امروزه تخمین حرکت بلوک در تصاویر بر اساس روش هایی که تمام جزئیات را شامل می شوند، تبدیل به یک مبحث فراگیر در شاخه ی پردازش تصویر گشته است. چرا که از جمله ی روش هایی به حساب می آید که باعث فشردگی و کاهش حجم داده های تصویری می گردد. جهت تحقّق این هدف، الگوریتم های متفاوتی ارائه شده اند. الگوریتم های جستجوی محلی، جستجوی پیشگویانه و... که با توجه به نیاز مسأله انتخاب و مورد استفاده قرار می گیرند، از...
A novel intramolecular Prins type cyclisation of cyclopropylvinylic aldehydes promoted by TiCl(4) under mild reaction conditions to form cis-cyclic products in high yields has been accomplished.
A large database of invasive forest pathogens (IFPs) was developed to investigate the patterns and determinants of invasion in Europe. Detailed taxonomic and biological information on the invasive species was combined with country-specific data on land use, climate, and the time since invasion to identify the determinants of invasiveness, and to differentiate the class of environments which sha...
Digital light processing (DLP) can produce small series ceramic parts with complex geometries and tiny structures without the high cost of molds usually associated traditional processing. However, availability feedstock different ceramics for technique is still limited. Mullite-zirconia composites are refractory materials diverse applications, nevertheless, their 3D printing has never been repo...
Titanium and its alloys have been used in a broad range of products such as biomedical implants due to their high specific strength, corrosion resistance, biocompatibility. Improvement microstructure mechanical properties commercially pure (CP) titanium is usually performed by cold rolling controlled atmosphere heat treatment. However, this an energy-intensive, expensive, multi-stage process ac...
