    Advances in Model-Based Testing of Graphical User Interfaces
    (Academic Press Inc., 2017) Belli, Fevzi; Beyazıt, Mutlu; Beyazıt, Mutlu; Tuğlular, Tuğkan; Budnik, Christof J.; Belli, Fevzi; Tuğlular, Tuğkan; 03.04. Department of Computer Engineering; 03. Faculty of Engineering; 01. Izmir Institute of Technology
    Graphical user interfaces (GUIs) enable comfortable interactions of the computer-based systems with their environment. Large systems usually require complex GUIs, which are commonly fault prone and thus are to be carefully designed, implemented, and tested. As a thorough testing is not feasible, techniques are favored to test relevant features of the system under test that will be specifically modeled. This chapter summarizes, reviews, and exemplifies conventional and novel techniques for model-based GUI testing.

    Control Methods for a Teleoperated Endoscope Robot
    (Springer Verlag, 2019) Işıtman, Oğulcan; Işıtman, Oğulcan; Dede, Mehmet İsmet Can; Dede, Mehmet İsmet Can; 01. Izmir Institute of Technology; 03.10. Department of Mechanical Engineering; 03. Faculty of Engineering
    In this study, control of a endoscope robot for the pituitary gland surgery is presented. This co-worker robot has non-backdrivable actuation system with external brakes on the actuators. Since it is required to move in a constrained environment, which is the inside the nostrils in this case, modifications are required for the motion controller. In order to provide safe procedure, the maximum force and torque limits are defined for the real surgical case by using human cadaver head. By considering these limits and application specific requirements, a compliance controller is proposed and experimentally tested.

    Energetic and Exergetic Design Evaluations of a Building Block Based on a Hybrid Solar Envelope Method
    (Springer Verlag, 2018) Mert, Yelda; Saygın, Nicel; Saygın, Nicel; 02.03. Department of City and Regional Planning; 02. Faculty of Architecture; 01. Izmir Institute of Technology
    To achieve sustainable development, there needs to be a focus on decreasing use of non-renewable energy sources and greenhouse gas emissions. In this regard, many studies focus on the strong relationship between energy and the environment. This study aimed to introduce the exergy analysis method into the urban planning field to find out the amount of exergy, rather than energy, that can be conserved in a building block when a solar envelope-based design is applied. In addition to the known energy-efficient design parameters, a criterion for the solar envelop method is integrated into a single method. This hybrid method includes taking into account the requirements for orientation, spacing, landscaping, and building form, as well as the building height properties as proposed in the solar envelop method. The solar envelop method depends on understanding the changing position of the sun throughout the day and year. If this dynamic behavior can be a factor in the design of an urban area, environmental friendliness, sustainability, and reduced energy consumption can comprehensively be achieved in cities.

    Thermodynamic Performance Evaluation of a Geothermal Drying System
    (Springer Verlag, 2014-01) Helvacı, Hüseyin Utku; Helvacı, Hüseyin Utku; Gökçen Akkurt, Gülden; Gökçen Akkurt, Gülden; 01. Izmir Institute of Technology; 03.06. Department of Energy Systems Engineering; 03. Faculty of Engineering
    Renewable energy sources such as geothermal energy can be used in drying processes as a heat source due to the high energy costs of fossil fuels. In this study, geothermal cabinet type dryer was constructed and situated in Balcova-Narlidere Geothermal Field, Turkey where the clean city water of district heating system is used as an energy source for the dryer. The dryer was tested on site for drying of olive leaves and energy and exergy analyses of the drying process conducted under two cases: Case 1. Exhaust air was rejected to the environment. Case 2. A portion of exhaust air was re-circulated. Energy Utilization Ratio (EUR) was determined as 7.96 for Case 1 and 50.36 for Case 2. The highest rate of exergy destruction occurred in the fan, followed by heat exchanger and the dryer, accounting for 0.2913, 0.05663 and 0.0115 kW, respectively. Exergetic efficiency of the drying chamber was calculated as 89.66 %. Re-circulating the exhaust air decreased the exergy value at the outlet of the dryer from 0.1013 to 0.08104 kW, indicating that re-using the air increases the performance of the dyer.
