TELEPHONE AREA CODE CHANGED Please note that COSMIC's telephone area code is now 706. 1992 NASTRAN COSMIC announces the 1992 release of NASTRAN, the NASA Structural Analysis System. This powerful general-purpose finite element analysis program provides the engineer with inexpensive source code for a wide range of modeling and analysis tasks. NASTRAN permits the effects of control systems, aerodynamic transfer functions, and other non-structural features to be incorporated into the solution of structural problems. The system handles such special cases as buckling, transient response, aeroelastics, and magnetostatics as well as most standard FEA problems. The 1992 NASTRAN release incorporates a number of cost and CPU time-saving improvements. The executable has been made 70% smaller for RISC-based Unix machines by linking NASTRAN into a single program, freeing 33 Mb of system disk space for handling larger problems. The fast eigensolution extraction routine and a number of basic matrix operations have been made more efficient by including new methods, new logic, new I/O techniques, and new subroutines. The Modified Givens Method has been incorporated, and 3 new elements for modeling pressure-stiffened structures were added. The new on-line Help feature can search, display, and print selected sections of the User's Manual. COSMIC supports 4 computer platforms: IBM (370 architecture), CDC, DEC VAX/VMS, and DEC RISC/ULTRIX. The IBM version has additional files that provide significant performance improvement on the 3090 vector architecture. First-year multi-user source code license, $7,000. Single workstation executable license, $2,000. Call us, and we can FAX a license agreement for your review. CRACK GROWTH Predictions of fatigue crack growth behavior can be made with the Fatigue Crack Growth Structural Analysis (FASTRAN II) computer program from NASA Langley Research Center. As cyclic loads are applied to a selected crack configuration with an initial crack size, FASTRAN II predicts crack growth as a function of cyclic load history until either a desired crack size is reached or failure occurs. FASTRAN II is based on plasticity-induced crack- closure behavior of cracks in metallic materials and accounts for load-interaction effects, such as retardation and acceleration, under variable-amplitude loading. The closure model is based on the Dugdale model with modifications to allow plastically deformed material to be left along the crack surfaces as the crack grows. Plane stress and plane strain conditions, as well as conditions between these two, can be simulated in FASTRAN II by using a constraint factor on tensile yielding at the crack front to approximately account for three-dimensional stress states. FASTRAN II contains seventeen predefined crack configurations (standard laboratory fatigue crack growth rate specimens and many common crack configurations found in structures); and the user can define one additional crack configuration. FASTRAN II is written in standard FORTRAN 77. It has been successfully compiled and implemented on Sun4 series computers running SunOS and on IBM PC compatibles running MS-DOS using the Lahey F77L FORTRAN compiler. Sample input and output data are included with the FASTRAN II package. The UNIX version requires 660K of RAM for execution. The standard distribution medium for the UNIX version (LAR-14865) is a .25 inch streaming magnetic tape cartridge in UNIX tar format. It is also available on a 3.5 inch diskette in UNIX tar format. The standard distribution medium for the MS-DOS version (LAR-14944) is a 5.25 inch 360K MS- DOS format diskette. The contents of the diskette are compressed using the PKWARE archiving tools. The utility to unarchive the files, PKUNZIP.EXE, is included. Program $1,000; documentation $26. FILE INTERCHANGE TOAD, Transferable Output ASCII Data (LAR-13755), is a system designed at NASA Langley Research Center to facilitate the transfer of data across communication networks and dissimilar host computer systems. Any data file conforming to the TOAD format standard is called a TOAD file. The TOAD Gateway is an interactive software tool for converting TOAD files to and from a variety of other file formats. It currently reads and writes the following file formats: TOAD; Standard Interface File (SIF); Program to Optimize Simulated Trajectories (POST) input; Comma Separated Value and Tab Separated Value, common in PC and Macintosh spreadsheet and database packages; and a general free format. Additional modules for accommodating other formats are easily developed and installed. The TOAD Gateway asks the user a few questions and accepts a variety of English answers, giving the new or occasional user