Master Thesis Evaluation of Scheduling Architectures for Osek/Vdx Compliant Hard Real-Time Operating Systems(Izmir Institute of Technology, 2020) Saydam, Berkay; Ayav, TolgaTechnological advancements are reflected to the vehicles as well, but it brings the challenge of adding new functionalities to vehicles without compromising safety. Tasks are used to provide functionalities which are used in car. These tasks have different characterictics. Safety and performance are two main criteria to determine characterictic of tasks. Characteristics of tasks can be classified according to their safety levels which are known as Automotive Safety Integrity Levels. Designing of hardware and software and also testing them is a long progress in automotive industry. Any changes on the design of hardware is quite costly when an ECU began to be used in field. According to my hypothesis, scheduling algorithms which are used by Central Processing Unit to determine sequences of task executions, should be well known. Besides, designing of hardware and software should be done according to these characteristics and algorithms. If not, tasks will cause serious problem like missing deadline for safety-critical component. In this thesis, the scheduling architectures are evaluated and they are determined which scheduling architectures should be used for which purpose. Besides, the advantages and disadvantages are explained.Master Thesis Computer Aided Design Program "çizen" and Designers Interaction and Efficiency Analysis; Development of Intelligent Interface Suggestions(Izmir Institute of Technology, 2020) Zengin Bintaş, Gül Çiçek; Erkarslan, ÖnderSoftware is not only a rapidly developing and indispensable tool today but also the most prominent driving force of digital transformation. Thanks to the innovation studies carried out in the software of these programs, the productivity growth is achieved in the design processes, and the errors arising from the design could be reduced to a minimum. In Turkey, since 2010, working on CAD development have been initiated; the domestic and national program called “ÇİZEN,” has been developed for sheet metal forming design. In this study, new techniques and innovative methods were performed in the ÇİZEN program, which was developed and personalized specifically to a particular sector and then, User Experience Survey was conducted. The study aimed to design a simple and intelligent interface by clearly determining the needs and expectations of sheet metal designers and the user's program experience. Within the scope of this objective, user experience surveys were conducted with the participation of 14 users. In this context, the users were asked pre-configured and open-ended questions, and by giving the users specific tasks, the focus points in the program were revealed with heat maps through the Eye Tracker device. As a result of the finalization of pre-test studies and obtaining eye-tracking data, the final-test phase was initiated; and after the general opinions about the program were received, System Usability and Nonverbal Pictorial Scale research was conducted. The data obtained from the research results were interpreted, evaluated, and suggestions were developed under three main headings: productivity, simplicity/functionality, and interface.
