Interference noising originating from the ultrasonic testing defect signal seriously influences the accuracy of the signal extraction and defect location. A method based on the translation invariant discrete wavelet transform (TIDWT) wavelet shrinkage was proposed for signal extraction according to the characteristics of the casting defect ultrasonic signal. Both simulated and actual steel defe...

Bu çalışmada hayvancılıkta yaygın bir şekilde kullanılan oksitetrasiklin (OTC) antibiyotiğinin sodyum ve hekzadesiltrimetilammonyum (HDTMA) ile modifiye edilmiş zeolite adsorpsiyonu incelenmiştir. Adsorpsiyon çalışmaları farklı OTC konsantrasyonları, çözelti pH’larında adsorbent dozajlarında yapılmıştır. izoterm verileri Freundlich modeline uygulanmıştır. HDTMA-zeolit antibiyotik giderimi pH’a ...

During study of directly spread spectrum systems, noted that this system uses many types code to data through communication process. There are different sequences available with good correlation properties, they often use pesudo sequence for spreading which is be less efficient in protecting information from the breaches attack communications systems penetration. In article gold will use, consi...

A setup of satellite ranging based on phsical random sequence is demonstrated, which has absolute security in information transmission because of the random property of the physical sequence. Using true random sequence replacing pesudo random sequence, synchronization technology is vital important for transmitted information demodulation, despreading and decryption. Based on the pricinple of te...

This paper provides a new generalization of fuzzy finite state machines, fuzzy transformation semigroups and their relationship. Consider a cubic structure, we introduce cubic finite state machines, cubic transformation semigroups, cubic successor, cubic exchange properties cubic subsystems, cubic submachines, cubic q-twins, cubic retrievable and study fundamental properties of them. We provide...

introduction relative dose computation is a necessary step in radiation treatment planning. therefore, finding an approach that is both fast and accurate seems to be necessary. the purpose of this work was to investigate the feasibility of natural cubic spline to reconstruct dose maps for linear accelerator radiation treatment fields in comparison with those of the simulation. materials and met...
