Special Issue Information

Dear Colleagues,

Bioinspiration, understood as the use of biological processes for inspiration in engineering and computational designs, has become a widespread approach for both the engineer and the computational scientist to study, model, and resolve complex issues. Technological advances, such as the increasing affordability of high-performance computational resources, extensive, fast, and accessible storage capacities, high-speed communication networks, along with a growing and vibrant international practitioner community, make the field an attractive opportunity to develop innovative solutions to the increasingly complex and uncertain issues humanity is facing today, which are impossible to face by means of classical or analytical paradigms.

Furthermore, it has also been recognized that bioinspired approaches stimulate synergy among scientific disciplines. Multi- and transdisciplinary work have become essential for the advancement of this area. Researchers from different knowledge fields can contribute toward unified goals, sharing their perspectives through discussion, interaction, and collaboration, which leads to bioinspired knowledge discovery and dissemination. Such processes enrich scientists’ respective areas of interest and open new possibilities for their studies.

It is with this horizon in mind that we have launched this Special Issue. Published works are expected to be the result of multi- and transdisciplinary efforts, which present innovative findings beyond each expert’s specific knowledge area. We look forward to contributions that not only propose new bioinspired engineering and computational methods and solutions, but are exemplary of an effective and rewarding collaboration between colleagues from diverse areas that will continue to contribute to the growth of the field.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Computation is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease that affects the nerve cells in the brain and spinal cord. This condition leads to the loss of motor skills and, in many cases, the inability to speak. Decoding spoken words from electroencephalography (EEG) signals emerges as an essential tool to enhance the quality of life for these patients. This study compares two classification techniques: (1) the extraction of spectral power features across various frequency bands combined with support vector machines (PSD + SVM) and (2) EEGNet, a convolutional neural network specifically designed for EEG-based brain–computer interfaces. An EEG dataset was acquired from 32 electrodes in 28 healthy participants pronouncing five words in Spanish. Average accuracy rates of 91.04 ± 5.82% for Attention vs. Pronunciation, 73.91 ± 10.04% for Short words vs. Long words, 81.23 ± 10.47% for Word vs. Word, and 54.87 ± 14.51% in the multiclass scenario (All words) were achieved. EEGNet outperformed the PSD + SVM method in three of the four classification scenarios. These findings demonstrate the potential of EEGNet for decoding words from EEG signals, laying the groundwork for future research in ALS patients using non-invasive methods. Full article
