This paper examines the role of public information communication in dynamic self-enforcing climate agreements. We consider a framework with implicit contracts but also coalition formation context. In stochastic game, where social cost Greenhouse Gasses (GHG) is an unknown random variable, sender, such as Intergovernmental Panel on Climate Change (IPCC), controls release verifiable about state v...

This proposed scheme reversibly embeds data into image predictionerrors by using histogram-pair method with the following four thresholds for optimal performance: embedding threshold, fluctuation threshold, leftand right-histogram shrinking thresholds. The embedding threshold is used to select only those prediction-errors, whose magnitude does not exceed this threshold, for possible reversible ...

In this paper, the e ect of transmitter beam size on the performance of free space optical (FSO) communication has been determined experimentally. Irradiance pro le for varying turbulence strength is obtained using optical turbulence generating (OTG) chamber inside laboratory environment. Based on the results, an optimum beam size is investigated using the semi-analytical method. Moreover, the ...

Decentralized target detection optimisation in multisensor systems, particularly in multisite radar systems, is usually reduced to the optimum choice of detection thresholds at all sensors and of a decision rule at the information fusion centre. For each decision rule, optimum peripheral thresholds are calculated by solving a system of m+1 complicated nonlinear equations in m+1 unknowns where m...

in this paper, a method based on binary-coded genetic algorithm is proposed to explore an optimization method, for obtaining an optimal elliptical tank. this optimization method enhances the rollover threshold of a tank vehicle, especially under partial filling conditions. minimizing the overturning moment imposed on the vehicle due to c.g. height of the liquid load, lateral acceleration and ca...

Increasing environmental concerns are forcing animal industries to reevaluate current feeding practices and their relationships to nutrient excretion. Previous modeling efforts have used simple budgets of nutrient flows through animals, assuming a constant productivity level. This assumption is not valid if animals are not in a steady state. A response model of dairy cow production to levels of...

Spectrum sensing, the problem of detecting the presence of licensed user in the channel is considered in this paper. Energy detection is best suited for the spectrum sensing when prior knowledge about the primary users is unavailable. Existing works report improved versions of energy detection which primarily focuses on maximizing the detection performance. Sensing error minimization is an impo...

In this paper, incorporation of MISO concept is proposed as a solution for increasing energy efficiency and improving BER performance of OFDMCDMA downlink system with pilot tone and threshold detection combining (optimum TDC). The new presented system with MISO included uses spacetime block coding applied to two, three and four transmit antennas. BER (Bit Error Rate) performance in the case of ...

In this paper, a theory of optimaf nonlinear estimation from sampIed data signals where the a posterion probability densities are approximated by Gaussian sums is adapted for application to phase and frequency estimation in high noise. The nonlinear estimators (demodulators) require parallel processing of the received signsf. In the limit as the number of parallel processors becomes infinite th...

This paper compares two types of classifiers applied to bandlimited FSK4 and FSK8 signals. The first classifier employs the decision-theoretic approach and the second classifier is a neural network structure. Key features are extracted using a zero crossing sampler. A novel decision tree is proposed and optimum threshold values are found for the decision theoretic approach. For the neural netwo...
