International Scientific Conference on Engineering, Technologies and Systems TechSys
Over the years, the TechSys conference has been recognized as a leader in forums dedicated to technical science and engineering. It has become a dedicated space for meetings between leading researchers, young scientists, and representatives of leading companies in the industry. The primary goal of TechSys is to bring together individuals from academia and industry, scientists, and experts in engineering and technology to share their ideas and innovations.
The conference program includes the following thematic sessions:
- Automation, Control Systems and Robotics;
- Electrical Engineering and Electronics;
- Computer Engineering, Informatics and Communications;
- Mechanical Engineering;
- Automotive and Aeronautical Engineering;
- Materials Science.
The TechSys Organizing and Program Committee strives to ensure maximum compliance with modern publication standards as well as dissemination of published papers to the entire international academic community.
Dear Colleagues,
On behalf of the Organizing Committee and the International Programme Committee, we would like kindly to invite you to participate in the 15th International Scientific Conference on Engineering, Technology and Systems – TechSys 2026.
The conference will be held in Plovdiv, Bulgaria at the Technical University of Sofia, Plovdiv Branch between 14 and 16 May 2026.
We are striving to respond to the utmost degree to the contemporary requirements for publication of papers, as well as to enhance the possibility that the presented papers be shared across the international academic community.
Paper publishing:
There are two different options for paper publishing and respectively an independent selection process for both of them will proceed:
- Option 1: The selected papers are going to be published Open Access in Engineering Proceedings by MDPI indexed by a number of leading databases, including Scopus
- Option 2: The selected papers are going to be published in the volume 31 of Journal of the Technical University – Sofia, Plovdiv, Branch “Fundamental Sciences and Applications”, ISSN 2603-459X
Note that:
!!! Authors are encouraged to use the Microsoft Word template or LaTeX template to prepare their manuscript.
Please consider following instructions when you are preparing your manuscript for TECHSYS 2026:
- Microsoft Word: Manuscripts prepared in Microsoft Word must be converted into a single file before submission. When preparing manuscripts in Microsoft Word, we encourage you to use the Microsoft Word template file. Please insert your graphics (schemes, figures, etc.) in the main text after the paragraph of its first citation.
- LaTeX: Manuscripts prepared in LaTeX must be collated into one ZIP folder (including all source files and images, so that the Editorial Office can recompile the submitted PDF). When preparing manuscripts in LaTeX, we encourage you to use the LaTeX template files. You can now also use the online application writeLaTeX to submit articles directly to Engineering Proceedings. The MDPI LaTeX template file should be selected from the writeLaTeX template gallery.
- For detailed information please see Manuscript Preparation TECHSYS 2026.pdf
- Manuscript submission: Please upload your submission in both file formats – PDF and DOC (LaTeX).
!!! Two papers per author (co-author) in each publishing option are allowed.
!!! All papers have to be written in English.
