Low‐Cost Friction‐Based Force‐Limiting Connection With Reduced Sensitivity to Machining Tolerances and Accelerated Repairability

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT This paper presents a novel yet practical friction‐based structural component design for low‐damage earthquake‐resistant structures. The proposed connection design is based on a conventional slotted‐bolted configuration with the novelty being the use of loose steel washer plates to establish the friction‐sliding interface.

Very High Frequency Galvanic Isolated Offline Power Supply [PDF]

, 2017
I løbet af de sidste årtier er interessen for at øge skifte frekvensen af strømforsyninger til det ”meget høje frekvens” (VHF) område steget markant, VHF frekvensområdet spænder fra 30 MHz til 300 MHz. En øget skiftefrekvens medføre at mindre energi skal lagers i hver periode og derved mindskes værdierne af de passive komponenter.

Heat Transfer Performance of Biphilic Surfaces With Diatomite‐Based Composite Coatings in a Closed Thermosyphon System

Heat Transfer, EarlyView.
ABSTRACT This study investigates the thermal performance of innovative biphilic boiling surfaces designed for CPU cooling applications using a two‐phase closed thermosyphon (TPCT) system. The surfaces were fabricated by applying composite coatings—comprising epoxy resin and diatomite particles functionalized with APTES and PFOTS silanes— onto Al1050 ...
