Minimizing losses at interfaces

Science, 2017
Solar Cells Among the issues facing the practical use of hybrid organohalide lead perovskite solar cells is the loss of charge carriers at interfaces. Hou et al. show that tantalum-doped tungsten oxide forms almost ohmic contacts with inexpensive conjugated polymer multilayers to create a hole-transporting material with a small interface barrier.

Loss minimization in DC drives

IEEE Transactions on Industrial Electronics, 1991
A method for determining the optimal DC machine excitation for loss minimization is presented. The proposed method may be implemented by using either analog or digital techniques. The method is simple, and its implementation does not affect significantly the cost, the complexity, and the dynamics of the DC drive.

Children with Minimal Hearing Loss

Intervention in School and Clinic, 2002
Children with minimal hearing loss are often not identified, and the educational implications of their hearing disability are unrealized. Because children with special learning problems have been shown to have a higher incidence of hearing loss than typical learners (Flexer, Millin, & Brown, 1990), special educators should be particularly aware of

CONSTRAINED MULTIVARIATE LOSS FUNCTION MINIMIZATION

Quality Engineering, 2001
Modifying Taguchi's one-dimensional quadratic loss function to a multidimensional form has attracted many researchers because a more accurate estimate of total loss due to variation from multiple quality targets would result. This article includes a..

Minimizing Load-dependent Gear Losses

Tribologie und Schmierungstechnik, 2019
Im Rahmen der vorliegenden Untersuchung wurden mehrere Optimierungsmasnahmen zur Reduktion der lastabhangigen Verzahnungsverluste schrittweise auf den 6. Gang eines Pkw-Handschaltgetriebes angewendet. Im Einzelnen wurden die Einflusse der Zahnradgeometrie, der Zahnflankenoberflache, des Einlaufvorgangs, des Schmieroltyps sowie des Olstandes untersucht.

Loss minimization in synchronous motors

Proceedings of the IEEE International Symposium on Industrial Electronics, 2002
It is known that if an electrical machine does not operate at nominal load, nominal magnetic flux is not required. This means that if magnetic flux is reduced, iron losses can be reduced also. On the contrary, copper losses at the stator are increased for a given constant load.

Loss Minimization Based Keyword Distillation

2004
Keywords provide rich semantic information for documents. It benefits many applications such as topic retrieval, document clustering, etc. However, there still exist a large amount documents without keywords. Manually assigning keywords to existing documents is very laborious. Therefore it is highly desirable to automate the process.

Minimization of Power Losses in Cooperating Manipulators

1991 American Control Conference, 1991
The control of multiple manipulators handling a common object entails the solution of an underdetermined system of linear equations which represents the system’s dynamics. In order to choose an optimal solution to this problem, various approaches have been proposed: minimum internal force and minimum power, among others.

Loss-framed minimal intervention increases mammography use

Women's Health Issues, 2005
Although mammography is the most effective early detection breast cancer screening technology available, it is underutilized. This study was conducted to test the effectiveness of a loss-framed minimal intervention to increase mammography use. Loss-frame refers to a communication strategy in which messages are framed from the perspective of what a ...
