In this paper, static and dynamic behavior of a varactor of a micro-phase shifter under DC, step DC and AC voltages and effects of the residual stress on the phase diagram have been studied. By presenting a mathematical modeling, Galerkin-based step by step linearization method (SSLM) and Galerkin-based reduced order model have been used to solve the governing static and dynamic equations, resp...

We investigate the self-assembly of symmetric disk-coil molecules using Monte Carlo simulations in the NPT ensemble. Our molecules are composed of a planar disk (head) that is covalently bonded to a single coil (tail), and can be regarded as disk-coil copolymers. For this system, we observe a variety of phases depending on the temperature and the effective interactions between the disk and coil...

To speak about fundamental measure theory obliges us to mention dimensional crossover. This feature, inherent to the systems themselves, was incorporated in the theory almost from the beginning. Although at first it was thought to be a consistency check for the theory, it rapidly became its fundamental pillar, thus becoming the only density functional theory which possesses such a property. It ...

Traditional memory systems based on memory technologies such as DRAM are fast approaching their cost and power limits. Alternative memory technologies such as Phase Change Memory (PCM) are being widely researched as a scalable, costand power-efficient alternative for DRAM. However, a PCM memory cell has a limited endurance of 10− 10 writes, resulting in an ideal lifetime of only a few years whi...

Previous researches have shown most programs have phase behavior. We would like to take advantage of the phase behavior of applications to dynamically reconfigure an embedded platform in order to achieve more energy efficiency and performance. In this study, we first outline some aspects of the phase behavior with emphasis also on the influence of the Operating System (OS). We developed a tool ...

The level of activity of many animals including humans rises and falls with a period of ~ 24 hours. The intrinsic biological oscillator that gives rise to this circadian oscillation is driven by a molecular feedback loop with an approximately 24 hour cycle period and is influenced by the environment, most notably the light:dark cycle. In addition to the circadian oscillations, behavior of many ...
