    The Buddha's Dialogue as the Origin (Causes) and Destiny (Conditions) of the Buddhist Culture: A Hermeneutical Approach 

    Unknown author (The colloquium on the theme: "Origins and destinies of Cultures", co-organized by Graduate Programs of Philosophy and Religion, Assumption University, and FABC, during 4-5 June, 2013 at ABAC, Suwannabhumi Campus. Thailand, 2013-06-04)

    Abstract Different religious leaders are trying to establish a sort of belief in their different minds that their own religion and culture are the best among all. Other existing religious communities and culture are a danger for their own existence. To deal with the afore-mentioned issue, the Buddhist hermeneutic text known as ‘The Guide’ (Nettipakarana), consisting of different types of the Buddha’s teachings, shows that the Buddha’s discourses recorded in the Tipitaka, which were formulated in the light of ‘dialogue’ between the Buddha and ...

    Capacity and Fairness Analysis of Game Theoretic Power Controlled Wireless Access Network 

    Katan Vattanaviboon; Patrachart Komolkiti; Chaodit Aswakul (2013)

    In wireless networks, transmission power has adverse effects. With low transmission power, the received signal may be eclipsed by the noise and interference from other transmitters, resulting in low SINR. On the other hand, with high transmission power, the interference seen at other receivers could be too large, also resulting in low SINR. This paper aims to address this problem by using the game theory. Particularly, the scenario of wireless access network with two transmitters, each with two intended receivers, is considered. Selection of ...
