Machining parameter selection and tolerance specification for raw materials, machine tools and fixtures directly affect product geometric quality and system productivity. However, there currently exists no integrated method for analyzing these variables for machining systems. This paper presents a methodology for simultaneously selecting optimal machining process parameters and tolerance specif...

After attending this presentation, attendees will learn how the Analytical Threshold (AT) has a significant influence on the rates of Type I (i.e. false positives) and Type II (i.e. false negatives) errors. Attendees will be introduced to Receiver Operating Characteristics (ROC) analysis as a method to compare each type of error in order to provide a method to select optimal ATs and disregard s...

A reliable and cost effective system is crucial in satisfying the requirements of users and managers alike. One way to develop such a system is to use existing COTS (Commercial Off-The-Shelf) software products. As an appropriate process model for a software development project, Boehm [2] recommended the use of COTS products in all possible applications. In the US, COTS products are mandated by ...

In general, an optimal model which has the best effect in a specific application among the different estimated models may not necessarily have the same order as the actual model. The objective of the present paper is to propose a criterion for selecting the optimal order model which gives the minimum ARMA spectral estimation error. The model spectral distance (MSD) is proposed to measure the di...

This paper first represent the basic conceptions of anonymous communication, then introduce the fundamentals in Anonymous Communication. Afterwards, we went deep to the classification of anonymous network topological, therefore we could get a better understanding on P2P anonymous communication system. We also systematically analyzes the existing node-select algorithms. Furthermore, we propose a...

There exists an essential diierence between the correct Auto Regressive (AR) model and the optimal AR-model. We try to nd an optimal model balancing between exibility, using many AR-parameters, and low variance, using only a few AR-parameters. We select an optimal AR-parameter con-guration consisting of zero and non-zero parameters given a maximum AR-order. This optimal connguration will be sel...

image completion is one of the subjects in image and video processing which deals with restoration of and filling in damaged regions of images using correct regions. exemplar-based image completion methods give more pleasant results than pixel-based approaches. in this paper, a new algorithm is proposed to find the most suitable patch in order to fill in the damaged parts. this patch selection ...

new product development (npd) is one of the key factors for achieving competitive advantage and maintaining firm growth. therefore, given the importance of this type of projects, this paper is an endeavor to make these projects more successful by effectively managing their risks in the conceptual design phase of new product development. for this purpose, a multi-objective model, with three obje...

Introduction: In Tehran with a population of 9 million currently, about 2.5 million tons municipal solid waste have been producing annually. Materials and Models: In this study by using Life Cycle Assessment (LCA) model an optimal system of waste management of Tehran was recommended. Based on the quantity and quality of waste in Tehran in 2013 and facilities, three scenarios were selected. Fir...

A new optimization method is proposed in this paper for finding the firing angles in multi-level voltage source inverters to eliminate low-order selective harmonics and reduce total harmonic distortion (THD) value of the output voltage. For thid end, Fourier series is used for calculating objective function and selecting specific harmonics. Regarding the nature and complexity of the employed no...
