 | This report summarizes our research for the year January 2005 to Decenber 2005. We have developed multi-category classifiers based on seismic data to classify heavy-tracked, light-tracked, heavy-wheeled and light-wheeled ground vehicles. We focused on data collected in the normal terrain. We also developed fusion algorithms for type-1 and type-2 Fuzzy logic Rule-Based Classifiers (FL-RBCs) based on the Choquet Fuzzy Integral (CFI). We conducted experiments to evaluate the performance of the ... |

|
 | (U) THIS PAPER PROPOSES TO ESTABLISH FOOTPRINTS OF UNCERTAINTY FOR VEHICLE FEATURES THAT ARE USED IN SOCALLED TYPE-2 FUZZY LOGIC RULE BASED CLASSIFIERS. THE PAPER DESCRIBES THE DATA COLLECTION, AND A METHOD FOR GENERATING PROTOTYPES FROM THE DATA FROM WHEELED AND TRACK VEHICLES BY SEGMENTING EACH DATA RECORD INTO SHORT OVERLAPPING DATA BLOCKS. A FEATURE EXTRACTION IS DESCRIBED AS WELL AS THEIR STATICTICS. RECOMMENDED FOOTPRINTS OF UNCERTAINTY FOR EACH FEATURE ... |

|
| A summary of accomplishments on the grant, "Optics in Parallel Shared Memory Computing", over the period 7/1/93-10/31/97, is given. Accomplishments include the design of a parallel shared memory optical/electronic computer, and a centralized control algorithm for its processor-to-memory interconnection network. The grantee has also designed a volume-holographic shared memory system that can implement a set of parallel-access memory modules in a system comprising a single photorefractive crystal and 2 arrays ... |

|
| During the period 1 July 1985 - 30 June 1986, the research under Grant AFOSR-84-0181 has concentrated on various aspects of optical digital computing. We have continued detailed studies of a sequential optical parallel computing architecture whose wiring is implemented by computer-generated holograms. We have studied the implementation of various specialized processors such as cellular logic processors on this architecture and have examined high space-bandwidth interconnection holograms that serve this ... |

| During the period 1 July 1984 - 30 June 1985, the research under Grant AFOSR-84-0181 has concentrated on four major areas. First, work has continued on an experimental sequential optical binary parallel architecture that is constructed from an array of binary optical switching elements (NOR gates) with interconnections done by a computer-generated hologram. We are examining new binary array SLM's, high efficiency, high space-bandwidth product (SBWP) interconnection holograms, and compact ... |
