1. Analyzing the competences of production engineering graduates: an industry perspective
Abstract This paper aims at conducting an analysis the competences of production engineering graduates, building on an industry view. To this end, we conducted a survey addressing 103 medium and large companies within the Brazilian manufacturing industry. The results suggest that companies do recognize the importance of competences. Some gaps in the competen

2. Mathematical Description of a Flexible Connection of Links and its Applications in Modeling the Joints of Spatial Linkage Mechanisms
Abstract The general mathematical model of a flexible connection of links by means of spring-damping elements is presented in the paper. The formalism of homogeneous transformation matrices is used to derive formulas for the energy of spring deformation and the Rayleigh dissipation function of the spring-damping elements. The formulas have convenient forms t

3. Más allá del malestar. Una hipótesis sociológica sobre el significado político del movimiento estudiantil chileno
The irruption of Chilean student movement required to be addressed in sociological terms. So far, the predominant reading regarding the tensions and conflicts that student demonstrations have left to emerge is limited to describe how the economic logic of educational policies, driven by different Chilean Governments for these past thirty years, have caused g

6. Simultaneous control and piezoelectric insert optimization for manipulators with flexible link
This work proposes a tracking control model for a flexible link robotic manipulator using simultaneously motor torques and piezoelectric actuators. The dynamic model of manipulator is obtained in a closed form through the Lagrangian approach. The control uses the motor torques for the tracking control of the joints and also to reduce the low frequency vibrat

7. Stiffness Study of Closed Kinematics Chains / Estudo de rigidez de cadeias cinemáticas fechadas
Multibody systems consist on a kinematic chain composed of links that can be rigid or flexible, interconnected by joints. The multibody systems are of great importance and are used in various applications such as in aerospace and automobile engineering, machine tools, mechanisms, sea exploration, medicine and robotics. An example of multibody system that has

8. Improving traceability in agent oriented development
Requirements engineering has argued that in order to successfully develop complex software systems, it is necessary to support the modeling process with traceability mechanisms and tools. Requirement Traceability refers to the ability to ensure continued alignment between stakeholdersâ requirements and various outputs of the systems development process. A r

9. Estratégias de gerenciamento de banda IP/MPLS para o transporte eficiente de serviços integrados
To use the network resources in the optimal efficiency one possibility is apply resource management policies that can be flexible and feasible as much as the time period can be. The converged networks are expected to deliver audio and video transmissions with quality as good as that of a circuit switching network. In order to make it possible, the network mu

10. DEVELOPMENT OF A THREE DEGREE-OF-FREEDOM PNEUMATIC LINK FOR FLEXIBLE ROBOTIC MANIPULATORS / DESENVOLVIMENTO DE UM ELO PNEUMÁTICO DE 3 GRAUS DE LIBERDADE PARA MANIPULADORES ROBÓTICOS FLEXÍVEIS
Recently, the concept of flexible manipulators has attract great interest. These devices present a continuously deforming vertebral column, in opposition to the traditional robotic manipulators link/joint/link with rigid links. Flexible systems offer a potential increase in the capacity of interaction with the environment, being apt to adjust itself to the c

11. A new robotic drive joint friction compensation mechanism using neural networks
The knowledge of realistic dynamic models to robotic actuators would be of great aid in the synthesis of control laws to robot manipulators, mainly in cases of great precision robotic or even for manipulators with flexible links. In this paper we present a training scheme and propose a structure of neural network (NN) to learn the friction torque of a geared

12. Dinâmica e controle de movimento de corpo rígido de um manipulador robótico rígido/flexivel / Dynamic and control of rigid body motion of a rigid/flexible robotic manipulador
This work presents a study of the dynamics and control of the movement of rigid body of a robotic manipulator. The model of the manipulator, consisting of a mechanism with two flexible links hardwired by meetings that do not suffer deformations, was gotten through the Formularization of Lagrange and the Admitted Modes Method. For matching effect, two other m
