Impact of correlated observation errors on the convergence of the conjugate gradient algorithm in variational data assimilation
Olivier Goux, Selime Gürol, Anthony T. Weaver +2
An important class of nonlinear weighted least-squares problems arises from the assimilation of observations in atmospheric and ocean models. In variational data assimilation, inve…
MemSE: Fast MSE Prediction for Noisy Memristor-Based DNN Accelerators
Jonathan Kern, Sébastien Henwood, Gonçalo Mordido +4
Memristors enable the computation of matrix-vector multiplications (MVM) in memory and, therefore, show great potential in highly increasing the energy efficiency of deep neural ne…

Vishakha Agrawal, Yong-Han Lin, Jinghui Cheng
Most issue tracking systems for open source software (OSS) development include features for community members to embed visual contents, such as images and videos, to enhance the di…
Characterizing User Behaviors in Open-Source Software User Forums: An Empirical Study
Jazlyn Hellman, Jiahao Chen, Md. Sami Uddin +2
User forums of Open Source Software (OSS) enable end-users to collaboratively discuss problems concerning the OSS applications. Despite decades of research on OSS, we know very lit…
How heated is it? Understanding GitHub locked issues
Isabella Ferreira, Bram Adams, Jinghui Cheng
Although issues of open source software are created to discuss and solve technical problems, conversations can become heated, with discussants getting angry and/or agitated for a v…
On handwriting pressure normalization for interoperability of different acquisition stylus
Marcos Faundez-Zanuy, Olga Brotons-Rufes, Carles Paul-Recarens +1
In this paper, we present a pressure characterization and normalization procedure for online handwritten acquisition. Normalization process has been tested in biometric recognition…
