Demand and supply planning for Covid-19 vaccine in Turkey with an anti-vaccine survey
The Covid-19 virus, which affects many people, continues in a very contagious state. Vaccination is necessary to end this pandemic period, which everyone wants to end as soon as possible. The studies in the literature ... -
An investigation into mechanical and thermal characteristics of synthetic jet actuators with compact packaging
Işıl, Onuralp (2021-01-05)Cooling systems have been one of the most important elements in packaged electronics due to their inseparable relation with performance. Processors, light emitting diodes (LED), servers, advanced communication systems, ... -
N-hop influence maximization problem under deterministic linear threshold model
The Influence Maximization Problem (IMP) finds a set of highly influential nodes within a social network in order to maximize the spread of influence. We consider that people can have influence on their direct (1-hop), ... -
Parametric and non parametric models for stochastic next day operating room scheduling
Sevindik, Ömer Hikmet (2018-01)Operating rooms are the resources that generate the most part of the revenue of hospitals. On the other hand, they generate the most part of the expenses, as well. Because of the uncertainty of surgery durations, scheduling ... -
A real life operating room scheduling problem
Alper, Gülşah (2015-08)A real life operating room scheduling problem is studied using a data set from a leading hospital, Hospital X, in Turkey. After analyzing the real data, we solve daily operating room scheduling problems by mixed integer ... -
A robust longitudinal model for song popularity: a cross-cultural study
Çimen, Ahmet Can (2021-08-16)Usage of new generation music streaming platforms such as Spotify and Apple Music has increased rapidly in the last years. Understanding the music preferences of the user base is valuable for these firms, translating into ... -
Rolling look-ahead approaches for optimal classification trees
Classification trees have gained tremendous attention in machine learning applications due to their inherently interpretable nature. Current state-of-the-art formulations for learning optimal binary classification trees ... -
A smart cloud platform service for socialized travel and transportation with mobile support
Yazıcı, Yaprak Ayazoğlu (2013-09)It is now clear that social networking services are evolving towards mobile web applications and continuous location sharing is also becoming a trend. In this evolution, we believe that the next step will be complete and ... -
Solving a modified TSP problem by a greedy heuristic for cost minimization
Çal, Murat (2017-06)Photographing a large area in an instant is only made possible by satellites. Satellites are able to help reducing the time required for the photographing/monitoring process, however, satellite images are not available all ... -
Speaker adaptation with deep learning for text-to-speech synthesis systems
End-to-end (e2e) speech synthesis systems have become popular with the recent introduction of letter-to-spectrogram conversion systems, such as Tacotron, that use encoder-decoder-based neural architectures. Even though ... -
Stochastic scheduling of operating rooms and reusable medical devices: a simulation optimization approach
Farajkhah, Seyyed Kian (2019-08-08)Health care expenditures are expected to grow every year, and more than 40% of a hospital's total expenses and revenues are generated by surgical surgeries. One of the major resources required during surgeries are reusable ...
