Application of Compressive Sensing for Sampling and Reconstruction of MRI Images
Abstract: In recent years, a new theory of compressive sensing has evolved which asserts that super resolved signals and images can be recovered with far fewer samples than that demanded by the Nyquist sampling theorem. It is required that the signal being sensed has a low information-rate meaning that it is sparse in original or some transform domain. Former approaches capture the complete signal and process it to extract the information. …

Flame Spraying of Polymer-Abrasive Composites
Abstract: Polymer-based abrasive tools are distinguished by higher elasticity and resistance to chemically active media compared to tools with metal and ceramic binders. The former are effective at processing complex-profile and non-rigid surfaces. Tools based on coatings containing abrasive phenol- formaldehyde/epoxy resins and vulcanites are characterized by high cost and toxicity. In this paper, a study of composite flame-sprayed coatings, consisting of thermoplastic polymers and silicon carbide (volume ratio of 50-50), …
