Hierarchical representation of video sequences for annotation

MENDİ, Engin

Video annotation is an important issue in video content management systems. Rapid growth of the digital video data has created a need for efficient and reasonable mechanisms that can ease the annotation process. In this paper, we propose a novel hierarchical clustering based system for video annotation. The proposed system generates a top-down hierarchy of the video streams using hierarchical k-means clustering. A tree-based structure is produced by dividing the video recursively into sub-groups, each of which consists of similar content. Based on the visual features, each node of the tree is ...Daha fazlası

Tagging accuracy analysis on part-of-speech taggers

YUMUŞAK, Semih | DOĞDU, Erdoğan | KODAZ, Halife

Part of Speech (POS) Tagging can be applied by several tools and several programming languages. This work focuses on the Natural Language Toolkit (NLTK) library in the Python environment and the gold standard corpora installable. The corpora and tagging methods are analyzed and compared by using the Python language. Different taggers are analyzed according to their tagging accuracies with data from three different corpora. In this study, we have analyzed Brown, Penn Treebank and NPS Chat corpuses. The taggers we have used for the analysis are; default tagger, regex tagger, n-gram taggers. We h ...Daha fazlası

Gabion Tipi Dayanma Yapıları

URAY, Esra | TAN, Özcan

Malzeme üretim ve kaplama teknolojilerindeki gelişmeler sonucu gelişmiş ülkelerde daha yaygın uygulama alanı bulan gabion tipi dayanma yapılarının birçok durumda daha ekonomik olmalarına karşılık, ülkemizde çok yaygın kullanılmadıkları görülmektedir. Bu makalede; gabion tipi yapılar ve başlıca uygulama alanlarının tanıtılması, avantaj ve dezavantajlarının belirlenmesi, tasarım ve uygulamalarda dikkat edilmesi gerekli hususlar üzerinde durulmuştur.

Ergenlik Döneminde Öz Şefkatin Saldırganlık Davranışlarına Etkisi

TUNCER KAYHAN, Selda

Bu araştırmanın temel amacı; ergenlik döneminde öz şefkatin saldırganlık davranışlarına etkisinin incelenmesidir. Bu bağlamda ergenlik döneminin gelişimsel özelliklerinin derinlemesine incelenmesi, saldırganlığa neden olan faktörlerin sonuçlarının belirlenmesi ve ergenlerin öz şefkat becerilerinin demografik özellikler ile ilişkisinin ortaya konmasını sağlamaktır. Ergenlik döneminde birey bedenindeki ve zihnindeki hızlı gelişmelere ayak uydurmakta zorlanabilmekte ve bu karışıklığı dışarıya saldırganlık olarak yansıyabilmektedir. Saldırgan tutumlar ergenlik döneminde artış göstermektedir. Diğer ...Daha fazlası

Kuzey Avrupa ve Latin Amerika ülkeleri arasında gelir dağılımı adaletsizliği açısından ekonometrik bir analiz

KALAYCI, Salih | ÖZTÜRK, Ayhan | GÜNDÜZ, Mehmet Akif

Belirli bir dönemde kazanılan gelirlerin, bireylerin oluşturduğu gruplarca paylaşılması anlamına gelen gelir dağılımı konusunda yaşanan adaletsizlik bütün dünyada büyük bir sorun haline gelmektedir. Bu bağlamda, hem gelişmiş, hem de gelişmekte olan ülkeler açısından hayati önem taşımaktadır. Gelir dağılımı adaletsizliği uluslararası boyutta olabildiği gibi, ülke içinde çeşitli bölgeler arasında, hatta bireyler arasında da olabilmektedir. Çalışmamızda 2004 – 2014 yılları için panel veri analizi uygulanmış ve makro bağlamda Kuzey Avrupa ülkeleri ile Latin Amerika ülkeleri arasındaki gelir dağılı ...Daha fazlası

Line × tester analysis of stomatal conductance, chlorophyll content, photosynthetic efficiency, and transpiration rate traits in maize

ÖZDEMİR, Elif | SADE, Bayram

This study evaluated seven inbred lines of maize (Zea mays L.), three testers and 21 hybrids produced by line × tester mating design. Stomatal conductance, chlorophyll content, photosynthetic efficiency, and transpiration rate traits of parents and progenies were observed. The study was conducted in Konya, in the mid-Anatolian region of Turkey. The mean values of the stomatal conductance, chlorophyll content, photosynthetic efficiency, and transpiration rate measurements were evaluated using Duncan’s multiple range test for grouping parent and offspring groups. The variance for general combini ...Daha fazlası

The validity of eight neoclassical facial canons in the Turkish adults

KARACA SAYGILI, Ömür | ÇINAR, Selçuk | GÜLCEN, Burak | ÖZCAN, Emrah | KUŞ, İlter

The neoclassical canons were used to define the proportions between various areas of the head and face. Therefore, this study was done to establish the neoclassical canons of facial proportions in Turkish adults. A total of 200 healthy adults 20 to 35 years of age were examined. Using anthropometric landmarks, 5 horizontal and 9 vertical direct measurements were made on the faces with a sliding calliper. Results have been compared with 8 neoclassical facial canons. When comparing between sexes, a significant difference has been found in all measurements except the upper facial width, left eye- ...Daha fazlası
