CPU scheduling is the basis of multi-programmed operating systems. The main objective of scheduling algorithms is to reduce the response time, waiting time and to increase the throughput and CPU utilization. Round Robin assumes that all processes are equally important; each receives an equal portion (time slice) of the CPU. This will sometimes affect the performance of CPU. This paper considers...

Many applications in wireless sensor networks rely on data from neighboring nodes. However, the effort for developing efficient solutions for sharing data in the neighborhood is often substantial. Therefore, we present a general-purpose algorithm for this task that makes use of the broadcast nature of radio transmission to reduce the number of packets. We have integrated this algorithm into Tin...

A corner detection algorithm proposed by Hood, et al. [6] which detects corner points on a discretely defined curve represented by x, y-coordinates is de-parameterized and its corner detection accuracy is improved. The accuracy of the original algorithm is sensitive to several user-defined parameters. This paper details the process of automated de-parameterization of the algorithm using inverse...

We consider a loosely-coupled algorithm for fluid-structure interaction based on Robin interface condition the fluid problem (explicit Robin-Neumann scheme). study dependence of stability this method parameter in condition. In particular, model we find sufficient conditions instability and method. latter case, relating time discretization parameter, structure densities. Numerical experiments co...

OBJECTIVES This study tests the robustness of the relationships between primary care, income inequality, and population health by (1) assessing the relationship during 4 time periods-1980, 1985, 1990 and 1995; (2) examining the independent effect of components of the primary care physician supply; (3) using 2 different measures of income inequality (Robin Hood index and Gini coefficient); and (...

509 Abstract—Algorithms used for scheduling play a major role in providing quality of service in video streaming. This paper describes a simulation environment that has been designed combining network simulator ns2 with video codec to predict the quality of service. Virtual clock scheduling algorithm has been applied to evaluate the performance metrics and compared with the weighted round robin...

BACKGROUND Sleeping metabolic rate (SMR) is used as a proxy for basal metabolic rate in infants, when measurement while awake is not practical. Measuring SMR via indirect calorimetry (IC) can be useful for assessing feeding adequacy especially in compromised neonates. Standard IC equipment, including a hood placed over the head, is not designed for the smallest of patients. Our aim was to deter...

A high-order Galerkin Least-Squares (GLS) finite element discretization is combined with massively parallel implicit solvers. The stabilization parameter of the GLS discretization is modified to improve the resolution characteristics and the condition number for the high-order interpolation. The Balancing Domain Decomposition by Constraints (BDDC) algorithm is applied to the linear systems aris...

In this work we propose a Robin-Robin preconditioner combined with Krylov iterations for the solution of the interface system arising in fluid-structure interaction (FSI) problems. It can be seen as a partitioned FSI procedure and in this respect it generalizes the ideas introduced in [Badia, Nobile and Vergara, J. Comput. Phys. 227 (2008) 7027 –7051]. We analyze the convergence of GMRES iterat...
