Personal skill information on social media is at the core of many interesting applications. In this paper, we propose a factor graph based approach to automatically infer skills from personal profile incorporated with both personal and skill connections. We first extract personal connections with similar academic and business background (e.g. co-major, co-university, and co-corporation). We the...

Accurate placing of securely tied knots in laparoscopic surgery is technically demanding and time consuming. Surgeons must face difficulties arising from 2-dimensional vision, spatial limitations, and restricted movement. Issues to be taken into account include security, virtuosity, and cost effectiveness. The authors believe that in spite of advances in instrumentation and optics, training sho...

Excellent book is always being the best friend for spending little time in your office, night time, bus, and everywhere. It will be a good way to just look, open, and read the book while in that time. As known, experience and skill don't always come with the much money to acquire them. Reading this book with the PDF hierarchical voronoi graphs spatial representation and reasoning for mobile rob...

This paper presents a marker free computer vision based system for tracking the articulated movement of hands in order to measure surgical skill. Tracking is achieved with a fast level set evolution method for active contours based on edge information. The spatial positions of anatomical features like the middle of the arm and of the wrist are computed from stereo images. Our first measurements...

Policy makers worldwide put great emphasize on national and regional ICT development not least because it is believed to constitute a decisive factor for enhancing competitiveness and sustaining growth. And indeed a row of empirical studies suggests that ICTs have a positive impact on economic development. At the same time, Internet infrastructure and technology adoption appear to reinforce exi...

Effective robot programming by demonstration requires the availability of multiple demonstrations to learn about all relevant aspects of the demonstrated skill or task. Typically, a human teacher must demonstrate several variants of the desired task to generate a sufficient amount of data to reliably learn it. Here a problem often arises that there is a large variability in the speed of executi...

Although citizen science projects such as eBird can compile large volumes of data over broad spatial and temporal extents, the quality of this data is a concern due to differences in the skills of volunteers at identifying bird species. Species accumulation curves, which plot the number of unique species observed over time, are an effective way to quantify the skill level of an eBird participan...

Article history: Received 27 July 2007 Received in revised form 21 February 2008 Accepted 2 May 2008 Available online xxxx An ensemble smoother is used to estimate the initial conditions and mortality rates for a spatially explicit model of Alexandrium fundyense. The data assimilation procedure is effective at reducing model-data misfit in this strong constraint problem formulation. The skill o...

Expert and intermediate chess players attempted to choose the best move in five chess positions while their eye movements were monitored. Experts were faster and more accurate than intermediates in choosing the best move. Experts made fewer fixations per trial and greater amplitude saccades than did intermediates, but there was no difference in fixation duration across skill groups. Examining t...

[1] We present results from continued investigations into the fidelity of covariance-based climate field reconstruction (CFR) approaches used in proxy-based climate reconstruction. Our experiments employ synthetic ‘‘pseudoproxy’’ data derived from simulations of forced climate changes over the past millennium. Using networks of these pseudoproxy data, we investigate the sensitivity of CFR perfo...
