Optimal beaconing control for epidemic routing in delay tolerant networks
No full textOwing to the uncertainty of transmission opportunities between mobile nodes, the routing in delay-tolerant networks (DTNs) exploits the mechanism of opportunistic forwarding. Energy-efficient algorithms and policies for DTN are crucial to maximizing the message delivery probability while reducing the delivery cost. In this contribution, we investigate the problem of energy-efficient optimal beaconing control in a DTN. We model the message dissemination under variable beaconing rate with a continuous-time Markov model. Based on this model, we then formulate the optimization problem of the optimal beaconing control for epidemic routing and obtain the optimal threshold policy from the solution of this optimization problem. Furthermore, through extensive numerical results, we demonstrate that the proposed optimal threshold policy significantly outperforms the static policy with constant beaconing rate in terms of system energy consumption savings
The history of Tsai-Li (Abiding Principle) Sect and its educational impact in Taiwan, 1950-1980
No full textPueligion is one of the most important aspects of culture. It shapes people's relationships with each other, influencing family, school, community, economic, and political life. It finds expression in human behavior, and in value systems. In the study of religion and moral education a need exists to identify the faith of the religion in relation to the cultural background of its people. The religion of Tsai-li (Abiding Principle), since its establishment over three hundred sixty years ago in China, functions as a part of the social structure. It represents the unity of three religions; each contributes to the unifying principle of Tsai-li: the teaching of the preservation of life and the attainment of longevity is from Taoism, the cultivation of life and the achievement of enlightenment is from Buddhism, and the teaching of the establishment of life and the realization of one's destiny is from Confucianism. This study sought to trace the historical development of the establishment of the Tsai--li Sect in Taiwan from 1950-1980, with the primary goal of analyzing and describing the Confucian Li (Propriety) as the Li (Principle) in the ethical teaching of Tsai-li, which is relevant to the contents of moral education. In addition, the major rituals of the Tsai-li Sect are under examination based on functionalist theory in the light of the Tsai-li's moral function in the Taiwanese society. The following research questions guided the direction of the study: What are the ethical teachings of the Tsai-li Sect which are relevant to moral education? What do the major rituals of the Tsai-li Sect symbolize, and what are their moral implications? What are the functions, manifest and latent, of Tsai-li's institutional development and what is their effect upon education in Taiwan during the period of 1950-1980? The research analysis indicates that the Tsai-li’s ethical teachings, the Confucian Li (Propriety), reflect the central values either in the school's moral education or in the Taiwanese society. And its religious rituals and participation in national social and political activities maintain its religious solidarity in a well-ordered society.Education, College o
Cryphalus lipingensis Tsai & Li, 1963
No full textCryphalus lipingensis Tsai & Li, 1963 belongs to the bark beetle genus Cryphalus that contains more than 200 species. Five species of Cryphalus are distributed throughout the USA, mostly in northern latitudes. All American species live in dead twigs of conifers, and none of these species is considered an important pest. Cryphalus lipingensis does not occur in North America, but it is widespread in China. The reason for its importance is that it has been reported to colonize and kill American pine species planted in China, namely slash pine, Pinus elliottii, and as such poses a threat to US forests and forestry as a potential invasive pest
Ming-Jer Tsai oral history interview
No full textThis recording and transcript form part of a collection of oral history interviews conducted by the Chao Center for Asian Studies at Rice University. This collection includes audio recordings and transcripts of interviews with Asian Americans native to or living in Houston.Dr. Ming-Jer Tsai is currently a professor at Baylor College of Medicine in the Department of Molecular and Cellular Biology. He was born in Taichung, Taipei, the third eldest in a family of six children. He studied at the National Taiwan University before immigrating to the United States to get his Ph.D. in Biochemistry at the University of California, Davis. During the interview, he talked about the mentorship styles and the politics involved in the research field. He also talked about how the results of his research on COUP-TFII can help patients in the future
Successive-relaying-aided decode-and-forward coherent versus noncoherent cooperative multicarrier space–time shift keying
No full textAbstract—Successive-relaying-aided (SR) cooperative multi-carrier (MC) space–time shift keying (STSK) is proposed for frequency-selective channels. We invoke SR to mitigate the typical 50% throughput loss of conventional half-duplex relaying schemes and MC code-division multiple access (MC-CDMA) to circumvent the dispersive effects of wireless channels and to reduce the SR-induced interference. The distributed relay terminals form two virtual antenna arrays (VAAs), and the source node (SN) successively transmits frequency-domain (FD) spread signals to one of the VAAs, in addition to directly transmitting to the destination node (DN). The constituent relay nodes (RNs) of each VAA activate cyclic-redundancy-checking-based (CRC) selective decode-and-forward (DF) relaying. The DN can jointly detect the signals received via the SN-to-DN and VAA-to-DN links using a low-complexity single-stream-based joint maximum-likelihood (ML) detector. We also propose a differentially encoded cooperative MC-CDMA STSK scheme to facilitate communications over hostile dispersive channels without requiring channel estimation (CE). Dispensing with CE is important since the relays cannot be expected to altruistically estimate the SN-to-RN links for simply supporting the source. Furthermore, we propose soft-decision-aided serially concatenated recursive systematic convolutional (RSC) and unity-rate-coded (URC) cooperative MC STSK and investigate its performance in both coherent and noncoherent scenarios
The political role of the people's liberation army 1949-1973
Full text linkThis thesis is to study the political role of the People's Liberation Army from the approach of structure and function. The framework of the thesis consists of three major parts, first, the influence of Chinese traditional political culture on, and the formation of, the political role of the PL A; second, the influence of domestic political struggles and external military conflicts on the development of the political role of the PLA; and the third, the analysis of the transition of the PLA's political role from the structure and personnel arrangements of the CCPCC Within the above-mentioned three scopes, this thesis make a thorough discussion on the following: (1) The relationship between the structure of the PRC and the formation of the PLA's political role; (2) How has ideology influenced the army's political role; (3) What is Mao's viewpoint and his influence on the development of the army's political role; (4) What is the link between the army and the party, and how has this developed; (6) What accounts for the expansion of the PLA's political functions; (7) What is the influence of political factional struggles on the PLA's political role; (8) Is it political institution or military institution that controls the recruitment of the military elite; (9) What are the disparities between the military elite in handling international conflicts and what are their political considerations; (10) What is the Party's position in the army; (11) How have the Party’s important meetings and personnel arrangements influenced the rise and fall of the PLA's political role
