In this paper a new authentication system using Finger Back Knuckle Surface is examined. This paper is intended to propose an effectual method for personal authentication using Finger Back Knuckle Surface. This method take advantage of the less number of features extracted from the Finger Back Knuckle Surface and the Angular geometric analysis is done to mine the distinguishable feature informa...

Fingernail deformity is common, yet current methods used to define cosmetic appearance following trauma are mainly descriptive. In order quantify the of fingernail, we developed Oxford Appearance Score using a three stage iterative process. The score has five components marked as binary outcomes composed nail shape, adherence, eponychial appearance, surface and presence split. first stage, two ...

The spontaneous non-ischaemic blue finger is a rare and benign disorder, characterized by purple discoloration of a finger, with complete resolution. This article reports the case of a woman of 88 years, which after a few hours of stay in the emergency department developed without associated trauma, a purplish color of the 3rd finger of the right hand, with a palpable pulse and without temperat...

The fat-finger problem has emerged to a routine problem when interacting with especially small touch devices. Thereby, the target is smaller than the size of the finger contact area and interactions may result in incorrect input. Developers tried to respond to this and created new interfaces and tools. In this paper, I would like to present four approaches to address the problem. The stylus is ...

Introduction: Lateral condensation effectiveness may be influenced by the gutta-percha and finger spreader taper used during root canal obturation. Objective: To evaluate the penetration ability of finger spreader into simulated root canals prepared using MTwo rotary system and filled with different gutta-percha and finger spreader tapers. Material and methods: Resin blocks with curved root can...

Finger vein recognition is a promising biometric recognition due to its some advantages. For a finger vein recognition system, feature extraction is a critical step for the final recognition. In our previous work, we proposed Personalized Best Bit Map(PBBM) which selected the stable bits from LBP. Although PBBM achieve a better performance, it still contains some useless bits for recognition. I...

Understanding morphological instabilities at soft interfaces is important in a variety of diverse problems, such as adhesion/debonding in polymer films and biological cells, friction, cavitation, and patterning. Non-specific interactions of electromagnetic origin play an important role in these instabilities. Spontaneous surface patterns appear in soft solid films that are in contact proximity ...
