In this paper, techniques and algorithms developed in the framework of statistical learning theory are analyzed and applied to the problem of determining the location of a wireless device by measuring the signal strengths from a set of access points (location fingerprinting). Statistical Learning Theory provides a rich theoretical basis for the development of models starting from a set of examp...

As architects, entrepreneurs, hoteliers, healthcare professionals and others embrace the Internet of Things (IoT) and the Smart Environment paradigms, developers will bear the brunt of constructing the IT relationships within these, making sense of the big data produced as a result, and managing the relationships between people and technologies. We explore how PolySocial Reality (PoSR), a frame...

In fields such as medicine, geography, and mechanics, spatial reasoning involves reasoning about entities that may coincide without overlapping. Some examples are: cavities and invading particles, passageways and valves, geographic regions and tropical storms. The purpose of this paper is to develop a formal theory of spatial relations for domains that include coincident entities. The core of t...

In this paper we consider, in a general normed space, the optimization problem with the objective function being a composite of a convex and componentwise increasing function with a vector convex function. Perturbing the primal problem, we obtain, by means of the Fenchel-Rockafellar approach, a dual problem for it. The existence of strong duality is proved and the optimality conditions are deri...

Linking accounts of the same user across datasets – even when personally identifying information is removed or unavailable – is an important open problem studied in many contexts. Beyond many practical applications, (such as cross domain analysis, recommendation, and link prediction), understanding this problem more generally informs us on the privacy implications of data disclosure. Previous w...

future increase of mobile communication subscribers will require a great capacity expansion of the cellular systems. in order to accommodate the increasing number of subscribers, the cell size will have to be much smaller than current size. therefore, it is predictable that the location updating and paging procedures will produce a major part of signaling traffic in these networks. this pape...

this paper presents a fault location technique for transmission lines with minimum current measurement. this algorithm investigates proper current ratios for fault location problem based on thevenin theory in faulty power networks and calculation of short circuit currents in each branch. these current ratios are extracted regarding lowest sensitivity on thevenin impedance variations of the netw...

This paper describes an application of statistical search theory to the important problem of location management in wireless networks. Statistical search theory is concerned with the optimal allocation of search eeort to identify the location of an object hidden in a subset of a given domain. In wireless networks , to establish a connection or route a packet to a mobile terminal, the exact loca...
