Advances in Model-Based Testing of Graphical User Interfaces
(Academic Press Inc., 2017) Belli, Fevzi; Beyazıt, Mutlu; Budnik, Christof J.; 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.

Basic Strategies and Testing Methods To Develop Effective Edible Antimicrobial and Antioxidant Coating
(Elsevier, 2018) Yemenicioğlu, Ahmet; 03.08. Department of Food Engineering; 03. Faculty of Engineering; 01. Izmir Institute of Technology
Due to the continuous increase in microbial outbreaks originated form minimally processed and ready-to-use food [1,2], the active food packaging has become one of the top research topics in food science. A properly designed active packaging might increase the microbial safety or delay the spoilage of food (antimicrobial packaging), it might delay oxidative changes in food (antioxidant packaging), or it might help increasing functional properties of food by delivery of nutrients or bioactive substances to food surface in bioavailable form (bioactive packaging)
A Brief History of Silicene
(Springer Verlag, 2017-11) Cahangirov, Seymur; Şahin, Hasan; Le Lay, Guy; Rubio, Angel; 04.04. Department of Photonics; 04. Faculty of Science; 01. Izmir Institute of Technology
Research on silicene shows a fast and steady growth that has increased our tool-box of novel 2D materials with exceptional potential applications in materials science. Especially after the experimental synthesis of silicene on substrates in 2012 it has attracted substantial interest from both theoretical and experimental communities. Every day, new people from various disciplines join this rapidly growing field. The aim of this book is to serve as a fast entry to the field to these newcomers and as a long-living reference to the growing community. To achieve this goal, the book is designed to emphasize the most crucial developments from both theoretical and experimental point of view since the starting of the silicene field back in 1994 with the first theoretical paper proposing the structure of silicene. We provide the general concepts and ideas such that the book is accessible to everybody from graduate students to senior researchers and we refer the reader interested in the detail to the relevant literature. We now start with a brief history of silicene where we highlight, in the chronological order, the important works that shaped our understanding of silicene.

Calibration Study of a Continuously Variable Transmission System Designed for Phri
(Springer, 2020) Mobedi, Emir; Dede, Mehmet Ismet Can; 03.10. Department of Mechanical Engineering; 03. Faculty of Engineering; 01. Izmir Institute of Technology
Variable stiffness actuators (VSAs) have been used in many applications of physical human-robot interfaces (pHRI). A commonly employed design is the spring-based VSA allowing the user to regulate the output force mechanically. The main design criteria of these actuation systems are the adjustment of output force independent from the output motion, and shock absorbing. In our recent work, we implemented certain modifications on the two-cone friction drive continuously variable transmission system (CVT) so that the CVT can be employed in pHRI systems. Subsequently, the optimized prototype is developed. In this study, we introduce the prototype of this new CVT systems, and its force calibration tests. The results indicate that the manufactured CVT is capable of displaying the desired output force throughout its transmission ratio range within a tolerance.
Challenges Faced by Closed Basins From the Perspective of Water Resources: Case Studies From Türkiye
(Springer Nature, 2025) Kircicek, Nilufer Tirol; Gungor, Esra Bilgic; Baba, Alper; 03.03. Department of Civil Engineering; 03. Faculty of Engineering; 01. Izmir Institute of Technology
Closed basins form important hydrological systems that provide a variety of benefits to both the environment and humans. This chapter examines the current status of closed basins in Turkiye and analyzes the natural and anthropogenic environmental stressors affecting these regions. Two distinct case studies are covered in this chapter: the Konya Closed Basin (KCB) and the Karakuyu region. Konya Closed Basin has experienced severe drought and sinkhole issues as a result of misapplications and excessive water consumption. The severity and frequency of water-related problems are increasing day by day due to the impact of climate change in the region. Agricultural activity and irrigation needs are high in the Karakuyu region, which is considered a second case study and is a small part of the Kucuk Menderes River Basin. It is hoped that with improved management practices, Karakuyu will not experience the condition of KCB in the future. The final section outlines the recommended practices and precautionary measures for addressing issues associated with closed basins.

