In order to improve the color saturation of textile structured chromogenic photonic crystals, this paper proposes that dye adsorbed PSt structural elements (reactive dyes/PSt microspheres) on outer surface can be used construct electrochemically crystals mulberry fabrics by digital printing. method, adsorption conditions and model dyes colloidal microspheres were studied. The structure morpholo...

Interest in thin films of functional materials has increased enormously in recent years because of the wide range of possible applications. Here we report an experimental setup we have termed Atmospheric-Pressure Ion Deposition (APID) as a novel technique that allows highly controllable and soft processing of various materials (e.g. polymers, bio molecules and inorganic materials) into thin and...

This chapter introduces the principles and difficulties of time-of-flight depth measurement. The depth-images that are produced by time-of-flight cameras suffer from characteristic problems, which are divided into the following two classes. Firstly there are systematic errors, such as noise and ambiguity, which are directly related to the sensor. Secondly, there are non-systematic errors, such ...

This study examines the influence of instructional design and management style on student achievement and satisfaction in a web-based distance learning environment. From the literature review, two major instructional design and management styles in web-based distance education were conceptualized as structure and interpersonal interaction. To investigate the differences on learning output varia...

Increasing material’s strength is of particular importance. Improving material’s mechanical properties such as strength could reduce the size and weight of the structure. The size and weight of the structure are among the effective parameters in design. Since the past a variety of methods have been developed to increase the strength of metals that are capable of increasing metals’ strength to a...

The system CuGaSe2 CuGa3Se5 in thin films has been investigated. Layer synthesis was carried out by chemical close-spaced vapour transport (CCSVT) using Cu precursors on Mo/soda-lime glass substrates. The extension of deposition times in a two-step process led to final film compositions with [Ga]/[Cu] ratios ranging from 1 to 3, allowing the study of the phase transition mentioned above. Films ...

In this work we study the reflection of circularly polarised light from a nano-structured biological material found in the exocuticle of scarabus beetles. This material is made of a stack of ultra-thin (~5 nm) uniaxial layers arranged in a left-handed helicoidal stack, which resonantly reflects circularly polarized light. A chirp in the layer thickness combined with a finite absorption coeffici...

Catalyst selectivity is associated with well-defined homogeneous active sites. Transition metal complexes and organocatalysts are highly active and selective in the homogeneous phase, and their heterogenization by incorporating them into inorganic solid materials allows combining their excellent catalytic activity with improved separation, recovering and recycling properties. In this article, w...

Computer simulations reveal how photoinduced chemical reactions in polymeric mixtures can be exploited to create long-range order in materials with features that range from the submicron to the nanoscale. The process is initiated by shining a spatially uniform light on a photosensitive AB binary blend, which thereby undergoes both a reversible chemical reaction and a phase separation. When a we...

3. Per-Class Detection Performance Although we obtain superior overall detection performance, it may also be of interest for audience to see the per-class performance. Due to space limit in the text, we present the per-class average of AP values using SSN on ActivityNet v1.2 validation set in Table 1. The average AP values are measured by varying the IOU thresholds from 0.5 to 0.95 in the step ...
