STL (stereo lithography) format is the de facto file for rapid prototyping manufacturing. However, it suffers from its drawback in a high degree of redundant vertices. Furthermore, errors in the tessellation process cause inconsistency and incompleteness in the STL file. The purpose of this paper is to present how to simplify STL triangular mesh and get its optimized shape for rapid prototyping manufacturing. The processes for the STL mesh re-triangulation can be set to mesh deletion and mesh reconstruction. In the mesh deletion process, two kinds of weighted value algorithms are used for determining the suitable value of STL meshes deleted. In the process of STL mesh reconstruction, genetic algorithm with its fitness functions is implemented for the optimization of the STL meshes. Two cases of the STL meshes re-triangulation are shown to prove the processes presented in this paper are in good results.

This research focuses on the development of a rule-based intelligent equipment maintenance platform using JAVA expert system shell (JESS) technology for equipment breakdown diagnoses. A prototype system is designed and developed combining rule-based knowledge system and inference engine to support real-time collaborative equipment maintenance across geographical boundary. The main modules and functions of the system include diagnosis knowledge management, project (case) management and system administration. The knowledge management module includes key functions such as knowledge type definition, knowledge component definition, document definition, mathematical model definition, rule and rule-set management. The project (case) management module includes key functions such as project definition, project's role management, project's function management and project's rule-set execution. Further, the example of a TFT-LCD production equipment breakdown diagnoses is illustrated to demonstrate the development of the intelligent system for achieving agile collaborative manufacturing processes with real-time equipment diagnosis and maintenance.

The issue of multi-robot formation is address in this paper. Usually robots can only handle local information described by an adjacency graph. We define structure error of formation based on the graph theory and propose a local control strategy for individual robot based on NN control with robust term which can ensure robots converge to a unique formation. Furthermore we discuss the performance on two aspects: the first one is dynamic characteristics during formation process; the second one is obstacle avoidance during formation.

Recursive matrix relations for kinematics and dynamics of a new delta parallel robot with concurrent prismatic actuators are established in this paper. This parallel mechanism consists of several kinematical closed chains. The three active elements of the sliding manipulator, acted by some horizontal concurrent forces, which are generated by some hydraulic or pneumatic systems, have three independent translations. Knowing the translation motion of the platform, one initially develops the inverse kinematical problem and determines the positions, velocities and accelerations of the manipulator. Further, the virtual power principle is used in the inverse dynamic problem. Some matrix equations offer iterative expressions and graphs for the actuating forces and powers of the three actuators.

Behaviors of micro bubbles and droplets have been analyzed by tomography methods such as an algebraic reconstruction technique (ART) and a multiplicative algebraic reconstruction technique (MART). In this study, the size, location and shape of bubbles and droplets have been calculated. This technique can be used for ejection of micro droplets or analysis of bubble behaviors in a micro channel. Two tomography methods have been compared to obtain more accurate results of the two-phase flows. Initially, a bubbly flow and an annular flow have been investigated by cross-sectional views using computer-synthesized phantoms. Then, the reconstruction of three-dimensional density distributions of phantoms with two and three micro bubbles have been accomplished by the MART method which provided the better results for the two-dimensional reconstructions accurately to analyze the bubble behaviors in the micro flow.

This paper presents techniques for system design and control of a vertical linear motion system driven by a tubular linear induction motor (TLIM). A new tubular linear induction motor is designed for propelling the elevator to move up and down. With the motor a control system for the motion system is presented. In order to overcome the parameter variations caused by the TLIM, a robust PID is used. Experimental results have shown that the proposed system together with the control is capable of giving desirable performance.

This study presents the design and manufacture of a prototype of a multi-detector triangulation laser probe. The developed system was configured and assembled based on the Scheimpflug principle. The probe system mainly consists of a diode laser, six collimating lenses, six position sensitive detectors (PSD), a signal processing circuit, and an A/D interface card. Through the specific arrangement of the PSD, four different measurement modules for the developed system are possible, namely the standard triangulation probe module, double triangulation probe module, pentagon-shaped triangulation probe module, and an approximately circular triangulation probe module. Bused on the calculation and filtering of the pentagon-shaped PSD signals, the measurement accuracy was improved. The developed laser probe system was integrated with a coordinate measuring machine, to construct a non-contact measurement system. According to the experimental results, the measurement uncertainty of the developed laser probe system, with respect to different surface roughness and slope, was about 15 microns. Among the four different measurement modules checked, the pentagon-shaped triangulation probe module has the best result.
