The optimization of the processing stages in the sawmill line occupies a strategic position in processing wood products from raw materials (logs). The main objectives of this paper are to propose a design and manufacture an automatic edging and trimming (AET) system for a wood board to synchronize with the sawing line using programmable logic controller (PLC) system. To verify the design of integration, 20 different board samples were used to evaluate the effectiveness of the manufactured system. The results indicated that the AET system meets the basic requirements in cutting the edge waste out of the board and improving rate of wood recovery. Therefore, the idea of the AET system displays merits further research and may be applicable to future sawmills

In robotic control sectors, the image-based visual servo method is an advanced approach used to control the robot to the desired position by using pixels from cameras. We can control the robot flexibly to achieve high quality when the joint variables have little backflash. Applications of this method can be classified into two groups: eye-in-hand and eye-to-hand ones. In this paper, we employ the eye-to-hand method for position tracking control problems of robotic manipulators. Kinematics of the robot and camera are first derived based on homogenous transformation relation and pinhole models. The control technique uses the normalized difference between the pixel observed from the camera and the desired pixel to result in proper control signals throughout a flexible activation gain. The feasibility of this method will be demonstrated through comparative simulation results.

In industrial plants, machines and measuring instruments are displayed through a seven-segment display. The machine is operating for more than 20 hours/day. The operator cannot check measurement data or status all the time. In addition, human error affects overall performance and time. This research aims to develop an embedded system for interpreting data from seven segment displays through online image processing. CNN (Convolution Neural Network) is applied in the detection and interpretation process. This paper proposes seven-segment display automatic detection and interpretation system using CNN-GO. An IoT device takes the photo of the measuring instrument's seven-segment display and sends the image to the server. The server interprets an image to numerical data using CNN-GO. Grayscale and Overlapping scanning are applied to increase the accuracy of detection and interpretation of numerical data.

An advanced flywheel-based balance for biped robots is presented to follow the desired gait. Firstly, a dynamic model of hybrid biped-flywheel in walking is built. Then, a new balance controller is designed based on a flywheel located at the upper biped body, which is a closed-loop controller with the feedback signal being the tilt angle of the upper biped body related to the gravity acceleration to keep the biped body parallel to the ground exactly the desired gait. The PD+ controller is implemented whose parameters will be optimized using the multi-objective MO-Jaya algorithm. Eventually, proposed solution is successfully applied for the small-sized biped robot (HUBOT-4.1) to robustly walk in balance along with the desired gait. Simulation and experiment results prove that the proposed solution is effective

With the modern development in the world of vehicles, electric and hybrid vehicles account for a relatively large part of the world in which the powertrain determines the vehicle's performance. To continue developing and synthesizing many novel structures, Yan's method is the optimal method to analyze and synthesize the existing structures. This article proposes a new process of applying Yan's method by arranging the clutches and requirements with the corresponding structures. Then, the structures of five, six, seven, and eight links are synthesized and generated. To demonstrate the feasibility of the structures and create the corresponding operating modes, the 6-link structures are selected to provide adequate torque and working conditions for the electrified vehicles.

A compact Y - Shaped antenna with a defected ground structure for Wireless Body Area Network is presented and is operating in the terahertz frequency range. This antenna is having an impedance bandwidth of 10.519 THz (1.147 THz-11.66 THz) and a microstrip feed line is employed to feed the antenna. By making amendments in patch shape and causing defects in the ground, size reduction of the antenna and substantial enhancement in bandwidth are reached. The antenna is radiating at 2.515 THz, 3.872 THz, 7.287 THz, and 10.084 THz respectively. To get the desired result parametric investigation is conducted and the results are described methodically. The maximal gain of the antenna is 15.07 dB at 7.716 THz.

This study briefs the application of a novel intelligent algorithm as an adaptive filter. The proposed algorithm, Petri fuzzy brain emotional learning-based neural network (PNFBELNN) is designed by introducing Petri Net layers in fuzzy brain emotional learning-based neural network. The Petri Net reduces the computational load caused by parameter learning and improves fuzzy reasoning thus enabling high-speed signal processing. The proposed filter is applied as an adaptive noise canceller. The performance of the filter is illustrated through numerical simulations of the noise cancelation system.

This study presents a design of the multilayer type-2 fuzzy controller (MT2FC) to control the time-varying delay systems. By using the proposed multilayer structure, the number of fuzzy rules can be reduced while ensuring good coverage of input states. The self-evolving algorithm is used to automatically obtain the optimal network structure. The network parameters are updated online using the gradient descent method. Finally, the performance of the proposed control method is illustrated by numerical simulations of the time-varying delay systems.

This paper aims to develop a technique for controlling fuel pressure in a common rail injection system using proportional integral derivative control (PID). Test fuel was blended fuel between diesel and biodiesel of 93:7 %vol. The multiple injection strategies were tested under the injection pressure of 350 to 800 bar. Injection duration was varied in the range of 0.82-5 ms with a constant dwell time of 6.4 ms. Injection period was set as 171 ms, corresponding to the engine idle speed of 750 rpm. Suction control valve was controlled by pulse width modulation. The results showed that fuel pressure in the common rail can be controlled by PID controller for different injection strategies with fluctuation pressure in the rail less than 1%. The fluctuation pressure trends to have lower fluctuation pressure in case of higher pressure.
