Preface
The International Congress SMAT 2019 (Science and Management of
AutomotiveandTransportationEngineering)isheldunderthehighpatronageof
Ministry of Education of Romania.
By the collaboration inside SIAR (Society of Automotive Engineers of
Romania), this congress represents the effort of the academic peoples and
researchers from the main Romanian universities centers, Bucharest, Brasov,
Craiova, Cluj-Napoca, Pitesti and Timisoara.
The congress topics are focused on novel, most challenging issues on automo-
tive and transportation, providing both field-related engineers and researchers
within the industry and/or the academic environment the possibility to track down
topical issues disseminated via the congress papers. Public presentation of papers
enables the attendants to initiate and active participate in cross-fertilizing dialogs
that can lead to new interdisciplinary projects and cooperation partnerships.
ThemainpurposeoftheSMAT2019Congressistooffertoallresearchersand
specialistsinautomotivefieldalargediscussionenvironment,aplacetopresentthe
newest achievements in scientific research and innovation activities, within the
topics:
(cid:129) Advanced Powertrain and Propulsion
(cid:129) Road Vehicles and Environment
(cid:129) Modern Transport Systems and Road Traffic
(cid:129) Advanced Engineering Methods
(cid:129) Materials and Technologies.
Thecongressaimstobringtogetheracademics,researchers,engineersandother
specialists from the large field of automotive engineering and road transport, to
foster some of their latest achievements and generate opportunities for further
collaboration. Both plenary sessions and scientific sections will focus on the high
quality of the submitted papers. Presentations will be mediated by leading mod-
erators. We are glad to receive academics, researchers, engineers and other spe-
cialists within automotive engineering and road transport, students and anyone
interested to attend our congress.

vi Preface
The congress topics underpin the latest trends and scientific development
directions within the field of automotive and transport fields. The target audience
willbenefitfromthemostinnovativesolutionsputforwardbythesubmittedpapers,
within the field of automotive and transport, and further collaboration and profes-
sional networking opportunities that reside in this congress.
The congress has long historical progress, SMAT 2019 being the 30th edition.
Over the time, the congress topics have been actualized permanently, one of the
organizer’s targets being the international visibility and the continued increase in
the scientific content of the papers.
Many remarkable Romanian and international researchers from automotive and
transports engineering will be present to the congress. During the congress acts, a
scientific student contest will be organized and also a roundtable with social and
economic representatives, about security, safety road and urban logistic.
The social, economic, technical and scientific impact of faculty of mechanics
activities, a pillow of the University of Craiova, is finding in a large area of
scientific and technical achievements of students, graduates and researchers of this
faculty, all around the world.
