Objectives: Monitoring development in infancy results in early detection of developmental delay, and early intervention can prevent sever complications of developmental disorders. The purpose of this study was to determine quality of developmental screening of 3-12 months infants referred to Tehran Health Centers, through comparing with screening by Bayley Infant Neurodevelopmental Screener II ...

In this paper we present a new accurate steganalysis method for the LSBreplacement steganography. The suggested method is based on the changes that occur in thehistogram of an image after the embedding of data. Every pair of neighboring bins of ahistogram are either inter-related or unrelated depending on whether embedding of a bit ofdata in the image could affect both bins or not. We show that...

A Monte Carlo method was developed to simulate multicomponent aerosol dynamics, specifically with simultaneous coagulation and fast condensation where the sectional method suffers from numerical diffusion. This method captures both composition and size distributions of the aerosols. In other words, the composition distribution can be obtained as a function of particle size. In this method, part...

We study the following load balancing problem on paths (PB). There is a path containing n vertices. Every vertex i has an initial load hi, and every edge (j, j + 1) has an initial load wj that it needs to distribute among the two vertices that are its endpoints. The goal is to distribute the load of the edges over the vertices in a way that will make the loads of the vertices as balanced as pos...

This paper describes the use of histogram modification functions to improve the retrieval efficiency of the content-based image retrieval system based on bins approach. Four different functions explored in this paper used as histogram specification to modify the histograms are; histogram equalization (EQH), polynomial function (POLY), linear equations (LinearEQ1,2,3) and logarithmic function (L...

We demonstrate that a proper control sample correlates linearly with the background parts of its corresponding ChIP sample. In the following examples, we first draw the original ChIP vs control bins counts to show the over-abundance of high ChIP count bins due to binding signals. Then we filter the strong binding signals by calling peaks with SPP (Kharchenko et al., 2008) at FDR 0.1 level and e...

Given a set of n items with weights wi, i = 1, . . . , n, the bin packing (BP) problem consists of finding the minimum number of bins of capacity C necessary to pack the items, without violating the capacity constraint. This formulation also entails another problem (DBP), in which we seek to minimize the capacity of a fixed number m of identical bins, so that all items fit in the m bins without...

Recent research suggests decentralised probabilistic protocols on support for multipeer communication. The protocols scale well and impose an even load on the system. They provide statistical guarantees for the reliability, i.e. an information sent from an arbitrary source will reach all its destinations. Analysing the reliability is based on modelling the propagation of events as an epidemic p...

We analyze the approximation behavior of some of the best-known polynomial-time approximation algorithms for bin-packing under an approximation criterion, called differential ratio, informally the ratio (n − λ(I))/(n − β(I)), where n is the size of the input list, λ(I) is the size of the solution provided by an approximation algorithm and β(I) is the size of the optimal one. This measure has or...
