TL;DR: Single-mode fiber couplers produced as fused biconical-taper structures are reported on that exhibit low loss, arbitrary branching ratio, polarization independence, and broadband operation in wavelength.
Abstract: Single-mode fiber couplers produced as fused biconical-taper structures are reported on. The devices exhibit low loss (0.5 dB), arbitrary branching ratio, polarization independence, and broadband operation in wavelength.

TL;DR: In this paper, the authors present three distinct ways of viewing and interpreting a policy of setting growth targets for monetary aggregates and examine the implications of these three methods when the principal aim of policy is reducing the rate of inflation.
Abstract: In the mid-1970s the Bank of Canada, along with a number of other central banks, began to set explicit targets for monetary growth and to emphasize the long-run role of monetary aggregates in controlling the rapid upward trend of prices. There are three distinct ways of viewing and interpreting a policy of setting growth targets for monetary aggregates. The first is associated with the work of William Poole, the second is derived from the reduced-form model initially developed at the Federal Reserve Bank of St. Louis, and the third, which the author has labeled the feedback- rule approach, is related to the techniques developed within central banks to implement the policy of monetary targeting. In this paper the author sets forth the logic and examines the implications of these three methods when the principal aim of policy is reducing the rate of inflation. He also examines the question of gradualist versus "cold-shower" policies and the criteria for selecting a monetary aggregate as a policy target.

TL;DR: In this article, the implications of using the monetary base or bank reserves as an instrument to control a monetary aggregate were analyzed and concluded that in a system with either institutional or structural lags base control may entail very sharp and possibly undamped oscillations of short-term interest rates.
Abstract: This paper focuses on the implications of using the monetary base or bank reserves as an instrument to control a monetary aggregate. Following analysis of a series of theoretical models of increasing complexity, it is concluded that in a system with either institutional or structural lags base control may entail very sharp and possibly undamped oscillations of short-term interest rates. The shorter the time period over which the authorities choose to bring the monetary aggregate back to its target, the more volatile will be the movements of interest rates. Furthermore, there is an asymmetry in the U.S. institutional structure such that rigid implementation of the base control system will under certain circumstances lead to a decline in short-term interest rates to very low levels. The final section of the paper is devoted to the examination of the Canadian institutional structure emphasizing the differences between the U.S. and Canadian systems.

TL;DR: The paper describes how satellite systems are being developed in Canada under these new Regulations and how the 12-GHz band will be used in Region 2.
Abstract: WARC-79 made significant changes to how the 12-GHz band will be used in Region 2. In particular, it decided that the 12-GHz band in Region 2 will extend upwards the 12.7 GHz, and that the upper portion of the overall band (11.7 to 12.7 GHz), will be planned at the 1983 Regional Conference. The paper describes these allocation changes and how satellite systems are being developed in Canada under these new Regulations.

TL;DR: In this paper, the authors discuss new forms of data communications services from a Canadian perspective, and identify issues associated with the services and the new society they encourage, and conclude that a requirement exists for national planning and coordination mechanisms to assure that appropriate systems are in place to foster the orderly introduction, diffusion, and utilization of new data communications.

TL;DR: The rate of technological change made possible by new developments in computers and telecommunications presents the manager with the challenge of managing information technology rather than being managed by information technology.

TL;DR: WISP/HF is a flexible Shuttle/Spacelab instrument for transmitting, receiving and processing signals in the 0.3 to 30 MHz range as discussed by the authors, which is used to study the transmitting antenna, fundamentals of electromagnetic (EM) and electrostatic (ES) waves in magnetoplasmas, plasma instabilities and nonlinearities, and sounding of ionospheric structure.

TL;DR: In this article, the authors present experimental confirmation of Cook's method of calculating the quasi-peak voltage from the Amplitude Probability Distributions (APD) to within ± 2 dB.
Abstract: Based upon a sample of 125 distributions of impulsive power-line noise taken near an HVDC converter station, this paper presents experimental confirmation of Cook's method of calculating the quasi-peak voltage from the Amplitude Probability Distributions. The calculated values compare with measured values to within ± 2 dB. Values for the ratio of quasi-peak to rms voltage levels were found to be 12 dB ± 2 dB for these types of power-line noise.
