(2016-07-01)
In this study, we explore social media use by politicians by investigating affordances, effects and associated constraints of introducing social media within eParticipation. Based on an interpretive case study in the ...
Reexamining Usability Dimensions: The Case of Social Media
(IEEE, 2015-05)
This study aims to reexamine some traditional usability principles in the context of social media. The instrument was based on 14 items of usability dimensions (i.e. learnability, flexibility, and robustness) proposed by ...
Texture Feature Extraction using Improved Completed Robust Local Binary Pattern for Batik Image Retrieval
(Advanced Institute of Convergence Information Technology Research Center, 2016-11-10)
One of the robust texture feature extraction methods is Local Binary Pattern (LBP). LBP is a simple but efficient method and gray-scale invariant. Some studies have been proposed to improve the performance of LBP, such as ...

Ni dispersed on sulfated zirconia pillared montmorillonite as bifunctional catalyst in eco-friendly citronellal conversion
(Chulalongkorn University, 2015)
Preparation of nickel dispersed on sulfated zirconia pillared montmorillonite(Ni/S-Zr/MMT) and its application as catalyst in citronellal conversion was investigated. Preparation of material was conducted by three main ...
Effect of calcination temperature on the synthesis of ZrO2-pillared saponite to catalytic activity in menthol esterification
(Department of Chemistry, Gadjah Mada University, 2016-06)
The influence of calcination temperature on the synthesis of zirconia-pillared saponite (PILS) and on its catalytic activity in menthol esterification has been studied. Zirconia pillarization was conducted using zirconium ...
Microwave assisted preparation of TiO2/Al-pillared saponite for photocatalytic phenol photo-oxidation in aqueous solution
(Elsevier, 2015-03)
In present work, titania dispersed in aluminium pillared saponite was prepared by using microwave irradiation technique as a more efficient calcination procedure instead of conventional calcination by slow heating. Several ...
Physicochemical and photocatalytic properties of Fe-pillared bentonite at various fe content
(Diponegoro University, 2016-11-15)
Iron-pillared bentonites (Fe/Bents) were successfully prepared using a ferric chloride precursor. The prepared samples were characterized using XRD, BET and SEM-EDX. The results show that the pillared bentonite physicochemical ...
