Influence of time-dependency on elastic rock properties under constant load and its effect on tunnel stability

Aksoy, Cemalettin Okay; Uyar Aksoy, Guzin Gulsev; Güney, Avni; Ozacar, Vehbi; Yaman, H. E. (Techno-Press, 2020)

In structures excavated in rock mass, load progressively increases to a level and remains constant during the construction. Rocks display different elastic properties such as E-i and v under different loading conditions ...

Influence of two-step austempering at different temperatures on mechanical and microstructural properties of AISI 9254 high silicon steel

Nalcacı, Burak; Baysun, Meltem; Bahador, Abdollah; Umeda, Junko; Münstermann, Sebastian; Kaya, Ali Arslan; Erdoğan, Mehmet (Taylor and Francis Ltd., 2023)

This study was undertaken to understand the effects of two-step austempering treatment on an AISI 9254 high silicon steel towards tailoring the properties as desired while simultaneously employing the benefits of high and ...

Infrared thermography for civil structural assessment: demonstrations with laboratory and field studies

Hiasa, Shuhei; Birgül, Recep; Çatbaş, F. Necati (Springer Heidelberg, 2016)

A detailed investigation of infrared thermography (IRT) for civil structures is presented by considering different technologies, data analysis methods and experimental conditions in the laboratory and also in the field. ...

Input shaper design for minimum over travel

Gürleyük, Sırrı Sunay (2013)

Input shaping control reduces overshoot and settling time in oscillatory dynamical systems. Although its vibration eliminating ability is very successful, the controlled output cannot response quickly to a stop-now command. ...

The integrity loss of physicomechanical properties of building stones when subjected to recurrent cycles of freeze-thaw (F-T) process

Altındağ, Raşit; Şengün, Nazmi; Güney, Avni; Mutlutürk, Mahmut; Karagüzel, Remzi; Onargan, Turgay (Springer, 2006)

In this study, a total of nearly 900 samples were obtained from 7 different rock types, also recognised as marbles of sedimentary and metamorphic origin and commercially used in the building of various monuments, art works ...

AN INTELLIGENT POSTOPERATIVE CHRONIC PAIN PREDICTION SYSTEM (I-POCPP)

Kartal, Elif; Koçoğlu Önay, Fatma; Özen, Zeki; Emre, İlkim Ecem; Güngör, Gürcan; Sutaş Bozkurt, Pervin (ISTANBUL UNIV, 2022)

Objective: Postoperative Chronic Pain (POCP) affects the quality of patients' lives. Machine learning and its applications provide significant contributions to pain research. The aim of this study is to predict the POCP ...

An interactive multi-criteria decision-making framework between a renewable power plant planner and the independent system operator

Soltaniyan, Salman; Salehizadeh, Mohammad Reza; Taşcıkaraoğlu, Akın; Erdinç, Ozan; Catalão, João P.S. (Elsevier Ltd, 2021)

Providing efficient support mechanisms for renewable energy promotion has drawn much attention from researchers in the recent years. The connection of a new renewable power plant to the transmission system has impacts on ...

Investigation into Ca-Doped LaMnCoO3 Perovskite Oxides for Thermochemical Water Splitting

Yiğiter, İhsan Emre; Pişkin, Berke (Springer, 2022)

Two-step thermochemical water splitting (II-TWS), involving concentrating sunlight, has become prominent for green hydrogen production that does not require H2/O2 separation steps at high temperatures. The kinetics and ...

Investigation of chromite preconcentration by comminution

Polat, Ercan; Güler, Taki; Mohammed, M.M.A. (Baski, 2019)

Chromite is the main source of chromium. It is widely used in metallurgical, refractory and chemical engineering applications. Chromite occurs in earth crust generally with serpentine minerals as associated gangue. Serpentine ...

Investigation of design parameters of a failed soil slope by back analysis

Öge, İbrahim Ferid (Pergamon-Elsevier Science Ltd, 2017)

A soil slope instability occurred at the surface facility area of a mine site, which was successfully managed from occupational health and safety point of view, and no human or material loss was encountered. Three different ...