A Closed-Form Solution of Spatial Sliders for Rigid-Body Guidance
(Springer, 2013-10-16) Huang, Chintien; Huang, Weiche; Kiper, Gökhan; 03.10. Department of Mechanical Engineering; 03. Faculty of Engineering; 01. Izmir Institute of Technology
This paper presents a closed-form solution to the four-position synthesis problem by using a spatial slider, which is a spatial dyad of two perpendicularly intersected cylindrical joints. We utilize the dialytic elimination method to simplify the synthesis equations and to obtain a univariate ninth degree polynomial equation. Among the nine sets of solutions, two of them are infinite, and one is the displacement screw from the first position to the second position. Therefore, we have at most six real solutions that can be used to design spatial sliders for the four-position synthesis problem. A numerical example is provided in to demonstrate the validity of the solution procedure.
Control of the Particle Size and Purity of Nano Zinc Oxide
(Taylor & Francis, 2014) Özmıhçı Ömürlü, Filiz; Balköse, Devrim; 03.02. Department of Chemical Engineering; 03. Faculty of Engineering; 01. Izmir Institute of Technology
Effects of template, mechanical mixing and/or ultrasound mixing on the size of the ZnO crystals obtained by precipitation at 30 °C from aqueous zinc chloride and potassium hydroxide solutions were investigated by 2k factorial design. Precipitation method is employed to synthesize nano zinc oxide particles. Monodisperse nano ZnO having 29 nm particle size was produced by adding triethyl amine and applying simultaneously mechanical and ultrasound mixing. The surface area and the density of the powder were 21 m2/g and 4.8 g/cm3. It contains 5.2% impurities present as CO3-2 and bound OH- groups. Volumetric resistivity was found as 1.3 × 107ohm cm. Absorption spectrum of the powder showed absorption peak at 353 nm. The room temperature fluorescence spectrum of the powder revealed a strong and sharp UV emission band at 391 nm due to free exciton or bound exciton of ZnO and a weak and broad violet emission band at 405 nm due to zinc vacancies.

Design and Optimization of Fiber Composites
(Elsevier, 2017) Aydın, Levent; Artem, Hatice Seçil; 03.10. Department of Mechanical Engineering; 03. Faculty of Engineering; 01. Izmir Institute of Technology
In engineering, design, and optimization processes are very important issues to establish sustainable engineering systems. Compared to isotropic materials, it is necessary to deal with more complicated mathematical models that address the material anisotropy for fiber-reinforced composites. Due to the unique characteristics of fiber-reinforced composite materials such as different directional properties, interlaminar stresses, less notch sensitivity, and having positive and negative coefficients of thermal expansion, they require more material constants for characterization of the hygrothermomechanical responses. Therefore, the design process of composites for the effort required or the benefit desired has to be systematic, which includes innovative approaches to synthesize alternative solutions. In this regard, the main goal of all such attempt is relevant to reach minimizing the effort required or to maximize the desired benefit.

Design of a Teleoperation Scheme With a Wearable Master for Minimally Invasive Surgery
(Springer, 2019) Ateş, Gizem; Majani, Ronny; Dede, Mehmet İsmet Can; 03.10. Department of Mechanical Engineering; 03.04. Department of Computer Engineering; 03. Faculty of Engineering; 01. Izmir Institute of Technology
Minimally invasive surgery is increasingly being preferred over conventional surgery, however many problems still persist in longer surgeries such as pituitary surgeries, where surgeons are still required to hold an endoscope in their hand for prolonged periods of time. Many modern approaches have recently been proposed in literature to reduce the surgeon’s effort. In this paper we extended upon these previous attempts and presented a promising solution; a real time teleoperation scheme with 3 different modes of operation, composed of a wearable ring system that captures and transmits voluntary hand motions over a wireless connection to a slave system. Accordingly, this slave system processes the received data to generate velocity demands for the robot endoscope controller. Finally, the feasibility of the proposed modes of operation are demonstrated and compared by measuring their learning curve and effort by running a set of training simulations on human subjects.
An Effect of Climate Change: Increased Health Risks Due To Arsenic in Drinking Water - the Case of İzmir, Turkey
(Nova Science Publishers, Inc., 2010) Sofuoglu, S.C.; Sofuoglu, A.; 03.02. Department of Chemical Engineering; 03. Faculty of Engineering; 01. Izmir Institute of Technology
Our previous research (Kavcar et al., 2009) has shown that tap water arsenic concentrations in the City of İzmir, Turkey, was of concern as arsenic in 15 of 37 (41%) of the tap water samples (collected in the year 2004) exceeded the Turkish drinking water standard of 10 µg/L (TMH, 2005). The median, mean, and 95th percentile concentrations were 2.9, 12.0, and 42.0 µg/L, respectively. The violations of the standard were in three districts, i.e., Bornova, Çiğli, and Karşıyaka, that were served primarily by groundwater sources. The concentrations in other districts were below the standard. However, concentrations less than the standard may be associated with a carcinogenic risk that is greater than the acceptable risk level of one in ten thousand depending on the level of exposure, mainly, daily drinking water intake rate and body weight. This was the case for the City of İzmir as lifetime carcinogenic risks exceeded the acceptable level for 19 of the 37 participants (51%). As the result of the above cited research, the local government has shut-down a number of groundwater wells as a mitigation measure. In turn, the concentrations were brought down to <15 µg/L in the three districts by increasing the proportion of surface water supplied from Tahtalı Reservoir. However, climate change has been affecting the region. The water volume in the resevoir was dropped below 5% in 2008. As a result, the arsenic contaminated wells were brought back into the service, causing a sharp increase in the arsenic concentrations, this time all around the city, measured by the local health authority. İzmirians who can not afford to buy bottled drinking water are (to be) exposed to arsenic concentrations of 30-40 µg/L until the planned treatment plant is in place. A probablistic risk assessment was conducted to estimate the human health risks for the scenario of no available surface water, in which no treatment and treatment with 90% and 99% efficiencies were assumed for the arsenic contaminated groundwater, based on the concentrations measured by the local health authority. The median carcinogenic risk estimated for the scenario of no treatment for the metropolitan area was approximately eight times the median value estimated when the main source water was Tahtalı Reservoir, a surface water dam. © 2008 Nova Science Publishers, Inc.

