Model-based GN&C simulation and flight software development for Orion missions beyond LEO
2014 Edition, March 1, 2014 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

For Orion missions beyond low Earth orbit (LEO), the Guidance, Navigation, and Control (GN&C) system is being developed using a model-based approach for simulation and flight software. Lessons...

A model-based design and testing approach for Orion GN&C flight software development
2010 Edition, March 1, 2010 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The Orion Crew Exploration Vehicle (CEV) Guidance, Navigation, and Control (GN&C) design and analysis team are developing the onboard GN&C flight software (FSW) algorithms using the Matlab/Simulink tool suite to embrace a...

Accurate Non-Linearity Fully-Closed-Form Formula based on the GN/EGN Model and Large-Data-Set Fitting
2019 Edition, March 1, 2019 - Optical Society (The) (OSA)

We tested the accuracy of a fully-closed-form GN/EGN formula over 1,700 different fully-loaded systems. We improved it greatly through a correction that leverages the large data-set, providing an effective tool for real-time physical-layer-aware network management.

Offline Lightpath Allocation in All-Optical Networks with Impairment Aware RWA Based on the GN Model
2015 Edition, October 1, 2015 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This paper deals with the offline allocation of lightpaths in all-optical networks taking into consideration not only the wavelength continuity and non-overlapping constraints of the classic routing and wavelength assignment (RWA) problem but also the optical nonlinear impairments...

Towards a Route Planning Tool for Open Optical Networks in the Telecom Infrastructure Project
2018 Edition, March 1, 2018 - Optical Society (The) (OSA)

We explore the validity of the Gaussian-noise (GN) model as the basis for an open-source optical network planning tool. Experimental results and GN-model based predictions suggest the GN model a feasible choice for penalty...

Significant Anatomy Detection through Sparse Classification: A Comparative Study
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We present a comparative study for discriminative anatomy detection in high dimensional neuroimaging data. While most studies solve this problem using mass univariate approaches, recent works show better accuracy and variable selection using a sparse classification model. Two...

Q-availability based Virtual Optical Network Provisioning
2018 Edition, March 1, 2018 - Optical Society (The) (OSA)

We show significant gain in Virtual Optical Network (VON) capacity by provisioning based on Q-availabilities of optical channels instead of fixed Q-margin. The Q-availability is calculated using stochastic simulations based on GN model.

Open Optical Network Planning Demonstration
2019 Edition, March 1, 2019 - Optical Society (The) (OSA)

Planning optical networks in a multi-vendor environment calls for open and vendor agnostic simulation tools to compare different scenarios in "what-if?" analysis and determine the best performing solution. The PSE-Group in the Telecom Infra Project aims to facilitate...

CubeSat flight system development for enabling deep space science
2017 Edition, March 1, 2017 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The Jet Propulsion Laboratory is investing in a suite of core flight system technologies to enable CubeSats to conduct missions in deep space. These will be demonstrated on currently funded missions, such as INSPIRE, MarCO, and Lunar Flashlight, which will be among the...

Surface-Potential-Based Silicon Carbide Power MOSFET Model for Circuit Simulation
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Transistor models have been playing a key role in designing efficient power converters. As the operating frequency of the converters becomes higher, transistor models need to represent physical device behavior accurately. This paper proposes a comprehensive...
