... This data set consists of recordings of original voice and fake voice recordings obtained by imitation [1, 2]. The voice recordings provided in this dataset can be used to train a machine learning system to classify original and fake voice recordings obtained with the imitation algorithm. Each directory has the following composition: Fake_audios: 50 voice recordings of fake audios obtained by imitation Key_fake_audios: 50 keys to reverse the process and obtain the original voice recording Original_audios: 50 original voice recordings readme.txt: this Matlab code allows recovering the original voice recording from the fake voice recording.

... Objective: to produce a mental health podcast with young people from urban poverty contexts , based on their priority, on the processes of individual and social dimensions regarding suicidal behavior. Method: project approved by the applicant institution. Qualitative research developed through action research. The theoretical reference of choice is intersectionality, which reflects the multiplicities of differentiations that, articulating with gender, permeate the social. This approach does not emphasize the determinations of phenomena only on the economic basis, but also from other social markers, since several inequality aspects are now recognized as influencing the subjects' daily practices. The unit selected will be the State School, which belongs to the East Education Board 2, located in the Itaim Paulista neighborhood, east side of São Paulo (SP) - Brazil. Data collection will be performed through workshops - group technique that allows data collection in participatory research. All workshops will be recorded and filmed for further analysis. The instruments and methods of data collection will occur through interviews, field journal and different participatory strategies during the development of the workshops. The interviews will take place according to the questionnaire that apprehends the Social Reproduction Index (SRI), which analyzes the different dimensions of the social life of the groups. It is a tool capable of apprehending the differences of social reproduction that characterize the social classes that are part of a given territory, being able to show the different epidemiological profiles of families, even if they are living in the same micro space. This differentiation enables the planning of educational or other actions. The field journal used to make a dense description of what was observed in the field, written and/or recorded immediately to the field activity. Data processing: the workshops will be transcribed and inserted in the QSRNvivo software, used for text analysis and other materials, such as videos and audios. It is a useful technological tool for qualitative research to organize and analyze data production, which facilitates analysis, since the software is unable to understand the results. Analysis: will be followed a multilevel analysis, which considers the identity construction of the subjects, the symbolic representations and the social structure in which the participants are immersed.

... this source code proposes a dynamic parameterization approach to the ant colony optimization algorithm configuration applied to multi-objective optimization problems. Indeed, the inertia of the static vision of the pheromone or visibility preferences values makes our dynamic approach a desired approach. We propose a model based on a collective knowledge center shared by the colony members, storing the best configurations based on the old experiments of the colony during the learning phase on random problems. The construction of this center is based on a statistical and qualitative study of the evaluation criteria that will be explained over the paper. Our model gives results that show a rise in quality of the outputs, as well as a proof of concept of the artificial learning approach.

... The S-transform (ST) is a popular linear time-frequency (TF) transform with hybrid characteristics from the short-time Fourier transform (STFT) and the wavelet transform. It enables a multi-resolution TF analysis and returns globally referenced local phase information, but its expensive computational requirements often overshadow its other desirable features. In this paper, we develop a fully discrete ST (DST) with a controllable TF sampling scheme based on a filter-bank interpretation. The presented DST splits the analyzed signal into subband channels whose bandwidths increase progressively in a fully controllable manner, providing a frequency resolution that can be varied and made as high as required, which is a desirable property for processing oscillatory signals lacked by previously presented DSTs. Thanks to its flexible sampling scheme, the behavior of the developed transform in the TF domain can be adjusted easily; with specific parameter settings, for example, it samples the TF domain dyadically, while by choosing different settings, it may act as a STFT. The spectral partitioning is performed through asymmetric raised-cosine windows whose collective amplitude is unitary over the signal spectrum to ensure that the transform is easily and exactly invertible. The proposed DST retains all the appealing properties of the original ST, representing a local image of the Fourier transform; it requires low computational complexity and returns a modest number of TF coefficients. To confirm its effectiveness, the developed transform is utilized for different applications using real-world and synthetic signals.
