Autonomous Vehicle Guidance
Dragorad MILOVANOVIC, Dragan KUKOLJ, Sandra NEMET
Recent advances in autonomous vehicle guidance have encouraged further investments in industry and academia. Driverless vehicle technology is nowadays successful in a high percentage of common road scenarios. However, new research efforts are required to meet the demand for higher performance. Visual requirements and recent advances in development of UltraHD formats, as well as omnidirectional video and LiDAR sensor systems are presented in this paper. Also, an MPEG 2020 technology roadmap of video codecs is pointed out.
Food Storage Quality: Status of Technology Through Patent Analysis
Dragan KUKOLJ, Gordana OSTOJIĆ, Stevan STANKOVSKI, Sandra NEMET
In order to access trends on defined topics of interest, analysis of patent databases is becoming everyday practice. In addition, companies analyse patent data and use the obtained results for making market strategies and R&D plans. As food storage safety is one of the most arguable topics in the last decade, this paper shows qualitative and quantitative analysis of patent portfolio created on this topic using publicly available patent search engines. Conducted patent analytics can be used by not only marketing function in the food safety industry, but also to determine trends driven by customers’ demands on food traceability.
Trends in Producing Personalized Bone Implants Using Additive Manufacturing
Miroslav TRAJANOVIĆ, Milica TUFEGDŽIĆ
Additive Manufacturing (AM), formerly known as Rapid Prototyping (RP), enables quick production of personalized bone implants using different techniques and materials. Therefore, there is a need to examine the possibilities for AM application in the field of orthopedics and prosthetics and to provide an overview of current state. Progress done in the area of biomaterials is presented from the perspective of different AM technologies used. Patient specific implants and prostheses in different branches of surgery and implantology, as well as some examples in tissue engineering are shown. The results are presented in the form of systematic review, bearing in mind challenges and future trends related to bone healing and regeneration.

Real Time Tool Condition Monitoring System Based On Texture Descriptors
Aco ANTIĆ
All state-of-the-art TCM systems, especially those that use vibration sensors, in the tool wear recognition task, heavily depend on the choice of descriptors that contain information concerning the tool wear state, which are extracted from the particular sensor signals. We consider the module of the Short Term Discrete Furrier Transform (STDFT) spectra obtained from the particular vibration sensors signal utterance, as the 2D textured image. This is done by identifying the time scale of STDFT as the first dimension, and the frequency scale as the second dimension of the particular textured image. The obtained textured image is then divided into particular 2D texture patches, covering part of the frequency range of interest.
