owing to the oncoming needs and increasing the population of lake urmia watershed, providing equilibrium between water supply and demand seems quite challenging and the lake cannot be successful in meeting its ecological demands in this critical condition. in this unfavorable situation, water resources must be managed through a sustainable context. with this knowledge in hand, a multi attribut...
19 juvenile members of known genealogies in two wild baboon groups were studied over a 16month period to compare the ontogeny of agonistic experience and dominance relations for males and females. Juveniles of all age-sex classes were disproportionately likely to receive aggression from and submit to adult males per unit of time spent in proximity. This pattern intensified with increasing juven...
This paper proposes a novel automatic pronunciation scoring framework using learning to rank. Human scores of the utterances are treated as ranks and are used as the ranking ground truths. Scores generated from various existing scoring methods are used as the features to train the learning to rank function. The output of the function is then segmented by the proposed DP-based method and hence b...
We introduce various notions of rank for a high order symmetric tensor, namely: rank, border rank, catalecticant rank, generalized rank, scheme length, border scheme length, extension rank and smoothable rank. We analyze the stratification induced by these ranks. The mutual relations between these stratifications, allow us to describe the hierarchy among all the ranks. We show that strict inequ...
In this paper we prove Vaught's conjecture for superstable theories in which each complete type has nite U? rank. The general idea is to associate with the theory an V ? deenable group G (called the structure group) which controls the isomorphism types of the models. We use module theory to show that when the theory has few countable models and M is a countable model there is a nice decompositi...
This paper tries to determine the most vulnerable points of high–income countries during Covid-19 pandemic in an MCDM setting. For this aim, we use entropy method obtain criteria weights and PIV for comparisons. We employ a wide range that account political, demographic, capacity, indicators including vaccination. Our sample consists 40 HICs. The results reveal with less equitable healthcare sy...
اگر~ یک رابطه روی r^n باشد وt یک عملگر خطی از r^n به r^n باشد، t را نگه دارنده خطی ~ کوییم هرگاه tx~ty، x~y را نتیجه دهد.t را نگه دارنده قوی ~ گوییم هرگاه x~y اگر و تنها اگر tx~ty . برای دو بردار x,y در r^n گوییم y بردار احاطه ساز سه قطری تعمیم یافته x است (باx?_gt y نمایش داده می شود) هرگاه ماتریس سه قطری تصادفی مضاعف d وجود داشته باشد به طوری که x=dy. علاوه بر این اگر y?_gt x آن را با نماد x~...
