Intrasystem Transmission Losses
Transactions of the American Institute of Electrical Engineers, 1943THIS paper describes a new method of calculating transmission losses within power systems. Reasonable accuracy is obtained with longhand calculation, although the same general scheme with the load-flow determinations carried out on a d-c calculating board would provide greater accuracy with less work.

The measurement of sound transmission loss of panels with small transmission loss
Journal of Sound and Vibration, 1965Abstract The transmission room method for the measurement of transmission loss is reviewed and the lower limits of validity established. An alternative method for measuring low loss panels is described.

Baseflow and transmission loss: A review
Wiley Interdisciplinary Reviews: Water, 2021AbstractThere is an extensive literature dealing with the interaction between groundwater and surface water, and this includes major reviews on baseflow, transmission losses, baseflow recession analysis, and broader aspects of low flows. Although these are mature topics in hydrology, they continue to attract strong interest, with hundreds of papers ...

Transmission and coupling losses in a folded waveguide
Applied Optics, 1989This paper discusses the transmission and coupling losses of hollow dielectric waveguide modes in a folded waveguide structure. The folded structure consists of two square-bore waveguides placed symmetrically above a spherical mirror with a nonzero on-axis angle between them. The presence of the fold renders the structure astigmatic.

Quantum theory of laser transmission loss
Physical Review A, 1989A semiclassical treatment of the radiation loss in a laser, previously investigated by Baseia and Nussenzveig (Opt. Acta 31, 39 (1984)), is extended to the quantum-theory level. The model employs an optical cavity having an output coupling that includes the radiation loss due to the beam extraction through appropriate boundary conditions, instead of ...

Proceedings of the Institution of Mechanical Engineers, 1963
Transmission losses are determined for 20 wire ropes commonly used in crane and hoist practice. The apparatus and procedure used in determining the losses are described and the results are presented in the form of graphs. From these graphs the law governing the losses is established.

OTLR:Opportunistic Transmission with Loss Recovery for WLANs
2008 IEEE Wireless Communications and Networking Conference, 2008With opportunistic transmissions, a node exploits a stable high data rate to transmit multiple frames (instead of one) whenever it captures a contended medium. The IEEE 802.11 networks could support such multi-frame transmissions at high data rates if the channel remains stable long enough.

Transmission loss in an alberich tile
Ferroelectrics, 1996Abstract Elastromeric tiles have been developed as effective reflectors of hull- born acoustic energy. To aid designers theoretical models have been developed to predict performance. Here we present a scheme based upon the finite element method which considers the tile as being composed of an infinite doubly periodic plane with fluid above and below ...
