• Environmental Control of a Greenhouse System Using NI Embedded Systems TechnologyEnvironmental Control of a Greenhouse System Using NI Embedded Systems Technology

    We have presented the application of an automated greenhouse system using NI Embedded Systems Technology. The system is instrumented with sensors and actuators and controlled by an embedded cascaded PID algorithm in order to provide accurate control of the air temperature within the greenhouse. A simulation model of a subsystem has also been ...

  • Control of Quadrotor Unmanned Aerial Vehicles Using Exact Linearization Technique with the Static State FeedbackControl of Quadrotor Unmanned Aerial Vehicles Using Exact Linearization Technique with the Static State Feedback

    It is known that the q-UAV system is 4-input 4-output Affine nonlinear system of degree 12 and that it can not be exact linearizable by the static state feedback. So, to apply this control technique, it is necessary to augment the total system of the q-UAV by introducing two integrators. In this paper, we suppose that the vertical position is...

  • A Redundancy and Operation of Power Control System for a Deep-Space Small ProbeA Redundancy and Operation of Power Control System for a Deep-Space Small Probe

    The Shinen2 was launched in December, 2014 and had three types of communication lines: a Communication line (C-line), an Amateur Radio Relay Experiments line (A-line) and a Beacon line (B-line). The A-line and Cline were used for the specific communication modulus, WSJT, which was able to communicate with the low power transmitter in space. T...

  • Active control of a three-Story building using hedge-algebras-based fuzzy controllerActive control of a three-Story building using hedge-algebras-based fuzzy controller

    The algebraic approach to term-domains of linguistic variables is quite different from the fuzzy sets one in the representation of the meaning of linguistic terms and the methodology of solving the fuzzy multiple conditional reasoning problems. It allows linearly establishing the Quantifying Semantic Curve through the points corresponding to the ...

  • Experimental study of laminar separation phenomenon combining with numerical calculationsExperimental study of laminar separation phenomenon combining with numerical calculations

    The experimental work combining with numerical calculations permits to deduce some following remarks: - Separation positions of the considered laminar flows are similar when comparing experimental results and numerical results. - Laminar flow regime is very sensitive to the boundary layer separation, much more than in comparison with turbulent...

  • Dynamic characteristics of elastically supported beam subjected to a compressive axial force and a moving loadDynamic characteristics of elastically supported beam subjected to a compressive axial force and a moving load

    The paper investigated the dynamic characteristics of elastically supported beam subjected to an eccentric compressive axial force and a moving point load. The equations of motion for the system have been constructed by using the Galerkin finite element method. The time histories for normalized mid-span deflection and the dynamic magnification f...

    The optimum solution aimed for exploitation of machinery life, obtained in the described manner, should not be directly recommended for accepting and application to the management of a mining company. It is required primarily to carry out the overall economic analysis that includes the analysis of sensitivity, analysis of efficiency and the ana...

    In this paper, we introduce a novel algorithm for motion style transfer task. Our method is an integration of matrix factorization and an artistic style learning technique. This work can deal with a shortage of large motion datasets since it can be applied to small ones. In spite of gaining some promising outcomes, there are several limitat...
