This paper describes the formulation and performance of a nonhydrostatic model featuring a unique variable stepped topography representation capable of capturing steep topographical slopes, while at the same time accurately representing subtle topography variations. The proposed enstrophy conserving formulation and the quasi-compressible closure cast on a multiply nested rotated spherical grid ...

Deep brain stimulation (DBS) of the subthalamic nucleus (STN) is the most common surgical therapy for Parkinson' s disease (PD). DBS of the pedunculopontine nucleus (PPN) is emerging as a promising surgical therapy for PD as well. In order to better characterize these nuclei in humans, we determined the anatomical connections of the PPN and STN and the topography of these connections using prob...

We present a theoretical and numerical study of the decay of an internal wave caused by scattering at undulating sea-floor topography, with an eye towards building a simple model in which the decay of internal tides in the ocean can be estimated. As is well known, the interactions of internal waves with irregular boundary shapes lead to a mathematically ill-posed problem, so care needs to be ta...

This paper shows how modern ideas of scaling can be used to model topography with various morphologies and also to accurately characterize topography over wide ranges of scales. Our argument is divided in two parts. We first survey the main topographic models and show that they are based on convolutions of basic structures (singularities) with noises. Focusing on models with large numbers of de...

the aim of this paper is to review the created problems and failure of environmental design patterns in designing process by designers. not respectfully addressing the context of environment during designing process have resulted in the loss quality of environment, damage to both nature and essence of environment as manifested in the case study area. methodology of the research was based on the...
