ÐThis paper describes a method for partitioning 3D surface meshes into useful segments. The proposed method generalizes morphological watersheds, an image segmentation technique, to 3D surfaces. This surface segmentation uses the total curvature of the surface as an indication of region boundaries. The surface is segmented into patches, where each patch has a relatively consistent curvature thr...

In this work, we define the quality transfer problem and present an approach to tackle it: Given a low-quality image taken from a mobile phone, how could you enhance it in a visually plausible way to include additional details. Our approach is based on creating a temporal, gps-tagged high-quality image data-set by building a vehicular image capturing platform to autonomously capture high-qualit...

Breast cancer is becoming increasing pervasive, and its early detection is an important step in saving life of any patient. Mammography is an important tool in breast cancer diagnosis. The most important step here is classification of mammogram patch as normal-abnormal and benign-malignant. Texture of a breast in a mammogram patch plays a big role in these classifications. We propose a new feat...

An equivalent circuit model for predicting the frequency response of a square ring slot frequency selective surface (SRS-FSS) for normal incidence is described. The proposed FSS consists of an array of square patches centered within a wire grid. The presented circuit model is formed by the impedance of the wire grid that is parallel with the impedance of the patch array, also the mutual couplin...

A modified circular patch antenna design has been proposed in this paper, the bandwidth of this antenna is optimized using the genetic algorithm (GA) based on fuzzy decision-making. This design is simulated with HP HFSS Program that based on finite element method. This method is employed for analysis at the frequency band of 1.4 GHz- 2.6 GHz. It gives good impedance bandwidth of the order o...

Contraceptive patches have become a frequently used contraceptive method. We present a mathematical model that describes the serum concentration profiles of Norelgestromin (NGMN) and Ethinylestradiol (EE) released from the contraceptive patch Ortho Evra®. We propose a simple one-compartment model based on pharmacokinetics data reported in previous studies. The model assumes a time-dependent rel...

contact dermatitis is frequent skin pathology and eyelids are one of the more frequent locations of this pathology. the objective of the present work was to study the population distribution of periocular dermatitis, determine the allergens which most frequently indicate positive in patch tests and in provocative use tests, and analyse the clinical relevance of the positive tests. patients with...

Background: Various environmental factors can induce or exaggerate hand eczema. Objective: Evaluation of patch test results in hand eczema patients. Patients and Methods: In this descriptive study 100 patients with hand eczema referred to Loghman Hakim and Booali Hospital in Tehran underwent patch testing with 23 allergens obtained from Hermal company. Results: 240 positive reactions observed i...
