In this work, a lumped-parameter Windkessel model of the cardiovascular system that simulates biomechanical parameters human physiology is presented. The object-oriented platform provided by MATLAB-based modeling environment SIMSCAPE employed to compute blood pressures and flows in each heart chamber at various sites vascular tree. hydraulic domain allows determination hemodynamics intuitively ...

The generation of mathematical models for the analysis buildings with multiple thermal zones is a large and complex task. Furthermore, order complexity dynamical model are increased by number included zones. To overcome this problem, paper presents an algorithm to define automatically, using geometric physics parameters as inputs. Additionally, spatial position each zone must be recorded in arr...

This paper analyzes voting on a linear income tax which is redistributed lump sum to the taxpayers. Individuals can evade taxes, which leads to penalties if evasion is detected. Since preferences satisfy neither single peakedness nor single crossing, an equilibrium may not exist. When it does exist, it may have interesting properties, in particular, the poor and the rich may form a coalition ag...

This paper shows that stricter enforcement may increase tax evasion. Individuals vote on a linear income tax which is used to finance lump sum transfers. Stricter enforcement may make redistributive taxation more attractive to the decisive voter. The tax rate and transfer may rise which in turn may increase tax evasion. An example shows that this result can actually occur. The paper also discus...

In this paper, conventional SAPO-34 and Cerium Hierarchical SAPO-34 zeolites are synthesized using a hydrothermal method for methanol-to-propylene (MTP) reaction. The Ce-H-SAPO-34 catalyst shows a slightly larger crystal size, bimodal pore size distribution (microporous and mesoporous) and lower surface acidity compared to conventional SAPO-34 catalysts. According to these physicochemical prope...
