Fusion frames are generalizations of classical frames that provide a richer description of signal spaces where subspaces are used in the place of vectors as signal building blocks. The main idea of this work is to extend ideas from Compressed Sensing (CS) to a fusion frame setup. We use a sparsity model for fusion frames and then show that sparse signals under this model can be compressively sa...

In this paper we introduce an aspect language that can define crosscutting e ects on a set of UML 2.0 sequence diagrams. The aspects and sequence diagrams are woven at the model level. By basing the weaving upon a formal trace model for sequence diagrams, we ensure that the weaving is semantics-based. We propose the arbitrary events symbol as a wildcard mechanism to express zero or more events ...

Weaving an aspect may introduce undesired impacts on behavior of the base model or other afore-woven aspects. An approach to detect and evaluate the semantic influences of an aspect weaving on a pattern is presented. The pattern specifies a desired behavior that should stay unaltered or occur in the woven model. The detection and evaluation are based on the semantic relationship between a patte...

In this paper we propose a novel approach to the pixel level fusion of spatially registered image sequences. This fusion method incorporates a shift invariant extension of the discrete Wavelet Transform, based on the concept of Wavelet Frames which yields an overcomplete signal representation. The advantage of the proposed fusion method is the improved temporal stability and consistency of the ...

In the Global South, Indigenous and Native people continue to live under colonial relations within formally independent nation-states. Sebastian Garbe offers a critical perspective on contemporary expressions of international solidarity transnational advocacy. He combines approaches from race decolonial studies with an activist ethnography networked spaces encounters created through activism by...

OBJECTIVE To construct four recombinant Lactococcus lactis strains exhibiting high beta-galactosidase activity in fusion or non-fusion ways, and to study the influence factors for their protein expression and secretion. METHODS The gene fragments encoding beta-galactosidase from two strains of Lactobacillus bulgaricus, wch9901 isolated from yogurt and 1.1480 purchased from the Chinese Academy...

background: carpet weaving is an occupation that requires sufficient and appropriate lighting. the lighting in carpet weaving workshops affects the productivity and the physical and mental health of workers. therefore, the evaluation of the illumination and the identification of work stations requiring lighting modifications will be helpful in promotion of the health and safety of workers in ca...

Traditional visual place recognition (VPR), usually using standard cameras, is easy to fail due glare or high-speed motion. By contrast, event cameras have the advantages of low latency, high temporal resolution, and dynamic range, which can deal with above issues. Nevertheless, are prone failure in motionless scenes, while still provide appearance information this case. Thus, exploiting comple...
