|
 | We propose new nonparametric statistical tests to identify whether each element in a sequence of independent multivariate observations is drawn from a common probability distribution or if some distributional change has occurred over the course of the sequence. Each test is formulated using matching techniques based on distances between observations. These tests are capable of detecting changes of quite general nature, and, unlike most similar tests, they require no distribution ... |

| This work analyzed the spatial distribution of violent events as constructed from a content analysis of open source news reports. Data on 112 variables was available for 45 neighborhoods. The small sample limited the analysis to those 32 variables with at least four observations. The statistical analysis was done both for the original measures of event counts by neighborhood, and for binary variables that indicated the presence of events. Test ... |

M A Ainslie; C A van Moll; J Janmaat; TNO Defence Security and Safety The Hague (Netherlands)
|
 | A new empirical formula for the absorption of sound in seawater is derived. The starting point of this investigation is the formula proposed by Ainslie and McColm for attenuation due to the boron and magnesium relaxations. Constants in the expression are treated as parameters to be determined. Since this is a nonlinear inverse problem, a global search is used to find the parameter setting that yields the best fit to ... |

| The Navy's open architecture framework is intended to promote reuse and reduce costs. This paper focuses on exploiting open architecture principles to reduce testing effort and costs in cases in which the requirements and code for a subsystem have not been changed, but the code is running on new hardware and/or new operating systems due to a technology advancement upgrade. This situation is common in Navy and DoD contexts such ... |

J. K. Su; M. K. Griffin; S. M. Hsu; S. Orloff; C. A. Upham; MASSACHUSETTS INST OF TECH LEXINGTON LINCOLN LAB
|
| Hyperspectral imaging (HSI) sensors provide imagery with hundreds of spectral bands, typically covering VNIR and/or SWIR wavelengths. This high spectral resolution offers promise for many applications, but it also produces enormous volumes of data, which may be problematic for storage and transmission. Lossy compression may therefore be necessary, but application performance degradation that results from compression is of concern. This report documents results for a spectral-spatial lossy compression scheme and ... |

Sokol Saliu; Dritan Poci; Nils Edvardsson; CHALMERS UNIV OF TECHNOLOGY GOETEBORG (SWEDEN) LINDHOLMEN COLLEGE
|
| Based on alpha-stable distributional modelling, we have proposed a set of parametric measures to analyze long-term heart rate variability(HRV). The set, in difference from standard measures, accommodates premature beats in the HRV analysis. It preserves the structure of standard measures, redefines many of them and includes new measures. The rationale of the method was demonstrated by simulations. We found that the standard measures SDANN and SDNNIndex were strongly correlated to ... |

| The goal of this research is to improve the ultrasonic diagnosis of breast lesions so that physicians can objectively and reliably identify those lesions requiring biopsy. This capability would reduce the large numbers (estimated as 70%) of negative breast-lesion biopsies, avoiding unneeded patient trauma and reducing biopsy-related expenses. A series of ultrasonic parameters was defined to quantitatively describe the ultrasonic backscatter and attenuation of lesions and to quantify their boundary ... |

| Mars, RC6, Rijndael, Serpent and Twofish were selected as finalists for the Advanced Encryption Standard (AES). To evaluate the finalists' suitability as random number generators, empirical statistical testing is commonly employed. Although it is widely believed that these five algorithms are indeed random, randomness testing was conducted to show that there is empirical evidence supporting this belief. In this paper, NIST reports on the studies that were conducted on the ... |
