Detection of micro contamination in hard disk drives using angle measurements and Bayesian classification
(Journal of Computers;Vol. 29 No. 1, 2018, Journal article, 2018)Micro Contamination has been a major critical defects peculiar to the hard disk drive assembly particularly to head gimbal assembly compartment and it occurs mainly on the airbearing surface. Consequently, reliable measures ... -
Detection of micro contamination in hard disk drives using maximum likelihood estimation and angle detection
(Chapter; Peer reviewed; Chapter, 2016)Micro contamination is one of the critical defects that occur on the head gimbal assembly (HGA). The HGA is a key component of the read/write assembly of a hard disk drive. This paper presents an image-based automatic ... -
Determining the Geographical Location of Image Scenes based on Object Shadow Lengths
(Journal of Signal Processing Systems;65 (1), Journal article; Peer reviewed, 2011)Many studies have addressed various applications of geo-spatial image tagging such as image retrieval, image organisation and browsing. Geo-spatial image tagging can be done manually or automatically with GPS enabled ... -
Developing heuristics for evaluating the accessibility of digital library interfaces
(Lecture Notes in Artificial Intelligence;, Journal article; Peer reviewed, 2017)Digital libraries are important resources for the education of all, including people with disabilities.

Development of printed animated graphic images based on optical illusions
(CEUR Workshop Proceedings;Vol-2533, Digital Content & Smart Multimedia 2019. Proceedings of the 1st International Workshop on Digital Content & Smart Multimedia (DCSMart 2019), Conference object, 2019)The development of animated images that are printed on paper is covered in this article. Animated images are based on the illusion effect. Optical illusions include errors in visual perception caused by the inaccuracy or ... -
Déjà vu - Predicting the number of players in online games through normalization of historical data
(Chapter; Peer reviewed, 2011)A key factor to delivering a good online gaming experience is to have sufficient server resources relative to the number of players online. In this work, we present a simple profiling technique which allows effective ... -
Diagnosing Schizophrenia from Activity Records using Hidden Markov Model Parameters
(Annual IEEE Symposium on Computer-Based Medical Systems;2021 IEEE 34th International Symposium on Computer-Based Medical Systems, Conference object, 2021-07-12)The diagnosis of Schizophrenia is mainly based on qualitative characteristics. With the usage of portable devices which measure activity of humans, the diagnosis of Schizophrenia can be enriched through quantitative features. ... -
Different representations of the Levi-Civita Bertotti Robinson solution
(The European Physical Journal Plus;128, Journal article; Peer reviewed, 2013-04-23)The Levi-Civita Bertotti Robinson (LBR) spacetime is investigated in various coordinate systems. By means of a general formalism for constructing coordinates in conformally flat spacetimes, coordinate transformations ... -
