Name, Last name: Gülseren Fedakar Gönül Signature : iv ABSTRACT FEATURE MODELING AND AUTOMATED ANALYSIS FOR AN EMBEDDED SOFTWARE PRODUCT FAMILY Fedakar Gönül, Gülseren M.Sc., Department of Computer Engineering Supervisor: Assoc. Dr. Halit Oğuztüzün August 2013, 132 pages In the context of software product line engineering, feature models are used for modeling variability and commonality in product families. This thesis presents a basic feature model for a commercial television set product family. This work consists of three stages. First, a feature model is constructed, based on the analysis of the product family requirements. The constructed model is supplemented with a feature glossary. FeatureIDE is used as the model editor. Feature attributes, not supported by FeatureIDE, are represented in the basic feature model by using additional features. Second, the feature model in XML format is converted into the schema of the analysis tool, using a custom parser developed for this purpose. Third, the model is analyzed by well-known analysis operations. FAMA is used as the analysis tool. Performance results are obtained. Finally, lessons learned from the whole effort are discussed. Keywords: Feature Modeling, Extended Feature Model, Software Product Lines, Commonality, Variability, Variability Management. iii ÖZ BİR GÖMÜLÜ YAZILIM AİLESİ İÇİN ÖZELLİK MODELLEMESİ VE OTOMATİK ANALİZİ Fedakar Gönül, Gülseren Yüksek Lisans, Bilgisayar Mühendisliği Bölümü Tez Yöneticisi: Doç. Dr. Halit Oğuztüzün Ağustos 2013, 132 sayfa Yazılım üretim bandı mühendisliği bağlamında, özellik modelleri ürün ailelerinde değişkenlik ve ortaklıkları modellemek için kullanılmaktadır. Bu tez, ticari bir televizyon sistemi ürün ailesi için basit bir özellik modeli sunar. Bu çalışma üç aşamadan oluşur. İlk olarak, ürün ailesinin gereksinimlerinin analizine dayanan bir özellik modeli oluşturulur. Oluşturulan model, özellik sözlüğü ile desteklenir. Model editörü olarak FeatureIDE kullanılır. Ek özellikler kullanılarak, FeatureIDE’de desteklenmeyen öznitelikleri, basit özellik modelinde gösterilir. İkinci olarak, bu amaca özel geliştirilen bir çözümleyici ile XML formatındaki özellik modeli, analiz aracının şemasına dönüştürülür. Üçüncü olarak, model tanınmış analiz işlemleri üzerinden analiz edilir. Analiz aracı olarak FAMA kullanılır. Performans sonuçları elde edilir. Son olarak, bütün çalışma sonucunda öğrenilen deneyimler tartışılır.

  • Predicting the Future of Broadcasting
    DIGITAL BROADCASTING Predicting the future of broadcasting P.A. Laven EBU Technical Director Will broadcasting be supplanted by the Internet? Will “convergence” lead to a single delivery system for multimedia services? Which broadcast delivery systems (terrestrial, satellite or cable) will become dominant for digital TV? Will the reduction in costs of computer hardware affect broadcasting? Will computers merge with TV sets? This article attempts to answer such questions, both by looking “sideways” at the world of computers and the Internet and by analyzing some technological trends. 1.

  • Types of BNC Connectors
    Types of BNC Connectors The BNC (Bayonet Neill–Concelman) connector is a miniature quick connect / disconnect radio frequency connector used for coaxial cable. It features two bayonet lugs on the female connector; mating is fully achieved with a quarter turn of the coupling nut. BNC connectors are most commonly made in 50 ohm and 75 ohm versions, matched for use with cables of the same characteristic impedance. The 75 ohm connector is dimensionally slightly different from the 50 ohm variant, but the two nevertheless can be made to mate. The 75 ohm types can sometimes be recognized by the reduced or absent dielectric in the mating ends but this is by no means reliable. There was a proposal in the early 1970s for the dielectric material to be coloured red in 75 ohm connectors, and while this is occasionally implemented, it did not become standard. The 75 ohm connectors are typically specified for use at frequencies up to 2 GHz. 75 ohm BNC connectors are primarily used in Video (particularly HD video signals) and DS3 Telco central office applications. Many VHF receivers use 75 ohm antenna inputs, so they often used 75 ohm BNC connectors. The 50 ohm connectors are typically specified for use at frequencies up to 4 GHz. 50 ohm connectors are used for data and RF. A 95 ohm variant is used within the aerospace sector, but rarely elsewhere. It is used with the 95 ohm video connections for glass cockpit displays on some aircraft. Compatibility The different versions are designed to mate with each other, and a 75 ohm and a 50 ohm BNC connector which both comply with the 1978 standard, IEC 169-8, will mate non-destructively.
