Signed networks with positive and negative links attract considerable interest in their studying since they contain more information than unsigned networks. Community detection and sign (or attitude) prediction are still primary challenges, as the fundamental problems of signed network analysis. For this, a generative Bayesian approach is presented wherein 1) a signed stochastic blockmodel is proposed...
A simulation model for analyzing electromagnetic on-body wave propagations is proposed. The simulation method utilizes motion capture input data, a simplified human phantom model, and full wave electromagnetic simulation methods. A comparison of simulation results and experimental data for differently-sized human body models is shown.
As an important computer graphics technique, parameter-driven animation has seen increasing deployment on mobile platforms, where both communication bandwidth and device storage are subjected to stringent constraints. We propose an efficient rate-distortion optimized inter-frame compression scheme for parameter-driven animation capable of finding optimal bit-allocations for any given bit-rate. Experiments...
A simulation platform for modelling and analyzing dynamic on-body electromagnetic wave propagations is proposed. This simulation method combines motion capture techniques, simplified human phantom model construction, and full-wave electromagnetic simulations. Two case studies are presented and verified with measurement results.
On-body wave propagation is investigated for low medical frequencies such as 433 MHz and 915 MHz. The paper applies the ground wave and creeping wave theories to calculate the approximate path gain, both along and around a human body. The formulas contain the characteristics of the human phantom shape and tissue properties. The analytical model is validated by FEKO simulation and measurements on a...

In the Smart Grid, Demand Response (DR) programs have been developed rapidly, which change the fixed mindsets of satisfying the growing power demand merely by the development of power supply side, and utilize the demand side resources as alternative energy sources. Nevertheless, in application of DR programs, there are many uncertain factors which cannot be reflected in conventional optimization approaches...
In order to reduce the unnecessary material and the time consumed, and to improve design efficiency in the actual prosthetics physical prototype design process, this paper uses virtual technology to build a simulation system. First, Adams software is used to create a virtual humanoid robot model with 14 degrees of freedom; second, a virtual bionic hand's fuzzy PID control system is built based on...
Agent-based modeling is a paradigm that simulates the simultaneous operations and interactions of multiple agents, in an attempt to re-create and predict the appearance of complex phenomena. Its key advantages are that a) it provides the most natural way to model real-world systems and b) it has much more modeling power than traditional mathematical methods such as differential equations as the latter...
Air Force Research Laboratory published the non-lethal Millimeter wave weapon “Active Denial System” (ADS). Because of the thermal shallow penetration induced by its high frequency, the penetration depth is always less than 1mm. Heat gathers at the skin surface, caused the strong thermal effect on the skin. We built up a transient thermal multilayer model for heating of human skin by high power millimeter...

In recent years, models are increasingly used throughout the entire lifecycle in software development projects. In effect, the need for collaborating on these models emerged, requiring change tracking and versioning. However, many researchers have shown that existing methods and tools for Version Control (VC) do not work well on graph-like models, such as UML, SysML or domain-specific modeling languages...
In the reliability prediction of the product with long life and high reliability, the step stress accelerated degradation test (SSADT) is commonly applied. With the motivation of predicting the product reliability most precisely, the problem of optimizing the test plans has drawn a lot of attentions in the application of SSADT. In this paper, the drift Brownian motion is selected as the degradation...
