Bottomless continuous-time continuous-state two-machine transfer line
… continuous-material, mixed-state transfer line with an allowance for negative inventory. The production line consists of two-machines separated by a storage area with a maximum storage level N, and minimum storage level -[infinity]. In other words, inventory level is allowed to be …

Alternatives to the gradient in optimal transfer line buffer allocation
… We find that the new algorithms work better in lines with no bottlenecks. The variance and standard deviation algorithms work very well in most cases. We also include an algorithm to generate realistic line parameters. This algorithm generate realistic line parameters based on realistic …

Redesigning experimental equipment for determining peak pressure in a simulated tank car transfer line
… valve openings can cause pressure surges in the transfer line. To model this phenomenon and predict the peak pressures in such a transfer line, a laboratory setup consisting of a pressurized water storage tank connected to different segments of pipe by ball valves was constructed. By varying …

Design and development of a transfer system for an automated packaging machine
… on the design, development and production of a transfer line as part of the aforementioned machine. After being fed into the sorting and orienting stage in loose bulk, the vials are transferred into the packaging stage through the transfer line. The designed machine will contribute to the …

The Performance Comparison of Fixed and Flexible Buffer Allocation Systems in Automated Transfer Lines (Production Management, Assembly Line)
… important problems in the design of an automated transfer line is the allocation of buffers under the restriction of an overall buffer limit. In the first part of the research, new heuristics are developed for the case of fixed buffer sizes, so as to maximize production efficiencies. Unlike the …

Design and development of a precision packing stage and master control system for an automated vial packaging machine
… orienting and feeding the vials while a simple transfer line mechanism queues and loads them for packaging. For the mechanical alignment of certain motion elements elastic averaging was utilized to achieve satisfactory vial dispensing performance. A simple motion control system was developed …

Design and implementation of flexible manufacturing systems: some analysis concepts
… flexible manufacturing system as a programmable transfer line is explored. SIM-Q is also used in this study to test the robustness of CAN-Q in modelling an existing FMS. A linear zero-one linear programming model is formulated for the machine mapping and pooling problem. The system synthesis …

Simulation study of a semi-automated flexible production line
… improving it means that experimentation on the line itself is often a risk not worth taking. One solution to this problem is the use of computer based manufacturing system simulation. Simulation studies are beneficial because they remove the element of risk associated with experimentation. …

Nitrogen Abundances in Early-Type Be Stars
… equatorial disk of gas that produces emission lines in their optical and near-infrared spectra. Be stars are the most rapidly-rotating stellar population on the main sequence, where stars produce energy by core hydrogen burning. New, non-LTE line transfer calculations are performed for the Nii …

FUNDAMENTAL AND APPLIED MEASUREMENTS IN ICP-MS
… rapidly with increasing temperature of the transfer line between the particle beam separator and the LP-ICP torch. This was also supported by the fact that more volatile compounds gave mass spectra whereas less volatile compounds did not. A limit of detection of 30 mg 1'^ for chlorobenzene …

The fluidized retorting of oil shale from the Mahogany ledge of the Green River formation of Colorado
… Additional heaters were provided on the gas transfer line to reduce the heating time. The condensers were simple tube-in-shell heat exchangers constructed from 1-1/2-inch and 3/4-inch deoxidized copper pipe with headers for the oil receivers. The condensers were designed and constructed to …

Variable Temperature Scanning Tunneling Microscopy Study of a High Temperature Superconductor Bi2Sr2CaCu2O8+d
We have used a custom-built scanning tunneling microscope (STM) to investigate the electronic states of a slightly underdoped high-TC superconductor Bi2Sr2CaCu2O8+d as a function of temperature. We have demonstrated for the first time that atomicallyresolved spectroscopic studies at elevated …
