Short development life cycles, the importance of timeto-market and fast changes in technology influence the requirements engineering process. Requirements are exposed to changes during the entire development life cycle, and decisions related to requirements and system design are moving toward developers. For this reason it is important to keep requirement changes under control during the entire...

a simple method for fabrication of highly ordered gold nanorod film is introduced in this article. the procedure is based on thermal evaporation of gold into a porous anodic alumina film (paa). the ppa film was fabricated by combining the hard and mild anodization. this combination effectively decreases the processing time of fabrication of highly ordered porous anodic alumina film with control...
