Mobile telecommunications industry has experienced high growth rates for the recent 30 years. Accordingly, forecasting the future of mobile telecommunications services is important not only for mobile operators but also for all stakeholders in this industry ranging from handset manufacturers to vendors. In this thesis, the diffusion of mobile telecommunications services in 20 countries from different regions around the world is examined for the period of 1981 to 2010 with special emphasis on Turkey, in order to address the uncertainty in optimal model selection. The Gompertz, logistic and Bass models are fitted to the observed data of mobile phone penetration by means of nonlinear least squares. The fitness accuracies of the models are evaluated based on root mean square error (RMSE). Empirical results show that S-shaped growth models are capable of explaining the diffusion of mobile telecommunications services. The findings also suggest that there is no superior model in defining the diffusion process and the most suitable model is country dependent. Finally, we observe that the diffusion in late entrant countries appears to be faster than pioneer countries and peak demands in mobile telephones occur during the period of 1999 to 2006, which suggests a remarkable multinational learning effect and significance of the transition into digital technology.

An Efficient graph-theoretical approach for interactive mobile image and video segmentation Şener, Ozan; Alatan, Abdullah Aydın; Department of Electrical and Electronics Engineering (2013) Over the past few years, processing of visual information by mobile devices getting more affordable due to the advances in mobile technologies. Efficient and accurate segmentation of objects from an image or video leads many interesting multimedia applications. In this study, we address interactive image and video segmentation on mobile devices. We first propose a novel interaction methodology leading better satisfaction based on subjective user evaluation. Due to small screens of the mobile devices, error ...
Semantic prefetching and caching in 5G Mehteroğlu, Can; Onur, Ertan; Department of Computer Engineering (2017) Recent popularity of mobile devices increased the demand for mobile network services and applications that require minimal delay. 5G mobile networks are expected to provide much lesser delay than the present mobile networks. One of the conventional ways for decreasing latency is caching content closer to end users. However, currently deployed methods are not effective enough. In this thesis, we propose a new astute caching strategy that is able to smartly predict subsequent user requests and prefetch necess...
Methods for location prediction of mobile phone users Keleş, İlkcan; Toroslu, İsmail Hakkı; Department of Computer Engineering (2014) Due to the increasing use of mobile phones and their increasing capabilities, huge amount of usage and location data can be collected. Location prediction is an important task for mobile phone operators and smart city administrations to provide better services and recommendations. In this work, we have investigated several approaches for location prediction problem including clustering, classification and sequential pattern mining. We propose a sequence mining based approach for location prediction of mobil...
TZAR – time zone based approximation to ring: an autonomous protection switching algortihm for globally resilient optical transport networks Düzgün, Fatih; Schmidt, Şenan Ece; Department of Electrical and Electronics Engineering (2016) Widespread deployment of new generation high-speed networks, developments in large capacity DWDM technologies, and continuous demand for increasingly resilient global Internet services necessitates a revision on optical transport networks. Considered to be one of the most promising recent phenomena in that sense, OTN is evolving to become a major core switching platform. In this thesis, we briefly present the progress in optical transport networking from hardware architecture and software hierarchy points o...
GUI testing of android applications: a systematic mapping Aydın, Muzaffer; Betin Can, Aysu; Garousi, Vahid; Department of Information Systems (2014) Popularity of mobile devices is increasing rapidly all around the world. These devices can be used on various systems which are commonly used by the society. These systems are predicted to overtake desktop platform's popularity in the near future. Therefore the quality of mobile applications has vital importance. High quality applications can only be developed with good testing environments. Considering that multi-featured mobile applications have complex user interfaces, we decided to focus on graphical us...