an understandable and convenient tool for basic data management. Upon opening an incoming data file, the Gateway automatically determines its format and "plugs in" the appropriate interpreter. This feature is particularly beneficial when working with a data file with an unknown format. The TOAD Gateway, LAR-14484, is written in FORTRAN 77 for interactive execution on CONVEX C series, Sun3 and Sun4 series, Silicon Graphics 4D and Personal IRIS series, and DEC ULTRIX and VAX/VMS series workstations, all with little or no modification. TOAD Gateway requires 0.5Mb of RAM for execution, though increasing the Gateway's capacities will require additional memory. The standard distribution medium for the TOAD Gateway is a .25 inch streaming magnetic tape cartridge in UNIX tar format. It is also available in DEC VAX BACKUP format on either a 9-track 1600 BPI magnetic tape or a TK50 tape cartridge. Program $650; documentation $13. FILE INTERCHANGE The TOAD Editor is an interactive software tool for manipulating the contents of TOAD files. Selected subsets of data may be tabulated, sorted, exchanged, duplicated, filtered, removed, replaced, inserted, and transferred to and from other TOAD files. It is commonly used to extract filtered data subsets for results visualization. The TOAD Editor also offers a number of user- oriented features such as on-line help, clear English error messages, a start-up file, user-defined macros, a command history, user variables, an UNDO feature, and a full compliment of mathematical, statistical, and conversion functions. A companion program, the TOAD Gateway (LAR-14484), converts TOAD files to and from a variety of other file formats. The TOAD Editor is written in FORTRAN 77 for interactive execution on CONVEX C series, Sun3 and Sun4 series, Silicon Graphics 4D and Personal IRIS series, and DEC ULTRIX and VAX/VMS series workstations, all with little or no modification. TOAD Editor requires 2.5Mb of RAM for execution, though increasing the Editor's capacities will require additional memory. The standard distribution medium for the TOAD Editor is a .25 inch streaming magnetic tape cartridge in UNIX tar format. It is also available in DEC VAX BACKUP format on either a 9-track 1600 BPI magnetic tape or a TK50 tape cartridge. Program $1,000; documentation $32. HUMAN PERFORMANCE MAT, a Multi-Attribute Task battery from NASA Langley Research Center, gives the researcher the capability of performing multi- task workload and performance experiments. The battery provides a benchmark set of tasks for use in a wide range of laboratory studies of operator performance and workload. MAT incorporates tasks analogous to activities that aircraft crew members perform in flight, while providing a high degree of experiment control, performance data on each subtask, and freedom to use non-pilot test subjects. The MAT battery primary display is composed of four separate task windows: a monitoring task window which includes gauges and warning lights, a tracking task window for the demands of manual control, a communication task window to simulate air traffic control communications, and a resource management task window which permits maintaining target levels on a fuel management task. In addition, a scheduling task window gives the researcher information about future task demands. The battery also provides the option of manual or automated control of tasks. The task generates performance data for each subtask. The task battery may be paused and onscreen workload rating scales presented to the subject. The MAT battery was designed to use a serially linked second computer to generate the voice messages for the Communications task. The MATREMX program and support files, which are included in the MAT package, were designed to work with the Heath Voice Card (Model HV-2000, available through the Heath Company, Benton Harbor, Michigan 49022); however, the MATREMX program and support files may easily be modified to work with other voice synthesizer or digitizer cards. The MAT battery task computer may also be used independent of the voice computer. MAT, LAR-14904, is written in QuickBasic and assembly language for IBM PC series and compatible computers running MS-DOS. The code in MAT is written for Microsoft QuickBasic 4.5 and Microsoft Macro Assembler 5.1. This package requires a joystick and EGA or VGA color graphics. An 80286, 386, or 486 processor machine is highly recommended. The standard distribution medium for MAT is a 5.25 inch 360K MS-DOS format diskette. The files are compressed using the PKZIP file compression utility. PKUNZIP is included on the distribution diskette. Program $200; documentation $16. NUCLEAR ROCKETS One of the most important