Resumen
ABSTRACT Objective To determine the usefulness of uterine artery Doppler in evaluation of third trimester high-risk pregnancies in prediction of adverse perinatal outcome. Methods In this prospective study uterine artery Doppler parameters such as PI and early diastolic notch were recorded in a group of 60 high-risk pregnancies mainly consisting of pre-eclampsia and small for gestational age. Uterine artery score (UAS) was calculated from the Doppler parameters and a score ≥ 2 was considered abnormal. Perinatal outcome was then correlated to this score and compared with umbilical artery Dopple

Resumen
Not any radar dwell time of a drone radar is suitable for detecting micro-Doppler (or jet engine modulation, JEM) produced by the rotating blades in radar signals of drones. Theoretically, any X-band drone radar system should detect micro-Doppler of blades because of the micro-Doppler effect and partial resonance effect. Yet, we analyzed radar data detected by three radar systems with different radar dwell times but similar frequency and velocity resolution, including Radar−α, Radar−β, and Radar−γ with radar dwell times of 2.7 ms, 20 ms, and 89 ms, respectively. The results indicate that Radar

Resumen
Shift-frequency jamming is generally used to form range false targets for ground-based early-warning radar systems; the frequency shift value of such interference is larger than the Doppler shift value of the moving target, and the key element to suppress the shift-frequency jamming is the frequency shift value estimation. However, in the low- or medium-pulse repetition frequency (PRF) mode, it is challenging to estimate the accurate frequency shift due to the velocity ambiguity. To solve this problem, a novel sparse Doppler-sensitive waveform is designed based on the ambiguity function theory

Resumen
ABSTRACT This review aims to provide the reader with an update on the present and potential clinical applications in Doppler ultrasound in perinatal medicine. Umbilical artery Doppler plays an important role in the management of intrauterine growth restriction (IUGR) and pre-eclampsia and aids in twin-to-twin transfusion syndrome management while notching in the waveform is a predictor of umbilical cord abnormalities. Middle cerebral artery Doppler reliably detects fetal anemia and may be useful in the assessment of IUGR as well. Abnormal uterine artery Doppler may play a role in predicting gr

Background: Scrotal issues often prompt patients to seek evaluation through physical examinations and scrotal ultrasonography. Accurate diagnosis requires a comprehensive exploration of potential conditions, with both grayscale ultrasonography (USG) and duplex Color Doppler ultrasonography employed for assessment.

Resumen
INTRODUCTION: Placental growth factor (PlGF) is involved in placental angiogenesis and maturation. Low maternal serum PlGF levels predict placental dysfunction and associated conditions, such as preeclampsia, and fetal growth restriction. These pregnancy complications can lead to abnormal fetal Doppler assessment, indicating progressive fetal deterioration prompting preterm delivery. METHODS: We collected retrospective data from laboratory results of PlGF levels and fetal Dopplers (umbilical artery [UA], middle cerebral artery [MCA], and ductus venosus [DV]) from patients who had clinical indi

International Telemetering Conference Proceedings / October 30-November 02, 1989 / Town & Country Hotel & Convention Center, San Diego, California<br>At the present time there is a requirement for developing an airborne approach for processing radar doppler video data into digital PCM format compatible with current IRIG standards. Techniques for digitizing the doppler video presently exist, but have limitations due to the fact that the data is processed and represented in the time domain.

Resumen
Laser Doppler flowmetry (LDF) is virtually the only non-invasive technique, except for other laser speckle based techniques, that enables estimation of the microcirculatory blood flow. The technique was introduced into the field of biomedical engineering in the 1970s, and a rapid evolvement followed during the 1980s with fiber based systems and improved signal analysis. The first imaging systems were presented in the beginning of the 1990s. Conventional LDF, although unique in many aspects and elegant as a method, is accompanied by a number of limitations that may have reduced the clinical imp

Nel corso del secolo XIX il fisico James Clerk Maxwell riassunse le leggi sull'elettromagnetismo nelle note equazioni che portano il suo nome, dalle quali è stato possibile estrapolare la natura ondulatoria della luce. Questa importantissima caratteristica, per la quale la luce è definita come onda elettromagnetica, implica una grande vastità di fenomeni di origine ondulatoria, tra i quali l'Effetto Doppler, il quale ha importantissime applicazioni nell'ambito astrofisico e cosmologico.

Resumen
L’effetto doppler fu scoperto dall'austriaco Christian Johann Doppler che nel 1842 fece una pubblicazione, affermando che un oggetto luminoso deve cambiare colore se posto in moto rispetto ad un osservatore. Infatti notò, sfruttando un vagone con alcuni musicisti sopra, come il suono variasse in base al moto relativo tra vagone ed osservatore. Un'analisi più dettagliata mostrò che un ascoltatore in moto verso una sorgente sonora ferma rispetto al mezzo di trasmissione, riceve un suono di frequenza maggiore rispetto a quello che ascolterebbe se anche lui fosse a riposo. Viceversa la frequenza è

Viene trattato l'effetto Doppler nell'ambito classico, analizzando in che modo variano le caratteristiche di un'onda quando la sua sorgente e l'osservatore che la rileva si muovono uno rispetto all'altro. Una breve appendice tratterà,poi, dello stesso effetto nel regime relativistico. In seguito, si analizza come l'effetto Doppler venga utilizzato per determinare la massa delle stelle componenti un sistema binario spettroscopico, e come lo si utilizzi come scala di distanza cosmica sfruttando il così detto Redshift Cosmologico.

Resumen
Abstract Peripheral artery disease (PAD) results from atherosclerotic plaque deposition on arterial walls causing reduced blood flow to affected tissue and can result in pain, tissue loss, poor wound healing, limb loss, and death. Diagnosis of PAD and clinical assessment of these patients requires the use of a vascular Doppler device. By emitting an ultrasound signal when placed over an artery and measuring the Doppler shift of the signal reflected from moving blood cells, this device produces an audio output descriptive of several blood flow parameters.
