Design of a solenoid based prototype injector for evaluation of electromagnetic parameters
Yağcı, Ayhan; Quresh, Muhammad Sarmad; Kuntuz, Mehmet Polat; Bebek, Özkan (IEEE, 2019)Injector is a pump and valve mechanism, that sprays liquid intermittently to intended volume. In this research, evaluation of the electromagnetic properties of a solenoid actuator used in the prototype injector systems has ... -
Development of an antagonistically actuated smart joint
Vahidyeganeh, Ali; Şimsek, Görkem Muttalip; Jabeen, Saher; Bebek, Özkan; Yapıcı, Güney Güven (Trans Tech Publications, 2017)Shape memory alloys with their phase transformation properties; have been broadly implemented in smart structures. In this study, a functional design is presented where two wires actuate antagonistically to achieve motion ... -
Discrete-time integral sliding mode control of a smart joint for minimally invasive surgeries
Jabeen, Saher; Yeganeh, Ali Vahid; Şimsek, Görkem Muttalip; Yapıcı, Güney Güven; Abidi, K.; Bebek, Özkan (IEEE, 2016)In this work, a shape memory alloy(SMA) actuator based joint (smart joint) is controlled using a discrete-time integral sliding mode (DISM) control to guide the motion of an active catheter. Controller is designed on the ... -
Evaluating the mechanical behavior of ARB processed aluminum composites using shear punch testing
Aljashaami, Dhyai Hassan Jawad; Ghobadlou, Ali Hosseinzadeh; Mısırlı, Mustafa; Yapıcı, Güney Güven (Trans Tech Publications Ltd, 2020)Multi-layered metal composites have received considerable attention due to their improved mechanical and physical properties. In this study, Al6061/Al2024 composite was processed by accumulative roll bonding (ARB) as a ... -
An experimental investigation into frost accumulation over vertical finned and unfinned surfaces during impinging air flow
Öksüz, Enes Abdülhakim; Saygın, Alper; Başol, Altuğ Melik; Budaklı, M.; Arık, Mehmet (ASME, 2020)Frost formation on evaporators negatively affects the cooling performance of refrigerators. It increases the thermal resistance between the refrigerant and air leading to a reduction in the system cooling capacity. In this ... -
High power series elastic actuator development for torque-controlled exoskeletons
Yıldırım, Mehmet Can; Kansızoğlu, Ahmet Talha; Şendur, Polat; Uğurlu, Regaip Barkan (Springer Nature, 2019)This paper presents the development procedures of a high power series elastic actuator that can be used in torque-controlled exoskeleton applications as a high-fidelity torque source. In order to provide a high torque ... -
Impact of junction temperature over forward voltage drop for red, blue and green high power light emitting diode chips
Muslu, Ahmet Mete; Özlük, Burak; Tamdoğan, Enes; Arık, Mehmet (IEEE, 2017)Commercially available light emitting diodes (LEDs) that have high efficiencies and long lifetime are offered in advanced packaging technologies. Many cooling systems were developed for current LED systems that enable a ... -
Integrated engineering and architecture for the energy efficient academic buildings
Mengüç, Mustafa Pınar; Somuncu, Yasemin; Çağlayan, Şahin; Özcan, Saadet; Sefer, Burak; Simitli, Utku (International Building Performance Simulation Association, 2015-12)In this paper, we outline a comprehensive and integrated collaboration between engineering and architecture team to build an energy efficient building. Within the framework of the EU FP7 project, titled NEED4B, we have ... -
Segregated approach for the modeling of continuous heat treatment furnaces
Siddiqui, Faizan Pervez; Menekşedağ, Kaan; Başol, Altuğ Melik; Mengüç, Mustafa Pınar (Begell House Inc., 2019-06)Accurate modeling of the transient material temperature distribution inside the continuous heat treatment furnaces are very critical in terms of adjusting the process parameters of the furnace operations. In this study the ...
