The Aspects of Technology Culture in IT Higher Education -The Cultural Aspects of ICT

Ljubica POPOVIĆ, Djordje ĆOSIĆ, Srdjan POPOV

The aim of the paper is to draw attention to a very important aspect of ICT and encourage readers to consider the significance of technology culture. The success and competitiveness of future IT engineers largely depend on the development of the following skills: creativity, critical thinking, communicative skills, cooperation, and, most importantly, awareness and acceptance of the cultural dimensions of their future associates and IT service users. This was confirmed by Hofstede on a survey of 60,000 respondents, who partly came from the ICT sector. Thus, it is necessary for IT engineers to develop their technical competencies through the implementation of technology culture, during their studies, preparing them for all the challenges of the job market. Technical competencies must be developed in order to practice responsible engineering and innovate the notion of the IT sector.

Analysis of Available Data and Parameters in the Process of Forensics of Unmanned Aerial Vehicles

Advances in information technology have made unmanned areal vehicles (drones) easily accessible to everyone. The use of drones is becoming increasingly present in companies pursuing the most diverse lines of business, as well as in households and even in education, which consequently leads to an increase in their sales. As production has become more substantial in terms of amounts, there is naturally a difference in performance, quality, price as well as their application.  The paper shows the use of different methods of forensic analysis on the information available within the drones themselves, as well as the physical traces on them. In addition to the comparative analysis of forensic analysis methods, it is important to point out that the aim of the paper is to show whether certain data obtained here can be used for their mutual control and management.

Analysis of Positioning Accuracy of Prototype Machine Tools with Hybrid Kinematics

Machine tools with a hybrid kinematic structure represent an unconventional type of machine tools whose characteristics depend on the kinematic configuration. Therefore, it is necessary to perform a separate accuracy analysis for each machine configuration. The analysis of the characteristic values obtained by examining the accuracy of positioning is the starting point for further improvement and calibration of this type of machine. In the case of conventional machine tools with a serial kinematic structure, appropriate standards and recommendations are used to evaluate the state of the machine through testing the positioning accuracy. The paper describes the preliminary measurement of the condition of the machine tool with the hybrid kinematic structure “O-X glide” according to the ISO 230-2 standard, carried out in order to adjust the mechanical subassemblies of the machine, which precedes the process of calibrating the machine’s control system.

3D Vehicle Pose Estimation from an Image Using Geometry

Nikola STOJANOVIĆ, Vasilije PANTIĆ, Vladan DAMJANOVIĆ, Srđan VUKMIROVIĆ

3D pose estimation is a quite fascinating problem in the computer vision field, which aims to get the 3D orientation of the object based on the 2D image and can be challenging to find the solution. These solutions are mostly used in the autonomous industry to properly detect cars’ orientation on street scenes. Most solutions and publicly available datasets refer to only one axis orientation (axis parallel to the road), while two others are set to zero. In this paper, we propose a new way of representing a 3D object orientation that is not limited only to the autonomous industry. Our proposal uses Euler angle representation and two coordinate systems (one from the camera and one from the detected object) to define the angle orientation for each axis in 3D space. Because this approach is supposed to be used in creating datasets and solutions in the deep learning field, there are some restrictions to be considered to properly train your solution. To better represent the proposal of 3D orientation and its purpose, it is necessary to visualize the bounding box around the detected object, which will follow its orientation. The visualization part is being done using computer-generated images (CGI), while the algorithmic part uses quaternions instead of Euler angles for the rotation of the 3D bounding box.
