We propose an ear recognition system based on 2D ear images which includes three stages: ear enrollment, feature extraction, and ear recognition. Ear enrollment includes ear detection and ear normalization. The ear detection approach based on improved Adaboost algorithm detects the ear part under complex background using two steps: offline cascaded classifier training and online ear detection. ...

in order to study the effects of sowing date and plant density on forage yield and some morphological characteristics of corn, an experiment was conducted in gorgon research station in 2008. in this experiment two sowing date (18 april and 21 june) and six plant densities (25000, 45000, 65000, 85000, 105000, and 125000 plant per hectare) were evaluated in form of factorial experiment (2×6) with...

marginal zone lymphoma (mzl) accounts for between 5% and 17% of all non-hodgkin lymphomas (nhl). w e reported a rare case of marginal zone lymphoma presenting with bilateral ear erythema and swelling. the case was a 79-year-old man who suffered from progressive bilateral ear erythema and swelling since 2 years ago. physical examination was remarkable for erythmatous, edematous and non-tender au...

in this study, generation of the transient evoked ooacoustic emissions in human ear has been simulated using a new electroacoustic model. the method of state variables was adopted to calculate the auditory model, and numerical integration methods have been used to solve differential equations in matlab. simulation results have been compared with the real data. in this study, latency curves, fre...

Teratomas are tumors originated from mature or immature tissues. Teratomas are made up of one embryonic layer or all three embryonic layers (endoderm, mesoderm, or ectoderm). Herein we report a 41-year-old man who presented with vertigo, vomiting, and tinnitus. After physical examination, laboratory evaluation and performing computed tomography, cholesteatoma was diagnosed, however, during radi...
