A Tractable Framework for Estimating and Combining Spectral Source Models for Audio Source Separation

The underdetermined blind audio source separation (BSS) problem is often addressed in the time-frequency (TF) domain assuming that each TF point is modeled as an independent random variable with sparse distribution. On the other hand, methods based on stru ...

Probabilistic Model Falsification for Infrastructure Diagnosis

James-Alexandre Goulet

Most infrastructure in the western world was built in the second half of the 20th century. Transportation structures, water distribution networks and energy production systems are now aging and this leads to safety and serviceability issues. In situations ...

Evaluating the singular integrals arising in MPIE formulations with a double-exponential algorithm

Juan Ramon Mosig

Novel generalized Cartesian product rules for the computation of weakly singular integrals, arising in the mixed potential integral equation formulations are presented in this paper. The key feature of the proposed integration schemes lies in the incorpora ...

The Metropolized Partial Importance Sampling MCMC mixes slowly on minimal reversal rearrangement paths

Krister Swenson

Markov chain Monte Carlo has been the standard technique for inferring the posterior distribution of genome rearrangement scenarios under a Bayesian approach. We present here a negative result on the rate of convergence of the generally used Markov chains. ...

Finitary Winning in omega-Regular Games

Games on graphs with omega-regular objectives provide a model for the control and synthesis of reactive systems. Every omega-regular objective can be decomposed into a safety part and a liveness part. The liveness part ensures that something good happens " ...

Interference-Resilient Information Exchange

Rachid Guerraoui, Seth Gilbert

This paper presents an efficient protocol for reliably exchanging information in a single-hop, multi-channel radio network subject to unpredictable interference. We model the interference by an adversary that can simultaneously disrupt up to t of the C ava ...

Critical Sections: Re-Emerging Scalability Concerns for Database Storage Engines

Anastasia Ailamaki, Frederick Ryan Johnson, Ippokratis Pandis

Critical sections in database storage engines impact performance and scalability more as the number of hardware contexts per chip continues to grow exponentially. With enough threads in the system, some critical section will eventually become a bottleneck. ...

Variable latency speculative addition: A new paradigm for arithmetic circuit design

Paolo Ienne, Philip Brisk, Ajay Kumar Verma

Adders are one of the key components in arithmetic circuits. Enhancing their performance can significantly improve the quality of arithmetic designs. This is the reason why the theoretical lower bounds on the delay and area of an adder have been analysed, ...

TCHo: a Hardware-Oriented Trapdoor Cipher

Serge Vaudenay, Willi Meier, Jean-Philippe Aumasson

This paper improves the Finiasz-Vaudenay construction of TCHo, a hardware-oriented public-key cryptosystem, whose security relies in the hardness of finding a low-weight multiple of a given polynomial, and on the decoding of certain noisy cyclic linear cod ...

On capacity of line networks

Christina Fragouli, Daniela Tuninetti, Urs Niesen

We consider communication through a cascade of discrete memoryless channels (DMCs). The source and destination node of this cascade are allowed to use coding schemes of arbi- trary complexity, but the intermediate relay nodes are restricted to process only ...
