Abstract

This paper deals with the methods of verification of web-forum members’ personal data, which are implemented in the algorithm of registration and validation of personal data on web-community member. The problem of personal data verifying and method of registration in an online community is investigated. These issues have the greatest influence on efficiency rise of virtual communities functioning and the level of data authenticity in web-members’ personal profiles. Solution of these problems is possible by using computer-linguistic analysis of web-members’ posts.DOI: http://dx.doi.org/10.11591/ij-ict.v2i2.3960

Abstract

In wireless communication systems (WCS), channel characteristics are random and unpredictable. The resultant effect of the randomness is the multipath effect that leads to multipath fading. Multipath fading is a major contributor to the unreliability of wireless communication links. In this paper, Multiple-Input, Multiple-Output (MIMO) schemes were investigated in mitigating the effect of signal fading. Space-time coded MIMO-OFDM was developed to enhance the performance of the WCS. The performance of the developed space-time coded MIMO-OFDM over both flat and frequency selective channels were compared with that of conventional WCS. The simulation results show that the space-time coded MIMO-OFDM considerably reduced the effect of multipath fading in WCS with improved bit error rate (BER) value.DOI: http://dx.doi.org/10.11591/ij-ict.v2i2.2014

Abstract

Zhu et al. recently have proposed an authentication prpotocol forRFID systems. In this paper, we analyze its security and explain itssecurity drawbacks. More precisely, we present traceability attackagainst this protocol. In addition, we propose an improvement on theZhu et al.'s to resists these security drawbacks. Finally, weinvestigate the formal security of the improved protocol based on theBAN logic method.DOI: http://dx.doi.org/10.11591/ij-ict.v2i2.2077

Abstract

This study examines consumer’s perception related to perceived risk while doing transaction in e-auction system. Previous researches found there are some features in e-auction system recognized unclarity features as they indicate having fraud or cheating. In the online auction environment, perception could be categorized in two types such as privacy and security. This study proposed a conceptual framework based on perceived risks from consumer’s investigation, associated directly with four cost features of e-auction system: payment method, auction fee, bidding fee and third party services that combined with four perceived risk components: performance risk, psychological risk, financial risk, and time risk. Researcher has developed a questionnaire for collecting data from consumer’s who has experience in using e-auction. Through statistical analysis using multiple regressions, this study found that payment method, auction fee, and bidding fee have a positive impact on perceived risk. However, third party services have a significant effect upon consumer perceived risk on financial risk but not significant effect to time risk. Furthermore, the online auction features is directly related to reducing consumers' risk perception. As a summary, online auction features associated with financial play a crucial role in reducing consumers' perceived risk in online auction transactions.DOI: http://dx.doi.org/10.11591/ij-ict.v2i2.2529

Abstract

Hypoxia inducible factor (HIF) is the main protein in hypoxia pathway. The response of HIF to changes of oxygen pressure is regulated by 2 oxygen sensors, prolyl hydroxylase (PHD) and factor inhibiting HIF (FIH). Studies have shown that biochemical reactions at molecular level actually exhibit stochastic and random behaviors. Modeling biochemical reactions using purely deterministic method, therefore, ignore these characteristics. Hence, we use stochastic modeling using CTMC to model this regulation. Nevertheless, the use of pure CTMC on complex biochemical reaction networks, such as hypoxia, results in an infeasible computation time and typically requires very large memory. Therefore, we use a numerical hybrid method that combines pure CTMC and deterministic methods. The purpose is to reduce time complexity and to obtain a better accuracy than deterministic method. Using this model, we can observe that an increase of oxygen pressure results in a decrease in the amount of HIF and that oxygen sensor FIH only inhibits C-TAD activity. The model is also able to classify 84% genes that were observedDOI: http://dx.doi.org/10.11591/ij-ict.v2i2.3845

Abstract

In a VANET, the network topology is constantly changing. In fact, it requires distributed self-organizing security systems. In this article, we propose a distributed self-organizing trust management system for vehicular ad-hoc networks (VANETs), given the disastrous consequences of acting on false information sent by the malicious peers in this context. Our application can verify the correctness of alert messages sent by other vehicles about road accident. We opted to apply ambient communication technology to provide a self-organized network. We introduce the concept of “ambient intelligent vehicle” that consists in integrating ambient intelligence features in VANET. Vehicles are considered as intelligent agents that communicate in an ambient environment. Such vehicles are able to control and to detect false warning based on trust management system depicted in this article. Vehicles are arranged into clusters in order to facilitate communication and to reduce overhead. We model how vehicle operate using UML state diagram.DOI: http://dx.doi.org/10.11591/ij-ict.v2i2.2980

Abstract

The research of human-computer interfaces has become a growing field in computer science, which aims to attain the development of more natural, intuitive, unobtrusive and efficient interfaces. The present work describes a Human Machine Interface Based on Eye Wink Detection for helping the severely handicapped people to manipulate the household devices and to perform day to day activities. Algorithm for eye detection that is conductedthrough a process of extracting the face image from the video image followed by evaluating the eye region and then eventually detecting the eye state based on skin colour segmentation. Binary values 1 and 0 is assigned based on the opening and closing of eye. Finally applying the dynamic programming to translate the code sequences to a certain valid command. Experiment conducted for different test video displayed significant results which is carried out with different set of inputs.DOI: http://dx.doi.org/10.11591/ij-ict.v2i2.3927

Abstract

As a project is a lifeline of any organization, the critical success factors (CSFs) affect the success of the project in project management. This paper provides the literatures and reports as the concept paper which have been made by various researchers regarding the project success factors and change management. The critical success factors which have been applied and brought success to the different organizations will be elaborated in order to identify the factors are applied in Malaysian Institutions of Higher Learning (IHL). Furthermore, the value-driven relationship which consider three project elements, the Business,  Project Management Office and Project Team have to be well understood. Lastly,  the proposed framework of how the 3 elements mentioned above can lead to the successful in project development implementation which create competitive advantage, will be discussed as for the next step to conduct the empirical study.DOI: http://dx.doi.org/10.11591/ij-ict.v2i2.3351
