This paper proposes a novel local feature descriptor, Local Directional Number Pattern (LDN), for face analysis: face and expression recognition. LDN encodes the directional information of the face’s textures (i.e., the texture’s structure) in a compact way, producing a more discriminative code than current methods. We compute the structure of each micro-pattern with the aid of a compass mask, ...

Peace psychology emerged as a distinct area of research and practice during the Cold War, when the preeminent concern was the prevention of nuclear war. Now global in scope, the focal concerns of peace psychologists are nuanced by geohistorical contexts and the distinction between episodic violence and structural violence, the latter of which also kills people, albeit slowly through the depriva...

Chord sequences are an essential source of information in a number of MIR tasks. However, beyond the sequential nature of musical content, relations and dependencies within a music segment can be more efficiently modeled as a graph. Polytopic Graphs have been recently introduced to model music structure so as to account for multiscale relationships between events located at metrically homologou...

We introduce here for the first time the RNAMute package, a pattern-recognition-based utility to performmutational analysis and detect vulnerable spots within an RNA sequence that affect structure. Mutations in these spots may lead to a structural change that directly relates to a change in functionality. Previously, the concept was tried on RNA genetic control elements called “riboswitches” an...

For the natural donor of photosynthetic photosystem II an operational model is postulated. This model combines a definite structural pattern of two types of electron donors (octahedral arrange­ ment of 6 secondary donors around a primary donor) with conformational state dependent electron transfer probability. It is shown that the model provides an explanation of many experimental data, especia...

A recurring question in the study of computer anxiety is whether computer anxiety is a relatively stable personality trait or a mutable, temporary state. The two studies reported examined this question in two groups of first year psychology students. These students were requested to complete a computer anxiety test, a trait anxiety test, and a state anxiety test. Some groups were administered t...

The object of this note is to demonstrate the applicability of the methods of nonlinear functional analysis in the investigation of a complex physical problem. In 1910 T. von Karman [9] introduced a system of 2 fourth order elliptic quasilinear partial differential equations which can be used to describe the large deflections and stresses produced in a thin elastic plate subjected to compressiv...

This paper focuses on the implementation of a novel semantic-based Conversational Agent (CA) framework. Traditional CAs interpret scripts consisting of structural patterns of sentences. User input is matched against such patterns and an associated response is sent as output. This traditional CA approach, which solely takes into account the structural form of a sentence, requires the scripter to...

Given a timed regular expression and a dense-time Boolean signal we compute the set of all matches of the expression in the signal, that is, the set of all segments of the signal that satisfy the regular expression. The set of matches is viewed as a set of points in a two-dimensional space with each point indicating the beginning and end of a matching segment on the real time axis. Our procedur...
