Automatically verifying safety properties of programs is hard. Many approaches exist for verifying programs operating on Boolean and integer values (e.g. abstract interpretation, counterexampleguided abstraction refinement using interpolants), but transposing them to array properties has been fraught with difficulties. Our work addresses that issue with a powerful and flexible abstraction that ...

Frequency domain properties of an image are used for precise detection of edge orientation in color and multi-spectral imagery. The orientation estimation is established as a minimization problem, formulated as a tensor method, and simplified by solving its dual in terms of spatial partial derivatives of the image. First, spectral density distribution around each pixel is obtained. The edge ori...

WE STUDY THE DISCRIMINATION OF EMOTIONS ANNOTATED IN FREE TEXTS AT THE SENTENCE LEVEL: a sentence can either be associated with no emotion (neutral) or multiple labels of emotion. The proposed system relies on three characteristics. We implement an early fusion of grams of increasing orders transposing an approach successfully employed in the related task of opinion mining. We apply a filtering...

We present a practical and elegant method for generating all (s, t)-combinations (binary strings with s zeros and t ones): Identify the shortest prefix ending in 010 or 011 (or the entire string if no such prefix exists), and rotate it by one position to the right. This iterative rule gives an order to (s, t)-combinations that is circular and genlex. Moreover, the rotated portion of the string ...

Hypercube algorithms are developed for a variety of communication-intensive tasks such as transposing a matrix, histogramming, one node sending a (long) message to another, broadcasting a message from one node to all others, each node broadcasting a message to all others, and nodes exchanging messages via a fixed permutation. The algorithm for exchanging via a fixed permutation can be viewed as...

The singing synthesis system we present generates a performance of an artificial singer out of the musical score and the phonetic transcription of a song using a frame-based frequency domain technique. This performance mimics the real singing of a singer that has been previously recorded, analyzed and stored in a database. To synthesize such performance the systems concatenates a set of element...

We construct a 2D holographic ionic lattice with hyperscaling-violating infrared geometry and study single-electron spectral functions (“ARPES photoemission curves”) on this background. The spectra typically show three-peak structure, where the central peak undergoes crossover from sharp but not Fermi-liquid-like quasiparticle to wide incoherent maximum, broad side peaks resemble Hubbard bands....

Modeling consists in aggregating separate pieces of knowledge, according to a given structure and rules. It allows studying the behavior of more or less complex systems by simulation techniques. Modeling is used in different state-of-the-art technological domains (meteorology, aeronautics). Its use has grown for the evaluation of medicines and medical dev...

In this paper, we propose an efficient parallel architecture for the adaptive deblocking filter in H.264/AVC video coding standard. We use six forwarding shift register arrays (of which each contains 4×4 8-bit shift registers) with two transposing operations and two sets of filter operation (each set contains four edge filter operations) to support simultaneous processing of the horizontal and ...

A masked priming lexical decision experiment was conducted to examine whether or not assignment of letter position in a word can be influenced by lexeme boundaries. The experiment was run in Basque, which is a strongly agglutinating language with a high proportion of inflected and compound words. Nonword primes were created by transposing two nonadjacent letters that crossed or did not cross mo...