factors in the development of nuclear rocket engine designs is to be able to accurately predict temperatures and pressures throughout a fission nuclear reactor core with axial hydrogen flow through circular coolant passages. CAC, from NASA Lewis Research Center, is an analytical prediction program to study the heat transfer and fluid flow characteristics of a circular coolant passage. CAC predicts as a function of time axial and radial fluid conditions, passage wall temperatures, flow rates in each coolant passage, and approximate maximum material temperatures. Although CAC was originally developed in FORTRAN IV for use on an IBM 7094, this version is written in ANSI standard FORTRAN 77 and is designed to be machine independent. It has been successfully compiled on IBM PC series and compatible computers running MS-DOS with Lahey F77L, a Sun4 series computer running SunOS 4.1.1, and a VAX series computer running VMS 5.4-3. CAC requires 300K of RAM under MS-DOS, 422K of RAM under SunOS, and 220K of RAM under VMS. No sample executable is provided on the distribution medium. Sample input and output data are included. The standard distribution medium for this program is a 5.25 inch 360K MS-DOS format diskette. CAC, LEW-15400, was developed in 1966, and this machine independent version was released in 1992. Program $450; documentation $36. THERMAL ANALYSIS HEAT.PRO, from NASA's Jet Propulsion Laboratory, calculates the thermal imbalance force resulting from satellite surface heating. The heated body of a satellite re-radiates energy at a rate that is proportional to its temperature, losing the energy in the form of photons. By conservation of momentum, this momentum flux out of the body creates a reaction force against the radiation surface, and the net thermal force can be observed as a small perturbation that affects long term orbital behavior of the satellite. HEAT.PRO calculates this thermal imbalance force and then determines its effects on satellite orbits, especially where the Earth's shadowing of an orbiting satellite causes periodic changes in the spacecraft's thermal environment. HEAT.PRO implements a finite element method routine called PDE2D which incorporates material properties to determine the solar panel surface temperatures. HEAT.PRO, NPO-18665, was written in FORTRAN 77 for Cray series computers running UNICOS. The source code contains directives for and is used as input to the required partial differential equation solver, PDE2D. HEAT.PRO is available on a 9-track 1600 BPI magnetic tape in UNIX tar format (standard distribution medium) or a .25 inch streaming magnetic tape cartridge in UNIX tar format. NOTE: PDE2D is available from Granville Sewell, Mathematics Dept., University of Texas at El Paso, El Paso, Texas 79968. Program $500; documentation $12. IMAGE ANALYSIS RATIO_TOOL, from NASA's Jet Propulsion Laboratory, is an interactive program for viewing and analyzing large multispectral image data sets that have been created by an imaging spectrometer. While the standard approach to classification of multispectral data is to match the spectrum for each input pixel against a library of known mineral spectra, RATIO_TOOL uses ratios of spectral bands in order to spot significant areas of interest within a multispectral image. Each image band can be viewed iteratively, or a selected image band of the data set can be requested and displayed. When the image ratios are computed, the result is displayed as a gray scale image. At this point a histogram option helps in viewing the distribution of values. A thresholding option can then be used to segment the ratio image result into two to four classes. The segmented image is then color coded to indicate threshold classes and displayed alongside the gray scale image. RATIO_TOOL, NPO-18770, is written in C language for Sun series computers running SunOS 4.0 and later. It requires the XView toolkit and the OpenWindows window manager (version 2.0 or 3.0). The XView toolkit is distributed with Open Windows. A color monitor is also required. The standard distribution medium for RATIO_TOOL is a .25 inch streaming magnetic tape cartridge in UNIX tar format. An electronic copy of the documentation is included on the program media. RATIO_TOOL is a copyrighted work with all copyright vested in NASA. Program $900; documentation $20. AUTOMATIC DATA CLASSIFICATION The standard approach to classification in much of artificial intelligence and statistical pattern recognition research involves partitioning of the data into separate subsets, known as classes. AUTOCLASS III, from NASA Ames Research Center, uses the Bayesian approach in which classes are described by probability distributions over the attributes