Efficient Surface-wave Excitation by Parallel-Plate Waveguide for Substrate Integrated Image Guides

Cluster Centers Provide Good First Labels for Object Detection

Learning object detection models with a few labels, is possible due to ingenious few-shot techniques, and due to clever selection of images to be labeled. Few-shot techniques work with as few as 1 to 10 randomized labels per object class. We are curious if performance of randomized label selection can be improved by selecting 1 to 10 labels per...

A Simple and Efficient Procedure for Identifying the Compressing Stage in Two-Stage Amplifiers

We propose a fast and simple method to accurately determine the compressing stage in a two-stage amplifier system based on reverse intermodulation and hot S-parameter measurements. The method uses no specialized hardware and needs little reconfiguration, simplifying the measurements. We demonstrate its validity over a broad range of amplifiers...

Modelling of the over-exposed pixel area of CCD cameras caused by laser dazzling

A simple model has been developed and implemented in Matlab code, predicting the over-exposed pixel area of cameras caused by laser dazzling. Inputs of this model are the laser irradiance on the front optics of the camera, the Point Spread Function (PSF) of the used optics, the integration time of the camera, and camera sensor specifications...

Contour Detection by CORF Operator

We propose a contour operator, called CORF, inspired by the properties of simple cells in visual cortex. It combines, by a weighted geometric mean, the blurred responses of difference-of-Gaussian operators that model cells in the lateral geniculate nucleus (LGN). An operator that has gained particular popularity as a computational model of a...

A comparison of the Iberian and Ebro Basins during the Permian and Triassic, eastern Spain: A quantitative subsidence modelling approach

The Permian-Triassic sediments of the Iberian Plate are a well studied case of classical Buntsandstein-Muschelkalk-Keuper facies, with good sedimentological interpretations and precise datings based on pollen and spore assemblages, ammonoids and foraminifera. Synrift-postrift cycles are recorded in these facies, but there are only a few studies...

Binaural intelligibility prediction based on the speech transmission index

Although the speech transmission index STI is a well-accepted and standardized method for objective prediction of speech intelligibility in a wide range of environments and applications, it is essentially a monaural model. Advantages of binaural hearing in speech intelligibility are disregarded. In specific conditions, this leads to considerable...

Microstructure formation and rheological behaviour of dough under simple shear flow

In a z-blade mixer, both shear and extensional deformations contribute to the development of dough structure. I effect of simple shearing versus z-blade mixing at similar levels of work input, on the microstructure and uniaxial extensional properties of two doughs prepared from flours of different strengths. With respect to microstructure,...

Effect of simple shear on the physical properties of glutenin macro polymer (GMP)

Gluten plays a key role in determining the end-use quality of wheat flour. The important role of the highly aggregated fraction of gluten, glutenin macropolymer (GMP), in dough properties opens up new possibilities for revealing underlying mechanisms related to dough processing. Using a new shear cell and advanced methodology to study the GMP,...

Toxicological evaluation and risk assessment of chemical mixtures

A major objective of combination toxicology is to establish whether a mixture of chemicals will result in an effect similar to that expected on the basis of additivity. This requires understanding of the basic concepts of the combined toxicological action of the compounds of the mixture: simple similar action (dose addition), simple dissimilar...
