Effect of femtosecond laser beam angle on bond strength of zirconia-resin cement
No full textKEPCEOGLU, Abdullah/0000-0002-4743-5517; DEMIRTAG, ZULFIKAR/0000-0002-7122-8876;Yttrium-stabilized tetragonal zirconia polycrystalline (Y-TZP) ceramic is widely used as an all-ceramic core material because of its enhanced mechanical and aesthetic properties. The bond strength of Y-TZP restorations affects long-term success; hence, surface treatment is required on ceramic boundaries. This study evaluated the effect of different laser beam angles on Y-TZP-resin cement shear bond strength (SBS). Forty plates of Y-TZP ceramics were randomly assigned to four groups (n = 10). A femtosecond amplifier laser pulse was applied on Y-TZP surface with different incidence angles (90A degrees, 75A degrees, 60A degrees, 45A degrees). The resin cement was adhered onto the zirconia surfaces. The SBS of each sample was measured using universal testing machine at crosshead speed of 1 mm/min. The SBS was analyzed through one-way analysis of variance (ANOVA)/Tukey tests. The results showed that the degree of laser beam angle affects the SBS of resin cement to Y-TZP. The laser beam was applied to a surface with a 45A degrees angle which resulted in significantly higher SBS (18.2 A +/- 1.43 MPa) than other groups (at 90A degrees angulation (10.79 A +/- 1.8 MPa), at 75A degrees (13.48 A +/- 1.2 MPa) and at 60A degrees (15.85 A +/- 0.81 MPa); p < 0.001). This study shows that decreasing of the angle between the ceramic surface and the laser beam increased the SBS between the resin cement and the ceramic material, as well as the orifice

Task-Guided and Semantic-Aware Ranking for Academic Author-Paper Correlation Inference
No full textWe study the problem of author-paper correlation inference in big scholarly data, which is to effectively infer potential correlated works for researchers using historical records. Unlike supervised learning algorithms that predict relevance score of author-paper pair via time and memory consuming feature engineering, network embedding methods automatically learn nodes' representations that can be further used to infer author-paper correlation. However, most current models suffer from two limitations: (1) they produce general purpose embeddings that are independent of the specific task; (2) they are usually based on network structure but out of content semantic awareness. To address these drawbacks, we propose a task-guided and semantic-aware ranking model. First, the historical interactions among all correlated author-paper pairs are formulated as a pairwise ranking loss. Next, the paper's semantic embedding encoded by gated recurrent neural network, together with the author's latent feature is used to score each author-paper pair in ranking loss. Finally, a heterogeneous relations integrative learning module is designed to further augment the model. The evaluation results of extensive experiments on the well known AMiner dataset demonstrate that the proposed model reaches significant better performance, comparing to a number of baselines.We would like to thank Yuxiao Dong for suggestions.

Kajian Sastra Perjalanan dalam Hikayat Kisah Pelayaran Abdullah ke Mekah Karya Abdullah Bin Abdul Kadir Munsyi
No full textThis research is aimed to identify and to reveal a hikayat as classic travel literature of Indonesia by the travel writing theory of Carl Thompson. To gain those purposes, this research used literary criticism and descriptive-analytic methods. The object of this study is Kisah Pelayaran Abdullah ke Mekah by Abdullah bin Abdul Kadir Munsyi (1854), focusing on the six elements of travel writing by Carl Thompson’s approach based on the hikayat. This study shows that the hikayat contains six elements of travel writing. Those are self, other, movement, space, encounter, and writing. Abdullah as a sailor puts himself in his hikayat as the main character by using “sahaya” and “aku” to articulate “self” in his hikayat. The “self” during travel met new and foreign things that the author had never seen before. He drew and expressed his point of view, feeling, and observation of all the encounters that he had met during sailing in to hikayat.Keywords: Carl Thompson, hikayat, travel writin
Dynamic augmentation of SCORM pre-authored course materials with adaptive links to supplementary resources
No full textIn a SCORM compliant courseware, content and the pedagogic approach to be taken are predefined by the course author. As a consequence, users are unable to learn according to their preferences, and implicitly they will all encounter the same learning experience. Recent attempts to personalise learning in SCORM often resulted in either modifying or substituting SCORM specification elements. Nonetheless, SCORM is a widely-used solution to interoperability problems. For this reason, this work focuses on supplementing SCORM rather than redefining it. This is accomplished by dynamically associating each pre-authored learning material in a SCORM package with adaptive links to relevant supplementary resources upon delivery. As a result, we have developed a Personalised Link Service (PLS) to deliver these links into user’s SCORM-compliant learning environment. In this paper, we present the design of a PLS authoring architecture which enables the automatic generation of a concept map from a SCORM package and consequently links to alternative learning resources, and a PLS run-time service oriented architecture which delivers these alternative resources, alongside the SCORM defined resources, according to a user model. We demonstrate the feasibility of our architecture by implementing a service to support a simple notion of a user model (Preferred Learning style)
Identifikasi Tokoh Abdullah bin Saba’ Dalam Literatur Sunni dan Syi’ah
No full textThis paper tries to explain the history of Abdullah bin Saba 'which was perpetuated by the scholars because of its enormous role in the dark history of the people in the early days of Islam, in this case it has been written by classical Ulama in the Chronicles Sunni, such as Imam at Tabari in inbook Tarikhhisscholars, clerics and others. so also in the books of Shiite scholars. However, there are those who doubt the path of the transmission because only from one lane, Abdullah bin Saba is 'doubtful and declares that Abdullah bin Saba' is a prominent figure. It starts from the path of transmission which is in the book of Chronicles, only one path. Therefore, the author tries to examine the path of transmission in the book of the Date. This study uses the content analysis method. As a source of data used in the study of the truth of Abdulllah bin Saba 'figure, namely through the perspective of the Sunni and Shia books. The author tries to explain the results of research that shows that the figure of Abdullah bin Saba 'the fact of his existence and information obtained from Sunni and Shia data sources has similarities about the figure
An investigation of localised surface plasmon resonance (LSPR) of Ag nanoparticles produced by pulsed laser deposition (PLD) technique
No full text32nd International Physics Congress of Turkish-Physical-Society (TPS) -- SEP 06-09, 2016 -- Bodrum, TURKEYNoble metal nano-structures such as Ag, Cu, Au are used commonly to increase power conversion efficiency of the solar cell by using their surface plasmons. The plasmonic metal nanoparticles of Ag among others that have strong LSPR in near-UV range. They increase photon absorbance via embedding in the active semiconductor of the solar cell. Thin films of Ag are grown in the desired particle size and interparticle distance easily and at low cost by PLD technique. Ag nanoparticle thin films were grown on micro slide glass at 25-36 mJ laser pulse energies under by PLD using nsNd:YAG laser. The result of this work have been presented by carrying out UV-VIS and AFM analysis. It was concluded that a laser energy increases, the density and size of Ag-NPs arriving on the substrate increases, and the interparticle distance was decreases. Therefore, LSPR wavelength shifts towards to longer wavelength region.Turkish Phys SocScientific and Technical Research Council of Turkey (TUBITAK)Turkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK) [1649B031503748]; Scientific Research Projects Coordination Unit of Selcuk UniversitySelcuk University [15201070, 15301020]This work was supported by the; Scientific and Technical Research Council of Turkey (TUBITAK) under Grant No. 1649B031503748 and Scientific Research Projects Coordination Unit of Selcuk University, Project No. 15201070 and 15301020.
