This document is meant to help individuals use the Cerebral Signal Phase Analysis toolbox which implements different methods for estimating the instantaneous phase and frequency of a signal and calculating some related popular quantities. The toolbox – which is distributed under the terms of the GNU GENERAL PUBLIC LICENSE as a set of MATLAB R © routines – can be downloaded at the address http:/...

This paper describes a two-phase simulation-based optimisation procedure that integrates the Genetic Algorithm and Response Surface-based Linear Search algorithm for developing optimal power-of-two replenishment policy in multi-echelon environment during the maturity phase of the life cycle of a product. The problem involves a search in high dimensional space with different ranges for decision ...

We present a dynamic network model for modeling two-phase flow. We account for wetting layer flow, meniscus oscillation, and the dynamics of snapoff. Interfaces are tracked through pore elements using a modified Poiseuille equation for the equivalent hydraulic resistance of the fluids between the pore element centers. The model is used to investigate the effects of capillary number and viscosit...

We investigate the dynamics of large arrays of coupled phase oscillators driven by random intrinsic frequencies under a variety of coupling schemes, by computing the time-dependent cross-correlation function numerically for a two-dimensional array consisting of 128 X 128 oscillators as well as analytically for a simpler model. Our analysis shows that for overall equal interaction strength, a sp...

Collaborative filtering (CF) is the most widely used and successful approach for personalized service recommendations. Among the collaborative recommendation approaches, neighborhood based approaches enjoy a huge amount of popularity, due to their simplicity, justifiability, efficiency and stability. Neighborhood based collaborative filtering approach finds K nearest neighbors to an active user...

This work investigates the effect of the explicit inclusion of queueing delays due to locking overhead in a performance study of a two phase locking concurrency control method. A mean value analysis is used to calculate the system's performance measures, response time and throughput. It is found that the locking overhead's contribution to delay depends largely on the degree of page faulting act...

The use of a phase plate in electron microscopy has shown renewed interest, triggered by a publication on this topic in 2001 by Danev and Nagayama [1]. This interest can be understood from the fact that many samples that are studied in TEM are weak phase objects. The use of a phase plate is the obvious method of choice to convert otherwise invisible phase modulations into visible amplitude modu...

Routing in computer networks has played a special role in recent years. The cause of this is the role of routing in a performance of the networks. The quality of service and security is one of the most important challenges in routing due to lack of reliable methods. Routers use routing algorithms to find the best route to a particular destination. When talking about the best path, we consider p...
