Security analysis of advanced encryption standard (AES) for image encryption

Küçükbacak, Rıdvan

Abstract In recent years, there have been major advancements in multimedia technologies and accordingly, file transfer over the internet has become extremely frequent. However, some security issues can occur in the internet, since it is a very insecure channel. To preserve the privacy and security of multimedia data transmitted over the internet, a number of encryption algorithms have been developed. This research presents a methodology for examining practically used image processing encryption algorithms. To measure the quality of encoded images, a number of factors such as correlation coeffi ...Daha fazlası

Increasing importance of global value chain Turkey's foreign trade comparative analysis

Akmanlar, Nur

The global value chain has increased its importance with the spread of foreign trade between countries. As a result of this situation, it has provided serious economic returns to the countries. Countries that use the global value chain effectively have become rich in this process. In this study, the comparison of foreign trade between BRIC countries and Turkey has been examined through Grubel Lloyd index. Through this Grubel Lloyd index, the economic effects of the global value chain on the Turkish economy and BRIC countries are detailed. The increasing importance of global value chain, which ...Daha fazlası

Whatever singularity: queering the ‘quodlibet’ in the well of loneliness and oranges are not the only fruit

Yararoğlu, Semih

The aim of this thesis is to propose a hypothetical community for queer people of 20th century England depicted in two novels: Radclyffe Hall’s The Well of Loneliness (1928) and Jeanette Winterson’s Oranges Are Not the Only Fruit (1985) through Agamben’s idea of community. This study also intends to investigate the issue of the queer people in the 20th century, while demonstrating that the oppression of homosexual people has not changed despite the fact that one of the two novels is written at the beginning and the other at the end of the twentieth century. Suggesting a community to the queer ...Daha fazlası

‘The Other’ at the border: literary sieges and identity construction

Bakkalsalihoğlu, Fatma Gözde

In the 20th century, the issue of creating a national identity and fashioning the self gained significant importance as a consequence of the increasing nationalist movements and establishment of the unitary states with the collapse of empires. To create a collective identity consciousness in society, literature was utilized as one of the mediums, as it can be used in the service of different ideologies. First published in 1899, Eclipse of the Crescent Moon (Egri Csillagok) by Géza Gárdonyi focuses on creating the Hungarian national identity through the Turks, whereas The Siege (Kështjella) by ...Daha fazlası

The effects of climate change on financial markets

Günışık, Gündüz Can

There is a critical relationship between climate change and financial markets. In this study, temperature change values are used to examine the impact of climate change on agriculture, banking, investment, and insurance sectors. The study determines the relationship between temperature changes and agriculture, banking, investment, and insurance indices in BIST by regression analysis. The results show that climate change has different impacts on different sectors. While the agricultural sector is more sensitive to temperature changes, its impact on the bankingand investment sectors may be more ...Daha fazlası

Fact-checking in the postmodern era

Balcı, Habib

In this thesis, we have tried to evaluate the concept of fact-checking, which constructs a new discourse in the media industry in parallel with the concept of post-truth, and within this framework, we have tried to evaluate how fact-checking channels evaluate the concepts of truth and lies within the framework of Postmodern thought, as well as focusing on the question of whether fact-checking tools, which claim to be a fact-truth, are the new gate-keepers of the new media and which truths or lies these platforms open their eyes to and which ones they close to (such as peak a boo). Indeed, Post ...Daha fazlası

Impact of the energy issue on Turkey’s Easten Mediterranean policy

Öztürk, Gökçe

Energy and its security is one of the most important issues in making of a foreign policy. Seeking of alternative energy resources and having their own share, stirred the Eastern Mediterranean with the discoveries of hydrocarbon reserves. The fact that Turkey is highly dependent on energy resources, that its consumption rates are increasing year by year, and that it aims to be the energy hub that transfers energy to Europe, has also led Turkey to want to be part of the energy equation that is emerging in the Eastern Mediterranean. Although the parties to this equation excluded Turkey. Turkey t ...Daha fazlası

Image to Music: Cross-Modal Melody Generation Through Image Captioning

Kaplan, Alper

Advances in machine learning in recent years have also been seen in computationally creative systems. Interest in machine-generated artifacts paved a way for creative models to evolve as such. But the earlier methods mostly explored a one domain approach and cross-modal learning has stayed relatively unexplored. Thus, the direct mapping between modalities for cross-modal creative models is not fully explored. This work proposes a novel methodology for generating symbolic music through images by directly mapping their features. A CNN encoder and deep stacked LSTM decoder are the base models as ...Daha fazlası

An instructional design for new cognitive structure construction in native language on second language learning

Erden, Münire

This study aims to design a second language instruction through the construction of new cognitive structures in the mother tongue and to determine its effect on the learner's cognitive load and achievement in learning complex structures. The study was undertaken in a public university in Istanbul with 79 prep school students and designed as a quasi-experimental study. A subjective cognitive load scale developed by Paas (1992) and an achievement test were utilized as the data collection tools. A covariance analysis (ANCOVA) was employed to determine student achievement between the experiment an ...Daha fazlası
