Control and design of industrial robotic arm by using ROS ROS kullanarak endüstriyel robotik kolun kontrolü ve tasarımı

Candemir, Adem

ABSTRACTIndustrial robots currently used in industry all have their own interfaces and unique languages. These commonly used interfaces and languages are often limited to industry needs. Although there are several robotic solutions, practically all of them can't rectify problems on their own. When a program is required for a more complex task, machine vision locates objects and puts them in desired locations and for situations such as applying the correct force for assembly operations by measuring with force-torque sensors, they often need third-party programs as existing systems cannot respon ...Daha fazlası

Oxygen level and particle size effects on sintering of binder jetting copper parts Bağlayıcı püskürtmeli eklemeli imalat yönteminde bakır parçaların sinterlenmesinde tane boyutunun ve oksijen seviyesinin etkisi

Özateş, Cem

ABSTRACTCopper is one of the most conductive metallic materials. For most metals, additive manufacturing is prone to laser or electron beam powder bed fusion processes. Due to copper's high reflectivity and very high thermal conductivity, it is difficult to print 3D parts with powder bed fusion methods. Binder jetting, which is a developing 3D printing technology, has a high potential for use in order to eliminate these problems of copper and low processing costs. In this study, the effect of particle size distributionand oxygen level of the copper powders on part density, tensile strength, su ...Daha fazlası

Utar, Bahar

ABSTRACTBone healing is one of the important issues in clinical areas such as oral, maxillofacial, orthopedic, and plastic surgery. Especially in the implantation process to be performed in dental applications, the structure of the jawbone and the quality of the bone density are very important for the performance of the process. In the area of tissue engineering, there are biodegradable bone implants with biocompatible synthetic polymers that give successful results in many areas. The dental barrier membrane is a synthetic bone graft based on Poly (DL-lactide). It is used in many dental applic ...Daha fazlası

A vehicle routing problem based scenario analysis for optimum siting of municipal solid waste transfer stations Belediye katı atık aktarma istasyonlarının optimum yerleşimi için araç rotalama problemine dayalı senaryo analizi

Höke, Milas Ceren

ABSTRACTThe management of public services requires an in-depth decision-making method to provide the intended functionality and service life. Municipal solid waste management is indeed one of the most challenging tasks of local municipalities and currently occupies a substantial portion of the overall municipal expenses. In this study, an entirely geographic information system (GIS) based facility siting method is developed to aid governmental bodies in the decision-making process to site such facilities. The proposed method is applied to site a transfer station (TS) in the southeastern region ...Daha fazlası

Analyzing gastronomy influencers' views about gastronomy tourism Gastronomi odakli sosyal medya kanaat önderlerinin gastronomi turizmi hakkında görüşlerinin incelenmesi

Ertamay, Selin

ABSTRACTAlthough gastronomy has always been a significant component of tourism products and tourist experience, with the changing tourist motivations and tourism trends gastronomy tourism has developed as a major type of alternative tourism all around the world since the 90s. Today, gastronomic values of the destinations attract many tourists and governments pay importance to gastronomy tourism as a tool in increasing for their tourism incomes. Social media is a digital platform that make individuals able to digitally interact with each other based on their interests. It has modified the way o ...Daha fazlası

Investigation of the adhesive-bonded aluminum-polyamide hybrid joints Yapıştırıcı ile birleştirilmiş alüminyum-poliamid hibrit bağlantıların incelenmesi

Batıkan Kandemir, Miray

ABSTRACTToday, environmentally friendly, high-strength and lightweight engineering materials are becoming increasingly important for the automotive and aviation industries. For this purpose, it is critical to combine different materials correctly and to create a reliable hybrid structure. Adhesives have a huge market share among the joining methods due to their low-stress concentration, high formulation possibility, good fatigue resistance, and sealing advantages. However, surface properties and surface treatments play an active role in determining joint performance. In this thesis, the effect ...Daha fazlası

A comparison of the performances of conventional and low salinity water alternating gas injection for displacement of oil Petrolün geleneksel su gaz değişimli ötelenmesi ile az tuzlu su gaz değişimli ötelenmesi yöntemlerinin başarımlarının karşılaştırılması

Bucyanayandi, Emmanuel

ABSTRACTThe oil and natural gas reside in microscopic pores of subsurface rock layers called a reservoir rock. Besides there always at least two phases exist in oil and gas reservoirs. Therefore, the flow and displacement of oil into the production wells are influenced significantly by capillary forces. Due to the capillary and surface forces, the recovery of oil always remains at low percentages usually between 20 to 40. In order to increase the recovery factor several secondary and enhanced oil recovery techniques have been developed and implemented. The two secondary recovery methods namely ...Daha fazlası
