Validation of HDOP Measure for Impact Detection in Sensor Network-Based Structural Health Monitoring

IEEE Sensors Journal, 2009
This paper studies the validity of horizontal dilution of precision (HDOP) measure to evaluate sensor network geometries when localizing impacts in structural health monitoring (SHM). First, HDOP is defined similarly to navigation applications. Even though several low-complexity closed-form solutions have been proposed recently, HDOP measure has been ...

Different kinases desensitize the human δ-opioid receptor (hDOP-R) in the neuroblastoma cell line SK-N-BE upon peptidic and alkaloid agonists

Cellular Signalling, 2008
In a previous work, we described a differential desensitization of the human delta-opioid receptor (hDOP-R) by etorphine (a non-selective and alkaloid agonist) and delta-selective and peptidic agonists (DPDPE ([D-Pen(2,5)]enkephalin) and deltorphin I (Tyr-D-Ala-Phe-Asp-Val-Val-Gly-NH(2))) in the neuroblastoma cell line SK-N-BE (Allouche et al., Eur. J.

The Distributions of HDOP and VDOP in GNSS and a Corresponding New Algorithm of Fast Selecting Satellites

Lecture Notes in Electrical Engineering, 2012
In Global Navigation Satellite System (GNSS), the accuracy of position estimates depends upon the measurement geometry and pseudorange measurement errors. The Dilution of Precision (DOP) provides a simple characterization of the user-satellite geometry.

Robust Positioning Algorithm for a Yard Transporter Using GPS Signals with a Modified FDI and HDOP

International Journal of Precision Engineering and Manufacturing, 2018
This paper proposes a robust positioning algorithm using a modified fault detection and isolation (FDI) algorithm and the horizontal dilution of precision (HDOP) for localising a yard transporter using the global positioning system (GPS). In conventional approaches, each GPS signal received is analysed to determine if it is contaminated and only the ...

Distribution of carrier-free90Y(III) between solutions of sodium nitrate, nitric acid and dioctyl phosphate (HDOP) in cyclohexane

Journal of Radioanalytical Chemistry, 1976
Carrier-free90Y isotope was used to study the distribution between the aqueous solution of nitric acid and sodium nitrate and HDOP in cyclohexane. The distribution coefficients (D) were measured as a function of the acidity and the nitrate concentration (MNO 3) in the aqueous phase. The acid dependence was studied in a HNO3 concentration range of 1–14M.
