In this paper we present the extension of the copula approach to ag-gregation functions. In fact we want to focus on a class of aggregation functions and present them in the multi linear form with marginal copu-lae. Moreover we will define also the joint aggregation density function.
On average, higher levels of such investments raise production by increasing the productivity of the labor force. While the significance of shortterm changes in business investment is less widely recognized, the importance of such changes for the business cycle has been known to economists since the beginning of the last century. For example, many believe that the current record expansion has b...
introduction: mineral trioxide aggregate is being widely used for root end filling, pulp capping, perforation repair, and other endodontic procedures. recently, a material similar to proroot mineral trioxide aggregate (pmta) was developed in iran named root mineral trioxide aggregate (rmta) with the claim of having the exact result of original mta. the purpose of this study was to compare the a...
زمینه و هدف: هدف از این مطالعه، ارزیابی توانایی مهروموم کنندگی آپیکال ضخامت های مختلف mta به صورت ارتوگرید (دسترسی مستقیم) در مقایسه با 5 میلی متر گوتاپرکا بود.روش بررسی: در این مطالعه از 50 دندان تک کانال کشیده شده انسانی استفاده شد. پس از آماده سازی کانال ها، دندان ها به صورت تصادفی به 4 گروه آزمایشی 10 تایی و 2 گروه 5 تایی کنترل تقسیم شدند. در گروه 1، ناحیه آپیکال کانال با گوتاپرکا و سیلر ah...
Minimizing Aggregate Movements for Interval Coverage
The main purpose of this paper is to assess the impact of the geometry and size of the aggregate, as well as the drying temperature on the compressive strength of the ordinary concrete. To this end, two aggregates with sharp and round corners were prepared in three different aggregate sizes. After preparing concrete samples, the drying operations were carried out in the vicinity of room tempera...
Two classes of aggregation functions: L-statistics and S-statistics and their generalizations called quasi-L-statistics and quasi-S-statistics are considered. Some interesting characterizations of these families of operators are given. The aforementioned functions are useful for various applications. In particular, they are very helpful for modeling the socalled Producer Assessment Problem.
