Investigation of changes in the formation and types of non-metallic inclusions in the steel production process Çelik üretim sürecinde oluşan metal olmayan kalıntıların oluşumu ve değişimlerinin incelenmesi

Bakar, İbrahim

ABSTRACTIt is not possible to produce steel without inclusions as the process for steel production requires. Based on this fact, the researches on clean steel are concentrated on the reduction of inclusions and transformation of inclusions into harmless state by modification. The definition of steel cleanness is related to final product application. Non-metallic inclusion, in the liquid steel, causing many problems and production lost in steel production process and final application. Aluminum killed steels mostly contain Al2O3 and MnS inclusions. Al2O3 inclusions are formed during de-oxidatio ...Daha fazlası

Numerical investigation of inverse magnus effect on a circular cylinder by controlling azimuthal circulation distribution Ters magnus etkisinin çevresel sirkülasyon dağılımı kontrolü ile dairesel silindir üzerinde sayısal olarak incelenmesi

Çelik, Acar

ÖZETMagnus etkisi, belirli koşullarda ortaya çıkan fiziksel bir olgudur. Bu fenomeni gözlemlemek için, bir akış ortamına daldırılmış dönen bir gövdeye (genellikle küre veya silindir) sahip olmak gerekir. Geri çekilme tarafındaki akış (gövdenin akışla aynı yönde hareket eden tarafı) dönüş yönünde yön değiştirir ve ters yönde etki eden bir tepki kuvveti (diğer bir deyişle kaldırma kuvveti) oluşturur. Ters Magnus etkisinde ise kuvvet tam zıt yönde oluşmaktadır. Kritik Reynolds sayısı ve dönme oranı aralıklarında, geri çekilen taraftaki akış laminer olma eğilimindedir ve bu da erken akış ayrılması ...Daha fazlası

The Relationship of Adherence to the Mediterranean Diet, Dietary Inflammatory Index and Nutrient Intake in University Students: A Cross-Sectional Study

Objective: Investigating the relationships between dietary inflammatory index (DII), nutrient intake, and adherence to the Mediterranean diet (MD) of university students was aimed in the present study. Material and Method: A questionnaire consisting of socio-demographic characteristics, the Mediterranean Diet Adherence Screener (MEDAS), the 24-hour food record, and the DII scoring was completed by undergraduate students in Uskudar University. Results: A total of 750 students (52.3% male, mean age= 21.6±2.2 years, mean body mass index= 23.97±2.63 kg/m2) were included in the study. Half (50.7%) ...Daha fazlası

Online learning stable adaptive controller for chaos control of bldc motor Fırçasız motorun kaos kontrolü için çevrimiçi öğrenen kararlı adaptif kontrolör

Gökçen, Alkım

ABSTRACTThis thesis presents an online learning stable robust adaptive controller design for the chaos control of the brushless direct current (BLDC) motor. The proposed adaptive controller algorithm consists of a Wiener model-based controller with a nonlinear auto-regressive moving-average (NARMA) based artificial neural network (ANN), and a Hammerstein based plant model. The developed online learning closed-loop control system providing stability and robustness might be defined as an auto-regressive moving average (ARMA) based system identification problem with partially known parameters.

Investigation of Use of Lead Oxide Extracted from Recycled Batteries in Radar Absorbing Stealth Technology

Gürkan Ergün

Radar, uçakların tespiti ve takibi için en yaygın tekniktir. Radar, havacılık trafik yönetiminde vazgeçilmez bir araç olmasına rağmen, uçağın hedefini saldırıp fark edilmeden kaçmasını gerektiren saldırgan askeri operasyonlarda sorun oluşturur. Radar, elektromanyetik dalgaların atmosfere yayılmasını içerir; daha sonra uçaktan yansıyarak bir alıcı antene geri döner. Radar Emici Malzemeler (RAM), uçağın elektromanyetik dalga enerjisini emerek yansıyan sinyalin yoğunluğunu en aza indirmesi prensibiyle çalışır. Gizlilik ve görünmezlik gibi son derece önemli olan gizlilik teknolojisini sağlayan rad ...Daha fazlası
