There are several method for forming bulk material, such as forging, rolling and extrusion. Every of these methods have advantages and dis-advantages of their selves. Forging process is one of the most common of them that include a die, press and in some case heater with controlling system, and has a special place in automotive, military and aerospace industries due uniformity of the final prod...

An iteration optimization approach integrating backpropagation neural network (BPNN) with genetic algorithm (GA) is proposed. The main idea of the approach is that a BPNN model is first developed and trained using fewer learning samples, then the trained BPNN model is solved using GA in the feasible region to search the model optimum. The result of verification conducted based on this optimum i...

Superplastic behaviour of Mg-alloy AZ31 was investigated to clarify the possibility of its use for superplastic forming (SPF) and to accurately evaluate material characteristics under a biaxial stress by utilizing a multi-dome test. The material characteristics were evaluated under three different superplastic temperatures, 643, 673, and 703 K in order to determine the most suitable superplasti...

INTRODUCTION Patients with mandible deformity may die, as a result of airway management failures. The awake nasal fiberoptic intubation is known as the optimum intubation method, in the mentioned patients, although, in several cases, fiberoptic intubation fails. CASE PRESENTATION The present case discusses a patient with severe deformity of mandible that was admitted for correction with free-...

Magnetic angle sensors detect the angular position of a permanent magnet attached to a rotating shaft. The magnet is polarized diametrically to the rotation axis. No soft magnetic flux guides are present. The semiconductor die is placed on and orthogonal to the rotation axis. There are two kinds of systems: (i) perpendicular systems detect the field components perpendicular to the rotation axis...

Raw material inventory is a major element of the working capital of many organizations. Hence its proper control is crucial for the profitability of the organization and development of surrounding communities. The sudden unavailability of raw material inventory for production can be a great operational disturbance which results in delivery delays, customer dissatisfaction and loss of market sha...

On ramasse un blesse (We pick up the injured) On transporte un agonisant (We carry the moribund) On hospitalise un mourant. (We hospitalise the dying). Professor M Arnaud Doctors worldwide are becoming increasingly aware of the need for transporting some patients under medical supervision and optimum conditions by using mobile medical or paramedical units. With proper treatment and resuscitativ...

Superplastic forming (SPF) is conducted in a heated, pressurized die where direct monitoring of critical SPF parameters is extremely difficult. Numerical models provide a critical means of tracking the forming process, allowing the applied gas pressure to be adjusted to maintain optimum SPF behavior throughout the forming process. This paper describes how the MARC finite element code was used t...

The Network-on-Chip (NoC) is an enabling technology to integrate large numbers of embedded cores on a single die. Traditional multi-core designs based on the NoC paradigm suffer from high latency and power dissipation due to the inherent multi-hop nature of communication. The performance of NoC fabrics can be significantly enhanced by introducing long-range, low power, and high-bandwidth single...
