    • A SOLID BODY SURFACING MATHEMATICAL MODEL IN STRATIFIED INCOMPRESSIBLE FLUID UNDER THE ACTION OF BUOYANCY FORCE AND LIMITED MOTION CONTROL

      pg(s) 109-111

      This paper results are based on the mathematical model of the motion control of an autonomous solid body in stratified incompressible fluid which was presented by the authors at XII MTM Congress held in September 2015 and XIV MTM Congress held in September 2017. This paper presents an analytical mathematical model of a solid body, which surfaces in stratified viscous incompressible fluid, a difference scheme and its solution. The body is equipped with controlled rudders, wings of finite span, and does not have its own propulsion system. It is moved by the influence of the buoyancy force and wings lift effect. This body motion is considered to be planeparallel motion. The mathematical model synthesis is based on the hydrodynamic equations.

    • SECURE AND EFFICIENT CLOUD COMPUTING ENVIRONMENT

      pg(s) 112-114

      The cloud computing environments are cost and productivity efficient, they are quickly replacing the traditional centralized systems. These “clouds” inherit a lot of security concerns of the older systems, but also bring the new ones. This paper examines 3 most popular cloud vulnerabilities, as well as a vulnerability intrinsic to the cloud environments. It proposes solutions and classifies the risks.

    • GENETIC MODELING AND STRUCTURAL SYNTHESIS OF CNC MULTI-SPINDLE AUTOMATIC MACHINES OF NEW GENERATION

      pg(s) 115-119

      Global trends on the key technical and economic indicators in development of multiple-spindle automatic machines (MSAMs) with various control systems and the hybrid MSAMs with consecutive reduction and complete elimination of mechanical kinematic chains, developed with the use of electromechanical structures (EM-structures) in I. Sikorsky KPI, are given in this paper. Genetic synthesis of MSAM EM-structures by the defined search function using genetic synthesis models and genetic operators of crossing, replication and a mutation have been made here.

    • MODELING AND SIMULATION OF VEHICLE AIRBAG BEHAVIOUR IN CRASH

      pg(s) 126-129

      Since safe transportation is one of the biggest concerns of vehicle manufactures, occupant safety in vehicle accidents becomes a great challenge.
      The severity of the crash reflects the energy absorption of the car’s structure during the accident and also has a close relationship with the amount of energy absorbed by the restraint system. Among components involved in restraint system, airbags are the most complex ones. The simulation and modelling of this system due to the nonlinear behaviour of the passenger and the vehicle add more complexity to its design and fabrication. Airbag system, which is a subsystem of the restraint system, is very important due to the nature of its multi-physical problem and the direct connection with passenger safety.
      Therefore, in this paper, different approaches to develop airbag dynamics equations has been reviewed. Further a fast design and simulation method for airbag parameters in the concept design phase by an impact problem has been investigated to contribute to a comprehension of the relation between occupants and airbags.

  • DOMINANT TECHNOLOGIES IN “INDUSTRY 4.0”

    • INDUSTRY 4.0: REQUIRED PERSONNEL COMPETENCES

      pg(s) 130-133

      The rise of Industry 4.0 and of smart factories along with all enabling technologies such as cloud computing, Internet of Things, multi agent systems, cyber physical systems, artificial intelligence, etc. will transform current factory workers to knowledge workers. Hard work and routine tasks will be executed by machines or robots, while tasks requiring experience, intuition, creativity or decisions making based on uncertainty will still reside to humans. This constitutes a huge shift on the required competences. Further, this change is transforming manufacturing to a software intense business, where software development and operation is a core part of the manufacturing process, but as well as of the products being manufactured either as a standalone component or as a part of a larger product or service. The need is prominent, since we need urgently to study the knowledge and competences needed for manufacturing personnel of the near future. In this paper, we present an initial competence model where will outline the knowledge dimensions and skills needed for Industry 4.0. This model can be used to create training proposal individuals or for assessing the knowledge gaps existing in an enterprise. The identified skills are classified as technical, behavioral and contextual.

    • TESTING THE SYSTEMS OF THE AUTONOMOUS AGRICULTURAL ROBOT

      pg(s) 134-137

      The aim of the paper was to test of the concept of the navigation system for the autonomous robot for sowing and wide row planting. Autonomous work of the robot in the field of traction and agronomic processes is implemented based on data from many sensors (cameras, position sensors, distance sensors, and others). The robot is intended for ecologic cultivation requiring mechanical removal of weeds or in crops with application of selective liquid agrochemicals limited to the minimum. The use of a vision system, based on the map coordinates of the position of the sown seeds, allows for their care on an early stage of plant development. Main sensor system is based on a specialized GPS receiver and inertial navigation providing position information with an accuracy of around 10 mm. To determine the angular acceleration the IMU (Inertial Measurement Unit) is used. Additionally, information from the acceleration sensors and wheel encoders is used for navigation purposes. This system is used to: control the speed of the robot, keep the robot on the designated path, and detect the precise position of the seeds. The exact information of the seeds position is used to build maps of seeds, which will be used as supporting information for precision weeding, and to control the position of and operation of key components. The front camera view is used to increase positioning accuracy of the robot. It will allow corrections of the robot path regarding the rows of plants. The vision system is also used for detection of non-moving objects. A structure of requirements for the SQL database has been developed, which is used to store plant and weed geo-data, as well as store data about plants and weeds, based on images recorded by the vision system.

    • WAVELET ANALYSIS OF ACOUSTIC SIGNALS

      pg(s) 138-140

      In modern warfare there has been increased use of various weapon systems like tanks, artillery, mortars, infantry armored vehicles, multiple launch rocket system (MLRS). Hostilities often are conducted in densely populated urban areas, where most victims are given by the civilian population. It is the application of systems of detection and reconnaissance sources of sound (the weapons), and also the quick disclosure of their locations. It achieves a “rapid response” of the threats and reduces casualties. Wavelet analysis offers a quick way to process acoustic signals received in the shooting which provides the opportunity for quick reconnaissance and defining sources of sound.

    • FEASIBILITY STUDY FOR THE IMPLEMENTATION OF EDI SYSTEMS FOR INFORMATION EXCHANGE BETWEEN BULGARIAN BLACK SEA PORTS AND ECONOMIC OPERATORS

      pg(s) 144-147

      The present article analyses the feasibility for design and implementation of Electronic Data Interchange (EDI) systems for documentary exchange between Bulgarian Black sea ports and economic operators. The concept of the Port Community System (PCS) is analysed as a necessary information exchange framework for implementation of EDI systems. The main economic operators are identified and their interactions within the port community system are formalised. A methodology for implementation of EDI system has been developed along with the main information flows. The benefits of EDI implementation are outlined as means for increasing ports competitiveness.
