The experience and benefits associated with hands on experience using real hardware components as compared to virtual analysis using computer simulation tools are invaluable. In this paper, we present the development and use of an educational environment for experimentation and reinforcement of concepts found in dynamic system modeling and real-time controls in upper level undergraduate and graduate courses in engineering. This environment requires two computers, a host and a target that communicate through a serial protocol. The basic software tools (reside on the host) are the ubiquitous MATLAB along with Simulink, Real Time Workshop, xPC Target, and Visual C++ compiler. The hardware in the loop, HIL, device to be modeled and controlled is a custom developed magnetic levitation system that is nonlinear, open loop uns table and has time varying dynamics. A compatible data acquisition board (resides in the target) is required to provide the interface between the software and the device to be controlled. This environment provides for the development of various controllers and allows for direct comparison of their performance with hardware in the loop as shown in the presented examples.","PeriodicalId":355306,"journal":{"name":"2003 GSW Proceedings","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116348765","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During exploration, seismic images of the earth’s shallow subsurface are scrutinized by interpreters, whose prerogative is to search for patterns indicating possible hyrdrocarbon reservoirs. One of the most striking features of these seismic signals is their highly non-stationary character, making such interpretations time-sensitive. Raw data sets need to be processed for time and depth corrections, posing some of the most challenging aspects of signal processing techniques, making use of relevant algorithms to eventually help extract the maximum possible information of the subsurface earth from each such data set. However, the tools for information extraction used until recently did not take into account the fundamental non-stationary character of seismic data, and the quality of information extraction suffered as a result. However, at present, high-resolution time-frequency representation technique provides a natural domain for analyzing and processing such non-stationary data. This technique can measure the local changes in frequency and scale content of a signal in the data set. In this paper we present the applications of this advanced signal processing and analysis technique to solve problems related to geophysical seismic data especially applicable to hydrocarbon exploration and prospecting. One of the latest digital signal processing tools is MATLAB (Matrix Laboratory), from MathCAD, which can be used to analyze, interpret, and process seismic data to specialized graphics features required in engineering and scientific practices. With the latest trends in research turning interdisciplinary, MATLAB acts as a perfect example to bridge between the domains of electrical engineering and geosciences.","PeriodicalId":355306,"journal":{"name":"2003 GSW Proceedings","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131833122","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The spatial and temporal distribution of concentration in two-phase flow not only creates obstacles in detecting, measuring and description of flow patterns, but also creates even more difficulties in comparing the results achieved from different measurement systems, which creates the need for comparative studies by using four different measurement systems, i.e., capacitive, conductive, pressure and optical methods to measure characteristic parameters for controlled experimental conditions. The study deals with two-phase flow of air-water mixture in a small horizontal square. In this experiment, air and water are passed through a mixing chamber placed at the start of the square channel. The sensors are placed non-intrusively along the channel to measure the concentration of the two phases and the Computer Aided Experimentation Station (CAES) is used to generate a wide range of flow conditions and flow patters in the horizontal adiabatic flow, where the in-situ concentration, film thickness, and pressure are measured simultaneously in the same time and space for air-water mixture flow. The data were converted to averaged values, from which root mean square (RMS), histograms and power spectrum density plots were plotted. The analyses of the measured and plotted results will be compared and presented in this paper.","PeriodicalId":355306,"journal":{"name":"2003 GSW Proceedings","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130606237","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Convergent technologies involve computer based hardware and software, wireless networking, multimedia, hypermedia, Internet, virtual reality, interactive TV (iTV), digital TV (DTV), satellite and advanced classroom gadgetry. Convergent content combines conventional books, lecture notes, and video with digitally based information on CD’s and DVD’s, on-line laboratory experiments and demonstrations both locally and globally via the internet, internet based information resources, classroom recording of ideas from convergent and divergent thinking, discussions and group activities using visual, audio and text authoring software. The convergent classroom is allowing the same and new content to be presented via multiple ways on different platforms and to be saved for future use in digital asset banks and warehouses using multiple means of storage and use. Convergent best practice pedagogy is optimized in the convergent classroom to allow problem-based learning, objective based learning, cooperative learning, project based learning, accelerated learning, visual learning, constructivism and Socratic learning. The classroom is designed to optimize the five basic types of thinking: cognitive, memorative, convergent, divergent and evaluative - to produce the creativity and idea generative capacity often missing from conventional classrooms.
