We present dRMT (disaggregated Reconfigurable Match-Action Table), a new architecture for programmable switches. overcomes two important restrictions of RMT, the predominant pipeline-based switches: (1) table memory is local to an RMT pipeline stage, implying that not used by one stage cannot be reclaimed another, and (2) hardwired always sequentially execute matches followed actions as packets traverse stages. show these make it difficult programs efficiently on RMT.

Traditional forest fire detection methods based on flame are subject to delays due the later appearrance of than smoke. When is detected, might have already been spread and out control. Therefore, objective this paper study new method First a quadrotor unmanned aerial vehicle (UAV) adopted capture video; then collected video sequence will be processed by series preprocessing including filtering image enhancement; finally significance algorithm investigated for early efficient smoke...

The consensus of the automotive industry and traffic management authorities is that autonomous vehicles must follow same laws as human drivers. Using formal or digital methods, natural language rules can be translated into machine used by vehicles. In this paper, a translation flow designed. Beyond translation, deeper examination required, because semantics languages are rich complex, frequently contain hidden assumptions. issue how to ensure accurate consistent with original intent they...

There is significant demand to rapidly obtain protein structure information for both structural genomics and drug discovery applications. To meet this demand, all steps in the process of determining by X-ray crystallography need be optimized streamlined with high-throughput methodologies. This communication describes a method that brings technology crystallization manual automated modes, suitable virtually every laboratory.

The seismic response of hydraulic tunnels is a complex nonlinear process.

Real-world surface textures normally comprise rough geometry and various reflectance properties. These are different from 2D still texture as their images can therefore vary dramatically with illumination directions. Research into hole filling has long been focusing on images, surfaces of 3D models or video clips to reconstruct missing information around the area. However, no reports available regarding for textures. This paper presents a simple framework holes texture. Firstly, we represent...
