As one of a series of studies being conducted to develop a useful (predictive) model of the instructional design process that is appropriate to military technical training settings, this study performed initial evaluations on two pieces of instructional design software developed by M. David Merrill and colleagues at Utah State University i.e., Merrill's Naming Transaction Shell and Merrill's Checklist Procedures Transaction Shell. The software provided the capability to design, develop, and deliver computer-based instruction for teaching both the parts of a device and simple checklist procedures pertaining to the device. The primary objective of the study was to identify the relevant variables to be used in determining the acceptability, the generalizability, and the effectiveness of the instructional design software. In an initial study, the Naming Transaction Shell was evaluated by a subject matter expert with no previous computer experience who was an instructor at the U.S. Air Force Academy. A second study conducted with six subject matter experts and the same instructor used two transaction shells--naming the parts and checklist procedures. In each study, subjects had about 30 hours to design and develop a lesson module for one hour of student instruction. In the second study, a simple drawing program was used to create graphics. Both studies indicate that the transaction shells provided a highly cost-effective authoring environment and that this approach has good potential for courseware authoring. (SLD)

The Autonomous Multi-Agent Physically Interacting Spacecraft (AMPHIS) test bed examines the problem of multiple spacecraft interacting at close proximity. This thesis contributes to this on-going research by addressing the development of the software architecture for the AMPHIS spacecraft simulator robots and the implementation of a Light Detection and Ranging (LIDAR) unit to be used for state estimation and navigation of the prototype robot. The software modules developed include: user input for simple user tasking; user output for data analysis and animation; external data links for sensors and actuators; and guidance, navigation and control (GNC). The software was developed in the SIMULINK/MATLAB environment as a consistent library to serve as stand alone simulator, actual hardware control on the robot prototype, and any combination of the two. In particular, the software enables hardware-in-the-loop testing to be conducted for any portion of the system with reliable simulation of all other portions of the system. The modularity of this solution facilitates fast proof-of-concept validation for the GNC algorithms. Two sample guidance and control algorithms were developed and are demonstrated here: a Direct Calculus of Variation method, and an artificial potential function guidance method. State estimation methods are discussed, including state estimation from hardware sensors, pose estimation strategies from various vision sensors, and the implementation of a LIDAR unit for state estimation. Finally, the relative motion of the AMPHIS test bed is compared to the relative motion on orbit, including how to simulate the on-orbit behavior using Hill's equations.

Different Department of Defense communities prepare models for architecture compliance (e.g., to maintain JCIDS requirements), for simulation purposes (e.g. for performance estimates) and software engineering (e.g, for model-based code generation). Little, if any, information transfer and model reuse takes place across these communities of interest, which leads to redundant efforts, models that are out of sync, and lost domain knowledge. Differences in methods, tools and data formats are a major reason for this disconnect. The charter of RT 24 was to investigate mechanisms that could help bridge the divide between the modeling & simulation, software engineering, and enterprise architecture modeling communities.

Simulation models typically possess primitive user interfaces. Users must spend substantial amounts of time learning the model before they gain proficiency in using the model. A versatile, user-friendly interface reduces the time and frustration involved in learning a new system. This research effort designs a user-friendly interface for the System Dynamics Model of Software Management. The interface is written in a batch programming language, compatible with the IBM personal micro-computer. The interface is a product of the prototype design approach. A sophisticated batch language provides the self- generating menu structures, advanced string handling capabilities, and color enhancements.

The project involved the design and implementation of a data dictionary system in a distributed development enviornment. The distributed environment consists of a central computer that hosts a database management system, a conglomerate of workstations, and the communications links between the workstations and central computer. The emphasis of the research was placed on the design of a user-friendly data dictionary editor that was implemented on a prototype workstation. Data dictionary definitions are created and updated at the workstation and transfered between the workstation and central computer database. Background information is provided on data dictionary systems, aspects of human-computer interfaces, and distributed environment interface issues. The design and development of the special editor and the database interface software are described in detail in this thesis.

