the purpose of this paper is to obtain necessary and suffcient conditionsfor existence approximate fixed point on geraghty-contraction. in this paper,denitions of approximate -pair fixed point for two maps tα , sα and theirdiameters are given in a metric space.

We develop a method similar to variable elimination for computing approximate marginals in graphical models. An underlying notion in this method is that it is not always necessary to compute marginals over all the variables in the graph, but focus on a few variables of interest. The Focused Inference (FI) algorithm introduced reduces the original distribution to a simpler one over the variables...

This thesis compares approaches to the problem of discovering a mobile user's location indoors. The particular challenges of location discovery using 802.11 (Wi-Fi) signals and "organically collected" (i.e. user-generated) received signal strength maps are discussed. Several existing and novel localizer algorithms are compared on a database of organically collected data. Features of local Wi-Fi...

Indoor positioning based on existing Wi-Fi fingerprints is becoming more and more common. Unfortunately, the Wi-Fi fingerprint is susceptible to multiple path interferences, signal attenuation, and environmental changes, which leads to low accuracy. Meanwhile, with the recent advances in charge-coupled device (CCD) technologies and the processing speed of smartphones, indoor positioning using t...

Abstract: In recent decades, the proliferation of smart phones, tablets, and wireless networks has fostered a growing interest in indoor passive positioning. The Wi-Fi-based passive positioning systems can provide Location-Based Services (LBSs) to the third party such as market and security departments. Most of the existing systems are based on the Receive Signal Strength Indication (RSSI) info...

Dynamic Adaptive Streaming over HTTP (DASH) constitutes a large fraction of traffic in the mobile Internet. Mobile devices often use video delivery over Wi-Fi, which is a significant energy drain. Dynamic Power Saving Mode (DPSM) is one of the most widely-used approaches for Wi-Fi devices to save power and shorten packet delay. However, DPSM uses a fixed timeout before a device goes to sleep, l...

Background: In recent years, nanomaterials have been widely used in large quantities which make people bemore frequently exposed to the chemically synthesized nanoparticles (NPs). When NPs are introduced intoan organism, they may interact with a variety of cellular components with yet largely unknown pathologicalconsequences.Objective: I...

With service design open to third-party in the evolving telecom networks, dynamic method is suitable for feature interaction (FI) detection. When implementing this method, however, the violation of user intension is difficult to express as an indication of FI. To overcome this, a duplicate of Application Server called FRS (FeatureRepresentation Server) is proposed to add into the network, where...
