Water seepage of building walls is a common problem in our lives. However, the lack early detection methods often makes worse. To develop effective wall methods, an ultrasensitive quartz crystal microbalance (QCM) humidity sensor based on fullerenol (C60-OH)-assisted dispersion Nafion/multiwalled carbon nanotubes (MWCNTs) composites proposed. The prepared shows almost seven times higher frequency shift than pure Nafion-based sensor, which reaches −10814 Hz. This mainly attributed to uniform...
Limited by the adsorption and diffusion rate of water molecules, traditional humidity sensors, such as those based on polymer electrolytes, porous ceramics, metal oxides, typically have long response times, which hinder their application in monitoring transient changes. Here we present an ultrafast sensor with a millisecond-level response. The is prepared assembling monolayer graphene oxide quantum dots silica microspheres using simple electrostatic self-assembly technique. Benefiting from...
In order to evaluate the goodness of frequency hopping sequence design, periodic Hamming correlation function is used as an important measure. Usually, length window shorter than period chosen sequence, so study partial particularly important. this paper, maximum lower bounds sequences with low hit zone, respect size slot set, window, family size, autocorrelation and crosscorrelation are established. It shown that new include known Lempel-Greenberger bound, Peng-Fan bounds, Eun-Jin-Hong-Song...
In composite structures, the shear keys, that is, headed studs or perfobond rib connectors (PBL connectors), are typically subjected to external pressure, owing self-weight of pavement and safeguards, for example. These loads may exert some influence on behavior such keys. To investigate PBL under eight specimens were tested, slip-load curve crack developments obtained. According test results, pressure significantly contributed stiffness strength friction effect. The relative improvement was...
Load carriage is a key risk factor for Muscular Skeletal Disorders (MSDs). As one way to decrease such injuries, some exoskeletons have been developed regular load carriage. We examined the ergonomic potential of an augmentation exoskeleton. Nine subjects completed eight trials carrying tasks, using four loading levels (0, 15, 30, and 45 kg) two conditions (with without exoskeleton). Electromyography (EMG) extended NASA-TLX rating scales were investigated analyzed by linear mixed modeling...
Phosphovanadate Y(V0.2P0.8O4):Eu3+ nanorods have been created via a simple hydrothermal method and used for the highly sensitive selective fluorescence detection of Cr3+ over other common heavy metal ions within 10 min period. It was found that intensity linearly decreases with concentrations ranging from 1 × 10–9 to 1.2 10–6 M. The sensing mechanism is ascribed aggregation triggered by owing high affinity phosphate groups ions. excellent chemical stability, photostability wide pH range...
This work presents the development of an electrochemical microsystem for antipsychotic clozapine treatment monitoring in schizophrenia patients. In our previous work, we demonstrated detection directly spiked whole blood samples a healthy volunteer using chitosan–carbon nanotube-modified microelectrode with external counter and reference electrodes. Here present miniaturization sensing approach its clinical validation real obtained from 10 We observed sensitivity 0.02 ± 2.3 × 10-4 mA/cm2µM...
In this paper, we use homotopy method to transfer nonlinear equations a differential equations, then apply four-order Runge-Kutta solve the for getting more stable and easily convergent solution. What is important, demonstrate complete proof of whole process, which provide scientific foundation as whole. end, give specific example that solved by approach have proved, shows efficiency stability method. With new methods, some certain can be simply precisely caculated, contribute production...
This paper reports a humidity sensor based on TiO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> nanowires. The prepared with simple and easy technology exhibits obviously high sensitivity fast response/recovery speed. A series of analyses including scanning electron microscopy, specific surface area analysis, water contact angle, complex impedance spectrum were used to analyze superior sensing performance results demonstrate that...

In order to evaluate the goodness of frequency hopping (FH) sequence design, periodic Hamming correlation function is used as an important measure. But aperiodic FH sequences matters in real applications, while it received little attraction literature compared with correlation. this paper, new lower bounds for sequences, respect size slot set, length, family size, maximum autocorrelation and crosscorrelation are established. The tighter than Peng-Fan bounds. addition, include second powers...
