Compressed sensing (CS) is a recent mathematical technique that leverages the sparsity in certain sets of data to solve an underdetermined system and recover a full set of data from a sub-Nyquist set of measurements of the data. Given the size and sparsity of the data, radar has been a natural choice to apply compressed sensing to, typically in the fast-time and slow-time domains. Polarimetric synthetic aperture radar (PolSAR) generates a particularly large amount of data for a given scene; however, the data tends to be sparse. Recently a technique was developed to recover a dropped PolSAR channel by leveraging antenna crosstalk information and using compressed sensing. In this dissertation, we build upon the initial concept of the dropped-channel PolSAR CS in three ways. First, we determine a metric which relates the measurement matrix to the l2 recovery error. The new metric is necessary given the deterministic nature of the measurement matrix. We then determine a range of antenna crosstalk required to recover a dropped PolSAR channel. Second, we propose a new antenna design that incorporates the relatively high levels of crosstalk required by a dropped-channel PolSAR system. Finally, we integrate fast- and slow-time compression schemes into the dropped-channel model in order to leverage sparsity in additional PolSAR domains and overall increase the compression ratio. The completion of these research tasks has allowed a more accurate description of a PolSAR system that compresses in fast-time, slow-time, and polarization; termed herein as highly compressed PolSAR. The description of a highly compressed PolSAR system is a big step towards the development of prototype hardware in the future.
We processed reported R(T, Bappl) datasets for several annealed highly compressed hydrides by using Eq. (12) to extract Bc2(T) datasets. The obtained datasets were fitted to Eq. (11), and the deduced values are given in Table I. These materials are as follows:
- Sulfur superhydride H3S (P = 155 and 160 GPa), for which the raw data were reported by Mozaffari et al.31
$\mathbfQ:$ While teaching "Real Gases", my professor remarked last day that "Liquid phase is a highly compressed gaseous phase." But he did not explain the reason behind it and left it as food for our thought.
Now I can see from the graph that a certain finite amount of pressure needs to be applied in order that we can change the gaseous state from vapor to liquid. Ideal gases have considerable or high compressibility while ideal liquids are almost incompressible. But still can I call this "highly compressed"? So how do I prove the statement made by my professor?
When I create PNG files with very small disk size, I tend to wonder if the file size becomes less important than the time viewers would need to decompress the image. Technically that would be trivial too, but I've wondered about it for a long time. We all know that more-compressed PNG images take longer to compress, but do they take longer to decompress?
I then wrote a script to convert the image from png to tif (on the assumption that TIF is a relatively uncompressed file format so quite fast) 200 times and timed the output.In each case I ran the script quickly and aborted it after a few seconds so any system caching could come into effect before running the full test, thus reducing the impact of disk io (and my computer happens to use SSD which also minimizes that impact. The results were as follows:
But, this does not take into account the time taken to download the file. This will, of-course, depend on the speed of your connection, the distance to the server and the size of the file. If it takes more then about 0.5 seconds more to transmit the large file then the small file, then (on my system - which is an older ultrabook, so quite slow thus giving a conservative scenatio), it is better to send the more highly compressed file. In this case - this means sending 5.8 megabytes a second, which equates to - very roughly, 60 megabits per second - excluding latency issues.
Conclusion for large files - if you are on a lightly used LAN it is probably quicker to use the less compressed image, but once you hit the wider Internet using the more highly compressed file is better.
Short cycle times and highly compressed concrete block products: These are just two of the many advantages of the production process on hydraulic presses. Now widespread, the range includes fine-grained exposed aggregate concrete products and smooth slabs with ground or fine-blasted surfaces. In the hydraulic pressing process, a relatively liquid concrete layer is pressed together with an earth-moist substrate. The properties of the first concrete layer and thus the later stone surface make them suitable for reproducing the finest textures, in a similar way to a wetcast concrete.
This is where WASA HERMETIC with its highly wear-resistant polyurethane liners comes in. The liners are produced from a two-component casting resin in Shore A70 developed especially for this application. Moreover, because a two-millimeter-thick steel sheet on the back of the liner ensures very high dimensional stability, the polyurethane liners can be placed in any hermetic rotating table press.
