It is well known that non-Gaussian noise deteriorates the detection performances of the conventional detection methods. This problem is also encountered in cognitive radio where impulsive structure of noise negatively affects spectrum sensing. Multistage detec…

Parasitic capacitance has adverse effect on capacitive micromachined ultrasonic transducer (CMUT) performance. Reduction of parasitic capacitance, therefore, is essential for high performance CMUT device. Isolation layer between two electrodes of CMUT is one o…

Eğitim sektörünün giderek büyüyen yapısında, yükseköğretim kurumları, öğrenci performansının akademik olarak iyileştirilmesi ve öğrencilerin okulu bırakmalarını önlemek için veri madenciliği araçlarını ve tekniklerini kullanmaktadır. Veriler sosyo-ekonomik, de…

Prediction in the medical field is a challenging problem and as a result many researchers have used different artificial intelligent methods including conventional Self Organizing Map (SOM) to achieve this task. SOM is a specialized clustering technique that h…

Supplier selection and measurement of supplier performance are multiple criteria decision making (MCDM) problems and have a strategic importance for all industries. Supplier performance measures is a tool to determine whether suppliers are doing their job as e…

In this study, the literature review on the user perceptual assessment of the colour used in the interior space is analyzed and grouped. Most of the studies are about the perception of colours throughout the space. However, it is thought that the colour combin…

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…

Chronically, the Nigerian pharmaceutical arena has witnessed a series of scandals, perhaps unprecedented level of unethical behaviors, cruelty or of a kind. These events have seriously shaken people’s belief. In general, such activities have left a black-hole …
