flow field and heat transfer of a nanofluid, whose non-newtonian behavior has been demonstrated in the laboratory, in a square enclosure have been numerically modeled and investigated. to estimate the viscosity of nanofluid, experimental data of hong and kim, 2012 have been used, and a new model has been proposed. finally, the obtained results have been compared to those of newtonian behavior. ...

Long-term seafloor geodetic measurements are important for constraining submarine crustal deformation near plate boundaries. Here we present an integrated analysis of a decade GNSS/acoustic data collected at site 60 km to the east northeast Taiwan axis Okinawa Trough back-arc basin. We obtained time-series horizontal and vertical positions based on 18 from 2009 2019. These reveal southeastward ...

The main problem addressed in this work is how to confine the set of sequential processes of a disjunctive / conjunctive resource allocation system (D/C-RAS) to a subset of their feasible behaviors while optimizing some performance criterion. We provide a canonical characterization of this problem in the form of a Mixed Integer Programming (MIP) formulation, for the case that the optimized perf...

Three-dimensional animation sequences are often represented by a discrete set of compatible triangle meshes. In order to create the illusion of a smooth motion, a sequence usually consists of a large number of frames. We propose a pre-processing algorithm that considerably reduces the number of frames required to describe the whole animation. Our method is based on Batch Neural Gas [11], a new ...

Thinning operation is a fundamental operation in image processing. It is a typical preprocessing stage for pattern recognition and data compression. In this report we proposed an algorithm that performs thinning operation by using reconfigurable mesh RMESH multiprocessors. The time and space complexities are both O(1) and therefore optimal.

In this paper we approximate large sets of univariate data by piecewise linear functions which interpolate subsets of the data using adaptive thinning strategies Rather than minimize the global error at each removal AT we propose a much cheaper thinning strategy AT which only minimizes errors locally Interestingly the two strategies are equivalent in all our numerical tests and we prove this to...

One of the important issues in many of array systems such as Radar, Sonar, Mobile, and satellite telecommunications is the estimation of DOA of narrowband received signal. CRB is very important in evaluation of parameter estimation. CRB is the lower bound estimation error variance for any unbiased estimation. In this paper, the array antenna with equal distance arrays is extended in two separat...

Detailed knowledge of the lithospheric structure is essential for a better understanding tectonic evolution Xing'an-Mongolian Orogenic Belt (XMOB). We constrained across XMOB by receiver function imaging and shear wave splitting analysis from dense seismic array. The lithosphere-asthenosphere boundary (LAB) coherently imaged in different blocks. mid-lithospheric discontinuity also identified at...
