Adaptive domain-specific service monitoring
Ünsal, Arda Ahmet (2014-01)We propose an adaptive and domain-specific service monitoring approach to detect partner service errors in a cost-effective manner. Hereby, we not only consider generic errors such as file not found or connection timed ... -
Automated procedure clustering for reverse engineering PL/SQL programs
Altınışık, Metin (2016-05)Large software systems have to be decomposed into separate, modular units for providing appropriate abstractions and improving maintainability. There exist clustering techniques that are applied to provide such abstractions ... -
Combined aes + aegis architectures for high performance and lightweight security applications
Şahin, Furkan (2014-08)Günümüzde kriptografi banka kartlarından telefonlara, arabalardan haberleşme araçlarına ve bulut hizmetlerine kadar pek çok alana girdi. Digital bilgiyi yetkilendirilmemiş erişimlere karşı korumak için bir çok şifreleme ... -
Comparison of text-independent speaker verification systems in a multi-class, semi-automatic detection scenario
Yeşil, Fatih (2013-06)Performance of the speaker veri cation systems is typically measured based on their binary decision accuracy. Soft outputs of the systems are used mostly for calibration or multiple system combination purposes. However, ... -
Computational approaches to brain mechanisms of action recognition and emotion
Kırtay, Murat (2015-08)Through evolution living beings have gained unique features to deal with apparently easy but computationally expensive problems such as mate selection, learning sensorimotor skills and decision making. Thus, understanding ... -
Extending static analysis with application-specific rules by analyzing runtime execution traces
Ersoy, Ersin (2016-07)Static code analysis tools can generate alerts regarding only generic issues such as uninitialized variables. They cannot detect violations of application-speci c rules. Tools can be extended with specialized checkers that ... -
Fast, secure, and remote multiboot of FPGAs
Yıldız, Abdullah (2012-09)The purpose of this thesis is to develop an efficient framework to implement secure FPGA-based (Field Programmable Gate Array) systems. An FPGA is a reconfigurable device that has the ability to adapt the hardware during ... -
Fault masking as a service
Gülcü, Koray (2013-01)In service-oriented architectures, composite services depend on a set of partner services to perform their tasks. These partner services may become unavailable due to system and/or network faults, leading to an increased ... -
Fusion of subjective opinions through behavior estimation
Aycı, Gönül (2016-01)Information is significantly important in almost all decision-making process. A decision- maker agent collects information from diverse sources. Thus, it should correctly fuse opinions, which are shared from different ... -
A gamified lesson preparation system
Uzun, Necip Onur (2017-01)Good games are embedded with many elements that make them attractive to play. If lessons could also be gamified, they would cease to be boring and become attractive as well. This could result in students spending more time ... -
Generating runtime verification specifications based on static code analysis alerts
Kılıç, Yunus (2017-12)There are various approaches in order to find bugs in a software system. One of these approaches is static code analysis, which tries to achieve this goal by analyzing code without executing it. Another complementary ... -
High level synthesis for rapid design of video processing pipes
Güzel, Aydın Emre (2017-01)Pipelining concept is a fundamental technique in digital hardware design, which maximizes the clock frequency or minimizes the resources. Designing a pipelined Field Programmable Gate Array (FPGA) module using pipelined ... -
Hybrid job scheduling for improved shared cluster utilization
Koçak, Uğur (2014-01)Bu tezde, bilgisayar küme yapıları üzerinde hibrid iş yüklerinin birlikte işlenmesiyle ilgili modeller, sorunlar ve performans kazanımları incelenmektedir. Desteklenen kümeleme teknolojileri arasında MPI, Hadoop-MapReduce ... -
Improving models for model-based testing based on exploratory testing
Gebizli, Ceren Şahin (2014-08)Model bazlı test, test edilen sistemin modelleri sayesinde otomatik olarak test senaryoları oluşturulmasını sağlar. Bu modellerin doğruluğu ve tamlığı oluşturulan test senaryolarının etkinliğini belirler. Genelde manuel ... -
Location-based access control and trust in location estimation
Soyluoğlu, Berker (2017-01)With the introduction of touchscreen smartphones our way of life changed. Indie developers are in a rush to find the next big thing. Available sensors and the powerful mobile operating systems made location aware applications ... -
M-pick fixed-priority selection and muxing
Tosun, Mustafa (2017-01)In this thesis, we propose a class of logic architectures for multi-pick (m-pick) fixed-priority arbitration (FPA) and muxing. An m-pick FPA selects the m topmost requests out of n inputs with priority order. Arbiters ... -
Multi-pick round robin arbiter
Temizkan, Fatih (2012-08)In this thesis, we propose two multi(m)-pick Round Robin Arbiter (RRA) architectures. An m-pick RRA selects the m topmost requests out of n inputs with priority order indicated by an internally kept pointer (with an update ... -
Performance evaluation of unfolded sparse matrix-vector multiplication
Akgün, İbrahim Ümit (2015-01)Sparse matrix-vector multiplication (spMV) is a kernel operation in scientific com- putation. There exist problems where a matrix is repeatedly multiplied by many different vectors. For such problems, specializing the spMV ... -
Reproducing field failures based on semi-formal failure scenario descriptions
Karagöz, Gün (2015-06)Due to the increasing size and complexity of software systems, it becomes hard to test these systems exhaustively. As a result, some faults can be left undetected. Undetected faults can lead to failures in deployed systems. ... -
Risk-driven model-based testing
Kırkıcı, Abdulhadi (2018-05)Software is becoming larger and more complex in consumer electronics products. As a result, testing these products for reliability is becoming a major challenge. Traditional and manual testing activities are not effective ...
