We propose to develop an innovative, compact ultrafast high brightness laser source, broadly tunable in the infrared for vibrationally-resolved infrared microscopy and other applications. By passive Kerr lens mode-locking of a novel diode-pumped tunable Cr:LiSAF laser, 100fs pulses will be generated at 100 MHZ repetition rate with an average power of 1W. An optical parametric oscillator (OPO) pump ...

In response to the increasing demand for better understanding of the manufacturing processes and the machining systems, a new testing standard--ASME B5.54 and a family of new testing instruments have been developed for evaluating the performances of a variety of CNC machining centers. Because of the advancement and versatility of the new instruments, test data are being collected at a much higher ...

The storage photostimulable phosphor (SPP) technique has been demonstrated to be sensitive to ionization radiation. It is especially suited for detecting alpha particles since the efficiency is practically 100%. In addition to being able to quantify total ionization deposited in a SPP sensor, it also captures the radiation source distribution information in a digital image which can be readily ana ...

More than 20 years after the advent of balloon angioplasty restenosis remains a major health risk and cost burden. Success in animal trials and treatments in other non-malignant lesions using radiotherapy has established a new branch of medical science, intravascular brachytherapy (IVB) in treating restenosis. In just over 6 years since the first application, there are today more than 500,000 ...

Intelligent Automation, Incorporated is developing a new innovative approach to concurrent product-process development. The resulting system will also allow integrated development of production planning and scheduling, including external supplier integration. Our approach is based on the paradigm of autonomous agents. The work herein proposed focuses on improvements and extensions to the "Intel ...

Critical issues associated with the design of a rugged, compact "real time" sampling system using photoconductive switches as the signal generator and sample will be investigated. The design concept is based upon an optoelectronic equivalent time sampling principle developed by the Principal Investigator. It involves first the phase locking of the temporal waveform to be measured to the optical pu ...

The research proposed herein in intended to solve two problems, namely (1) to define a specification framework for access control policies that enables policy composition for both centralized and distributed systems in a precise and systematic manner, and (2) to explore the impact of different security architectures on policy composition. Although most commercial systems support applications that ...

We propose to improve the calculation of seismic event locations at regional distances in areas without calibrated station corrections by replacing the conventional travel-time table with those travel times that are generated (during the locationcomputation) from an existing program that uses 3-D ray-tracing through an inhomogeneous earth model. Regional location accuracy will be improved by calc ...

Algal toxins can cause mass mortality of wild and farmed fish, contaminate shellfish beds and cause human illnesses from consumption of these products. Dinoflagellates are widely recognized to be the primary algae associated with toxic red tide blooms. Once established, harmful algal blooms typically are mono-specific. The bio-optical "fingerprint" of the bloom, related to the specific pigment com ...

Fire fighter burn injuries continue to be a frequent problem despite significant advances in protective clothing. A reason for this is the buildup of moisture in fire fighting garments as a result of sweating or fire fighting activities. This buildup of moisture increases the heat transfer through the garment and can result in scald burn injuries as the water is quickly heated. Currently, there is ...
