Mashhad City, according to the latest official statistics of the country is the second populated city after Tehran and is the biggest metropolis in the east of Iran. Considering the rapid growth of the population over the last three decades, the city’s development area has been extended, significantly. This significant expansion has impacted natural lands on suburb and even some parts e.g. rang...

We investigate surfaces which interpolate given boundary curves. We show that the discrete bilinearly blended Coons patch can be defined as the solution of a linear system. With the goal of producing better shape than the Coons patch, this idea is generalized, resulting in a new method based on a blend of variational principles. We show that no single blend of variational principles can produce...

Biometrics authentication o,ers many advantages over conventional authentication systems that rely on possessions or special knowledge. With conventional technology, often the mere possession of an employee ID card is proof of ID, while a password potentially can be used by large groups of colleagues for long times without change. The fact that biometrics authentication is non-repudiable (hard ...

In this paper we use the nudged elastic band technique from computational chemistry to investigate sampled highdimensional data from a natural image database. We randomly sample 8×8 and 9×9 high-contrast patches of natural images and create a density estimator believed as a Morse function. By the Morse function we build one-dimensional cell complexes from the sampled data. Using one-dimensional...

this paper aims at finding the long term coupled effect of high temperature and constant high relative humidity on the corrosion rehabilitated patches of chloride contaminated steel reinforced concrete. this paper is an extension of previous research in which the authors experimentally corroborated re-corrosion in the repaired reinforced concrete (rc) patches in the form of macro-cells. in prev...

A lot of groups and individual developers work on improving the Linux kernel. Many innovative new features are developed all the time. The best and smoothest way to distribute and maintain new kernel features is to incorporate them into the standard mainline source tree. This involves a review process and some standard conventions. Unfortunately actually getting innovative new features through ...

The main goal of this paper is to exhibit a simple method to create surface patches that contain given curves as geodesics, when reparameterized by arclength. The method is based on the observation that a curve which lies on a surface is a geodesic (up to parametrization) if and only if its tangent and acceleration vectors are coplanar with the surface normal along the curve. This observation r...

White patches are a worrying finding for patients, in particular with concern arising about the possibility of the lesions being or becoming cancerous. This paper looks at some of the common white patches that present and relevant considerations in deciding on a management plan for them.
