The technological development in healthcare experienced in actual days has relationship with the integration of many knowledge areas, fundamentally by searching new solutions in order to improve the quality of life of the society. Examples of this reality appears in medicine and engineering areas, where the computer-assisted techniques works together to solve many healthcare problems. In the surgical procedures context as well, as in dental implant planning, the surgeon still determine some parameters according to his personal experience, where only the visualization of the problems through Computed Tomography images are not enough to ensure the success of the procedure. Thus, this research aims to propose a computational model, as a decision support tool, in order to define a more appropriate positioning for dental implants. This is a fundamental part to determination of the necessary parameters for the process planning because the information is obtained automatically straight from image processing. The prototype presented in this work comprises a user-friendly interface, which allows dentists to observe the bone and dental structure in multi-perspective images. Also, it determines the implant location by an automatic procedure without intervention of dentist. The text shows a study case with the autonomous determination of an implant position. © 2015 IEEE.

The problem of failure occurrence in flexible manufacturing systems (FMS) tends to increase according to their complexity leading to time-consuming tasks as the localisation and repairing. The occurrence of failures during the exploitation stage can deeply modify the FMS performances or its availability. We want to investigate the maintenance integration into a control-monitoring framework, from the control system's early design stage to the maintenance policies execution, so as to improve production time and minimize unplanned costly breakdowns of FMS. This paper proposes a modular and hierarchic control-monitoring-maintenance architecture (CMM) for FMS based on Petri nets with objects (PNO). These efforts acts as a basis for the control architecture of a robot-driven flexible cell, connected to the Ethernet-TCP/IP. © 2006 IEEE.

Advanced conceptions to design industrial control systems are, in general, dependent of mathematical models of the controlled process. Also, the task of the controllers is to achieve an optimum performance when facing with various types of disturbances that are, sometimes, unknown in practical applications. An advanced methodology for control design is the variable structure control (VSC) with sliding mode. This paper considers the non-linear control of industrial processes based on self-tuning discrete VSC technique. A novel and systematic VSC design methodology is proposed, which integrates an estimator based on recursive least square algorithm, a discrete quasi-sliding surface and a optimization method. Contrary to the trial and error selection of the variable structure feedback gains reported in the literature, the selection in present work is done using differential evolution (DE) optimization, an evolutionary computation technique, with a new operator based on normative knowledge of cultural algorithms. The proposed design has been applied to a control valve described by a non-linear Wiener model. Numerical simulation results reveal that the new DE approach is applicable and promising for the VSC design. Copyright © 2006 by ASME.

Particle swarm optimization (PSO) is a population-based swarm intelligence algorithm that shares many similarities with evolutionary computation techniques. However, the PSO is driven by the simulation of a social psychological metaphor motivated by collective behaviours of bird and other social organisms instead of the survival of the fittest individual. Inspired by the classical PSO method and quantum mechanics theories, this work presents new Quantum-behaved PSO (QPSO) approaches using mutation operator with exponential probability distribution. The simulation results demonstrate good performance of the QPSO in solving a well-studied continuous optimization problem of mechanical engineering design. Copyright © 2006 by ASME.

This paper presents a new discrete-time sliding-mode control design for multiple-input multi-output (MIMO) systems with tuning parameters by particle swarm optimization (PSO). PSO is a kind of evolutionary algorithm based on a population of individuals and motivated by the simulation of social behavior instead of the survival of the fittest individual. Several control algorithms are presented, two decoupling design and six new approaches of the coupling design of sliding-mode control without the necessity of calculate the process interactor matrix. SMC needs a design tool for parameter configuration and efficient practically to deal with multivariable processes. Simulations are carried out using both decoupling and coupling discrete-time SMC designs. Results shown that the new proposed approach for designing the discrete-time coupling SMC is a powerful tool and it performs better than the decoupling design, usually utilized in MIMO process. The simulations are assessed on a robotic manipulator of two degree-of-freedom (2-DOF), that constitute a MIMO nonlinear coupling dynamic system, with treatment of payload mass and link length variations. Simulation results show that the application of this control strategy effectively improve the trajectory tracking precision of position and velocity variables. Copyright © 2006 by ASME.

International Conference on Remote engineering and Virtual Instrumentation (REV)

WebLabs, or Remotely Operated Laboratories, allow for remote control and monitoring of interactive or batched systems with educational objectives. Considered as additional resources in education, they contribute to a flexible learning model and make possible for students to perform laboratory experiments remotely, off-class, in collaboration, thus contributing to the reduction of laboratory equipment idleness. The purpose of this paper is to report steps in designing and enabling a WebLab with background theme on the control and monitoring of thermal comfort parameters in a newborn baby incubator. Three didactical experiments can be performed in this WebLab: transfer function evaluation, on-off control and PID controller tuning, with users challenged to optimally tune the parameters of a controller algorithm. In the end of the session, the user can enter his/her impressions regarding the WebLab usage by answering a questionnaire. The WebLab design includes the evaluation of students' abilities through performance indexes while keeping operation within the requirements of an associated medical safety standard. A systematic approach for the WebLab design process has been employed, with the system design split in three layers: physical system, hardware and software. Sets of qualitative and quantitative requirements to be attended were defined. system and product design techniques, such as House of Quality, Morphological Matrix and Pugh's Method, have been employed to address the conversion of the project requirements into the Weblab overall solution. Virtual Instrumentation resources have been used to acquire temperature, humidity and air speed signals. The LabVIEW platform was used to support experiment integration and to create the user interface using LabVIEW Remote Panel architecture. The WebLab has been successfully implemented and presently can be accessed within the university network.

The efficiency levels at which companies turn inputs into outputs may increase their competitive capacity. Nevertheless, in the literature, there is a lack of methods allowing evaluation of the performance of operations in production systems that take into account all of their components. The objective of this study is to present an analysis of efficiency for a production system using DEA and OEE in an integrated manner (DEA/OEE). To achieve this objective, we conducted a case study of a bus manufacturer and a comparative analysis using the results obtained by DEA/OEE compared with the results of the OEE measured in an operation of the company studied. The efficiency measured by DEA/OEE presents differences in relation to OEE results. The analysis of the causes of such differences pointed out that action taken to improve the OEE indicator decreased the efficiency of the operation analyzed. This study evidences that decision-making focused on improving OEE on its own may lead to an increase in the consumption of resources during an operation. Such an increase does not necessarily increase production levels and may reduce technical efficiency. © 2020, Global Institute of Flexible systems Management.
