Herein this study, plasmonic‐patterned nanostructures are applied to fabricate unclonable anti‐counterfeiting labels. Patterned Au nanoparticles (AuNPs) constructed by the skillful combination of diblock copolymer polystyrene‐block‐poly(4‐vinyl pyridine) (PS‐ b ‐P4VP) self‐assembly with shadow mask lithography provide a simple and universal approach for large‐area fabrication patterned nanostructures. The AuNP pattern can be made visible increasing nanoparticle size. A surface‐enhanced Raman...

This article presents a wearable lower extremity exoskeleton (LEE) designed to augment the ability of human walk while carrying payloads. The ultimate goal current research is design and control power-assisted system that integrates human’s intellect as command. in this work consists an inner outer exoskeleton. measures movements controls system, which follows supports payload. A special foot-unit was measure zero moment points (ZMPs) simultaneously. Using measured ZMP reference,...

Exoskeletons for human performance augmentation are controlled and wearable devices or machines that can increase the speed, strength, endurance of operator. So far most researchers focus on upper limb exoskeletons. To help those who need to travel long distances by feet with heavy loads such as infantry soldiers, this paper presents a control principle lower extremity exoskeleton. An exoskeleton foot is designed measure exoskeleton's ZMP. Using measured ZMP reference together leg position...

Exoskeletons for human performance augmentation are controlled and wearable devices that can increase the speed, strength, endurance of operator. To help those who need to travel long distances by feet with heavy loads such as infantry soldiers, we developing a lower extremity exoskeleton fur enhancement at Nanydng Technological University (NTU). Together linkages, an foot is designed measure exoskeleton's ZMP. Ry using measured ZMP leg position signals, be modified hy trunk compensation....

Inspired by the functional microstructure of ant nest, a humidity control material was prepared sintering modified low-grade sepiolite. A hierarchical porous structure accelerates diffusion water vapor. Meanwhile, CaCl2 applied subtly to enhance absorption/desorption vapor in response change air relative humidity. The adsorption–desorption content reaches 550 g·m–2 with steady performance after 10 cycles. flexural strength specimen is excessive, MPa. Furthermore, two model houses were used...

The synthetic jet piezoelectric air pump is a potential miniature device for electronic cooling. In order to improve the performance of device, small-sized proposed in this work, which mainly characterized by petal-shaped inlet channels. First, structure and working principle vibrator are analyzed. Then, three pumps with different channels compared. These inlets direct channels, diffuser/nozzle respectively. Furthermore, optimized orthogonal tests. Finally, simulation was used investigate...

A 0.9-V supply voltage, high power rejection ratio (high-PSRR) bandgap reference with high-order compensation is presented. By inserting a group of self-cascode current mirrors and adopting an effective technique compensation, this designed in 0.18 μm CMOS process. Simulation has been carried out the results prove that PSRR temperature coefficient (TC) are both improved evidently low voltage. Under 0.9 V reference's -86 dB at 1 kHz -25 MHz, its TC 0.096 ppm/°C from -40 °C to +85 °C,...

Based on comprehensive consideration of stochastic factors and the system performance, we presented an integrated queuing network model(IQNM) to effectively optimize facility layout multi-floor flow shop(MFFS). In this paper, arrival interval service times workstations are described by two-moment approximation method, iterative algorithm is proposed for estimating including mean throughput, work-in-process(WIP) sojourn time. design process, optimization model with throughput cycle time...

Human exploration of space is always ongoing, and satellites play a huge role in this process. Therefore, the stable operation very important, how to detect diagnose satellite faults has become key issue. This paper presents method based on data compression improved decision tree algorithm, which both accuracy efficiency fault diagnosis detection. In experiment, we used actually collected communication telemetry as original set verify performance proposed article. The results show that our...

We present a method for multi-projector seamless tiled display system, and it mainly consists of two steps. Firstly, an ordinary PC (Personal Computer) is used to preprocess the system with software. Secondly, one or more hardware image processors, which are based on FPGAs (Field Programmable Gate Arrays), process source video without aid computers. Experimental results show that proposed effective low cost high performance.

We present a software-hardware cooperative method for multi-projector seamless tiled display system, and it mainly consists of two steps. Firstly, an ordinary PC (Personal Computer) is used to preprocess the system with software.

Inlet distortion is a main resource of performance decreasing compressor, in this way it essential to judge the influence inlet compressor according test. A properly designed generator can simulate practical condition exactly, which key and foundation successful new generation requires proper methods for assessing effect, while naissance development computational fluid dynamics (CFD) provide an easy effective purpose. In article two kinds steam injectors were introduced fan injection test as...

Water-soluble organic acids (WSOAs) are closely related to the formation of secondary pores, however, it's little-known for distributions WSOAs in sedimentary rocks at deep-ultradeep zone and high-over mature stage. In present study, 22 rocks, involving diverse thermal maturities buried depths. Using deionized water extract selected was conducted, then extracts were quantitatively characterized using 940 Ion Chromatography (Metrohm AG). Meanwhile, key factors affecting WSOA also discussed....
