A model for optimal operation of land-treatment sites for oily wastes
Ünlü, Kahraman (SAGE Publications, 2001-06-01)
Land treatment as a disposal technology has been extensively used for the disposal of oily wastes. Effective management of land treatment sites require optimal operation of the system in order to achieve the fastest and most complete degradation of petroleum hydrocarbons without contamination of the environment. This paper describes a model that can be used for optimising the operation of land treatment sites for oily wastes. The model is composed of system simulator and optimisation submodels. Conceptually...
A Methodology for Optimal Layout Design of Pressure Cells for Concrete Faced Rockfill Dams
Arı, Onur; Yanmaz, Ali Melih (Springer Science and Business Media LLC, 2018-08-01)
In this study, a methodology for optimal layout design of pressure cells for concrete faced rockfill dams is developed. A representative dimensionless stress distribution model was formed for obtaining the magnitudes and location of different stress zones as a function of dam height. This information enabled development of a procedure for proper location and the number of pressure cells throughout the dam body. A vertical placement algorithm based on error minimization was first developed, which is followed...
A methodology for reliability-based design of rock slopes
DUZGUN, HSB; Yücemen, Mehmet Semih; Karpuz, Celal (Springer Science and Business Media LLC, 2003-04-01)
A reliability-based methodology for the design of rock slopes, that can easily be implemented by the practicing engineers is proposed. The advanced first-order second-moment (AFOSM) method is adopted as the reliability assessment model and its application is illustrated for the case of plane failure. A model is developed within the framework of first-order second-moment approach to analyze the uncertainties underlying the in situ shear strength properties of rock discontinuities. Here, particular emphasis i...
A model for evaluating the potential of litigation due to contract ambiguity in international construction projects
Yenişehirlioğlu, Ahmethan; Sönmez, Rifat; Department of Civil Engineering (2022-8)
Disputes are unavoidable due to the unique interests of the parties and the challenging, complex and oppositional nature of the industry in the construction sector. For this reason, many researchers have conducted studies on disputes and dispute resolution in construction projects. Litigation, which is the last resort of disputes, is an unwelcomed process for all parties causing loss of time, money and reputation. In this respect, both the owner and the contractor require to prevent the factors that cause d...
A method and electrical model for the anodic bonding of SOI and glass wafers
Tatar, E.; Torunbalci, M.M.; Alper, S.E.; Akın, Tayfun (2012-02-02)
This paper provides a method for the anodic bonding of SOI and glass wafers, and it explains the bonding mechanism with an electrical model, for the first time in the literature. SOI-glass anodic bonding can be achieved at voltages as low as 250V similar to Si-glass anodic bonding, and the underlying principles can be understood by modeling the overall system with a series-connected capacitor-resistor network. The SOI-oxide layer can be added as a capacitor to the classical anodic bonding model, and the beh...
