Long And Short-Range Air Navigation On Spherical Earth, 2017 AAR Aerospace Consulting, LLC
Long And Short-Range Air Navigation On Spherical Earth, Nihad E. Daidzic
International Journal of Aviation, Aeronautics, and Aerospace
Global range air navigation implies non-stop flight between any two airports on Earth. Such effort would require airplanes with the operational air range of at least 12,500 NM which is about 40-60% longer than anything existing in commercial air transport today. Air transportation economy requires flying shortest distance, which in the case of spherical Earth are Orthodrome arcs. Rhumb-line navigation has little practical use in long-range flights, but has been presented for historical reasons and for comparison. Database of about 50 major international airports from every corner of the world has been designed and used in testing and route ...
A Physics-Based Approach To Modeling Wildland Fire Spread Through Porous Fuel Beds, 2017 University of Kentucky
A Physics-Based Approach To Modeling Wildland Fire Spread Through Porous Fuel Beds, Tingting Tang
Theses and Dissertations--Mechanical Engineering
Wildfires are becoming increasingly erratic nowadays at least in part because of climate change. CFD (computational fluid dynamics)-based models with the potential of simulating extreme behaviors are gaining increasing attention as a means to predict such behavior in order to aid firefighting efforts. This dissertation describes a wildfire model based on the current understanding of wildfire physics. The model includes physics of turbulence, inhomogeneous porous fuel beds, heat release, ignition, and firebrands. A discrete dynamical system for flow in porous media is derived and incorporated into the subgrid-scale model for synthetic-velocity large-eddy simulation (LES), and a general porosity-permeability model ...
A Software Architecture For Reconstructability Analysis, 2016 Portland State University
A Software Architecture For Reconstructability Analysis, Kenneth Willett, Martin Zwick
Software packages for reconstructability analysis (RA), as well as for related log linear modeling, generally provide a fixed set of functions. Such packages are suitable for end‐users applying RA in various domains, but do not provide a platform for research into the RA methods themselves. A new software system, Occam3, is being developed which is intended to address three goals which often conflict with one another to provide: a general and flexible infrastructure for experimentation with RA methods and algorithms; an easily‐configured system allowing methods to be combined in novel ways, without requiring deep software expertise; and a ...
Three Body Interactions Of Rare Gas Solids Calculated Within The Einstein Model, 2016 University of Tennessee, Knoxville
Three Body Interactions Of Rare Gas Solids Calculated Within The Einstein Model, Dan D'Andrea
Three body interactions can become important in solids at higher pressures and densities as the molecules can come into close contact. At low temperatures, accurate studies of three body interactions in solids require averaging the three-body terms over the molecules' zero point motions. An efficient, but approximate, averaging approach is based on a polynomial approximation of the three-body term. The polynomial approximation can be developed as a function of the symmetry coordinates of a triangle displaced from its average geometry and also as a function of the Cartesian zero point displacements from each atom’s average position. The polynomial approximation ...
Teaching Complex Theoretical Multi-Step Problems In Ict Networking Through 3d Printing And Augmented Reality, 2016 Central Queensland University
Teaching Complex Theoretical Multi-Step Problems In Ict Networking Through 3d Printing And Augmented Reality, Michael Cowling, James Birt
This paper presents a pilot study rationale and research methodology using a mixed media visualisation (3D printing and Augmented Reality simulation) learning intervention to help students in an ICT degree represent theoretical complex multi-step problems without a corresponding real world physical analog model. This is important because these concepts are difficult to visualise without a corresponding mental model. The proposed intervention uses an augmented reality application programmed with free commercially available tools, tested through an action research methodology, to evaluate the effectiveness of the mixed media visualisation techniques to teach ICT students networking. Specifically, 3D models of network equipment will ...
Towards A Pedagogy Of Comparative Visualization In 3d Design Disciplines, 2016 Bond University
Towards A Pedagogy Of Comparative Visualization In 3d Design Disciplines, James Birt, Jonathan Nelson, Dirk Hovorka
Spatial visualization and interpretation are important skills for designers. However, these skills generally require significant experiential development over the course of years. Visualizations allow the human brain to convey complex spatial concepts in intuitive, navigable and manipulable forms improving learner outcomes and perceptions. But often these visualizations are studied as single modality solutions. Dual modality and multimedia presentation studies show positive improvements in learner outcomes but dual modality is often difficult to compare. This paper presents ongoing research in the use of comparative multimodal visualizations produced with emerging technology solutions in 3D Design classrooms. Presented are previous findings from multimedia ...
Towards Comprehensive Parametric Code Generation Targeting Graphics Processing Units In Support Of Scientific Computation, 2016 The University of Western Ontario
Towards Comprehensive Parametric Code Generation Targeting Graphics Processing Units In Support Of Scientific Computation, Ning Xie
Electronic Thesis and Dissertation Repository
The most popular multithreaded languages based on the fork-join concurrency model (CIlkPlus, OpenMP) are currently being extended to support other forms of parallelism (vectorization, pipelining and single-instruction-multiple-data (SIMD)). In the SIMD case, the objective is to execute the corresponding code on a many-core device, like a GPGPU, for which the CUDA language is a natural choice. Since the programming concepts of CilkPlus and OpenMP are very different from those of CUDA, it is desirable to automatically generate optimized CUDA-like code from CilkPlus or OpenMP.
In this thesis, we propose an accelerator model for annotated C/C++ code together with an ...

