Based on the analysis of active queue management （AQM） of DiffServ network, we propose a resource management scheme, which allows borrowing resources from unused reservation, accord- ing to the characteristics and advantages of cognitive networks. First, some nodes reserve certain proportion capacity for some special services （for instance, some services pay additional money） to guarantee the priority of these applications. Then resources are assigned according to the different parameters of services. If the available resource can not meet the requirements of new services, real- time ones are admitted with higher priority and allow borrowing the unused reservation from other nodes appropriately. Simulations show that, the proposed scheme has good performance at network resource utilization, the admission rate of new aDolications and OoS of users.展开更多

This paper considers optimizing the utilization of spectrum resource in heterogeneous environment consisting two different networks： wireless local area network （WLAN） and time division-synchronous code division multiple access （TD-SCDMA） network. An optimal joint spectrum borrowing scheme maximizing overall network revenue is proposed with quality of service （QoS） constraints over both the WLAN and the TD-SCDMA cellular networks. Simulation results illustrate that system revenue earned in the proposed joint spectrum borrowing scheme is significantly larger than the case when individual networks are optimized independently.展开更多

Public savings as a financial option take up an important place in the scope of expressed government budget balances related to public borrowing requirements which are increasingly located together with budget deficits. This fact especially is pertaining to investments and capital’s transfers that are subject to the public decision making process towards economic growth in the future in developing countries like Turkey. Therefore, increasing public savings’ limits appear on these countries as an inevitable financial phenomenon concerning the desired investments. Turkey, as a developing country, has faced two financial phenomenons that increase borrowing requirement terms that lead to intend financial balances that have generally deviated after 2009 financial crisis. Firstly, it’s increasing foreign debt burden and the public savings’ levels that have not been enough to cover all the proportion of foreign debt payments since 2009. Secondly, the effect level of global crisis on the exchange rates directly causes the deviation of national currency values as a meaningful important negative impact on budget balances that are aimed at together with the macroeconomic financial balances.展开更多

The bank pays at an interest rate r for any deposit, and takes at a larger rate r′ for any loan. As in the paper of Xu Wensheng and Chen Shuping in JAMS(B), where an analogous problem in finite horizon is studied, optimal strategies are obtained via Hamilton Jacobi Bellman (HJB) equation which is derived from dynamic programming principle. For the specific HARA case, i.e. U(t,c)=e -βt c 1-R 1-R , this paper gets the optimal consumption and optimal investment in the form ofc * t=β-Rw t\ and \ π * t=b-γRσ 2w twith γ:= max{ r, min{ r′,b-Rσ 2 }}, =(1-R)γ+(b-γ) 22Rσ 2]. This result coincides with the classical one under condition r′≡r.展开更多

Based on the theory proposed, the principles and the regulations of the DRD for making operation units of multi-valued operation with carrying/borrowing free are also presented. The research work has come to the following important conclusion： let D be a special state contained in n physical informative states, then one may figure out any multi-valued processors within n^（n×n） carrying/borrowing free n-valued units by the composition some of n×n×（n-1） simplest basic operating units according to the regulations of DRD proposed in this paper. The detailed systematic way of our design regulations is highlighted step by step in the paper with an example of design of a tri-valued logic optical operating unit. The real architecture, the procedure, and the experimental results of our sample in tri-valued logic operating unit are given. Finally, a re-constructible model of ternary logical optical processor is introduced. The theory proposed in the paper has laid down a solid foundation for the design of re-constructible carrying/borrowing free operating units in ternary optical computers and can be widely used as the designing reference in a variety of multi-valued logic operating units.展开更多
