Pseudo-Polar Based Estimation of Large Translations Rotations and Scalings in Images (2005)

One of the major challenges related to image registration is the estimation of large motions without prior knowledge. This paper presents a Fourier based approach that estimates large translation, scale and rotation motions. The algorithm uses the pseudo-polar transform to achieve substantial improved approximations of the polor and log-polar Fourier transforms of an image. Thus, rotation and scale changes are reduced to translations which are estimated using phase correlation. By utilizing the pseudo-polar grid we increase the performance (accuracy, speed, robustness) of the registration algorithms. Scales up to 4 and arbitrary rotation angles can be robustly recovered, compared to a maximum scaling of 2 recovered by the current state-of-the-art algorithms. The algorithm utilizes only 1D FFT calculations whose overall complexity is significantly lower than prior works. Experimental results demosntrate the applicability of these algorithms.

Visible spectrum (645 nm) transverse electric field laser operation of InP quantum dots coupled to tensile strained In0.46Ga0.54P quantum wells (2004)

Data are presented that demonstrate the continuous wave room-temperature transverse-electric field (TE) visible-spectrum (645 nm) heterostructure laser operation of single-layer compressively strained 3.75 monolayer equivalent InP quantum dots (QDs) coupled to 60 Å wide tensile-strained In0.46Ga0.54P quantum wells (QWs). The simple stripe geometry (200 μm×4 μm) InP QD+InGaP QW heterostructure laser is capable of high performance despite the coupling of two competing recombination systems. The InP QD+InGaP QW laser exhibits low threshold (∼31 mA), high quantum efficiency (72%, ∼1.38 mW/mA), a relatively high characteristic temperature T0 of 69 K, and a shift in wavelength at temperature of 0.19 nm/°C.
Asynchronous Multi-Radar Tracking Fusion with Converted Measurements (2022)

In tracking applications, multiple radars used to observe target motion usually work asynchronously due to different sampling rates and initial sampling time instants, and the fusion time instant at the fusion center can be designated arbitrarily. In this paper, the estimation fusion problem for target tracking with asynchronous multi-rate multi-radar measurements is investigated. Two asynchronous fusion algorithms are proposed, i.e., batch time-aligned asynchronous fusion with unbiased converted measurements and sequential linear minimum mean square error (LMMSE) asynchronous fusion with converted measurements. The batch time-aligned asynchronous fusion algorithm is suboptimal because of the correlation between measurement error covariance and measurement itself. The sequential LMMSE asynchronous fusion algorithm is theoretically optimal in the sense of minimizing the mean square error within the set of all linear estimators. Numerical examples are provided to demonstrate the effectiveness of the proposed two asynchronous fusion algorithms.
Characterisation of leaky wave antennas constructed from solid rectangular waveguides with a dipole frequency selective surface sidewall (1999)

Modelled and measured results for solid rectangular waveguides with longitudinal frequency selective surface (FSS) inserts are presented. Measured results confirm the accuracy of the solid guide model. An FSS sidewall in a rectangular waveguide is shown to behave as a leaky wave antenna (LWA).
Immunologic assessment of regional lymph node histology in relation to survival in head and neck carcinoma (1976)

Histologic material from 84 cases of squamous cell carcinoma of head and neck regions was studied by double blind retrospective analysis. Sections of lymph nodes draining the tumors were examined microscopically to assess the morphologic pattern of response. Patients whose lymph nodes demonstrated active immunologic responses in the form of expanded inner cortices or increased numbers of germinal centers had 5-year survival rates significantly greater than those patients whose regional lymph nodes showed an unstimulated pattern. None of the patients whose lymph nodes showed the depleted pattern survived 5 years. These correlations were independent of the stage or grade of the tumor. Metastases occurred much more frequently in patients having regional nodes showing an unstimulated or depleted pattern than in those whose regional nodes showed evidence of immunologic activity. The data support the concept of a relationship between immunologic activity, progression of neoplasia, and survival. Morphologic assessment of immunologic activity in lymph nodes draining malignant tumors appear to be of significant value in the predicting survival.
Analyzing milestones in smoking cessation: Illustration in a nicotine patch trial in adult smokers. (2006)

