 | The Integrated Multi-Modal RF Sensing (IMMRF) effort performed basic research to examine key parameters of integrated multi-modal RF sensor design and algorithm development. A statistical framework for the program was developed, which ensured the overall statistical validity of the approaches. Dynamic waveform design for agile RF sensing, enhanced detection capabilities, and optimized tracking performance was investigated. Approaches were developed for using multiple, spatially distributed, adaptive multi-modal sensors for multiple target ... |

| There is a general consensus that 3D reference models can be used to isolate effects of wave propagation and thus help in improving characterization of seismic sources. Advances in computation and numerical method have made it possible to capture increasingly broadband, full wave generation and propagation in 3D earth models. The main objectives of this project are to construct hierarchical, multi-grid (resolution) joint P and S velocity models and the ... |

| Improvements to the current Middle East wave-speed model with full waveforms require confidence in sources and recordings, along with a methodology to iteratively improve the model and reduce its minimum period. The mismatch between recordings of seismic waves traversing the region from Tibet to the Red Sea compared to synthetics from the current iteration model is the principal metric in improving the current wave-speed model. After the sources were evaluated, ... |

| We proposed efficient techniques for passive detection and localization of emitters of low probability of intercept signals. These are the generalized likelihood ration test (GLRT) detector and the maximum likelihood estimator (MLE). We derived the theoretical bounds for the localization variance, the Cramer-Rao lower bound (CRLB), and showed that the MLE attains the bounds. We further investigated the problems of optimal sensor configuration, knowledge aided geo-location design as well as ... |

| During the first year of the funding period 04/01/2011 until present, we have devoted the majority of our efforts towards obtaining pairs of mutant and functionally corrected telomerase-immortalized (hTERT) Fanconi anemia patient-derived fibroblast lines. Specifically, we have focused on the following FA complementation groups: FA-A, FA-G, and FA-D2. For the FA-D2 complementation group, we have obtained two pairs of mutant and corrected lines from collaborators. We have subsequently hTERT-immortalized these ... |

| Improving current Middle East wave speed models with full waveforms required confidence in sources and recordings, along with a methodology to iteratively improve models and reduce the minimum period of the waveforms used. A large, well recorded subset of 201 events (1997 2007) was reinterpreted through a direct comparison between data and synthetics based upon a centroid moment tensor inversion. Initial evaluations were done using a 1D reference model at ... |

| ASTM D2435 (2000) allows for both Teflon coated stacked rings and wire reinforced membranes to be used as confinement methods in direct simple shear (DSS) testing of soils. Although stacked rings were developed over 50 years ago, wire reinforced membranes have been used almost exclusively in practice. Over the past 10 years, however, stacked rings have become more popular and are now the dominant confinement system sold and used in ... |

| In the mid-1980s the Jamestown Verrazzano Bridge was built in Rhode Island spanning the west passage of Narragansett Bay. The bridge was to be founded primarily on pre-stressed concrete piles acting as friction piles. A test pile program was conducted at the beginning of construction and the measured capacity of the piles was significantly lower than predicted values. This led to significant delays in construction, cost overruns, and ultimately led ... |

| Efforts to update current wave speed models of the Middle East require a thoroughly tested database of sources and recordings. Recordings of seismic waves traversing the region from Tibet to the Red Sea will be the principal metric in guiding improvements to the current wave speed model. Precise characterizations of the earthquakes, specifically depths and faulting mechanisms, are essential to avoid mapping source errors into the refined wave speed model. ... |

| In an effort toward improving current seismic-velocity models for the Middle East, the initial Step of building a high-quality database of recordings from well characterized sources is essential. This high-quality database of recordings, or broadband waveforms, encompassing the region from the Mediterranean to the eastern edge of Tibet, will be the primary measure for evaluation and improvement in the iterative, waveform-based, adjoint-inversion process. Adjoint inversions, as with any waveform-based method, ... |

| Authors:
Praveen Peddi; Lisa C. DiPippo; RHODE ISLAND UNIV KINGSTON
|
| This paper describes a replication algorithm for distributed real-time object-oriented databases in a static environment. All data requirements are specified a priori, and the algorithm creates replication transactions that copy remote data to a local site in order to guarantee that every data request reads temporally valid data. The algorithm conditions are proven to be necessary and sufficient for providing this guarantee. Test results indicate that under most conditions, this ... |

| The Unified Modeling language provides a robust set of tools for modeling software systems. However, these tools do not directly address the requirements of real-time systems. Many real-time systems require the specification of data that has strict timing constraints. This paper presents a UML package for specifying real-time objects called RT-Object. The constructs in the package are based on the objects of the RTSORAC "Real-Time Semantic Objects Relationships And Constraints" ... |

|
| The preparation of N-phenyl-substituted poly(isocyanide) (N-phi-PIM) utilizing a Ni(II) catalyst in methanol yields a brown material having a number average molecular weight of about 2000. Analysis of this "as prepared" polymer indicates that a rigid rod structure is present in the derived solid. Dissolution of this "as prepared" N-phi-PIM in halocarbon solvents or THF apparently leads to unraveling of the helical polymer with subsequent aggregation and precipitation of materials that ... |

| Authors:
A. Madsen; E. Andrieu; H. Ghonem; RHODE ISLAND UNIV KINGSTON
|
| This paper describes the evolution of precipitation at a selected aging temperature of 593 C in a new silicon-bearing near-alpha titanium alloy designated Ti-1100. This particular aging temperature was chosen to simulate the aging process occurring during service in a gas turbine engine. Over-aging results in the formation of silicide precipitates along the alpha platelet boundaries and the formation of Ti3Al distributed homogeneously throughout the matrix. The overall hardness response ... |

| This paper examines the vertical coherence and structure of Gulf Stream meanders in the region just downstream of Cape Hatteras where the Stream flows down across the continental slope. Here the meanders are known to exhibit rapid spatial growth, yet the amplitudes are still small enough so that the convoluted paths associated with eddy formation may be avoided. |

| Theoretical estimates are developed for a variety of mechanisms for the deterioration of icebergs in the open ocean environment. Although all the estimates are of an elementary nature, primarily algebraic correlations, the estimates seem to be in good agreement with the limited experimental data available. Formulas are given for computing the static stability of an iceberg from observations of the exposed shape. Simple theoretical estimates are made for the response ... |

| Temperature sensitivity of shear strength as defined in this study increases with increasing shear strength. The ratio of temperature sensitivity to shear strength is approx 0.0075C to the -1 power and is the same for different clays. Over the range of strengths of interest in this study the effect of temperature is such that strengths at 4C would be about 10% higher than at 20C. Because of natural heterogeneities and ... |

|
| In general, these three groups of marine mammals have retrained their own characteristic modes of communication with little convergence. Their communication is limited and fashioned by the physical and biological characteristics of the environment. These families communicate in water and in air, and the effects of the media on communication must be known to understand signal adaptation. Visual and acoustic communication are important in both media, depending on the amount ... |
