Abstract

In the case of medical science, one of the most restless researches is the identification of abnormalities in brain. Electroencephalogram (EEG) is the main tool for determining the electrical activity of brain and it contains rich information associated to the varieties physiological states of brain. The purpose of this task is to identify the EEG signal as order or disorder. It is proposed to enrich an automated system for the identification of brain disorders. An EEG signal of a patient has been taken as a sample. The simulation has been done by MATLAB. The file which consists of the signal has been called in and plotted the signals in MATLAB. The proposed system covers pre-processing, feature extraction, feature selection and classification. By the pre-processing the noises are ejected. In this case the signal has been filtered using band pass filter. The Discrete Wavelet Transform (DWT) has been used to decompose the EEG signal into Sub-band signal. The feature extraction methods have been used to extract the EEG signal into frequency domain and the time domain features. The SNR (Signal to Noise ratio) is obtained in this work is 1.1281dB.

Abstract

This paper describes the design of an artificial neural network (ANN) control with power sharing control abilities of a new proposed double-input boost power converter (DIBC). The goal of this research is to model and design a high effectiveness and great performance double-input power converter for renewable energy applications. First, an artificial neural network controller design which is flexible versus a variable input voltage resource and variable load (to achieve the line regulation test and load regulation test) is proposed. Lastly, the suggested concept has been validated through experimentally on the laboratory prototype by using DSP TMS320F28335 real-time digital control. The experimental outcomes emphasize the authenticity of the suggested topology, which can be promising a novel topology that includes double-input power converter appropriate for renewable energy application systems.

Abstract

A self-configured network forming an arbitrary topology of mobile routers through wireless connection is commonly referred as MANET (mobile ad-hoc network).  Random movement of routers allows the network to organize arbitrarily hence rapid unpredictable changes may occur in the topology of the wireless network. When there is no possibility of setting up permanent networks, MANETs are set up for carrying out the operations temporarily. As there is no fixed frame for this system, usage of available resources for reliable communication is a great challenge for MANETs. The nodes participating in packet routing in ad-hoc networks faces security issues such as maintaining the confidentiality of the packets, integration, availability of the network to meet the traffic, requirement of authentication for reliable data communication etc. Dropping of packets maliciously in an attack is known as black hole attack.An attempt is made in this paper to detect dynamically using the security of cross layer called as honeypot and classify the mechanisms to understand the strengths & threats of the protocols used for routing to suggest a concrete solution for the problems related to the mobile ad-hoc networks. The methodology of honeypot detects and isolates the attacks of the black hole. The results prove better delivery of packets with decreased load of the network.

Abstract

Today, the internet is increasingly being considered to provide services, and not just in order to connect. As this view became more universal, the important factors of providing such services are reliability and availability of the services to meet the needs of a large number of users. Anycast is a communication mode in which the same address is assigned to a group of servers and the router will send the request to the ”best” server. Al-Ibrahim and Cerny proposed an authentication scheme of anycast communication. Their scheme is based on El-Gamal type signature scheme. We prove that their preferred scheme, which does not require interaction among the various signers, is insecure. DOI : http://dx.doi.org/10.11591/telkomnika.v12i4.4931

Abstract

Despite the advantages of the industrial wireless standards such as WirelessHART, ISA100.11a and Wireless Networks for Industrial Automation-Process Automation (WIA-PA), their application still faces a lot of challenges especially when it comes to interfacing with the real plant. This is due to lack of adequate infrastructures such as interfacing circuitry to establish communication between the WirelessHART nodes and the actuators and sensors. Therefore, this paper presents the application of locally developed WirelessHART adaptors for flow process control. The adaptors serve as an interface between the WirelessHART network and the sensor and actuator of the plant. Experimental results of the controllers compared showed that wireless control is possible through the use of the adaptors.

Abstract

Air ticket sales revenue is an important source of revenue for travel agencies, and if future air ticket sales revenue can be accurately forecast, travel agencies will be able to advance procurement to achieve a sufficient amount of cost-effective tickets. Therefore, this study applied the Artificial Neural Network (ANN) and Genetic Algorithms (GA) to establish a prediction model of travel agency air ticket sales revenue. By verifying the empirical data, this study proved that the established prediction model has accurate prediction power, and MAPE (mean absolute percentage error) is only 9.11%. The established model can provide business operators with reliable and efficient prediction data as a reference for operational decisions. DOI: http://dx.doi.org/10.11591/telkomnika.v11i11.2762

Abstract

Fibre Bragg Grating is an optical fibre that widely use as sensor to sense strain, temperature and pressure. The advantages of FBG sensor are it will not affected by electromagnetic interference which can improve the accuracy of the result and also can be wearable sensor. In this paper, Optisystem software tools are used to analyse the strain performance of FBG sensor for monitoring knee joint movement in rehabilitation process. Single mode FBG with original wavelength of 1550nm are used to get the accurate result because of less attenuation and absorption factor. This project also analysed the wavelength shifted when strain experienced by FBG change. The accuracy of sensor and method of delivering the result are taken into the account. The interrogator are used to display the wavelength shifted by the FBG when there is change in strain experienced by FBG. All of the proposed designed are tested by using simulation software and the wavelength shifted in the simulation are compared to the theoretical value that has been calculated in this project. The development of this system expected to improve the rehabilitation process towards a healthy life.

Abstract

High data rate communication in terrestrial wireless scenarios can be accomplished by setting up Base Stations (BS) on the ground. But applying the similar technique to maritime communication may not be suitable because owing to the geographically constrained nature of the ocean, henceforth, MF/HF modems, extensive-distance transmission characteristics with low data-rate are commonly employed in maritime communiqué. Inmarsat is conservatively used in Maritime satellite communiqué in order to reimburse for low data-rate transmission of MF/HF modems, but its main negative aspect is high cost. To improve the transmission speed along with low price, in general, a network whose architecture is similar to Vehicular Adhoc Network (VANET), that permits peer-to-peer transportation without BS, i.e., ad-hoc network is critical. An ad-hoc network for nautical environment named as Nautical Ad-hoc Network (NANET) was proposed. Multiple access and duplexing schemes are used to implement the nautical network for corresponding NANET scenarios.
