An image segmentation method for human gesture analysis is proposed deriving from the concept of opportunistic vision-based feature fusion. The method for human body part segmentation in image sequences is motivated by a layered and collaborative architecture for gesture analysis in multi-view camera networks. The layered structure aims to accommodate the diversity of gestures while collaborati...

We investigated the effects of violations of the sphericity assumption on Type I error rates for different methodical approaches of repeated measures analysis using a simulation approach. In contrast to previous simulation studies on this topic, up to nine measurement occasions were considered. Effects of the level of inter-correlations between measurement occasions on Type I error rates were c...

The paper describes an application of a one class KNN to identify different signal patterns embedded in a noise structured background. The problem becomes harder whenever only one pattern is well-represented in the signal; in such cases, one class classifier techniques are more indicated. The classification phase is applied after a preprocessing phase based on a multi layer model (MLM) that pro...

COMAIDE is a toolkit for user-system cooperation through joint multi-focal graph browsing. It supports cooperative force-directed layout management, concurrent with dialogue handling, for heterogeneous multi-layered 3D interactive diagrams. The layout manager's intu-itively`natural' animations of multi-layered 3D graph drawings support: 1. Cooperative tidying of user-manipulable 3D layout; 2. O...

Herein we report on a general approach to delaminate multi-layered MXenes using an organic base to induce swelling that in turn weakens the bonds between the MX layers. Simple agitation or mild sonication of the swollen MXene in water resulted in the large-scale delamination of the MXene layers. The delamination method is demonstrated for vanadium carbide and titanium carbonitride MXenes.

We present a simple, robust, and practical method for object simplification for applications where gradual elimination of high frequency details is desired. This is accomplished by converting an object into multi-resolution volume rasters using a controlled filtering and sampling technique. A multiresolution triangle-mesh hierarchy can then be generated by applying the Marching Cubes algorithm....

Carbon fiber-reinforced multi-layered pyrocarbon-silicon carbide matrix (C/C-SiC) composites are widely used in aerospace structures. The complicated spatial architecture and material heterogeneity of C/C-SiC composites constitute the challenge for tailoring their properties. Thus, discovering the intrinsic relations between the properties and the microstructures and sequentially optimizing the...

The microstructure and mechanical properties of the solid electrolyte interphase (SEI) in non-aqueous lithium ion batteries are key issues for understanding and optimizing the electrochemical performance of lithium batteries. In this report, the three-dimensional (3D) multi-layered structures and the mechanical properties of the SEI formed on a silicon anode material for next generation lithium...
