application of upfc based on svpwm for power quality improvement

در سالهای اخیر،اختلالات کیفیت توان مهمترین موضوع می باشد که محققان زیادی را برای پیدا کردن راه حلی برای حل آن علاقه مند ساخته است.امروزه کیفیت توان در سیستم قدرت برای مراکز صنعتی،تجاری وکاربردهای بیمارستانی مسئله مهمی می باشد.مشکل ولتاژمثل شرایط افت ولتاژواضافه جریان ناشی از اتصال کوتاه مدار یا وقوع خطا در سیستم بیشتر مورد توجه می باشد. برای مطالعه افت ولتاژ واضافه جریان،محققان زیادی کار کرده ...

Bio-inspiration: Learning Creative Design Principia

Reusing or modifying known design concepts cannot meet new challenges for engineering systems. However, engineers can find inspiration outside their traditional domains in order to develop novel design concepts. The key to progress and knowledge acquisition is found in inspiration from diverse domains. This chapter explores abstract knowledge acquisition for use in conceptual design. This is ac...

Providing metrics and automatic enhancement for hierarchical taxonomies

Taxonomies enable organising information in a human-machine understandable form, but constructing them for reuse and maintainability remains difficult. The paper presents a formal underpinning to provide quality metrics for a taxonomy under development. It proposes a methodology for semi-automatic building of maintainable taxonomies and outlines key features of the knowledge engineering context...

Hybrid Architecture for Web Search Systems Based on Hierarchical Taxonomies

Search systems based on hierarchical taxonomies provide a specific type of search functionality that is not provided by conventional search engines. For instance, using a taxonomy, the user can look for documents related to just one of the categories of the taxonomy. This paper describes a hybrid data architecture that improves the performance of restricted searches for a few categories of a ta...
