Segmented Four-Element Photodiodes in a Three-Dimensional Laser Beam Angle Measurement

open access: yesPhotonics, 2023
Based on the registration of two laser beam projections, a method for measuring the angular deviation of a laser beam from its initial position in three-dimensional space is proposed and experimentally demonstrated.

Are Efficiency Wages Efficient?

open access: yes, 1986
Efficiency wage models have been criticized because worker malfeasance can be prevented in a pareto efficient manner by requiring workers to post a bond which they lose if they are caught cheating. However, since it is costly to monitor workers and costless to demand a larger bond, firms should pay nothing for monitoring and demand very large bonds ...

Efficient Exclusion

open access: yesSSRN Electronic Journal, 2005
In their influential paper, Aghion and Bolton (1987) argue that a buyer and a seller may agree on high liquidation damages in order to extract rents from future suppliers. As this may distort future trade, it may be socially wasteful. We argue that Aghion and Bolton's analysis of entry is incomplete in some respects, as there is only one potential ...

Liberty, Efficiency, and Law [PDF]

open access: yes, 1987
In today’s society there is an increasing demand for renewable energy sources such as sun and wind power. These sources are intermittent, and energy storage is therefore needed to ensure a constant power supply.

The efficiency and eco-efficiency of manufacturing [PDF]

open access: yesInternational Journal of Nanomanufacturing, 2010
In this paper, we review the efficiency of both manufacturing processes and systems over recent decades and compare nano-materials technologies in this context. To a first approximation, nano-materials processes appear to be about as efficient as semi-conductor processes.

Opportunities of energy saving in lighting systems for public buildings

open access: yesRenewable Energy and Sustainable Development, 2017
The lighting system provides many options for cost-effective energy saving with low or no inconvenience. Lighting improvements are excellent investments in most public buildings, it is usually cost-effective to address because lighting improvements are ...

Energy efficiency-spectral efficiency trade-off of transmit antenna selection [PDF]

open access: yes, 2014
We investigate the energy efficiency-spectral efficiency (EE-SE) trade-off of transmit antenna selection/maximum ratio combining (TAS) scheme. A realistic power consumption model (PCM) is considered, and it is shown that using TAS can provide significant

Management of Educational Efficiency and Efficiency [PDF]

open access: yesHOLISTICA – Journal of Business and Public Administration, 2018
Abstract Numerous specialist studies allow managers to find accessible answers on how to develop and increase the autonomy of educational establishments in the type of management model. Every school head has to have a clear vision of the school and of its connection with the society it is part of. The vision of the manager must be shared

Population and species neighbor identity impact trait–trait relationships and plant performance

open access: yesPopulation Ecology, EarlyView.
We evaluated how populations and species identity influence plant performance and trait outcomes in mixtures, and assessed trait variation among populations of two forb species native to the western United States (Dieteria canescens and Heterotheca villosa) following three interaction treatments (single‐population monoculture, two‐population mixture ...
