Chemical–mechanical polishing (CMP) is a process that planarizes semiconductor surfaces and essential for the manufacture of highly integrated devices. In CMP, pad conditioning using disk with diamond grit adopted to maintain surface roughness remove debris. However, uneven wear by unavoidable in CMP. this study, we propose contact-area-changeable system utilize it conduct preliminary study imp...

While fuzzy systems can advantageously be used in system modeling and control, their use in time-critical applications is limited because of complexity problems, especially in cases, when not only low, but also flexibly changeable complexity is needed. Previously a method has been proposed to use fuzzy and other soft-computational tools in the frame of modular anytime architectures, however, th...

The proposed method is based on 2-dimensional quantization of distance vectors between biometrics features and pairs of random vectors in this method the concept of changeable cryptographic key generation using face biometrics signal. A previously introduced scheme, fuzzy vault, is utilized for secure binding of randomly generated key with extracted biometrics features. The major technical diff...

Mining frequent patterns in a data stream is very challenging for the high complexity of managing patterns with bounded memory against the unbounded data. While many approaches assume a fixed support threshold, a changeable threshold is more realistic, considering the rapid updating of the streaming transactions in practice. Additionally, mining of itemsets over various time granularities rathe...

This paper analyzes the conflict between performance enhancing technology and IPSec in satellite IP networks, and proposes a solution called multilayer IP security with changeable zone (CZML-IPSec). It enables licensed intermediate nodes not only access TCP header, but also object links of upper layer in the form of HTML by converting static zone mapping to changeable dynamic mapping and buildi...

The optical-transport properties of 1D Se-doped CdS nanostructures with different doping contents and/or crystallization degrees are reported. The locally excited photoluminescence shows a significant redshift during the transport along the long axis of the 1D structures and can leave enough PL intensity for detection. The magnitude of the redshift is found to be highly dependent on the content...

Photochromism is a chemical process in which a compound undergoes a reversible change between two states having separate absorption spectra, i.e. different color [1]. In our previous work we have published some solutions of problems of measuring photochromic textile sample by standard commercial spectrophotometric systems [2]. Main problem with measurement of kinetic behavior of photochromic pi...
