A network is said to have Sense of Direction when the port labeling satisses a particular set of global consistency constraints. In this paper we study the link between the topology of a system and the number of labels that are necessary to have a Sense of Direction in that system. We consider systems whose topology is a regular graph and we study the relationship between structural properties ...

We consider matching functions in vector quantization (VQ) based speaker recognition systems. In VQ-based systems, a speaker model consists of a small collection of representative vectors, and matching is performed by computing a dissimilarity value between the unknown speaker’s feature vectors and the speaker models. Typically, the average/total quantization error is used as the dissimilarity ...

We prove the equivalence among symmetricity, time reversibility, and zero entropy production of the stationary solutions of linear stochastic differential equations. A sufficient and necessary reversibility condition expressed in terms of the coefficients of the equations is given. The existence of a linear stationary irreversible process is established. Concerning reversibility, we show that t...

The use of groups in combinatorics goes long ways back, and group related constructions are often among the most beautiful constructions known; a claim amply demonstrated in Spyros Magliveras’ work. While this is clearly due to the high level of symmetry of the resulting structures, the usefulness of groups in combinatorics goes beyond this obvious explanation, and group based constructions oft...

This paper proposes a novel translation-based knowledge graph embedding that preserves the logical properties of relations such as transitivity and symmetricity. The embedding space generated by existing translation-based embeddings do not represent transitive and symmetric relations precisely, because they ignore the role of entities in triples. Thus, we introduce a role-specific projection wh...

A drawing concerns the process of generating geometric representations relational information, usually for visualization purposes. good provides an understanding system to reader, while a poor may create confusion. lot information related graphs and graph drawings can be stored using data structures where vertices represent entities edges correspond relationships among entities. In this paper, ...

In this paper, artificial synapses based on four terminal ferroelectric Schottky barrier field effect transistors (FE-SBFETs) are experimentally demonstrated. The polarization switching dynamics gradually modulate the barriers, thus programming device conductance by applying negative or postive pulses to imitate excitation and inhibition behaviors of biological synapse. excitatory post-synaptic...

Wind loads for the design of wind-resistant high-rise buildings are generally evaluated based on spectral modal analysis or time-history response using wind pressure data obtained from tunnel experiments with rigid models. The characteristics fluctuating pressures around vibrating must be relevant designs because affected by their vibrations. One methods to investigate fields is complex proper ...
