Rumours are a kind of information that has a impact on social life and economies, which spread quickly and widely, especially, via internet. Recently, the spread of information affects our daily lives due to the increasing number of social media users. Rumours are defined in social areas which are delivered by gossips, fake news, marketing, social media all the way even to revolutions. In this paper, we study the dynamics of a rumour propagation model with a numerical approach. By using an algorithmic technique with an error analysis, the validity of the numerical technique is described. We investigate the model with this numerical approach to explain the dynamics of rumour propagation. Besides, we explain sensitivity analyses of the model of parameters. Then by numerical simulations efficiency of the technique is shown. Finally, the results are displayed and discussed with the help of figures and tables. The paper ends with a conclusion and an outlook to future studies.

Cooperative games under interval uncertainty: on the convexity of the interval undominated cores Branzei, R.; ALPARSLAN GÖK, Sırma Zeynep; Branzei, O. (Springer Science and Business Media LLC, 2011-12-01) Uncertainty is a daily presence in the real world. It affects our decision making and may have influence on cooperation. Often uncertainty is so severe that we can only predict some upper and lower bounds for the outcome of our actions, i.e., payoffs lie in some intervals. A suitable game theoretic model to support decision making in collaborative situations with interval data is that of cooperative interval games. Solution concepts that associate with each cooperative interval game sets of interval allocat...
An application of the minimal spanning tree approach to the cluster stability problem Volkovich, Z.; Barzily, Z.; Weber, Gerhard Wilhelm; Toledano-Kitai, D.; Avros, R. (Springer Science and Business Media LLC, 2012-03-01) Among the areas of data and text mining which are employed today in OR, science, economy and technology, clustering theory serves as a preprocessing step in the data analyzing. An important component of clustering theory is determination of the true number of clusters. This problem has not been satisfactorily solved. In our paper, this problem is addressed by the cluster stability approach. For several possible numbers of clusters, we estimate the stability of the partitions obtained from clustering of samp...
Some results on cooperative interval games ALPARSLAN GÖK, Sırma Zeynep (Informa UK Limited; 2014-01-02) Uncertainty is a daily presence in the real world. It affects our decision-making and may have influence on cooperation. On many occasions, uncertainty is so severe that we can only predict some upper and lower bounds for the outcome of our actions, i.e. payoffs lie in some intervals. A suitable game theoretic model to support decision-making in collaborative situations with interval data is that of cooperative interval games. Solution concepts that associate with each cooperative interval game sets of inte...
Capturing knowledge in construction projects: Knowledge platform for contractors Kivrak, Serkan; Arslan, Gokhan; Dikmen Toker, İrem; Birgönül, Mustafa Talat (American Society of Civil Engineers (ASCE), 2008-04-01) Managing knowledge effectively is critical to the survival and advance of a company, especially in project-based industries such as construction. However, capturing knowledge in construction projects is a tedious task, as knowledge is usually experience based, tacit, and hard to pass on to others. In this study, a survey was carried out among eight leading Turkish construction contractors that are operating within the international construction market. The specific objectives of this survey are to find out ...
Elicitation, prioritisation, observation: a research model to inform the early design phases with child-centred perspectives Süner, Sedef; Erbuğ, Çiğdem; Department of Industrial Design (2018) As children have become active users of diverse range of products and systems, the study of the experiences of child-users has become a specialised field of research, especially in the field of child-computer interaction. This has led to the recognition of children as a special user group with needs and interests different than that of adults. Incorporating child-driven perspectives into early design space is vital to inform the development of design concepts which can deliver meaningful interactions. Howev...
