Analysis of single event transients in arbitrary waveforms using statistical window analysis
Window functions are commonly used in data processing to detect transient events or for time-averaging of frequency spectra. A generalized window function is demonstrated using the Ionizing Radiation Effects Spectroscopy (IRES) technique to enhance the measurement of transient anomalies within …

ΣΧΕΔΙΑΣΗ ΟΙΚΟΝΟΜΙΚΩΝ F.I.R. ΦΙΛΤΡΩΝ ΓΙΑ ΣΗΜΑΤΑ ΔΙΑΜΟΡΦΩΣΗΣ Δ
… A SPECIAL MODIFICATION IN THE APPLICATION OF THE WINDOW METHOD. CLEARLY THE WINDOW FUNCTION IS ADJUSTED IN EACH FILTER IN SUCH A WAY THAT MOST OF ITS COEFFICIENTS ARE SIMPLY RELATED TO EACH OTHER. IT IS SHOWN THAT THIS SIMPLE RELATIONSHIP AMONG MOST OF THE FILTER COEFFICIENTS ACTUALLY 1 : 2, …

Gabor frames with trigonometric spline dual windows
… of modulated and translated copies of a window function. If we have a signal in $L^2(\mathbb{R})$, it can be analyzed with a Gabor system generated by a certain window $g$ and then synthesized with a Gabor system generated by another window $h$. If this leads us to a perfect …

A New Machine Learning Algorithm for Detection of Stray Clays
… stray clay signal strength from GPR data. A new window function in neural networks SmoothGrad which helps to filter the most of the anomalies effects on clay seam number 414 is utilized. This window length which tries to smooth GPR signal by supressing the noise, can be measured by adding the …

Mixed-Signal Architectures for Spectrum Sensing
… capacitive loads that implements current-domain windowing in the first stage while downconversion mixing and integration is implemented in the second stage. A load capacitor array enables integration with programmable time constant. A prototype was designed and fabricated in IBM's 0.13Âľm CMOS …

Dissipative Matsubara Dynamics
… the harmonic oscillator and a linear correlation function cropped with a window function. In this work, we present results for up to 200 Matsubara modes and fully converged non-linear correlation functions. This was achieved by developing dissipative Matsubara dynamics — a way of implicitly …

ΚΑΘΟΡΙΣΜΟΣ ΤΗΣ ΔΙΑΝΟΜΗΣ ΤΩΝ ΠΕΔΙΑΚΩΝ ΜΕΓΕΘΩΝ ΣΕ ΣΥΣΤΗΜΑ ΑΓΩΓΙΜΩΝ ΠΛΑΚΩΝ ΑΠΟ ΔΙΕΓΕΡΣΗ ΓΕΝΙΚΕΥΜΕΝΗΣ ΜΟΡΦΗΣ ΜΕ ΕΦΑΡΜΟΓΗ ΤΟΥ ΑΛΓΟΡΙΘΜΟΥ FFT
… THE INVERSE DISCRETE FOURIER TRANSFORM (IDFT) OF FUNCTIONS THAT ARE NOT DURATION LIMITED AND NOT BAND LIMITED IS CONSIDERED. FOR THIS CATEGORY OF FUNCTIONS TWO KINDS OF ERRORS ARE INTRODUCED, BY THE USE OF DFT OR IDFT. THESE ERRORS ARE THE TRUNCATION ERROR (TE)AND THE ALIASING ERROR (AE). THESE …

Harmonic analysis in power network with renewable power generator
… with frequencies different from that of the window function frequency. In order to overcome the limitations of Fourier analysis and obtain better results, wavelet analysis has been proposed. A novel harmonic analysis method using Discrete Wavelet Packet Transform (DWPT) filter bank …

Easy-filter: A Design, Verification, and Validation Tool for Finite Impulse Response (FIR) Filter
… for the short time-to-market requirement, functional verification becomes the primary challenge in the hardware design development project. The essential parts to verify any systems are design code and testbench code. However, it is very labor-intensive to write these codes and prone to …

Software-defined pulse-doppler radar signal processing on graphics processors
… and constant false-alarm rate (CFAR) processing functions were then implemented and optimized for the GPU architecture. Multiple algorithmic variants were implemented, where appropriate, to evaluate the efficiency of different algorithmic structures on the GPU architecture. These functions were …

The data processing to detect correlated movement of Cerebral Palsy patient in early phase
… with the formation of time-dependent transfer functions and the coherence property is the key to the diagnostic approach. Combinations of each limb's movement and their relationship can represent the correlated movement. Data collected from a normal baby is used to develop the technique for …
