A Robust Algorithm for Emoji Detection in Smartphone Screenshot Images

The increasing use of smartphones and social media apps for communication results in a massive number of screenshot images. These images enrich the written language through text and emojis. In this regard, several studies in the image analysis field have considered text. However, they ignored the use of emojis. In this study, a robust two-stage algorithm for detecting emojis in screenshot images is proposed. The first stage localizes the regions of candidate emojis by using the proposed RGB-channel analysis method followed by a connected component method with a set of proposed rules. In the second verification stage, each of the emojis and non-emojis are classified by using proposed features with a decision tree classifier. Experiments were conducted to evaluate each stage independently and assess the performance of the proposed algorithm completely by using a self-collected dataset. The results showed that the proposed RGB-channel analysis method achieved better performance than the Niblack and Sauvola methods. Moreover, the proposed feature extraction method with decision tree classifier achieved more satisfactory performance than the LBP feature extraction method with all Bayesian network, perceptron neural network, and decision table rules. Overall, the proposed algorithm exhibited high efficiency in detecting emojis in screenshot images

B!SON: A Tool for Open Access Journal Recommendation

Finding a suitable open access journal to publish scientific work is a complex task: Researchers have to navigate a constantly growing number of journals, institutional agreements with publishers, funders’ conditions and the risk of Predatory Publishers. To help with these challenges, we introduce a web-based journal recommendation system called B!SON. It is developed based on a systematic requirements analysis, built on open data, gives publisher-independent recommendations and works across domains. It suggests open access journals based on title, abstract and references provided by the user. The recommendation quality has been evaluated using a large test set of 10,000 articles. Development by two German scientific libraries ensures the longevity of the project

Tracking the Temporal-Evolution of Supernova Bubbles in Numerical Simulations

The study of low-dimensional, noisy manifolds embedded in a higher dimensional space has been extremely useful in many applications, from the chemical analysis of multi-phase flows to simulations of galactic mergers. Building a probabilistic model of the manifolds has helped in describing their essential properties and how they vary in space. However, when the manifold is evolving through time, a joint spatio-temporal modelling is needed, in order to fully comprehend its nature. We propose a first-order Markovian process that propagates the spatial probabilistic model of a manifold at fixed time, to its adjacent temporal stages. The proposed methodology is demonstrated using a particle simulation of an interacting dwarf galaxy to describe the evolution of a cavity generated by a Supernov

Investigation of mobile devices usage and mobile augmented reality applications among older people

Mobile devices such as tablets and smartphones have allow users to communicate, entertainment, access information and perform productivity. However, older people are having issues to utilise mobile devices that may affect their quality of life and wellbeing. There are some potentials of mobile Augmented Reality (AR) applications to increase older users mobile usage by enhancing their experience and learning. The study aims to investigate mobile devices potential barriers and influence factors in using mobile devices. It also seeks to understand older people issues in using AR applications

Smart Economy, Smart City, and Halal Tourism Industry: Global Islamic Economic Perspective in Indonesia

This article investigates smart city as a city that strives to make itself smarter, more efficient, sustainable, fair and livable.Thekeyelementsofsmartcity'sfoundation include urban planning and design, basic infrastructure and policies, as well as the integration of several smart technologies (ICT) that have emerged alongside core investments in developing various basic components of the city. The smart economy is related to economic competitivenessandinvolvesinnovation, entrepreneurship,economicimage,efficiencyand flexibility in the labor market, integration in local and international markets and the ability to change. The smarteconomyinasmartcityisimportantinthe development of halal tourism industry. This article mainly focuses on how the key factors of a smart economy and the basic elements of the smart city provide answers to the challenges and future development of halal tourism industry in Indonesia. By applying the approach to the main indicators of the global Islamic economy report 2018/2019toanalyzethelinkagesbetweensmart economy, smart city, and halal tourism industry, this paper confirms that smart economy concerns an open, transparent, diverse economy that adds value to smart cities.Thecharacteristicsincludeavarietyof employment opportunities with labor market flexibility, a diversificationthatpromotesentrepreneurshipand innovation and more productivity through local, regional andglobalinterconnectionsimplementedinthe development of the halal tourism industry in Indonesia

State, Society and Islam in the Western Regions of the Sahara

This open access book takes a deeper and broader perspective of the Hassaniya-speaking groups of the western region of the Sahara. There has been a surge of interest in this region, often centred around sensationalist news reports and policy briefs. But in-depth understanding and analysis remains neglected and little work has been undertaken on the diverse experiences of these groups and the contrasting political regimes under which they live. The contributors here focus on the complex and ambiguous relations between statehood, Islam, nation building and identity formation in hassanophone northwest Africa, ranging from southern Morocco, the Western Sahara and Mauritania to Algeria. The book uses up-to-date fieldwork to provide fresh analysis of and an insiders' perspective on these populations and their regional interactions, with contributions from the fields of law, Islamic studies, history, anthropology, politics, gender and media studies and the research of scholars from both the global North and global South. This interdisciplinary collection shows how urban ways of life are being adopted, with Hassaniya-speaking actors adjusting to state-administered social policies and new modes of settling disputes and legal claims. In doing so, the book sheds new light on the region's shifting social hierarchies, the new gendered power dynamics, and generational changes in the re-interpretation of 'tradition'. As well as displaying that the Hassaniya-speaking groups are pivotal to the development of the region’s political culture, the book also reveals their close association with Islam, both as a religious expression as well as a cultural marker. A much-needed contribution on the intersections of politics, Islam and identity in northwest Africa
