quantifying urban landscape is fundamental for monitoring and assessing ecological and socioeconomic consequences of urbanization. expansion of roads is a significant factor driving urban landscape change. the aim of this research is quantifying impacts of roads on isfahan city landscape. to achieve this aim, land use map of isfahan was created in 6 classes: urban, green spaces, agricultural, b...

Computational network analysis provides new methods to analyze the human connectome. Brain structural networks can be characterized by global and local metrics that recently gave promising insights for diagnosis and further understanding of neurological, psychiatric, and neurodegenerative disorders. In order to ensure the validity of results in clinical settings, the precision and repeatability...

Software Security metrics are quantitative measures related to a software system’s level of trustworthiness. They can be used to aid in resource allocation, program planning, risk assessment, and product and service selection. Recently researchers have proposed several software security metrics. Among these are attack surface and vulnerability density. The attack surface measure has been used b...

‎We study curvature properties of four-dimensional Lorentzian manifolds with two-symmetry property‎. ‎We then consider Einstein-like metrics‎, ‎Ricci solitons and homogeneity over these spaces‎‎.

Placement is a key step in VLSI physical design cycle. With aggressive scaling if VLSI to Very Deep submicron level lead to higher power density which lead to generation on non uniform thermal map and hotspots. This scenario represent an important challenge in VLSI physical design to generate a layout that distribute temperature uniformly while optimizing traditional metrics like area, power an...

in this paper, we study a class of finsler metrics which contains the class of p-reducible andgeneral relatively isotropic landsberg metrics, as special cases. we prove that on a compact finsler manifold,this class of metrics is nothing other than randers metrics. finally, we study this class of finsler metrics withscalar flag curvature and find a condition under which these metrics reduce to r...
