This paper establishes formulas that can be used to bound the actual treatment eeect in any experimental study in which treatment assignment is random but subject compliance is imperfect. These formulas provide the tightest bounds on the average treatment eeect that can be inferred given the distribution of assignments, treatments, and responses. Our results reveal that even with high rates of ...

Synthetic aperture radar (SAR) is an active remote sensing tool operating in the microwave range of the electromagnetic spectrum. It uses the motion of the radar transmitter to synthesize an antenna aperture much larger than the actual antenna aperture in order to yield high spatial resolution radar images (Curlander & McDonough, 1991). It has been applied to military survey, terrain mapping, a...

background and objectives: although more than 90 percent of consumed water used in agricultural sector, water is the major limiting factor for agricultural development in iran. over the past few years increasing agricultural crop water productivity thorough deficit irrigation methods has been studied by agricultural researchers and planners. although lorestan province is one of the major produc...

Moreover, regarding the diagnosis of an infectious entity, we believe in the importance of the association of the serology and the clinical picture, considering that the isolated use of the serological method can yield false-positive results, including the cases where there is laboratory error. Therefore, we believe that the probability of a high antibody titer level is higher than the actual r...

This paper addresses the problem of evaluating the quality of handwritten signatures used for biometric authentication. It is shown that some signature samples yield significantly worse performance than other samples from the same person. Thus, the importance of good reference samples is emphasized. We also give some examples of features that are related to the signature stability and show that...

Two widely used statistical approaches to reconstructing past climate histories from climate 'proxy' data such as tree-rings, corals, and ice cores, are investigated using synthetic 'pseudoproxy' data derived from a simulation of forced climate changes over the past 1200 years. Our experiments suggest that both statistical approaches should yield reliable reconstructions of the true climate his...

This paper discusses some aspects of deconvolution of one-dimensional spectra in the framework of the Least Squares Method and presents a minimum variance regularization procedure. Covariance matrices are taken into account in every step. Fluctuation and artifacts, both in the deconvolved and regularized spectra, are related to the structure of the covariance matrices. The method is applied to ...

Hadron colliders can be an abundant source of heavy flavor quarks, but pose a challenge to isolate the physics signals from the high backgrounds. The upgraded CDF II detector, with its precise tracking capabilities and powerful trigger system, is well equipped for this task. The detector is described with an emphasis on actual performance and on techniques to maximize the heavy flavor yield. So...

WP-STXQRD-01 This white paper describes the implementation of the QR decomposition-based recursive least squares (RLS) algorithm on Altera StratixTM FPGAs. Coordinate Rotation by Digital Computer (CORDIC) operators can be efficiently time-shared to perform the QR decomposition while consuming minimal resources. Back substitution can then be performed on the embedded soft Nios processor by utili...

I discuss a novel technique for periodically extending by reflection an ordered series of phase-difference {xk.} to yield estimation of new frequency and time variances having improved longterm confidence and the same mean as the Allan variance. In addition, I describe a correction to a negative bias in the sample variance based on the actual number of observations in the measurements at long t...
