ASSIST (Adaptive Simple Sequencing Instruction Support Toolkit) is envisioned as a tool that will support instructional developers in creating adaptive and interactive SCORM conformant instruction. In Phase I, we developed an approach which focused on the concept of instructional activities: we began to develop an interface by which instructional developers could construct, revise, and reuse instr ...

Described is a highly compact two-phase microchannel condenser concept based on a two-phase loop evaporator design developed for cooling high performance servers in racks on Navy ships/submarines, a novel design that has demonstrated open-air evaporative heat transfer coefficients with water of 250,000 W/m2 K. The idea is to utilize the existing microchannel evaporator design approach -- which com ...

Improved head and hearing protection is required for aircraft maintainers working on a carrier flight deck during launch and recovery operations. Legacy Flight Deck Cranials are inadequate in many aspects including hearing protection, impact protection, cleaning, comfort, and compatibility with night vision devices (NVDs) and with chemical, biological, and radiological (CBR) equipment. In this p ...

An integrating nephelometer is proposed that can be deployed on a variety of platforms including powered aircraft and towed vehicles. The design allows air to pass freely through the sample cell with no restrictions. A sampling rate of up to 100 hz will allow for aerosol flux measurements. The light scattering coefficient will be measured at multiple wavelengths to provide angstrom coefficien ...

We propose a high performance, automated, and novel framework to behind-the-wall imaging and target discrimination. Our system has two paths: 1) stationary target detection using SAR images; 2) moving target detection using ISAR images. For the SAR imaging part, we first propose to apply high performance algorithm to form SAR images. Second, since feature extraction is the key component for a succ ...

Ceramic matrix composites (CMCs) are desirable for high-performance aircraft engines due to their excellent strength-to-weight ratio and their ability to withstand high temperatures. However, CMCs are expensive to machine due to their low thermal conductivity, high hardness, and abrasiveness. Creare’s innovation is a novel Laser-Assisted Machining (LAM) system for high-performance machining of ...

The primary objective of this program is the investigation of new approaches to achieve well-dispersed ultrahigh loading of carbon nanotubes (CNTs) in structural resins for advanced composites. “Well-dispersed” means CNTs that are optimally dispersed for achieving desired properties like strength, modulus, toughness, and thermal conductivity, rather than uniformly dispersed CNTs. Phase I will ...

In order to improve the performance of speaker identification, voiceprint matching, and speech recognition in noisy and clutter (multiple-speaker cocktail party) environment, we need an integrated approach. In this project, we propose a novel approach that addresses this challenging problem in a unified framework. First, we propose to apply microphone(s) to acquire speech signals. Single microphon ...

The use of ceramic matrix composite (CMC) materials in aero-engine hot-section components has grown substantially over recent decades. Attributes that make these materials attractive to aero-engine designers include their lower specific weight, higher creep resistance, higher thermoshock resistance and higher specific strength over a large temperature range in comparison to superalloys and greate ...

The U.S. Navy requires a swaging tool for attaching arresting gear purchase cable terminals on ship. Swaging is a well understood process, and there are many suppliers of adequately powerful machines. However, these machines are too large and cumbersome to be used in the shipboard environment. Creare proposes to develop a high power density swaging machine that is lightweight, portable, and whi ...
