Upper and lower bounds are studied for the solutions of Markov renewal equations. Some of their special cases are derived under specific marginal conditons and in an alternating environment. The method to construct the bounds is also explained in detail. At the end, these bounds are applied to a...

Gompertz functions have been widely used in characterizing biological growth curves. In this paper we consider D-optimal designs for Gompertz regression models. For homoscedastic Gompertz regression models with two or three parameters, we prove that D-optimal designs are minimally supported....

This work presents simulations and experimental measurements of two negative refraction metamaterial samples at microwave frequencies. The two samples are composed of Four-Triangle Split Resonant Rings and Metal Wires (FTSRRs–MWs) with different cell sizes which are found to play an important...

We conduct analysis on the urban construction's demand for land, tourism's demand for land, infant industry's demand for land and infrastructure's demand for land in Hainan Province, respectively, and forecast the amount of newly-added land in Hainan Province in 2015 compared to 2008. Based on...

We develop a new genetic algorithm to solve an integrated Equipment-Workforce-Service Planning problem, which features extremely large scales and complex constraints. Compared with the canonical genetic algorithm, the new algorithm is innovative in four respects: (1) The new algorithm addresses...

We analyze the effects of a merger between two competitors in a Bertrand-Edgeworth model. The merger has no effect on equilibrium prices if a pure strategy equilibrium prevails both before and after the merger. Otherwise, the merger leads to higher prices. In the case where a mixed strategy...

Exploitation of natural gas hydrate is expecting to be an important strategic way to solve the problem of energy depletion. Understanding the effectiveness of the well configuration plays a pivotal role in gas production from the hydrate reservoir. This study evaluates the methane hydrate...
