These articles have been peer-reviewed and accepted for publication in IJHT, but are pending final changes, are not yet published and may not appear here in their final order of publication until they are assigned to issues. Therefore, the content conforms to our standards but the presentation (e.g. typesetting and proof-reading) is not necessarily up to the Inderscience standard. Additionally, titles, authors, abstracts and keywords may change before publication. Articles will not be published until the final proofs are validated by their authors.

  • Cancer tissue sample classification using point symmetry based clustering algorithm   Order a copy of this article
    by Sudipta Acharya, Sriparna Saha 
    Abstract: Clustering or unsupervised classification techniques can be used to\r\nsolve different types of classification problems of different domains. Symmetry\r\nis an important property for any real life object. Therefore symmetry based\r\ndistance measurements play some important roles in identifying some patterns\r\nor clusters of real life data sets. In this paper inspired by the symmetric property\r\nwe have proposed a point symmetry based clustering algorithm which has been\r\nused to identify clusters of tissue samples from some real life cancer data\r\nsets. Our proposed algorithm is also multi-objective-optimization(MOO) based,\r\ni.e., optimizes more than one objectives simultaneously. We have also shown\r\nthe superiority of our proposed algorithm with respect to some state-of-the-art\r\nclustering algorithms.\r\n

  • Augmenting WAMPAC with Machine Learning Tools for Early Warning and Mitigation of Blackout Events   Order a copy of this article
    by Sudha Gupta, Faruk Kazi 
    Abstract: The development of phasor measurement unit (PMU) in the power network and availability of real time communication in wide area monitoring system has enabled the proactive blackout prediction and possibility of mitigation against blackout events. The objective of this paper is to provide a wide area monitoring protection and control (WAMPAC) model which can predict cascade failure and minimize the risk of massive blackout. The proposed model is a combination of simulation and a measurement based approach. The key contribution of this paper is a topological analysis of grid using graph theoretic approach, blackout prediction using machine learning tool and the mitigation plan against blackout by combining graph theoretic approach and change in voltage phase angle at different buses. The proposed methodology is validated using IEEE 30 bus system.
    Keywords: Blackout Prediction; Cascade Failure; Grid Topology; Neural Network (NN); Phasor Measurement Unit (PMU); Phasor Data Concentrator (PDC); Probability distribution; Wide Area Monitoring Protection and Control (WAMPAC).

  • Evaluating the Feasibility of Maintaining Web 2.0 Communications During Civil Emergencies   Order a copy of this article
    by James Meneghello, Kevin Lee, Nik Thompson 
    Abstract: Maintaining communications across disconnected networks can be a troubling issue, particularly since existing solutions are highly theoretical or have unrealistic hardware requirements. As a result, CANDICE was designed with the aim of allowing extensible accessible facilitation of Internet connections in environments not suited to reliable communications - particularly hostile zones. Unfortunately, current web development trends (including a heavier emphasis on user interaction and asynchronous data transfer) ensure that less useful content is accessible without an uninterrupted Internet connection. By evaluating the operation of CANDICE in retrieving popular websites, types of content that are well-suited to transmission over disrupted networks can be determined.

  • Usable Technology for the Differently Abled - Hearing Impairment   Order a copy of this article
    by Chitralekha Bhat, Sunil Kumar Kopparapu 
    Abstract: The ability to see, hear and speak form the three corners of a communication triangle. A disability of any one of these hampers communication significantly. In this paper, we address how these disabilities can be overcome using technology. Specifically, we look at one of the problems, namely, how can we communicate the audio track in a video for the hearing impaired. Hearing loss is an invisible disability, hampering communication and poses a serious challenge to access information that are in the form of audio or video on the internet. Text subtitles or closed captioning is the most popular way to make the audio embedded in the videos accessible to the hearing impaired. The other popular method to make audio accessible is to have a sign language interpreter translate the audio into sign language gestures. However, these aids are either expensive or technologically infeasible making videos not accessible to the hearing impaired. In this paper, we propose the use of multiple techniques to enable a person with hearing impairment see the audio. The novel assistive tool is envisioned as a visual aid for the hearing impaired to comprehend the audio contained in a video. The tool essentially produces a speech synchronized visual lip movement sequences for a video. The lip movement sequence is then superimposed onto and displayed along with the original video. A number of experiments have been conducted to determine the feasibility and usefulness of the proposed visual aid.

  • Design of Near Optimal User Interface with minimal UI elements using Evidence based recommendations and Multi Criteria Decision Making: TOPSIS method   Order a copy of this article
    by Subbiah Vairamuthu, Margret Anouncia 
    Abstract: One among the research challenges in Human computer Interaction (HCI) is to build user interfaces in the way that make users satisfy. This improved satisfaction would reflect in cultivating the usability of any information systems. In any information systems, usability is one of the non-functional requirements because of which the acceptability of system gets determined by. Forgetting the usability factors during interaction design would cost more to any organizations. Improved interaction with simple interaction styles together with reduced navigations and user interface components may help the above stated factors during interface design in interface design. This work attempted to help designers involved in building user interfaces to recommend them with minimal number of user interface elements so as to facilitate interaction in an effective and easier ways. TOPSIS, a MCDM (Multi Criteria Decision Making) method for recommendations has been used in this approach.
