The role of nanotechnology in protection
Nanotechnology is a new science and the revolution of the twenty-first century. There is a serious promising applications for nanotechnology that we can use in many fields, Such as (cosmetics, textiles, healthcare, tissue engineering, catalysis, functional coatings, medical diagnosis and therapeutics, sensors , communication engineering and water and air pollution treatment). It plays an essential role in protection by using it in sterilization and giving distinct results , it was also used to eliminate bacteria and viruses by incorporating nanofilter with many material containing the ability to reduce reproduction of bacteria or eliminating it. We have several examples of these materials like ( Copper (II) oxide, silver , graphene ) . Because of these unique features , nanofiber has been used in many filters types like ( air nanofilter , water nanofilter , oil nano filter ....etc.) But the specific type that interests us uses nanofilter in face masks.
Sequences and Their Applications – SETA 2006 ; 4th International Conference, Beijing, China, September 24-28, 2006, Proceedings
PrefaceThis volume contains the refereed proceedings of the Fourth International Con-ference on Sequences and Their Applications (SETA 2006), held in Beijing, Chinaduring September 24–28, 2006. The previous three conferences SETA ’98, SETA2001, and SETA 2004 were held in Singapore, Bergen, and Seoul, respectively.The SETA conferences are motivated by the numerous applications of sequencesin modern communication systems. These applications include pseudorandomsequences in spread spectrum, code-division-multiple-access, stream ciphers incryptography, and several connections to coding theory and boolean functions.

This volume contains the refereed proceedings of the 3rd International Conf- ence on Sequences and Their Applications (SETA 2004), held in Seoul, Korea during October 24-28, 2004.
Radio Frequency Integrated Circuits and Technologies ; 2nd ed.
The operation frequencies, bandwidths and data capacities of communications systems are continuously increasing by employing advanced technologies and aggressive scaling of device dimensions. However, the restrictions inherent in scaling make the design of radio frequency integrated circuits a demanding task. To meet the corresponding challenges designers must provide profound skills in several areas including circuit theory, silicon and compound semiconductor technologies, communications standards, system design, measurement techniques, etc. The book aims at addressing all these multidisciplinary issues in a compact and comprehensive form and in a single volume. Suitable for students, engineers and scientists, the manuscript offers the necessary theoretical background together with cookbook-like optimisation strategies and state-of-the-art design examples."

An Interactive Multimedia Introduction to Signal Processing
A didactic concept is undertaken for microelectronics, computer technology and communication engineering, which deals with the visualization of signals and processes in addition to graphical programming of signal processing systems. Through the utilization of a professional and globally supported software for metrology and control engineering, DasyLab, useful applications can be developed, modified and optimized. Computer supported processing of real signals is made possible over the sound card and the parallel port. Over two hundred pre-programmed signal engineering systems and design transparencies are provided. Pictures also play a dominant rule in this book: there are numerous introduction-videos, one for every chapter, more than 250 high-quality pictures and - most important – all the "living" experiments and their results are visualized. With this learning system, readers can now make use of "equipment" and software, which was practically unaffordable for individuals in the past. What's more, here is a very new concept for learning Signal Processing, not only from the physically-based scientific fundamentals, but also from the didactic perspective, based on modern results of brain research.
