Caching has been used for decades as an effective performance enhancing technique in computer systems, among others. However, the traditional cache replacement algorithms are not easily applicable to WWW applications. Moreover, the frequently used hit-ratio and byte-hit ratio are not appropriate measures in WWW applications, because non-uniformity of the object sizes and non-uniformity cost of ...

Financial derivatives are contracts concerning rights and obligations to engage in future transactions on some underlying financial instrument. A major concern in financial markets is to compute an expected value of such contracts as a basis for trading decisions. The Cox, Ross and Rubinstein (CRR) binomial tree model is a popular discrete approach to such computations, which requires time quad...

INTRODUCTION Segmental ostial pulmonary vein isolation (PVI) is considered a potentially curative therapeutic approach in the treatment of paroxysmal atrial fibrillation (PAF). There is only limited data available on the long-term effect of this procedure. METHODS Patients (Pts) underwent a regular clinical follow up visit at 3, 6 and 24 months after PVI. Clinical success was classified as co...

We present a case study of liquefaction triggering analysis performed in the Nakdong-river delta region, based on shear wave velocities obtained by Microtremor Array Method and ground motions generated broadband hybrid motion simulation. Assuming M<sub>w</sub>6.2 earthquake occuring at Dongrae fault, studied sites exceeded design spectra provided Korean Design Standard many exhibite...

Energy usage has been an important concern in recent research on online scheduling. In this paper we study the tradeoff between flow time and energy [1,5,7,19] in the multi-processor setting. Our main result is an enhanced analysis of a simple non-migratory online algorithm called CRR (classified round robin) on m ≥ 2 processors, showing that its flow time plus energy is within O(1) times of th...

During fasting, activation of the counter-regulatory response (CRR) prevents hypoglycemia. A major effector arm is the autonomic nervous system that controls epinephrine release from adrenal chromaffin cells and, consequently, hepatic glucose production. However, whether modulation of autonomic function determines the relative strength of the CRR, and thus the ability to withstand food deprivat...

The centromere of eukaryotic chromosomes is essential for the faithful segregation and inheritance of genetic information. In the majority of eukaryotic species, centromeres are associated with highly repetitive DNA, and as a consequence, the boundary for a functional centromere is difficult to define. In this study, we demonstrate that the centers of rice centromeres are occupied by a 155-bp s...

Over the past years researchers at Aalborg University have been developing a method for examining change readiness of hospital staff during the implementation of new IT-systems. (CRR; Change readiness-research). The aim is to provide the hospital-management with a tool that will lead to an optimal implementation of new IT-systems. The method has recently been used in department Y at Skejby Hosp...

CCAM is an access method for general networks. It uses connectivity clustering. The nodes of the network are assigned to disk pages via the graph partitioning approach to maximize the CRR, i.e., the chances that a pair of connected nodes are allocated to a common page of the le. CCAM supports the operations of insert, delete, create, and nd as well as the new operations, get-A-successor and get...

This paper proposes a group of picture (GOP)-aware multipath source routing protocol (GMSR) for real-time moving picture experts group (MPEG) video delivery in mobile ad hoc networks (MANETs). First, as existing multipath routing protocols usually produce large amount of route reply packets in a short period of time, which may cause traffic congestion, a cumulative route reply strategy (CRR) is...
