osteoid osteomata are rarely found in the distal phalanges of the hand. the usual presenting features are chronic pain, nail enlargement and increase in size of the terminal part of the digit. diagnosis is difficult but surgical excision is effective for treating the patients’pain. we reported this tumor in distal phalanx of the middle finger.
An artificial torso is a fundamental part of a humanoid robot for imitating human actions. In this paper, a prototype of CAUTO (CAssino hUmanoid TOrso) is presented. Its design is characterized by artificial vertebras actuated by cable-driven parallel manipulators. The design was conceived by looking at the complex system and functioning of the human torso, in order to develop a solution for ba...
Introduction: Hand and wrist stability are critical for optimal upper extremity function. Instability occurs when injury or a pathological condition alters balance, typically in the basketball players and handball players. Injury also can occur whenever the ligaments are subjected to tensile forces that exceed their physiological capacities. For example, thumb is stable in ext...
This chapter introduces the fundamentals of ARTIST (an acronym for Artificial Intelligence-aided Synthesis Tool). ARTIST is a prototype system for sound synthesis that allows composition of sounds thought of in terms of qualitative descriptions (e.g. words in English) and intuitive operations rather than low level computer programming. My research work is looking for (a) plausible strategies to...
In this paper, a new method of bandwidth estimation using variation of slot length on interdigital band pass filter has been presented using artificial neural networks for desired frequency range between 1.7—2.5 GHz. Interdigital filter is multifinger periodic structure which offers compact filter design space. An ANN model has been developed and tested for estimating the cut off frequency of b...
This paper presents an underactuated artificial hand intended for functional replacement of the natural hand in upper limb amputees. The natural hand has three basic functionalities: grasping, manipulation and exploration. To accomplish the goal of restoring these capabilities by implanting an artificial hand, two fundamental steps are necessary: to develop an artificial hand equipped with arti...
This paper reports on the second generation of the Pleated Pneumatic Artificial Muscle (PPAM) which has been developed to extend the life span of its first prototype. This type of artificial was developed to overcome dry friction and material deformation which is present in the widely used McKibben type of artificial muscle. The essence of the PPAM is its pleated membrane structure which enable...
Objective: To study of relationship between alopecia areata and finger print dermatoglyphic types in 100 patients with alopecia areata and in 100 controls. Methods: A case control analytical study was done on fingerprints of patients with alopecia areata. The control cases were older than 50 years old without any history of alopecia areata. Dermatoglyphical trials of total fingers were al...
background: to evaluate safety and efficacy of percutaneous release of trigger finger in multiple digits involvement in comparison with single digit involvement. method: a number of 100 patients (131 fingers) were treated by percutaneous release and divided into two groups: single digit (group a) and multiple digits (group b). they were followed up for one year. success rate, pain, complicat...
in this research, first, kinematic and dynamic equations of a 4-dof 3-link robotic finger are derived using denavit-hartenberg convention and lagrange’s formulation. to model the muscles, several springs and dampers are placed between the finger links. then, two advanced controllers, namely adaptive-robust and adaptive-neural, which can control the robotic finger in presence of parametric uncer...
