Effects of selected factors on sawmill residue wood chip quality
… and anvil condition on the amount of over thick, oversize, accept, pin and fine chips produced from edgings, 6"x6" cants and trim blocks and 2) to recommend changes in processing sawmill residues to minimize the production of over thick, pin and fine chips. Ten trials were conducted at the …

Development of a wet fine screen model integrating the effect of operating and design variables on screening performance
… UG2 and chromite ore blend. Screen undersize and oversize samples were collected for particle size distribution analysis and mass balance calculations. The samples collected were filtered, de - lumped and split down to masses ranging between 200 and 300 grams for wet screening using the Malvern …

The Prediction of The Thermal and Hydraulic Performance of Underground Electric Transmission Systems With Turbulent Forced Convection Cooling
… were considered, corresponding to standard and oversize enclosure pipes. Helical wire wrap was included to simulate protective skid wires around the cables. Three configurations of cable positioning were considered.

The underwater separation of diamantiferous marine gravels
… was a converging elutriator which separates the oversize gravel from the smaller diamond-bearing gravel, using their varying particle settling velocities in an upward flowing fluid. The cyclosieve and spirosieve are two other choices that both use rotational flow to create a centrifugal force, …

Simulation of a vertical ground-coupled heat pump system with optimal ground loop design
… in this design. Care should be taken not to oversize or undersize the equipment that would result in increased installation and operating costs. (Abstract shortened by UMI.).

Decision making for bridge stock management
… on the legal issues entailed by overweight/oversize load permits issued by transportation agencies. Indeed, correct decision-making should consider the legal liabilities involved in possible catastrophic events. In this thesis I illustrate how this problem is guided by the Department of …

Design and testing of a prototype in-line chip quality monitor
… screen drum separator to divide chips into oversize, accepts, and pins/fines. Counterbalanced tip buckets are used to weigh each size class. Tip bucket cycles are recorded by a computer via magnetic proximity switches attached to each bucket. This information is then used to chart production …

Go Cry About It!
… while my sculptures are often exaggerated, oversize forms, emphasizing the passage of time.</p> <p>From January 1st to December 31st of 2024, I kept a record of every time I cried in a spreadsheet. My thesis explores the emotional release and absurdity of crying through the unpredictability …

Factors affecting sawmill residue chip quality
… onto a screen pack with the top screen blinded. OVersize chips were not re-chipped. Material types included cants as controls, slabs, edgings, and trim blocks. Chipper rim speeds included the manufacturerJs recommended 3,385 meters per minute along with 2,370 meters per minute and 1,693 meters …

Evaluation of Methods for Improving Classifying Cyclone Performance
… are misplaced by hydraulic carryover into the oversize product. The unwanted misplacement can have a large adverse impact on downstream separation processes. One method of reducing bypass is to inject water into the cyclone apex. Unfortunately, existing water injection systems tend to …

Validation of a Simplified Building Cooling Load Model Using a Complex Computer Simulation Model
… such as minimum make-up air, cooling capacity oversize, and internal equipment load was investigated. The error bound was determined to be within ±15 per cent for both cases and almost all variations.

Simulated Response of Degrading Hysteretic Joints With Slack Behavior
… and bolt holes are permitted to be drilled oversize resulting in a slack system. The model consists of five parts. A new mathematical hysteresis model describes the stiffness of the individual bolt at each time step increment and accounts for non-linear and slack behavior; a …

Quantifying AAAs and developing FEA models for stent grafts
… the unit is found to be strongly affected by the oversize of the device, yet its radial force is mainly influenced by the friction of the vessel/stent interface. The effects of non-circular aortic cross sections are also examined and mean aortic diameter approximations are shown to be superior. …

Planning studies for distribution grids with high penetration of distributed energy resources: the challenge of fairness in future electricity networks
… for planning in distribution networks of "oversize, fit and forget" is not enough. A review of the literature in grid planning shows that the current focus is on transmission-network-inspired methods that are not realistically scalable for the distribution network case. Accordingly, this …

Improving sawmill residue chip quality
… entering a residue chipper. Trim ends and oversize chips contributed the most pieces, but only 10% of the residue weight. Two-foot trim blocks accounted for the remaining material, 90% by weight. A number of these pieces resulted from slashing entire boards or cutting longer trim lengths …

Design and Comparison of Induction Motor and Synchronous Reluctance Motor for Variable Speed Applications: Design Aided by Differential Evolution and Finite Element Analysis
… the results suggest that there is no need to oversize the Variable Frequency Drive (VFD) in using the Synchronous Reluctance Motor (SRM) in spite of its modest power factor, the outcomes also demonstrate that the only disadvantage in the Synchronous Reluctance Motor is a lower overload …

Overweight Vehicle Permitting Alternatives
… the United States, individual states administer oversize and overweight vehicle permit programs to regulate and collect revenues from overweight operations. Differences in the truck size and weight limits and overweight permit programs across the states inhibit seamless and efficient truck travel …

An Investigation of Anchor Nut Loosening and Review of Tightening Procedures for Anchor Rods in Highway Ancillary Structures
… pose a potential concern. Anchor nuts are tapped oversize after galvanization to ensure the nuts fit well on the galvanized rod. American Society for Testing and Materials (ASTM) standards provide specific allowable tolerances on the thread parameters of the anchor rod and nut after galvanization …
