Teknolojinin ilerlemesi ile birlikte birçok veri dijital ortamlarda kayıt altına alınarak büyük veri yığınları ortaya çıkmıştır. Veri madenciliği sayesinde bu büyük veri yığınlarının içinden anlamlı ve yararlı bilgilerin ortaya çıkarılması için çalışmalar yapı…
Güneşlenme süresi, çok sayıda uygulama için temel veridir. Esas olarak güneş enerjisi tahmininde kullanılmaktadır, ancak aynı zamanda özellikle iklim tabanlı uygulamalar için önemli bir veri kaynağıdır. Bu nedenle, güneşlenme süresinin mekansal ve zamansal d…
Erosion is among the leading factors threatening our sources of soil and water. The use of soil susceptibility indices to determine erosion and risk situations has an important place especially in erosion studies. The susceptibility of soil to erosion is the…
Over the years, developments in the world of science and technology have emerged. Developments in image classification methods can also be evaluated in this context. Nowadays, the use of image classification methods for extracting information from data obtaine…
Molecular interactions have been a hot topic in chemistry because of their importance in different processes from biological activities [1]. Quantum dots with strong and easily tunable luminescence and high emission quantum yields have become well-established …
Interior lighting profoundly affects health, perception, and comfort. This study investigates key lighting parameters—intensity, spectrum, exposure timing, and spatial layout—and their physiological and psychological effects. Based on scenario simulations, thi…
In the present study, a model drug, with its low permeable and low aqueous soluble properties, was selected to produce microparticles using an anti-solvent precipitation technique with two different drugs: polymer (0.5, 1.0, w/v %) ratios. The characterization…
Pseudomonas (P.) aeruginosa is Gram-negative an opportunistic human pathogen associated with nosocomial infections particularly immuno-compromised patients such as cystic fibrosis, cancer, and diabetes. This organism can also develop high-level intrinsic and a…
Schiff bases (known as imine or azomethine) exhibit interest as materials for wide spectrum applications, particularly as corrosion inhibitors, a metal ion complexing agents, in biological systems and thermo-stable materials. Schiff bases are an important cla…
Nowadays, nature-inspired structural colorization takes increasing attention due to its exceptional optical properties. One-dimensional (1-D) photonic crystals are new kind of optical materials which can be used to obtain structural colorization. In recent yea…
2020 yılına kadar büyük veri gereksinimi ile birlikte kullanıcı sayısının hızlı bir şekilde artmaktadır. Yeni nesil hücresel iletişim teknolojilerinin bu veri trafiği ile beraber daha yüksek veri hızlarını desteklemesi beklenmektedir. Yaklaşan 5.nesil (5th Gen…
İnsanın nasıl temiz içme suyu ve yaşam hakkı, en demokratik hakkıysa, soluduğu havanın da temiz ve sağlıklı olması en demokratik hakkıdır. İç ortamlar, insanların zamanlarının yaklaşık %80-90'ını geçirdiği kreşler, konutlar, okullar, resmi binalar, kapalı sp…
A serial hybrid optical amplifier composing of two amplification stages of erbium-doped fiber (EDF) amplifier covered C-band window and Raman fiber amplifier (RFA) covered L band window demonstrated. In this paper, the optimizations were done to obtain the opt…
In this study, the energy spectrum and wave functions of the hydrogen atom are discussed using the path integral method in complex space. The Path integral is easily applied to the harmonic oscillator problem. The problem of hydrogen atom is transformed into…
Along with development of electronics and software technology, amount of electromagnetic (EM) radiation, which expose to people, has significantly risen. For people who uses or do not use technology, it is of great importance that they should have enough inf…
Cellular phones are playing an important role in technological devices in today’s world. People start to use cellular phones at early ages. Even kids have their own cellular phones as a precaution for their security. However, researches evaluating long term …
Boundary-value problems with eigenparameter dependent boundary conditions is one of the most extensively developing fields in pure and applied mathematics. First, we cite the works of Walter and Fulton, both of which have extensively bibliographies, a discus…
Recently, the basis properties and eigenfunction expansions in various function spaces of the eigenfunction of the regular boundary value problems with spectral parameter in the boundary conditions have been investigated by many mathematicans. However in diff…
In this study, in an effort to develop polymer matrix composite materials, especially to be employed as workbench and kitchen bench usage, powdered waste porcelain was used as a filler to form satisfactory mechanical properties together with Salvadora persica …
