Left Ventricular Long Axis Dynamics in Pathological and Physiological Left Ventricular Hypertrophy
… measured using tissue Doppler echocardiography (TDE). During systole the annulus descends and during early diastole (E<sub>TDE</sub>) and atrial systole (A<sub>TDE</sub>) it ascends. This thesis examined whether changes in the velocity of the annulus in each of these phases of oscillation, …

Time Delay Estimate Based Direction of Arrival Estimation for Speech in Reverberant Environments
Time delay estimation (TDE)-based algorithms for estimation of direction of arrival (DOA) have been most popular for use with speech signals. This is due to their simplicity and low computational requirements. Though other algorithms, like the steered response power with phase transform (SRP-PHAT), …

Localization of Dynamic Acoustic Sources with a Maneuverable Array
… is accomplished via time delay estimation (TDE). Conventional TDE methods, such as the generalized cross-correlation (GCC) method, make the assumption of a direct-path signal model and thus suffer localization performance loss in shallow water, multipath environments. Correlated multipath …

Echo Delay Estimation to Aid Source Localization in Noisy Environments
Time-delay estimation (TDE) finds application in a variety of problems, be it locating fractures or steering cameras towards the speaker in a multi-participant conference application. Underwater acoustic OFDM source localization is another important application of TDE. Existing underwater acoustic …

A hybrid-structure offset-QAM filter-bank multi-carrier MIMO system
… a zero-forcing (ZF) time domain equalization (TDE) is exploited to further reduce the computational complexity with comparable performance bit-error-rate (BER). On the other hand, to tackle the high PAPR problem of the OQAM/FBMC system in the uplink, a novel single carrier (SC)-OQAM/FBMC MIMO …

Comparison of edge turbulence velocity analysis techniques using Gas Puff Imaging data on Alcator C-Mod
… present. We have found that the tracking TDE analysis weights low frequency, low wavenumber features most heavily since they are typically the most intense, but systematically returns a smaller velocity than expected due to issues associated with averaging. After adjusting for these …

Fracaso renal agudo en niños críticos: epidemiología y factores pronósticos
… Se emplearon técnicas de depuración extrarrenal (TDE) en el 60 % de los casos. Las modalidades más frecuentes fueron la diálisis peritoneal y la hemofiltración o hemodiafiltración veno-venosa continua con cifras superiores al 40 % para ambas. Los pacientes con TDE tenían con mayor frecuencia una …

Phase Transform Time Delay Estimation to Counteract Spectral Haystacking Effects in Jet Exhaust Flow Measurements
… more challenging, with an observed 22% anomalous TDE selection rate for the N1Corr = 60% and N1Corr = 70% conditions combined, versus only 6% for the idle and N1Corr = 50% conditions combined. This paper also details the development and first use of a novel acoustic source that produces a two-tone …

Low-Complexity Iterative Receiver Design for Multi-Carrier Faster-Than-Nyquist Signaling Over Frequency-Selective Fading Channel
… Numerical results verify that the VAMP-TDE algorithm is superior in terms of BER performance, while the VAMP-FDE algorithm is able to compromise between BER performance and computational complexity.

IoT Networking via Cross-technology Communication
… contribution is a time-domain signal emulation (TDE) approach which allows a LTE transmitter to produce emulated ZigBee or Bluetooth signal by approximating their time-domain waveform. In addition, it addresses other practical constraints (e.g., turbo coding constraint) to achieve transparent CTC …
