| Lanzhou is one of the major industrial cities in northwest China, the capital of Gansu Province, and located at a northwest-to-southeast oriented valley basin with elevation about 1,500-1,600-m. Due to topographic and meteorological characteristics, Lanzhou is one of the most polluted cities in China Meteorological conditions (low winds, stable stratification especially inversion), pollutant sources and sinks affect the air quality Lanzhou government carried out afforestation and pollutant-source reduction (closing several ... |

| The solubility of 3,4-dinitrotoluene (3,4-DNT) in natural filtered seawater with ionic strength = (0.1662, 0.3352, 0.5071, and 0.6820) mol/L and pure water was measured at temperatures ranging between (277 and 314) K. The solubility in seawater was lower than that in pure water. The average salting-out coefficient for 3,4-DNT was 0.13 L/mol, which is consistent with measurements for other isomers of dinitrotoluene. The salting-out coefficient did not show any significant ... |

|
| Four years after Congress directed the Department of Energy (DOE) to revamp its polygraph program, taking into account a 2003 National Academy of Sciences (NAS) report that questioned the scientific basis for the accuracy of polygraph testing, particularly when used to screen employees, DOE promulgated a regulation on October 30, 2006, that eliminated polygraph screening tests without specific cause. DOE said its counterintelligence evaluation policies were now consistent with existing ... |

Wei T. Soh; NAVAL POSTGRADUATE SCHOOL MONTEREY CA
|
| The multistatic radar offers many advantages over monostatic radar in certain applications, especially since the receiving stations may be located at covert and distant sites relative to the transmitting stations. Furthermore, continuous wave radars are relatively simple and inexpensive to employ and maintain. Hence, the impetus for developing a CW multistatic radar system for high-resolution imaging was conceived. This thesis is a proof of concept demonstration that a Doppler-only multistatic ... |

Starting from the weak-scatter far-field model we explain why this approximation it's a Fourier Transform. We investigate the scattering mechanisms from different surfaces. We also analyze and derived the expressions of the scatter from sphere. We briefly discuss the radon transform and why it's not a good approach to our problem. We investigate the ... |

Alban Simon; NAVAL POSTGRADUATE SCHOOL MONTEREY CA
|
| Non Linear Internal Waves (NLIW) are ubiquitous and appear wherever a proper combination of stratified water, current and bathymetry occur. In recent years, they have also been proven of primary interest for acoustic oceanography, since they are known to play an important role in sound speed fluctuations in shallow waters. The predictability of acoustic variability caused by these waves has been somewhat limited, and largely based on direct numerical simulation. ... |

S. Chiu; DEFENCE RESEARCH AND DEVELOPMENT CANADA OTTAWA (ONTARIO)
|
| It has been recognized that a two-aperture approach to ground moving target indication is sub-optimum and that target parameter estimation is often compromised by clutter interference or poor signal-to-clutter ratios. This paper investigates the Ground Moving Target Indication (GMTI) performance of several virtual channel concepts proposed for the RADARSAT-2 Moving Object Detection EXperiment (MODEX). These are capable of increasing the spatial diversity of RADARSAT-2 by exploiting its very flexible antenna ... |

| The problem addressed in this memorandum is nonstationary interference suppression in noise radar systems. Towards this aim, linear time-frequency (TF) transforms, short time Fourier transform (STFT) and local polynomial Fourier transform (LPFT) are used as a means of signal representation. The noise radar return signal is a wideband random signal occupying the whole TF plane, while the interference signal is well concentrated in the TF plane. This implies that the ... |

|
| The importance of tumor stroma in prostate cancer development and progression has been recognized through its stimulating effects on cancer cell growth, migration and angiogenesis. Our hypothesis was that the prostate cancer stroma is derived, at least in part, from mesenchymal stem cells (MSCs) that are proliferative, multipotent and self-renewing. Our objective was to demonstrate that cancer-derived stromal cells have characteristics of mesenchymal stem cells. Comparing primary cultures of stromal ... |

| Multi-robot systems provide system redundancy and enhanced capability versus single robot systems. Implementations of these systems are varied, each with specific design approaches geared towards an application domain. Some traditional single robot control architectures have been expanded for multi-robot systems, but these expansions predominantly focus on the addition of communication capabilities. Both design approaches are application specific and limit the generalizability of the system. This work presents a redesign of ... |

Shin-Tson Wu; UNIVERSITY OF CENTRAL FLORIDA ORLANDO SCHOOL OF OPTICS/CREOL
|
| For adaptive foveated imaging using a high resolution spatial light modulator (SLM), high birefringence and low viscosity LC mixtures are highly desirable. A higher birefringence enables a thinner liquid crystal layer to be used which results in a faster response time. Low viscosity is always favorable as it helps to reduce the SLM response time. For the thin-film-transistor (TFT)-addressed SLM, high resistivity is an extra requirement. In this report we ... |

We considered three distinct approaches, which involved: (1) Harnessing nanoparticles to heal cracks in layered composites; (2) Using microcapules to deliver nanoparticles to damaged coatings; (3) Exploiting photo-chemical reactions to create defect-free hierarchical structures. As we note below, our findings generated considerable interest in the scientific community. ... |

| A theoretical and experimental study of multimode operation regimes in quantum cascade lasers (QCLs) is presented. It is shown that the fast gain recovery of QCLs promotes two multimode regimes in QCLs: One is spatial hole burning (SHB), and the other one is related to the Risken-Nummedal-Graham-Haken (RNGH) instability predicted in the sixties. A model that can account for coherent phenomena, a saturable absorber and SHB is developed and studied ... |

| Planning and executing truly meaningful and affective PSYOP is a non-trivial process, especially in the asymmetric threat environments experienced during GWOT. PSYOP is an alchemy that combines elements of art, combat experience, science, linguistics, and religious and cultural expertise. The results of inadequate PSYOP planning, execution and lack of integration into full-spectrum operations, potentially has more detrimental effects on the psychological battlespace than the absence of PSYOP altogether.

| Considering the exploitation needs associated with the Synthetic Aperture Radar (SAR) applications involving moving and non-stationary targets, a fundamental spectral domain model for moving point and distribution of scatterers is presented. The approach is accurate as the spherical phase front is rigorously treated throughout the Doppler analysis. Due to the analytic nature of the model in range-Doppler plain, large squint-angle operations (e.g., SpotSAR) can be characterized. Furthermore, motion characteristics can ... |
