A useful and flexible method based on the salp swarm algorithm (SSA) for the pattern nulling of linear antenna arrays with the prescribed nulls is presented. SSA is a relatively new population based evolutionary optimization algorithm. Nulling of the pattern i…

Maxwell denkleminin AV formülasyonu esas alınarak, zamana bağlı bir akım altında süperiletken telin elektromanyetik özelliklerini çözmek için yeni bir sayısal model geliştirilmiştir. Farklı akım genlikleri için alternatif akım (AA) kayıpları hesaplanmış ve iki…

Bilişsel radyo kullanılmayan ya da az kullanılan spektrum bantlarına dinamik olarak erişim olanağı sağlayan ve kullanıcılar arasında herhangi bir olumsuzluğa neden olmadan spektrum paylaşımını gerçekleştiren yazılım tabanlı bir teknolojidir. Kablosuz haberleşm…

In the world, constructions are mostly reinforced concrete framed structures with infill walls. Different reinforcement studies have been carried out on these existing structures in order to ensure the safety of life and property without heavy damage because o…

Görüntüde yer alan nesnelerin kenarlarının belirlenmesi, görüntü işleme alanında önemli bir yer tutmaktadır. Piksellerin, komşu oldukları piksellere benzerlikleri de kenar belirleme amacıyla kullanılmaktadır. Ancak elde edilen benzerlik değerlerine göre kenar …

Nowadays, there are old and new methods that involve the difficult problems and solution suggestions which many researchers research and try to solve. In the field of engineering, the success rates of the methods that produce solutions to these problems are of…

In this work, Intralube E with 0.38 % C press-ready mix powders were pressed with 550 MPa pressure and sintered 25 min at 1120 °C. Samples were coated electrochemically with nano diamond (ND) reinforced nickel to study the effect of nano composite coating on c…

3D printing filling structures at prototyping and design stage are increasingly important issue for products with complicated shapes. The objective of the present study is to investigate 3D printing filling structures effect on mechanical properties and surfac…

Aluminum based metal matrix composites are frequently used in automotive, aircraft, space, automotive, agricultural and building industries due to their easy shaping, good heat and electrical conductivity, low density, high strength and toughness. In these com…

In this study, 0-12wt.% of Si3N4 or 0-30wt.% of SiC was added to the aluminum matrix by powder metallurgy method. Hence, the effect of reinforcement elements’s (SiC or Si3N4) amount on the mechanical properties was examined. Micro structures and crystal struct…

Climate change effects have been remarkably today; the determination of trends in temperatures, precipitation, stream flow, winds and evaporation has become considerable for the planning and management of water resources and engineering projects. Nowadays ther…

The aim of this study is to determine instantaneous irradiance and annual percentile sunlit time on the available rooftop floor area of Technical and Social Science Vocational School at Usak University by simulation using open source software. The building of …

Stress corrosion is a dangerous type of corrosion occuring as a result of effective with corrosive environment and stress of sensitive a material. Many metallic material may be exposed to stress corrosion damage depending on operating conditions. In order to d…

This paper describes a laboratory application for the forecasting the dielectric properties, using an artificial neural network embedded in a microprocessor. The dielectric permittivity and loss factor of the insulation material were determined as a function o…

Aim of the study: It is important to be able to plan the production transmission and distribution necessary for uninterrupted electricity and to use the electricity more efficiently and to make demand forecasts. For this reason, it is aimed to estimate the ele…

The column materials in the form of monodisperse and porous particles were synthesized with regard to test their column performances in Ion Exchange Chromatography (IEC) mode. Particles in the form of poly(glycidil methacrylate-coethyleneglycol dimethacrylate)…

In the United States, banking desert status is classified annually from that same year’s branch data, producing a contemporaneous snapshot of current access rather than a forecast of which communities are likely to change status next. This study tests whether …

This paper explores how intra-day volatility behaves across different weekdays during periods of major financial stress, focusing specifically on the S&P 500 and NASDAQ-100 indices. The analysis spans two significant market disruptions—the 2008 Global Financia…

This study presents a comparative analysis of post-earthquake recovery governance in Türkiye and Japan, focusing on the 1999 Kocaeli, 2011 Tōhoku, and 2023 Kahramanmaraş earthquakes. Employing qualitative document analysis and cross-case timeline mapping, it e…

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…