Tests of addiction treatments seldom reveal where treatment exercises its effect (i.e., promoting initial abstinence, preventing lapses, and/or impeding progression from lapse to relapse). The authors illustrate analyses distinguishing effects on these milestones in a randomized trial of high-dose nicotine patch (35 mg; n = 188) versus placebo (n = 136) in adult smokers, who used electronic diaries to monitor smoking in real time during 5 weeks of treatment. High-dose patch promoted initial abstinence (hazard ratio [HR] = 1.3) and decreased the risk of lapsing among those who achieved abstinence (HR = 1.6). The biggest effect of treatment was to prevent progression to relapse among those who had lapsed (HR = 7.1). Analysis of effects by milestones may enhance understanding of cessation treatments and their mechanisms of action.

Structure‐ReactivityCorrelations of Excited Statesof Perfluorinated Compounds:A Time Resolved Raman Study (1999)

This paper reports the TR 3 spectral studies on perfluorinated organic systems with the objective to understand the influence of perfluorination on the excited states. We have recorded the TR 3 spectra and Raman excitation profiles of the triplet excited states of decafluorobenzophenone and fluoranil. It is found that the influence of perfluorination is more pronounced in the triplet excited state than the ground state and thus leads to enhanced reactivity for perfluorinated compounds through larger structural distortions.

N-delta and differential average signal processors: detailing of their signal and noise response (1993)

A detailed and complete derivation of the impulse response (and transfer function) for the most commonly used charge-coupled-device (CCD) output signal processing techniques is presented. A basic mathematical model is discussed for 2- delta double sampling and is then generalized to n-sample systems. The method is adapted to show how the impulse response for the differential averaging technique is derived. The relationship between n- delta and differential average is illustrated mathematically. Simple signal gain derivations using the previously derived impulse responses are given. White, 1/f, and 1/f/sup 2/ noise power are discussed in light of the derivation. Graphs illustrating the noise dependence of both n- delta and differential average processor types are included.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

Genetic variation of twenty autosomal STR loci and evaluate the importance of these loci for forensic genetic purposes (2014)

The aim of this study was of twofold. One was to determine the genetic structure of Iraq population and the second objective of the study was to evaluate the importance of these loci for forensic genetic purposes. FTA&reg; Technology (FTA&trade; paper DNA extraction) utilized to extract DNA. Twenty (20) STR loci and Amelogenin), including D3S1358, D13S317, Penta E, D16S539, D18S51, D2S1338, CSF1PO, Penta D, THO1, vWA, D21S11, D7S820, TPOX, D8S1179, FGA, D2S1338, D5S818, D6S1043, D12S391, D19S433 and Amelogenin amplified by using power plex21&reg; kit. Polymerase chain reaction (PCR) products detected by genetic analyzer 3730xL then data analyzed by PowerStatsV1.2. Based on the allelic frequencies, several statistical parameters of genetic and forensic efficiency have been estimated. This includes the homozygosity and heterozygosity, effective number of alleles (n), the polymorphism information content (PIC), the power of discrimination (DP) and the power of exclusion (PE). The power of discrimination values for all tested loci was from 75 to 96%; therefore, those loci can be safely used to establish a DNA-based database for Iraq population. The high PIC values of the selected markers confirm their usefulness for genetic polymorphism studies and linkage mapping programs in human as well. The mean heterozygosity observed, is expected to have mean PIC values across the 20 loci which were 0.77, 0.81 and 0.78, respectively, indicating high gene diversity. &nbsp; Key words: &nbsp;Autosomal STR, genetic variation, Iraq, statistical parameters.

