In the event of a terrorist attack, the ability to measure the extent and location of the attack and rapidly notify first responders will be critical to saving lives. If the widespread use of cell phones could be harnessed with an ability to detect chemical threats and immediately notify authorities of the scope and location of the attack, public safety would be significantly enhanced. Synkera pro ...

THE PURPOSE OF THIS EFFORT IS TO STUDY THE FEASIBILITY OF AND, HOPEFULLY, VALIDATE THE USE OF TASK NETWORK MODELING TOSTUDY HUMAN FACTORS IN THE CONTROL ROOM. TASK NETWORK MODELING EXTENDS A HUMAN ENGINEERING TASK ANALYSIS INTO A COMPUTER MODEL. WE PROPOSE THAT PERTURBING THE INDIVIDUAL TASKS IN A TASK NETWORK MODEL IN A MANNER PREDICTED FROM CONTROL ROOM DESIGN CHANGES, TASK AUTOMATION, OR THE CO ...

RESIDUAL LIFETIME EVALUATION OF EXISTING NUCLEAR FACILITIES REQUIRES DETAILED INFORMATION REGARDING CONDITION OF CONTAINMENT AND SUPPORT STRUCTURES. CURRENT NONDESTRUCTIVE METHODS FOR SUBSURFACE EVALUATION OF REINFORCED CONCRETE USE COMPLEX EQUIPMENT AND RELY HEAVILY ON INTERPRETATION BY THE OPERATOR. A RESEARCH EFFORT IS PROPOSED TO EXAMINE THE USE OF COMPUTERIZED TOMOGRAPHIC IMAGING FOR LOCATING ...

IMPLEMENTATION OF AN INTEGRATED DETECTION SYSTEM FOR CONTAMINATION MONITORING OF RESPIRATORS HAS BEEN PROBLEMATIC. BECAUSE OF THE COMPLEX SURFACES, HAND MONITORING USING PORTABLE SURVEY INSTRUMENTATION HAS BEEN THE PREFERRED METHOD. HAND MONITORING IS COSTLY IN TIME AND OFTEN FAILS TO RELIABLY ACHIEVE A GIVEN DETECTION LIMIT BECAUSE OF VARIABLES SUCH AS SURVEY SPEED ANDDISTANCE FROM THE PROBE. THE ...

SIGNIFICANT CONSERVATISM IN MODERN SEISMIC PRA DERIVES FROM SIMPLIFICATIONS IN GROUND-MOTION CHARACTERIZATION AT THE INTERFACE OF SEISMIC HAZARD AND FRAGILITY METHODOLOGIES. THIS CONSERVATISM ARISES BECAUSE A SINGLE COMPOSITE-MAGNITUDE, BROAD-BAND, GROUND-MOTION SPECTRUM IS USED TO DERIVE FRAGILITY FUNCTIONS, WHEREAS THE MAJORITY OF MOTIONS CONTRIBUTING TO SITE HAZARD HAVE (LESS-DAMAGING) NARROW-B ...

Toxic Industrial Chemicals (TICs) are chemical substances that produce toxic effects if given in sufficient quantities and/or exposed for long durations. TICs are a great concern for the U.S. Department of Homeland Security (DHS) since it would be easier for terrorists to obtain and use than CAs. There are many commercially available handheld and personal gas monitors to monitor TICs. However, the ...

Marietta X-Ray, Inc (MXRI) and its subcontractor Rapiscan Laboratories, Inc. propose to develop a mobile non-intrusive prototype that can demonstrate the capability of inspecting a complete general-aviation aircraft for concealed contraband. Our solution utilizes an existing vehicle and manipulator coupled with an x-ray inspection system. The x-ray system is based on backscatter technology, which ...
