Effects of DME Pilot Quantity on the Performance of a DME PCCI-DI Engine

Energy Conversion and Management, 2010
Abstract The combination of premixed charge compression ignition and conventional direct-injection compression ignition combustion is studied in a DME engine. This combustion mode is referred to as PCCI-DI combustion. The pilot quantity is found to be one of main variables affecting the PCCI-DI combustion. So, the main objectives of this paper are to

DME, vous avez dit DME ?

Spirale, 2023
La diversification alimentaire est un sujet qui préoccupe beaucoup les nouveaux parents. Quand commencer ? Quels aliments proposer ? En quelles quantités ? En purée ou en morceaux ? À toutes ces questions, les manuels de puériculture et les professionnels de santé ont des réponses qui, par leur précision minutieuse, engendrent plus d’inquiétude que de ...

DME/DME position and velocity estimation

2018 26th Signal Processing and Communications Applications Conference (SIU), 2018
As an alternative to Global Positioning System (GPS) position calculation can be achieved using Distance Measuring Equipments (DME). DME calculates and outputs a slant range using the total time from the aircraft interrogation to ground station reply. It is necessary to have two DMEs to calculate the position from the slant range data.

Optimal strategy of DME beacon distrbution for DME/DME area navigation

2012 IEEE 11th International Conference on Signal Processing, 2012
Distance measuring equipment (DME) is important ground based navigation system for implementation of area navigation (RNAV), and its positioning accuracy is directly related to geometric dilution of precision (GDOP). For the distribution of three DME beacons, this paper establishes the GDOP algorithm model based on DME/DME RNAV, the GDOP calculation is

Dimethyl ether (DME)

Toxicology and Industrial Health, 2022
The WEEL guide for dimethyl ether (DME) was originally established in 1996 and updated in 2010. Literature searches to identify new toxicity information were performed in November 2020 and evaluated by the WEEL Revisions Subcommittee. No new studies or data relevant to the WEEL guide were identified.

DME Multipath Simulations as a Critical enabler to Support DME/DME RNP Reversion

The International Technical Meeting of the The Institute of Navigation, 2019
DME has become the main alternative (A-PNT) system to GNSS in the short/mid term, but most aircraft avionics do not include On Board Performance Monitoring and Alerting (OPMA) for DME, limiting the use of DME/DME for RNAV applications and not RNP ones.

Ignition Control by DME-Reformed Gas in HCCI Combustion of DME

SAE Technical Paper Series, 2003
<div class="htmlview paragraph">Homogeneous charge compression ignition (HCCI) combustion enables higher thermal efficiency and lower NOx emission to be achieved in internal combustion engines compared with conventional combustion systems. Adjusting the proportion oftwo fuels with different ignition properties is an effective technique for ...

Molecular structure of ThBr4(DME)2 (DME = 1,2-dimethoxyethane)

Journal of Chemical Crystallography, 1999
The molecular structure of ThBr4(DME)2 (DME = 1,2-dimethoxyethane), the first structurally characterized thorium complex containing a simple bidentate ether ligand, is described. The eight-coordinate complex presents a distorted dodecahedral geometry, with Th—Br and Th—O bond lengths in the ranges 2.8516(13)–2.8712(13) A and 2.564(8)–2.620(8) A ...
