Python Interface to Dual-Pol Radar Algorithms (DualPol)

This object-oriented Python module facilitates precipitation retrievals (e.g., hydrometeor type, precipitation rate, precipitation mass, particle size distribution) from polarimetric radar data. It leverages existing open-source radar software packages to perform all-in-one retrievals that are then easily visualized or saved using existing software.

Sound Lab (SLAB) Version 5

Interest in the simulation of acoustic environments has prompted a number of technology development efforts over the years for applications such as auralization of concert halls and listening rooms, spatial information displays in aviation, virtual reality, and better sound effects for video games. Each of these applications implies different task requirements that require different approaches in the development of rendering software and hardware.

CornerStone Knowledge Acquisition and Synthesis Framework

In general, and especially in the “big data” era, there is often a failure to collect sufficient data about the data (metadata). This lack of metadata drastically reduces the potential use of the data, and the attempt to rectify this situation after the fact is often difficult, if not impossible. The necessary metadata must first be located, and then organized and associated with the data. Often those who know about the metadata are no longer available. The proposed alternative is to prepare the data for long-term preservation based on currently accepted best-practices for long-term digital archives. This means that both the data and the metadata are simultaneously collected and prepared for the archive. This methodology provides the best chance that the necessary metadata will be available for future analysis, and ensures use of the data being collected and preserved.

Middle-Out Graph Analytics

This software visually lays out trends and patterns for ease of analysis, and can be used on desktop or handheld devices.

Graph analytics is a way of facilitating guided graph exploration through visual and interactive means. Unlike many graph visualization research efforts that focus predominantly on layout algorithms and rendering techniques, graph analytics research strives to provide an engaging interactive journey that bridges the gap from data to information to knowledge. Graph visualization still plays an important role in building this analytical journey, as do database querying, graph mining, interactive interrogation, human judgment, and senses.

NetEgg: Automated Code Generation for Software-Defined Networks

This software enables fast and easy network configuration.

Software-Defined Networking (SDN) usually requires network administrators to be skilled in programming languages such as C++, Python, or Ruby. Many IT operators tasked with installing routers or other network components may lack the skills to program SDN equipment. Due to a shortage of trained staff, implementing SDN across an entire enterprise can become very time-consuming and costly.

Robust Method for Data Protection and Change Detection

Methods exist for processing an original data sequence in order to generate information about the data for the purposes of integrity measurement, ownership demonstration, and authentication. The first category is digital watermarking, the second is data hashing, and the third is error detection coding. In the present context, watermarking is often used for ownership demonstration and authentication purposes; data hashing is often used for integrity measurement purposes; and as with data hashing, error detection coding is used to measure data integrity. However, the latter is normally done as part of data transmission protocol, and therefore addresses transmission errors rather than tampering.

Developing Safety-Critical System & Software Requirements

Requirements: The foundation of every safety-critical system. But as systems complexity expands and product development schedules compress, the foundation must support them. Guest presenter Vance Hilderman, CEO of safety-critical systems and software engineering consultancy AFuzion, explains how to build, maintain and reuse a rock-solid requirements foundation.

Uncertainty Quantification and Management in Digital Engineering

This Webinar illustrates applications of Uncertainty Quantification (UQ) techniques that will be necessary for full implementation of model-based digital engineering. The role of UQ techniques and software, such as SmartUQ, in end-to-end system models, reduced order modeling and probabilistic analysis, the creation of an authoritative digital surrogate “truth source”, and the creation of uncertainty budgets will be discussed.
