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

The past and current state of geometric abstract art

Eroğlu, Osman Selçuk

Following an introduction to abstract art this thesis study focuses on the geometric abstract art which emerged with the onset of abstract art in three time periods. In the first section which encompasses a time frame of approximately forty five years between the onset of abstract art in the begining of the 20th century and the end of World War II it is discussed how artists like Kandinsky and Malevich made a difference by breaking off from the convention and thus contributed to the existence of the geometric abstract art. In the second section which covers a time frame between the emergence o ...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

Anonim şirketlerde kâr payında i̇mtiyaz

Aydın, Ayşe Güneş

6102 sayılı Türk Ticaret Kanunu (TTK) md.331’de anonim şirketlerin, yasal düzenlemelere aykırı olmamak kaydıyla her çeşit ekonomik amaç ve konu için kurulabileceği belirtilmiştir. Yasada yer alan düzenlemeden de anlaşılacağı üzere anonim şirketlerin nihai amacı kazanç elde etmektir. Dolayısıyla pay sahiplerinin en önemli mali hakkının “kâr payı hakkı” olduğunu söylemek yerinde olacaktır. Genel kabul gören kurala göre pay sahipleri, anonim şirketin elde ettiği kazançtan pay sahiplikleri oranında yararlanacaklarsa da TTK md.478 ile kâr payına imtiyaz tanınmasının önünün açılması sayesinde bazı p ...Daha fazlası

Kırım’da yaşanan i̇lk Rus i̇stilası 1736

Budak, Rüçhan

1699 Karlofça Antlaşması sonrası Osmanlılar, erken XVIII. yüzyıla kaybedilen toprakları geri alma politikası takip etmişti. Bu politika gereği 1711 yılında Azak kalesini Ruslardan ve 1714 yılında Mora yarımadasını da Venedik’ten geri almıştı. 1736 senesine gelindiğinde Ruslar, Karadeniz’in kuzeyine hâkim olabilmek için Azak kalesini ele geçirip Kırım Hanlığı’nı ilhak etme politikası takip ettiler. Osmanlılar ile Ruslar arasında cereyan eden bu savaşta Kırım Hanlığı tarihinde ilk kez yabancı güçler tarafından istilaya maruz kalmıştı. 1736 senesinde Ruslar adına Mareşal Münih, Kırım’ı istila ede ...Daha fazlası

The influence of community size on constituent order: A comparison between emerging and conventionalized sign languages

Ticau, Valeria

The current study examines the effect of community size on constituent order by comparing conventionalized sign languages (TID and LIBRAS) and emerging sing languages (CTSL and CENA) from two different countries. When the relevant literature is examined, it is observed that languages that emerge in communities with larger populations tend to have a more uniform structure, while languages that emerge in smaller and closed-knitcommunities exhibit greater diversity regarding their constituent order. Data was collected through an elicitation task comprised of 30 short video clips containing senten ...Daha fazlası

Adrenergic modulation of melanocortin pathway by hunger signals

Yılmaz, Bayram | Yavuz, Yavuz

Norepinephrine (NE) is a well-known appetite regulator, and the nor/adrenergic system is targeted by several anti-obesity drugs. To better understand the circuitry underlying adrenergic appetite control, here we investigated the paraventricular hypothalamic nucleus (PVN), a key brain region that integrates energy signals and receives dense nor/adrenergic input, using a mouse model. We found that PVN NE level increases with signals of energy deficit and decreases with food access. This pattern is recapitulated by the innervating catecholaminergic axon terminals originating from NTSTH-neurons. O ...Daha fazlası
