A systems approach to computer-based training
No full textThis paper describes the hardware and software systems approach used in the Automated Recertification Training System (ARTS), a Phase 2 Small Business Innovation Research (SBIR) project for NASA Kennedy Space Center (KSC). The goal of this project is to optimize recertification training of technicians who process the Space Shuttle before launch by providing computer-based training courseware. The objectives of ARTS are to implement more effective CBT applications identified through a need assessment process and to provide an ehanced courseware production system. The system's capabilities are demonstrated by using five different pilot applications to convert existing classroom courses into interactive courseware. When the system is fully implemented at NASA/KSC, trainee job performance will improve and the cost of courseware development will be lower. Commercialization of the technology developed as part of this SBIR project is planned for Phase 3. Anticipated spin-off products include custom courseware for technical skills training and courseware production software for use by corporate training organizations of aerospace and other industrial companies

An online fabric database to link fabric drape and end-use properties
No full textThe main obstacle for adaptation of fabric selection through the Internet is that there is no objective selection method that is suitable for fashion fabrics. The purpose of this research is to develop an objective evaluation method for selecting fabrics through an online fabric database. The relationship between fabric mechanical properties and fabric drape was investigated. One hundred eighty-five commercial fabrics from different manufacturers were tested using the Kawabata fabric evaluation system (KES-FB) and Cusick drape tester. Applying regression analysis, the parameters that were significantly correlated with drape coefficient (DC) were determined. The test results, fabric structural parameters, and contact information for fabric manufacturers, were included in the database. A web-site with a user interface allowing users to implement various types of searches was published on the Internet. Fuzzy linear clustering technique was used to predict fabric drape property. The accuracy for predicting fabric drape using this technique was 94%. This means the model using fuzzy linear clustering is an efficient method to predict fabric end-use properties. Additionally, a new method to measure drape coefficient using Photo Shop was developed by this author. Instead of weighing paper rings, shaded drape area was used to calculate the drape coefficient. With the new Photo Shop method, the cost, testing time and human error was reduced while the accuracy of the test result was increased

[[alternative]]Textual vs. Iconic Programming Languages: An Investigation of Students’ Learning Effects
No full text[[abstract]]In this research we investigated if the use of textual or iconic programming languages would result in different learning effects. Fifty-two six graders from a local elementary school participated in this research. A class of 26 students learned to program in MSWLogo and the other class of 26 students learned Drape. Both MSWLogo and Drape are Logo-style languages; however, programmers use textual commands to program in MSWLogo while iconic commands are used in Drape.
The quantitative data collected in this research included grades of five paper-based tests and a hands-on programming test. Each paper-based test included questions assessing such cognitive abilities as knowledge, comprehension, application and analysis. The programming test consisted of 24 problems: 16 of them required students to write complete programs while the remaining eight problems were for students to modify existing programs. Analyses of test grades revealed that students of the MSWLogo group performed significantly better than those of the Drape group in the first three paper-based tests. However, there was no significant difference between the two groups in the last two tests. It seems that there is a steeper learning curve for students to program in Drape (iconic language) than in MSWLogo (textual language). Nevertheless, when students become more and more familiar with language syntax, the difference diminishes. The hands-on programming test did not show a significant difference between performances of the two groups, whether with write-complete-program problems or with modify-program problems.
The qualitative data collected in this research included automatically captured screen logs of students’ programming processes while they were working on the programming test, results of a questionnaire survey conducted at the end of the experiment, and journals kept by students and the instructor. A qualitative analysis of these data indicated that students of the MSWLogo group made syntactic errors frequently while students of the Drape group were often confused by icons that were not intuitively clear or those icons that looked similar to each other. Apparently, each language has its own disadvantages in usability. With regard to students’ attitudes toward programming, there were no significant differences between the two groups in how much students liked programming or if they would like to learn to program again in the future.
To sum up: This research concludes that there are no differences between the two groups of six graders who learned MSWLogo (textual language) and Drape (iconic language) respectively, whether in students’ performance or their attitudes toward programming. Many people may tend to think that iconic languages are easier to learn and would be preferred by elementary school students. Our findings may help to shed such a delusion and provide some useful hints to primary school teachers when it comes to select a suitable programming language for their students to learn.
Hot forming of composite prepreg: Numerical analyses
No full textInternational audienceThe work presented here is part of the ``FORBANS'' project about the Hot Drape Forming (HDF) process consisting of unidirectional prepregs laminates. To ensure a fine comprehension of this process a combination strategy between experiment and numerical analysis is adopted. This paper is focused on the numerical analysis using the finite element method (FEM) with a hyperelastic constitutive law. Each prepreg layer is modelled by shell elements. These elements consider the tension, in-plane shear and bending behaviour of the ply at different temperatures. The contact/friction during the forming process is taken into account using forward increment Lagrange multipliers
PS Geologic Modeling and History Matching of Multi-Scale Flow Barriers in Deep-Water Reservoirs: Methodology and Field Application*
No full textThis work addresses the situation where multi-scale shale drapes are present along channel, channel belt and/or valley bounding surfaces, but the channel locations are uncertain or unknown. In order to reduce the uncertainty of shale drape location, first a realistic representation of the channel distribution must be obtained and constrained to hard data; then the channel and drape locations must be calibrated to the production data. We propose a coupled geologic modeling and history matching method where the channelized reservoir architecture is simulated with a pre-defined stacking pattern using surface-based modeling techniques. Then the discontinuous shale drapes along multi-scale bounding surfaces are simulated using multiple-point statistical techniques. Channel geometry, location and the corresponding shale drape locations are gradually perturbed until the corresponding flow responses match the field production data. The perturbation during the history matching honors the individual channel geometry statistics and the interpreted channel stacking patterns, providing a geologically consistent perturbation. A 3D geologic model based on a real turbidite reservoir in offshore West Africa is used to demonstrate this modeling and history matching approach.
