The current solutions implanted in the majority of manufacturing systems controlled by PLCs were developed through the language of programming known as ladder. Such a language, easily learned and handled, shows to be efficient whenever the system to be implanted does not demand greater complexity of analyses. Bigger systems, presenting characteristics in which resource compartments, parallelism and synchronizing among processes are more frequent, demand the adoption of solutions differentiation. This article presents a teaching experience and practical application of Petri nets in a Mechatronics Engineering graduation course. Copyright © 2007 IFAC.

This paper discusses the importance of an engineering systems approach to international bioengineering education and how a new educationalresearch program, the MIT-Portugal Program Bioengineering Systems focus area, aims to develop future global bioengineering leaders. The program, comprising both post-graduate advanced studies and doctoral programs, commences in September 2007. Several other international-collaborative educational and research programs—such as the Cambridge-MIT Institute, the Singapore MIT Alliance, and the Socrates/Erasmus “Erasmus Programme”—offer lessons learned in international collaboration. The MPP Bioengineering Systems program differs from these programs in several respects. The unique collaboration in MPP offers an engineering systems approach, a joint degree offered by three Portuguese universities, and collaborative teaching and research efforts between MIT and Portuguese faculty and students.

Engineers create, design and build, bringing solutions to problems and transforming the environment for betterment of life. Engineers are responsible for the development of science and technology once they design tools, systems and instruments that make possible the acquisition of knowledge in a vast amount of fields. Engineering is responsible for the deep transformation of human relations in the first decade of the 21st century, changing also education paradigms as well as business. A new era in working environment has started, which characteristics are peculiar due to new communications, mobility and globalization. These aspects lead to the fact that now it is also important to train engineers with tools that enable them to act in a working environment that demands a very flexible and innovative mind in order to be inserted in and to keep up with the work market. Knowledge in Basic Sciences, Basic Sciences of Engineering and Specifics of Engineering are fundamental for the training of an engineer. However, the insertion in labor market sometimes demands some practice or experience that should also be provided by the engineering schools. Taking this into account, the Engineering Education Research Team of COPEC – Science and Education Research Council has designed and is implementing a program for an engineering school which main goal is to prepare engineers for the future work market...

As part of its national obligations, ONR must ensure US world leadership in those unique technology areas that insure naval superiority. ONR accomplishes this mission through research, recruitment and education, maintaining an adequate base of talent, and sustaining critical infrastructure for research and experimentation. One critical area requiring support by ONR is the "knowledge infrastructure" in Naval Architecture and Marine Engineering. An innovative knowledge infrastructure in NA & ME consists of two main elements: • People who have the knowledge, skills and experience to perform innovative design and engineering applied to in Naval Architecture and Marine Engineering; and • An industry that employs these people and allows this innovative knowledge to be applied in the ships it designs and builds for the Navy. The universities along with industry develop the technology and educate the people who are employed by industry. In turn, the research supported primarily by the government provides direct support for the conduct of research and the education of the future faculty who perform their doctoral research in this discipline. This study examined the current situation in navy related Naval Architecture and Marine Engineering. The need for ONR support in this area is identified and recommendations made to establish long term support that will provide for the introduction of innovative technology in naval ships. The following are documented in this report to establish this need: (1) The uniqueness of "Engineering for the Marine Environment" is explained. Naval Architecture and Marine Engineering...

The Dian Fossey Gorilla Fund International (DFGFI) contacted MIT in September 2006 for technical assistance to analyze the water-supply potential within the Bisate Sector, Musanze District, Rwanda. The present study focuses on designing low-cost household rainwater catchment systems to improve the quantity and quality of water available and therefore achieve higher standards of living for the Bisate village. Given the climatic and geographic characteristics of Bisate, rainwater harvesting represents one of the most appropriate solutions to improve water supply. The designed low-cost household rainwater catchment system consists of an excavated cistern of 6 cubic meters volume, lined with a plastic tarpaulin sheet and covered with a wood and iron lid, and with a hand pump to extract water. The cistern should provide an average of 16 liters/day/person for the entire year for medium-size houses (roof area of 35 m2) and 21.5 liters/day/person for large-size houses (82 m2). The excavated cistern is designed with walls to stop surface runoff from entering into the cistern, and a hard cover and hand pump to extract water and minimize water contamination from faecal bacteria. The implementation of these small-scale rainwater harvesting systems should improve water quality and supply for the families of Bisate Village.; (cont.) Indeed...

