There exist many datasets that can be viewed as multivariate time series, such as the daily high temperature at a locality, sensor recordings in diagnostic systems and scientific data, and music and video recordings. These time series reside in large...

A simple method of controlling recording and display of imaging spectrometer data in (airborne) flight was needed. Existing commercial packages were overly complicated, and sometimes difficult to operate in a bouncing plane. The software also was required to keep up with...

A series of scripts stitch together existing open-source Python modules for the purpose of displaying, cleaning, and measuring photometric properties within public Kepler data. The intent of these tools is to provide convenience to the Kepler science community, and to increase cost efficiency for the project....

This software provides the processing for a non-contact system that remotely estimates the heart rate and respiration rate of individuals as they carry on daily activities, and also enables detection of heart and respiration rate through walls.

Functional connections within the brain can be revealed through functional magnetic resonance imaging (fMRI), which shows simultaneous activations of blood flow in the brain during response tests. However, fMRI specialists currently do not have a tool for visualizing the complex data that comes from fMRI scans....

Viewpoints software allows interactive visualization of multi-variate data using a variety of standard techniques. The software is built exclusively from high-performance, cross-platform, open-source, standards-compliant languages, libraries, and components. The techniques included are:

When adapting GPS sensor technology from an aviation environment to a space environment, the search window for a satellite’s frequency and code phase is greatly increased. This problem is also magnified when multiple antennas are used. A new algorithm...

The development of the self-diagnostic accelerometer (SDA) is important to both reducing the in-flight shutdowns (IFSD) rate — and hence reducing the rate at which this component failure type can put an aircraft in jeopardy — and also as a critical enabling technology for future...

Wide-temperature and extreme-environment electronics are crucial to future missions. These missions will not have the weight and power budget for heavy harnesses and large, inefficient warm boxes. In addition, extreme-environment electronics, by their inherent nature, allow...

Polymeric and inorganic semiconductors offer relatively high quantum efficiencies, and are much less expensive and versatile to fabricate than non-amorphous silicon wafers. An optical fiber and cladding can be designed and fabricated to confine light for transport within ultraviolet and near-infrared media, using...

A new technology to create electrochemical double-layer supercapacitors is provided using carbon nanotubes as electrodes of the storage medium. This invention allows efficient transport between the capacitor electrodes through the porous nature of the nanotubes, and has a low interface resistance between...

A high level of autonomy is desired for future unmanned combat systems because lethality and survivability can be improved with much less communication bandwidth than would be necessary for preprogrammed or remotely operated systems. However, there are a number of technical...

Human space systems, such as the International Space Station (ISS) and future planned missions to the lunar surface and beyond, require the crew’s ability to locate and manage the physical resources that are required for use to achieve mission objectives. However, the...

This innovation is a tungsten-rhenium gauge that can be placed into an aft exit cone of a rocket motor. It will measure heat flux with time for the full duration of the RSRM (reusable solid rocket motor) nozzle environment with equal response time.

This software tool automates the statistical analysis of heating indicators for a family of trajectories. It allows for quick and clear relative comparison of the trajectories by concisely and meaningfully reducing an arbitrarily large set of body point heating into single values that are used to...

The magnetic sensitivity of a Ka-band isolator’s output phase is measured at 7 × 10–4 deg/G level. This high degree of precision is enabled by the sensitive phase measuring capabilities of a testbed built to mimic NASA’s Gravity Recovery and Interior Laboratory...

New hybrid computing systems consist of a multicore CPU (central processing unit) and one or more massively parallel accelerator devices, such as GPUs (graphics processing units). Effectively utilizing these systems involves using all of the available computational resources, which may be difficult to...

JPL Unified Methodology Process (JUMP) is an effort to establish a common frame of reference across OCIO (Office of Chief Information Officer) and EBIS (Enterprise Business Information Services Division). The iterative approach to project management is more powerful and efficient, enables better reviews, and...

The Automated Evaluation Software Web application was created using Java Enterprise technologies, which provided capabilities for dynamic report generation and Microsoft output. The Tomcat Application server makes the application robust, fast, and reliable. HTML 4.0 was used to create the user...

Engineering design models are normally developed using specific modeling tools such as Excel, Matlab, Maple, and Mathematica. It is difficult to connect various models written in different modeling environments and produce results without extensive effort. Phoenix ModelCenter is a...

Jim Odom served as project manager on the Hubble Space Telescope from 1983 to 1986. As the world celebrates Hubble’s 25th anniversary, Mr. Odom shared some of his experiences on the project.

This week's Question: This month, the Federal Aviation Administration proposed long-awaited rules on the commercial use of small drones, requiring operators to be certified, fly only during daylight, and keep their aircraft in sight. The ruling, for now, prevents drones from being used for a range of possible...

Harvard School of Engineering and Applied Sciences researchers developed an ultra-thin, completely flat lens made of a glass substrate and tiny, light-concentrating silicon antennas. Color correction is achieved in the single, miniaturized device.

This week's Question: Zero2infinity, a Spanish company, plans to launch passengers to near space using technologies called "Bloons." A maximum of four passengers will join two pilots in the Bloon cabin, which will be chained to a balloon filled with inert helium. Once fully inflated, the balloon will pull the cabin to...

Northumbria and Edinburgh Universities researchers have developed an innovative, new technique to harvest energy from carbon dioxide. The method may enable the creation of future power stations on the surface of Mars.The research proposes a new kind of engine for producing energy based...

Biorobotics researchers at the Institut des Sciences du Mouvement (Aix Marseille University) have developed the BeeRotor, a tethered flying robot. The robot adjusts its speed and follows terrain without an accelerometer or the measurement of altitude.
