This paper proposes a new scheduling algorithm named DRRA (Deficit Round Robin Alternated) that achieves an improvement in the uniform distribution of the output traffic respect to the existent DRR (Deficit Round Robin) algorithm. This work is embraced into a line of research that intends to provide Ethernet users with the quality of service of ATM. To achieve this, an architecture called “Cell...

This work is embraced into a line of research that intends to provide Ethernet users with the quality of service of ATM. To achieve this, an architecture called “Cells in Frame” (CIF) is used, which allows ATM cells to be carried in Ethernet frames. This paper proposes a new scheduling algorithm named DRRA (Deficit Round Robin Alternated) that achieves an improvement in the uniform distribution...

Reliable data show that the Nicoyan region of Costa Rica is a hot spot of high longevity. A survival follow-up of 16,300 elderly Costa Ricans estimated a Nicoya death rate ratio (DRR) for males 1990-2011 of 0.80 (0.69-0.93 CI). For a 60-year-old Nicoyan male, the probability of becoming centenarian is seven times that of a Japanese male, and his life expectancy is 2.2 years greater. This Nicoya...

In the research and policy environment, local knowledge (LK) is increasingly seen as an important component of building resilience communities delivering sustainable disaster risk reduction (DRR) approaches tailored to contexts. Many studies focus on documenting LK in different contexts; however, far less emphasis has been given understanding how external stakeholders (i.e. government, NGOs, co...

Large-scale disasters, such as hurricanes, cyclones, tsunamis, and forest fires, have caused considerable damage in recent years. This study investigated two case studies of discontinuous open levees (kasumi-tei), which are a traditional Japanese river technology, on the Matsuura River at sites Okawano Azame-no-se, evaluated advantages these from perspective ecosystem-based disaster risk reduct...

Let X be a compact metric space, let A unital AH-algebra with large matrix sizes, and B stably finite C∗-algebra. Then we give lower bound for the radius of comparison C(X)⊗B prove that dimension-rank ratio satisfies drr(A)=drr(C(X)⊗A). We also class AH-algebras rc(C(X)⊗A)=rc(A). further exact Z-stable C∗-algebras nonzero comparison.

Introduction: Radiation therapy is one of the methods of cancer treatment. In this method, it is necessary to avoid harming the healthy tissues of the patient which is in the vicinity of the target, as much as possible. Treatment verification is one of the most important steps of radiation therapy which has two usual methods, using Port film and EPID. The accuracy and precision of treatment in ...

With the need and adoption of link aggregation where multiple links exist between two adjacent nodes in order to increase transmission capacity between them, there arise the problems of service guarantee and fair sharing of multiple servers. Although a lot of significant work has been done for single-server scheduling disciplines in the past years, not much work is available for multi-server sc...
