In general, optimal allocations for Series-Parallel redundant configurations being carried out using unit or component redundancies. However, Dynamic programming approach by which the optimal allocation can be used when the values of reliabilities and cost for each component are known. The advantage of Dynamic programming approach is that it is simple and it requires less processing time. In th...
Cognitive Radio (CR) is an emerging technology for future wireless communication and technology. In the existing system, there is a multiple allocation over all the bands and also there is a crisis for spectrum availability, therefore a new approach for spectrum licensing is needed. Hence the optimal solution for the above case is cognitive radio. the resource-allocation problem in multihop CR ...
Elevated atmospheric CO2 concentration (eCO2) has the potential to increase vegetation carbon storage if increased net primary production causes increased long-lived biomass. Model predictions of eCO2 effects on vegetation carbon storage depend on how allocation and turnover processes are represented. We used data from two temperate forest free-air CO2 enrichment (FACE) experiments to evaluate ...
We review approaches to predicting carbon and nitrogen allocation in forest models in terms of their underlying assumptions and their resulting strengths and limitations. Empirical and allometric methods are easily developed and computationally efficient, but lack the power of evolution-based approaches to explain and predict multifaceted effects of environmental variability and climate change....
This paper examines the problem of congestion control evaluation in dynamic networks. We determine a source of deficiencies for existing metrics of congestion control performance – the existing metrics are defined with respect to ideal allocations that do not represent short-term efficiency and fairness of network usage in dynamic environments. We introduce the concept of an effair allocation, ...
in the market for factors of production usually the equilibrium will be stablished on the based of the equality between the value of marginal products of output and their relative price level. on the other hand the value of marginal product of output is a function of observed rate productivity of output and the market capacity of factors of production. thus the fluctuation in the rate of produc...
abstract tax is one of the main sources of financing government budget. therefore, having a clear picture about the attainable amount of taxes are not only necessary for optimal allocation of scarce resources for tax collection, but also helps the government to develop precise tax collection programs .in this article, the structural features of the tax revenues series have first been examined i...
