Supporting 'Design for Re-use' with Modular Design

Engineering design reuse refers to the utilization of any knowledge gained from the design activity to support future design. As such, engineering design reuse approaches are concerned with the support, exploration, and enhancement of design knowledge prior, during, and after a design activity. Modular design is a product structuring principle whereby products are developed with distinct module...

Expressing variability for design patterns re-use

A design pattern description is much more complex than a semi-formal solution, often restricted to a class diagram. Applying a pattern mainly depends on the solution specification but a lot of useful information can be found into other items. Neglecting variants of the main solution the pattern engineer might explain can be detrimental to the pattern itself because, most of the time, they affec...

Re-design of Downstream Processing Techniques for Nanoparticulate Bioproducts

There has been much interest generated in the recovery of nanoparticulate (nanoparticle) bioproducts(Second generation of biotechnological products) such as plasmid DNA and viruses as putative gene therapyvectors, macromolecular assemblies as drug delivery vehicles and virus-like particles as vaccine components.Such product must be manufactured in advanced stages of purity, ma...

تحلیل موتور توربوپراپ در شرایط on-design و off-design

در این رساله عملکرد یک موتور توربوپراپ که ملخ آن از نوع clark y 5868-r9 است در شرایط نقطه طرح (on- design) و خارج از نقطه طرح (off- design) مورد مطالعه قرار گرفته شده است. موتور توربوپراپ یکی از انواع موتور جت در تراست بالا و مصرف مخصوص سوخت پایین است که عدد ماخ پروازی آن هرگز از 8/. تجاوز نمی کند. دور موتور های توربوجت به حدی زیاداست که در صورت اتصال مستقیم به ملخ، سرعت نوک تیغه های ملخ به سرع...
