The Trends in Computational and Applied Mathematics (TEMA) is a new Journal sponsored by the Brazilian Society for Computational and Applied Mathematics (SBMAC). The SBMAC was established in 1978 as a scientific organization to develop and promote Computational and Applied Mathematics among its communities in Brazil. Currently the SBMAC has over 300 members and annually organizes the National Congress of Computational and Applied Mathematics.
In 1999 the SBMAC has created the TEMA journal. It has published 21 volumes since then and became a leading journal in the field. The increase of manuscripts submissions written in English language, in the past few years, from both Brazilian and foreigner researchers alike, indicate that the journal TEMA achieved an international profile.
The new journal, Trends in Computational and Applied Mathematics, marks the rebirth of TEMA as a truly international journal, yet one that preserves its history and the high profile that it has achieved. Our goals are to publish original research, theoretical developments and application studies on promising themes; to offer an interdisciplinary and reliable international forum; to provide an efficient peer-review system, leading to a fast response time.

Author Guidelines:

a) About author responsibility over the manuscript contents
The authors take full responsibility for the contents in research papers (manuscripts) submitted to Trends in Computational and Applied Mathematics. Although all information published in this journal are considered true and accurate, the editors and the publisher cannot be held legally responsible for any possible mistakes or omissions. The publisher offers no warranty of any kind, explicit or implicit, of the published contents.

b) Information about keywords or descriptors
In the first page of the manuscript, the author should write, according to Trends in Computational and Applied Mathematics journal standards, a title, names, complete corresponding addresses (including e-mail and address), and an abstract written in English with three keywords.

c) About references and bibliography
Trends in Computational and Applied Mathematics uses IEEE-TR standard style that present the references according to the citation order and has a standard abbreviation author’s name. Bibliography references should be performed with bibtex package, following the instructions provided in the template.

d) Language

e) About author rights transfer
Presenting a manuscript implies that: the described work has not been published yet (except as an abstract or thesis); that the work is not being considered for publication in another journal and that the manuscript has been approved by all authors. The copyright remains with the authors.

f) Peer review process
Analysis and approval of manuscripts submitted to Trends in Applied and Computational Mathematics - starts with the on-line submission of the manuscript. Afterwards, the Editor-in-Chief assign the manuscript to suitable Associate Editor, which is responsible in choosing suitable ad-hoc reviewers in corresponding research areas. Reviewers receive the full manuscript, without access to the identity of the authors through the system, which ensures a blind review process. Each manuscript is evaluated by two ad-hoc reviewers at least.
The Journal does not adopt the open peer review policy.
Trends in Computational and Applied Mathematics recommends to keep the research data available in open access repositories.

g) Authorship
If and when the paper is accepted and the final version sent, it is implicitly that all the authors contributed ted as even as possible in the article research, writing and final version. Other collaboration forms are not considered as authorship by the Journal.

The analisys and evaluation of manuscripts starts with the on-line submission of the manuscript. Afterwards, the Editor-in-Chief assign the manuscript to suitable Associate Editor, which is responsible in choosing suitable ad-hoc reviewers in corresponding research areas. The evaluation is performed by at least two ad hoc reviewers who have no access to the identity of the authors through the system, which ensures a blind review process. Therefore, manuscripts should be submitted in ".pdf" format, without author identification.

Research related to humans and animals should include the official letter of approval from the ethics committee.
The Journal follows the standards in the Guidelines on Best Practices
from SciELO:

https://wp.scielo.org/wp-content/uploads/Guide-to-Best-Practices-for-Strengthening-Ethics-in-Scientific-Publishing.pdf

Among others practices we highlight:

• In order to guarantee text originality the Journal uses the software Turnitin which checks duplicity among previously published texts.
• When in the evaluation process, editors or reviewers identify excess self-citing by authors and/or the journal, all authors are contacted for clarification to support decision making.
• The fabrication or falsification of data and images are serious cases of misconduct. The evaluation process should be judicious in identifying such misconducts. In case there are any doubts, the authors are requested to provide supporting evidence of the methodology and results. In case of proven misconduct, the editor should inform the authors’ affiliation institutions or funding agencies involved in the development of the research.
• The already published article in which misconduct is identified remains indexed in the SciELO database in the retracted condition. The retraction substantiate the reason for the withdrawal duly referenced, through a communication by the author, editor or another authorized agent, and published in the same journal. Retraction may be partial when the misconduct applies to a specific part of the article, without, however, compromising the set of published research. The article may not ever be “unpublished”. Cases of errors or failures, regardless of nature or origin, that do not constitute misconduct, are corrected by errata.
• The journal publishes as promptly as possible errata, corrections or retractions.

If conflicts between evaluative positions (by authors and reviewers) arises, the article may be sent to other evaluators and/or members of the Editorial Commission. The final decision on any conflicts and on the publication of the text is given by the Editor, Adjunct Editor and a representative indicated by SBMAC who will take into account the combined evaluative process and the code of conduct for editorial norms.

Trends in Computational and Applied Mathemathics is guided by the "Guidelines on Best Practices from SciELO":
