The nonequilibrium work relation allows for the calculation of equilibrium free energy differences between states based on the exponential average of accumulated work from irreversible transitions. Here, we compare two distinct approaches of calculating free energy surfaces from unidirectional single-molecule pulling experiments: the stiff spring approximation and the Hummer-Szabo method. First...

Autonomous and semi-autonomous full-sized ground vehicles are becoming increasingly important, particularly in military applications. Here we describe the instrumentation of one such vehicle, a 4-wheel drive Hummer, for autonomous robotic operation. Actuators for steering, brake, and throttle have been implemented on a commercially available Hummer. Control is provided by on-board and remote co...

PURPOSE A recently-developed assistive technology nicknamed "the Hummer" was investigated as a potential powered wheelchair controller for individuals with severe and multiple disabilities. System performance in a noisy environment was compared to that obtained with a commercial automatic speech recognition (ASR) system. METHOD A bi-hum driving protocol was developed to allow the Hummer to se...

101 THIS TWO-PART FEATURE BEGAN with a discussion of why unconventional left-turn alternatives hold promise for the relief of congested urban and suburban arterials. Part One, which was printed in the September 1998 issue of ITE Journal on pages 26–29, also described three unconventional alternatives—the median U-turn, the bowtie and the superstreet. This part discusses four more alternatives.

carnival is one of polyphonic word basis in mikhail bhaktin’s theory of dialogue logic. since “the carnival” is emerged from the mass celebrates in the middle ages, this element in language, is demonstrated with components, as humor, mockery and joking, rejecting the values of society, mixture of life and death, according to flesh and physical delight, social criticism, and in general, anything...

Heterogeneous and dirty data is abundant. It is stored under different, often opaque schemata, it represents identical real-world objects multiple times, causing duplicates, and it has missing values and conflicting values. The Humboldt Merger (HumMer) is a tool that allows ad-hoc, declarative fusion of such data using a simple extension to SQL. Guided by a query against multiple tables, HumMer...

Small jobs typically run for interactive data analyses in datacenters, and often are delayed by long-running tasks called stragglers. Many efforts, like Blacklist, speculative execution, proactive mitigation, have been devoted to the solutions. However, they either consume too much time or waste too many resources. In this paper, we propose a new proactive method to mitigate stragglers by perfo...
