A major drawback in using bulk metallic glasses (BMGs) as structural materials is their extremely poor fatigue performance. One way to alleviate this problem is through the composite route, in which second phases are introduced into the glass to arrest crack growth. In this paper, the fatigue crack growth behavior of in situ reinforced BMGs with crystalline dendrites, which are tailored to impa...

As device dimensions are scaled down, single event transients (SET) are increasingly affecting the reliability of integrated circuits. An SET is a transient voltage perturbation caused by an energetic particle strike at the semiconductor. This work studies the applicability of bulk built in current sensors (bulk-BICS) for SET detection in deep-submicron technologies. The bulk-BICS detects the t...

Shear band spacing in Zr-based bulk metallic glasses (BMGs) under dynamic loads is found to vary with position and local strain rate in the indented region. To investigate the dependence of shear band evolution characteristics on local strain rate and normal stress, a micromechanical model based on momentum diffusion is proposed. The thermomechanical model takes into account the normal stress d...

in this paper, we present a simple method for preparation of graphene-zno nanocomposites (g-zno). the method is based on thermal treatment of the graphene oxide (go)/zno paste which reduces the graphene oxide into the graphene and leads to the formation of the g-zno nanocomposite. the structure, morphology and optical properties of synthesized nanocomposites are characterized with xrd, fesem, f...

This paper investigates the use of floating gate MOS devices for analog trimming. A floating gate MOSFET structure, in which tunneling occurs at the corners of a polysilicon slab, has been fabricated using a standard 1.2p.m n-well CMOS process. The analog storage performance of the floating gate is evaluated. A threedimensional device simulator, DAVINCI, is used to characterize the field enhanc...

nowadays, the application of floating breakwaters in small or recreational harbors has found more popularity. these types of breakwaters are more flexible in terms of design, configuration and especially installation compared with fixed breakwaters. in the current study, the performance of floating breakwater (fbs) under regular waves was studied using the physical modeling method. for the mode...

Floating point units form an important component of many reconfigurable computing applications. The creation of floating point units under a collection of area, latency, and throughput constraints is an important consideration for system designers. Given the range of possible tradeoffs, most commercial or academic floating point libraries for FPGAs provide a small fraction of possible floating ...
