Nonlinear composite dielectrics can function as smart materials for stress control and field grading in all fields of electrical insulations. The percolation process is a significant issue of composite dielectrics. However, the classic percolation theory mainly deals with traditional composites in which the electrical parameters of both insulation matrix and conducting fillers are independent o...
The increasing development of smart materials, such as piezoelectric and shape memory alloys, has opened new opportunities for improving repair techniques. Particularly, active repairs, based on the converse piezoelectric effect, can increase the life of a structure by reducing the crack opening. A deep characterization of the electromechanical behavior of delaminated composite structures, acti...
نوآوری به عنوان یکی از مزیت های اصلی برای حیات شرکت ها محسوب می شود و همه ی سازمان ها برای بقا نیازمند ایده های نو و بدیع هستند. در تلاش برای رسیدن به نوآوری، اغلب سازمان ها بر پروژه های توسعه محصولات جدید از طریق تیم ها متکی هستند. امروزه، کار تیمی روشی پویا و پاسخگو برای دستیابی به پویایی مداوم محیط کسب و کار جهانی را فراهم می کند. تحقیقات در زمینه نوآوری بر اهمیت ایده سازی از طریق ترکیب، ادغ...
BACKGROUND Saline, the intravenous fluid most commonly administered to critically ill adults, contains a high chloride content, which may be associated with acute kidney injury and death. Whether using balanced crystalloids rather than saline decreases the risk of acute kidney injury and death among critically ill adults remains unknown. METHODS The Isotonic Solutions and Major Adverse Renal ...
The Weil descent attack, suggested by Frey, has been implemented by Gaudry, Hess and Smart (the so-called GHS attack), on elliptic curves over finite fields of characteristic two of composite degrees. The GHS attack has been extended by Galbraith to hyperelliptic curves of characteristic two. Recently, Diem presented a general treatment of GHS attack to hyperelliptic curves over finite fields o...
Magnetic nanoand microparticles have already found many important applications in various areas of biosciences, medicine, biotechnology, environmental technology etc. These smart materials exhibit different types of response to external magnetic field. In most cases they can be described as composite materials, where the magnetic properties are caused by the presence of iron oxides nanoor micro...
During the last years, many approaches have been proposed in order to address the issue of automated service composition. In this chapter, we discuss the so-called “Roman model”, in which services are abstracted as transition systems and the objective is to obtain a composite service that preserves a desired interaction, expressed as a (virtual) target service. We will also outline its deployme...
Segmented myriapod-like bodies may offer performance benefits over more common fixed body morphologies for ambulation. Here, the design of a segmented ambulatory microrobot with a flexible backbone is presented. A dynamic model describing the motion of the microrobot is used to determine body parameters. A three-segment microrobot was fabricated using the Smart Composite Microstructures process...
In the present investigation, an optimization algorithm inspired by nature is used for the fine-tuning of the parameters of a fuzzy controller used for the vibration suppression of a smart composite plate. More specifically, the particle swarm optimization method is chosen. This method is a population based optimization algorithm. It is a totally stochastic technique that simulates the movement...
