Abstract The effect of carbon fiber Z-pin on composite under moisture condition with and without flexural load was investigated in this work. Moisture absorption property crack propagation reinforced epoxy matrix Z-pinned were evaluated only moisture-coupled conditions. by content microscopic morphology obtained using X-ray micro-computed tomography (X-ray μCT). microstructures inside composite...

This work presents a different use of COMSOL, not only as a simulation platform for engineering tasks, but also as an integrated component of a computational AI tool framework used to automate designs creation. CNS-Burst is a computational synthesis method used to create solutions to an assigned design task. This search method, iteratively applied, finds design alternatives and represents them ...

A PCI Express (PCIe) to optical link interface (PEXOR: Pci-EXpress Optical Receiver) was developed to connect front end boards to standard PCs. The center of the PEXOR is a high performance Lattice FPGA connecting three main components together: 1) A four lane PCIe endpoint device (4*2.5 Gbits/s). 2) Four high speed optical transceivers (4*2 GBits/s, SFP [1]) as inputs for front end electronics...

we have designed a new type of optical channel drop filter (cdf) based on two dimensionaltriangular lattice photonic crystals. cdf operation is based on coupling to the photonic crystalwaveguide. the proposed structure is optimized to work as a cdf for obtaining the cdfcharacteristics and band structure of the filter the finite difference time domain (fdtd) method andplane wave expansion (pwe) ...

We present infrared transmittance and reflection modulation spectra for changes in the reverse bias voltage across a variety of amorphous silicon (a-Si:H) based pin and min solar cells and diodes. The spectra originate with the change in charge state of levels near the two intrinsic-layer interfaces. The spectra vary significantly for differing interfaces, and we therefore propose their applica...

Major space agencies have an increasing interest in highly accurate (200 m) autonomous landing on the Moon. Inertial-only navigation is not compatible with this challenging requirement. The techniques currently investigated rely on vision-based navigation. A first approach consists in tracking features between sequences of images in order to measure the angular rate as well as the direction of ...

To pursue the insensitivity to feature noise and the stability to re-sampling, a new type of support vector machine (SVM) has been established via replacing the hinge loss in the classical SVM by the pinball loss and was hence called a pin-SVM. Though a different loss function is used, pin-SVM has a similar structure as the classical SVM. Specifically, the dual problem of pin-SVM is a quadratic...
