A class of extensions of Small Nim are investigated. Under normal or misére play convention, all P-positions are determined. The structures of P-positions are of algebraic form, which permits to decide in polynomial time whether or not a given game position is a P-position.
Terahertz waves bound inside a metallic rod-array is successfully demonstrated and used to sense ultra-thin molecular layers in the presentation. From the transmitted surface waves with constructive interference, nanometer-thick films of SiO2 and ZnO are successfully identified, corresponding to λ/1923 and superior to the available THz sensors.
Web services (WSs) can cooperate with each other to provide more valuable WSs. Current approaches for WS cooperation have typically assumed that WSs are always willing to participate in some form of cooperation, and have undermined the fact that WSs are autonomous in this open environment. This assumption, however, becomes more problematic in community-based WS cooperation due to the dynamic nature...
A few of works have recently focused on relieving service users of the role played in assigning numeric values to QoS criteria as required in traditional service selection scheme. Towards such goals, skyline services for example have been studied recently by a lot of researchers. However, the size of skyline services sometimes is not easily controlled due to intrinsic attributes of services. Besides,...
This article puts forward a novel idea of power tower inspection depending on model-based behavior planning. It mainly focuses on the problems caused by uncertain security, flight time limitation and stochastic noise affection when inspecting with flying robot. Firstly, we construct a safety space and some target viewing regions based on the model of the power tower. Then a reinforcement learning...
A.S. Fraenkel introduces a new (s, t)-Wythoff's game which is the generalization of both a-Wythoff's game and Wythoff's game. Fraenkel determines all P-positions of (s, t)-Wythoff's game under normal play convention. In this paper, the (s, t)-Wythoff's game under the misere play convention is investigated. Both the set of all P-positions and optimal strategies are given. Our results also provide answers...
A.S. Fraenkel introduces a new a-Wythoff's game which is the generalization of Wythoff's game. Fraenkel determines all P-positions of a-Wythoff's game under normal play convention. In this paper, we introduce two new restricted versions of a-Wythoff's game, Odd-Even Wythoff's Game and Odd-Even a-Wythoff's Game. Both new games are investigated. All its P-positions under normal play convention are given,...
Reputation is useful for establishing trust between Web service (WS) providers and WS consumers. In the context of WS composition, a challenging issue of reputation management is to propagate a user's impression of a composite WS (i.e., the user's feedback rating) to its component WSs. In this paper, we propose a Shapley value based approach which can achieve fair impression propagation, that is,...
A plastic ribbon integrated with one-dimensional-metal grating is first demonstrated as a hybrid-plasmonic waveguide to highly confine terahertz radiation approaching to power range of λ/26 and the longest propagation distance is experimentally up to 50mm.