peer-reviewed; The hypothesis of this research is that new techniques are required to facilitate software verification on the highly-integrated, but resource constrained, real-time embedded systems; which are widely used in safety-critical applications. Software verification is an essential but expensive undertaking which often consumes as much or more resources than design activities; this is particularly the case in embedded systems that require functional safety. This research explores the existing techniques for software verification on these systems and the verification challenges posed by modern highly-integrated devices. The author then proposes a novel target-level verification approach which addresses some of these challenges. Advances in semiconductor manufacturing processes have fuelled the relentless shrinking of IC design geometries. This has dramatically reduced the area required for each functional block, reduced costs, and allowed more complex circuits to be realised; which has led to the System-on-Chip (SoC) designs which now include multiple processors within a single die. Undoubtedly many benefits result from this increased integration, but one significant drawback is the loss of access to the many signals indicating the internal operational state. Visibility of these signals is essential for many embedded software verification purposes. In parallel with increasing SoC complexity...

The central and state governments of India have been pursuing several reforms in the higher education sector. In engineering education, the government has already embarked on several reforms within the current legislative framework. Given this dynamic momentum, the engineering education sector in India is expected to receive a significant boost over the next few years. It is therefore timely to take stock and review the position of the sector internationally. This study thus aims to provide the Ministry of Human Resource Development (MHRD), the All India Council for Technical Education (AICTE), and relevant stakeholders with key facts, reliable data, and the results of relevant international comparisons to establish a common ground and to help in measuring the performance of the current engineering education system in India. The government also recognizes the importance of lessons that may be learned from the other Brazil, the Russian Federation, India, and China (BRIC) countries, and these countries were therefore selected for the comparison. This report is organized as follows: section one gives introduction; section two briefly discusses the background of both general higher education and engineering education in India. Section three reviews earlier comparative studies on international engineering education. Section four describes the scope of the study. Section five explains the methodology of data collection and identifies the data sources. Section six outlines the analysis of the collected data and the findings. Section seven presents conclusions. The appendixes describe the engineering education systems of the various countries examined in the study...

Attached is a paper as well as a presentation - - Note that this presentation came from this conference: 15th ANNUAL SYSTEMS ENGINEERING CONFERENCE, OCTOBER 22 - 25, 2012, SAN DIEGO, CA More information is here: http://www.dtic.mil/ndia/2012system/; This paper explores the potential benefits and disadvantages associated with providing a course (or part of a course) in complex systems as part of a systems engineering graduate degree program. An overview of systems engineering education programs and a history of SE curricular design provides context for this exploration. Curriculums other than systems engineering that include courses in complexity, nonlinear dynamics, emergence, chaos, decentralized synchronization through stigmergy, scale-free networks and related topics are also examined. The application of these concepts to design problems is assessed, particularly for engineers in the defense domain. Complex systems learning objectives tailored for systems engineers are proposed. Finally, a framework on which to base a trade-off analysis to determine if such topics should be included in an existing or developing graduate degree program is recommended.

Systems engineering is vital for the acquisition of systems for the Department of the Navy (DON). As systems engineering is a relatively young discipline, no professional engineer occupational series exists under which systems engineers can be classified from a human resources perspective. In addition to the lack of an occupational designation, there is no official competency model to form the basis for employee selection and career development. In order for a competency model to be used for employee selection, it must be validated under the Uniform Guidelines for employee selection. Once validated, the model can be used to create systems engineering position descriptions and related career development plans that would be specifically used for systems engineers within the DON and perhaps for DOD. A baseline competency model is the first step in performing a validation process in accordance with the Uniform Guidelines. In order to begin to address this situation, a system engineering competency model was developed to provide a baseline. This model was designed specifically for the DON, though it should also be useable in any organization that employs system engineers. The core of the model is based on the knowledge, skills, and abilities (KSAs) that a systems engineer needs to develop competency in across varying career levels. These KSAs are defined using Bloom’s Taxonomy to describe...

