On the possible volume of $mu$-$(v,k,t)$ trades
A $mu$-way $(v,k,t)$ $trade$ of volume $m$ consists of $mu$ disjoint collections $T_1$, $T_2, dots T_{mu}$, each of $m$ blocks, such that for every $t$-subset of $v$-set $V$ the number of blocks containing this t-subset is the same in each $T_i (1leq i leq mu)$. In other words any pair of collections ${T_i,T_j}$, $1leq i< j leq mu$ is a $(v,k,t)$ trade of volume $m$. In th...
متن کاملبررسی طیف حجم (v,k,t) تریدهای ساده و اشتاینری و (v,k,t) تریدهای اشتاینری همگن
ترید دوگانه لاتین یک جفت از مربع های لاتین جزئی مجزا است که همان مجموعه از سلولهای غیر خالی پر شده است و سطر و ستون مربوطه همان مجموعه از ورودی ها را شامل می شود. همچنین می توان گفت که ترید لاتین زیر مجموعه ای از مربع لاتین جزئی است که می تواند با جفت متمایزش جایگزین شود و یک مربع لاتین جدید حاصل شود. ترید لاتین را d-همگن می نامیم، هرگاه پس از حذف سطرها و ستون های خالی، هر سطر و ستون دقیقاً d عض...
15 صفحه اولA Comprehensive Model for Stiffness Coefficients in V-Shaped Cantilevers
During past decade the AFM based nanomanipulation has been focus of attention as the promising nano fabrication approach. The main challenge in this process is the real-time monitoring. Consequently, the dynamic models have been proposed as a solution to the existing challenge. In the modeling approach the magnitudes of the forces are proportional to the stiffness coefficients o...
متن کاملThe CC-V Flap: A Novel Technique for Augmenting a C-V Nipple Reconstruction Using a Free Dermal Graft
BACKGROUND We present a novel method for augmenting the standard C-V flap used for nipple reconstruction with a free dermal graft which aims to improve the appearance of the nipple reconstruction, decrease loss of projection and improve patient satisfaction overall. METHODS The surgical technique for performing a free dermal graft augmentation of a CV flap is described. All patients who unde...
