1. General exact harmonic analysis of in-plane timoshenko beam structures
The exact solution for the problem of damped, steady state response, of in-plane Timoshenko frames subjected to harmonically time varying external forces is here described. The solution is obtained by using the classical dynamic stiffness matrix (DSM), which is non-linear and transcendental in respect to the excitation frequency, and by performing the harmon

3. Algoritmos para problemas de corte e empacotamento / Algorithms for cutting and packing problems
Several versions of Cutting and Packing problems are considered NP-hard and, if we consider that P ¿ NP, we do not have any exact polynomial algorithm for solve them. Practical applications arises for such problems and include: resources allocation for computers; cut of steel, wood, glass, aluminum, etc.; packing of objects; and, loading objects into contai

4. Simulation software development for multibody systems / Desenvolvimento de uma ferramenta computacional para simulação de sistemas mecânicos multicorpos
The mathematical simulation is a very important tool to reduce production costs in new projects of agricultural machines. This work consists of a simulation software development for multibody systems (MBS), called FSSM (tool for simulation of mechanical systems), with appropriate functionalities for manufacturers of agricultural machines, using the AutoCAD g

5. Descrição de rotações : pros e contras na teoria e na pratica / Representation of rotations: advantages and disadvantages in theory and practice
Robótica, computação gráfica, aeronáutica e biomecânica têm em comum o estudo de movimentos rígidos, aqueles compostos por rotações e translações. Ao contrário das translações, cuja representação matemática não apresenta dificuldades, as rotações trazem consideráveis desafios. Neste trabalho de mestrado estudamos algumas propriedades do

6. A model of nervous system for the problem of the control of animation for direct dynamics. / Um modelo de sistema nervoso para o problema do controle de animaÃÃo por dinÃmica direta.
Direct dynamics animation consists of synthesizing the movements of a model from the specification of its physical properties (mass and moment of inertia), the conditions of bond between its contracting parties, the conditions of contact with other bodies and the forces that acts on it. This approaching has the advantage to generate animations with physical

7. Dynamic simulation of constrained mechanical systems using recursive projection algorithm
In this paper, the dynamic simulation of constrained mechanical systems that are interconnected of rigid bodies is studied using projection recursive algorithm. The method uses the concepts of linear and angular momentums to generate the rigid body equations of motion in terms of the Cartesian coordinates of a dynamically equivalent constrained system of par

9. A Design Methodology for the Compensation of Positioning Deviation in Gantry Manipulators
This work presents recent results concerning a design methodology used to estimate the positioning deviation for a gantry (Cartesian) manipulator, related mainly to structural elastic deformation of components during operational conditions. The case-study manipulator is classified as gantry type and its basic dimensions are 1,53m x 0,97m x 1,38m. The dimensi

10. Animação dinamica de corpos rigidos articulados
This work presents a dynamic simulator of articulated rigid bodies. The bodies are described by their physical and geometric properties and are assumed to be convexo The input for the simulator is, in addition to the description of the bodies, an initial valid state and a set of external forces and torques that act on the bodies over the time. Articulations