Approved for public release; distribution in unlimited.; The objective of this instructional guide is to help learners gain practice with the proper framing of a problem for analysis, the first and most critical step in systems architecture and design. A Design Reference Mission (DRM) is outlined and populated with example content for a notional Search and Rescue (SAR) mission. The DRM establishes an operational context, description(s) of the environment and situations in which a system of interest is expected to operate, an operational narrative containing enough detail to generate multiple operational scenario variants, a sequence of operational activities and interactions between each system and other systems in its environment, and measures for establishing goals for mission success. The DRM is to be used to derive specific scenarios for use in making design decisions concerning candidate operational and solution architectures aimed at satisfying the mission success requirements.; The Consortium for Robotics and Unmanned Systems Education and Research (CRUSER)

In response to then Security of Defense William Cohen's challenge to revolutionize defense business affairs and to accelerate the delivery of sophisticated defense systems that increase the effectiveness of our forces, the Naval Postgraduate School (NPS) began a journey into the delivery of graduate systems engineering distributed education program. This report focuses on an outreach approach to delivering the content of these programs to Navy laboratories and other facilities rather than having students seek the school as a provider. Given these challenges, unique strategies had to be developed for program development and delivery. This report will concentrate on two graduate systems engineering programs that are delivered by multiple configurations of blended approaches to distance education. The authors have served as program managers for these programs and have gathered lessons learned over eleven-years.

Modern computer technology facilitates development of rich learning environments that can enhance a student's ability to learn; however, none of the existing educational software systems can support the drill-and-practice mode of learning through the use of problem sets in routine engineering design domains. This thesis discusses the design of a computer-based system that benefits the instructor and the students in a design course by automating the creation of problem sets and their solution. The system allows the instructor to specify a set of design procedures as the design concept on which the generated problems should test the student. Each design procedure has a set of applicable conditions and these are formulated into a constraint satisfaction problem. Using the solution to this problem, the system then generates several problem descriptions along with their solution. The software, developed on a distributed component architecture model, is a general framework that could support multiple domains.

Tertiary education, and in particular technical and engineering education, is critical to India's aspirations of strengthening its reputation as a major competitive player in the Global knowledge economy. The system is huge and complex, and there is a consensus that reforms are imperative. Issues of fair access and affordable participation in higher education are critical if India is to empower its people with educational opportunities that allow individual potential to be fulfilled, and allow more Indian graduates opportunities for employment and to compete in an international arena. There are approximately 2,400 technical and engineering institutions across India's 30 states, of which less than 8 percent of public institutions are autonomous. The demand for tertiary education continues. There has been a phenomenal growth in the number of private colleges across India in the last 20 years. Private colleges now deliver 85 percent of all technical and engineering education. The significant changes in supply and demand make it increasingly important to ensure that tertiary education systems and institutions are effectively and efficiently governed and managed to meet the needs of industry and society. As key national changes are imminent...

Online distance education provides students with a wealth of information. When students submit course-related search term queries, the search engine returns the search hits based on keyword and topic match. A student's particular learning style is not taken into consideration. For instance, a visually oriented student may benefit more than others from viewing videos and interacting with simulations. We address this problem by designing and developing a knowledge-based system for the initial assessment of students' learning styles. Each student's membership in a learning style dimension (e.g. visual or verbal) is estimated probabilistically. We reach this probability value by using a sequential Bayesian approach to administer a dynamic questionnaire that aims to attain a desired confidence level estimate with the minimal number of questions. A multi-agent online tutoring system uses this initial learning style model to start suggesting learning material matching the student's style. Each agent is an expert in a learning style dimension and can suggest the learning materials matching the student's style. In addition, these agents closely follow the student's evolving preferences and continuously update the stochastic model based on the student's online activities. When the student searches for course material...

