Functional Dependency Network Analysis (FDNA) is a methodology that identifies whether the level of operability risks in a portfolio of engineering programs are acceptable and allows management to better allocate resources to programs that face high risk and are most critical to the operational capabilities of the portfolio. The scope of this paper is the methodological development of FDNA, discussion of peculiar characteristics of research and development (R&D) programs and why FDNA is especially suitable to governing R&D portfolios towards assessing risk of mission failure, and a proof-of-concept application.. The result shows how FDNA may complement the practice of governing R&D by highlighting the higher level objectives and mission of the portfolio, using the notion of capabilities to model time-phased delivery of R&D outputs, as well as emphasis on program risks for better resource allocation.

The Missouri University of Science and Technology (Missouri S&T) offers more than 65 degree programs in engineering, science, computing and technology, business, management systems, the humanities and the liberal arts. Students interested in graduate study may pursue their interest either through graduate certificate programs or through full-fledged Masters and PhD degree programs. In the last five years, non-degree graduate certificates have become increasingly popular. This has raised questions about the value of graduate certificate program from the perspective of the student, the university and industry. Do certificate programs provide real world skills and knowledge valuable to industry? Do they serve as effective recruiting tools for the university? Do they provide opportunities for students to meet their professional goals in terms of salary increase, promotions, and the like? This research is specifically aimed at answering these questions. Surveys were developed that assess perceptions of value of graduate certificates to key stakeholders (students, university, and industry). The focus of this paper is from the perspective of current graduate certificate students of the engineering management and systems engineering department of Missouri S&T. Results provide guidance to engineering managers, engineering educators, and engineering professionals of the value added to workforce by engineering graduate certificate programs.

The development of a chopstick-like two-fingered micromanipulator based on a hybrid mechanism is presented. The microhand consists of two 3-prismatic-revolute-spherical (PRS) parallel modules connected serially in a mirror image style. Each module has a long glass pipette as an end effector. The development process consists of three phases. In the first phase, analysis and mathematical modeling, a novel solution of the inverse kinematics problem (IKP) of a 3-revolute-prismatic-spherical (RPS) parallel module, is derived and applied with proper modification to the case of 3-PRS of the proposed mechanism. The solution is extended to the two-fingered hybrid mechanism of the microhand. In the optimization and design phase, the optimization of the chosen design parameters of a theoretical 3-PRS parallel module is carried out using two approaches: discretization method and genetic algorithms. Based on the optimal design parameters, a CAD model of the 3-PRS finger module is built, and a complementary optimization step using the ANSYS Workbench program is carried out to determine suitable characteristics of the pin flexure hinge. Finally, the total CAD model of the two-fingered hand is built. In the realization and implementation phase, the description of the hardware system of the two-fingered microhand prototype is presented. The program description, calibration method, practical Jacobian matrices, practical workspace, and error analysis of the prototype are discussed. © 2009 IEEE.

Based on the improved supply chain operations reference (SCOR) model, a network-topology structure of cycle quality chain operations reference (CQCOR) model is built up, which realizes the cycle operation by an added quality process of reverse manufacturing. The concept of cycle quality chain management is defined, and its cost structure is analyzed according to positive and reverse quality processes. If the quality level is controlled by the positive quality cost, then the reverse quality cost is a nonlinear function of quality level. All the quality processes are connected by acceptable probability, so the optimized objective function is described as a fuzzy multi-objective function comprising maximum of the total profit of quality chain, maximum of the recycling efficiency and maximum of environment protection and source saving. The effects of different quality policies on fuzzy rules are compared by a simplified example. When the policy of recycling efficiency dominates, the total quality profit will be less than that of maximum profit policy.

There have been attempts to examine technological structure and linkage as technological impact. Cross-impact analysis (CIA) has been mainly employed with cross-impact index to identify core technologies. Cross-impact index, however, cannot successfully capture the overall relationship based on the impacts among technologies. Furthermore, it is a time-consuming task to calculate all cross-impact index especially based on patents without developing computer program. To address this limitation, this study suggests new approach to identify core technologies in technological cross-impact interrelationship. Specially, the approach applied data mining technique and multi-criteria decision making (MCDM) method to the co-classification information of registered patents. At first, technological cross-impact matrix is constructed with the confidence values by applying association rule mining (ARM) to the co-classification information of patents. Then, Analytic Hierarchical Process (ANP), one of MCDM methods, is employed to the constructed matrix for identifying core technologies from the perspectives of overall cross-impacts. A case study of telecommunication technology is conducted to illustrate the process of executing and utilizing the proposed approach. It is expected that suggested approach could help technology planners to formulate strategy and policy for technological innovation.