Mining Revision Histories To Detect Cross-Language Clones Without Intermediates, 2016 Singapore Management University
Mining Revision Histories To Detect Cross-Language Clones Without Intermediates, Lingxiao Jiang, Zhiming Peng, Lingxiao Jiang, Hao Zhong, Haibo Yu, Jianjun Zhao
Research Collection School Of Information Systems
To attract more users on different platforms, many projects release their versions in multiple programming languages (e.g., Java and C#). They typically have many code snippets that implement similar functionalities, i.e., cross-language clones. Programmers often need to track and modify cross-language clones consistently to maintain similar functionalities across different language implementations. In literature, researchers have proposed approaches to detect cross-language clones, mostly for languages that share a common intermediate language (such as the .NET language family) so that techniques for detecting single-language clones can be applied. As a result, those approaches cannot detect cross-language clones for many projects ...
On The Feasibility Of Detecting Cross-Platform Code Clones Via Identifier Similarity, 2016 Singapore Management University
On The Feasibility Of Detecting Cross-Platform Code Clones Via Identifier Similarity, Lingxiao Jiang, Lingxiao Jiang, Hao Zhong, Haibo Yu, Jianjun Zhao
Research Collection School Of Information Systems
More and more mobile applications run on multiple mobile operating systems to attract more users of different platforms. Although versions on different platforms are implemented in different programming languages (e.g., Java and Objective-C), there must be many code snippets that implement the similar business logic on different platforms. Such code snippets are called cross-platform clones. It is challenging but essential to detect such clones for software maintenance. Due to the practice that developers usually use some common identifiers when implementing the same business logic on different platforms, in this paper, we investigate the identifier similarity of the same mobile ...
Examining Bridges Between Informal And Formal Learning Environments: A Sequential Mixed Method Design, 2016 University of Nebraska - Lincoln
Examining Bridges Between Informal And Formal Learning Environments: A Sequential Mixed Method Design, Dagen L. Valentine
Theses, Dissertations, & Student Scholarship: Agricultural Leadership, Education & Communication Department
The purpose of this sequential mixed method study was to identify schools implementing a technology-based engineering design intervention in a way that connects or bridges formal learning environments of the school-day to informal learning environments such as afterschool programs. Further, this study investigated educators’ decisions that enabled or facilitated bridging between formal and informal learning environments. This cooperation and/or linking between informal and formal learning time is bridging. Participants included public schools (n=16) in Eastern Nebraska that incorporated the Nebraska Wearables Technology (WearTec) program at their school, club or Out-of-School-Time program during the 2015-2016 school year. Three of ...

Information leaks currently represent a major security vulnerability. Malicious code, when injected into a trusted environment and executed in the context of the victim’s privileges, often results in the loss of sensitive information. To address this security issue, this paper focuses on the idea of information flow control using faceted execution . This mechanism allows the interpreter to efficiently keep track of variables across multiple security levels, achieving termination-insensitive non-interference (TINI). With TINI, a program can only leak one bit of data, caused by the termination of a program. One key benefit of having faceted execution is that flow ...

Modular Reasoning In The Presence Of Event Subtyping, 2016 Iowa State University
Modular Reasoning In The Presence Of Event Subtyping, Mehdi Bagherzadeh, Robert Dyer, Rex D. Fernando, Jose Sanchez, Hridesh Rajan
Computer Science Technical Reports
Separating crosscutting concerns while preserving modular reasoning is challenging. Type-based interfaces (event types) separate modularized crosscutting concerns (observers) and traditional object-oriented concerns (subjects). Event types paired with event specifications were shown to be effective in enabling modular reasoning about subjects and observers. Similar to class subtyping, organizing event types into subtyping hierarchies is beneficial. However, unrelated behaviors of observers and their arbitrary execution orders could cause unique, somewhat counterintuitive, reasoning challenges in the presence of event subtyping. These challenges threaten both tractability of reasoning and reuse of event types. This work makes three contributions. First, we pose and explain these ...
Software Improvements To Parint, A Parallel Integration Software Package, 2016 Western Michigan University
Software Improvements To Parint, A Parallel Integration Software Package, Lawrence Cuneaz
The best software is easy to configure and compile, is expandable and is well tested. Development of the ParInt software package for parallel integration stopped a number of years ago. When handed the software, parts of the package no longer configured or compiled consistently. Furthermore it relied on one random number generator and had no functional testing. The team tuned the auto configuration so that the program would configure and build on current systems, created expandable functionality to add new random number generators and created two functional test packs. Now ParInt can be developed with confidence knowing that it compiles ...
