Enhanced PUMA for direction-of-arrival estimation and its performance analysis

Cheng Qian
Direction-of-arrival (DOA) estimation is a problem of significance in many applications. In practice, due to the occurrence of coherent signals and/or when the number of available snapshots is small, it is a challenge to find DOAs accurately. This problem is revisited here through a new enhanced principal-singular-vector utilization for modal analysis (EPUMA) DOA estimation approach, which improves the threshold performance by first generating ($P+K$) DOA candidates for $K$ sources where $P\geq K$, and then judiciously...

Code for "Revisiting the boron systematics of aragonite and their application to coral calcification"

Thomas DeCarlo
The isotopic and elemental systematics of boron in aragonitic coral skeletons have recently been developed as a proxy for the carbonate chemistry of the coral extracellular calcifying fluid. With knowledge of the boron isotopic fractionation in seawater and the B / Ca partition coefficient (KD) between aragonite and seawater, measurements of coral skeleton δ11B and B / Ca can potentially constrain the full carbonate system. Two sets of abiogenic aragonite precipitation experiments designed to quantify KD have recently made...

Mario A. Quiroz-Juarez, Omar Jimenez-Ramirez, Ruben Vazquez-Medina, Elena Ryzhii, Maxim Ryzhii & Jose L. Aragon
We present the code for an extended heterogeneous oscillator model of cardiac conduction system for generation of realistic 12 lead ECG waveforms. We incorporate an artificial RR-tachogram with the specific statistics of a heart rate, the frequency-domain characteristics of heart rate variability produced by Mayer and respiratory sinus arrhythmia waves, normally distributed additive noise and a baseline wander that couple the respiratory frequency. The standard 12 lead ECG is calculated by means of a weighted...

Parasitic Self and Mutual Inductances of Thin-Film Capacitors

Joaquin Bernal Mendez
Program for calculating parasitic self and mutual inductances of shunt-capacitor filters constructed with one, two or three thin-film capacitor placed in close proximity. Compares performances of several arrangements of thin film capacitors: 1) One capacitor 2) Two capacitors with currents in same direction (parallel) 3) Two capacitors with currents in opposite direction (anti-parallel) 4) Three capacitors with currents in same direction (parallel) 5) Three capacitors with currents in opposite direction (anti-parallel)

Results Analysis: Modeling Non-Uniform Memory Access on Large Compute Nodes with the Cache-Aware Roofline Model

Brice Goglin, Emmanuel Jeannot, Aleksandar Ilic, Leonel Sousa & Nicolas Denoyelle
The Cache-Aware Roofline Model (CARM) is an insightful, yet simple model designed to address this issue. It provides feedback on potential applications bottlenecks and shows how far is the application performance from the achievable hardware upper-bounds. However, it does not encompass NUMA systems and next generation processors with heterogeneous memories. Yet, some application bottlenecks belong to those memory subsystems, and would benefit from the CARM insights. In this paper, we fill the missing requirements to...

Thameur Dhieb, Sourour Njah, Houcine Boubaker, Wael Ouarda, Mounir Ben Ayed & Adel M. Alimi
The presented code consists of the preprocessing and the segmentation of online handwriting into a sequence of Beta strokes in a first step. Then, from each Beta stroke, we extract a set of static and dynamic features using four features extraction techniques based on the Beta-Elliptic model and the Fuzzy Elementary Perceptual Codes. Next, all the segments which are composed of N consecutive Beta strokes are categorized into groups and subgroups according to their position...

A Multivariate Regime-switching GARCH Model

Markus Haas & Ji-Chun Liu
We consider a multivariate Markov-switching GARCH model which allows for regime-specific volatility dynamics, leverage effects, and correlation structures. Conditions for stationarity and expressions for the moments of the process are derived. A Lagrange Multiplier test against misspecification of the within-regime correlation dynamics is proposed, and a simple recursion for multi-step-ahead conditional covariance matrices is deduced. As an application, we model the dynamics of the joint distribution of global stock market and real estate equity returns....

Matrix Completion with Temporal Constraint

Andy J Ma, Jacky CP Chan, Frodo KS Chan, Pong C Yuen, Terry CF Yip, Yee-Kit Tse, Vincent WS Wong & Grace LH Wong
Regular medical records are useful for medical practitioners to analyze and monitor patients health status especially for those with chronic disease. However, such records are usually incomplete due to unpunctuality and absence of patients. In order to resolve the missing data problem over time, tensor-based models have been developed for missing data imputation in recent papers. This approach makes use of the low-rank tensor assumption for highly correlated data in a short-time interval. Nevertheless, when...

Improving Energy Efficiency of Field-Coupled Nanocomputing Circuits by Evolutionary Synthesis

Marco A. Ribeiro, Iago A. Carvalho, Jeferson F. Chaves, Gisele L. Pappa & Omar P. Vilela Neto
Moore's law provoked decades of advances in computer's performance due to transistor's evolution. Despite all success in its improvement, current technology is reaching its physical limits and some replacements are the focus of investigations, such as the Field-Coupled Nanocomputing devices. These devices achieve information transfer and computation via local field interactions, reaching ultra-low power consumption. Nevertheless, there exists a hard energy limit related to the Laws of Thermodynamics that bounds any digital evaluation. To reduce...

Unmixing Signal and Noise for Photon-Efficient Active Imaging

Joshua Rapp
We introduce a new approach to depth and reflectivity estimation that emphasizes the unmixing of contributions from signal and noise sources. At each pixel in an image, short-duration range gates are adaptively determined and applied to remove detections likely to be due to noise. For pixels with too few detections to perform this censoring accurately, data are combined from neighboring pixels to improve depth estimates, where the neighborhood formation is also adaptive to scene content.
