Effects Of Type And Thickness Of Dental Implant Coatings On Maximum Stress At The Interface Of Coating-Implant And Bone-Coating

Khalil Farhangdoust; Ali Banihashem; Ali Ghaneei

Volume -2, Issue 1 , July 2005, Pages 1-8

  Using ceramic coatings has increased in popularity due to their compatibility with bone, absence of the fibrous layer at the coating-implant interface, and the stronger coating-bone bonding. Among these coatings, hydroxyapatite (HA) and fluoroapatite (FA) are more popular. For the first time in this ...  Read More

Simulation Of Neurotransmitter Release At The Neuromuscular Junction

Mehrak Mahmoudi; Mohammad Jafar Abd Khodaei; Saeide Khatibirad

Volume -2, Issue 1 , July 2005, Pages 9-16

  A mathematical model is presented for simulation of neurotransmitter release in the synaptic cleft of a neuromuscular junction. Chaudhuri's model is improved by adding calcium diffusion effect on the neurotransmitter release. When an action potential occurs, the calcium channels on presynaptic membrane ...  Read More

Segmentation Of Mid-Brain Structures Based On Active Contours

Ladan Amini; Hamid Soltanian Zadeh; Caro Lucas; Masoume Giti

Volume -2, Issue 1 , July 2005, Pages 17-34

  Based on a discrete dynamic contour model, a method for segmentation of brain structures like thalamus and red nucleus from magnetic resonance images (MRI) is developed. A new method for solving common problems in extracting the discontinuous boundary of a structure from a low contrast image is presented. ...  Read More

Design And Prototyping Of An Ultrasonic Pulsed Doppler System For Blood Velocity Measurement In Vessels

Nima Hemati; Mohammad Javad Abolhassani

Volume -2, Issue 1 , July 2005, Pages 35-46

  Nowadays, various methods have been suggested to measure and monitor blood velocity variation in arteries and veins. Ultrasonic velocimetry is one of these methods, which is based on Doppler shift frequency measurement and the blood flow velocity calculation using Doppler shift signal. Using velocity-time ...  Read More

Optimal Design Of Beam Pattern Of Ultrasound Arrays Considering Sensitivity Of Transducer

Seyed Mahmoud Sakhaei; Ali Mahloojifar

Volume -2, Issue 1 , July 2005, Pages 47-56

  The beam pattern profile of an ultrasound array is of great importance in ultrasound imaging. This profile could be enhanced by weighting the elements of array. However, this technique will decreases the signal to noise ratio (S/N) and consequently the quality of the obtained image. In this study, the ...  Read More

A Model For Skill Movements Based On Self-Organized Control Strategy

Amir Homayoun Jafari; Seyed Mohammad Reza Hashemi Golpayegani; Farzad Towhidkhah; Ali Fallah

Volume -2, Issue 1 , July 2005, Pages 57-70

  A hierarchical structure model with three levels is presented for modeling motor control in skill movements. At each level, based on accuracy and quality of control, a specific controller is activated. At first level, control concepts are qualitative. The duty of the first level is to provide stability ...  Read More

A New Nonlinear Model Using Neural Networks For Generating Electrocardiogram Signals

Nader Jafarnia Dabanloo; Ahmad Ayatollahi; Vahid Jouhari Majd; Desmond Mclernon

Volume -2, Issue 1 , July 2005, Pages 71-80

  The generation of electrocardiogram (ECG) signals by using a mathematical model has recently been investigated. One of the applications of a dynamical model which can artificially produces an ECG signal is the easy assessment of diagnostic ECG signal processing devices. In addition, the model may be ...  Read More

Neural Network Modeling Of Electrically Stimulated Muscle Under Non-Isometric Conditions

Abbas Erfanian Omidvar

Volume -2, Issue 1 , July 2005, Pages 81-92

  This paper is concerned with developing a force-generating model of electrically stimulated muscle under non-isometric condition. Hill-based muscle models have been the most popular structure. This type of muscle model was constructed as a combination of different independent blocks (i.e., activation ...  Read More