Design-oriented learning requires tools that support creative processes and student-to-student and student-to-faculty interactions. While most present E-Education systems perform as the asynchronous distribution channel for teaching material, they usually offer little support for project based design processes. This research maps out the key learning events in design classes at MIT's Department of Mechanical Engineering, and proposes guidelines for building E-Education systems to support the unique characteristics of design-oriented learning. Two creative learning processes are identified and two independent, yet tightly related, software systems are implemented and evaluated. The first application, the Peer Review and Engineering Process (PREP), is a web system that helps instructors and students conduct and manage peer review evaluation of design concepts. The second is a real time application called InkBoard that leverages the Tablet PC and Ink medium to provide real-time collaborative sketching over TCP/IP networks. A new streaming network protocol for transferring Ink objects is proposed and implemented. A comparative study against other ink-enabled protocols is also presented.; by Hai Ning.; Thesis (Ph.

(cont.) storage, and education. Tests on the SWSs in Peru demonstrated 99.6% E.coli removal and 95% total coliform removal. Only 30% of the SWSs tested contained water at or above the WHO-recommended concentration of free chlorine residual (0.2 mg/L). The author recommends that use of these HWTSs continues and that the program receives increased support. The two HWTSs would be most effective if combined: filtration plus post-chlorination. In order to further distribute these systems in the future, a sustainable funding plan must be created.; A household water treatment program was implemented in southern Peru in 2003 by CEPIS and the country's Ministry of Health. This program involves the use of two household water treatment systems (HWTSs): the Table Filter and the Safe Water System. The author and a team of researchers from MIT traveled to Peru in January 2004 to assess the program and technologies through water quality tests and personal interviews. This research continued in Peru during March 2004 by local chemical engineering graduates of San Augustine National University. The Table Filter is a combination filter, involving a geotextile cloth pre-filter, sand, and two Pozzani ceramic candles from Brazil. Table Filters tested in Peru provided an average 99% E.coli removal...

One of the Civil criteria in ABET TC2K is that programs “apply current knowledge and adapt to emerging applications of technology,” such as, changes in the building codes. Structural design firms also have the expectation that Civil Engineering Technology (CET) graduates should be able to apply current codes to determine structural loads, required for the analysis and design of structures. While most CET programs expose their students to structural analysis and design using instructor or textbook-prescribed loads, few expose students to the detailed calculation of actual structural loads using current codes. Many jurisdictions in the United States, including New York State, have recently adopted the International Building Code (IBC), which contains the latest provisions on structural loads, including wind and seismic loads for buildings. Prior to 2002, in New York State, the building code only required buildings to be designed for wind loads using a very simple tabular method. Seismic loads were not considered. Under that dispensation, it was possible and feasible to integrate the topic of structural loads, dead, live, snow and wind load, into any one of the structural design courses, all-be-it at an elementary level.

Relevância na Pesquisa
Modeling is a hallmark of the practice of engineering. Through centuries, engineers have used models ranging from informal “back of the envelope” scribbles to formal, verifiable mathematical models. Whether circuit models in electrical engineering, heat-transfer models in mechanical engineering, or queuing theory models in industrial engineering, modeling makes it possible to perform rigorous analysis that is the cornerstone of modern engineering. By considering software development as fundamentally an engineering endeavor, RIT’s software engineering program strives to instill a culture of engineering practice by exposing our students to both formal and informal modeling of software systems throughout the entire curriculum. This paper describes how we have placed modeling in most aspects of our curriculum. The paper also details the specific pedagogy that we use in several courses to teach our students how to create, analyze and implement models of software systems.; Originally published by: Springer - http://www.springerlink.com/content/p25mw252t1596133/?p=e46b23192e3b4798a214c60ad78190b8π=0

Students studying Civil Engineering (CE) at the Further Education and Training (FET) colleges spend periods of time in the classroom and workshop as well as in the workplace during experiential learning. The overall purpose of education and training in the college sector is generally understood as preparing students for employability, and difficulties in colleges performing this role are well known. In this article, these difficulties are examined in a novel way. The everyday perspectives of lecturers and supervisors about student learning in their college programmes and their work experience are translated into more theoretical language, using activity theory. A theoretical argument is made, which suggests that different sites of learning create different purposes, and that these different purposes derive from a distinction between knowledge and practice, which in turn has historical roots. The study concludes by suggesting that a new, common object of integrating theory and practice at all the sites would better link the college and workplace education and training systems, and tentatively suggests how this new object could be put into practice.
