Recently, communication network services have become increasingly diverse and dynamic. Network Function Virtualization (NFV) is an effective technique to deal with these dynamic situations. Most related work on the VNF placement problem does not consider the dynamics of requests, but only static scenarios. The important goals of the dynamic VNF placement problem include accommodating new requests...
Software Defined Network (SDN) and Network Function Virtualization (NFV) are effective techniques to deal with dynamically changing network environments. Furthermore, the combination of SDN and NFV permits telecommunication service providers to offer sequences of virtualized network functions to their users through Service Function Chaining (SFC). In the context of SFC, the Virtual Network Function...
Functional magnetic resonance imaging (fMRI) is a technique to measure brain activity dynamics as the time series of spatial measurement units (voxels). Each voxel aggregates the neural activity in its spatial region, which changes over time depending on an external stimulus and the activities of other voxels. This paper uses fMRI data from a visual stimulus experiment to extract transition rules...
This paper presents a nonlinear model of the human brain activity response to visual stimuli according to Blood-Oxygen-Level-Dependent (BOLD) signals scanned by functional Magnetic Resonance Imaging (fMRI). A BOLD signal usually contains a low frequency signal component (trend), which is often ignored by the existing models or removed by approximation methods. However, such detrending could also destroy...
Recently, there are increasing efforts to define new protocols and architectures for data-centric networking that do not rely on the addresses of the individual network nodes. In that case, queries are usually disseminated by flooding throughout the network until the node with the requested content is found. However, flooding always imposes an additional burden on the network since many unnecessary...