Flow-Based Fast Multichannel Nonnegative Matrix Factorization for Blind Source Separation (2022)

This paper describes a blind source separation method for multichannel audio signals, called NF-FastMNMF, based on the integration of the normalizing flow (NF) into the multichannel nonnegative matrix factorization with jointly-diagonalizable spatial covariance matrices, a.k.a. FastMNMF. Whereas the NF of flow-based independent vector analysis, called NF-IVA, acts as the demixing matrices to transform an M-channel mixture into M independent sources, the NF of NF- FastMNMF acts as the diagonalization matrices to transform an M- channel mixture into a spatially-independent M-channel mixture represented as a weighted sum of N source images. This diagonalization enables the NF, which has been used only for determined separation because of its bijective nature, to be applicable to non-determined separation. NF-FastMNMF has time-varying diagonalization matrices that are potentially better at handling dynamical data variation than the time-invariant ones in FastMNMF. To have an NF with richer expression capability, the dimension-wise scalings using diagonal matrices originally used in NF-IVA are replaced with linear transformations using upper triangular matrices; in both cases, the diagonal and upper triangular matrices are estimated by neural networks. The evaluation shows that NF-FastMNMF performs well for both determined and non-determined separations of multiple speech utterances by stationary or non-stationary speakers from a noisy reverberant mixture.
On n-type finite state acceptors (1964)

Certain properties of three variants of the multi-tape automata of Rabin and Scott are proved. Closure properties of the defined sets of n-tuples are found, and the nature of projections of the defined sets of n-tuples on one coordinate is studied. Some necessary conditions for acceptance are derived, and a characterization of the sets of n-tuples defined by non-deterministic n-tape automata is found. The results in the paper generalize and supplement the results of Rabin and Scott.
Application of asymptotic expansions for maximum likelihood estimators errors to gravitational waves from binary mergers: The single interferometer case (2010)

In this paper we apply to gravitational waves (GW) from the inspiral phase of binary systems a recently derived frequentist methodology to calculate analytically the error for a maximum likelihood estimate of physical parameters. We use expansions of the covariance and the bias of a maximum likelihood estimate in terms of inverse powers of the signal-to-noise ration (SNR)s where the square root of the first order in the covariance expansion is the Cramer Rao lower bound (CRLB). We evaluate the expansions, for the first time, for GW signals in noises of GW interferometers. The examples are limited to a single, optimally oriented, interferometer. We also compare the error estimates using the first two orders of the expansions with existing numerical Monte Carlo simulations. The first two orders of the covariance allow us to get error predictions closer to what is observed in numerical simulations than the CRLB. The methodology also predicts a necessary SNR to approximate the error with the CRLB and provides new insight on the relationship between waveform properties, SNR, dimension of the parameter space and estimation errors. For example the timing match filtering can achieve the CRLB only if the SNR is larger than the Kurtosis of the gravitational wave spectrum and the necessary SNR is much larger if other physical parameters are also unknown.
An evaluation of the taxonomy of Propionibacterium (1968)

The object of this study was to reevaluate speciation of Propionibacterium by using numerical taxonomy. Fifty-six cultures representing eight species were studied. Thirty-eight morphological and physiological features were employed in the calculation of matching coefficients which were used to sort the cultures into groups. The results suggest a need for species consolidation; for example, Propionibacterium shermanii could appropriately become P. freudenreichii var. shermanii. Close resemblances were found between P. rubrum, P. peterssonii, and P. jensenii. Propionibacterium arabinosum and P. pentosaceum formed another mutually similar group. Further studies using additional cultural, physiological, serological, genetic, and phage host-range characteristics should be instituted to establish an improved classification of propionibacteria.
Adaptive Control for Flexible Space Structures with Measurement Noise (1987)

This paper addresses the problem of measurement noise in the design of adaptive controllers for large space structures. It is shown by simulation that although the well known fix based on introducing leakage terms in the adaptive law is successful in eliminating drift in the adaptive gains, the overall control demand remains unrealistically high. In order to reduce the control demand, it is necessary to attenuate the noise by introducing filters at key positions in the adaptive configuration. However, arbitrary choice and placement of noise filters is dangerous since lags tend to cause instabilities in the adaptation loop. This phenomenon is verified by simulation. The main result of this paper is a general theory for introducing noise filters into the adaptive controller so as to effectively suppress measurement noise, while insuring global stability of the adaptive algorithm. This result utilizes the new concept of a branch filter which allows filtering of the output error without introducing phase lag into the adaptive loop. The effectiveness of the proposed methods are demonstrated by simulation on an adaptive payload articulation control for a Space Station model.
Structural and Mechanical Properties Changes of Ethylene‐α‐olefin Copolymer Blends Induced by Thermal Treatments and Composition (2004)

