We examined the utility of a newly developed perceived air pollution (PAP) scale and of a modeled air pollution (MAP) scale derived from it for predicting previously observed birth outcomes of pregnant women enrolled following September 11, 2001. Women reported their home and work locations in the four weeks after September 11, 2001 and the PAP at each site on a four-point scale designed for th...

We first consider a cyclic φ-contraction map on a reflexive Banach space X and provide a positive answer to a question raised by Al-Thagafi and Shahzad on the existence of best proximity points for cyclic φ-contraction maps in reflexive Banach spaces in one of their works 2009 . In the second part of the paper, we will discuss the existence of best proximity points in the framework of more gene...

This paper investigates the existence, enumeration and asymptotic performance of self-dual and LCD double circulant codes over Galois rings of characteristic p and order p with p and odd prime. When p ≡ 3 (mod 4), we give an algorithm to construct a duality preserving bijective Gray map from such a Galois ring to Z p2 . Using random coding, we obtain families of asymptotically good self-dual an...

Let F be a field, let V = F, and let A : V → V a linear map. The polynomial P (x) = det(x1I+x2A+x3A ) does not depend on A but only on its characteristic polynomial χ(X). A law of composition ⊕ : V ×V → V is defined and it induces an Abelian group law on FP 2 \ P(0). The cubic P(0) is irreducible if and only if χ is irreducible in F[X], and in this case the group law ⊕ is cyclic.

6D SLAM (Simultaneous Localization and Mapping) or 6D Concurrent Localization and Mapping of mobile robots considers six degrees of freedom for the robot pose, namely, the x, y and z coordinates and the roll, yaw and pitch angles. In previous work we presented our scan matching based 6D SLAM approach [10–12,16], where scan matching is based on the well known iterative closest point (ICP) algori...

A new method is proposed for refining the calibration of a light striping system including a projective transformation between the image plane of the camera and the plane of the laser sheet, and also the direction of the scanning with respect to the plane of the laser sheet. The refinement is obtained through weighted least squares matching of multiple profile maps acquired from different viewp...

We analyze the residual errors for Wang-Sheeley-Arge (WSA) solar wind speed forecasts as a function of photospheric magnetic field expansion factor (fp) and minimum separation angle (d) in photosphere between footpoints open lines nearest coronal hole boundary. find map are systematic when examined fp d. use these error maps to apply corrections model speeds. test this correction approach using...

The inability to answer proximity queries efficiently for spaces of dimension d > 2 has led to the study of approximation to proximity problems. Several techniques have been proposed to address different approximate proximity problems. In this paper, we present a new and unified approach to proximity searching, which provides efficient solutions for several problems: spherical range queries, id...

genes (genetic heterogeneity). Mapping of the DHSt and FP genes7,9 now allows us to address this problem by means of a linkage analysis. Genomic DNA was obtained from each member of a pedigree described elsewhere.9 Linkage analysis was performed using 8 microsatellite markers (D16S511, D16S3037, D16S520, D16S498, D16S3074, D16S3026, D16S3121) from the chromosome 16 region where we have previous...
