Reconstruction of a heat transfer coefficients by using FWA approach

BibTeX does not have the right entry for preprints. This is a hack for producing the correct reference:

@Booklet{EasyChair:575,
  author = {Zoltán Fried and Sándor Szénási and Imre Felde},
  title = {Reconstruction of a heat transfer coefficients by using FWA approach},
  howpublished = {EasyChair Preprint no. 575},
  doi = {10.29007/l6qh},
  year = {EasyChair, 2018}}
