Coopetition Games and Its Application in Cournot Model

Coopetition has become the current strategic trend of the economic development. In this paper, coopetition game and the equi‘ibrium have been developed through comparing the characteristics of cooperation game with those of competition game. Furthmore, an algorithm using one kind of minimax theorem proposed by Dingzhu-Du in 1990 is put forward to solve coopetitior game. The algorithm has great advantages over other methods, which can solve irregular and non-differential concave or convex function of the games.A coopetition game of cournot model with asymmetric oligarchs is advanced and the coopetition equilibriums have been obtained by simulation. The simulation results are compared with that of Nash equilibrium. Conclusions can be made that more members in a coalition could get higher satisfaction degrees at coopetition equilibriums, which is dependent on cost and potential market demands.     

Multiple QoS modeling and algorithm in computational grid

Multiple QoS modeling and algorithm in grid system is considered. Grid QoS requirements can be formulated as a utility function for each task as a weighted sum of its each dimensional QoS utility functions. Multiple QoS constraint resource scheduling optimization in computational grid is distributed to two subproblems: optimization of grid user and grid resource provider. Grid QoS scheduling can be achieved by solving sub problems via an iterative algorithm.     

Common Persistence and Error-Correction Mode in Conditional Variance

1　 IntroductionThe persistence of GARCH model implies that the shocks of the current conditionalvariance remain persistent effects for the conditional variances of all future horizons,i.e.the current conditional variance would never be equal to zero as time is infinite.Theconception of persistence existing in the autoregressive conditional heteroscedasticityprocess was firstly introduced by Engle and Bollerslev ( 1 986) .They studied theintegration GARCH model or IGARCH model and analy…

The Fundamental Definitions in Radar Measurement Principle and Theory of Space and Time

Fundamental definitions of distance and velocity in radar measurement principle are examined and revised from strict theoretical point of view. Synchronization scheme - for clocks in uniform, translatory relative motion is introduced as theoretical foundation for GPS and GLONASS type navigation and positioning technology. Traditional definitions of two-way radar measurement, based on arithmetic mean vlaue concept, turn out to be special cases of revised definitions for one-way radar measurement, based on geometric mean concept, derived from synchronization of moving clocks in accordance with the principle of relativity. The essential physical meaning of Lorentz transformation is interpreted in terms of radar measured parameters. Invariance or absoluteness of four dimensional interval turns out to be invariance or absoluteness of geometric mean time interval. The Lorentz factor turns out to be ratio of geometric mean and arithmetic mean time intervals in terms of radar measured parameters. Theoretical re     

Applications of Atomic and Molecular Theory to Calculations in Space Science and Engineering

A systematic elaboration is given on atomic and molecular theory problems encountered in dealing with space science and engineering. Three sections are presented in the paper on calculations for gas thermodynamic and transfer properties, characteristics of the optical radiation from the reentry' bodies, and the interaction between surfaces of man-made satellites and incident particles. Researches on them are much related to the fundamental problems regarding the atomic and molecular theory.     

Platform Competition for Advertisers and Viewers in Media Markets with Endogenous Content and Advertising

In this paper,we investigate two competing pay-tv platforms or free-to-air media platforms that consist of two groups of agents:viewers and advertisers.The pay-tv platforms can receive revenues from charging viewers pay-per-view prices and advertising,while the free-to-air platforms can only obtain all incomes from advertising.We discuss and compare advertising intensities and program content provisions of the two competing media platforms.Our findings show that if the extent to which viewers dislike advertising(the nuisance for advertising)is more massive than the marginal benefit that advertisers receive from an additional viewer,the pay-tv stations tend to maximally differentiate their program content and charge the viewers higher pay-per-view prices.If the nuisance approaches to the marginal benefit,however,both stations should offer similar program content,and charge the viewers lower prices under certain conditions.Particularly,if both platforms provide duplicated content,they should subsidize the viewers.In contrast,we show that the free-to-air media platforms never duplicate program content with a positive nuisance for advertising,and tend to offer maximal differentiated content if the nuisance is sufficiently large.Moreover,we reveal that if the viewers greatly dislike advertising(care less about advertising),the advertising volume of the pay-tv platforms is lower(higher)than that of the free-to-air platforms.Finally,we extend our base model to the case in which a pay-tv platform competes against a free-to-air station,and numerically show that the profit of the pay-tv platform may be larger or smaller than that of the free-to-air station.

Empirical data decomposition and its applications in image compression

A nonlinear data analysis algorithm, namely empirical data decomposition (EDD) is proposed, which can perform adaptive analysis of observed data. Analysis filter, which is not a linear constant coefficient filter, is automatically determined by observed data, and is able to implement multi-resolution analysis as wavelet transform. The algorithm is suitable for analyzing non-stationary data and can effectively wipe off the relevance of observed data. Then through discussing the applications of EDD in image compression, the paper presents a 2-dimension data decomposition framework and makes some modifications of contexts used by Embedded Block Coding with Optimized Truncation EBCOT . Simulation results show that EDD is more suitable for non-stationary image data compression.     

Channel Mismatching in Sidelobe Canceler: Limitations and Remedies

After a brief recall of the Sidelobe Canceler (SLC) working principle, including the derivation of a general formula for the Cancellation Ratio (CR), the effects of channel mismatching are investigated. In particular, curves providing CRvalues as a function of amplitude and phase channel mismatching, radar bandwidth, and jammer direction of arrival (JDOA) are provided for the cases of one and two auxiliary antennas. Subsequently, a time -space processor for performance restoration is analyzed in detail. In addition to the above mentioned quantities, the attainable CR value is expressed as a function of the space-time processor parameters. The contribution of the paper is related to the derivation of a number of mathematical equations of CR for several cases of practical interest for the radar engineer. In addition, several curves are presented to assist design of SLC systems.
