The aging of insulating materials can be estimated by an electrical breakdown occurring in electrical components so that the relationship between lifetime, failure probability and reliability of electrical components may be studied using the life models in high voltage cables networks. In last decades with attention to higher features as electrical, thermal, mechanical characteristic, widely cr...
evaluation of mechanical and electrical properties of agricultural products plays an important role in equipment design and optimizing post-harvest operations. among the crops, tomato and its products are the major processing industries in the world and its economic importance is increasing. considering the importance of the quality and various post harvesting uses of tomato, the evaluation of ...
Electrical injuries due to high-tension voltage (>1000 volts) cause destruction at the point of contact with massive necrosis of deeper structures such as muscles, vessels and nerves. Rhabdomyolysis due to massive breakdown of skeletal muscles may lead to acute renal failure secondary to myoglobinuria. The study was undertaken to observe the correlation of renal complications with extent and pr...
Insufficient electrical endurance of equipment and insulation failure against overvoltage is one of the most effective reasons for failure the power line. Lightening, switching or other disruptive parameters can cause line outage or distribution substation failure. There are different devices used to improve the safety, reliability, and power quality of the system. Surge arresters are one of t...
This paper examines the potential failure mechanisms that can damage modern lowvoltage CMOS devices and their relationship to electrical testing. Failure mechanisms such as electrostatic discharge (ESD), CMOS latch-up, and transistor gate oxide degradation can occur as a result of electrical over-voltage stress (EOS). In this paper, EOS due to electrical testing is examined and an experiment is...
Smart, electronic textiles are often exposed to tensile stress which can lead to fracture of the interwoven conducting yarns. In this study, a model is proposed to relate the extensibility of the conducting yarns to the weaving pattern of the textile – in particular to the thickness and pitch of the textile yarns. The model is validated by simultaneous mechanical and electrical tests on bare ya...
Implantable devices have become a readily available option for patients with heart failure. Not only do these patients develop bradycardia and ventricular tachycardia, but their ventricular dysfunction can often improve with cardiac resynchronization therapy. However, this is a complex and rapidly developing clinical science for which the physician chooses techniques and selects patients on the...
