The current study aims at modelling the dispersion of two pollutants, namely CO (carbon monoxide) and SO2 (sulfur dioxide) released from District 7 of Tehran Municiaplity, from 20 main line sources, by means of CALPUFF modeling system. CALPUFF is a non-steady state puff modeling software which employs meteorological, terrain, and land-use data to effectively simulate air pollutants' dispersion ...

The following paper deals with the estimation of partial parameters for non stationary sinusoids. First the existing bias for the analysis of non stationary sinusoids in a standard estimator is discussed. Then a new approach to bias reduction is proposed that consists of frequency slope estimation and demodulation to reduce the bias of the standard parameter estimator. The new approach does not...

This paper compares the standard, naive method of computing all distinct longest common subsequences, or of computing all LCS embeddings, to more efficient methods with running time comparable to the output size. Included in this analysis is a determination of the maximum possible number of LCS embeddings in two input sequences, as a function of the total number of input characters. Also includ...

— Using Sen’s capability approach, we propose to measure two components of wellbeing—standard of living and quality of life. Unlike the UNDP Human Development Index, the two indices do not mix measures of resource availability and of functioning and capability. The empirical results for 170 countries are based on two multidimensional analyses, the Totally Fuzzy Analysis and the Factorial Analys...

background: obesity is a major risk factor for chronic diseases and has a role on high blood pressure, diabetes type ii, etc., this review assesses the prevalence of iranian children obesity and overweight for different age categories and compares the three standard definitions of obesity. materials and methods: to retrieve desirable studies concerning childhood anthropometric data from differe...

This paper compares the worst case performance of eight standard sorting algorithms It investigates how well suited these algorithms are for hard real time sys

This paper proposes a novel algorithm called the sparse Hough transform, which is shown to have better performances than the standard Hough transform for sparse input data collected from a laser on a mobile robot. In the context of laser sensing and perception for autonomous ground robots, this paper studies performances of the sparse Hough transform and compares it with other segmentation and ...

—The International Organización for Standardization has decided to develop a new metadata standard for learning resources. This standard claims to enhance the compatibility, flexibility and focus on the user requirements. This article presents the new ISO/IEC MLR standard, describes it and compares the MLR data elements to those defined in Dublin Core and in LOM.
