Institutional Budgeting Tool (IBT)

The Jet Propulsion Laboratory's Institutional Budgeting Tool (IBT) was designed and developed to meet the needs of JPL's budget planners, numbering 1,600, who required a robust and state-of-the-art budgeting application. JPL's budgeting process had been constrained by legacy tools that presented usability and performance issues and lacked critical innovative budgeting features. IBT delivered superior user experience, system performance, and modern features necessary for essential laboratory budgeting.

Tubes Standards-Compliant C Header Library

Due to limitations imposed by transistor physics as device geometries continue to get finer and finer, the time when each new generation of processors was clocked faster than its predecessors is largely over. Nevertheless, as individual processor cores get smaller, chip manufacturers have turned instead to cramming a large number of cores onto a single die. Consequently, nearly all commercially available CPUs (central processing units), even those used in smartphones, already depend upon a multicore architecture. Unfortunately, the programming languages used for nearly all commercial software projects are really intended for generating code for a single CPU core. Though extensions exist that support multiple cores, it is something that is essentially tacked on, not part of the core language's constructs.

Techniques for Conducting Effective Concept Design and Design-to-Cost Trade Studies

Concept design plays a central role in project success for space missions, as the product of concept design effectively locks in the majority of system lifecycle cost. It involves a concurrent investigation of requirements and multiple mission characteristics such as flight dynamics, design, performance, concept of operations, technology, verification approach, launch and ground interfaces, cost, schedule, and risk.

HyDE Model-Based Diagnosis Engine for Stochastic Hybrid Systems

Model-based diagnosis deals with the problem of diagnosing faults in systems using a model of the system for guidance. This problem is complicated by the presence of hybrid dynamics in the system (continuous evolution of the system interspersed with discrete events like commands to change configuration), as well as uncertainties in the form of model approximations and sensor noise. Several model-based technologies have been developed and successfully demonstrated using discrete abstractions of the system as models. These techniques are severely restricted in model expressiveness due to the discrete nature of the models. Moreover, sophisticated model abstraction techniques, as well as algorithms to convert continuous data to discrete form, need to be developed for such an approach to work. Recently, there have been efforts to develop diagnostic engines for hybrid and stochastic systems. However, these techniques have either focused on parametric faults, or use a probabilistic approach to fault identification. Consistency-based approaches that have been successfully demonstrated using discrete models have not been extended to work with stochastic and hybrid models.

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.

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.