An analysis and an interactive computer program are described through which minimum weight designs of composite, stiffened, cylindrical panels can be obtained subject to general and local buckling constraints and stress and strain constraints. The panels are subjected to arbitrary combinations of in-plane axial, circumferential, and shear resultants. Nonlinear material effects are included if the material is isotropic or has stiffness in only one direction (as does a discrete or a smeared stiffener). Several types of general and local buckling modes are included as constraints in the optimization process, including general instability, panel instability with either stringers or rings smeared out, local skin buckling, local crippling of stiffener segments, and general, panel, and local skin buckling including the effects of stiffener rolling. Certain stiffener rolling modes in which the panel skin does not deform but the cross section of the stiffener does deform are also accounted for. The interactive PANDA system consists of three independently executed modules that share the same data base. In the first module an initial design concept with rough (not necessarily feasible or accurate) dimensions are provided by the user in a conversational mode. In the second module the user decides which of the design parameters of the concept are to be treated by PANDA as decision variables in the optimization phase. In the third module the optimization calculations are carried out. Many examples are provided in which optimum designs obtained by PANDA are compared to those in the literature. (Author)

The Vehicle Integrated Defense System (VIDS) incorporates several packages of application software written in Ada. This report describes the preliminary design and code generation of one of the critical packages, the Threat Resolution Module (TRM). The necessary logic design, table, and file creation and other tasks to implement a preliminary TRM was accomplished. All programming was written in the DOD standard Higher Order Language of Ada. Work was done on the UNISTAR 200 workstation hosting an Ada Compiler developed by TeleSoft Corporation and targeting the MC68000 microcomputer. The operating system for the software development was UNIX. This report describes the feasibility of the VIDS-DMS software design approach by discussing the three principal topics of: 1. Software algorithm design technology; 2. Code generation, edit, and debug using Ada as the PDL; and 3. Test of the preliminary TRM on a skeleton operating system (testbed). The annotated source code of the software as well as the object code for the TRM is delivered under separate cover with this report to TACOM. This data, in conjunction with the 'lessons learned' during the experimental development project form the baseline for continued development of the VIDS-DMS Feasibility Demonstration Model software.

The Rome Air Development Center has developed the Software Quality Framework as a means to specify software quality goals and measure software quality. Much of the work to date has focused on metrics applicable to software code. This report describes an effort undertaken to measure the quality of software products earlier in the software development life cycle, during the design phase, and to automate the capture of metric data from design media. Metrics of software quality, primarily those related to the criterion simplicity (or conversely, complexity), were reviewed. This review includes those metrics previously developed in the Software Quality Framework. Two metrics, Halstead's Software Science and McCabe's Cyclomatic Complexity were chosen for their amenability to measurement during design and their potential for automation. Two design media were used: Design Aids for Real-Time Systems, an experimental automated design tool developed at the Charles Stark Draper Laboratory; and Ada as a program design language.

Human limb segment angle tracking requires a system which can track through all orientations. The major problem addressed by this research was to develop a real time inertial motion tracking system based on quaternions to overcome the singularities of Euler angle filters. This work involves clarification of the theory behind quaternion attitude estimation and development of a system capable of determining the orientation of an object in world coordinates. System sensors were built using miniature accelerometers, rate sensors, and magnetometers. The software system was designed by using Unified Modeling Language (UML) with object oriented design techniques. The actual implementation created a real time orientation tracking system. The system was tested with dynamic tilt table experiments. Test results showed that the quaternion attitude estimation filter system can track human limb segments in real time within 1 degree of accuracy in an orientation and with a 55 Hz update rate.

The Joint Army/Navy Rotorcraft Analysis and Design (JANRAD) computer program has been developed at the Naval Postgraduate School to aid in the preliminary design of rotorcraft and has been updated to include a Graphical User Interface (Gul). This thesis is a continuation of the program focusing on stability and control analysis. The trim solution for a specified flight condition is computed from the Performance module of the program. This trim solution is then used to compute stability derivatives for the specified flight condition and a linear state space model is created. This solution can then be used to perform various time and frequency domain analyses or can be saved to a file for future use.

The current development of applications for sensor-based robotic and automation (R&A) systems is typically a 'one-of-a-kind' process, where most software is developed from scratch, even though much of the code is similar to code written for other applications. The cost of these systems can be drastically reduced and the capability of these systems improved by providing a suitable software framework for all R&A systems. We describe a novel software framework, based on the notion of dynamically reconfigurable software for sensor-based control systems. Tools to support the implementation of this framework have been built into the Chimera 3.0 Real-Time Operating System. The framework provides for the systematic development and predictable execution of flexible R&A applications while maintaining the ability to reuse code from previous applications. It combines object-oriented design of software with port- automaton design of digital control systems. A control module is an instance of a class of port-based objects.

