A new method was devised for measuring the pH of a concrete surface by pHBOY-P2 with a piece of filter paper by extracting the pH value from concrete. This is a simple and inexpensive method that does not damage the concrete building, and is easy to apply on concrete samples for monitoring. By using the method mentioned above, a drastic decrease of the pH value of concrete bridges and buildings...

Wide dynamic range images (WDRIs) are needed for capturing scenes which include drastic lighting changes. This paper presents a method to widen the dynamic range of a camera by using a reflective liquid crystal. The system consists of a camera and a reflective liquid crystal placed in front of the camera. By controlling the attenuation ratio of the liquid crystal, scene radiance of each pixel i...

Cooperative dysregulation of gene sequence and expression may contribute to cancer formation and progression. The Cancer Genome Atlas (TCGA) Network recently catalogued gene sequence and expression data for a collection of glioblastoma multiforme (GBM) tumors. We developed an automated, model-free method to rapidly and exhaustively examine the correlation among somatic mutation and gene express...

We propose an efficient online real-time solution for singlecamera 3–D tracking of rigid objects that can handle large camera displacements, drastic aspect changes, and partial occlusions. While the offline camera registration problem can be considered as essentially solved, robust online tracking remains an open issue because many real-time algorithms described in the literature still lack rob...

دشت بستان­ آباد یکی از دشت­ های استان آذربایجان شرقی می­باشد که در شمال غرب ایران واقع شده است. در این دشت، آب زیرزمینی بخش مهمی از مصارف آب شرب و کشاورزی را تأمین می­نماید و به همین دلیل حفاظت از این منابع در برابر عوامل آلاینده امری مهم تلقی می­گردد. بدین منظور جهت ارزیابی آسیب­پذیری آبخوان در برابر عوامل آلاینده از دو روش وزن­دهی DRASTIC و SINTACS در محیط نرم­افزار GIS استفاده شد. در این راس...
