Layered network architectures (OSI, TCP/IP) separate functionality in layers, allowing them to be designed and implemented independently. However, from the security point of view, once a lower layer is compromised, the reliability of the higher layers can be impaired. This paper is about the security of the Data Link Layer, which can affect the reliability of higher layers, like TCP, HTTP and o...

In laser powder bed fusion (LPBF), it is common practice to select process parameters achieve high density parts starting from simple geometries such as cubes or cylinders. However, additive manufacturing usually adopted produce very complex geometries, where should be tuned locally, depending on the local features processed. fact, geometrical features, overhangs, acute corners, and thin walls ...

Optical coherence tomography (OCT) is a noninvasive imaging modality which can be used to obtain depth images of the retina. The changing layer thicknesses can thus be quantified by analyzing these OCT images, moreover these changes have been shown to correlate with disease progression in multiple sclerosis. Recent automated retinal layer segmentation tools use machine learning methods to perfo...

Recent advances in 3D modeling and depth estimation of objects have created many opportunities for multimedia computing. Using depth information of a scene enables us to propose a brand new segmentation method called DepthWise segmentation. Unlike the conventional image segmentation problems which deal with surface-wise decomposition, the depth-wise segmentation is a problem of slicing an image...

Heavy occlusions in cluttered scenes impose significant challenges to many computer vision applications. Recent light field imaging systems provide new see-through capabilities through synthetic aperture imaging (SAI) to overcome the occlusion problem. Existing synthetic aperture imaging methods, however, emulate focusing at a specific depth layer, but are incapable of producing an all-in-focus...

Semantic boundary and edge detection aims at simultaneously detecting object edge pixels in images and assigning class labels to them. Systematic training of predictors for this task requires the labeling of edges in images which is a particularly tedious task. We propose a novel strategy for solving this task in an almost zero-shot manner by relying on conventional whole image neural net class...

Naor and Reingold had proposed the construction of a strong pseudo-random permutation (SPRP) by using a layer of ECB encryption between two layers of invertible block-wise universal hash functions. At Crypto 2007, Halevi presented constructions of invertible block-wise universal hash functions and a new mode of operation (called TET) based on them. In this paper, we present a new mode of operat...

Abstract This work investigates the potential of improving mechanical performance braided composite beams through introduction local braid angle variations. Tubular with a 45°/60°/45° length-wise (axial) variation were manufactured and tested in quasi-static three-point flexure their was compared having layer-wise (radial) [±60°/±45°/±45°] variation. Compared to uniform angles, axial tailoring ...
