Surface transitions of the semi-infinite Potts model I: the high bulk temperature regime

We propose a rigorous approach of Semi-Infinite lattice systems illustrated with the study of surface transitions of the semi-infinite Potts model

Current Trends in Spectral Reflectance Imaging Techniques: A Qualitative Approach to the Investigation and Documentation of Building Materials

Preservationists utilize many techniques to evaluate sites and monuments, and continually strive for increasing levels of accuracy. Today researchers are able to virtually reconstruct objects, buildings and entire sites through the use of digital-imaging technology, and many of these same techniques are being adapted to provide non-destructive documentation and material analysis. Increasing portability and decreasing cost of digital-imaging equipment promises to yield myriad avenues for investigation and provide further opportunities for accurate documentation. In consultation with imaging specialists and Columbia University faculty, a range of imaging techniques have been selected which represent potentially viable methods for non-destructive material analysis. Techniques of particular interest involve data collection within the visible and infrared regions of the electromagnetic spectrum, including thermographic-IR imaging, multispectral imaging, and hyperspectral imaging. By examining the materials associated with historic structures (e.g. stone, metal, brick, terra cotta, concrete and wood) and imaging technologies currently available, it is the goal of this research project to create a model for determining appropriate imaging techniques necessary to decipher construction materials. In doing so, this paper attempts to qualitatively examine the feasibility of using spectral-imaging for in-situ exterior survey and assessment of building facades, where it can be important to quickly, remotely and non-destructively distinguish among original construction, biological growth, paint, and other colored building materials

Cervical Radiculopathy: A Case Report

There is currently little evidence to determine which conservative treatment approach is best for the management of patients with cervical radiculopathy; however, there is evidence these patients benefit from a multi-treatment approach. The purpose of this case is to describe the physical therapy management of a patient with cervical radiculopathy. Physical therapy diagnosis was based on the patient’s physical signs and symptoms as well as meeting three of the four criteria of the clinical prediction rule which is used to identify patients with cervical radiculopathy. Results from the examination and evaluation were consistent with the magnetic resonance imaging findings. Physical therapy treatment included patient education, therapeutic exercise, manual traction, and manual therapy. Patient’s pain improved from a 9/10 to 0/10 and Neck Disability Index score improved from 46% disability to 0% disability from initial examination to discharge. Following a multi-treatment approach that included patient education, therapeutic exercise, and manual therapy techniques, this patient with cervical radiculopathy experienced decreased pain, increased cervical mobility, improved posture, and was able to return to full-time work duties and prior level of function

Surface transitions of the semi-infinite Potts model II: the low bulk temperature regime

We consider the semi-infinite (q)-state Potts model. We prove, for large (q), the existence of a first order surface phase transition between the ordered phase and the the so-called "new low temperature phase" predicted in \cite{Li}, in which the bulk is ordered whereas the surface is disordered

Application of a Cumulative Method for Car Borders Specification in Image

The paper deals with low-level car detection methods in images. The car detection is an integral part of all intelligent car cruise systems. This article describes the method for suppression of the edges produced by classical edge\'s operators, based on application of the cumulative method. The designed method uses the non-stationary property of the picture background in time-realizations of the image signal
