INVESTIGATION OF VARIATION OF TRIAXIALTY AND LODE ANGLE PARAMETER VALUES IN SHEET METAL FORMING PROCESSES
Güzelderen, Tolunay; Darendeliler, Haluk; Department of Mechanical Engineering (2022-8-29)
The aim of this study is to find out the relations of stress triaxiality and Lode angle parameter with the deformation characteristics of deep drawing process. For this purpose, deep drawing process is analyzed numerically by using different yield criteria, ductile criteria and hardening models for two different sheet materials. The simulations are carried out by using the finite element method. Square and cylindrical cups made of Al-2024 aluminum and AISI 304 steel are formed. Von Mises and Hill48 yield cr...
AN INTERFERENCE AND BEAM SQUINT AWARE HYBRID MASSIVE MIMO FOR SPATIAL WIDEBAND BDMA CHANNELS
Özen, Hakan; Güvensen, Gökhan Muzaffer; Department of Electrical and Electronics Engineering (2022-2-10)
This study investigates interference and beam squint aware analog beamformer design for massive multiple-input multiple-output (MIMO) systems for spatial wideband beam division multiple access (BDMA) channels. Single carrier frequency domain equalization (SC-FDE) is employed in uplink frequency selective channels. We first design interference and beam squint aware (BSA) narrowband generalized eigenbeamformer (BSA NB GEB) based on a phase shifter (PS) network using slowly varying long-term channel statistics...

A Parameter Error Identification Method for Power Plant Dynamic Models
Açılan, Etki; Göl, Murat; Department of Electrical and Electronics Engineering (2022-6-30)
Incorrect parameters in a power plant dynamic model affect the analysis results and control decisions in a power system, which may have serious consequences. The online calibration techniques in the literature utilize sensitivity analysis to determine the identifiable parameters before the calibration, and treat majority of sensitive parameters as potentially erroneous. Hence, the candidate parameter subset for calibration mostly consists of distractors, i.e. highly sensitive but already correct parameters....
THE EXTENT AND LIMITATIONS OF MANAGERIAL ACCOUNTING FUNCTION WITHIN ERP SYSTEMS
Harman, Mustafa; Bakal, İsmail Serdar; Duran, Serhan; Department of Industrial Engineering (2022-2-11)
This thesis aims to investigate the extent and limitations of managerial accounting concepts within ERP systems for medium to big-sized companies, whose transactions and data generation are huge and require integrated, online, and real-time processing on a common database. The main purpose for managerial accounting within standard ERP systems is to automate costing, budgeting, and cost accounting by integrating with functional modules. This is not complete automation. The extent and limitations of this aut...
