In this paper, a stochastic cell formation problem is studied using queuing theory framework and considering reliability. Since cell formation problem is NP-Hard, two algorithms based on genetic and modified particle swarm optimization (MPSO) algorithms are developed to solve the problem. For generating initial solutions in these algorithms, a new heuristic method is developed, which always cre...

This study focuses on the ability of commercial natural bath sponges, which are made from skeletons marine to sorb Hg waters. The main component these sponges is spongin, a protein-based material, closely related collagen, offering plenitude reactive sites great variety amino acids in protein chains, where ions can sorb. For dose 40 mg L−1 and initial concentration 50 μg Hg(II), spongin (MS) re...

In many structural applications, concretes reinforced with short metal or synthetic fibers (fiber-reinforced concrete (FRC)) have a number of advantages over traditional steel rebars reinforcement, such as easier and more economical production, wear resistance, impact integrity, etc. the present study, several mixes were developed prismatic FRC specimens fabricated. Their behaviors studied usin...

Results in one field necessarily give insight into the others, and all have much potential for scientific and technological application. The Hadamard-transform technique once been applied to the spectrometry also has its use in the SNR Enhancement of OTDR. In this report, a new set of code (Simplex-codes) is discussed and where the addition gain of SNR come from is implied. Keywords—Hadamard-tr...

To build a Cooperative Information System from several pre-existing heterogeneous systems, the schemas of these systems must be integrated. Operations used for this purpose include conforming operations, which change the form of a schema. In this paper, a set of primitive conforming operations for Object-Oriented schemas are presented. These operations are organized in matrixes according to the...

Snow cover phenology has exhibited dramatic changes in the past decades. However, distribution and attribution of hemispheric scale snow anomalies remain unclear. Using satellite-retrieved products, ground observations, reanalysis climate variables, this study explored onset date, end duration days over Northern Hemisphere from 2001 to 2020. The latitudinal altitudinal distributions 20-year ave...

This Application Note describes both HPLC and UHPLC methods to simultaneously separate and identify seven tannin compounds as aging markers in barrel-aged alcoholic beverages. The proposed methodology was applied to four different matrixes: whisky, brandy, rum, and tequila, to demonstrate a correlation between aging time and total tannin concentration level. Such a methodology could easily lead...

Throughout, we will only look at simple linear regression. The formulas are easier to understand, and the intuition is entirely the same. (The formulas are the same too, just reinterpreting X as vectors or matrixes as appropriate.) Also, just like in class we will do everything conditional on X. That means we will treat the values X1, X2, . . . , Xn as fixed numbers; they are not random. This d...

Fipronil is a current use pesticide, widely used in many crops, commonly adsorbed to sediments of aquatic environments. The purpose this study was evaluate the biomarker responses and fipronil distribution pattern different matrixes (fish, sediment water) after juveniles P. lineatus exposure at two environmental concentrations (5.5 82 ?g kg ? ?1 ) fipronil-spiked sediments. levels oxidized prot...
