Article Citation - WoS: 13Citation - Scopus: 17A Mash-Up Application Utilizing Hybridized Filtering Techniques for Recommending Events at a Social Networking Site(Springer Wien, 2011) Kayaalp, Mehmet; Ozyer, Tansel; Ozyer, Sibel T.Event recommendation is one way of gathering people having same likes/dislikes. In today's world, many mass amounts of events are organized at different locations and times. Generally, cliques of people are fans of some specific events. They attend together based on each other's recommendation. Generally, there are many activities that people prefer/opt out attending and these events are announced for attracting relevant people. Rather than, peerto-peer oracles of a local group of people, or sentiments of people from different sources, an intelligent recommendation system can be used at a social networking site in order to recommend people in collaborative and content basis within a social networking site. We have used an existing social environment (http://www.facebook.com) for deployment. Our application has also been integrated with several web sites for collecting information for assessment. Our system has been designed in modules so that it is open to new data sources either by using web services or web scraping. Currently, our application is yet an application that permits users rate events; they have attended or have beliefs on them. Given the social network between people, system tries to recommend upcoming events to users. For this purpose, we have exploited the fact that a similarity relationship between different events can exist in terms of both content and collaborative filtering. Geographical locations have an impact so; we have also taken geographical location information and social concept of an event. Eventually, our system integrates different sources in facebook (http://www.facebook.com) for doing recommendation between people in close relationship. We have performed experiments among a group of students. Experiments led us have promising results.Article Citation - WoS: 1Citation - Scopus: 1On Stability in the Thermoelastostatics of Dipolar Bodies(Springer Wien, 2018) Ochsner, Andreas; Baleanu, Dumitru; Marin, MarinOur study is concerned with the initial boundary value problem in the context of the thermoelastostatics of dipolar bodies. We will derive a result which describes the exponential spatial decay of solutions of this problem. We will also find a superior limit for the amplitude, which is dependent on the initial and boundary conditions.Article Citation - WoS: 24Citation - Scopus: 26Stable Numerical Approach for Fractional Delay Differential Equations(Springer Wien, 2017) Pandey, Rajesh K.; Baleanu, D.; Singh, HarendraIn this paper, we present a new stable numerical approach based on the operational matrix of integration of Jacobi polynomials for solving fractional delay differential equations (FDDEs). The operational matrix approach converts the FDDE into a system of linear equations, and hence the numerical solution is obtained by solving the linear system. The error analysis of the proposed method is also established. Further, a comparative study of the approximate solutions is provided for the test examples of the FDDE by varying the values of the parameters in the Jacobi polynomials. As in special case, the Jacobi polynomials reduce to the well-known polynomials such as (1) Legendre polynomial, (2) Chebyshev polynomial of second kind, (3) Chebyshev polynomial of third and (4) Chebyshev polynomial of fourth kind respectively. Maximum absolute error and root mean square error are calculated for the illustrated examples and presented in form of tables for the comparison purpose. Numerical stability of the presented method with respect to all four kind of polynomials are discussed. Further, the obtained numerical results are compared with some known methods from the literature and it is observed that obtained results from the proposed method is better than these methods.Article Citation - WoS: 36Citation - Scopus: 45Relationships of Internet Addiction and Internet Gaming Disorder Symptom Severities With Probable Attention Deficit/Hyperactivity Disorder, Aggression and Negative Affect Among University Students(Springer Wien, 2019) Evren, Cuneyt; Evren, Bilge; Dalbudak, Ercan; Topcu, Merve; Kutlu, NilayThe aim of the present study was to evaluate relationships of Internet addiction (IA) and Internet gaming disorder (IGD) symptom severities with probable attention deficit/hyperactivity disorder (ADHD) and aggression among university students, while controlling the effects of anxiety and depressive symptoms. The study was conducted with online survey among 1509 volunteered university students in Ankara who regularly use the Internet, among whom we conducted analyses related with IA. Among these students, 987 of them, who play video games, were included in the analyses related with IGD. Correlation analyses revealed that the severities of the scale scores were mildly correlated with each other both among students who regularly use the Internet and students who play video games. Probable ADHD was associated with the severity of IA symptoms, together with depression and aggression, particularly physical aggression and hostility, in ANCOVA analyses. Similarly probable ADHD was also associated with the severity of IGD symptoms, together with depression and aggression, particularly physical aggression, anger and hostility, in ANCOVA analyses. These findings suggest that the presence of probable ADHD is related with both severity of IA and IGD symptoms, together with aggression and depression.Article Citation - WoS: 9Citation - Scopus: 10On Fractional Duffin-Kemmer Equation(Springer Wien, 2016) Merad, M.; Baleanu, D.; Bouzid, N.In this paper we treat a fractional bosonic, scalar and vectorial, time equation namely Duffin-Kemmer-Petiau Equation. The fractional variational principle was used, the fractional Euler-Lagrange equations were presented. The wave functions were determined and expressed in terms of Mittag-Leffler function.
