PROBLEM The homicide rate of taxicab-industry is 20 times greater than that of all workers. A NIOSH study showed that cities with taxicab-security cameras experienced significant reduction in taxicab driver homicides. METHODS Minimum technical requirements and a standard test protocol for taxicab-security cameras for effective taxicab-facial identification were determined. The study took more...

FACE TO FACE: FRANCO BELTRAMETTI AND JUDITH DANCIGER: A COUPLE OF TRANSLATORS
 In 1973 Franco Beltrametti, a Swiss author strictly connected to both the authors of Beat Generation and those Italian neo-avant-garde (Gruppo 63), published bilingual collection poems in English that he significantly titled Face face (Grosseteste, England). As stated book itself, versions are translations by hi...

  Background :Soft tissue profile can be widely different in various populations. Furthermore, this profile can be also continues to change throughout life. However, there are few studies that quantitatively evaluate the soft tissue profile in Iranian population. In order to determine normal reference values of facial parts in our populations, we aimed to measure standards for facial soft tissu...

BACKGROUND Oxygen supplementation through Hudson type face mask is frequently used in perioperative settings. Hudson mask is a variable rate performance device with the risk of rebreathing. Studies using capnography to find out an actual fraction of rebreathing in spontaneously breathing patients are not available. AIMS In this study, we analyzed the effects of different flow rates through Hu...

In this paper we study the problem of linearly equalizing the Multiple Input Multiple Output (MIMO) communications channels from an H∞ point of view. H∞ estimation theory has been recently introduced as a method for designing filters that have acceptable performance in the face of model uncertainty and lack of statistical information on the exogenous signals. In this paper we obtain a closed-fo...

In this paper, a kernel fuzzy discriminant analysis minimum distance-based approach for the classification of face images is proposed to deal with face classification problem (we call this method mdkfda/qr as an abbreviation). A superiority of the mdkfda/qr is its computational efficiency and can avoid the singularity. In the proposed method, the membership degree is incorporated into the defin...

The performance of ear recognition is influenced by pose variation. For the similar position of ear and profile face, a multimodal recognition method is proposed based on the feature fusion of ear and profile face information. A model for ear and profile face feature fusion and recognition is built. The Log-Gabor features of ear and profile face are first extracted separately, and two features ...
