ESWEEK 2021 continues a dual publication model comprising the Journal track and the Work-in-Progress (WiP) track for the three conferences (CASES, CODES+ISSS, and EMSOFT). Journal track papers are full-length papers describing mature work. They will be published in the ACM Transactions on Embedded Computer Systems (TECS). The WiP track papers are short (2-page) papers representing not-yet-mature but promising research. They will be published in the ESWEEK proceedings and will be listed as regular publications within the IEEE and/or ACM digital libraries. Authors of WiP papers have the opportunity to publish an extended form of their work in any conference or journal they prefer. Journal and WiP papers are mutually exclusive, i.e., a work can only be in submission in one of the two tracks. For more information on the ESWEEK dual-track publishing process, ple
