Efficiencies and Work Losses for Cycles Interacting with Reservoirs of Apparent Negative Temperatures [PDF]

Entropy, 2019
Inverted quantum states of apparent negative temperature store the work required for their creation [Struchtrup. Phys. Rev. Lett. 2018, 120, 250602]. Thermodynamic cycles operating between a classical reservoir and an inverted state reservoir seem to ...

Reducing Apparent Losses Caused By Meters Inaccuracies

Water Practice and Technology, 2006
Apparent losses caused by meters inaccuracies can be reduced by analysing meters performance in the water supply and identifying the main causes of inaccuracies. These can have its origin on the meters design and accuracy curves, users’ consumption patterns, or specific characteristics of the water supply system.

Methodology for the Identification of Apparent Losses in Water Distribution Networks

Procedia Engineering, 2014
AbstractIn a distribution water network, only a small part represents an economical input for the operator organisms and in some cities it has been estimated big losses in the network, according to the International Water Association (IWA). In water distribution network system most of them results of leaks which are presented in storage tanks, and home

Taking water efficiency to the next level: digital tools to reduce non-revenue water

Journal of Hydroinformatics, 2021
Efficiency optimization of urban water systems is a growing concern for water utilities worldwide. This case study aimed at evaluating the impact of using cloud-based tools on the reduction of both real (real-time network monitoring) and apparent water ...

Determination of Value and Location of the Leakage in Water Distribution Networks Using Calibration (Case Study: The Water Distribution Network of Golbahar, Khorasan Razavi) [PDF]

آب و فاضلاب, 2020
Nan-revenue water (NRW) is one of the most important problems in water distribution networks (WDN). A different method is presented for detection and reduction of NRW. In this paper demands is calibrated using ant colony optimization (ACO).

The apparent loss of PRC2 chromatin occupancy as an artefact of RNA depletion

Cell Reports, 2023
Abstract RNA has been implicated in the recruitment of chromatin modifiers, and previous studies have provided evidence in favour and against this idea. RNase treatment of chromatin is a prevalent tool for the study of RNA-mediated regulation of chromatin modifiers, but the limitations of this approach remain unclear.

Apparent coherence loss in phase space tomography [PDF]

Journal of the Optical Society of America A, 2017
A sensor pixel integrates optical intensity across its extent, and we explore the role that this integration plays in phase space tomography. The literature is inconsistent in its treatment of this integration-some approaches model this integration explicitly, some approaches are ambiguous about whether this integration is taken into account, and still

CONTRIBUTION TO THE STUDY OF MEASURES FOR THE REDUCTION OF APPARENT WATER LOSS IN URBAN AREAS [PDF]

Ambiente & Sociedade, 2016
In Brazil, the average revenue losses of water utilities is around 36%. This value, resulting from high water losses, warns of the need for improvement in the efficiency of service providers, especially as regards the share of apparent losses which can ...

Evaluation of losses in electrical subtransmission networks by neural network modeling

Dyna, 2022
Determining technical losses in an electrical systems is highly complex due to the large amount of information required for its evaluation. One solution to this problem is the evaluation of losses using an artificial neural network.
