Mild heating devices currently available to conservators are still limited in terms of precision, versatility, mobility, accessibility and cost.Moreover, they lack a range of operational features, such as low power requirements, efficient power use, temperature stability and uniform heat distribution.Carbon nanotube- based technologies can provide
The setting direction of the evaluation indicators in the current research and the differences of the research methods in terms of principles, advantages and disadvantages and applicability are compared and analyzed.The results show that the current well-facilitated farmland Denim construction has achieved remarkable results.In the suitability eval
Reminiscence and conversation between older adults and younger volunteers using past photographs are very effective in improving the emotional state of older adults and alleviating depression.However, we need to evaluate the emotional state of the older adult while conversing on the past photographs.While electroencephalogram (EEG) has a significan
Ground-based tests are important for studying hypervelocity impact (HVI) damage to spacecraft pressure vessels in the orbital debris environment.We analyzed the damage to composite overwrapped pressure vessels (COPVs) in the HVI tests and PRO-KERATIN classified the damage into non-catastrophic damage and catastrophic damage.We proposed a numerical
This article presents a double-balanced up-conversion ring mixer based on complementary switches operating at millimeter-wave frequencies.Complementary-switching relieves the mixer from the need for a differential Local-Oscillator (LO) signal, simplifying the design and improving the circuit performance.A prototype, capable of operation between 18
