AN EXAMPLE OF CRANIOPLASTY WITH THE ASSISTANCE OF 3D PRINTING TECHNOLOGY: A CASE REPORT
Cranioplasty is the surgical repair of a bone defect in the skull that is left behind after a severe injury or previous operation. It is usually done to protect underlying brain tissue, reduce local pain and to improve the cranial vault aesthetics. Cranial prostheses can be made from different types of materials: autologous bone, titanium, ceramics...

INFLUENCE OF CONTRACTION SHAPE ON THE FLOW QUALITY IN WIND TUNNEL TEST SECTION
Contraction is a part of a wind tunnel that has the greatest impact on the air flow quality in the test section. The constriction ratio, the cross section shape, the length and wall shape are constructive parameters that influence the uniformity of the flow, the flow turbulence intensity, the flow rotation angularity, the appearance of the flow sep...

CALCULATION INDEX OF RELIABILITY ON THE EXAMPLE OF THE SHED OF A STEEL HALL, COMPARATION OF PTP AND EC-1 REGULATIONS FOR SNOW LOAD
This paper deals with the resistance of the shed of a steel hall in Drvar according to technical regulations for snow from 1961 and EC1 regulations. The paper aims to check the reliability of the shed with probabilistic approach. That also implies calibration of the steel hall construction analyzed with classic deterministic method. Statical system...
