A compact pattern-reconfigurable dielectric resonator antenna (DRA) based on magnetoelectric (ME) dipole is proposed in this letter. For DRA, six patches and a working TE <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex-math notation="LaTeX">$_{111}$</tex-math></inline-formula> mode are introduced as the electric (E-dipole) array magnetic (M-dipole), respectively, which form ME-dipoles with dual-mode response. By switching feeding...
In this paper, a flexible pyroelectric sensor using PbZr0·3Ti0·7O3 PZT/P(VDF-TrFE) materials on the polyimide (PI) printed circuit substrate was reported. The fabrication processes, material electric properties and infrared photoelectric response property of designed were studied. First, PZT ceramic powder annealed at temperatures ranging from 300 to 900°C, then 0–3 PZT/PVDF-TrFE composites films produced by casting suspension onto PI substrates. highest coefficient obtained 700°C...
In an actual industrial environment, many systems need to perform multiple missions in succession. order ensure the success of next mission, components require maintenance breaks. this case, there may not be enough time and cost repair every component. Therefore, selective is required between two consecutive missions. a multi-state system, each component also has working states, which makes options during break possible. But different workers will affect states after maintenance. The purpose...
A credit risk identification model is established to examine the status of Energy performance contracting (EPC) project clients (i.e., energy-using companies) in China based on rough set theory. The verified with data from 120 listed companies at different times. Study shows that lack one main obstacles implementation EPC projects, and information asymmetry reason for this among potential China. method theory can make up shortcomings existing projects terms identification, including...
In this article, a novel high-performance fold I shaped junctionless FinFET (FIS JL FinFET) is proposed. Compared to conventional FinFETs, the proposed FIS can realise lower off-state leakage current, parasitic capacitance while ensuring no degradation of subthreshold swing. The electrical properties have been extensively investigated through comprehensive discussions influences resulting from gate geometry engineering.
Electronic products may be subjected to vibration inevitably in the process of transport, storage, and use causing electronic equipment failure. It is necessary estimate fatigue life from board level under random vibration. At present, common method estimating for general structure combine S-N curve with linear damage accumulation theory. Based on this theory, a new prediction model PCB (Printed Circuit Board) Vibration was proposed. The simplified as single-degree-of-freedom system....
This paper deals with the problem of minimizing nulling level (NL) given desired minimum power gain and sidelobe (SLL) via a wide-beam array antenna. Different from traditional approaches which solve shaped beam pattern synthesis (SBPS) problem, tries to further suppress NL by solving (PGPS) problem. We firstly sets up mathematical model discussed then its non-convex structure is transformed into convex one approximation scheme. As result, formulated can be solved effectively available...
Based on the research forming mechanism of textured PCD tool surface, nanosecond laser is used to study influence machining parameters size and topography surface micro texture. The micro-hole texture prepared tool, a single factor experiment designed power, pulse frequency defocusing amount results show that, diameter increases gradually with but decreases frequency; overall tends increase defocus. has greatest impact diameter, followed by defocus amount, finally power. different recast...
This paper proposed a new reliability analysis method which is based on the background of work ultra-high pressure liquid pump. According to specific characteristics phase pump, we studied typical failure mechanism key components. At same time, describing law degradation, taking into account changes in structural characteristics, degenerative process model was proposed. kind modeling can effectively compensate for lack relevant data prediction equipment reliability. Meanwhile, it study...
