Laser Technology Inc. (LTI) proposes a Phase II SBIR research project to further develop a Compact Shearography System, Analysis Method and Software for micro-crack detection in concrete. There is an urgent need to detect and characterize fine cracks in concrete that form because of various damage mechanisms including alkali-silicate reaction, delayed ettringite formation or frost damage. Fine s ...

A nondestructive evaluation method is proposed for imaging in-roadway sensors, anticipated to allow them to be located and evaluated in-situ. The techniques uses innovative step frequency GPR hardware together with new data collection and data processing methods to provide high-resolution images of in-roadway sensor features. Recent work by the proposed research team has already demonstrated im ...

Development of the basic EMAT based transverse rail defect detector has progressed toward finished form, as envisioned in the original solicitation. This modification is intended to produce a demonstratable version of a 2-rail detection system with automated signal interpertation. The objectives of this work are to: a. Further develop the system into a functioning 2-rail detection system, as ori ...

This research is aimed at developing a dialogue-based intelligent tutoring system, called Automated Tutoring Environment for Command or ATEC, to provide deliberate practice designed to improve battlefield command reasoning. It automates the Army ResearchInstitute classroom training program, Think Like a Commander (TLAC), through use of a dialogue management capability from the AutoTutor system, ...

ImageCorp, Inc. and its subcontractor M-Vision, Inc. propose to design and conduct a feasibility study of a machine vision system dedicated to the automatic analysis of the drivers¿ glancing direction. This system will be able to determine the beginning and end of the glancing activity in the video sequence, indexed by the subject (functional area of interest), duration, and direction of glance. ...

In order to remain competitive in today's global marketplace, U.S. manufacturers are constantly striving to hold tighter and tighter tolerances on the parts that they produce. What this means is that the manufacturer needs to better control the machines that they use, and in order to do that they need an instrument that can quickly and easily characterize the geometric properties of the machines ...

The goal of this project is to develop a multi-channel, real-time data acquisition, storage, and analysis system for acoustic emissions (AE). The proposed digital recorder will provide 12 independent channels of input with each channel supporting acquisition, storage, and processing of up to 20,000 AE events at a 10 MHz sampling rate. Our architectural approach will exploit the inherent parallel ...

The Federal Highway Administration has developed a suite of traffic simulation models to assist state, local, and consulting engineers to plan roads and traffic control improvements. Training for the models has traditionally been instructor-led, costly (particularly from the state and local government perspective), and limited in accessibility (subject to availability of instructors). With CORSI ...

The bonded resistance strain gage has made possible a varety of force sensing transducers, commonly known as "load cells." Widely used types of load cells include the column, the bending beam, the ring, the circular plat and the shear web. To instrument the anchor pins used in heavy truck air braking systems, STRAINSERT will utilize proven research and evaluation techniques implemented during th ...
