An Approximate MSE Expression for Maximum Likelihood and Other Implicitly Defined Estimators of Non-Random Parameters
Mehmetcik, Erdal; Orguner, Umut; Candan, Çağatay (2023-03-01)
An approximate mean square error (MSE) expression for the performance analysis of implicitly defined estimators of non-random parameters is proposed. An implicitly defined estimator (IDE) declares the minimizer/maximizer o...
Cooperative Guidance Law for High-Speed and High-Maneuverability Air Targets
Cevher, Firat Yilmaz; Leblebicioğlu, Mehmet Kemal (2023-2-01)
In this paper, a novel cooperative and predictive guidance law is proposed to intercept high-speed and high-maneuverability targets with inferior interceptors. The purpose of guidance is cooperatively covering the most-pro...
Lane change scheduling for connected and autonomous vehicles
Atagoziev, Maksat; Güran Schmidt, Ece; Schmidt, Klaus Verner (2023-02-01)
The execution of lane changes has a strong impact on driving safety and traffic throughput. Therefore, it is highly desired to automate and coordinate lane changes. The subject of this paper is the scheduling of lane chang...
A Novel Parameter Error Identification Method for Power Plant Dynamic Models
Açılan, Etki; Göl, Murat (2023-01-01)
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 sens...
Spheroid Engineering in Microfluidic Devices
Tevlek, Atakan; Kecili, Seren; Ozcelik, Ozge S.; Külah, Haluk; Tekin, H. Cumhur (2023-01-01)
Two-dimensional (2D) cell culture techniques are commonly employed to investigate biophysical and biochemical cellular responses. However, these culture methods, having monolayer cells, lack cell-cell and cell-extracellula...
A Hierarchical Control of Supercapacitor and Microsources in Islanded DC Microgrids
Barati, Farhad; Ahmadi, Behzad; Keysan, Ozan (2023-1-01)
This paper proposes a hierarchical control approach for SuperCapacitor (SC) energy storage and microsources in islanded DC microgrids. It takes into account microsources' dynamic and steady-state limitations. The proposed ...
