The final grade is determined using the final score applying the following limits: 85% FS A (excellent) 72% FS < 85% B (good) 65% FS < 72% C (satisfactory) 50% FS < 65% D (pass) FS < 50% F (fail) b) in examination period. none c) Disciplinary Measures Against the Application of Unauthorized Means at Mid-Terms, Term- End Exams and Homework Supplement to 1/2013. (I. 30.) Dean s Order (Codicil): The following students are subject to disciplinary measures. (a) Those students who apply unauthorized means (book, lecture notes, etc.), different from those listed in the course requirements and/or adopted by the lecturer in charge of the course assessment, in the written mid-term exams taken, and/or invite/accept any assistance of fellow students, with the exception of borrowing authorized means, will be disqualified from taking further mid-term exams in the very semester as a consequence of their action. Further to this, all of their results gained in the very semester will be void, can get no term-end signatures, and will have no access to Late Submission option. Final term-end results in courses with practical mark will automatically become Fail (1), the ones with exam requirements will be labelled Refused Admission to Exams.

3 (b) Those students whose homework verifiably proves to be of foreign extraction, or alternatively, evident results or work of a third party, are referred to as their own, will be disqualified from taking further assessment sessions in the very semester as a consequence of their action. Further to this, all of their results gained in the very semester will be void, can get no term-end signatures, and will have no access to Late Submission options. Final term-end results in courses with practical mark will automatically become Fail (1), ones with exam requirements will be labelled Refused Admission to Exams. (c) Those students who apply unauthorized means (books, lecture notes, etc.), different from those listed in the course requirements and/or adopted by the lecturer in charge of the course assessment, in the written term-end exams taken, and/or invite/accept any assistance of fellow students, with the exception of borrowing authorized means, will immediately be disqualified from taking the term-end exam any further as a consequence of their action, and will be inhibited with an automatic Fail (1) in the exam. No further options to sit for the same exam can be accessed in the very same exam period. (d) Those students who alter, or make an attempt to alter the already corrected, evaluated, and distributed test or exercise/problem, i.) as a consequence of their action, will be disqualified from further assessments in the respective semester. Further to this, all of their results gained in the very semester will be void, can get no term-end signatures, and will have no access to Late Submission options. Final termend results in courses with practical mark will automatically become Fail (1), the ones with exam requirements will be labelled Refused Admission to Exams; ii.) and will immediately be inhibited with an automatic Fail (1) in the exam. No further options to sit for the same exam can be accessed in the very same exam period. 10. Retake and repeat There is a retake for both tests in the examination period. Late submission of the homework is possible applying the general rules. 11. Consulting opportunities: Consultation hours: the general consultation hours of the lecturer are posted at energia.bme.hu at the beginning of each semester. 12. Reference literature (compulsory, recommended): Books recommended: - Maglic, K. D., Cezairliyan, A., Petelsky, V. E.: Compendium of Thermophysical Property Measurement Methods, Vol. 1, Plenum Press, New York, Özisik, M. N.: Finite Difference Methods in Heat Transfer, CRC Press, Downloadable materials: energia.bme.hu/~czel or ftp://ftp.energia.bme.hu/pub/ 13. Home study required to pass the subject: Contact hours 42 h/semester Home study for the courses 14 h/semester Home study for the mid-semester checks 12 h/check Preparation of mid-semester homework 10 h/homework Home study of the allotted written notes - h/semester Home study for the exam - h/semester Totally: =30 3credits h/semester 14.
