With the popularity of smart mobile devices, users can rely on global positioning system (GPS) technology when they are outdoors to determine their geographic location and use other navigation services. However, GPS cannot reliably obtain satellite signals indoors, is not suitable for indoor applications. Wi-Fi Bluetooth mainstream technologies used today. But these radio sometimes encounter problems, such as human-shadowing effects, multiple-path delays, radio-wave interference, which cause...

In this paper, we develop a novel fuzzy support vector machine for device-free localization. The is an integration of machines (SVMs) and systems; therefore system can be extracted from SVM. We not only show how to integrate SVMs systems, but also reduce the complexity obtained systems. One major benefit reducing systems that are easy optimized. proposed method proved effective through experimental studies, which carried in badminton court four WiFi access points 17 test deployed. simulation...

The purpose of this paper is to develop an agent that can imitate the behavior humans driving a car. When human beings car, he/she majorly uses vision system recognize states including position, velocity, and surrounding environments. In paper, we implemented self-driving car which drive itself on track simulator. deep neural network as computational framework "learn" what position related road. While understands track, it use information basis for feedback control.

Providing a customer with tailored location-based services (LBSs) is fundamental problem. For location-estimation techniques radio-based measurements, LBS applications are widely available for mobile devices (MDs), such as smartphones, enabling users to run multi-task applications. information not only enables obtaining the current location of an MD but also pro- vides real-time push-pull communication service. indoor environments, localization technologies based on radio frequency (RF)...

<para xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> This paper proposes a novel frequency-calibration approach based on an adaptive neural–fuzzy inference system (ANFIS). In normal mode, oven-controlled crystal oscillator (OCXO) is steered by integrating time-interval counter, fuzzy controller, digital-to-analog (D/A) converter, and other components such that its frequency can follow primary cesium atomic clock. addition, under the effects of...

This paper presents a novel combination of the dynamic Bayesian networks (DBNs) and constraint-based fuzzy models for myocardial infarction classification with 12-lead ECGs. Data lead-V1, V2, V3, V4 were selected. Then, DBNs used finding likelihood value which was treated as statistical feature data each heartbeat's ECG complex, to extract knowledge from trained DBNs. The model developed this approach is tested on 905 samples heartbeats clinical data, including 470 435 healthy individuals....

In this study, a fail-stop group signature scheme (FSGSS) that combines the features of and signatures to enhance security level original is proposed. Assuming FSGSS encounters an attack by hacker armed with supercomputer, can prove digital forged. Based on aforementioned objectives, study proposes three lemmas proves they are indeed feasible. First, how does recipient digitally signed document verify authenticity signature? Second, when under dispute, group’s manager determine identity...

A new scheme of frequency calibration based on adaptive neural-fuzzy inference system (ANFIS) is proposed in this paper. In normal mode, an oven-controlled crystal oscillator (OCXO) steered by integrating time interval counter (TIC), fuzzy controller, D/A converter, etc., such that its can follow a primary cesium atomic clock. addition, the ANFIS applied when enters holdover mode. Experimental results show stability OCXO be improved from few parts 10 <sup...

Android consists of a kernel based on the Linux kernel, with middleware, libraries and APIs written in C application software running an framework which includes Java-compatible libraries. The precision time synchronization protocol daemon (PTPd) is open source development that realizes PTP. In this work, we were porting PTPd android system measure performance network between two mobile devices. Moreover, demonstrate feasibility building by means NDK.

Most eye-tracking experiments are limited to single subjects because gaze points difficult track when multiple users involved and environmental factors might cause interference. To overcome this problem, paper proposes a method for tracking that can be applied simultaneously. Four models, including FASEM, FAEM FAFRCM in the signal-user environment, as well FAMAM multiple-user proposed, we collected raw data of gazing behaviors train models. Through modified VGG19 architecture adjusting...

This paper proposes an automated system to detect text regions and correct the orientation of textlines in natural images on mobile devices. Text are first detected using image operator called Stroke Width Transform. Textlines (text blocks) then extracted from based a modified minimum spanning tree algorithm. Finally, orientations corrected according way users hold device. The provides with interactive interface select blocks which catch their attention. Moreover, allows selected if results...

In this paper, we adopt a tapped delay line (TDL) equalizer as the arbiter of ensemble learning for device-free localization over IEEE 802.11 wireless local area network (WLAN). The proposed model is two-stage decision process. While an input signal along with given, trained support vector machine (SVM) and Bayesian classifier performs first stage prediction. Then, second selects most frequent one among intermediate outputs final output. Experimental results show method can not only to be...

The UMTS specification adopts the PQ/WFQ (priority queue/weight fair queue) scheduling where PQ is used to provide a low-latency dedicated service for conversational and steaming traffic WFQ relative delay interactive background classes. In this article we propose HPS (hierarchical packet scheduling) mechanism enhance performance of on network. proposed scheduler found that using performs better than from simulation results.
