It is once again presented and discussed in this paper that the method of distortion calibration based on 2D Direct Linear Transformation (DLT) is easy and feasible. It is emphasized that it is fit for the creation of distortion model for solid-state cameras (CCD, CID, PSD) to compensate for the system errors of various image points. The application of the distortion model presented in this pap...

We report a new classification method for pyranose ring conformations called Best-fit, Four-Membered Plane (BFMP), which describes pyranose ring conformations based on reference planes defined by four atoms. The method is able to characterize all asymmetrical and symmetrical shapes of a pyran ring, is readily automated, easy to interpret, and maps trivially to IUPAC definitions. It also provide...

In this paper we present an easy estimation approach for solving non-standard GEEs based on global optimization methods. Our approach has the added advantage that it can be easily implemented using existing software, such as the subroutine nlminb in Splus, which also allows for the inclusion of constraints. To illustrate our approach, we fit a non-linear dose response model with constraints to ...

There are lots of condom brands, sizes, and pleasure-inducing gimmicks out there ? but it's not always easy to find which one will work best for you. When beginning to explore sexual intimacy, roadblocks like yours may arise, but the fact that you're dedicated to practicing safe sex despite this challenge is commendable. Just remember, even though it may take time and some trial and error to fi...

The conception of Mental Health is not easy to define although in practice there is a large common measure of agreement among investigators and practitioners in its ever-widening field of endeavour. Some regard it as a state of satisfactory balance between conscious judgment and unconscious drives, motives and desires; others as a readiness to fit into the environment and accept the responsibil...

The analysis of Fermi Large Area Telescope (LAT) gamma-ray data in a given Region Of Interest (RoI) usually consists performing binned log-likelihood fit order to determine the sky model that, after convolution with instrument response, best accounts for distribution observed counts. While tools are available perform such fit, it is not easy check goodness-of-fit. difficulty assessment data/mod...

In the context of a “beauty contest” coordination game (in which payoffs 1 depend on the quadratic distance of actions from an unobserved state variable and 2 from the average action) players choose how much costly attention to pay to vari3 ous informative signals. Each signal has an underlying accuracy (how precisely it 4 identifies the state) and a clarity (how easy it is to understand). The ...