The engineering management (EM) undergraduate degree program at Missouri University of Science & Technology (formerly University of Missouri-Rolla) was the first program of its kind. The program started over 40 years ago and it is one of only five ABET accredited undergraduate EM programs [1]. The initial degree program included a senior year of management courses in conjunction with three years of courses in common engineering disciplines such as mechanical, electrical, and civil engineering. In the 1990s the program underwent a major restructure and students combined core engineering management classes with an emphasis area inside the department. Industrial, manufacturing, packaging, and quality engineering emphasis were added as well as management of technology, while maintaining the ability to pursue traditional engineering emphasis areas. Recently major changes were made to extend the set of core courses and to streamline the technical emphasis areas. The need for these changes was clear, but attempts to make changes in the past have proven difficult. The new, more stringent ABET accreditation criteria [2], specifically those which relate to Educational Objectives, program Outcomes, Continuous Improvement, and Curriculum provided the needed impetus and assistance to make significant changes to the undergraduate curriculum. This paper describes the processes which were used to make the changes, and how the ABET criteria influenced these processes. In addition, we also discuss the hurdles and challenges faced as the process moved forward, ultimately leading to the revised curriculum. The paper concludes with specific recommendations for revising undergraduate curriculum in light of the current ABET guidelines. © American Society for engineering Education, 2009.

We propose the representative slice method. This method is a parameter adjustment technique for viscous fluid registration. We experiment a whole-body CT image and whole-body MRA image registration using this method. The representative slice method is mainly consisted in three steps. In the first step, we divide whole-body image into six segments (head, chest, abdomen, hips, legs, and feet). In the second step, we select representative slices from six segments. In the last step, we regulate the viscosity for viscous fluid registration from 13 values of the viscosity. The selective viscosity is provided the well alignment in each segment's slices. In this way, the parameter regulation is performed for only the representative slices. Using this method, we can save a lot of time to regulate the viscosity and other parameters in whole-body image registration. After whole-body registration, we find some misregistered area. So we define these areas as new segments, and regulate the viscosity using the representative slice method. As a result, only 109 in 1,687 slices cannot be aligned. Thus we can register almost all whole-body CT image and MRA image, and the same time, we can also register two three-dimensional human atlas images using same displacement. Copyright 2009 ACM.

Recently, failure detection by acoustic data is applied to quality check such as new or used bill classification. However, it is difficult to reduce the noise in acoustic data of bill by conventional techniques since there are many types of noises in the environment. In this paper, we propose a method by using an adaptive digital filter and a neural network to reduce noises in acoustic data of bill. First, the acoustic data is divided into some frequency bands by the wavelet transform. Next, each data is passed through two types of filters to reduce the noise. One is an adaptive digital filter trained by the LMS algorithm, and the other is a nonlinear filter based on a neural network trained by the error back-propagation method. Then the processed data in each frequency band are composed to get an estimated signal. Finally, simulation results are illustrated to show the effectiveness of the proposed method compared with conventional approaches. © 2009 The Institute of Electrical Engineers of Japan.

Different learners have different needs;they differ, for example, in their learning goals, their prior knowledge, their learning styles, and their cognitive abilities. Adaptive web-based educational systems aim to cater individual learners by customizing courses to suit their needs. In this paper, we investigate the benefits of incorporating learning styles and cognitive traits in web-based educational systems. Adaptivity aspects based on cognitive traits and learning styles enrich each other, enabling systems to provide learners with courses which fit their needs more accurately. Furthermore, consideration of learning styles and cognitive traits can contribute to more accurate student modelling. In this paper, the relationship between learning styles, in particular the Felder-Silverman learning style model (FSLSM), and working memory capacity, a cognitive trait, is investigated. For adaptive educational systems that consider either only learning styles or only cognitive traits, the additional information can be used to provide more holistic adaptivity. For systems that already incorporate both learning styles and cognitive traits, the relationship can be used to improve the detection process of both by including the additional information of learning style into the detection process of cognitive traits and vice versa. This leads to a more reliable student model. © 2009 Elsevier Ltd. All rights reserved.

In recent years, due to the emergence of P2P technology, people rely on the Internet to share resources. It is believed that the number of users and shared resources will become enormously huge. As a result, many researches have been dedicated to improve the scalability and efficiency of P2P models. In this paper, we propose a multi-layered P2P resource sharing model, called ML-Chord, that assigns nodes into Chord-like layers based on the categories of shared resources. From the experimental results, it shows that ML-Chord is both efficient and scalable. © 2008 Elsevier Ltd. All rights reserved.
