With the advancement of user application service demands, IoT system tends to offload tasks edge server for execution. Most current studies on computation offloading ignore dependencies between components application. The few pieces research computing which focus topology are primarily applied in single-user scenarios. Unlike previous work, our work mainly solves dependent task with multiuser scenarios, is more line reality. In this article, problem modeled as a Markov decision process (MDP)...

Hand, foot and mouth disease (HFMD) is a common pediatric illness mainly caused by infection with enterovirus 71 (EV71) coxsackievirus A16 (CA16). The frequent HFMD outbreaks have become serious public health problem. Currently, no vaccine or antiviral drug for EV71/CA16 infections has been approved. In this study, two-step screening platform consisting of reporter virus-based assays cell viability‑based was developed to identify potential inhibitors infection. Two types viruses, pseudovirus...

We propose a generalized approach to decoupling shading from visibility sampling in graphics pipelines, which we call decoupled . Decoupled enables stochastic supersampling of motion and defocus blur at reduced cost, as well controllable or adaptive rates trade off quality for performance. It can be thought generalization multisample antialiasing (MSAA) support complex dynamic mappings samples, introduced by shading. works defining many-to-one hash using buffer memoize samples exploit reuse...

Light scattering in a participating medium is responsible for several important effects we see the natural world. In presence of occluders, computing single requires integrating illumination scattered towards eye along camera ray, modulated by visibility light at each point. Unfortunately, incorporating volumetric shadows into this integral, while maintaining real-time performance, remains challenging.

Volumetric effects such as beams of light through participating media are an important component in the appearance natural world. Many can be faithfully modeled by a single scattering medium. In presence shadows, rendering these prohibitively expensive: current algorithms based on ray marching, i.e., integrating illumination scattered towards camera along each view ray, modulated visibility to source at sample. Visibility must determined for sample using shadow rays or shadow-map lookups. We...

Texture variation on real-world objects often correlates with underlying geometric characteristics and creates a visually rich appearance. We present technique to transfer such geometry-dependent texture from an example textured model new geometry in consistent way. It captures the correlation between set of features, as curvature, observed diffuse texture. perform dimensionality reduction overcomplete feature which yields compact guidance field that is used drive spatially varying synthesis...

With the proliferation of mobile device users, Device-to-Device (D2D) communication has ascended to spotlight in social network for users share and exchange enormous data. Different from classic online (OSN) like Twitter Facebook, each single data file be shared D2D is often very large size, e.g., video, image or document. Sometimes, a small number interesting files may dominate traffic, lead heavy congestion. To reduce traffic congestion design effective caching strategy, it highly...
