Dissertations

Check also the sub pages in my respective page in Greek.

Provisional Dissertations, those marked with a (*) may lead to a paper publication; those marked with (**) will be supervised by Prof. M.J. Anagnostakis and I will provide technical assistance. Implementation of experimental and some theoretical research depends upon subject maturity and equipment, software and funding availability. Part of the mentioned software is not readily available but it can be certainly obtained within reasonable time.

Please note:

(a) Experimental dissertations require a regular physical presence in the Lab. On the other hand, theoretical and/or computational dissertations may be completed remotely.

(b) For graduates that have completed their Dissertation in Nuclear Engineering or even elsewhere, and find themselves in the time gap "in between" successive steps of their career, the subjects leading to a possible paper publication are open for processing for a duration from three to six months. It has to be mentioned: (1) Offers for collaboration will proceed depending mostly on my availability for supervision, (2) There is no obligation for submitting a Thesis-like report for this processing, and (3) Typically, funding possibilities for such work cannot be considered. If the quality of the results is of the publication level, final paper text will be coauthored by the graduate(s) and myself.

(c) Appropriate projects from within the list below are available for students of the 8th spring semester, who wish to register for the elective course "Computational Project". I will be available for the supervision of one student per semester only. Most of the subjects leading to a possible paper publication are open for processing within this course. It has to be mentioned: (1) Students inquiries for a project will be considered depending mostly on my availability for supervision, (2) There is an obligation for submitting a project report , (3) There is an obligation for giving a project results presentation in front of an open audience, and (4) It is not meant by default that a dissertation position will be available for a student completing such a project . If the quality of the project results is of the publication level, final paper text will be coauthored by the student(s) and myself.
