Designing a systems engineering curriculum is a complex process, not in the least because it involves a variety of academic professionals whose perceptions and interests rarely concur from the onset. The variety in stakeholders breeds variety not only in values and objectives, but also in supposed, and mostly tacit views of an educational system. In such an ambiguous design context, models serve to make knowledge explicit and facilitate communication. The paper contains a description of curriculum design in systems engineering, policy analysis, and management (SEPA) at Delft University of Technology (DUT), with a particular emphasis on these models, and the way they are embedded in a systems approach to curriculum design View full abstract»
Ecole Centrale de Lille (EC Lille: a French “grande ecole” or “graduate engineering school”) trains engineers who follow a wide variety of scientific and technical courses. First, the students have to pass a highly competitive entrance exam, after two years of preparatory classes. They then spend three years in the school, training to become multidisciplinary engineers. An important component of the curriculum is based on a Project-Activity: on his arrival, the student undertakes a team project to which he will devote at least 300 hours during the first two years. The paper situates the Project-Activity in its context, specifies the goal that it represents in the training of students, and develops the system of monitoring set up in order to increase the success of such an activity View full abstract»

Gesture based applications widely range from replacing the traditional mouse as a position device to virtual reality and communication with the deaf. The article presents a fuzzy rule based approach to spatio-temporal hand gesture recognition. This approach employs a powerful method based on hyperrectangutar composite neural networks (HRCNNs) for selecting templates. Templates for each hand shape are represented in the form of crisp IF-THEN rules that are extracted from the values of synaptic weights of the corresponding trained HRCNNs. Each crisp IF-THEN rule is then fuzzified by employing a special membership function in order to represent the degree to which a pattern is similar to the corresponding antecedent part. When an unknown gesture is to be classified, each sample of the unknown gesture is tested by each fuzzy rule. The accumulated similarity associated with all samples of the input is computed for each hand gesture in the vocabulary, and the unknown gesture is classified as the gesture yielding the highest accumulative similarity. Based on the method we can implement a small-sized dynamic hand gesture recognition system. Two databases which consisted of 90 spatio-temporal hand gestures are utilized for verifying its performance. An encouraging experimental result confirms the effectiveness of the proposed method View full abstract»

Engineering education is beset by many of the same challenges that have affected American industry. Much has been recommended and implemented to improve engineering education. However, the traditional structure of engineering education remains, even though current exigencies require a fundamental restructuring. In an earlier paper, the author proposed a para/professional model as an alternative to the traditional engineering degree structure (J.M. Tien, 1999). At a more detailed level, the paper proposes to restructure the very nature of how higher education is delivered: from a group-centered activity to an individual-centered approach that would allow any one to access educational material or multimedia courseware at any time and from any where. Fortunately, the enabling technologies for such an individual-centered approach are, for the most, available. Nevertheless, several challenges must be addressed before individual-centered education can become a reality View full abstract»

Little work has previously been reported on the use of fuzzy logic within statistical process control when this is used for fault detection as part of quality control systems in industrial manufacturing processes. Therefore, the paper investigates the potential use of fuzzy logic to enhance the performance of statistical process control (SPC). The cumulative sum of the deviation in the monitored parameter is combined with the deviation in an attempt to discriminate between false alarms and real faults and, consequently, to improve the quality of the solution. Combinations of control rules are utilized and trained to cope with different inputs such that rejection of false alarms is achieved and quick detection of real faults is obtained. The design and implementation of this fuzzy expert system (FES) are presented, and a comparative rule based study is performed View full abstract»
In 1992, Delft University of Technology (DUT) established a new Master degree program in the field of systems engineering, policy analysis, and management. This educational program is administered by the School of Systems Engineering, Policy Analysis, and Management (SEPA). The SEPA administration aims for high quality of all aspects of its educational program. A quality management system was put in place when classes started in 1992. This system consists of protocols and is administered by an educational advisor. The system is stake-holder-centered rather than based on didactic principles. The objectives of the system are to secure external and internal consistency of all elements of the educational program. Through a variety of assessment methods, information is collected from students, faculty, and experts from outside the university on the quality of curriculum design, teaching methods, teaching skills, and the learning environment. Assessment methods vary for the various stakeholder groups; the frequency of assessment depends on the frequency with which classes are taught and adjusted, and on the frequency of external reviews. Assessment criteria are derived from stakeholder objectives. Reports are used successfully for problem detection, diagnosis, and remediation. The system characteristics, strengths and weaknesses, may be explained in part by the fact that the system was developed to meet the needs of the SEPA administration. The set of assessment criteria and the importance of the different assessment methods would change if the system was administered by an other stakeholder in SEPA education View full abstract»

