Materials‐Driven Additive Manufacturing for Electrical Machines: Qualification‐Oriented Design Beyond Geometric Freedom

open access: yesAdvanced Engineering Materials, EarlyView.
This perspective reframes additive manufacturing for electrical machines as a qualification‐limited materials and architecture design problem. It links process–structure–property–performance relationships to magnetic, conducting, dielectric, and thermal property windows, highlighting where AM can enable segmented magnetic circuits, permanent magnet ...

Non-Axisymmetric Effects on Long Liquid Bridges [PDF]

open access: yes, 1987
The stability of long liquid bridges under non-axisymmetric disturbances like a microgravitational force acting perpendicular to the liquid bridge axis or a non-coaxiality of the disks is analyzed through an asymptotic method based on bifurcation ...

Enhancement of the Through‐Thickness Electrical Conductivity of Carbon‐Fiber‐Reinforced Plastics Using Large Graphite Particles

open access: yesAdvanced Engineering Materials, EarlyView.
To enhance through‐thickness conductivity without sacrificing impregnation, large spherical graphite particles are intentionally employed in a low‐viscosity resin. Unlike finer conductive fillers, these particles remain outside the fiber bundles and accumulate in resin‐rich interlaminar regions during molding.

Bridges photograph collection, circa 1893-1960s

open access: yes, 1893
This collection contains postcards and photographic prints of pontoon, highway, railroad and other bridges over the rivers in Arkansas, including the Albert Pike Highway bridge (1922), Frisco Railroad bridge (before 1916), Gould Railroad Bridge (ca. 1900-

Thermal bridges [PDF]

open access: yes, 2012
This thesis presents the thermal bridge as a "serious problem in the building envelope" where the heat insulation layer is often broken, wet or otherwise damaged which often happens as a result of poorly designed details in wall protrusions (balconies ...

NUMERICAL INVESTIGATION OF THE EFFECT OF INSULATION ON HEAT TRANSFER OF THERMAL BRIDGES WITH DIFFERENT TYPES

open access: yes, 2016
In the present study, the effects of dfferent types thermal bridges formed by beams for floor-wall junctions in reinforced concrete structures, with and without balconies, and the optimum configuration of the insulation layers to avoid heat loss were ...

A mathematical model for assessment of material requirements for cable supported bridges: implications for conceptual design [PDF]

open access: yes, 2012
Recent technological developments have led to improvements in the strengths of materials, such as the steel and wire ropes used in the construction of cable supported bridges.

Rotary 3D Printing With Integrated Electroplating

open access: yesAdvanced Engineering Materials, EarlyView.
A rotary material extrusion platform integrates localized copper electroplating with printing and encapsulation to fabricate cylindrical polymer–metal structures containing fully embedded, low‐resistance conductive pathways that enable internal Joule heating and thermally activated shape‐memory responses.

Linear oscillations of axisymmetric viscous liquid bridges [PDF]

open access: yes, 2000
Small amplitude free oscillations of axisymmetric capillary bridges are considered for varying values of the capillary Reynolds number C-1 and the slenderness of the bridge Λ .
