Equalitarian Societies are Economically Impossible

The inequality of wealth distribution is a universal phenomenon in the civilized nations, and it is often imputed to the Matthew effect, that is, the rich get richer and the poor get poorer. Some philosophers unjustified this phenomenon and tried to put the human civilization upon the evenness of wealth. Noticing the facts that 1) the emergence of the centralism is the starting point of human civilization, i.e., people in a society were organized hierarchically, 2) the inequality of wealth emerges simultaneously, this paper proposes a wealth distribution model based on the hidden tree structure from the viewpoint of complex network. This model considers the organized structure of people in a society as a hidden tree, and the cooperations among human beings as the transactions on the hidden tree, thereby explains the distribution of wealth. This model shows that the scale-free phenomenon of wealth distribution can be produced by the cascade controlling of human society, that is, the inequality of wealth can parasitize in the social organizations, such that any actions in eliminating the unequal wealth distribution would lead to the destroy of social or economic structures, resulting in the collapse of the economic system, therefore, would fail in vain

SEISMIC ANALYSIS OF T SHAPE RIGID BRIDGE WITH HIGH PIERS

ABSTRACT Combined with seismic resistance of T shape rigid bridge with high piers in Dina 2 gas-field of China, comparative analysis on double thin-wall piers and hollow thin wall pillar is carried out. Focusing on seismic performance of their dynamic properties and structure under the condition of one-way incentive and three-dimensional space incentive, we conclude that the seismic performance of double thin-wall piers is superior to hollow thin wall pillar, on the basis of the fact that double thin-wall piers contains more than hollow thin wall pillar low-frequency vibration frequency in sectional characteristic and pier under the condition of high basic agreement, which is easily causing to frequency dispersion

Image abstraction painting of flow-like stylization

U radu se predstavlja tehnika ne-fotorealističkog prikaza u kojoj se iz fotografije dobiva stilizirana apstraktna slika s tonovima koji se prelijevaju. Zasnovana na Kuwahara filtrima i integralnim spiralnim linijama, naša metoda simultano apstrahira oblike i boje, zadržavajući u isto vrijeme osnovna obilježja slika. Posebno razvijamo metodu proširenja i detekcije ruba i usmjeravamo pažnju na specifična obilježja i rubne dijelove slike. Predloženi je algoritam promjenljiv i iterativan te se stupanj prelijevanja tonova i apstrakcije može regulirati. Eksperimentalni rezultati pokazuju da je učinkovitost naše metode u postizanju koherentne i stilizirane apstrakcije zadovoljavajuća, uz zadržavanje osnovnih obilježja iz zadanih fotografija.This paper presents a non-photorealistic rendering technique for producing flow-like abstraction stylization from a photograph. Based on anisotropic Kuwahara filtering in conjunction with line integral convolution, our method abstracts shapes and colors simultaneously while preserving features of images. In particular, we develop an edge detection and dilation method, to draw attention to salient features and image boundaries. This proposed algorithm is incremental and iterative, and therefore the degree of flow and abstraction can be controlled. Experimental results demonstrate that the effectiveness of our method in producing a coherent and flow-like abstraction stylization is satisfactory yet preserving features and directions from photographs
