This paper addresses the problem of resource fragmentation (RF) in QoS controlled networks. Resources are said to be fragmented when they are available in non-contiguous blocks and hence cannot be utilized by incoming calls with high resource demands. This paper shows the effect of resource fragmentation on QoS controlled networks and presents the Dynamic Resource Redistribution (DRR) algorithm...

O wning Natural resources has been beneficial for some Countries, but hurtful for some others. Optimum management of natural resources in the former group has enhanced economic growth, bad governance, however, has led to Dutch Disease in the latter group. Bad governance in Iran has created Dutch Disease, Rentier State, and Resource Curse, DRR as a characteristic triangle. As the Iran...

under the smart grid environments, demand response resources (drrs) as power system resources can effectively participate in and improve performance of electric systems. congestion management is one of the technical challenges in which drrs can play a significant role. previously, congestion management is applied without considering the power system uncertainties. therefore, a stochastic conges...

Dietary restriction (DR) results in a robust increase in lifespan while maintaining the physiology of much younger animals in a wide range of species. Here, we examine the role of drr-2, a DR-responsive gene recently identified, in determining the longevity of Caenorhabditis elegans. Inhibition of drr-2 has been shown to increase longevity. However, the molecular mechanisms by which drr-2 influ...

THE CONSULTANT PHARMACIST JUNE 2003 VOL. 18, NO. 6 Although it has been a core component of consultant pharmacy practice for more than 30 years, drug regimen review (DRR) continues to evolve to accommodate many new additions to the increasingly complex medication armamentarium, and the changing needs of long-term care patient populations. In the first article in this three-part series, we explo...

In this thesis, we consider resource allocation schemes for infrastructure-based multipoint-topoint wireless networks like IEEE 802.16 networks and infrastructure-less ad-hoc networks. In the multipoint-to-point networks, we propose channel and Transport layer aware uplink scheduling schemes for both real-time and best effort services, whereas in ad-hoc networks, we propose channel aware conges...

Three fast scheduling algorithms are proposed to handle efficiently polarized traffic in an advanced architecture for multiple-server optical IP packet routers. These schedulers must be capable of transferring several fixed-sized packets per port per time slot rather than one cell per time slot. An optical burst packet (OBP) contains a number of cells, obtained either from a network protocol or...

In the emerging high-speed packet-switched networks, fair packet scheduling algorithms in switches and routers will form an important component of the mechanisms that seek to satisfy the Quality of Service (QoS) requirements of various applications. The latency bound of a scheduling discipline is an important QoS parameter, especially for real-time playback applications. Frame-based schedulers ...

Reward-risk ratio (RR) is a very important stock market definition. In order to capture the situation that the investor does not have complete information on the distribution of the underlying uncertainty, people extend RR model to distributionally robust reward-risk ratio (DRR) model. In this paper, we study the DRR problem where the ambiguity on the distributions is defined through Wassertein...