of the objects, specified by a model function and its parameters. The calculation of the probability of each object's membership in each class provides a more intuitive classification than absolute partitioning techniques. AUTOCLASS III is applicable to most data sets consisting of independent instances, each described by a fixed length vector of attribute values. An attribute value may be a number, one of a set of attribute specific symbols, or omitted. The user specifies a class probability distribution function by associating attribute sets with supplied likelihood function terms. AUTOCLASS then searches in the space of class numbers and parameters for the maximally probable combination. It returns the set of class probability function parameters, and the class membership probabilities for each data instance. AUTOCLASS III, ARC-13180, is written in Common Lisp, and is designed to be platform independent. This program has been successfully run on Symbolics and Explorer Lisp machines. It has been successfully used with the following implementations of Common LISP on the Sun: Franz Allegro CL, Lucid Common Lisp, and Austin Kyoto Common Lisp and similar UNIX platforms; under the Lucid Common Lisp implementations on VAX/VMS v5.4, VAX/Ultrix v4.1, and MIPS/Ultrix v4, rev. 179; and on the Macintosh personal computer. The minimum Macintosh required is the IIci. This program will not run under CMU Common Lisp or VAX/VMS DEC Common Lisp. A minimum of 8Mb of RAM is required for Macintosh platforms and 16Mb for workstations. The standard distribution medium for this program is a .25 inch streaming magnetic tape cartridge in UNIX tar format. It is also available on a 3.5 inch diskette in UNIX tar format and a 3.5 inch diskette in Macintosh format. An electronic copy of the documentation is included on the distribution medium. Program $900; documentation $21. HELICOPTER WAKES The prediction of inflow to a helicopter rotor and the wake velocities below and behind are vital to the calculation of airloads on the rotor blades of a helicopter. DOWN, from NASA Langley Research Center, is a computer program that assists designers with such predictions. DOWN was created to implement a flat wake theory, a simple analysis for the calculation of rotor inflow and wake velocities. The analysis essentially treats the rotor wake geometry as rigid without interaction between induced velocities and wake structure. The code will predict three orthogonal incremental components of flow velocity at any point in any plane parallel or perpendicular to the rotor disk. Input to the code is entered interactively through the computer keyboard. The coded version of flat wake theory as implemented in DOWN provides vertical inflow patterns similar to experimental patterns for helicopter flight speeds greater than 60 knots. DOWN, LAR-14841, is written in FORTRAN 77 for IBM PC series and compatible computers running MS-DOS. It requires 56K of RAM for execution. This package includes sample executables which were compiled under Microsoft FORTRAN. The standard distribution medium for this program is one 5.25 inch 360K MS-DOS format diskette. Program $200; documentation $13. IMAGE PROCESSING IMAGEP, from NASA Lewis Research Center, is a FORTRAN computer algorithm containing various image processing, analysis, and enhancement functions. It is a keyboard-driven program organized into nine subroutines. Within the subroutines are other routines, also, selected via keyboard. Some of the functions performed by IMAGEP include digitization, storage and retrieval of images; image enhancement by contrast expansion, addition and subtraction, magnification, inversion, and bit shifting; display and movement of cursor; display of grey level histogram of image; and display of the variation of grey level intensity as a function of image position. This algorithm has possible scientific, industrial, and biomedical applications in material flaw studies, steel and ore analysis, and pathology, respectively. IMAGEP, LEW-15370, is written in VAX FORTRAN for DEC VAX series computers running VMS. The program requires the use of a Grinnell 274 image processor which can be obtained from Mark McCloud Associates, Campbell, CA. An object library of the required GMR series software is included on the distribution media. IMAGEP requires 1Mb of RAM for execution. The standard distribution medium for this program is a 1600 BPI 9track magnetic tape in VAX FILES-11 format. It is also available on a TK50 tape cartridge in VAX FILES-11 format. Program $700; documentation $14. MAC NETS NETS, A Tool for the Development and Evaluation of Neural Networks from NASA Johnson Space Center, provides a simulation of Neural Network