Compression-ratio-based seizure detection

2013 35th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2013
For wireless seizure monitoring devices seizure detection and data compression are two critical tasks that need to be carefully designed against a very tight power budget to maximize the battery life. These two tasks are usually considered separately and algorithms for each are developed separately.

Variable Compression Ratio Engines

SAE Technical Paper Series, 2009
<div class="htmlview paragraph">The main focus of this work is to study variable compression ratio engines. The study begins with an analyze of the benefits of a variable compression ratio for Otto Cycle engines including mechanisms that already exist, the usual constructive solutions and the project criteria adopted in the area.</div> < ...

Compression Ratio Design in Compressive Spectral Imaging

2016 Data Compression Conference (DCC), 2016
In this work, a compression strategy for Focal Plane Array Measurements (FPA_M) in Compressive Spectral Imaging (CSI) is presented. The strategy is applied to four CSI architectures. The implementation consists of two stages: transformation and coding. The transformation stage is performed according to the FPA_M structure. Finally, an arithmetic coding

Compression ratio prediction in lossy compression of noisy images

2015 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2015
Our paper addresses a question of prediction compression ratio in lossy compression of remote sensing images by coders based on discrete cosine transform (DCT) taking into account noise present in these images. Quantization step is set fixed and proportional to noise standard deviation to provide compression in optimal operation point if it exists ...

Satisfied-User-Ratio Modeling for Compressed Video

IEEE Transactions on Image Processing, 2020
With explosive increase of internet video services, perceptual modeling for video quality has attracted more attentions to provide high quality-of-experience (QoE) for end-users subject to bandwidth constraints, especially for compressed video quality. In this paper, a novel perceptual model for satisfied-user-ratio (SUR) on compressed video quality is

Compression Ratio and Multifuel Capability

SAE Technical Paper Series, 1964
<div class="htmlview paragraph">This paper describes tests conducted to determine the effect of increased compression ratio on the multifuel capability of a standard diesel engine. The tests included power and cold starting capability checks, and it was found that the thermal efficiency was increased, combustion at full-load was improved, and ...

Generalized Equation for Compression Ratio

Journal of Testing and Evaluation, 1988
Abstract For highly compressible normally consolidated saturated soil the compression index, Cc, is not constant over the entire pressure range. However, the ratio of the compression index and the initial specific volume, generally known as the compression ratio, appears to be constant.

Talbot array illuminators with optimum compression ratio

Optics Letters, 1996
We describe Talbot array illuminators that generate, at fractions of the Talbot distance, arrays of bright spots with optimum compression ratio. We compare the performance of these Talbot array illuminators with that of an array of parabolic lenses.
