TLDR
The provided compressed bitstreams were uncompressed using provided software and the resulting sequences were compared to the original ones in terms of PSNR and it seems that last frames from some cameras give significantly worse PSNR than the rest of frames.Abstract:
The provided compressed bitstreams were uncompressed using provided software and the resulting sequences were compared to the original ones in terms of PSNR. Additionally, the sequence Ballroom was compressed using the provided software. Resulting bitstreams were processed as the ones provided by Sejong/ETRI to verify the whole chain of coding and decoding. The results obtained at Poznań University of Technology are included in the accompanying Excel file. They are the same as the ones provided by Sejong/ETRI, except for sequences Race1 and Flamenco2 results. The results for them are slightly worse than the ones presented by Sejong/ETRI. The difference is less than 0.05 dB. It seems that last frames from some cameras give significantly worse PSNR (about 10dB less than the rest of frames). The cause of this difference is unknown.read more

Keeping Quality of Use of Fresh 'Kurdistan' Strawberry by UV-C Radiation
TL;DR: In this paper, a strawberry was exposed to different doses (0.25 and 0.5 kJ/m ) of ultraviolet-C (254 nm, UV-C) radiation and stored up to 7 days at 1 5°C.

A new formal and analytical process to product modeling (ppm) method and its application to the precast concrete industry
Ghang Lee,Charles M. Eastman +1 more
TL;DR: The theoretical goals of this study are to provide a scientific foundation to bridge the requirements collection phase and the logical modeling phase of product modeling and to formalize the derivation and normalization of a product model from the processes it supports.

Using web-based personalization on spatial data warehouses
TL;DR: The great advantage of this approach is that each decision maker can easily include spatial data according to their own needs at conceptual level, while they can also conceptually get the right spatial schema instance avoiding exploring in a large and complex SDW.

Compression algorithms for dummy-fill VLSI layout data
TL;DR: This work proposes and assess a number of lossless and lossy compression algorithms for dummy fill based on the building blocks of JBIG approaches, and proposes a technique of achieving one-sided loss by solving an asymmetric cover problem that is of independent interest.

Risk Analysis and Modelling of Autonomous Marine Systems
TL;DR: This paper investigates how far the current ship risk models for ship-ship collision, ship-structure collision, and groundings are applicable for risk assessment of MASS.
