در این کار پژوهشی، نمونه‌های هیدروکسی اپتایت آلاییده با ناخالصی‌های سریم، گادولونیم و ترکیبی از دو ناخالصی به روش هیدروترمال سنتز شدند. منظور بررسی فازهای بلوری تشکیل یافته هرکدام شده، کد MAUD که یک نرم‌افزار برای تجزیه تحلیل ساختار ماده استفاده پراش بر اساس ریتولد است، شد. پاسخ دزیمتری ترمولومینسانس نمونه‌ها مورد قرار گرفت یافته‌ها نشان داد نمونه‌ ترکیبی، سطح میانی است. مشخص شد افزودن سریم می‌...

This paper studies market schemes in which auctions are used to coordinate the buyer and competing suppliers in a procurement setting. While auction is typically considered a price-determination mechanism, it could also serve as a coordination mechanism. Possible auction and market mechanisms and their expected payoffs are analyzed in a two-supplier, one-buyer system. The auction mechanism coul...

We develop a game-theoretic framework to investigate the competitive implications of consumer-to-consumer electronic marketplaces, which promote concurrent selling of new and used goods. In many e-marketplaces, where suppliers cannot directly use second-hand goods for practicing inter-temporal price discrimination, the threat of cannibalization of new goods by used goods become significant. We ...

Relationship duration, supplier autonomy, and customer status affect the performance of suppliers of modular and architectural components differently. Data on U.S. carburetor and clutch manufacturers from 1918 to 1970 shows that suppliers of architectural goods (carburetors) benefit from high status customers, current autonomy, and, to a lesser extent, long-term relationships. Only autonomy aff...

UNLABELLED The short-comings of current anticoagulants have led to the development of newer, albeit more expensive, oral alternatives. OBJECTIVE To explore the potential impact the new anticoagulants dabigatran and rivaroxaban in the local hospital setting, in terms of utilisation and subsequent costing.

There are many methods to analyze motion in computer vision. Most of the classical methods use optical flow, layered motion or segmentation. Optical snow is a complex motion estimation scenario which analyzes motions such as snowfall, tree movements, cars traffic and people walking. These scenes are made of many different objects, moving in different speeds in various directions. While analyzin...
