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 اولSequential determination of free and total cyanide by flow injection
This study presents a flow injection system for the sequential determination of free (CN(-)) and total (CN(-)+ HCN) cyanide using a potentiometric method which employs two different processes for the determination of these two chemical species. The first process is based on direct detection of CN(-) using an ion-selective electrode for cyanide. In the second process, the sample is mixed with ac...
متن کاملDetermination of Free Cyanide and Total Cyanide Concentrations in Surface and Underground Waters in Bogoso and Its Surrounding Areas in Ghana
Concentrations of free cyanide and total cyanide in water samples in Bogoso and its surrounding areas in Ghana have been measured in this study. Concentrations of free cyanide and total cyanide were found to be above the maximum permissible discharge limit of effluent from mining companies into natural waters set by Environmental Protection Agency, Ghana (GEPA). A comparison of the results obta...
متن کاملDetermination of total dissolved inorganic carbon in freshwaters by reagent-free ion chromatography.
Studies of inorganic carbon cycle in natural waters provide important information on the biological productivity and buffer capacity. Determination of total inorganic carbon, alkalinity and dissolved carbon dioxide gives an indication of the balance between photosynthesis and respiration by biota, both within the water column and sediments, and carbon dioxide transfers from the water column to ...
