Resource-constrained embedded and mobile devices are becoming increasingly common. Cyber foraging, which allows such devices to offload computation to less resource-constrained surrogate machines, enables new and interesting applications for these devices. In this paper we describe a surrogate infrastructure based on virtual machine technology that allows(More)
DNA looping mediated by the Lac repressor is an archetypal test case for modeling protein and DNA flexibility. Understanding looping is fundamental to quantitative descriptions of gene expression. Systematic analysis of LacI•DNA looping was carried out using a landscape of DNA constructs with lac operators bracketing an A-tract bend, produced by varying(More)
We are building a wide area surrogate computing platform , called WASCo, that allows users to dynamically locate, allocate, and exploit resources on surrogate computers spread around the Internet. WASCo allows clients to install and run arbitrary code on surrogates. Uses of WASCo include offloading energy-intensive operations from energy-constrained(More)
Water making is the process of embedding data called a watermark into a multimedia object such that watermark can be detected or extracted later to make an assertion about the object. Earlier techniques based on spatial and frequency domain had the problems of a poor fidelity especially with higher payloads of watermark image. Unsatisfactory value of Peak(More)
The continuum-rod model has emerged as an efficient tool to describe the long-length-scale structural-deformations of DNA which are critical to understanding the nature of many biological processes such as gene expression. However, a significant challenge in continuum-mechanics-based modeling of DNA is to estimate its constitutive law, which follows from(More)
Digital Watermarking provides techniques to hide watermarks into digital content to protect it from illegal copy or reproduction. The prevalent techniques of digital watermarking in spatial domain cause the watermarked image to loose its image quality termed as Robustness and fidelity. Several techniques have been devised to optimize the Robustness and(More)
—Efficient and economic energy storage, if implemented in the current power infrastructure on a large scale, could bring about some of the greatest changes in the power industry in decades. Additionally, energy storage would improve the reliability and dynamic stability of the power system by providing stable, abundant energy reserves that require little(More)
