Knuckle pads occur from benign thickening of the skin, principally the epidermis, and are occasionally seen in children. Despite the name, knuckle pads most commonly overlie the proximal interphalangeal joints. They must be differentiated from a variety of other cutaneous abnormalities. There is no consistently effective treatment, but knuckle pads have been reported to resolve spontaneously in...

There are different biometric modalities used to identify person which includes palmprint, face, fingerprint, iris and hand geometry. Apart from these biometric modalities, finger knuckle print also used as one of the cost effective biometric identifier. Finger knuckle print is defined by the back side of fingers. On the back side of fingers there are three joints named as Metacarpophalangeal (...

Reducing weight of vehicle components will contribute towards overall weight reduction of a vehicle, lower its energy consumption demand, therefore, will improve its fuel efficiency. Material resources will be saved too. The objective of this research is reduce weight of an existing steering knuckle component of a local car model by applying shape optimization technique. A finite element modeli...

Biometric based personal authentication system has been receiving widespread interest in the area of research. In that, Identification of a person based on hand based biometrics has become a significant part in both research and real time application of personal authentication system. This paper proposes a new approach for personal authentication system based on Finger Back Knuckle Surface (FBK...

Finger knuckle-print biometric system has widely used in modern e-world. The region of interest is needed as the key for the feature extraction in a good biometric system. The symmetric discrete orthonormal stockwell transform provides the computational efficiency and multi-scale information of wavelet transforms, while providing texture features in terms of Fourier frequencies. It outperforms ...

A ball joint for an automobile steering system is a pivot component which is connected to knuckle and lower control arm. The manufacturing process for its caulking comprises spinning and deforming. In this study, the process was simulated by flexible multibody dynamics. The caulking was evaluated qualitatively through numerical analysis and inspecting a plastically deformed shape. The structura...

Biometric based Personal authentication is still active research problem due to various issues such as providing high accuracy, computationally less complex feature extraction method and fusion strategy of multiple feature information. In this work we propose a personal authentication system using one such hand based biometric trait, Finger Back Knuckle Surface (FBKS). The texture pattern produ...

Electronics Letters vol. 45, no. 20, September 2009 Personal Identification using Finger Knuckle Orientation Features Ajay Kumar, Yingbo Zhou This paper proposes a novel approach for personal identification using finger images which exploits the orientation features from the random knuckle lines using finite Radon transform. The feasibility of this approach is rigorously evaluated on a publical...
