This study investigates spatial water quality assessment of selected river basins in the three different states in Malaysia. Environmetric techniques namely, cluster analysis (CA), principal component analysis (PCA), and discriminant analysis (DA), were applied to study the spatial variations of the most significant water quality variables in order to determine the origin of pollution sources ...
In recent years, multibaseline phase unwrapping (MBPU) has been widely studied, but it is still suffering from the problem of low noise robustness. view this, two cluster correction methods for cluster-analysis (CA)-based MBPU algorithms are presented to improve accuracy and effectiveness algorithm. first method, a suitable box centered on each pixel selected with highest frequency in taken as ...
Calcium-binding protein 1 (CaBP1) is a neuron-specific member of the calmodulin superfamily that regulates several Ca(2+) channels, including inositol 1,4,5-trisphosphate receptors (InsP3Rs). CaBP1 alone does not affect InsP3R activity, but it inhibits InsP3-evoked Ca(2+) release by slowing the rate of InsP3R opening. The inhibition is enhanced by Ca(2+) binding to both the InsP3R and CaBP1. Ca...
Changes in consumer behavior and the complexity of organizational decision-making, environmental regulations, policies are bases for transforming manufacturing processes to reduce usage natural resources impact. Traditional management methods limit corporate performance assessment. The study aims analyze 349 organizations terms their water, energy, hazardous non-hazardous waste. A descriptive c...
ABSTRACT G1, also known as Mayall II, is one of the most massive star clusters in M31. Its mass, ellipticity, and location outer halo make it a compelling candidate for former nuclear cluster. This paper presents an integrated light abundance analysis based on moderately high-resolution (R = 15 000) spectrum obtained with spectrograph Hobby–Eberly Telescope 2007 2008. To independently determine...
In this paper we describe our study on the characterization of cigarette samples according to their mineral content. Acid digestion assisted by microwaves was employed, and inductively coupled plasma optical emission spectrometry was the analytical technique used for the determination of Al, Ba, Ca, Cu, Fe, K, Mg, Mn, Na, P and Sr in conventional, light, and flavorized cigarettes. Multivariate ...
We implemented four basic cellular automata (CA) algorithms on a Beowulf cluster with 8 processors. The CA algorithms are, namely, (1) Game of Life, (2) GreenburgHasting, (3) Cyclic Space, and (4) Hodgepodge Machine.
In this paper an application of the cluster analysis technique in educational planning is demonstrated by means of a developed computer software with some characteristics of an expert system. The main idea is based on the knowledge-based systems which have been applied in group technology. The software is applied to weekly schedules of the courses and professors of the Industrial Engineering De...
Clusters are geographically close groups of related companies or institutions related to a certain area which are inherently more efficient than the other companies due to advantages such as being located in one place, networks, external knowledge, variability of human capital, etc. Today, development through clusters plays a pivotal role in the economic and industrial policies of developed...
this research has been taken among the students of high school in karaj city during the years 1391 and 1392. this is a survey research and data gathering is through questionnaires. studying the “an analysis of students’ tendency toward non-native reference groups in karaj”. the questionnaire was distributed among 260 of these students who were chosen through multi step cluster sampling. conside...
