This article describes a novel layer manufacturing process for forming a ceramic part with porous multi-channel architecture by laser gelling under low laser energy. The process involves bonding silica powder by gelled silica sol after exposure by a CO2 laser. Lower laser energy density of 0.8 J/mm2 is required to produce ceramic parts by "gelling effect". Therefore, the geometrical deflection and thermal distortion can be reduced after laser scanning. The inner porous structures were supported by ceramic slurries to prevent sagged deflection and to enhance dimensional accuracy due to optimal slurry suspension. The flexural strength of the green specimen was 4.7 MPa, while that of the gelled specimen was 12.5 MPa after heat-treatment at 1200 °C for 1.5 h. The proposed process has potential for fabricating complex interconnected porous ceramics for tissue engineering applications. © 2011 Elsevier Ltd and Techna Group S.r.l. All rights reserved.

Developing an efficient classification method is a challenge task in many research domains, such as neural network (NN) classifiers, statistical classifiers and machine learning. This study focuses on NN classifiers, which are data-driven analytical techniques. This study presents a cerebellar model articulation controller NN (CMAC NN) classifier, which has the advantages of very fast learning, reasonable generalization ability and robust noise resistance. To increase the accuracies of training and generalization, the CMAC NN classifier is designed with multiple-input and multiple-output (MIMO) network topology. The performance of the proposed MIMO CMAC NN classifier is evaluated using PROBEN1 benchmark datasets (such as for diabetes, cancer and glass) taken from the UCI Machine Learning Repository. Numerical results indicate that the proposed CMAC NN classifier is efficient for tested datasets. Moreover, this study compares the experimental results of the CMAC NN classifier with those in the published literature, indicating that the CMAC NN classifier is superior to some published classifiers. Therefore, the CMAC NN classifier can be considered as an analytical tool for solving classification tasks, such as medical decision making. © 2010 Elsevier B.V. All rights reserved. Source

Measuring sustainable production indicators (SPIs) is becoming an important environmental activity due to government directives and increasing awareness among the populous to protect the environment and reduce waste. For printed circuit board manufacturers, measuring SPIs that are dedicated to sustainable activities usually require a multi-criteria structure with driving and dependence power for tracking. Hence, the measures of SPIs are always based on subjective perceptions and interactive relations in nature. A hybrid method for composing a hierarchical structure based on linguistic preferences and that concurrently applies perception judgment is lacking. This study proposes a novel approach in which fuzzy set theory and interpretive structural modeling are adopted to address the analytical objective. The proposed criteria are categorized into a hierarchical structure and arranged into visual quadrants on a graph according to their driving and dependence powers. The insights graph and hierarchical structure could assist mangers in strategic planning related to improving their firms' environmental activities. Managerial implications and concluding remarks are addressed. © 2010 Elsevier Ltd. All rights reserved. Source

Green supply chain management (GSCM) has become a proactive approach to enhance environmental performance. Under stakeholder pressures and regulations, firms need to enhance GSCM practice, which are influenced by practices such as green purchasing, green design, product recovery, and collaboration with customers and suppliers. As proactive firms adopt GSCM, their economic performance and environmental performance will be improved. Hence, this study aims to examine the influential factors among eight criteria of three main GSCM practices, namely practices, performances, and external pressures. To deal with the vagueness of human being's perceptions, this study utilizes the fuzzy set theory and decision making trial and evaluation laboratory method to form a structural model to find out the cause and effect relationships among criteria. The results and managerial implications are discussed. © 2010 Elsevier Ltd. All rights reserved. Source

This paper presents an intelligent traffic management expert system with RFID technology. The system provides both practically important traffic data collection and control information and can trace criminal or illegal vehicles such as stolen cars or vehicles that evade tickets, tolls or vehicle taxes. The system architecture consists of an RFID reader, a passive tag, a personal computer, a pair of infrared sensors, and a high-speed server with a database system. Based on RFID technology, the system collects and calculates average speed and average flow information on each road of a district area in a city. It then transmits the messages from all the congested roads in a district area to the server in the district center via a communication program. Through a flooding algorithm, each server in a district center exchanges and updates information with all neighbor servers in other district centers so all that the servers in various district centers can get all the latest congestion messages in a city. Therefore, a dynamic navigation system can find the shortest path that avoids congested roads. Meanwhile, we compare three types of tags for choosing a better solution for e-plates in the future. We also adopt infrared sensors for detecting cars that do not have a tag. © 2009 Elsevier Ltd. All rights reserved. Source
