In this proposal, microcontroller-based energy flow control was designed in order to effectively and efficiently enable the use of energy sources in a hybrid energy generation system including wind, solar, and hydrogen energy. It was assumed that the hybrid energy generation system is dynamic during the design of the microcontroller-based energy flow control. A wind-solar energy generation system was determined as the base load power plant. Depending on the demand, the battery group and fuel cell were activated effectively. If an energy surplus occurred, it was stored in battery groups and transformed into hydrogen energy via a hydrogen generator simultaneously. In addition to providing energy sustainability, a constant active status of the energy storage group was prevented and the physical life of the group was prolonged by means of the microcontroller-based control system. If consumer demand could not be met by the main energy sources including wind and solar energy, the battery groups and fuel cell were activated and provided the energy sustainability. After a certain level of charge was reached in the battery group, it was deactivated via the control system in order to prevent unnecessary use of energy. By means of the microcontroller-based control system, the usage of energy generated with the hybrid energy generation system was analysed according to its efficiency.

Ni-Fe metal matrix composites reinforced with WC have been fabricated by microwave sintering at various temperatures. A uniform nickel layer on WC and Fe powders was deposited prior to sintering using electroless plating technique, allowing closer surface contact than conventional methods such as mechanical alloying. The reactivity between WC and Fe powders to form carbides of Fe is controlled through Ni layer existing on the starting powders. A composite consisting of quaternary additions, WC, Ni and Fe was prepared at the temperature range 500°C-900°C under Ar shroud. X-Ray Diffraction, SEM (Scanning Electron Microscope), compression testing and hardness measurements were employed to characterize the properties of the specimens. Experimental results carried out for 900°C suggest that the best properties for omax and hardness (HV) were obtained at 900°C and the microwave sintering of electroless Ni plated WC and Fe powders is a promising technique to produce ceramic reinforced composites.

The scope of this study, that is, the effect of the elastic modulus obtained by ultrasonic method on the physical and mechanical properties of tungsten carbide (WC)-based ceramic–metal composites, which have Ni and Co metallic binder composition produced by powder metallurgy and represented by high strength and hardness criteria, was investigated. In order to obtain composite samples in the study, it was sintered in a microwave furnace at different temperatures to combine the powder particles prepared at the rate of 60% Ni, 20% Co, and 20% WC by weight. Then, the velocities and longitudinal attenuation values of longitudinal and shear ultrasonic waves along the composite sample were measured using the ultrasonic pulse-echo method. The elastic modulus of the composites was determined using ultrasonic velocities and sample density. Hardness testing, scanning electron microscopy (SEM), and X-ray diffraction (XRD) analyses were also performed. The results show that the elastic modulus increases with the increase in sintering temperature and ultrasonic wave speeds, but decreases with the longitudinal attenuation value, considering the SEM images and XRD analysis. There is also a linear relationship between elastic modulus and stiffness.

Göğüs kanseri dünya genelinde kadınlarda en çok karşılaşılan kanser türüdür. Günümüzde her kadının başına gelebilecek olan göğüs kanseri, erkeklerde de görülebilmektedir. Göğüs kanserinde insanların fiziksel ve zihinsel halleri çok etkilidir. Göğüs kanserine karşın tedbirli olabilmek için belirli aralıklarla göğüs dokularının incelenmesi gerekmektedir. Bu dokular, uzmanlar tarafından incelenmektedir. Ancak inceleme esnasında yapılan yanlış teşhisler tedavi sürecini olumsuz etkilemektedir. Bu sebeple, bu dokuların sayısal ortamda işlenip incelenmesi daha faydalı olmaktadır. Bu çalışmada, YSA ile göğüs kanserinin sınıflandırması yapılmıştır. Mamografi görüntüleri üzerinde Döndürülmüş Yerel İkili Örüntü (RLBP) metodu kullanılarak öznitelikler çıkarılmıştır. Bu öznitelikler, parametreleri belirlenmiş olan YSA aracılığı ile eğitilmiştir. Eğitim sonucunda iyi ve kötü huylu olarak sınıflandırılan ikili sınıflandırmada %87,82 ve Yağlı, Yağlı-Glandüler ve Yoğun-Glandüler olarak sınıflandırılan üçlü arka plan doku sınıflandırmasında %80,95 başarı oranı elde edilmiştir.

In this study, SiC reinforced nickel matrix composites, microwave at different temperatures It is produced by sintering in oven. Nickel deposition on SiC powders was achieved by using electroless nickel plating technique. It is sintered at temperatures between 500°C, 600 °C, 700°C, 800°C and 900°C under Ar atmosphere. XRD, SEM (Scanning Electron Microscope), pressure test and hardness measurements were used to characterize the properties of sintered samples in microwave furnace. The experimental results, maximum compressive strength (σmax) and hardness (HV) were carried out at 800 °C. Microwave sintering of Ni-coated SiC powders without electric current can be a promising technique for producing ceramic-reinforced nickel composites.

Titanium based intermetallic compounds are frequently used in the production of biomaterials. The behavior of titanium similar to bone mechanical properties causes the use of titanium as a biomaterial and preferred among the materials. It also makes its use attractive in industrial applications at high temperatures. TiCrCo intermetallics are known to be used together with Ti matrix materials to improve the properties of the group in addition to elements such as Cr, especially Ti, Co, Mo and Fe in various application areas. This information is used frequently in the sintering process. In this study, Ti-10Cr-3,33Co-3,33 egg shelter powders were prepared as a sample mixture. When the properties of the samples produced after sintering are examined, it shows the effects of Co on TiCr. 3.33% Co additive was used in the composition of the composition and mechanical properties were determined in the produced samples. By looking at metallographic analysis, structural features were tried to be determined. The density of the produced samples was calculated, hardness and shear strength were determined.
