General sparse elimination is designed to take maximum advantage of the sparsity of an N ×N matrix A. Only the nonzeros of A are stored, along with some extra integer overhead to identify the nonzero matrix elements. This extra integer storage may be avoided for the triangular factors generated by an LDU decomposition, generally without increasing the order of complexity. In addition to permane...

In rail freight operation, freight cars need to be separated and reformed into new trains at hump yards. The classification procedure is complex and hump yards constitute bottlenecks in the rail freight network, often causing outbound trains to be delayed. One of the problems is that planning for the allocation of tracks at hump yards is difficult, given that the planner has limited resources (...

Temporary crediting of carbon storage is a proposed instrument that allows entities with emissions reductions obligations to defer some obligations for a fixed period of time. This instrument provides a means of guaranteeing the environmental integrity of a carbon sequestration project. But because the user of the temporary credit takes on the liability of renewing it, or replacing it with a pe...

Rough rice (cv. Cypress) from the 1995 season was harvested, dried, and stored in laboratory-scale studies. Treatments included pre-drying conditions, drying conditions, storage temperatures, and storage durations. Temporary wet storage prior to drying affected cooking properties (p<0.005) and peak viscosity (p<0.005). Drying treatments affected head rice yield (p<0.05), cooking properties (p<0...

After the accounting informatization, the original vouchers, ledgers and statements have been translated into varieties of data to be stored in computers; however, the storage strategies of these data will be affected by the accounting information processing procedure, such as temporary storage, translation storage and back-up of the documents data, the generation and output of ledger data and ...

PT ABC is an industry that produces hazardous and toxic waste. All waste generated stored in temporary storage, but based on observations made, the existing storage does not meet standards set by government. Therefore, a area was redesigned at accordance with The objective of this study to find place complies government regulations for ABC. method used record types, characteristics, quantities ...

This study introduces a field oriented controlled (FOC) induction machine based flywheel energy storage (FES) system fed from a 20kHz ac link and Pulse Density Modulated (PDM) Converter. The feasibilty of FES system is investigated both in software and hardware and is demonstrated succesfully in both cases. The investigated system offers a good potential as a temporary energy storage system for...
