The change of land use/land cover has been known as an imperative force in environmental alteration, especially in arid and semi-arid areas. This research was mainly aimed to assess the validity of two major types of land change modeling techniques via a three dimensional approach in Birjand urban watershed located in an arid climatic region of Iran. Thus, a Markovian approach based on two suit...

In this paper, we present a multi-formalism modeling framework (abbreviated by MFMF) for modeling and simulation. The proposed framework is defined based on the concepts of meta-models and uses object-orientation to overcome the complexities and to enhance the extensibility. The framework can be used as a basis for modeling by various formalisms and to support model composition in a unified man...

In this paper, the energy absorption features of tri-layer explosive-welded deep-drawn cups subjected to quasi-static axial compressive loading are investigated numerically and experimentally. To produce the cups, tri-layer blanks composed of aluminum and stainless steel alloys were fabricated by an explosive-welding process and formed by a deep drawing setup. The quasi-static tests were carrie...

ABSTRACT In this paper, we report multi-level storage (MLS) in multi-layer (ML) and single-layer (SL) phase-change memories (PCM). For the former ML-PCM device, the active medium with two layers of chalcogenide consists of a top 30-nm TiN/180-nm SbTeN/20-nm TiN/bottom 120-nm SbTeN stacked multi-layer. Three stable and distinct resistance states are demonstrated in both static and dynamic switch...

Underwater images are firmly low quality by a mixture of noise, wavelength dependency, light attenuation. This paper depicts effective strategy to improve the de...
