. In 1890 the junior author observed the moths at electric lights at Orange, N. J. Fortunately the spread of this insect, particularly in the immediate vicinity of New York City, has been very slow, a fact which may be attributed to several causes, (1) the slowness of the flight of the female, (2) the dominance of sparrows in large cities, causing our native birds, such as woodpeckers, to be driven to the country, where they destroy the moths, and (3) the bowl-shaped electric-light globes, hollow at the top and closed at the bottom, which were formerly in general use in our large cities. The males are strongly attracted to brilliant lights and many were captured and perished in these globes in earlier years. Other cities in New Jersey' where this species has been troublesome are Elizabeth, Irvington, Montclair, Arlington, Asbury Park, Ocean Grove, and New Brunswick. Mr. H. M. Russell of this Bureau collected specimens at Bridgeport, Conn, in 1901. The species is now an inhabitant also of Staten Island and has spread on Long Island well beyond the confines of greater New York. South ward it was reported a pest, in 1901, at Ocean Grove, N. J and by 1905 it was recorded by Felt as occurring at Kensico, N. Y., 25 miles north of New York City. By 1907 it was captured at New Haven, Conn, by Prof. H. W. Foote. It is now stated to be injurious in the vicinity of Boston, Mass. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Available in PDF, EPUB and Kindle. Book excerpt: Despite their variety, the vibration phenomena from many different engineering fields can be classified into a relatively few basic excitation mechanisms. The classification enables engineers to identify all possible sources of excitation in a given system and to assess potential dangers. This graduate-level text presents a synthesis of research results and practical experience from disparate fields in the form of engineering guidelines. It is particularly geared toward assessing the possible sources of excitation in a flow system, in identifying the actual danger spots, and in finding appropriate remedial measures or cures. Flow-induced vibrations are presented in terms of their basic elements: body oscillators, fluid oscillators, and sources of excitation. By stressing these basic elements, the authors provide a basis for the transfer of knowledge from one system to another, as well as from one engineering field to another. In this manner, well-known theories on cylinders in cross-flow or well-executed solutions from the field of wind engineering--to name just two examples--may be useful in other systems or fields on which information is scarce. The unified approach is broad enough to permit treatment of the major excitation mechanism, yet simple enough to be of practical use.