Development of skilled robotics draws clues from model based theories of human motor control. Thus, a comprehensive anthropomorphic background is given. Skills in robotics are viewed as a tool for fast and efficient real time control that can handle complexity and nonlinearity of robots, generally aiming at robot autonomy. In particular, a skill of redundancy resolution is addressed through a skill representation problem based on Function Approximator. The task of the robot is approximated by a set of parameterized motion primitives. Adopted parameters are also parameters of the function approximator, i.e., skill used. Redundancy is resolved during skill learning based on available expert knowledge, yielding parameterized joint motions. The approximation procedure (Successive Approximations), a major contribution of the paper, is used for batch compilation of parameterized examples, resulting in a parameterized skill model. Such skill enables a user, inexpert in redundancy resolution, to gain benefits from redundant robots. All properties of the Successive Approximations procedure such as accuracy in interpolation and extrapolation, acceleration in redundancy resolution and upgrading to new skill regarding the task variation, are discussed in the example of a five degrees-of-freedom planar redundant robot, performing parameterized ellipse as motion primitive View full abstract»

In the traditional process of product design, a sequential approach treats each of the design steps individually without considering requirements of manufacturing, assembly and other downstream activities in the product life cycle. The lack of systematic and simultaneous consideration on the impact of design decisions on manufacturing and assembly leads to repeated and excessive changes in design and processes. To resolve this problem, the concurrent engineering approach to product design foresees and avoids potential design flaws by incorporating design requirements from downstream activities of the product development life cycle early in the design stage. This research develops a methodological framework for product life cycle design in concurrent engineering. Through a cohesive organization of semantics of high-level design features and relationships, this representation provides a means to evaluate the impact of design on subsequent activities in the product life cycle, including design for manufacture (DFM), design for assembly (DFA), and design for productivity (DFP). In the first stage of a two-level design, selection of design candidates is made based on multiple design criteria using utility theory taking into account imprecision of design information and user preference. The second stage of design further fine-tunes attribute values of the selected design by a genetic algorithm based parametric optimization procedure. An illustrative example of two alternative designs of a milling fixture demonstrates the effectiveness of the framework and its implementation methodology View full abstract»

Systems engineering education is analyzed. The root of systems engineering is system theory, and both are given a brief overview. The methodology of systems engineering is used to design an educational concept. Four alternative approaches, and their merits are tested and evaluated against the requirements defined for education. The conclusion, for the benefit both of engineering education in general and systems engineering in particular, is an integration of systems engineering principles into the education of all branches of engineering, rooted as they are in system theory and design practice already. This approach means a rationalization of the present engineering education, and meets the requirements from industry to a wider spread use of systems engineering principles and practices View full abstract»

Given the length of time systems engineering has been taught in the US, it is now appropriate to examine the types of programs being offered and to compare and contrast these programs. The paper provides this comparison with a view toward the future of systems engineering education in the US. In particular, we first examine the US undergraduate and graduate programs in systems engineering in order to understand what is taught and how it is taught. Using cluster analysis, we identify four distinct types of systems engineering undergraduate programs, and an informal analysis examines the directions in the systems engineering graduate programs. Next we look at issues in systems engineering education, which have shaped the development of the curricula over the last thirty years. These include the definition of systems engineering, associated professional societies, similar degree types, the role of an undergraduate systems engineering degree, and the role of information technology in systems engineering. We conclude with opportunities for systems engineering education within the US with regard to curricula directions and job opportunities View full abstract»
Exploratory analysis of factors influencing performance dynamics of telecommuters and traditional office workersPublication Year: 2000 , Page(s): 239 - 251
Advances in information technology are enabling the formation of new work arrangements, where employees may perform work activities at any location, at any time. This includes remote locations such as an employee's home or a satellite office. When employees work remotely, there are fewer opportunities for face-to-face (FTF) communication, and more communication occurs in non-FTF modes. Communication is a crucial component of the work process and can affect the performance of work activities. Clearly, the resources necessary to provide an effective work environment are different for traditional and remote workers. It is thus critical to identify and study the dynamics of this environment to foster effective job performance. The authors are particularly interested in the use of communication to coordinate work activities and the resulting effect on performance. We investigate the difference in use of formal, informal, and electronic coordination techniques in the remote and traditional work environments. We also investigate the influence of job characteristics and information technology (IT) factors on job performance in both work environments. The study was conducted through a survey of a large number of telecommuters and a control group of nontelecommuters in eight firms in Atlanta (USA). We use inductive learning to identify patterns of behavior present in the data. Results from the study indicate communication needs in this work environment are much more complex than previously recognized. The research indicates that the method of use of communication channels and the communication partner must be considered, in addition to the work environment of the individual to provide an atmosphere conducive to good performance. We also found that job characteristics and IT factors had differing effects on the groups which should be explored further View full abstract»

The authors develop a parallel structure for the time-delay neural network used in some speech recognition applications. The effectiveness of the design is illustrated by: (1) extracting a window computing model from the time-delay neural systems; (2) building its pipelined architecture with parallel or serial processing stages; and (3) applying this parallel window computing to some typical speech recognition systems. An analysis of the complexity of the proposed design shows a greatly reduced complexity while maintaining a high throughput rate View full abstract»
