Mapping Dilution of Precision (MDOP) and map-matched GPS
International Journal of Geographical Information Science, 2002A novel method of map matching using the Global Positioning System (GPS) has been developed which uses digital mapping and height data to augment point position computation. This method reduces the error in position, which is a sum from several sources, including signal delay due to the ionosphere and atmosphere and until recently from ‘selective ...

Correcting refractive dilution of precision in wireless network geolocation estimates
2012 6th International Conference on Signal Processing and Communication Systems, 2012Obtaining precise geolocation estimates for mobile devices requires knowledge of the local propagation velocity of light. Under common atmospheric conditions, incorrect propagation velocity estimates introduce systemic dilution of precision using time difference of arrival techniques.

An automatic photometric method with high precision by gradually diluting a sample
Talanta, 1997An automatic photometric method to increase the precision of measurement is proposed, which is based on the injection of a very small volume of sample by rotary valve and the subsequent homogeneous mixing in a small reaction cell made of glass of the sample with a color-developing reagent gradually delivered by a syringe piston pump until the ...

Analytical solutions for passive source positioning and Geometric Dilution of Precision
2015 IEEE International Conference on Information and Automation, 2015This paper provides a closed form analytical solution for TDOA three dimensional (3D) acoustic source localization with four synchronized ultrasonic generators or receivers. Then a pure analytical solution for Geometric Dilution of Precision (GDOP) with four signal generators or receivers is derived instead of a least square solution. The proposed GDOP

Aroma Extract Dilution Analysis. Precision and Optimal Experimental Design
Journal of Agricultural and Food Chemistry, 2002The odor thresholds of 12 different compounds have been determined in an AEDA experiment using a panel composed of 8 individuals. Only in one case is the distribution of thresholds among judges significantly different from the log-normal. The cause of that departure from normality seems to be a cross adaptation rather than anosmia.

Estimating the precision of serial dilutions and viable bacterial counts
International Journal of Food Microbiology, 2002The propagation of error in serial dilutions was investigated theoretically and by means of computer simulations. The principal aim of the study was, given only the pipette manufacturer's specification, to estimate the variance of any step in a dilution series both of pure solutions and of homogeneous bacterial suspensions by means of simple formulae ...

Geometric dilution of precision in Global Positioning System navigation
Journal of Guidance and Control, 1981The evaluation of the GPS navigation performance is essentially equivalent to the computation of the diagonal terms of the geometric dilution of precision (GDOP) matrix. Certain theoretical results concerning the general properties of the GDOP matrix are obtained.
