Design and Development of a Compound Mobile Serial Robot with Remote Control Application

Alpay Toprak

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

Effect of Sediment Load on the Time Evolution of the Morphology of a Large-scale Laboratory Movable-bed Symmetrical Confluence

Zehra Büyüker

Akarsu kavşakları doğal drenaj ağlarının temel unsurları olup oluşturdukları habitat yüksek ekolojik değer arz etmektedir. Yan kollardaki sediment yükü ve akım arasındaki etkileşim kavşak morfolojisini düzenleyen önemli bir faktördür. Yan koldan gelen sediment yükü ve debinin ana kanal boyunca yer yer oyulmalara ve yığılmalara sebebiyet verdiği, bunların sonucunda da taban topoğrafyasında zamana bağlı değişimlerin olduğu gözlemlenmektedir. Bu çalışmada İzmir Kâtip Çelebi Üniversitesi Hidrolik Laboratuvarında bulunan, simetrik iki yan kolun 90˚ açı ile ana kanala bağlandığı açık kanal kavşağı ü ...Daha fazlası

Dynamics of Axisymmetric Drops Impacting onto Heterogeneous Surfaces

Atalay SEÇER

The way a droplet behaves when it lands on a surface depends on the characteristics of the surface and the flow conditions of the droplet. It can deposit, rebound, splash, etc. There is delimited research on how surface roughness and chemical composition affect the deformation of droplets upon impact, in comparison to the studies done on smooth surfaces. Our model uses two-phase flow to simulate the axisymmetric motion of droplets over surfaces with heterogeneities by combining the Navier-Stokes equations for motion with the Cahn-Hilliard equation for tracking the phase-field. We integrate the ...Daha fazlası

Determination and Modeling of Shear Strength Behavior of Soil – Geosynthetic Interface

İnci ERTAM

Bu çalışmada, farklı zeminler ve geomembranlar (GM) arasındaki arayüzleri etkileyen mühendislik parametreleri, kür sıvısı, kür süresi ve normal gerilme sınıfı gibi çeşitli koşullar altında incelenmiştir. Ayrıca depolama sahaları gibi birden çok geosentetiğin (GS) bir arada kullanıldığı tasarımlarda, GS’ler arasında oluşan arayüzeylerde de potansiyel kayma yüzeyleri oluşabilir. Bu nedenle, bu çalışmada aynı zamanda GM ve geotekstiller arasındaki arayüzeyler de araştırılmıştır. İlk aşamada, GS’lerin ve zeminlerin mühendislik parametreleri laboratuvar deneyleri ile belirlenmiştir. İkinci a ...Daha fazlası

Disasters and Migration: Kahramanmaras Earthquakes

On 6th February 2023, two consecutive earthquakes occurred in our country with a magnitude of 7.8 Mw in Kahramanmaras (Pazarcik) and 7.6 Mw in Kahramanmaras (Elbistan). Due to these earthquakes and aftershocks, 48,448 people have lost their lives in Türkiye. A bi-directional and very intense population movement from/to the earthquake area after these earthquakes was observed. Knowing the residence decisions of the disaster victims is important. In the face of the “disaster of the century”, “potential or actual” disaster victims or “pseudo disaster victims”, who exhibit the behavior of disaster ...Daha fazlası

Artificial Intelligence Based Resource Allocation in Cell-Free Networks

Mert Demirel

With the rapid development of technology, cellular networks can no longer meet the demands of wireless networks. Communication systems need to be updated to ensure that every user equipment (UE) receives accurate and efficient service. Cell-free (CF) networks offer advantages over cellular networks, such as more flexible resource allocation, higher capacity, better coverage and lower interference. The deployment of multiple access points (APs) and flexible allocation of resources leads to higher network performance and efficiency. In addition, in CF networks, users can communicate with ...Daha fazlası
