Searching, Exploring and Visualizing Data Using Maple

With the ever-expanding sea of available data and data repositories, navigating the vast quantities of information can be a difficult task. Maple, the advanced computing software from Maplesoft, is a powerful and interactive data visualization tool that can help users understand data characteristics through various techniques for visualization and analysis. Maple makes it easy to search, filter, explore and visualize varying types and quantities of data. This paper presents several examples of how Maple can be used to search and filter large data repositories, explore and visualize the data in innovative ways and use the data to predict future behavior.

Control Scheme Improves Motor Operation and Interaction

A team of researchers from the Polytechnic University of Bari, Italy, is working to improve how industrial electric drives operate. They propose a new control scheme that will not only improve motor operation, but also how the motor interacts with other systems.

Tool Helps Design Soft Robots That Can Bend and Twist

Designing a soft robot to move organically — to bend like a finger or twist like a wrist — has always been a process of trial and error. Now, researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences and the Wyss Institute for Biologically Inspired Engineering have developed a method to automatically design soft actuators based on the desired movement.

Scalable and Tileable Aggregate Low-Level Summary Display for Deep Space Network Link Control Tasks

This innovation features critical pieces of information in a single display.

The Deep Space Network (DSN) is a collection of three sites around the globe. The positioning of the sites, 120° longitude apart, allows at least one site to see every patch of sky at all times, thus facilitating continuous coverage for any deep space spacecraft that partners with the DSN.

Mission Service Architecture Framework (MSAF)

MSAF provides a common framework for designing a Mission Operations System (MOS) based on a control systems paradigm.

The representation of mission operations systems (MOS) has been unique to each mission, although there are many common concerns that need to be addressed. A consistent approach and language are needed for representing mission operations systems. The Mission Service Architecture Framework (MSAF) is a foundational extension of SysML and BPMN that provides stereotypes, relationships, and architectural system views that are used to describe mission operations systems.

Multi-Mission Operations System (MMOS)

MMOS provides a reference design for a Mission Operations System (MOS) and facilitates adaptation to meet mission-specific needs.

Each mission needs to develop a Mission Operations System (MOS). Without a standard design to use as a reference, system engineers typically look to a subset of previous missions and develop a system with a mix of heritage, new design, and in some cases, reinvention of existing capabilities. If a reference design were available, mission operations engineers would be able to begin with that reference and add or modify only those portions needed to fulfill a mission’s unique requirements.

Study of Formulating Conserved Scalar Equations for Turbulent Reactive Flows with General Species Mass- Diffusion Coefficients for Utilization in Flamelet Models

The modeling of turbulent reactive flows is a subject of contemporary research. Current turbulent-reaction models cannot account for realistic complexities such as distinct species mass-diffusion coefficients. Under the assumption of a single, constant, mass-diffusion coefficient, a conserved-scalar equation is typically derived in turbulent reactive flows by taking the difference between chemical-species conservation equations having opposite reaction rates (in the sense that the reactant has an opposite reaction rate to the product), thereby creating an equation devoid of reaction terms. Assuming the reaction regions are very thin and are merely contorted by turbulence, chemistry and turbulence can be decoupled, and the evolving statistics of the conserved scalar describe the reaction progression. No such equation has yet been derived for distinct mass-diffusion coefficient cases where the single coefficient is now replaced by a full matrix. Considering that mass diffusion is responsible for reactants approaching at the molecular level and for reaction initiation, this lack of mathematical framework is very disturbing.

HORIZON Framework for Distributed Data Management and Product Generation Workflow

The NASA Earth Observing System Data and Information System (EOSDIS) is a data-centric system designed for the processing and archiving from NASA’s Earth Observation missions and their distribution, as well as provision of specialized services to users. The major components of EOSDIS are 12 Distributed Active Archive Centers (DAACs), 14 Science Investigator-led Processing Systems (SIPSs), and the EOS Clearing House (ECHO). The DAACs play an import role within EOSDIS. They are divided by discipline with User Working Groups (UWGs) tailored to mission and objectives of the DAAC.

TIE: The Imagery Exchange for the NASA Global Imagery Browse Services (GIBS) Project

The NASA Earth Observing System Data and Information System (EOSDIS) is a data-centric system designed for processing and archiving from NASA’s Earth Observation missions and their distribution, as well as provision of specialized services to users. The major components of EOSDIS are 12 Distributed Active Archive Centers (DAACs), 14 Science Investigator-led Processing Systems (SIPSs), and the EOS Clearing House (ECHO). The Global Imagery Browse Services (GIBS) is the value-added image archive and access service for NASA Earth Science data products. It is the high-resolution global imagery solution for NASA. As the central imagery hub, GIBS is in need of an automated, scalable imagery capturing and generation solution.