algorithms plus an environment for developing such algorithms. Problems which involve pattern matching readily fit the class of problems which NETS is designed to solve. The program allows the user to customize the patterns of connections between layers of a network. NETS also provides features for saving the weight values of a network during the learning process, which allows for more precise control over the learning process. NETS allows the user to generate C code to implement the network loaded into the system. This permits the placement of networks as components, or subroutines, in other systems. Once a network performs satisfactorily, the Generate C Code option provides the means for creating a program separate from NETS to run the network. Other features: files may be stored in binary or ASCII format; multiple input propagation is permitted; bias values may be included; capability to scale data without writing scaling code; quick interactive testing of network from the main menu; and several options that allow the user to manipulate learning efficiency. NETS is written in ANSI standard C language to be machine independent. The Macintosh version (MSC-22108) includes code for both a graphical user interface version and a command line interface version. The machine independent version (MSC-21588) only includes code for the command line interface version of NETS 3.0. This new Macintosh version requires a Macintosh II series computer and has been successfully implemented under System 7. Four executables are included on these diskettes, two for floating point operations and two for integer arithmetic. It requires Think C 5.0 to compile. A minimum of 1Mb of RAM is required for execution. Sample input files and executables for both the command line version and the Macintosh user interface version are provided on the distribution medium. The Macintosh version is available on a set of three 3.5 inch 800K Macintosh format diskettes. Program $150; documentation $20. RELIABILITY RISK D/C from NASA's Jet Propulsion Laboratory is a prototype program which attempts to do program risk modeling for the Space Exploration Initiative (SEI) architectures proposed in the Synthesis Group Report. Risk assessment is made with respect to risk events, their probabilities, and the severities of potential results. The program allows risk mitigation strategies to be proposed for an exploration program architecture and to be ranked with respect to their effectiveness. RISK D/C allows for the fact that risk assessment in early planning phases is subjective. Although specific to the SEI in its present form, RISK D/C can be used as a framework for developing a risk assessment program for other specific uses. RISK D/C, NPO-18740, was developed for Macintosh series computers. It requires HyperCard 2.0 or later, as well as 2Mb of RAM and System 6.0.8 or later. A Macintosh II series computer is recommended due to speed concerns. The standard distribution medium for this package is one 3.5 inch 800K Macintosh format diskette. RISK D/C Is a copyrighted work with all copyright vested in NASA. Program $150; documentation $14. PROJECT MANAGEMENT RSM, a Resupply Scheduling Modeler from NASA Lewis Research Center, is a fully menu-driven program that uses integer programming techniques to determine an optimum schedule for replacing components on or before the end of a fixed replacement period. Although written to analyze the electrical power system on the Space Station Freedom, RSM is quite general and can be used to model the resupply of almost any system subject to user- defined resource constraints. RSM is based on a specific form of the general linear programming problem in which all variables in the objective function and all variables in the constraints are integers. While more computationally intensive, integer programming was required for accuracy when modeling systems with small quantities of components. RSM, LEW-15309, is written in APL2 for IBM PC series computers and compatibles. A stand-alone executable version of RSM is provided; however, this is a "packed" version of RSM which can only utilize the memory within the 640K DOS limit. This executable requires at least 640K of memory and DOS 3.1 or higher. Source code for an APL2/PC workspace version is also provided. This version of RSM can make full use of any installed extended memory but must be run with the APL2 interpreter; and it requires an 80486 based microcomputer or an 80386 based microcomputer with an 80387 math coprocessor, at least 2Mb of extended memory, and DOS 3.3 or higher. The standard distribution medium for this package is one 5.25 inch 360K MS-DOS format diskette. Program $200; documentation $16.