The Framework Programmable Software Development Platform (FPP) is a project aimed at combining effective tool and data integration mechanisms with a model of the software development process in an intelligent integrated software environment. Guided by the model, this system development framework will take advantage of an integrated operating environment to automate effectively the management of the software development process so that costly mistakes during the development phase can be eliminated. The focus here is on the design of components that make up the FPP. These components serve as supporting systems for the Integration Mechanism and the Framework Processor and provide the 'glue' that ties the FPP together. Also discussed are the components that allow the platform to operate in a distributed, heterogeneous environment and to manage the development and evolution of software system artifacts.

A collaborative approach to software development is described. The approach employs the agile development techniques: project retrospectives, Scrum status meetings, and elements of Extreme Programming to efficiently develop a cohesive and extensible software suite. The software product under development is a fluid dynamics simulator for performing aerodynamic and aerothermodynamic analysis and design. The functionality of the software product is achieved both through the merging, with substantial rewrite, of separate legacy codes and the authorship of new routines. Examples of rapid implementation of new functionality demonstrate the benefits obtained with this agile software development process. The appendix contains a discussion of coding issues encountered while porting legacy Fortran 77 code to Fortran 95, software design principles, and a Fortran 95 coding standard.

Advances in mirror fabrication is making very large space based telescopes possible. In the many applications, only monolithic mirrors meet the performance requirements. The existing and near-term planned heavy launch vehicles place a premium on lowest possible mass. Again, available and planned payload shroud size limits near term designs to 4 meter class mirror. Practical 8 meter and beyond designs could encourage planners to include larger shrouds if it can be proven that such mirrors can be manufactured. These two factors lower mass and larger mirrors, presents the classic optimization problem. There is a practical upper limit to how large a mirror can be supported by a purely kinematic mount system and be launched. This paper shows how the design of the suspension system and mirror blank needs to be designed simultaneously. We will also explore the concepts of auxiliary support systems, which act only during launch and disengage on orbit. We will define required characteristics of these systems and show how they can substantially reduce the mirror mass. The AMTD project is developing and maturing the processes for future replacements for HUBBLE, creating the design tools, validating the methods and techniques necessary to manufacture, test and launch extremely large optical missions. This paper will use the AMTD 4 meter "design point" as an illustration of the typical use of the modeler in generating the multiple models of mirror and suspension systems used during the conceptual design phase of most projects. The influence of Hexapod geometry, mirror depth, cell size and construction techniques (Exelsis Deep Core Low Temperature Fusion (c) versus Corning Frit Bonded (c) versus Schott Pocket Milled Zerodur (c) in this particular study) are being evaluated. Due to space and time consideration we will only be able to present snippets of the study in this paper. The advances in manufacturing techniques for lightweight mirrors, such as EXELSIS deep core low temperature fusion, Corning's continued improvements in the Frit bonding process and the ability to cast large complex designs, combined with water-jet and conventional diamond.

In this report, I will discuss the tasks and projects I have completed while working as an electrical engineering intern during the spring semester of 2016 at NASA Kennedy Space Center. In the field of software development, I completed tasks for the G-O Caching Mobile App and the Asbestos Management Information System (AMIS) Web App. The G-O Caching Mobile App was written in HTML, CSS, and JavaScript on the Cordova framework, while the AMIS Web App is written in HTML, CSS, JavaScript, and C# on the AngularJS framework. My goals and objectives on these two projects were to produce an app with an eye-catching and intuitive User Interface (UI), which will attract more employees to participate; to produce a fully-tested, fully functional app which supports workforce engagement and exploration; to produce a fully-tested, fully functional web app that assists technicians working in asbestos management. I also worked in hardware development on the Integrated Display and Environmental Awareness System (IDEAS) wearable technology project. My tasks on this project were focused in PCB design and camera integration. My goals and objectives for this project were to successfully integrate fully functioning custom hardware extenders on the wearable technology headset to minimize the size of hardware on the smart glasses headset for maximum user comfort; to successfully integrate fully functioning camera onto the headset. By the end of this semester, I was able to successfully develop four extender boards to minimize hardware on the headset, and assisted in integrating a fully-functioning camera into the system.