Energetic and Exergetic Design Evaluations of a Building Block Based on a Hybrid Solar Envelope Method
(Springer Verlag, 2018) Mert, Yelda; 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.

(Taylor & Francis, 2014) Hepbaşlı, Arif; Hancıoğlu Kuzgunkaya, Ebru; 01. Izmir Institute of Technology
The demand for energy has recently increased rapidly as a result of the world’s population increase and industrial growth. On the contrary, fossil fuel supply is declining due to depletion of the resources. Moreover, utilization of fossil fuel energy resources has resulted in adverse effects on the global environment. In this regard, there is an urgent need to implement the use of sustainable and environmentally clean energy sources. In this context, renewable energy sources, including geothermal sources, can play a critical role in meeting the energy demands of societies.

Experimental Evaluation of Actuation and Sensing Capabilities of a Haptic Device
(Springer, 2019) Mobedi, Emir; Görgülü, İbrahimcan; Dede, Mehmet İsmet Can; 03.10. Department of Mechanical Engineering; 03. Faculty of Engineering; 01. Izmir Institute of Technology
Haptic devices are used to increase the telepresence level by providing the sense of touch to the human operator. Simultaneously, they capture the targeted motion of the human operator to generate a motion demand for the teleoperated slave system. Considering a scenario where the slave system’s end-effector is handled by the human operator at the master side, which is attached to the haptic device, an ideal haptic interaction involves the feeling of only the end-effector dynamics and the accurate sensation of the end-effector pose. The performance of a haptic device is based on these two functionalities. In this paper, the experimental evaluation of the actuation and sensing capabilities of a haptic device, HIPHAD v1.0 kinesthetic haptic device, is presented.

Freestanding Silicene
(Springer Verlag, 2017-11) Cahangirov, Seymur; Şahin, Hasan; Le Lay, Guy; Rubio, Angel; 04.04. Department of Photonics; 04. Faculty of Science; 01. Izmir Institute of Technology
Obtaining a freestanding 2D graphene flake is relatively easy because it has a naturally occurring 3D layered parent material, graphite, made up of graphene layers weakly bound to each other by van der Waals interaction. In fact, graphite is energetically more favorable than diamond (which is one of the most stable and hard materials on Earth) that is the sp3 hybridized allotrope of carbon. To prepare freestanding graphene, it is enough to come up with a smart procedure for isolating the weakly bound layers of graphite. The same is also true for other layered materials like hexagonal boron nitride, black phosphorus, metal dichalcogenides and oxides. Silicene, on the other hand, doesn’t have a naturally occurring 3D parent material since silicon atoms prefer sp3 hybridization over sp2 hybridization. This makes the synthesis of freestanding silicene very hard, if not impossible. However, it is possible to epitaxially grow silicene on metal substrates and make use of its intrinsic properties by transferring it to an insulating substrate (Tao et al. 2015). In this chapter, we focus on intrinsic properties of freestanding silicene in the absence of the metallic substrate.

Function Generation Synthesis With a 2-Dof Overconstrained Double-Spherical 7r Mechanism Using the Method of Decomposition and Least Squares Approximation
(Springer, 2014-08-27) Kiper, Gökhan; Bağdadioğlu, Barış; 03.10. Department of Mechanical Engineering; 03. Faculty of Engineering; 01. Izmir Institute of Technology
This study addresses the approximate function generation synthesis with an overconstrained two degrees-of-freedom double spherical 7R mechanism using least squares approximation with equal spacing of the design points on the input domain. The 7R mechanism is a constructed by combining a spherical 5R mechanism with a spherical 4R mechanism with distant centers and a common moving link and then removing the common link. This construction allows the analysis and synthesis of the re-sulting single-loop mechanism by decomposing it into fictitious 5R and 4R loops. The two inputs to the mechanism are provided in the 5R loop and the output is in the 4R loop. The fictitious output of the 5R loop is an input to the 4R loop this intermediate variable is used to also decompose the function to be generated. This decomposition provides the designer extra freedom in synthesis and enables de-creasing the error of approximation. A case study is presented at the end of the study where the 7R de-sign is compared with an equivalent spherical 5R mechanism; hence the advantage of the 7R mecha-nism is demonstrated.
