In this paper we present a new model for calculating the capacitance of MEMS sensor with corrugated diaphragm. In this work the effect of residual stress is considered on deflection of diaphragm and capacitance of sensor. First, a new analytical analyzes have been carried out to derive mathematic expressions for central deflection of corrugated diaphragm and its relationship with residual stres...

In this paper we treat a general form of location model. It is typically assumed that the error term is distributed according to the law belonging to the class of elliptically contoured distribution. Some sorts of shrinkage estimators of location and scale parameters are proposed and their exact bias and MSE expressions are derived. The performance of the estimators under study are compl...

Monte Carlo simulations of a system consisting of a ferromagnetic layer exchange coupled to a diluted antiferromagnetic layer described by a classical spin model show a strong dependence of the exchange bias on the degree of dilution in agreement with recent experimental observations on Co/CoO bilayers. These simulations reveal that diluting the antiferromagnet leads to the formation of domains...

Background: The link between food insecurity and weight disorders of children or adolescents remains controversial. Therefore, this systematic review and meta-analysis aimed to clarify the association between food insecurity and weight disorders of children and adolescents in Iran. Methods: PubMed, ISI Web of Science, Scopus, Google Scholar, Magiran, and SID databases were searched up to August...

ITEM BIAS: MANTEL-HAEHSZEL AND THE RASCH MODEL John M. Linacre and Benjamin D. Wright Memorandum No. 39 MESA Psychometric Laboratory Department of Education University of Chicago February 1987 The Mantel-Haenszel (MH) procedure attempts to identify and quantify differential item performance (item bias). This paper summarizes the MH statistics, and identifies the parameters they estimate . An eq...

We present a new model for the general study of how the truth and biases affect human judgment. In the truth and bias model, judgments about the world are pulled by 2 primary forces, the truth force and the bias force, and these 2 forces are interrelated. The truth and bias model differentiates force and value, where the force is the strength of the attraction and the value is the location towa...