A NASA contractor and Small Business Innovation Research (SBIR) participant has converted its research into commercial software products for auto design, structural analysis and other applications. ViGYAN, Inc., utilizing the aeronautical research principle of computational fluid dynamics, has created - with VGRID3D and VPLOT3D - an easier alternative to conventional structured grids for fluid dynamic calculations.

This practicum was designed to increase the skills of 13 middle school students with learning and behavioral disabilities in the use of personal productivity software. In addition, teacher training and motivational activities were included. Consultation with the school technology instructor and creative scheduling provided the students with hours of training in the technology lab. Celebrations were held regularly and included presentation of awards and guest speakers. Lesson plans were developed that were designed to teach the students the basic functions of the word processing, multimedia, spreadsheet, and Internet functions of the software available on the computers in the school setting. Training was provided to the teacher to effectively plan for and supervise the students throughout the implementation period. Surveys as well as pretest and posttest data showed that the majority of students increased their knowledge of the available technology. The students were able to produce documents, spreadsheets, and multimedia presentations. The data showed that the students felt more competent to complete academic tasks after the training. The teacher also became more confident with integrating technology into the students' individualized education programs. Appendices include the lesson plans and evaluation results.

This study explored the collaborative production of mathematical knowledge during computer-mediated learning activities. In particular, it focused on opportunities for undergraduate students from a local university to collaborate with elementary-aged at-risk children on commercially available computer games in an urban after-school club. Two types of qualitative data collection techniques were employed: participant observation notes and videotapes of participants interacting at computers. The study focuses on two participants, a fourth grader and a third-year undergraduate student. Undergraduate participation in the after-school club was found to play a significant role in organizing collaborative activities for children. While many of the strategies for collaboration used by the undergraduates did not necessarily lead to the co-production of mathematical talk or reasoning, that was not the case for explicit requests for explanations. When children had solved a problem, it was common for undergraduates to ask them what they did to accomplish the task; this resulted in the children giving explanations, although they tended to be brief and provide no evidence of deep understanding of mathematics. Results indicate that it is crucial for differences in problems to be systematically explored given that exploration of the mathematical patterns found in solution strategies provides children with opportunities to construct a deep understanding of principles underlying mathematics.

The shift toward multi-core processors is the most obvious implication of a greater trend toward efficient computing. In the past, hardware designers were willing to spend superlinear area and power for incremental performance improvements, but that era has come to an end.With the low-hanging fruit of processor microarchitecture having largely been picked, it is my belief that we will increasingly see a trend toward co-designing hardware with the software that runs on it.Processor designers will ask 'what minimal features and interfaces must be place in hardware to achieve our performance goals?' In this talk, I will discuss our recent work exploring a collection of hardware primitives for: 1) making trivial the implementation of speculative compiler optimizations (which both increase performance and reduce power consumption), 2) implementing a strongly-atomic Transactional Memory where common-case transactions execute in hardware with no overhead, but the semantics are defined by software, and 3) instrumenting code to collect profile information with negligible overhead. ©2008 Microsoft Corporation.

Line plotting is the one of the basic operations in the scan conversion. Bresenham’s line drawing algorithm is an efficient and high popular algorithm utilized for this purpose. This algorithm starts from one end-point of the line to the other end-point by calculating one point at each step. As a result, the calculation time for all the points depends on the length of the line thereby the number of the total points presented. In this paper, we developed an approach to speed up the Bresenham algorithm by partitioning each line into number of segments, find the points belong to those segments and drawing them simultaneously to formulate the main line. As a result, the higher number of segments generated, the faster the points are calculated. By employing 32 cores in the Field Programmable Gate Array, a line of length 992 points is formulated in 0.31μs only. The complete system is implemented using Zybo board that contains the Xilinx Zynq-7000 chip (Z-7010).

To cope with the soft errors and make full use of the multi-core system, this paper gives an efficient fault-tolerant hardware and software co-designed architecture for multi-core systems. And with a not large number of test patterns, it will use less than 33% hardware resources compared with the traditional hardware redundancy (TMR) and it will take less than 50% time compared with the traditional software redundancy (time redundant).Therefore, it will be a good choice for the fault-tolerant architecture for the future high-reliable multi-core systems.
