Optical fiber loss reduction

Electronics and Communications in Japan (Part I: Communications), 1996
AbstractWith the introduction of optical fiber amplifiers, numerous experiments on long‐haul and large‐capacity transmissions at 1.55‐μm band have been done. To realize high‐grade transmission systems, further reduction of optical fiber losses is necessary.In reduction of optical fiber losses, Rayleigh scattering loss, infrared absorption loss, and ...

Loss Reduction in Point Estimation Problems

Economic Quality Control, 2006
Summary: When evaluating point estimators by means of general loss functions, the expected loss is not always minimal, similar to the case of mean-biased estimators, whose mean squared error can be reduced by accounting for the mean-bias. Depending on the loss function, the so-called Lehmann-bias can be significantly more important than the mean-bias ...

Distribution network reconfiguration for loss reduction

2016 International Conference on Electrical, Electronics, and Optimization Techniques (ICEEOT), 2016
This paper discusses the reduction of real power loss in the distribution system by reconfiguration of the distribution network. Reconfiguration is done by changing the status of the sectionalizing and tie switches. The optimal configuration with minimum real power loss is to be determined.

Loss reduction by network switching

IEEE Transactions on Power Systems, 1988
Systematic and fast switching for the purposes of reducing losses in power transmission networks is treated as an optimization problem whereby switching is to be understood in a general and comprehensive way. Injected currents applied to a base network are used to model the switching operation.

Packet Loss Reduction During Rerouting

IEEE Communications Letters, 2011
When a network failure is detected by an IP router, its routing table is updated for all affected routing entries. The packet loss resulting from this event depends on the network traffic associated with the updated routing table entries. In this paper, we model this process, define packet loss minimization heuristics relying on network traffic ...

Power Line Loss Analysis and Loss Reduction Measures

2019
Line damage refers to the power consumption of power grid lines and equipment, an indicator of the power of enterprise self-digestion. The line loss rate is an important technical and economic indicator of the national assessment of power sector energy consumption level; also, the planning and design of power system comprehensively reflect the level of

Reduction of Apparent Water Losses

Proccedings of 10th International Conference "Environmental Engineering", 2017
The water loss levels are very different between European countries as water loss varies from 7% to 50%. According to data from the Lithuanian Water Supply Association, in 2015 about 124 mln. m³ of ground water was supplied to the network, but only 94 mln. m³ of it was sold, while the remaining share represented water losses – 30 mln. m³ per year.

Loss reduction in optical fibers

Journal of Non-Crystalline Solids, 1980
Abstract To reduce the loss of optical fibers to the minimum possible value, the manufacturer must have an accurate estimate of that value together with an understanding of the mechanisms that raise fiber loss above that value. In this paper we separate fiber loss into its absorption and scattering components, present estimates of the minimum ...

REDUCTION OF BLOOD LOSS IN KNEE ARTHROPLASTY

Australian and New Zealand Journal of Surgery, 1984
The purpose of this study was to investigate ways of reducing and controlling blood loss and postoperative anaemia in total condylar knee arthroplasty performed under tourniquet. The study covers a two year period to December 1982. Reduction of blood loss was successfully achieved by being aware of the very rich blood supply to the knee and utilizing ...
