As special depositional environments which are adjacent to the seas, deltas have provided a field for human habitat establishment. Geomorphic features of deltas are in constant transformation due to their dynamic features. Constructing dams on rivers can intensify these changes and cause either negative or positive consequences. Minab delta in Hormozgan Province of Iran is a round or crescent-s...

Pollination is an ecological service with high economic values related to human and ecological wellbeing. This study aims to evaluate the correlation between landscape complexity and pollination service (bee) in Qazvin province at the landscape scale. Landscape pattern metrics (Number of Patches (NP), Patch Richness (PR), Edge Density (ED), and Shannon Index (H)), as a proxy of landscape comple...

In this paper, by using the concept of spherically symmetric metric, we defne the notion of λ-projectively related metrics as an extension of projectively related metrics. We construct some non-trivial examples of λ-projectively related metrics. Let F and G be two λ-projectively related metrics on a manifold M. We find the relation between the geodesics of F and G and prove that any geodesic of...

در سال های اخیر هندسه فینسلر نه تنها به عنوان موضوعی مدرن که شامل قضایا و تکنیک های متعدد می باشد مطرح است، بلکه بعنوان موضوعی مهم در حل مسایل ترمودینامیک، اپتیک، اکولوژی، بیولوژی و ... پیشرفت های چشم گیری داشته است. در این پایان نامه متریک های ریشه m-ام تعمیم یافته، روی یک منیفلد n-بعدی m را مورد بررسی قرار می دهیم که خواص جبری خاصی دارند. در مقاله(on einstein m-th root metrics)، نویسندگان خوا...

– in this paper we consider some (α ,β ) -metrics such as generalized kropina, matsumoto and f (α β )2α = + metrics, and obtain necessary and sufficient conditions for them to be einstein metrics when βis a constant killing form. then we prove with this assumption that the mentioned einstein metrics must beriemannian or ricci flat.

This paper reports results from an experiment that was aimed at comparing evaluation metrics for machine translation. Implemented as a workshop at a major conference in 2002, the experiment defined an evaluation task, description of the metrics, as well as test data consisting of human and machine translations of two texts. Several metrics, either applicable by human judges or automated, were u...

environmental degradation model is one of the environmental impact assessment (eia) methods in which ecological cumulative effects of human activities on his surrounding nature could be evaluated and quantified. as a special trait of landscape ecological metrics is the ability of rapid assess and recognize of human activities in the shortest time. thus in this study, we used a landscape degrada...

We present a comparative study on Machine Translation Evaluation according to two different criteria: Human Likeness and Human Acceptability. We provide empirical evidence that there is a relationship between these two kinds of evaluation: Human Likeness implies Human Acceptability but the reverse is not true. From the point of view of automatic evaluation this implies that metrics based on Hum...

Human-swarm interaction is an emerging field encompassing questions related to biology, robotics, computer science, human-computer interaction, and psychology. Swarms are large groups of individual entities that enact group behaviors; biological examples include fish, birds and insects. Swarms overwhelm humans’ abilities to monitor and interact with each entity. Human-robot and human-computer i...
