Sensor networks are typically purpose-built, designed to support a single running application. As the demand for applications that can harness the capabilities of a sensor-rich environment increases, and the availability of sensing infrastructure put in place to monitor various quantities soars, there are clear benefits in a model where infrastructure can be shared amongst multiple applications...

We suggest the reexamination of the validity of the Lorentz invariance at the small distance of the order of 10-16 cm in the light of high energy available at CERN and NAL. Using the modified weak interaction Lagrangian with a noncausal form factor we evaluate the muon decay lifetime including the effect of the radiative corrections as a function of the particle energy and characteristic length...

Video abstraction allows searching, browsing and evaluating videos only by accessing the useful contents. Most of the studies are using pixel domain, which requires the decoding process and needs more time and process consuming than compressed domain video abstraction. In this paper, we present a new video abstraction method in H.264/AVC compressed domain, AVAIF. The method is based on the norm...

Networked control systems (NCS), such as the smart power grid, implement feedback control loops by connecting distributed sensors and actuators to a remote controller over a communication network. In order to avoid the costly and timeconsuming installation of dedicated networks, NCS can bene t from utilizing readily available IP networks such as the Internet. However, as control systems are typ...

A novel abstraction of the available bandwidth in a communication network is presented based on the blocking island abstraction (Frei & Faltings 1997). Path computing algorithms using this abstraction are presented for non-hierarchical and hierarchical networks. For the latter case, a composeable abstraction of subnetworks is proposed.

A significant challenge in evaluating network security stems from the scale of modern enterprise networks and the vast number of vulnerabilities regularly found in software applications. A common technique to deal with this complexity is attack graphs, where a tool automatically computes all possible ways a system can be broken into by analyzing the configuration of each host, the network, and ...

We draw attention to network abstraction as a fundamental problem within network analysis and visualization. A combinatorial network abstraction problem is specified by a class P of pattern graphs and a real-valued similarity measure % based on certain graph properties. For fixed P and %, the optimization task on any graph G is finding a subgraph G′ which belongs to P such that %(G,G′) is minim...
