Pragmatics of fraus: Encoding and Decoding of Deceit in Seneca’s Troades and Thyestes
2020
The paper aims at exploring the most relevant strategies of encoding and decoding of fraus and simulatio in Seneca’s tragedies, especially in Troades and Thyestes, from both a pragmatic and a dramaturgical point of view. In this perspective, it also provides a working definition of fraus, having regard to the Roman cultural categories involved in the communication dynamics portrayed by Seneca.
Modeling Multi-label Recurrence in Data Streams
2019
Most of the existing data stream algorithms assume a single label as the target variable. However, in many applications, each observation is assigned to several labels with latent dependencies among them, which their target function may change over time. Classification of such non-stationary multi-label streaming data with the consideration of dependencies among labels and potential drifts is a challenging task. The few existing studies mostly cope with drifts implicitly, and all learn models on the original label space, which requires a lot of time and memory. None of them consider recurrent drifts in multi-label streams and particularly drifts and recurrences visible in a latent label spa…
Super-resolved or field of view enlarged imaging based upon spatial depolarization of light
2010
Abstract In this paper we present a new approach allowing the surpassing of the diffraction based limitation for the achievable resolution provided by imaging systems. It is based on an encoding–decoding process of various spatial pixels or regions in the field of view of the imaged object by orthogonal and differently time varying polarization states. The reconstruction of the original spatial information is obtained by applying a decoding process in a way similar to the encoding one. Although all the spatial information is summed and mixed together by the system, the decoding provides super-resolved imaging since in every spatial position the undesired spatial information having time vary…
Speech-input multi-target machine translation
2007
In order to simultaneously translate speech into multiple languages an extension of stochastic finite-state transducers is proposed. In this approach the speech translation model consists of a single network where acoustic models (in the input) and the multilingual model (in the output) are embedded. The multi-target model has been evaluated in a practical situation, and the results have been compared with those obtained using several mono-target models. Experimental results show that the multi-target one requires less amount of memory. In addition, a single decoding is enough to get the speech translated into multiple languages.
Identifying musical pieces from fMRI data using encoding and decoding models.
2018
AbstractEncoding models can reveal and decode neural representations in the visual and semantic domains. However, a thorough understanding of how distributed information in auditory cortices and temporal evolution of music contribute to model performance is still lacking in the musical domain. We measured fMRI responses during naturalistic music listening and constructed a two-stage approach that first mapped musical features in auditory cortices and then decoded novel musical pieces. We then probed the influence of stimuli duration (number of time points) and spatial extent (number of voxels) on decoding accuracy. Our approach revealed a linear increase in accuracy with duration and a poin…
Diagonal space time hadamard codes with erasure decoding algorithm
2005
A major challenge in the area of space time (ST) codes is to find codes suitable for efficient decoding, thus overcoming the problem of many existing ST code designs which require maximum-likelihood (ML) decoding. A solution could be to apply single-input single-output (SISO) channel codes and theory over temporal channel fading to the multi-input single-output (MISO) code construction and classical suboptimum decoding methods. For these purposes, an ST code construction which allows the use of efficient decoding algorithms is described. We propose a concatenated code, where the inner code is the diagonal ST Hadamard (D-STH) code with Paley constructions and the outer code is an algebraic b…

Reading comprehension in French 1st and 2nd grade children: Contribution of decoding and language comprehension
2006
This paper reports a study conducted with French first-grade and second-grade children (mean age: 6;8 and 7;8 respectively). The first aim was to re-examine the Gough and Tunmer’s (1986) Simple View in assessing the specific contribution of decoding ability and language comprehension to reading comprehension. The second one was to analyse the difficulties of children in reading comprehension. Reading and listening comprehension were assessed using both visual and auditory version of the same test. Decoding ability was assessed by means of a nonword reading test. On the basis of reading comprehension scores, skilled and less skilled comprehenders were contrasted, and then two groups of less …
Secrecy analysis and learning-based optimization of cooperative NOMA SWIPT systems
2019
Non-orthogonal multiple access (NOMA) is considered to be one of the best candidates for future networks due to its ability to serve multiple users using the same resource block. Although early studies have focused on transmission reliability and energy efficiency, recent works are considering cooperation among the nodes. The cooperative NOMA techniques allow the user with a better channel (near user) to act as a relay between the source and the user experiencing poor channel (far user). This paper considers the link security aspect of energy harvesting cooperative NOMA users. In particular, the near user applies the decode-and-forward (DF) protocol for relaying the message of the source no…
Decoding the XXI Century’s Marketing Shift: An Agency Theory Framework
2016
Since the beginning of the XXI century, marketing theory has moved through a series of epistemological shifts from modern positivism to postmodern constructivism. This has resulted in a series of changes to the main concepts of “traditional” marketing such as: market, product, customer, and value. These shifts can be better viewed under a social cybernetics approach such as agency theory. This is because there is now a view that the linear concept of value creation needs to give way to the more complex process of value cocreation, where value is created collectively. Agency theory is one approach that is able to shed light on how customers and providers are able to recursively create collec…
