Software Design for CFD Rotary-Wing Aeromechanics Modeling

Helicopter flight involves many multidisciplinary physics problems that are difficult to predict with today’s engineering modeling and simulation tools. Rotor aerodynamic systems involve complex interactions among the rotor blades, rotor wakes, and fuselage, and they create challenges such as simultaneous modeling of rotating and nonrotating components; retreating-blade, low-speed dynamic stall; advancing-blade transonic flow; rotor “trim” requirements to balance aerodynamic and dynamic forces for particular control settings; and strong coupling between rotor-blade aerodynamics and rotor blade dynamics (both rigid and elastic blade motion).

Crumple Zone Software Absorbs Attack Effects Before System Failures

A higher level of structural and operational endurance and ruggedness can be achieved in software systems by strategically introducing crumple zones (CZs) in the system architecture. Analogous to the crumple zone in an automobile, a CZ stands before critical components and “absorbs” the effects of attacks by localizing or eliminating the damage they can cause and leaving the critical components intact and unaffected. The concept of software CZs is broadly applicable; this work focuses on CZs for SOA.

General Runtime/Architecture for Many-core Parallel Systems (GRAMPS)

The era of obtaining increased performance via faster single cores and optimized single-thread programs is over. Instead, a major factor in new processors’ performance comes from parallelism: increasing numbers of cores per processor and threads per core. In both research and industry, runtime systems, domain-specific languages, and more generally, parallel programming models, have become the tools to realize this performance and contain this complexity.

Weapon Center of Mass Calculator

The Weapon Center of Mass (COM) software allows researchers to easily determine mass properties of a weapon system. The tool presents a photograph of the weapon and allows the user to place weight anywhere on the weapon by clicking on the screen. After the weight is placed, the software returns the mass properties of the weapon, including the effects of the added weight. It is based on fundamental equations found in physics and biomechanics, and can determine the effects of as many as four added weights. The added weight can be accoutrements (such as new sights), additional weapons (such as a grenade launcher), or any other object that is mounted to the weapon.

Software System for Microbial Genome Sequence Annotation

The annotation of genomes from next-generation sequencing platforms needs to be rapid, high-throughput, and fully integrated and automated. Although a few Web-based annotation services have recently become available, they may not be the best solution for researchers that need to annotate a large number of genomes, possibly including proprietary data, and store them locally for further analysis.

Environmental Awareness of Sensor and Emitter Employment

Many Army missions rely on effective sensing capabilities that provide intelligence on the adversary, and protect friendly forces from enemy detection. Sensors that are stationary (microphones, geophones, and ground-based radars) and moving (cameras on unattended aerial vehicles and ground vehicles) assist operations such as persistent surveillance of small, forward-operating bases, and rapid covert troop maneuvers in the air and on the ground. When advantageous, sensing is often performed in multiple signal modalities including visible, infrared, acoustic, seismic, radiofrequency, chemical, and biological.

Medical Information Network Decision Support System

In order to facilitate a more rapid and systematic transfer of new medical knowledge and capabilities into mainstream clinical practice, a new Medical Information Network Decision Support (MINDS) system has been proposed. This system is intended to be a platform for storing and fusing medical data across all levels (e.g. from low-level genomic and proteomic data to higher level clinical data) in a standardized way.

Virtual Network Computing Software for DataWall Remote Display

VNC (Virtual Network Computing) is open-source software that allows a user to view and interact with a remote computer (known as the VNC server) from a local computer (known as the VNC viewer/client). VNC is used to display multiple remote desktops on the DataWall. The original VNC software can only project the whole desktop from a server to the DataWall. The VNC server and viewer were modified to project the whole desktop or an application of interest from a server to the DataWall.

Software Suite for a Large Defense System

A suite of software tools was developed to enable networks composed of many hundreds, thousands, or even millions of commodity computers to protect themselves against a variety of security threats. These tools include Anagram, a content-based anomaly detection (AD) tool; ASSURE, which provides automatic software self-healing; and Aeolos, a distributed intrusion detection and event correlation infrastructure.
