In man, and in his arboreal ancestors, the skin on the palmar and plantar surfaces of the hands and feet has a peculiar linear formation which is believed to help the animal to obtain a firm grip, particularly on branches of trees. The structure was first described by Nehemiah Grew, in 1684, as composed of very numerous 'ridges of equal bigness and distance and everywhere running parallel with ...

The "ATD" angle is a dermatoglyphic trait formed by drawing lines between the triradii below the first and last digits and the most proximal triradius on the hypothenar region of the palm. This trait has been widely used in dermatoglyphic studies, but several researchers have questioned its utility, specifically whether or not it can be measured reliably. The purpose of this research was to exa...

Background: Due to the similar duration of development, finding dermatoglyphic patterns predict malocclusions can help a pediatric dentist attempt any necessary preventive and interceptive orthodontic therapies. Aim: To assess correlation between different with permanent molar relationships. Materials Methods: 300 children who are 14-16 years old completely erupted 2nd molars up occlusal table ...

Objective: To assess for any peculiar lip prints in relation to the shapes of individual, and determine most common print type among members biological families. Study Design: Descriptive study. Setting: Department Forensic Medicine & Toxicology, Women Medical Dental College, Abbottabad. Period: January 2018 June 2018. Material Methods: A total 216 individuals (father, mother, both children...

Due to increasing crime rate identification using biometrics has become an important field of research. When it is not possible to take snapshot, to read iris, to take finger prints etc then identification using gait may be proved an effective tool to identify a person. This paper presents a method which distinguishs between normal and abnormal gait. A person having abnormal gait may be categor...

Two different types of nanoparticles dissolved in organic solution, gold stabilized by n-alkanethiols and CdSe/ZnS stabilized by n-alkane-amine, adhere preferentially to the ridges of latent fingerprints; the gold deposits catalyze silver electroless deposition from "Silver Physical Developer" (Ag-PD), an aqueous solution containing silver colloids stabilized by cationic surfactants, to form da...

We present possible manifestations of octahedral and tetrahedral symmetries in nuclei. These symmetries are associated with the O h and T d double point groups. Both of them have very characteristic finger-prints in terms of the nucleonic level properties unique in the Fermionic universe. The tetrahedral symmetry leads to the four-fold degeneracies in the nucleonic spectra; it does not preserve...

Dermatoglyphic features, qualitative as well as quantitative, of finger and palm prints of 50 male I. C. D.-9 diagnosed catatonic schizophrenics and as many ethnically matched normal controls of the same sex were examined. Patients were found to differ from the control group in qualitative as well as quantitative features quite similar to the findings of the past three investigators. These diff...

Feature vector generation is an important step in biometric authentication. Biometric traits such as fingerprint, palmprint, iris, & finger-knuckle prints are rich in texture. This texture is unique and the feature vector extraction algorithm should correctly represent the texture pattern. In this paper a texture feature extraction methodology is proposed for iris and pamlprints. This method is...
