Effect of Activated Carbon Parameters on the Surface Properties of Wheat Straw Residue
(IBCESS, 2016)Activated carbon has perfectly developed porosity, a large surface area (up to 3500 m2 g-1), and modifiable surface chemistry properties and exhibits a comparatively high degree of surface reactivity. Due to these reasons, ... -
De Moivre Eşitliği ve Trigonometrik İlişkiler ile Gerçeklenen Sayısal Kontrollü Osilatör
(IEEE, 2015)Sayısal haberleşme sistemlerinde önemli bir yere sahip olan sayısal kontrollü osilatörlerde, kontrol edilebilirlik ve kararlılık özellikleri nedeniyle tablo tabanlı yapılar tercih edilmektedir. Bu çalışma, faz artımı ... -
De Moivre Eşitliğini Kullanan Sayısal Osilatör
(IEEE, 2015)Sayısal haberleşme sistemlerinde frekansı sayısal kontrollü sinüsoidal işaret üretimi için, kararlılık ve kontrol edilebilirliklerinden dolayı, hafıza tabanlı işaret üreteçleri kullanılmaktadır. İşaretlerdeki kalite ... -
Multipllier- free Raised-cosine Filter for Binary Streams Using DDS
(IEEE, 2014)Raised-Cosine filters with over-sampled input/output are used to limit spectral bandwidth of the communication signals. Over-sampling inherently increases the number of required components in FIR filters. We aimed to reduce ... -
A Numerically Controlled Oscillator Based on De Moivre's Identity and Linear Approximation
(IEEE, 2015)Discrete sinusoidal quadrature signal generators whose output frequency is numerically and instantaneously controlled are in widespread use in digital communication systems. In this paper, a numerically controlled ... -
Preparation and Characterization of High Purity Silica Obtained from Rice Husks
(Polish Academy of Sciences Institute of Physics, 2017)Although SiO2 is produced mostly from mineral sources like quartz, it has recently been obtained from lignocellulosic natural resources, such as rice husk (hull). Several methods for extracting silica (SiO2) from rice husks ... -
SAR Görüntülerindeki Arazi Alanlarının Bölge-Tabanlı Segmentasyonu
(IEEE, 2020)Sentetik Açıklıklı Radar (SAR) görüntüleri günümüzde çok çeşitli alanlarda yaygın olarak kullanılmaktadır. SAR görüntülerindeki görüntü benekleri ve piksel benzerliklerinden dolayı görüntü segmentasyonu oldukça zordur. Son ... -
Social, historical and international aspects of space research
(IEEE, 2015)Men has completed the phase “globalization” on Earth by conquering almost all parts of the globe, by using almost all resources offered by this planet, in a collaborative way involving all habitants. Now it is time to ... -
ULTRASONIC MODIFICATION EFFECT OF ACTIVATED CARBONS ON THE REMOVAL OF ARSENIC IN WASTERWATERS
(İKSAD, 2020)Arsenic contamination is a global threat and challenge humankind faces due to its carcinogenic and toxic effects on humans and environment. Typical arsenic removal methods in wastewaters are Oxidation-precipitation, ...
