The design of a compound mobile serial robot controlled remotely by a C# program utilizing the MQTT (Message Queuing Telemetry Transport) protocol is the main topic of this thesis. The robot is powered by a Raspberry Pi. The advantages of mobility and serial manipulators are combined in the compound mobile serial robot, allowing it to carry out difficult tasks in a variety of settings. As the main computer, the Raspberry Pi gives the robot and its control application connectivity and processing capability. Data interchange and command execution are made possible by the integration of the MQTT ...Daha fazlası
Because of the drawbacks related with the current corneal transplantation techniques such as donor shortage, rejection or disease transmission risk, there is still an urgent requirement in order to produce new treatments for regenerating corneal tissue. Specially, it is also necessary to overcome the problems related with the blindness and vision losses originating from damage to corneal endothelium. By considering these, corneal tissue engineering might possess an encouraging potential to ensure alternative and innovative approaches toward the development of effective corneal tissue equivalen ...Daha fazlası
3D realistic models are used in many fields such as engineering, archaeology, and city planning. The most effective technique used to create these models is the photogrammetry technique. The hardware and software features of the unmanned aerial vehicles to be used to implement this technique are of great importance. Many different unmanned aerial vehicles can be used for photogrammetric studies in the surveying and mapping industry, and therefore users have difficulties choosing needed unmanned aerial vehicles for their studies. In this study, 3D modelling performance and usage areas of popula ...Daha fazlası
Al-Si döküm alaşımlarında bir güçlendirme mekanizması olarak uygulanan tane
inceltme işlemi, ağırlıklı olarak otomotiv endüstrisinde kullanılan A356 alaşımı söz
konusu olduğunda kritik bir öneme sahiptir. Ti-B içeren tane incelticilerin
kullanımının neden olduğu solma ve zehirlenme etkilerinin ardından, araştırmacılar
yeni bir tane inceltici bileşimi arayışına girmişlerdir. Son yıllarda detaylı olarak
çalışılan Nb-B içeren tane inceltici ana alaşımın olumlu etkilerinin görülmesi ancak bu
etkilerin kayda değer bir sonuç üretmemesi üzerine Nb-Ti-B üçlü bileşimi üzerinde
çalışmalar yapılmı ...Daha fazlası
Kolorimetrik analiz, biyomoleküllerin saptanmasında kullanılan ve çıplak gözle
gözlemlenen maddenin varlığını ve konsantrasyonunu belirlemek için renk
değişimlerini kullanılarak ölçülmesini sağlayan bir tekniktir. Sağlık, gıda, ilaç,
kozmetik ve boya endüstrileri gibi birçok farklı alanda biyolojik, tıbbi ve çevresel
numunelerin analizinde kolorimetrik analiz kullanılmaktadır. Bakım-noktası (POC)
testleri kullanım kolaylığı ve ulaşılabilirliği nedeniyle bir çok alanda kullanılmaktadır.
POC testlerinin kolorimetrik analiz ile entegrasyonu kullanım kolaylığını
arttırmaktadır. Kolorimetrik ...Daha fazlası
Polymers contain moisture due to their chemical structure. Moisture in polymers is important for the quality of the final product and ease of processing. For this reason, polymers are subjected to drying before processes such as injection and extrusion. Drying is carried out at temperatures and times specified by the polymer suppliers. Over-drying leads to increased viscosity (processing difficulty) while under-drying leads to flow marks, burrs, and reduced tensile strength and impact strength. Over-drying also causes excessive energy consumption. In this study, the drying process optimization ...Daha fazlası
The aim of this thesis was to develop a wearable tele-physiotherapy device that addresses the remote elbow joint rehabilitation. The developed device consists of a wearable exoskeleton equipped with servo motor, joint angle sensor, EMG sensor, battery and Wi-Fi module. By connecting with the Android mobile application, it enables real-time monitoring of EMG data and programming of personalized exercise programs. The device offers convenience and comfort to patients by eliminating the need for face-to-face physiotherapy sessions and aims to reduce treatment costs and treatment time.

Duplex steels are materials that contain ferrite and austenite phases in their structure, have high resistance to corrosion, and also show improved mechanical values. While the austenite in its structure provides general corrosion resistance and ductility, ferrite provides resistance to stress corrosion cracking and mechanical strength. Duplex steels have widespread use, especially in shipping and petrochemistry. The current production method of duplex steels, which are in demand with a wide usage area, is generally argon oxygen decarburization furnaces (AOD). In addition to the production met ...Daha fazlası
The recent increase in life expectancy and changing living conditions have led to a
rise in developments regarding implants, particularly in orthopedic implants. It is
important to note that this statement is based on objective evidence and not
subjective evaluations. Despite these advances, issues with metallic implants such as
Ti, Ti alloy, Co-Cr alloy, and stainless steel (AISI 316L), which are currently
preferred, persist. There are several limitations to implant materials, including
corrosion due to the physiological environment, bacterial infection, and biofilm
formation. Although ...Daha fazlası
