Radiative cooling, a passive cooling technology, functions by reflecting the majority of solar radiation (within spectrum 0.3-2.5 μm) and emitting thermal atmospheric windows 8-13 μm 16-20 μm). Predominantly, synthetic polymers are effectively utilized for radiative while posing potential environmental hazards due to their complex components, toxicity, or nonbiodegradation. Bacterial cellulose, natural renewable biopolymer, stands out its environmentally friendly, scalability, high purity,...

As one of the most important physical fields for battery operation, regulatory effect temperature on growth lithium dendrites should be studied. In this paper, we develop an optimized phase field model to explore Li in metal batteries. We incorporated full deposition kinetics, including atom diffusion and solid electrolyte interface restriction into revealed their significance determining transformation morphology from moss-like dendrite-like. found that a high or dispersed hot spots are...

Peanut allergy appears to be less prevalent in other parts of the world than North America and several European countries, it has been proposed difference cooking practices may responsible. In this study, boiling roasting processes were investigated find a potential method enhanced or reduce allergenicity.The allergenicity different peanut products, as reflected by changes ethology (diarrhea weight loss) pathology (splenomegaly jejunum breakage) observed, relevant serological indexes...

On the basis of in-depth understanding teaching model CDIO project education, practice system computer major was constructed. The "project driven" based practical used to deepen students' theoretical knowledge, equip students with ability develop actual engineering systems, and train solve problems innovation team spirit. Practice proved that is an effective model.

The characteristics of X-ray testing image are analyzed and an edge detection algorithm based on the multi-scale multi-resolution wavelet transform is proposed. According to propagation modulus maximum under different scales relationship between Lipschitz exponent, local maxima in vertical, horizontal diagonal directions detected by quadratic B-spline Mallat was used decomposition determine defect edges. experiment results prove that works fine images.

Practical teaching is an important part of computer education, practical especially in the education fundamental programming. According to features course construction on C programming, interest-driven based contents and experimental methods are introduced idea "interest-driven practice, Application guide innovation" proposed this paper.

Honey bees can forage nectar from a large spectrum of nectariferous flowers using their rhythmically erectable tongue hairs in viscous dipping fashion that involves faster protraction stroke toward the pool and slower retraction backward. Since honey are capable hairy tongues to adapt various feeding environments, kinematic characteristics bee tongue, especially time, would likely represent evolutionary optimization. However, phenomenon mechanism remain elusive. In this combined experimental...

A road boundary detection method based on statistical test is proposed in which edge location and orientation are considered. The evidence of global boundaries the image can be obtained by means model analysis. Through test, a multi-order line segment description achieved. results satisfied when this used structured with dim shadows.

This paper develops flexible wing model with aileron, investigates the nonlinear limit behaviors using wind tunnel test. Freeplay is introduced into deflection freedom degree aileron. Structural...

For most coefficients of wavelet image are zero, SPIHT algorithm which divides the list insignificant pixels(LIS) into type A and B carries out classification judgment to each node in leads time cost increasing encoder. This paper introduces a kind base(V9/3) with human vision properties lifting transform, cancels procedure LIS algorithm, merges modified processing that node, encodes significant universally accordance sequence spatial orientation tree from son generation grandson generation....

In view of the fact that wavelet coefficients cannot be utilized completely with EZW method and encoding efficiency is reduced by too much time consumed in process successive approximation quantization, an improved image coding algorithm based on lifting transform proposed. this used to improve procedure traditional transform. By modifying scanning strategy quantization threshold high low frequency sub-bands are manipulated separately. The experiment results show can quality recovered efficiency.

Wavelet transform is not the optimal or most sparse function representation for two-dimension images. Contourlet transform, as a kind of Multi-scale Geometric Analysis (MGA) methods, extends advantages wavelet to high dimensional space. It can describe properties information better and more suitable processing with hyper-plane singularity. In this paper, visual weighted image coding algorithm was proposed, in which Wavelet-Based Transform (WBCT) combined SPECK algorithm. According...

Connector-based component assembly is an effective way to reuse components. Combing with the status of Component model and method based connector, this paper puts forward a named KRC (Knowledge Reasoning Connector) which on knowledge reasoning. This connector module using virtual modes encapsulate internal controls in component, mechanism can let Control, coordinate interaction between components active way. The Frame work 4.0 platform has been well applied application system GUBD(Gas Under...
