Abstract:It is proposed to develop and validate fast and robust algorithms and computer codes to simulate the processing of ceramic matrix composites. While the processing and parameters that control the efficient manufacturing of ceramic matrix composites can be studied experimentally, a validated… more
Abstract:A NEW TYPE OF COMPOSITE COLOR FILTER IS BEING DEVELOPED. THIS COLOR FILTER IS COMPOSED OF A POLYMER (METHYL METHACRYLATE) REINFORCED WITH COLORED OPTICAL GLASS AND HAS THE COMBINED PROPERTIES OF A GLASS SOLUTION AND GELATIN FILTER. GLASS COMPOSITION IS BEING DEVELOPED AND TECHNIQUES FOR PREPARING… more
Abstract:THERE IS A DEFINITE TREND IN EARLY CHILDHOOD EDUCATION AWAY FROM ROTE LEARNING METHODS TOWARD MORE CHILD DIRECTED, ACTIVITY-BASED LEARNING. AS CHILDREN ACT UPON AND CHANGE THE EXTERNAL ENVIRONMENT, THEY INTERNALLY CONSTRUCT KNOWLEDGE. CONSTRUCTIVISM STRESSES HANDS-ON INTERACTIVE LEARNING THROUGH… more
Abstract:We propose to design, implement and test the feasibility of a full body surface digitizing system to be used for anthropometric studies and design of protective equipment. Resolution, speed, coverage and accuracy of three dimensional (3D) optical surface scanning will be defined. A generic whole… more
Abstract:Accurate and timely assessment of battle damage may determine the survival of ship and crew. Without training, stress and high workload are known to produce specific types of judgment errors, including a narrowing of attention in which critical information may be overlooked, and an increased… more
Abstract:RESEARCHERS ARE COMPLETING A FEASIBILITY STUDY ON THE DEVELOPMENT AND PRACTICAL APPLICATION OF AN ADVANCED SOFTWARE PRODUCT DESIGNED FOR SOLVING SYSTEMS OF SIMULTANEOUS ALGEBRAIC EQUATIONS WHICH ARISE IN CONNECTION WITH THE P- AND HP-VERSIONS OF THE FINITE ELEMENT METHOD, UTILIZING MASSIVELY… more
Abstract:A DISPERSION AND COMPOSITE STRENGTHENING APPROACH INCORPORATING THE BENEFITS OF RAPID SOLIDIFICATION AND IN-SITU COMPOSITE FORMATION IS PROPOSED FOR THE DEVELOPMENT OF CREEP AND FATIGUE RESISTANT HIGH STRENGTH SOLDER ALLOYS AND COMPOSITES FOR ELECTRONICS PACKAGING APPLICATIONS . THE GOAL OF PHASE I… more
Abstract:This study will test the feasibility of alternative machine learning strategies for training an expert decision support computer program to automatically code social interaction processes. Collecting and analyzing interaction process data is difficult, time consuming, and expensive. Reliability and… more
Abstract:PRESENT TREATMENT OF RHEUMATOID ARTHRITIS IS PERFORMED BY SEVERAL METHODS, WHICH INCLUDE ANTI-INFLAMMATORY AGENTS, STEROIDS, IMMUNOSUPPRESSIVE AND CYTOTOXIC AGENTS, RADIATION TREATMENT BY BEAM METHOD, AND SURGERY. EACH METHOD HAS ITS DRAWBACKS. OF THESE METHODS, RADIATION BEAM TREATMENT HAS BEEN… more
Abstract:A new family of bioactive iron calcium phosphate glasses will be evaluated as thermoseeds for hyperthermia of cancers, especially bone tumors. Through appropriate heat treatment and atmosphere control, the Fe3+/Fe2+ ratio can be adjusted to achieve the desired magnetic hysteresis. The heat… more
Abstract:The objective of Phase I is to select a small number (3 - 5) of synthetic compounds with high biological activities as inhibitors of cancer cell aggregation, adhesion, detachment and spreading (motility). These compounds will be selected from a panel of 20 currently available synthetic structural… more
Abstract:A six-month effort is proposed to utilize the author's expertise in semiconductor laser diodes and fiber-optic technology to develop a design for a 50 to 100 watt fiber-coupled laser-diode source. A proprietary technique is described for achieving high power and high power density in the fiber which… more
Abstract:TELEPHONE NUMBER: (314) 429-7700 AWARDEE NUMBER: 1 R43 CA61390-01 The overall objective is to develop polysulfated carbohydrate derivatives that will inhibit the action of fibroblast growth factors (FGF). FGF's have been implicated in several human cancers both as angiogenic factors and as growth… more
Abstract:The overall objective is to develop a process to produce lactobionic acid that is free of oxidizing components. Lactobionic acid is an essential component of perfusion solutions used to preserve organs for transplantation (Sumimoto, 1990). It functions as an impermeant and calcium chelator as well… more
Abstract:RESEARCHERS ARE DESIGNING, IMPLEMENTING, AND TESTING THE FEASIBILITY OF A SOFTWARE MODULE TO TRANSLATE SPIRAL CT SCAN DATASETS OF DISCRETE OBJECTS INTO SOLID MATHEMATICAL MODELS (BOUNDARY REPRESENTATION-GEOMOD IN SDRC I-DEAS). THIS PROVES THE CONCEPT AND DEMONSTRTES THE FASIBILITY OF DIRECT INPUT… more
Abstract:There is no established non-contact method to quantify surface morphology or edema and objectively assess change resulting from facial reconstructive or cosmetic plastic surgery. We will develop and test a quantification technique based on a three dimensional, non-contact, optical range sensing… more
There are several categories such as “By Agency”, “By Year”, “By State” etc.
Select a checkbox within a category to refine your search results.
Each of your selections is listed in the “Narrow Search Filters” bar. You can uncheck these selections to remove them.
Search for Either Criteria
When you select multiple values within a category, the results will include values that match either of the selections.
For example, selecting “2005” and “2007” in the “By Year” category will display results that include either 2005 OR 2007 in the results.
Narrowing the Search Results
You can refine your search results across categories. To narrow down your results, select multiple values across different categories. The results will only include values that match the selections across the categories.
For example, selecting “2005” in the “By Year” category and “NASA” in the “By Agency” category will only display the results that contain both “2005” AND “NASA” in the results.
