Intraosseous ultrasound imaging is valuable for guiding pedicle screw placement in surgery. However, single-frequency ultrasound, whether low or high, often fails to provide both adequate resolution and depth simultaneously. To address this limitation, we introduce a novel ultrafast multi-frequency patch fusion method navigation. This approach combines the strengths of high-frequency low-frequency images, greatly enhancing detail clarity resulting images while significantly reducing time...
In this paper, we report the electrical simulation results of a proposed GaInP nanowire (NW)/Si two-junction solar cell. The NW physical dimensions are determined for optimized energy absorption and current matching between each subcell. Two key factors (minority carrier lifetime, surface recombination velocity) affecting power conversion efficiency (PCE) cell highlighted, practical guideline to design high-efficiency is thus provided. Considering bulk defects in semiconductor, promising PCE...
In this paper, single deeply corrugated diaphragms (SDCDs) with various corrugation depths and initial stresses are studied extensively for applications to micromachined high-sensitivity devices. Finite-element model simulation results show that significant improvement in mechanical sensitivity can be achieved using a SDCD larger depth. The diaphragm has been applied the fabrication of microphone. measurements structure is promising its
Dual-frequency ultrasounds have demonstrated significant potential in augmenting thermal ablation efficiency for tumor treatment. Ensuring proper impedance matching between the dual-frequency transducer and power amplifier system is imperative equipment safety. This paper introduces a novel network utilizing L-shaped topology employing genetic algorithm to compute component values. Implementation involved an adjustable capacitor inductor achieve matching. Subsequently, acoustic parameters of...
The low frequency oscillation is a serious threat to security and stability of power grid. How locate the disturbance source accurately an important issue disposal. Existing methods have poor adaptability with time-varying steady-state points because limitations in location criterion derivation. A method on good generality presented paper. Firstly, reasons why are analyzed. Then, based energy function construction form, branch transmission decomposed into state energy, reciprocating...
The insertion of pedicle screw is the most important step to fuse damaged spines in spinal fusion surgery. Intraosseous ultrasound imaging can be used guide screw. However, it difficult for an intraosseous image obtain high resolution and deep penetration simultaneously. To address these issues, a micro dual-frequency single element transducer was designed based on thickness contour modes our previous work. For further image, we proposed multi-frequency method wavelet transform (WT) which...
Speculative execution is the key technology to improve efficiency of Hadoop cluster.In large-scale cluster reasonable can effectively reduce time for job.At present, there still a big problem in detecting Hadoop's .Therefore this paper proposes self-learning dynamic adjustment scheduling algorithm.The algorithm firstly study impact historical information task execution, dynamically adjusts proportions each stage Reduce tasks And taking into account different types load effect on detection...
MapReduce is a popular big data processing tool, but there exists main node failure problem.In order to make the restarted JobTracker recover jobs site quickly, are mainly two recovery mechanisms: synchronization mechanism and backup mechanism.In mechanism, TaskTracker sends synchronous message within required time in without considering dependency between Map Reduce tasks, which leads congestion.Using recovers based on records ignoring assigned tasks intervals (which called zombie...
Intraosseous ultrasound imaging can serve as a guiding tool for the placement of pedicle screws during spinal fusion surgery; thus far, there has been limited scholarly exploration methods intraosseous multifrequency imaging, which achieve simultaneous high resolution and deep penetration. The proposed method introduced dynamic strategy grounded in wavelet transformation image decomposition. This accomplished effective amalgamation high-frequency images low-frequency images, enabling...
