determination of maximal singularity free zones in the workspace of parallel manipulator
due to the limiting workspace of parallel manipulator and regarding to finding the trajectory planning of singularity free at workspace is difficult, so finding a best solution that can develop a technique to determine the singularity-free zones in the workspace of parallel manipulators is highly important. in this thesis a simple and new technique are presented to determine the maximal singula...
15 صفحه اولPolymer Characterization: Polymer Molecular Weight Determination
Polymers are large molecules consisting of a large number of small component molecules chemically linked together. They are made from constituent monomers through polymerization process. Polymers are unique materials in that they consist of a statistical distribution of chains of varying lengths, and each chain consists of monomer residues which affect its properties hence they require several ...
متن کاملPreparation and molecular weight determination of soya-beans and benniseed oil-modified alkyd resins
Alkyd resins were prepared into four different sets by varying the percentage concentrationof the glycerol content. Various properties such as the viscosity, Surface drying time, solubilityand color of the alkyd resins were evaluated for the various sets. The alkyd resin with the highestglycerol content was the most viscous, brownish in color and having the highest molecularweight this is due t...
متن کاملDetermination of low molecular weight heparin in clinical laboratory.
The applicability was investigated of automated spectrophotometric heparin assays and three clotting assays for determination of two low molecular weight (LMW) heparin fractions: Org 10172 and DxN10 and two infractionated commercially available heparins. The relative activity of the two commercially available heparins was similar in the anti-Xa assay, in the anti-IIa assay and in 3 clotting ass...
متن کاملModernization of Enoxaparin Molecular Weight Determination Using Homogeneous Standards
Enoxaparin is a low-molecular weight heparin used to treat thrombotic disorders. Following the fatal contamination of the heparin supply chain in 2007-2008, the U.S. Pharmacopeia (USP) and U.S. Food and Drug Administration (FDA) have worked extensively to modernize the unfractionated heparin and enoxaparin monographs. As a result, the determination of molecular weight (MW) has been added to the...
