Broadband Beamforming Using TDL-Form IIR Filters
IEEE Transactions on Signal Processing, 2007Conventional broadband beamforming structures make use of finite-impulse-response (FIR) filters in each channel. Large numbers of coefficients are required to retain the desired signal-to-interference-plus-noise-ratio (SINR) performance as the operating bandwidth increases.

High-resolution TDL-TDC system for MTCA.4 standard
2016 IEEE Nuclear Science Symposium, Medical Imaging Conference and Room-Temperature Semiconductor Detector Workshop (NSS/MIC/RTSD), 2016In this contribution, we present a high-resolution, multi-channel time measuring system (TDC) on an AMC board for MTCA.4 standard. The system allows to measure the inputs with a resolution of less than 25 ps r.m.s. The TDC implemented into the FPGA (Xilinx Virtex5 70T in 67-nm technology, 10000 slices) receives signals from an analog front-end ...

Tumefactive demyelinating lesions (TDLs): A case series of clinicoradiological features
Clinical Neurology and Neurosurgery, 2017Diagnosis of tumefactive demyelination lesions (TDLs) is challenging to neurophysician, neuroradiologist or neurosurgeon. Our objective in this study was to analyze clinicoradiological features of TDLs.A retrospective analysis with prospective follow-up of 11 cases of TDLs was performed.

Classification and representation of types in TDL
2011TDL is a typed feature-based representation language and inference system, specifically designed to support highly lexicalized constraint-based grammar theories. Type definitions in TDL consist of type and feature constraints over the full Boolean connectives together with coreferences, thus making TDL Turing-complete.

TDL-MG v4.0: Theory-Space Has Hyperbolic Geometry
TDL-MG v4.0: Theory-Space Has Hyperbolic Geometry One-Line Summary We discovered that scientific theories naturally embed in hyperbolic space with perfect correlation (r = 1.000) between geometric distance and conceptual complexity—enabling computation of optimal learning paths, complexity prediction, and conceptual navigation.openaire +1 more source
