Design and usage of Unmanned Aerial Vehicles (UAV) especially for military purposes has been rapidly increasing in recent years due to their capability to endure long flight durations without needing a crew and due to their low cost compared with the conventio…
Energy dissipaters used in open channels are devices designed to reduce the flow velocity and allow water to pass downstream without harming water structures and environment. In this study the effect of energy dissipaters on energy loss is investigated depende…
This study presents a Hybrid Digital-Physical Risk Management Framework designed to enhance urban climate resilience through the integration of Industry 4.0 technologies. By combining real-time IoT sensor networks, AI-based predictive analytics, and blockchain…
Hareket sırasında dairesel alanları tarayan sistemlerde, hareket hızını ölçmek için yaygın olarak jiroskoplar, takometreler ve kodlayıcılar kullanılır. Bu çalışmada, manyetometre, jiroskop ve ivmeölçer içeren BNO055 sensörü açısal hareketi ölçmek için kullanıl…
This study aims to investigate the effect of pitching motion of a NACA 0012 airfoil on the lift and drag coefficients at different reduced frequencies for a flow over the airfoil at Reynolds number of 5x105. A two-dimensional computational analysis was perform…
This paper introduces the International Terrestrial Reference Frame (ITRF) transformation software for stations’ three-dimensional coordinates and velocities. The software allow to 14-parameter transformation. The software is written in MATLAB programming lang…
The industrial–style designs affecting today’s perception of designs in a huge velocity has emerged first by the industrial revolution. Although being time–dependent and taking longer time and economically highcost product, the handcraft has allowed the indus…
Renewable energy can be produced by using kinetic energy of the flowing water such as rivers, ocean currents and tidal flows. The kinetic energy can be transformed to the power by hydrokinetic turbines. There are many different designs of hydrokinetic turbin…
In this study, mixed convection heat transfer and fluid flow in a three-dimensional horizontal duct with three different geometries of cavity were investigated numerically. Air flows in a square duct which is heated by a cavity with triangular, a rectangular a…
Exhaust gas distribution in street canyons is one of the important research subjects in urban air quality studies. Vehicle emissions are an important group of pollutants in urban areas. In this study, the dispersion of exhaust emissions from vehicles in canyon…
Ortodontik tedavi sırasında diş hareketini etkileyen önemli faktörlerden biri sürtünme kuvvetidir. Sürtünme kuvvetine etki eden faktörlere müdahale edilebilirse ortodontik tedavinin süresi ve başarısı ile ilgili olumlu tahminler yapmak mümkün olacaktır. Sürtün…
