Since the mid-1980s Chinese calligraphy art has undergone a radical change and has opened itself to experimentation. Nowadays in China this artistic revolution has sparked a vivid debate among the art critics on three main topics: (1) definition of the phenomenon; (2) analysis of its nature; and (3) classification of the artistic production. In this article, all these aspects are analysed in order to give a comprehensive view of the present theoretical discussion and of its future development. 展开更多

In this paper we propose an automatic bandwidth control method for the performance improvement of Binary Amplitude Shift Keying (BASK) system for Giga-bit Modem in millimeter band. To improve the performance of the BASK system with a fixed bandwidth, the proposed method is to adjust a bandwidth of low pass filter in receiver using the fuzzy system. The BASK system consists of a high speed shutter of the transmitter and a counter and a repeater of receiver. The repeater consists of four stage converters, and a converter is constructed with a low pass filter and a limiter. The inputs to the fuzzy system are the reminder and integral of remainder of counter, and output is a bandwidth. We used a Viterbi algorithm to find the optimum detection from output of the counter. Simulation results show that the proposed system improves the performance compared to the fixed bandwidth. 展开更多

The global transformation processes are treated as contradictory. These processes are not as positive as the negative impact on the system of modem societies. Globalization as a popular ideology is based on the mythologizing of global neoliberal pseudo-integration, standardlization and unification. Thus it was formulated mythological discourse of global changes research. Apology of this mythological discourse became the intellectual foundation of globalization as a new social utopia. The article presents a critique of the mythological discourse of globalization. The ideology of globalization is interpreted as social dystopia. 展开更多

Today's society in Israel is divided and tom on many issues, including religion, and Jewish and Israeli identity, yet occasionally, a single event emerges which combines several divisions. One such issue is the "identity crisis" also known as the question of "Who is a Jew?". This is a thorny complex problem, and one which has not yet been awarded a clear-cut constitutional solution. For example, it continues to be debated whether the religious definition should be the decisive factor, that is, should a Jew defined as an individual born to a mother who is Jewish or has been converted according to halacha, or whether Israeli identity is the more critical element and whether any individual born in or immigrated to Israel who served in the army, works and pays taxes in Israel, and identifies with the state's values should be identified as a Jew? In this paper, the author wishes to focus on equally complicated issue, although one has attracted less attention. This is the issue of halachic polarization or extremism that characterizes Judaism in modem Israel. Following a brief historical explanation, the author defines the problem at hand, and propose a solution. 展开更多

Traditional houses decoration is a form of Chinese culture. In China, residential decorative art has a long history in the course of its development, which reflects the cultural spirit of Chinese ancient civilization. It ' s unique and rich artistic expression contains deep, traditional, and ethnic culture. It is an essential application element in our modem environment art design. Traditional houses decorated in a modem environment art design has a great significance in the inheritance, development and study of Chinese culture. In today' s world with a variety of cultural elements, more traditional Chinese art elements are to meet the requirements of our people, and are easily integrated with China in today' s art and culture. In recent years, more and more innovative art forms have been widely developed. This article will analyze and discuss traditional houses decorated in modem environmental art design. 展开更多

In this paper, a new principle for an adaptive line driver using Fuzzy logic is presented. This type of line driver can adapt its output impedance and gain, automatically to the applied load using a fuzzy logic controller (FLC). This results in automatically corrected output impedance for different cables with terminations. Also, the line driver output impedance and gain become insensitive to process and line variations. As an example, a line driver for ADSL application has been designed. The circuit operates from a 3.3 v in a 0.35 um standard CMOS technology. The power consumption of FLC is about 1 mW. The circuit dissipates 106 mW and exhibits a -62 dB THD for a 3.2-Vpp signal at 5 MHz across a 75 ohms Load. It has a relatively high -3 dB bandwidth (240 MHz) with good phase margin of about 67 degrees in a 10 pF load capacitor. 展开更多
