The study implements a mathematical and visual analysis of the universal joint's work in the software package MathCad and MATLAB Simulink. We obtained the dynamic model taking into account internal characteristics. It demonstrates the connection of the torque on the crosspiece with the angular velocity of the driveshaft and allows to find and fix errors in the early stages of design. [ABSTRACT FROM AUTHOR]

We are in the brink of the next disruptive technology in the automobile revolution. The autonomous vehicles will have the direct impact on our society and the way we move and live. The autonomy means "autos" (self) and "nomos (rule). The definition of autonomy is the ability of an individual to make a rational, uninfluenced decision. The autonomous vehicle must follow the principles of autonomy like humans, making fair decisions at all situations. To navigate to a given destination based on passenger provided instructions, autonomous vehicle must observe, understand, model, infer, and predict behavior of the surrounds like, weather, animals, debris, follow the traffic rules and signals, and the humans inside and outside the car and finally make a split-second decision. The social, economic, ethical, human behavior, urban and suburban landscape, insurance, legal and liability, and ethnographical effects are enormous. These aspects must be considered for the development of the autonomous vehicle. This paper would examine the challenges in developing autonomous vehicle. [ABSTRACT FROM AUTHOR]

Civil Infrastructures regardless sector they belong to as hydraulic (dams, pipelines), transport (bridges, roadways) or building represent a fundamental element for our lives quality and improvements then considering the continuous technological progress, existing infrastructures have to be adjusted in order to cohabit with innovations or to be complementary to new constructions. For these reasons it is important to guarantee their complete efficiency with correct maintenance operations but especially monitoring ones so to forecast imminent damages, considering that during its life cycle a generic infrastructure is subjected to dynamic and various loads, deterioration of materials and atmospheric agents that can compromise its functionality. Such aspects result fundamental considering that in many developed countries as Europe most of existing bridges were realized in world war two decades, then for example in USA 70% of roads and bridges was realized before 1930s while in Japan majority of bridges was built in 1970s. Nowadays technologies used for monitoring interventions or inspections are several but most of them are intrusive and require the need of certified human operators, these aspects create a significant safe risk and cost increase both for operators payment and equipment, then the service that an infrastructure has to provide is compromised as for example traffic interruption for bridges. In last decades to solve critical issues due to operators cost and safety or services interruption, UAVs (Unmanned Aerial Vehicles) commonly known as drones were used for monitoring operations, such systems have several advantages mostly because they are not intrusive and do not require a human operator. For these reasons especially due to cost reductions, UAVs for civil engineering infrastructure are expected to reach €40 billion market worth in next decade. [ABSTRACT FROM AUTHOR]

Digital and technological innovations that have grown rapidly in recent years have been referred to as the 4th Industrial Revolution or Industry 4.0. The fourth industrial revolution as a whole will decisively reshape all phases of the process of investment preparation, their implementation and the subsequent administration and maintenance of buildings. These changes will fundamentally affect most construction professions and will require changes in their knowledge and skills. Some professions will disappear, some will be newly constituted, which will require a new constitution of lifelong learning systems. Ensuring the competitiveness of the Czech Republic and the Czech construction industry will require purposeful monitoring of these trends, support for research and innovation, support for start-ups and support for small and medium-sized enterprises in particular and their approaches to these innovations. It seems as if the construction industry is somewhat aside. The big topic in present construction is BIM (Building Information Modeling), but this is just one component of the considered Construction 4.0. Other topics, if not completely neglected, are minimally delayed. Nevertheless, it is important to deal with them. These include virtual and augmented reality, 3D printers, advanced building materials, prefabricated and modular designs, Big data and predictive analytics, 3D scanning and photogrammetry, autonomous vehicles and drones, cloud collaboration (real-time collaboration) or wireless monitoring and connecting equipment. The paper comprehensively deals with the description of the Construction 4.0 with a focus on the environment of the Czech Republic and on transport construction. The content is complemented by an assessment of the current situation, indicating the possibility of use in practice. [ABSTRACT FROM AUTHOR]

Vehicle technologies can be designed to reduce the number of crashes and save thousands of lives every year. Today, technological advances have brought to the forefront a new generation of intelligent devices that exemplify a breakthrough in driver safety and collision avoidance sophistication. Although today’s vision devices are capable of capturing images, the implementation of Intelligent Smart Real Time Vision (ISRTV) devices will capture/detect high-level descriptions of a scene and analyze object movement (Figure 1). These devices could support a wide variety of applications including human/animal/object detection, surveillance, motion analysis, and facial identification. The use of Intelligent Smart Real Time Vision devices as embedded systems inside a modern vehicle can minimize driver distractions and significantly improve driver safety. This development of automotive real time visioning sensors are widely utilized by the majority of the OEMs. Consequently, educators are redesigning curricula to prepare students for positions requiring the skills to solve advanced real-world automotive safety challenges. The objective of this paper is to develop a multi-discipline ISRTV diverse student education platform on vehicle safety and collision avoidance, focusing on embedded systems through the integration of acoustic cameras, as a real time visioning system with control algorithms.
