Loss reduction in optical fibers
Journal of Non-Crystalline Solids, 1980Abstract 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 ...

European Conference on Cognitive Ergonomics, 2018
Variable flux permanent magnet synchronous machines (VF-PMSMs) have recently been proposed to reduce driving cycle losses in electric vehicle traction motors via magnetization state (MS) manipulation. This paper presents a closed-loop magnetization state

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 ...

Power loss reduction in partially shaded PV arrays by a static SDP technique
Energy, 2018Partial Shading plays a vital role in the power generation from PV arrays. It can drastically reduce the power output from PV arrays resulting in multiple maximum peak points in power-voltage characteristics. The power reduction in PV arrays less depends

An Improved Modulation Scheme of Current-Fed Bidirectional DC–DC Converters For Loss Reduction
IEEE transactions on power electronics, 2018Current-fed bidirectional dc–dc converters have attracted much attention in battery energy storage system applications due to their zero-voltage-switching performances and greater degree of control freedom. However, high efficiency cannot be achieved for

Feeder reconfiguration for loss reduction
2016Distribution networks are generally built as meshed networks, while they are operated radially. Their configurations may be varied with manual or automatic switching operations so that all of the loads are supplied and reduce power loss, increase system security, and enhance power quality.

THE HIGHWAY: OPTIONS FOR LOSS REDUCTION
SAE Technical Paper Series, 1970<div class="htmlview paragraph">Approximately 36% of the deaths and injuries on our highways result from single vehicle accidents. These accidents involve vehicles running off the road, overturning, or striking some fixed object such as bridge piers, retaining walls and abutments, sign posts, lightpoles, trees, guardrails, utility poles, etc ...

Guidance for water loss reduction
2011Le projet de loi Grenelle II s'inscrit dans le prolongement de la loi de programmation relative à la mise en oeuvre du Grenelle de l'environnement, dite "Grenelle I", qui a déterminé les objectifs de l'État dans le domaine environnemental. L’article 58 de ce projet de loi est relatif à l’amélioration des niveaux de pertes en eau sur les réseaux d’eau ...

Reduction of losses at boar cryptorchism
Животноводство РоссииУстановлено, что при доле рождаемости поросят-крипторхидов 0,08% выгоднее произвести их вынужденный убой, при показателе 0,5% и выше эффективно провести кастрацию. Оптимальный возраст кастрации хрячков на изучаемом предприятии — 4–5 месяцев.