Abstract Summary: Blends of single‐site catalysed ethylene‐ α ‐butene (C 4 VLDPE) and ethylene‐ α ‐octene (C 8 VLDPE) copolymers were prepared by melt extrusion. The phase morphology, thermal and mechanical properties of the blends have been investigated by differential scanning calorimetry (DSC), scanning electron microscopy (SEM), tensile test and dynamic mechanical analysis (DMA). Depending on the composition and thermal history, significant differences in structure and behaviour were found. It was also found that some degree of co‐crystallization occurred for quenched blends; whereas most of the oven slowly cooled blends showed two well‐defined melting peaks, indicating that the slow cooling favoured partial segregation of the fractions with different degrees of branching to form two morphologies. Moreover, SEM revealed morphology of the thinner crystals distributed in‐between the thicker sheaf‐like crystals for the slowly cooled blends with 20–50% C 8 VLDPE. Therefore, the synergism in mechanical properties for the blends with 20–50% C 8 VLDPE is due to a combination of larger crystal size, more complete phase separation and interfacial interaction produced by the segregation effect of the slow cooling treatment. DMA studies showed that the storage modulus increased as the addition of C 8 VLDPE and modulus for the slowly cooled blends are about twice those measured for the quenched ones, indicating higher stiffness of the blends. The smooth shift of β relaxation temperature with addition of C 8 VLDPE for both sets of blends confirmed the miscibility in the amorphous phase.

ADGEN: a system for automated sensitivity analysis of predictive models (1986)

A system that can automatically enhance computer codes with a sensitivity calculation capability is presented. With this new system, named ADGEN, rapid and cost-effective calculation of sensitivities can be performed in any FORTRAN code for all input data or parameters. The resulting sensitivities can be used in performance assessment studies related to licensing or interactions with the public to systematically and quantitatively prove the relative importance of each of the system parameters in calculating the final performance results. A general procedure calling for the systematic use of sensitivities in assessment studies is presented. The procedure can be used in modelling and model validation studies to avoid ''over modelling,'' in site characterization planning to avoid ''over collection of data,'' and in performance assessment to determine the uncertainties on the final calculated results. The added capability to formally perform the inverse problem, i.e., to determine the input data or parameters on which to focus additional research or analysis effort in order to improve the uncertainty of the final results, is also discussed.

Cyber-Physical Security Evaluation in Manufacturing Systems with a Bayesian Game Model (2020)

Cyber-physical security has been taken more seriously recently in manufacturing systems because of highly increasing integration of cyber and network systems with physical production known as cyber-physical manufacturing systems (CPMS). This paper presents a novel proactive approach to forecast the interrelation of attackers and cyber-physical manufacturing systems to suggest a proper defense strategy to the system managerial. In this research, the zero-sum game payoff function developed in our previous studies is transformed into an epistemic type Bayesian game that addresses uncertainties on types of players. The risk preference behavior also is considered as a characteristic of different types of players and to form the Bayesian utility function. Finally, a numerical example is analyzed with a structured method by developing the Bayesian game, computing Bayes-Nash equilibria, and finding quantal response equilibrium. This approach enables managers to decide a proper defense strategy in advance of experiencing cyber-physical dilemma when there are not enough previous data.

Edouard Glissant: The Poetics of Risk (2011)

While there is an attempt to install Edouard Glissant as a literary patriarch after his death, we should not forget his interest in a poetics of risk that was tied to Michel Leiris's fascination with primitive rituals in general and the bullfight in particular. Glissant's well-known rejection of systems of organization is profoundly connected to the power of this primal drama in which the subject is always off balance, identity always thrown into question in the face of the fierce charge of external reality.
