Conference Object A Solution To the Adhesion Problem of Oxide Thin Films on Zinc Selenide Optical Substrates(Soc Vacuum Coaters, 2016) Cosar, M. B.; Aydogdu, G. H.; Batman, H.; Ozhan, A. E. S.Zinc selenide optical substrates have high transparency within the 0.5- to 14.0-mu m wavelength range. This makes them an attractive candidate for multiband imaging applications in optical components. In order to minimize reflection loss in visible, near-infrared, and mid-infrared applications, zinc selenide lenses are coated with multi-layered oxide thin films by physical vapor deposition method or ion beam deposition. In this study, a four-layer anti-reflective filter at 1.064 gm and between 3.6 and 4.9 gm is applied to zinc selenide using an ion beam deposition system. The filter is used for a dual-beam optical application. The filter is composed of metal oxide layers that have an adhesion problem on zinc selenide. In order to solve this adhesion problem they were heat-treated at 300 degrees C for varying amounts of time prior to metal oxide coating. Treated samples were characterized in terms of their roughness, contact angle, morphology, refractive index, transparency, crystallography and chemical composition. Results show that it is possible to manufacture durable oxide thin film coatings on zinc selenide, by using a well-designed pre-treatment processes.Conference Object Citation - Scopus: 50Internet-Of Smart Transportation Systems for Safer Roads(Institute of Electrical and Electronics Engineers Inc., 2020) Derawi,M.; Dalveren,Y.; Cheikh,F.A.From the beginning of civilizations, transportation has been one of the most important requirements for humans. Over the years, it has been evolved to modern transportation systems such as road, train, and air transportation. With the development of technology, intelligent transportation systems have been enriched with Information and Communications Technology (ICT). Nowadays, smart city concept that integrates ICT and Internet-of-Things (IoT) have been appeared to optimize the efficiency of city operations and services. Recently, several IoT-based smart applications for smart cities have been developed. Among these applications, smart services for transportation are highly required to ease the issues especially regarding to road safety. In this context, this study presents a literature review that elaborates the existing IoT-based smart transportation systems especially in terms of road safety. In this way, the current state of IoT-based smart transportation systems for safer roads are provided. Then, the current research efforts undertaken by the authors to provide an IoT-based safe smart traffic system are briefly introduced. It is emphasized that road safety can be improved using Vehicle-to-Infrastructure (V2I) communication technologies via the cloud (Infrastructure-to-Cloud - I2C). Therefore, it is believed that this study offers useful information to researchers for developing safer roads in smart cities. © 2020 IEEE.Conference Object Citation - WoS: 6Simulation-Based Environments for Surgical Practice(Ieee, 2017) Dalveren, Gonca Gokce Menekse; Cagiltay, Nergiz Ercil; Ozcelik, Erol; Maras, HakanModeling and simulation environments provide several insights about the real situations such as endoscopic surgery. Endoscopic surgery requires both hand skills, so, understanding the effect of using dominant or non dominant hand on mental workload is important to better design, develop and implement modeling and simulation environments to support real-life implementations of surgical procedures. This experimental study presents a simulation application of eye-tracking approach to understand mental workload in different hand conditions: dominant hand, non-dominant hand and both hand. The results of the study show that, performing simulated surgical tasks by both hands compared to dominant hand, increases mental workload which is evident by higher pupil size. Accordingly, to manage the mental-load problems of surgeons while performing complex tasks that require both hand usage simulation-based environments can be used. Consequently, collection of detailed information such as eye-data, can give several insights about the behaviors of the surgeons. Also, their required skills can be improved by development of simulation and training environments.Conference Object Citation - Scopus: 1Ontology Based Virtual Enterprise System Domain Modeling(DEStech Publications Inc., 2014) Lotfi Sadigh,B.; Ünver,H.Ö.; Dogdu,E.; Kiliç,S.E.A virtual enterprise (VE) is a product oriented temporary consortium which forms a collaboration platform to fulfil a specific common purpose (typically to create a product) by benefiting from various capabilities of multiple VE partner enterprises. VE lifecycle consists of 3 distinct phases including VE Formation, Operation and Dissolution. VE partner enterprises are selected from virtual breeding environment (VBE) based on specific criteria considering the new VE project specifications. In order to select the most appropriate partners for the forthcoming VE project, it is required to have comprehensive information regarding the VBE members, their current conditions, capabilities, capacities and their past performances. This database continuously changes and it is dynamic. Ontologies and the corresponding knowledge bases provide the best tools for modelling such complex domain knowledge and highly dynamic data requirements. Ontologies not only help model and capture complex domain knowledge, but also improve the sharing and reusability of data and knowledge providing a suitable environment for software agents and human communications. The VE system must be able to demonstrate what types of resources exist, where they are located, and how much resource capacity is available to be used by the consortium. In this paper a pilot Virtual Enterprise system model developed for OSTIM organized industrial park in Ankara will be presented in detail. The objective of this system model is to enable SMEs in the region to collaborate effectively in order to produce eco-friendly high value added products. © Copyright 2014 by DEStech Publications, Inc.

For this purpose, a fast Hough transform approximation by use of a sliding mask is developed. The approximation decomposes the lines at different orientations into distinct bitplanes. Barcode localization is achieved by considering the high density locations in the bitplanes via morphology and profiling. The time complexity of the proposed approximation is lower than the previously proposed fast Hough transform, though it achieves the equal performance in localization of barcodes.Conference Object Citation - WoS: 8Using E-Learning in Enterprise Resource Planning (erp) Training: a Case Study To Assist Curriculum Designers in Turkey(Elsevier Science Bv, 2014) Dalveren, YaserThis article presents results of a research on integration of Enterprise Resource Planning (ERP) e-Learning model into the university curriculum.

Wilkins (1972) asserted that "without grammar very little can be conveyed, without vocabulary nothing can be conveyed". Since the pioneering research of Michael West (1953), many academic or general wordlists have been published in English or in other languages. On the other hand, the lack of an Academic Turkish Wordlist which meets the academic criteria such as being collected from a valid corpus has made this research necessary in the field of teaching Turkish as a foreign language. This study aims to investigate the academic vocabulary that any Turkish language learner should have before starting to study at undergraduate programs offering Turkish medium instruction. An academic corpus derived from fifty-seven textbooks was formed so as to discover the Academic Turkish Wordlist. There were 4032442 tokens in the academic corpus and various computer software programs some of which were written for the current study were used in order to acquire the academic wordlist. Lemmas, or the groups of lexical forms with the same stem that belong to the same word class, (Francis & Kucera, 1982) were used for the creation of the Academic Turkish Wordlist. Moreover, the most frequent 11000 words from Turkish National Corpus were used to make a list of words to be excluded from the academic corpus and the final version of the Academic Turkish Wordlist contained 1010 lemmas. The Academic Turkish Wordlist covered 32% of the academic corpus and it is evident that knowing the words in the academic wordlist will help undergraduate foreign students studying Turkish improve their academic language skills, especially reading comprehension. The Academic Turkish Wordlist could be utilized in various ways: 1) to check out language learning materials in order to find out how many low/high frequency words they contain 2) to compare students' writings in terms of how many academic words they are able to use 3) to prepare proficiency exams 4) to revise their language program in order to include more academic words to prepare their students for undergraduate programs.
