Abstract In this paper, we address the problem of monitoring the cardiovascular system through the integration of automatic tools. This monitoring is to detect heart diseases starting from the electrocardiographic signal (ECG). In particular, we propose a method for detection of defects in the ECG signal analysis exploring the non linear principal components (NLPCA). The data matrix consists of 528 measurements... In this paper, we address the problem of monitoring the cardiovascular system through the integration of automatic tools. This monitoring is to detect heart diseases starting from the electrocardiographic signal (ECG). In particular, we propose a method for detection of defects in the ECG signal analysis exploring the non linear principal components (NLPCA). The data matrix consists of 528 measurements and 9 variables, these variables are determined from waves and segments of the ECG. The proposed approach allows to reduce the size of the data matrix and find the linear and non-linear relationships between variables. Defect detection is established by the statistical SPE (square predictive error) which is based on residues. Defective variables are found by calculating their contributions, its have the highest contributions. Read More Read Less

Control of flexible manufacturing systems requires the adaptation of the software components to the constraints imposed by the hardware components. As a key element of the control of flexible manufacturing systems, the control of an industrial robot is an essential first step towards the control of a whole cell. This step provides a wide field of investigation given the multitude of algorithmic combinations leading to the control of the robot. On the other hand, the optimization of such a command is an important task because of the effects it may have on the command of the whole cell. In this paper, we propose an algorithmic approach for the control of an industrial robot. Our approach is based on a dynamic data exchange (DDE) between the control and the operative part of the system. The exchanged data allows the control of the system and the information about its status. This exchange needs synchronization between the various software components of the system. The approach is implemented through a win32 software allowing the manipulation of an Adept Cobra 600 industrial robot. Read More Read Less

Abstract Position and force ripple are the major disadvantage of linear switched reluctance motor (LSRM), thing that can reduce the integration in high precision application.

The work developed in this paper is a novel method to control this actuator in order to increase his performance. A model of the actuator is performed neglecting magnetic saturation. In order to make a smooth motion of the motor open and speed closed loop control are detailed and tested in this paper, this paper reports a study of speed control using a PI controller, hysteresis controller and force distribution function (FDF).

Abstract A printing system may have unrestricted printing area and no moving parts. The printer is a handheld device which when swiped over the paper to be printed, prints out the required data properly irrespective of the movement of the device. It also hints areas which are yet to be printed.... A printing system may have unrestricted printing area and no moving parts.
